　　除非被邀请，否则我不 去参加的生日晚会。 句型15 when引导的从句 when除了用来引导主语从句、宾语从句、时间状语从句、表语从句和定语从句，还有一种用法值得关注，那就是when引导并列分句，意思是“这时突然；就在那时”，强调另一个动作的突然发生。常用于以下句型中： （1）、主语 + be doing… when…意思是“正在做某事这时……”； （2）、主语 + be about to do…when…； （3）、主语+be on the point of (doing) …when…意思是“正要去做某事这时……” [例句] One day Chuck was on a flight across the Pacific Ocean when suddenly his plane crashed. 有一天，Chuck正在太平洋上飞行，这时他的飞机突然爆炸了。 I don’t know when he will arrive. 我不晓得他什么时候到达。 I thought of the happy days when I was in Beijing. 我想起了在北京时的那段快乐日子。 I believe the time will soon come when there will be no weapons in the world. 我相信世界上没有武器的日子不久就会到来。

　　句型16 while引导的从句 while除了有“当/在……时候”的意思外（注意：引导的句子谓语动词只能是延续性动词！），另外的两层意思也是考查的重点：（1）while = although “尽管”、“虽然”，引导让步状语从句；（2）while的意思是“然而；可是”，常用来表达对比关系。 [例句] While I admit that the problem is difficult, I don’t think that they can’t be solved. 尽管我承认这个问题很难，但是我并不认为无法解决。 While I admit his good points, I can see his shortcomings. 虽然我承认他的优点，我也能看出他的缺点。 While I was angry with her, I didn’t lose my temper. 虽然我很生气，但我当时没有对她发脾气。 While I understand your viewpoint, I don’t agree with you. 虽然我了解你的见解， 我还是不能同意（你）。 I earn only 120 dollars a week, while she earns 180 dollars. 我一星期只赚120美元，她却赚180美元。 where…（地点从句） [注意]where引导地点从句时，可以引导定语从句或是逻辑地点状语从句。当它在定语从句中作地点状语，指代地点时，这时可以用in which, on which, at which, to which, from which等结构代替。但是它引导逻辑地点状语从句时，没有这样用法。 [例句] You should put the book where it was. 把书放回原处。 Persistent people begin their success where others end in failure. 不屈不挠者从他人失败的地方获取成功。 Where there is a will, there is a way. 有志者，事竟成。 Where men are greedy, there is never peace. 人类贪欲不止，世界和平无望。 Go where you should, keep on studying. 无论你到哪里，你都应该继续学习。 That is the building where my father works. 那是我父亲工作的大楼。 Yesterday I went to the department store, where I met my teacher. 昨天我去百货公司，就在那儿遇见了我的老师。 That’s where a change is needed. 那就是需要变更的地方。 We could see the runners very well from where we stood. 从我们所站的地方能很清楚地看到赛跑的选手。 You should let your children play where you can see them. 你应该让小孩在你的视线所及的地方玩耍。 Potatoes can be grown in places where it is too cold to grow rice.=Potatoes can be grown in places where it is too cold to grow rice.（本句where引导定语从句） 有些地方太冷不能种水稻，但可以种马铃薯。 [请比较下面的句子结构的不同] Potatoes can be grown where it is too cold to grow rice.（本句where引导地点状语从句） 句型18 what引导的从句 what在英语中非常活跃,它可以用来引导主语从句、宾语从句、表语从句，但是不用来引导定语从句。在句子里可以充当主语、宾语、表语、定语，既可以指人，也可以指物。 What is the population of the world? 世界的人口有多少？ What did you pay for this picture? 这幅画你付了多少钱？ What is most important in life isn’t money. 人生最重要的并非是金钱。 Will you show me what you bought? 可以把你所买的东西给我看一下吗？ Mary is no longer what she was ten years ago. Mary已经不是10年前的她了。

　　句型19 as引导的非限制性定语从句

　　在as引导的非限制性定语从句中，连接代词as在句子中可以作主语、宾语或表语等，可以指人或物。其在定语从句中的位置比较灵活，即可以在句子前面，在句子中间或句子末尾。常用的结构有：as we all know; as is well known to…; as is often the case; as is said/mentioned above; as has been said before; as I told you before; as is evident; as often happens; as can be seen; as is/was expected; as we expect; as I can remember等。 [注意1]as通常只指整个句子的内容，不表示部分内容。 [注意2]as引导的非限制性定语从句通常指“事先可以预料到的”“料想到的”，表达“好”的方面。 [注意3]as引导限制性定语从句时，常构成the same…as…; such…as…; so/as …as…等结构。在从句中既可以指人、物，也可以指整个句子。 [例句] This is also part of your work, as I told you before. 我曾告诉过你，这也是你工作的一部分。 The man was a teacher, as was evident from his way of speaking. 从那人说话的样子可明显看出，他是个老师。 Such ideas as he hits on are worthless. 像他那样偶然想起的主意是无用的。 It’s the same story as I heard from her yesterday. 这故事跟我从她那儿听到的相同。 He will marry as pretty a girl as he can find. 他要尽可能找漂亮的女孩结婚。 Such people as have made great contributions to the world should be greatly respected. 那些对世界做出巨大贡献的人们应该受到极大的尊重。 句型20 which引导的非限制性定语从句（也引导限制性定语从句）

