【知识要点】归纳when的用法

When的用法是近十多年来高考试卷中的 一个高频考点,既考查其在特定语境中的常 规意义, 也考查特殊意义 .

Ⅰ 1. when作从属连词引出状语从句,“当……时” ②He transplanted the little tree to the garden when it was the best time for it. ⑤The car helps to keep families together when it is used for picnics, outings and other shared experiences. ①(2009年重庆卷) Peter was so excited ____ he received an invitation from his friend to visit Chongqing. A. where B. that C. why D. when ②(2008年四川卷) There were some chairs left over _____ everyone had sat down. A. when B. until C. that D. where

注意:从句有时可简化为“when+现在分词/过去分词/形容词/名 词/介词短语”
( 1 ) 入乡随俗 When in Rome, do as Romans do. . ( 2 ) When (we are ) young, we are full of hope. 年轻时,我们大家总是充满希望。 standing ( 3 ) Don't reach sideways when __________ (stand)on a ladder. 站在梯子上时,不要侧着身子去够东西

asked ( 4 ) When __________(ask) about the possibility that Justin was taken by aliens.

2. 表示对比,“既然;本(应该、可以)……却(而) ……,” A. when后面的从句谓语动词常用虚拟语气。

引导让步状语从句,意为“虽然;然而;可是”,相当于although
⑧It was foolish of you to take a taxi when you could have easily walked there in five minutes.

( 1 ) She paid when she could have entered free. 本来可以免费入 场,而她却付了款。 might have succeeded ( 2 ) She stopped trying when she ______________________ next time. 她本来下次有可能获得成功,但她却不再尝试了。 ( 3 ) They were gossiping, when theyshould have been working _____________________. 他们本该工作,却在那里说别人的闲话。

B 可以作“既然,考虑到”解,引导原因状语从句,相当于since, now that, as或considering that

I can’t tell you anything when you won’t listen.
既然你不想听,我就什么也不告诉你了。

How could you, when you knew that this might damage it? 既然你知道这样会损害它,你怎么能这样做呢?

3. 表示条件,相当于 if ,引导条件状语从句。 但when作“如果;要是”解通常表示对某事是否会发生有把握 ,if 则表示对某事是否会发生没有把握 How can I get a job when I can't even read or write? 如果我连读和写都不会,我怎么能找到工作呢? How can you hope for mercy when you show none?

如果你不宽恕别人,你怎么能希望得到别人的宽恕呢?

比较:

Let me know when you need money. (I’m sure you’ll need money)
Let me know if you need money. (perhaps you’ll need money)

Don’t be afraid of asking for help ______ it is needed.(NMET2003 A. unless B. since C. although D. when

4. when表示“还没……就……” ”刚……就;一……就” ⑦I had hardly covered more than 30 miles in the snow when I found that the fuel was used up.

常见下列结构: Hardly/scarcely/barely had 主语 done when 主语 did 使用该句型时要注意: ① hardly 后的谓语动词用过去完成时 ,when后谓语动词要用过去时 ②hardly位于句首时, hardly 后的句子要倒装,而when引导的句子 不倒装。 ( 1 ) 我们刚刚入睡,铃声就响了起来 We had hardly fallen asleep when the bell rang. _____________________________________________________ Hardly had we fallen asleep when the bell rang. ( 2 ) He had scarcely arrived when he had to leave again. ______________________________________。 他刚刚到达就又要离开了。

When did you come here? 你什么时候来这里的? 译:———————————————— when you came here. I don't know__________________________ Ⅱ when引导的特殊疑问句调整成陈述句语序,在主句中不同 的位置做不同类别的名词性从句,通常翻译为在何时或在那时 ⑥His parent has been saving like crazy in the past five years for when he will go to university.
他什么时候回来很多取决于天气。 When she’ll be back depends much on the weather.

