BROOKSVILLE—Its the time of year again, when young bears are on their own for the first time. And that means more sightings where bears usually arent supposed to be.

This weekend, a 258-pound black bear took a brief tour of Brooksville, with police and firefighters chasing.

Another black bear, about 100 pounds, was spotted Saturday, crossing busy U.S. 19 near a retirement community in Spring Hill. Several other bear reports have come from Citrus County.

“It is really difficult to the younger bears to find their own land around here,” said Niki Everitt, Bear Hot Line director for the Gulf Coast Conservancy.

Brooksvilles bear first was spotted late Thursday crossing State Road 50, headed toward Tom Varn Park. Police and firefighters tracked the bear through the park and the Brooksville Quarry golf course. The bear then wound down the middle of Broad Street before being surrounded near Luigis Pizza. An official with the Florida Game and Fresh Water Fish Commission came with a tranquilizer spear(加入镇静剂的矛), planning to stick the bear by hand.

“The guy saw the size of the bear and figured that wasnt a great idea,” said Frank Phillips of the Brooksville Fire Department.

Emergency officials waited until a tranquilizer gun was brought from Land O lakes. The bear then got a free ride to the Chassahowitzka Wildlife Management Area.

“It is not unusual for bears to move into living areas this time of year,” experts say. Mothers give their male baby bears the boot once the youngsters are 2 years old. With living areas growing, the young bears keep finding smaller and smaller areas in which they can set up their own land. “Theyre trying to find a land of their own, where they wont get beat up,” said Rip Stalvey, a game commission spokesman.

Everitt said “People should not be too concerned about the recent bear sightings, since we have never had a bear attack in Florida.”

Black bears mainly eat the tender and fresh leaves of palms(棕榈树), as well as acorns and berries. Recent weeks of dry weather likely have reduced their food supply.

“If we dont get some relief soon,” Everitt said, “were probably going to see a lot more of it.”

1. Whats the main idea of this passage? ____.

A. Bear sightings in living areas worry people

B. Policemen try hard to get the bears controlled

C. People take up too much land from bears

D. Bears come out to disturb peoples life

2. Which of the following is true according to the passage? ____.

A. The 100-pound bear was caught near Luigis Pizza

B. The Gulf Coast Conservancy makes bears homeless

C. Brooksvilles was too large to be caught by hand

D. Bears frequently visit humans living areas

3. Bear sightings can usually be expected ____.

A. in the cold season B. in the warm season

B. find new homes for them

C. drive them away from home

D. keep them in safe places

Most of us are used to seasons. Each year, spring follows winter, which follows autumn, which follows summer, which follows spring. And winter is colder than summer. But the earth goes through temperature cycles over much longer periods than those that we experience. Between 65,000 and 35,000 years, the planet was much colder than it is now. During that time the temperature also changed a lot, with periods of warming and cooling. Ice melted during the warm periods, which made sea levels rise. Water froze again during the cold periods.

A new study from Switzerland, sheds light on where ice sheets melted during the ice age. It now seems that the ice melted at both ends of the earth, rather than just in either northern or southern regions.

This surprised the researchers from the University of Bern. Scientists have long assumed(假设) that most of the ice that melted was in the Northern hemisphere(半球) during the 30,000-year-long ice age. That belief was held because the North Pole is surrounded by land, while the South Pole is surrounded by the Antarctic Ocean. It is easier for ice sheets to grow on land. If surrounded by sea the ice can easily just slip into the ocean instead of building up.

The researchers used a computer model to look at ways the ice could melt and how it might affect sea levels. They compared these results to evidence of how temperatures and currents actually changed during that time. The model showed that if it was only in the Northern hemisphere that ice melted, there would have been a bigger impact on ocean currents(洋流) and sea temperatures than what actually happened. Studies suggest that melting just in the Southern hemisphere would have been impossible, too. The only reasonable conclusion, the scientists could make, was that ice melted equally in the North and the South.

It is still a mystery as to what caused the temperature changes that caused the ice to melt.

1. The North Pole is surrounded by land, while the South Pole is

surrounded by the Antarctica Ocean. So scientists thought that ____.

A. most of the ice melted in the Northern hemisphere

B. most of the ice melted in the Southern hemisphere

C. the North Pole is colder than the South Pole

D. the South Pole is colder than the North Pole

2. We can infer from the passage ____.

A. the ice can easily just slip into the ocean

B. volcanoes caused the ice to melt

C. melting just in the Northern hemisphere would have been impos- sible

D. researchers often use the computer models to keep their research work

3. The scientists are not sure ____.

A. how long the ice age lasted

B. where ice sheets melted during the ice age

C. what caused the temperature changes

D. what the earth is made up of

4. Which of the following is the best title? ____.

A. A Computer Model

B. Studies Show Ice Melted Equally in the North And the South

During the Ice Age

C. Most of the Ice Melted in the Northern Hemisphere During the

30,000-year-long Ice Age

D. A Survey Result

I recently returned from a trip to Denmark while producing a TV program about renewable energy for CBCs Nature Of Things. Today, Denmark produces 25 percent of its electricity using wind turbines(叶轮机). It hopes to be producing 50 percent of its electricity using the wind by 2020. As Torben Madse, vice-president of Vestas, the worlds largest producer of wind turbines, stated in an interview, “Where we have the best success with wind turbines is not necessarily where we find the best wind. It is where we have the political will.”

As the subject of the Pickering airport raised its ugly head this week with objection against the Greater Toronto Airport Authoritys suggestions to build an airport on the federal land, it occurred to me that rather than destroying this farm land, which is owned by the people of Canada, it should be turned into a wind farm to produce green energy. The class “A” agriculture land could still be farmed while the turbines contribute to our electricity needs.

