—She wondered ________we could complete the experiment. A．when was it B．it was when that C．it was when D．when it was that 【特别提醒】 强调句型
1．强调句的基本句型是“It is/was＋被强调的部分＋that/who＋其他部分”。被强调的部分可以是主语、宾语和状语等。
It is only children who make such stupid mistakes. 只有孩子才会犯这样愚蠢的错误。
2．强调句型的一般疑问句只需将is/was提前，特殊疑问句的结构是“疑问词＋is/was＋it＋that从句”。 What is it that you want me to do? 你要我干什么？
3．如果原句中含有“not...until”，在强调时间状语时，将主句中的否定词not连同状语一起提前。 It was not until she took off her dark glasses that I realized she was a famous film star. 直到她摘下墨镜，我才认出她是一位著名的电影明星。
4．强调句型结构与名词性从句、定语从句、状语从句的混合使用
在高考试题中，为了增加试题的难度，命题人常常将强调句型与定语从句、状语从句等混合起来，使句子结构更加复杂。考生要注意从语法角度分析句子，理清“强调句型与定语从句”。
※①当我们看到“It be...＋从句”结构时，首先考虑是否为强调句式，方法就是去掉it be与that/who后，看剩下的部分是否完整。
②若不是强调句式，那么推测是否为主语从句，即it是否指代后面的从句，可以用替换法尝试。 ③当be后为一段时间时，不要忘了It be...since/before结构。 例4、There is little doubt in your mind that he is innocent, ________？ A．is there B．isn't there C．is he D．isn't he 【举一反三】
①I told them not everybody could run as fast as you did, ________？

A．could he B．didn't I C．didn't you D．could they
②I'm sure you'd rather she went to school by bus, ________？ A．hadn't you B．wouldn't you C．aren't I D．didn't she
③It's the first time that he has been to Australia, ________？ A．isn't he B．hasn't he C．isn't it D．hasn't it
④She must have finished the work the day before yesterday, ________？ A．mustn't she B．does she C．didn't she D．hasn't she 【特别提醒】
1．如果反意疑问句的前一部分为肯定形式，则反意疑问部分用否定形式；反之，如果前一部分是否定形式，后一部分就要用肯定形式。
当陈述部分含有seldom, hardly, never, scarcely, few, little, nothing, nobody等否定词或半否定词时，疑问部分的动词用肯定式。
The old woman could hardly write her own name, could she? 那位老太太几乎不会写自己的名字，是吗？ She said I did it, didn't she？她说是我干的，是吗？
2．当主语是第一人称单数，谓语动词是think, believe, suppose, imagine, expect, guess，be sure等词时，要注意否定转移，而且反意疑问部分要与从句保持一致；如果主语是其他人称，反意疑问部分与主语保持一致。
I don't think you can solve the problem in two minutes, can you？我们认为你在两分钟之内不能解决这个问题，你能吗？(反意疑问部分与从句一致)
3．陈述部分含有must等表推测的情态动词的反意疑问句。
must等表示推测，疑问部分不能用must等情态动词，而应根据must后的动词结构采用相应的动词形式。
他昨天一定离开了，是吗？
He must have left yesterday, didn't he？(有明确过去时间状语) He must have left, hasn't he？(无明确过去时间状语)

例5、When you are done with the book, just give it to Lucy or Helen or ________． A．whoever B．wherever C．whatever D．however 【举一反三】

A．want to B．want to be C．want so D．want it
④Although ________considerable success as an artist, the young man keeps working hard. A．achieving B．achieved C．to achieve D．having achieved 【特别提醒】 省 略
1．在when, while, whenever, till, as soon as, if, unless, as if, though, as等引导的状语从句中，若谓语部分含有be动词，而主语又与主句主语相同或主语是it时，从句的主语和be动词常被省略。
The experiment shows that proper amounts of exercise, if carried out regularly, can improve our health. 实验表明，如果有规律地进行适量运动能强身健体。
2．I'm afraid, I think, I believe, I hope, I guess等作答句，后面跟so与not分别等于肯定或否定，宾语从句可省去。
—Do you think it will rain？——你认为会下雨吗？ —I hope not(that it will not rain)．——我希望不下。 —Do you believe our team will win? ——你相信我们队会赢吗？ —I guess so.——我猜会赢。
3．不定式省略，单独使用不定式符号to。
8
(1)用来代替动词不定式后被省略的动词，常在be afraid, glad, happy, expect, forget, hope, intend, like, love, mean, prefer, refuse, seem, try, want, wish等的后边。
I asked him to see the film, but he didn't want to. 我请他去看电影，但他不想去。
—Will you join in the game？——你愿意加入做游戏吗？ —I'd be glad to.——我很高兴加入。
(2)如果不定式中含有be, have, have been，通常保留be, have和have been。 —Are you a sailor？——你是海员吗？ —No, but I used to be.——不，但我过去是。 【易错点点睛】
易错点点睛 1 强调句的正确运用
1. It wasn’t until nearly a month later __ I received the manager’s reply. A. since B. when C. as D. that 2. It was __ back home after the experiment. A. not until midnight did he go B. until midnight did he go C. not until midnight that he went D. until midnight when he didn’t go
3. It was in the classroom __ was built by the local government they finished their homework. A. where; that B. that; that C. that ;where D. where; where
5. It was on september 1 st he became a member of our school. A. when B. that C. / D. till 【特别提醒】
使用强调句时，应该注意如下几点:
1.强调状语:It is tomorrow that will hold the meeting.(that不能换成when)
9
It was on the sports ground that I found (that 不能换成where)
2.强调含有not...util...一结构的句子时，要用 It is／was not until...that...结构。that后的句子要 用肯定句，且须用陈述语序。
3.强调句和主语从句句型(指 “It+be+adj.／n.+that从句”类型)的异同点:二者均有 It be ... that／who...之类的语言标志。所不同的是:
(1)含有主语从句的句子译为汉语时不可加上“正是……”或“就是……”之类的字眼，而强调则可以。 (2)含有主语从句的句子若删掉 It be...that／who...则原句不论结构还是语意均不成立，而强调句去掉结构标志仍然成立。如:It is ture that he once went to to Canada.(不可以去掉 It is及that，否则原句不成立)
It was on December 11，典型例题at China became a member of WTO.(去掉was及that后原句仍然成立)
4.含有定语从句的强调句型:仔细分析出at或 who在句中的作用，若that或who可有可无(结合it be来分析)，则为强调句，否则是定语从句。如:
It was in the lab that was set up by Mr.Smith that they finshed the experiment.(lab后的出at不可省略,因为出at引导定语从句，作该句的主语。句中第二个，that才是强调句的标志。)
5.强调谓语时用“do/does／did+动词原形”。如: He did come yesterday.他昨天的确来了。 【举一反三】
1 It is these poisonous products __ can cause the symtoms of the flu, such as headache and aching muscles.
A. who B. that C. how D. what 2 It was not long __ he was born __ his mother died.
A. before; that B. since; when C. until; when D. after; that
3 It must be he that has stolen Mr. Smiths purse, ? A. hash’t he B. isn’t he C. mush’t it D. isn’t it
4 I have always been honest and straight forward, and it doesn’t matter __ I’m talking to. A. who is it B. who it is C. it is who D. it is whom
