时间状语从句
一、概述
概念:在复合句中,由时间连接词引导的表示时间的从句叫做时间状语从句。
一般来说,时间状语从句常由连词when,while, as, before, after, as soon as或until,since等引导。
注意:如从句表将来时,采用“主将从现”原则。
eg. I will go to the cinema as soon as I finish my homework.
When I grow up, I will join the army.
二、引导词的用法与辨析
(1) when引导的谓语动词可以是延续性的动词,也可瞬间性动词。
eg:When she came in, I stopped eating. (瞬间性动词)
When I lived in the countryside, I used to carry some water for him.(延续性动词)
(2) while引导的动词必须是延续性的,并强调主句和从句的动作同时发生(或者相对应).
并且while有时还可以表示对比。
e.g:While my wife was reading the newspaper, I was watching TV.
(3)until 引导肯定句时,谓语需用延续性动词,意为“直到….”;
引导否定句时,谓语动词是延续性或瞬间性动词,意为“直到….才….”
eg. He waited until all the people left.
I didn't go to bed until Mum came back.
(4)as soon as表示“一……就……”,强调动作紧密相连。如:
We start to sing as soon as it is 12 o’clock.
We began to work as soon as we got there.
(5)由before和after引导的时间状语从句。
It will be four days before they come back. 他们要过四天才能回来。
Einstein almost knocked me down before he saw me. 爱因斯坦几乎把我撞倒才看到我。
After you think it over, please let me know what you decide. 你仔细考虑过以后,告诉我你是怎样决定的。

One August afternoon, Richard Allen dropped off his last passenger, Mrs. Carey, lifting two grocery bags, he followed her across the yard and stood on the step of her house. Glancing up, he saw a large wasp nest under the roof. Allen had heard that wasps can became more likely to sting in summer. He mentioned this to Mrs. Carey, who had opened the door.
“Oh, they don’t bother me,” she said lightly. “I go in and out all the time.”
Anxiously, Allen looked at the nest again—to see the wasps flying straight at him. “Hurry!” he shouted to Mrs. Carey. “Get in!”
She stepped quickly inside. Allen ran for his mini-bus. Too late; they were upon him. Just as he jumped aboard, half a dozen red spots showed on his arm, and he felt more on his back and shoulders.
As he was driving down the road, Allen felt as if something was burning at the back, and the “fire” was spreading forward toward his face. And immediate anxiety took hold of him. Allen knew that stings could cause some persons to die. But he had been stung the previous summer and the after-effects soon passed. However, what he didn’t know was that the first sting had turned his body into a time bomb waiting for the next to set off an explosion.
Miles from the nearest medical assistance, Allen began to feel his tongue thick and heavy and his heartbeat louder. Most frightening, he felt his breathing more and more difficult. He reached for the radio mike, trying to call the mini-bus centre, but his words were hardly understandable. Signals were also poor that far out. He knew a rescue team was on 24-hour duty at the Amherst Fire Department’s north station. So his best chance was to make a run for it.
Rushing down the mountain, Allen tried not to panic, focusing his mind on each sharp turn. He was almost through the last of them when he felt sure he was going into shock. Just then he reached for the radio mike again.
“Call fire station,” he shouted concentrating to form the words. “Emergency. Bee sting. Emergency. There in ten minutes.”
“Five-ten,” the center replied.
Hold on, Allen thought. Keep your eyes open. Breathe. Keep awake.
At last he reached the station. Two firemen ran out. Allen felt their hands grasp him before he hit the ground. You made it, he thought.
26. It is mentioned in the passage that wasps are more likely to attack when_______.
A. there are huge noises B. strangers are getting very near
C. the air is filled with food smell D. the hottest season comes around
27. Allen didn't know that if stung by wasps again, he would___________.
A. have no after-effects B. suffer from sharper pain C. lose his life D. became much weaker
28. Allen failed at the first time when he tried to send his message to the mini-bus center because__________.
A. he was unable to speak clearly B. his radio equipment was poor
C. he was in a state of shock D. no one was on duty
29. Which of the following is NOT true according the story
A. Allen drove to the fire station because he knew there was a rescue team there.
B. Allen managed to make his request of help clear though he had difficulty talking by then.
C. The mini-bus centre did help in that they got the rescue team ready before Allen arrived.
D. Allen shouldn’t have looked at the wasps when he helped Mrs. Carey.
30. Which would be the best title for the passage
A. Allen, a Helpless Driver B. Wasps, Bloody Killers C. A Race against Death D. War against Wasps
