During the Christmas shopping rush in London， the interesting story was reported of a tramp （流浪汉） who， obviously though no fault of his own， found himself locked in a well-known chain store late on Christmas Eve. No doubt the store was crowded with last-minute Christmas shoppers and the staff were dead beat and wanting to get home. Probably all the proper safety checks were made before the store was locked and they left to enjoy the three-day holiday untroubled by customers anxious to get last-minute Christmas presents.

However ridiculous that may be， the tramp found himself alone in the store and decided to make the best of it. There was food， drink， bedding and camping equipment， of which he made good use. There must also have been television sets and radios. Though it was not reported if he took advantage of these facilities， when the shop reopened he was discovered in bed with a large number of empty bottles beside him. He seemed to have been a man of good humor as indeed tramps very commonly are.

Everyone else was enjoying Christmas， so he saw no good reason why he should not do the same. He yielded （屈服） himself cheerfully， and was taken by the police. Perhaps he had had a better Christmas than usual. He was sent to prison for seven days. The judge awarded no compensation （賠偿） to the chain store for the goods the tramp had used. They had， in his opinion， already received valuable free advertisement from the story revealed in the newspaper and on television. Perhaps the judge had had a good Christmas， too.

4. The tramp was locked in the store ___ .

A. for 7 days B. on purpose

C. by accident D. for safety reasons

5. What does the underlined phrase “dead beat” probably mean？

A. Angry. B. Exhausted.

C. Forgetful. D. Careless.

6. When he was arrested， the tramp ___ .

A. was drunk B. made no resistance

C. felt himself wronged D. was confused

7. Why did the judge award no compensation to the chain store？

C. The store was responsible for what happened.

D. The report of the event benefited the store a lot.

Experts say that if food were a country， it would rank second behind the US as one of the biggest greenhouse gas polluters. The reason is the rising demand for meat. Animal farming is responsible for 14.5 percent of global greenhouse gas methane emissions （甲烷排放）. While cows are the worse contributors， pigs， sheep， donkeys and other animals play a part as well.

Animal agriculture also causes land to become damaged， water to be polluted and forests to get destroyed. Now experts are advocating substituting （代替） some of the beef， chicken， or pork with ordinary insects！

Insects， which grow into adults within a matter of months， if not weeks， are ready for consumption much faster than domestic （驯养的） animals. They also require much less room， use less water and food， and produce far less greenhouse gas than animals.

Of the 1.1 million insect species worldwide， scientists have identified 1，700 as eatable. Among them are ants， grasshoppers， grubs， and earthworms. Just like animals， each insect has a different taste. Tree worms taste just like pork， and grubs are similar to smoked meat.

While eating insects might be a new concept for Western people， over 2 billion people worldwide consume insects as a regular part of their diet. Besides being delicious， insects are high in protein， have very few calories， and are free of the saturated （饱和的） fat found in animal meat. Insects can be prepared in many ways. Creative cooks can use them to cook protein-rich soup， make baked treats， and even fry a few with vegetables. So eat insects—both your body and Mother Earth will thank you for it！

8. What animals are responsible for the most global methane

emissions？

A. Cows. B. Pigs. C. Sheep. D. Donkeys.

9. How is Paragraph 3 developed？

A. By explaining reasons. B. By giving examples.

C. By providing facts. D. By making comparisons.

10. What do tree worms taste like？

A. Pig meat. B. Tomato soup.

C. Fresh vegetables. D. Fried chicken.

11. What can be inferred from the last paragraph？

A. Insects contain various vitamins.

B. Few people eat insects regularly.

C. Ordinary insects are low in saturated fat.

D. Eating insects is good for us and our planet.

D

Green tree ants are important builders in the rainforest. The native forest of Thala Beach Nature Reserve is the natural home of these insects.

They climb all over the tree that contains their nest and protect it from enemies with great fierceness. The ants are often in the fruit trees of Tropical North Queensland. When an animal tries to help themselves to some tasty fruit， they find themselves attacked by a powerful， frightening army of green tree ants！ Their bite is not very painful but many ants attacking at the same time can be extremely uncomfortable.

The nests are large and constructed by sticking the leaves at the end of branches together to create a home looking roughly like a globe. Most of the nest construction and weaving （編织） is conducted at night. A mature colony of green tree ants can hold as many as 100，000 to 500，000 workers and may include as many as 12 trees and contain as many as 150 nests.