①(2009安徽卷) A good friend of mine from ____ I was born showed up at my home right before I left for Beijing. A. how B. whom C. when D. which
解析:考查when引导的宾语从句。句中“when I was born”作介词from的宾 语,修饰限定前面的a good friend of mine。句意为:在我动身去北京之前, 儿时的一个好友来到了我家。

②(2006 全国Ⅰ) Please remind me _____ he said he was going, I may be in time to see him off. A.where B. when C. how D. what
解析:考查when引导的宾语从句。When 在从句中作时间状语,句子意思为 :“提醒我他什么时候走,我好及时给他送行”。

When 引导疑问句有两种构成: (1)介词Since/Till +when+一般疑问句?(注:此时when作疑 问代词,作介词的宾语。); (2)when+一般疑问句?(注:when 作疑问副词,在特殊疑问 句中作状语。)。 (2007 陕西卷)-______ when has the country been open to international trade? - 1978, I suppose. A. Since B. In C. From D. After 解析:since 意为“自从”,常与现在完成时连用,表示动作从 某个时候开始,一直延续到现在。此题根据特殊疑问句中的时态 可判断用since,句意为:这个国家从什么时候起进行国际贸易的 ?

when 还可以接不定式 when to go sightseeing Have you decided ______________________(何时去观光)? When have you been here? How long have you been here? √ ☆when问的是具体时间,所以不能和完成时连用。 What time does the train leave? 强调具体是几点几分.可以与When混用. When will you graduate?

×

强调大体上的时间,此处不能用What time.
what time 指具体的时间的,而when 指 大体的时间

Ⅲ when引导定语从句,翻译为在那时 ①We are living in an age when many things are done on computer. (2009江苏卷) Because of the financial crisis, days are gone _____ local 5-star hotels charged 6, 000 yuan for one night. A. if B. when C. which D. since
注意:做这类题关键是将先行词还原看其在从句中所作的成分 that 1). Do you still remember the days ________ we spent in Qingdao? when 2). Do you still remember the days ________ we spent the summer holidays in Qingdao?

when引导定语从句代替的先行词在从句中作时间状语,但此时 定语从句之前的先行词不是time/day等明显的时间名词,而为隐 性的如:occasion, ages, period等。在这时when可以换为“介词 +which”结构。 ①(2008山东卷) Occasions are quite rare _____ I have the time to spend with my kids. A. who B. which C. why D. when ②(2008 上海卷)We went though a period _____ communications were very difficult in the rural areas. A. which B. whose C. in which D. with which

when可以引导非限定性定语从句。近年来常考:介词( since/from)+关系代词when引导的定语从句,其前常是时间状 语。注意:介词的宾语一般都由关系代词来充当,可是在 since, by, from等几个表示时间、或地点的介词后面习惯用when, where 或者which +名词作宾语。这种用法常见于非限制性定语从句中

①(2008 延考区)Jane is back in May, by____ the new house should be finished. A. which B. that C. whom D. when (2007山东卷) The book was written in 1946, ____ the education system has witnessed great changes. A. when B. during which C. since then D. since when

Ⅳ when连接并列句, 表示“就在那时”,相当于“and just at that time”
常见下列结构: was/were doing sth when… had done sth when… was/were about to do sth when… was/were on the point of doing sth when…

③Jas was holidaying with her family in a wildlife park when she was bitten on the leg by a lion.

④We were just on the point of calling you up when you came in.

Ⅰ Introducing an adverbial clause 1. when作从属连词引出状语从句,“当……时” 注意:从句有时可简化为“when+现在分词/过去分词/形容词/名 词/介词短语”
2. 表示对比,“既然;本(应该、可以)……却(而) ……,” A. when后面的从句谓语动词常用虚拟语气。

引导让步状语从句,意为“虽然;然而;可是”,相当于although

B 可以作“既然,考虑到”解,引导原因状语从句,相当于since, now that, as或considering that

3. 表示条件,相当于 if ,引导条件状语从句。 但when作“如果;要是”解通常表示对某事是否会发生有把握 ,if 则表示对某事是否会发生没有把握
4. when表示“还没……就……” ”刚……就;一……就” 常见下列结构: Hardly/scarcely/barely had 主语 done when 主语 did 使用该句型时要注意: ① hardly 后的谓语动词用过去完成时 ,when后谓语动词要用过去时 ②hardly位于句首时, hardly 后的句子要倒装,而when引导的句子 不倒装。

Ⅱ Introducing a noun clause
when引导的特殊疑问句调整成陈述句语序,在主句中不同的位 置做不同类别的名词性从句,通常翻译为在何时或在那时 When 引导疑问句有两种构成: (1)介词Since/Till +when+一般疑问句?(注:此时when作疑 问代词,作介词的宾语。); (2)when+一般疑问句?(注:when 作疑问副词,在特殊疑问 句中作状语。)。

Ⅲ Introducing an attributive clause when引导定语从句,翻译为在那时
