小朋友,你们知道吗?在英语王国的“助动词”家族里,生活着颇有威望的“三大领导”——do,does,did。正是由于它们的正确“领导”,一般现在时和一般过去时的疑问句和否定句才会那么井然有序。看,“秘书小助”正在整理它们的资料呢!
助动词do,does用于一般现在时,其过去式did用于一般过去时。它们三者通常用在疑问句和否定句中,并且后面的动词要用原形。
1. 能帮助构成否定句,否定形式为:do not=dont,如:
I dont like playing the violin. (否定句)
我不喜欢拉小提琴。
My parents dont go to work at the weekends. (否定句)
我父母周末不工作。
Dont swim in the river!(否定祈使句)
不要在这条河里游泳!
Its hot!Dont close the door!(否定祈使句)
很热,不要关门!
2. 能帮助构成疑问句,如:
Do you have any hobbies? (一般疑问句)
你有一些業余爱好吗?
What do people usually do at Spring Festival? (特殊疑问句)
人们通常在春节做什么?
能帮助构成否定句和疑问句,否定形式为: does not=doesnt,如:
My sister doesnt like toy planes. (否定句)
我的妹妹不喜欢玩具飞机。
Does Nick often go swimming with you? (一般疑问句)
尼克经常和你去游泳吗?
What does your father often do after supper? (特殊疑问句)
你爸爸晚饭后经常做什么?
否定形式为: did not=didnt,用法类似于do 和does,如:
I didnt go to school yesterday. (否定句)
昨天我没有去学校。
Did you watch the football match last Saturday? (一般疑问句)
你上周六看足球比赛了吗?
Where did you go last Childrens Day? (特殊疑问句)
去年儿童节你去哪儿了?
在使用do,does,did时,一定要注意分清句子的时态哦!一般过去时,用助动词did;一般现在时中,does用于主语是第三人称单数的情况,其余一律用do!
1. you often go to school by bus?
2. Mary and Lucy go to the zoo yesterday?
3. His father likes collecting stamps,but he like it.
4. —Did you go to the post office three days ago?
—No,I .