However， the ants are so busy that they fail to spot a dishonest figure. There is a spider called the Salticid spider， or the jumping spider， as they are sometimes referred to， which has excellent eyesight and is only active during daylight， weaving a protective covering of silk to spend the night in. Interestingly， the Salticid spider does not look like a green tree ant. Instead， it chemically copies green tree ants smell. Effectively pretending to be an ant， it goes into the green tree ants nest， enters the nursery and feasts on their babies. Green tree ants dont have good eyesight and smell everything with their antennae （two long thin parts on an ants head）. Therefore， the ants think the spider is another ant and ignore its presence within the nest.

12. What does Paragraph 2 mainly tell us about green tree ants？

A. They leave painful bites.

B. They have good defenses.

C. They often start wars for food.

D. They like tasty fruit very much.

13. What is special about the green tree ants nest？

A. It is made of leaves.

B. It is reconstructed yearly.

C. It takes years to build one.

D. It can hold up to 500，000 ants.

14. Why do green tree ants regard the Salticid spider as another ant？

A. It looks like them.

B. It has a similar smell.

C. It can make familiar sounds.

D. It can communicate with them.

15. What can we learn about the Salticid spider？

A. It is harmful to fruit trees.

B. It protects the green tree ants.

C. It is the green tree ants enemy.

D. It helps the green tree ants build nests.

Does meeting new people make you nervous？ If so， you are not alone. But making a good first impression isnt as hard as you might think. It just involves a few simple choices.

Look your best.

But you dont need to look like a model to make a good impression. You just need to take care of yourself. Make sure your clothing is clean， not wrinkled and appropriate for the situation.

Stand tall.

The way you stand， sit and move tells others a lot about you. Standing up straight makes you look and feel confident. When you approach someone， make eye contact and smile to show youre friendly and interested.

Speak up.

Speak loudly and clearly enough so that people dont have to struggle to hear you. If you dont know what to say， ask questions.  When people are talking， pay attention to what theyre saying rather than planning what youll say next. And if youre not sure what they mean， ask！

Value people.

Most importantly， show people you care. Your concerns for them will be obvious if you smile and listen carefully.  Dont keep them waiting. Everyone you meet is important. So make eye contact， smile and greet them. Theyll appreciate it and others may be watching.

A. Respect other peoples time， too.

B. And remember， you are important， too.

C. Then greet them with a firm handshake.

D. Most people enjoy talking about themselves.

E. Dont forget little things like brushing your teeth.

F. Obviously your appearance influences peoples impression

of you.

job interview.

A thief who dropped a winning lottery ticket （彩票） at the scene of his crime has been given a lesson in honesty. His victim， who picked up the ticket and claimed the￡25，000 prize， managed to find him， and handed over the cash. The robbery happened when maths professor Vinicio Sabbatucci， 58， was changing a tyre on an Italian motorway. Another motorist， who stopped to “help”， stole a suitcase from his car and drove off. The professor found the dropped ticket and put it in his pocket before driving home to Ascoli in eastern Italy.

Next day， he saw the lottery results on TV and， taking out the ticket， realized it was a winner. He claimed the 60 million lire prize. Then he began a battle with his conscience. Finally， he decided he could not keep the money despite having been robbed. He advertised in newspapers and on the radio， saying， “Im trying to find the man who robbed me. I have 60 million for him—a lottery win. Please meet me.”

Professor Sabbatucci received hundreds of calls from people hoping to trick him into handing them the cash. But there was one voice he recognized—and he arranged to meet the man in a park. The robber， a 35-year-old unemployed father of two， gave back the suitcase and burst into tears. He could not believe what was happening. “Why didnt you keep the money？” he asked. The professor replied， “I couldnt because its not mine.” Then he walked off， spurning the thiefs offer of a reward.

In the middle of the 20th century people were worried about whales. The number of whales killed worldwide came up to 66，000 per year. However， people werent worried about the whale as an endangered animal. Instead， they were worried about the whale industry， which would disappear if there were no whales. In 1946， the International Whaling Commission was established. It limited the whale hunting for every country and controlled the whale industry. They set a worldwide law against hunting whales with only two exceptions： the hunt for scientific research and “aboriginal whaling”. Aboriginal whaling allows some countries to hunt a limited number of whales because it is a part of their culture. Some countries dont care about the law; they make excuses to hunt whales and sell the products. They only care about the money.

Many fishermen complain that dolphins， also a kind of whale， steal their fish. Therefore， they kill thousands of them. In reality there are so many fishermen who steal the fish from each other. Some whale hunters say that they catch the animals for scientists. They have to research what whales are eating. For that， they kill them and look into their stomach. The truth is that they only want to sell the meat. Today scientists want to observe live whales for their research.