For $1 billion, about 200 wind turbines could be fixed on the land and produce 550 megawatts of green energy. The project would also create jobs, which many local politicians keep crying for. The 200-tonne metal towers the turbines sit on would have to be fabricated locally. Building the solid foundation and the towers would create construction jobs. Skilled electrical jobs would be created as the turbines would have to be maintained over their 20-to-30-year life span. And like the Nystead wind farm off the coast of Denmark, a Pickering wind farm could attract tourists to the area.

A mistake was made years ago, when the land was expropriated(征用) for an airport. Lets correct that and make the right decision this time. A wind farm project on the federal land would benefit everyone. All we need is the political will.

1. In Torben Madses opinion, ____ play(s) a key role in producing electricity using the wind.

A. the best wind B. the best wind turbines

C. the government D. the producer of wind turbines

2. According to the passage, one of the advantages of producing elec- tricity using the wind is that ____.

A. it is pollution-free B. it is easy to produce

C. it saves labor D. it costs less

3. We can infer from the land mentioned in the passage is best for ____.

A. turbines B. tourism C. an airport D. farming

4. The underlined word “fabricated” (in Paragraph 3) means ____.

A. constructed B. strengthened C. heightened D. supported

Nature is full of color, from rainbows and roses to butterfly wings and peacock(孔雀) tails. Even the fruits and vegetables you eat have different colors: blueberries(蓝莓), red strawberries, green broccoli, and orange carrots.

Plants and animals often use color to attract attention. Thesubstance(物质) responsible for these colors belongs to a class of chemicals called antioxidants(抗氧化剂). Plants make antioxidants to protect themselves from the suns ultraviolet(UV)(紫外线的) light.

Ultraviolet light causes chemicals called free radicals(自由基) to form within plant cells. They can destroy parts of the plant. Free radicals also have damaging effects on human beings. Some of these effects like wrinkled(皱纹) skin, can be seen. The damage is caused by the free radicals attacking cells in our bodies. Certain cancers and heart disease are linked to free radicals.

Our bodies have natural defenses for fighting off free radicals. While were young, our defenses are pretty strong. However, they get weaker as we get older. The bodys built-in defenses can only go so far without extra help.

The key to fighting free radicals with fruits and vegetables is to mix and match colors. Its like sun screen(防晒剂) for the inside of your body. Go for a range of very bright colors. Colorful foods contain hundreds of healthy chemicals not found anywhere else. Research into how chemicals in blueberries affect the brains function in rats suggests that these chemicals may help our own brains work more efficiently.

Dont just blame the sun. Ultraviolet light isnt the only source of free radicals. If you breathe polluted air, such as smog, automobile exhaust(尾气), or wasted gas from a factory, you take in chemicals that also cause such damage. And, the body itself produces free radicals as it processes food.

1. Which of the following is NOT true? ____.

A. Antioxidants are responsible for plant colors

B. Plants often use colors to attract attention

C. Antioxidants can protect plants from UV light

D. Antioxidants help free radicals to attack plants

2. In which order do the following facts occur? ____.

A. Winkled skin can be seen

B. UV light causes free radicals to form

C. Free radicals damage cells in our bodies

D. The sun gives out UV light

A. a, b, c, d B. d, b, c, a C. c, a, d, b D. d, b, a, c

3. We need extra help to fight off free radicals form within fruits and vegetables because ____.

A. our bodies defenses are not natural

B. we are too young to defend ourselves

C. our defenses get weaker as we get older

D. our bodies built-in defenses can only go away

4. Which of the following cant cause free radicals to form? ____.

A. Colorful food B. UV light from the sun

C. Polluted air D. The body itself

Everyone would like to be a millionaire but can you imagine having over $30 million and only being 20 years old? Britney Spears from Kentwood, a small town in Louisiana, is an international pop superstar with not only $30 million but also $2 million house in LA. At her young age, she can look after her family financially all her life.

This year is a big year for Britney. She is currently on a 31-day tour of the US and every concert is a sell-out. That means she plays in front of a crowd of around 18,000 every time. Its a tiring schedule but brings great rewards. When touring, she goes to bed at around 1a.m. and then has a lie-in until 1 p.m. or 2 p.m. the next day. Her philosophy(人生哲学) is to take care of the body and be relaxed but always make sure you work hard and have fun.

Spears is not satisfied with only touring and selling nearly 40 million records, so she decided to branch out into the movie business and try a bit of acting. She made an appearance in “Austin Powers 3” in 2002 and she filmed a teenage comedy that was released in 2003. In this movie, she had a starring role. The movie was her own concept and she picked the writer.

In spite of the fact that she has not enjoyed the same popularity as a pop singer so far, she insists on trying more roles. For Britney, acting is another way to express herself and she is enthusiastic about it all. If her movies are successful, her bank account is sure to grow by another few million dollars but she has been quoted as saying she does it for the love, not for money.

1. Tickets for Britneys concert are ____.

A. booked in groups B. too expensive

C. not available D. all sold

2. The underlined word “you” in the second paragraph refers to ____.

A. a person in general B. a particular person

C. Britney herself only D. the reader

3. Which of the following is NOT true according to the passage? ____.

A. Though young, Britney is a superstar both on the stage and screen

B. While touring, Britney is so tired that she has to sleep more than usual

C. The teenage comedy was based on Britneys own ideas

D. Britney will be even more wealthy with her movies successful

4. According to Britney Spears, she works ____.

A. to be a great actress B. for the enjoyment

C. to be more famous D. for the love of singing
