Section ⅡGrammar时间状语从句和原因状语从句一、时间状语从句1．when, while和as(1)when引导时间状语从句的用法①when引导时间状语从句时，句中的谓语动词既可为延续性动作，也可为瞬时性动作，可用于主句和从句动作同时发生或从句动作先于主句动作发生。

例如：When I lived in the countryside, I used to go fishing with my fellows.(延续性动作)我住在乡下时，常和伙伴们去钓鱼。

When the lecture finished, the audience warmly clapped Yi Zhongtian.(瞬时性动作)演讲结束时，听众向易中天热烈鼓掌。

②when可以用作并列连词，其意义为“那时，这时”，相当于and at this/that time。

例如：We were having a meeting when someone broke in.我们正在开会，这时一个人闯了进来。

③when还表示原因，相当于since(既然；考虑到)。

例如：It was foolish of you to do it when you have realised its impossibility.既然你已意识到不可能做这件事，却去做了，真够愚蠢的。

温馨提示：当when引导的从句是系表结构，且主语和主句的主语一致，其表语又是一个名词时，就可以用以as引导的省略句来代替when引导的从句。

例如：As a young man (＝When he was a young man), he was fond of reading.他年轻时，喜欢读书。

(2)while的用法①while引导的状语从句中的动作必须是延续性的，侧重主句动作和从句动作的相比性。

例如：Don't talk with others while your mouth is full.吃东西时别对着别人说话。

②while作为并列连词，意为“而，却”，表示对比。

例如：I like staying at home on weekends, while my wife enjoys going shopping.周末我喜欢待在家里，而妻子喜欢去购物。

③while作从属连词，意为“尽管”，有时还等于although。

例如：While (Although) I am willing to help, I do not have enough time.尽管我乐意帮忙，但没有足够的时间。

(3)as的用法as引导的状语从句中谓语动词可为延续性动作，表示从句和主句两个动作交替进行或同时发生，可译为“一边……，(一边)……”或“随着……”。

例如：She hurried to work, looking behind at her son as she went out.她匆忙去上班，边出门边回头看儿子。

As time went on, he missed his parents more and more.随着时间的推移，他越来越思念父母亲。

2．every time, each time, next time, the first time等名词短语用来引导时间状语从句，表示“每次……，下次……”。

例如：Each time I met with difficulty, my teacher would help me.每次我遇到困难，老师都会帮助我。

The first time I climbed Mount Tai, I was impressed with her beauty.第一次爬泰山，我就被她的美景吸引住了。

3.before和since(1)before的用法①before表示“还未……就；不到……就；……才，还没来得及”。

例如：We hadn't run a while before Tom felt tired.我们还没跑一会儿，汤姆就累了。

Please note down before you forget.趁着没忘记，请记下来。

②It will be＋一段时间＋before...多久之后才……。

例如：It will be one month before I complete it.我一个月之后才能完成。

It won't be long before we graduate.不久我们就毕业了。

(2)since的用法①since从句的谓语动词一般是非延续性动词，主句的谓语动词是延续性的或者是反复发生的动作。

since从句的时态如果是一般过去时，相应地，主句的时态是现在完成时或是现在完成进行时。

例如：I have never heard of him since he left home.自他离家出走，我至今没听到他的消息。

They have been working for the factory since they came here.我们失去它)．4．Now_that_you_have_made_mistakes (既然你犯了错误), you should be punished.5．While_we_were_talking (当我们还在讲话时), the teacher came in.6．It_is/has_been_five_years (已经有5年了) since I last met my aunt.7．It_won't_be_long_before (不久之后) we have a holiday.8．He didn't leave until_it_stopped_raining (直到雨停)．Ⅰ.单句语法填空1．It will not be long before you become an excellent reporter.2．The head of the company promised to deal with the matter the moment he returned to his office.3．While we were studying abroad, we learned much about foreign culture and customs.4．The boy burst into tears immediately (immediate) he saw his mother.5．He looked at the plane taking off till/until it disappeared.6．He had no sooner finished his speech than the students started cheering.7．We haven't seen each other since we graduated from the university.8．Since/Now_that he has grown up, you should not tell him what he should do.9．It was because she caught a bad cold that she didn't go to school.10．He must have experienced something unpleasant, for he looks so sad.Ⅱ.完成句子1．Whenever_I_see_someone_in_need,_I will spare no effort to help him.每当见到有人需要帮助，我就会尽力去帮助他。

4．The_moment/As_soon_as/Immediately_the_children_heard_the“习惯于做某事”。

4．答案与解析：frightened考查形容词。

feel为系动词，其后应跟形容词作表语，此处主语为I，所以填frightened “害怕的”。

5．答案与解析：taking考查非谓语动词。

位于介词after之后，所以用动词-ing形式作介词宾语。

6．答案与解析：While/When考查状语从句。

分析句子结构可知，此处需用while或when引导的时间状语从句。

7．答案与解析：board考查固定短语。

on board“在飞机上”，为固定短语。

8．答案与解析：had happened考查动词的时态。

主句时态为一般过去时，从句动作发生在主句之前，所以是过去的过去，应用过去完成时。

9．答案与解析：After考查介词。

由句意可知此处表示“在……之后”，所以用after。

10．答案与解析：was found考查动词的时态和语态。

nothing 与find之间为被动关系，应用被动语态；由全文的时态可知，应用一般过去时的被动语态。

He might be more comfortable inside an exam room, but that's not where his patients are. O'Connell is one of a handful of doctors making house calls to the homeless in the city.O'Connell was studying at Harvard Medical School when his teacher suggested he take what was supposed to be a one-year position as the founding doctor of a new health-care program for Boston's homeless. That turned into a 33-year career (事业) at the Boston Health Care for the Homeless Program (BHCHP), one of the country's largest of its kind.“You realize, ‘You know what, I'm just a doctor. And what I cando is I can get to know you and ease your suffering，’” O'Connell said. “You could not find a more grateful (感恩的) population.”And his patients are grateful. “This man is unbelievable！” one said.O'Connell treats the homeless for just about everything, from stitches (缝针) for an arm to surgery (手术) for the soul. If patients can't be treated on the street, he find them a treatment bed at the organization's medical room, a place for patients who are to sick to be on the streets but not ill enough for a hospital stay.“Everything I had been taught to do [in medical school]— go fast, be efficient (效率高的) — was useless when you take care of homeless people，” O'Connell told Harvard Magazine. “When you see somebody outside, you get them a cup of coffee and sit with them. Sometimes it took six months or a year of offering a sandwich or coffee before someone would start to talk to you .But once they open their heart, they'll come to you anytime because they trust you.”When asked about how his life might have turned out had he become a highly paid hospital doctor, O' Connell, said, “I never think about it anymore.”Some things are more valuable than money. Just ask the man who gets everything from patients who have nothing material(物质的) to give.【语篇解读】本文是记叙文。