Many whale families are not protected and thousands of them are killed. The pollution of the oceans increases fast. Many whales get sick and die. The human being has killed 90%—95% of many whale families. Others are already extinct.

Today some international organizations try to protect whales. They make reports to explain how important and endangered whales are. Now people are becoming more interested in whales and a completely new industry has developed， whale watching， which you may want to learn about.

9. Why is aboriginal whaling allowed in some countries？

A. There are many whales in the countries.

B. It is a part of the culture.

A. Dolphins steal their fish.

B. There are so few dolphins for them to hunt.

C. They want to make an excuse for killing dolphins.

D. People have misunderstood their purpose of hunting dolphins.

Have you ever wished you could see in the dark as well as an animal？ In action movies， we often see characters wearing special glasses that reveal things that cant be seen in darkness. Everything looks green， but we can see the shapes and outlines clearly. As a matter of fact， this is somewhat similar to the way animals night vision （視力） works.

You may have noticed eyeshine in pictures of animals， or seen it for yourself when light hits an animals eyes. Dogs， cats， and many other animals have tissue called the tapetum lucidum （光神经纤维层） in each eye. The purpose of this tissue is to reflect light deeper into the eye. For many animals， it leads to their excellent night vision， and it helps them hunt.

Different types of animals have different colors of eyeshine. The light reflecting back from the eyes of dogs and cats is likely to be yellow. Rats and birds usually have eyes that shine red. Other animals eyes may reflect white， yellow， green， or pink light. In each case， the color is related to the type of cells that make up the tapetum lucidum， as well as the chemicals inside the cells.

Eyeshine has the function of improving animals night vision， but humans have found other uses for it. For example， when people are searching for certain types of animals， their eyeshine may be helpful in recognizing or discovering them. Also， eyeshine has inspired humans to invent substance that reflects light at night. Strips containing this substance are used to warn us of safety risks such as raised parts of roads. Even though humans cannot see so well at night， we have still found ways to benefit from this amazing animal feature.

12. How does the tapetum lucidum help animals night vision？

A. It sends out light in the dark.

B. It makes everything appear green.

C. It reflects light back into the eyes.

D. It enables their eyes to change colors.

13. How does the writer develop Paragraph 3？

A. By providing reasons. B. By giving examples.

C. By following space order. D. By doing scientific tests.

14. What can we learn about scientists research on eyeshine？

A. Theyve put it to practical uses.

B. Theyre using it to protect some animals.

C. Theyre trying to include more animal types.

D. Theyve invented special glasses based on it.

15. What is the text mainly about？

A. How animals night vision helps them hunt.

B. Different colors of animals eyes.

C. How animals see in the dark.

D. Eyeshine and its benefits.

When our dog， Angel Michelle， was diagnosed with bone cancer in June of 2016， my family was shocked. She was only eight years old， and1the slight injury on her right knee， she looked and behaved normally.

As we slowly drove down the street on that cold December evening we noticed the light in front of a door.

“This must be the house，” I1（tell） our “Positive Teens in Action” group.

We pulled up， walked up the steps，2knocked on the door. We heard a faint voice3inside， “Come on in. The door is open.”

We opened the door and saw an elderly woman4（sit） in a rocking chair. “Ive been expecting you，” she said5（weak）. That was Rose， one of our Meals-on-Wheels6（stop） I had arranged. We handed Rose the gifts the teens had prepared7（early） that evening. Then I asked Rose8carols （頌歌） she would like to hear. Rose was getting more9（cheer） as she joined in singing each song she loved.

Later， as we hugged Rose good-bye she said to me， “The other day I asked God if it would be possible10（send） some Christmas Carolers to my home. Thank you for being the answer to my Christmas prayer （祈祷）.”

Wow， how great it is to have the opportunity to be the answer to someones Christmas prayer！

I was going home by bike in a cold afternoon when my bike broke down. As I was wondering how to do， an old man came over. He offered to help me and soon my bike repaired. I thanked him but asked how to repay him. She shook his head and then told me a story about how a boy had helped him two year before. His story moved me deep. I looked at the man， with my eyes filling with tears. I never thought he could keep such a little thing in the mind for years. Only then do I begin to believe that one good turn deserves another.

Nine months ago， I was packing my daughters backpack with new school supplies， wondering how I was going to send her off to kindergarten. I stood on the playground， tears pouring down my face because I wasnt ready for this first day of kindergarten—but she was ready. Today I will be standing on the playground， once again with tears， because this precious time went by too quickly. This week I realized that I never told you “thank you”. I dont know how to express a mothers thanks in the way a teacher deserves.

We first met you at the open house the week before school started and I immediately knew you would be the type of teacher we would appreciate forever. While the students lined up for the day， you touched each one on the shoulder as you greeted them. If a student was having a tough morning， you quietly held her hand and walked her into the school.

I got to know you as I volunteered in the lunch room. You made sure your students were all ready for lunch before you went on your own lunch break. You kept track of their big things and small things， because as a veteran kindergarten teacher， you know that the small things are the big things. I loved the way you made each student feel special. You helped them fall in love with school which is so important at the start.

To all of the teachers in the world who are like you， I wish you knew how grateful parents are for you. We adore you， respect you， and appreciate you. We dont tell you enough—we probably dont tell you ever. I wish we could take you with us to the next 12 grades.

In a mountainous area of Brazil， there is a kind of beautiful butterfly which can kill men. If people meet them， they will come down in great quantities to bite and kill， sucking blood and eating flesh through the wounds they cause.

In June， 1966， a boy named Marl Andre who went into the mountains in search of butterfly specimens （標本） was killed by these butterflies. A country boy saw him as he was just about to raise （举起） his net to catch a butterfly. Suddenly thousands of butterflies came down upon him， covering him all over. The boy struggled and cried as he tried to free himself from their attack. Finally he fell senseless to the ground. Police examined his body and proved that he had died of bites by butterflies.

In New Guinea， there is a kind of needlefish which also kills men. Because it likes light at night， it will swim near the lights of fishing boats， then suddenly shoot out of water like an arrow to its target， and force its 3-inch sharp mouth into a human body. Often people are thrust （戳） in the eye， or through the chest or stomach， resulting in death. Sometimes it will even attack the people in a fishing boat in broad daylight.

In the past， people who graduated from college felt proud of their academic achievements and confident that their degree would help them to find a good job.

However， in the past few years the job market has changed greatly. This years college graduates are facing one of the worst job markets. For example， Ryan Stewart， a graduate of San Jose State University， got a degree in religious studies， but he has not got any job offers. He points out that many people already working are getting laid off and dont have jobs， so its even harder for new college graduates to find jobs.

A few years ago， the future looked bright for his class. There were many high-tech job opportunities， graduates received many job offers， and they were able to get jobs with high salaries and benefits such as health insurance and paid vacations. However， “Times have changed. Its a new markets，” according to an officer of the university.

The officer says students who do find jobs started preparing two years ago. They worked during summer vacations， they have had several short-time jobs， and they majored in fields that are still paying well， such as accounting or nursing.

Even teaching is not a safe profession now. Ryan Stewart wanted to be a teacher， but instead he will probably go back to school in order to become a college teacher. He thinks college teaching could be a good job even in a bad economy.

In conclusion， these days a college degree does not lead to a good job with a high salary. Some students can only hope that the value of their degree will increase in the future.

12. What did a college degree mean to people in the past？

A. It was evidence of their professional skills.

B. It built up their confidence in the job market.

C. It would help them to start an academic career.

D. It would guarantee their quick lift in their position.

13. Why hasnt Ryan Stewart got any job offer？

A. There are too many graduates of his major.

B. He wants to find a job with high salary.

C. He has no university degree.

D. The job market has changed greatly.

14. Why does Ryan Stewart want to be a college teacher？

A. Teachers are well-paid.

B. He majored in teaching in the university.

C. The career wont be influenced by economy.

D. The job is less challenging than high-tech ones.

15. What can be concluded from the text？

A. Graduates must prepare early to find jobs.

B. A college degree can still lead to a good job.

C. The value of a college degree has reduced now.

D. College students are encouraged to work part-time.

Roller skating is easy and fun， and today it is popular throughout the world. People roller skate outside on paths and roads， and inside in rinks. But a long time ago， it wasnt easy at all. Before 1750， the idea of skating didnt exist. That changed because of a man named Joseph Merlin. Merlins work was making musical instruments. In his spare time he liked to play the violin. Joseph Merlin was a man full of ideas and dreams. People called him a dreamer.

One day Merlin received an invitation to attend a fancy dress ball. He was very pleased and a little excited. As the day of the party came near， Merlin began to think how to make a grand entrance at the party. He had an idea. He thought he would get a lot of attention if he could skate into the room.

Merlin tried different ways but only to make himself fool. Finally， he decided to put two wheels under each shoe. These were the first roller skates. Merlin was very proud of his invention and dreamed of arriving at the party on wheels while playing the violin.

On the night of the party Merlin rolled into the room playing his violin. Everyone was surprised to see him. There was just one problem. Merlin had no way to stop his roller skates. He rolled on and on. Suddenly， he ran into a huge mirror that was hanging on the wall. Down fell the mirror， breaking into pieces. Nobody forgot Merlins grand entrance for a long time！

4. Why did people think that Merlin was a dreamer？

A. He often made surprises.

B. He was a gifted musician.

C. He was full of imagination.

D. He invented the roller skates.

5. Merlin put wheels under his shoes to ___ .

B. draw the guests attention

C. arrive at the party sooner

D. test his invention

6. What can we learn about Merlin according to the last paragraph？

A. He got himself into trouble.

B. He succeeded unexpectedly.

C. The party guests took him for a fool.

D. His roller skates needed further improvement.

Steven Stein likes to follow garbage trucks. His strange habit makes sense when you consider that hes an environmental scientist who studies how to reduce litter， including things that fall off garbage trucks as they drive down the road. What is even more interesting is that one of Steins jobs is defending an industry behind the plastic shopping bags.

Americans use more than 100 billion thin-film plastic bags every year. So many end up in tree branches or along highways that a growing number of cities do not allow them at checkouts. The bags are prohibited in some 90 cities in California， including Los Angeles. Eyeing these headwinds， plastic-bag makers are employing scientists like Stein to make the case that their products are not as bad for the planet as most people assume.

Among the bag makers argument： many cities with bans still allow shoppers to purchase paper bags， which are easily recycled but require more energy to produce and transport. And while plastic bags may be ugly to look at， they represent a small percentage of all garbage on the ground today.

The industry has also taken aim at the product that has appeared as its replacement： reusable shopping bags. The stronger a reusable bag is， the longer its life and the more plastic-bag use it cancels out. However， longer-lasting reusable bags often require more energy to make. One study found that a cotton bag must be used at least 131 times to be better for the planet than plastic.

Environmentalists dont dispute （質疑） these points. They hope paper bags will be banned someday too and want shoppers to use the same reusable bags for years.

8. What has Steven Stein been employed to do？

A. Help increase food sales.

B. Recycle the waste material.

C. Stop things falling off trucks.

D. Argue for the use of plastic bags.

D. Is there any time when they hide from you？

E. This may seem a little contradictory to the last tip.

F. We should open our hearts and take action to cure the

wounds.

G. When we run away from sadness， it gets stronger and

more real.

I feel certainly about the chemistry test that they are going to have tomorrow. The teacher has already told us exactly which to study and I think my grades on homework has been good. As a matter of the fact， I think chemistry has always been one of the subjects that I enjoy most. Susan or I have already spent two hours review pages 115—140 tonight. We are going to devote another hour in practising with some of the sample problem. Then I will ready for the test.

What is Cloning？

何为克隆？

Cloning is the asexual production of an exact copy of an original. So for example， one could use cloning to produce the exact copy of a single cell. The cell copy would be identical to the first cell and would have the same exact DNA sequence. In many cases， cloning has been used to reproduce type specific cells. In some instances， cloning of an individual organism， like the sheep， Dolly， has been possible.

Unlike reproduction that involves two “parents”， such as a male and female plants， cloning has a single parent. This is often used in reproducing certain plants. Certain plants have undergone cloning processes for thousands of years， but they do not play a part in the ethical debates that surround cloning of animals， and most particularly humans.

For example， reproductive cloning of animals was first attempted in the 1950s. The sheep Dolly was cloned in 1996. Dollys parent had DNA transferred into an egg that had its nucleus removed. This is called a somatic cell nuclear transfer. The cell was then treated with chemicals and stimulated to grow so than an almost exact replicate of the cloned sheep was born.

克隆就是通过无性繁殖，对原体的精确复制。举例来说，细胞就可以被完全复制。生成的细胞与原细胞一模一样，甚至基因链也相同。普通实验都是克隆特型细胞。当然，克隆羊多莉的成功表明有机体的克隆也是可行的。

有些植物分雌雄，其后代有父有母，而克隆产物不同于此，只有一个父源。有很多植物也是单性繁殖，数千年如此而不会有伦理问题;可一旦涉及动物，特别是人类的克隆，伦理问题便凸显了。

有例可证，动物克隆的尝试始于20世纪50年代，多莉于1996年被克隆。将其父源基因移植到一去核卵子中，这一技术被称为体细胞核移植。该细胞随之采用多种化学物质进行培育，最终得到了对其父源完全克隆的多莉。