　　which引导的非限制性定语从句既可以指整个句子内容，也可以指句子的部分内容（如单词或词组等），在句子中可以作主语、宾语（动词或介词的）、定语等。注意它在句子中的位置：只能放在主句后，不能放在主句前。表达的内容是“不好的”、“事先没有预料到的”等时，常用which，只指物。 [例句] Yellowstone National Park, which is in Wyoming, is one of the most beautiful national parks in the world. 黄石国家公园位于怀俄明州，是世界上最美丽的国家公园之一。 The clock, which my grandfather bought, is still in good order. 这时钟是我祖父买的，现在还走时很准。 The picture, for which he paid an enormous amount of money, was a forgery. 那幅画他花了一大笔钱购买，却是幅赝品。 She changed her mind again, which made us all angry. 她又改变了主意，这使我们大家都生气了。 I lived three years in Paris, during which time I learned French. 我在巴黎住了三年，在那期间我学了法语。 The weather turned out to be very good, which was more than we could expect. 天气结果转晴， 这是我们没有预料到的。 句型21 （1）、疑问词+ever

　　whatever, whoever, whichever, whenever, wherever, however用来引导让步状语从句，相当于no matter和what, who, which, when, where, how连用

　　[例句] Whatever (=No matter what) may happen, we shall not lose hope. 无论发生什么事，我们都不能失去希望。 Whatever reasons you (may) have, you should carry out a promise. 无论你有什么理由，你都应该遵守诺言。 Whoever (=No matter who) comes, he will be warmly welcome. 无论谁来，都会受到热烈欢迎。 Whenever (=No matter when) it happened, it was certainly not yesterday. 此事无论发生在何时，但绝不是昨天。{{{ Whenever you (may) call, you will find her sitting by the window. 无论什么时候你去找她，你都会看到她坐在窗边。 Wherever (=No matter where) he went, he made friends with people. Whichever (=No matter which) of them you many choose, the quality will be the same. 他们当中不论你选哪一个，品质都一样。 However (=No matter how) hard I have tried, I can’t find the answer.

　　（2）、whatever, whoever, whichever, whomever等引导名词性从句，这时不能用no matter+疑问词替换。 [例句] Take whichever you want. 你要哪个就拿哪个。 We will do whatever we can to help him out. 我们要尽力帮助他摆脱困境。 I’ll show you whatever you want to see. 你想看什么我就给你看什么。 Whoever did this job must be rewarded. 无论谁做这件事都要得到报酬。 Whoever walks around in such a heavy rain will catch a cold. 任何人在这种大雨中行走都会患感冒。 You may invite whomever（口语中常用whoever代替）you like to the party. 你可以邀请你喜欢的人来参加晚会。 Take whatever magazines you want to read. 你可以取阅任何你想读的杂志。 句型22

　　It is necessary/important/natural/impossible/essential（基本的）等结构后的主语从句中要用虚拟语气，即主语+(should)+动词原形 [例句] It’s necessary that Tom take the exam first. Tom有必要先参加考试。 With the society developing very fast, it’s quite necessary/important that we (should) have a good knowledge of English and computer. 随着社会的快速发展，我们有必要精通英语和电脑。 句型23 It’s strange/surprising/a pity/a shame/a surprise (that) … should do…should表示“竟然” [例句] It’s a pity that she should miss the chance. 很遗憾她错过了机会。 It’s really surprising that a prophecy（预言）should coincide with the fact so exactly. 令人惊讶的是，预言和事实竟然如此巧合。 It’s strange that he shouldn’t pass the exam. 奇怪的是他竟然没有通过考试。

　　特殊句式

　　辨别句子结构是考生应对高考应具备的能力之一。英语中句子结构很多，也很容易混淆。特殊句式内容比较杂乱，掌握起来有一定的难度。其中倒装句是高考的热点，强调句是高考的难点。同时，祈使句与陈述句的区别、省略与替代的合理运用等是高考考查的重点项目。预计2016年高考会继续侧重对倒装句和强调句的考查，所以对于这些热点考生要真正地把握，理解其精髓。 考点全解 　考点一　强调句 　 【情系考场】　 1．(2010年安徽卷)It was from only a few supplies that she had bought in the village________the hostess cooked such a nice dinner. A．where　B．that C．when

　　D．which 答案：B 【情系考场】　 2．(2010年四川卷)If you have a job，________yourself to it and finally you'll succeed.

　　A．do devote

　　B．don't devote C．devoting

　　D．not devoting

　　考点二　反意疑问句 高考对反意疑问句的考查以考查反意疑问部分的变化为主，主要集中在以下四个方面： 1．考查对含有情态动词的句子的反意疑问。这些情态动词主要有would，must，would rather，used to，ought to，had better等。 2．考查对含有易混动词的句子的反意疑问。比如have既可以是助动词，也可以是实义动词；need，dare既可以是情态动词，也可以是实义动词。 3．考查对祈使句的反意疑问。当主句为祈使句时，反意疑问部分用will you。而由let's构成的祈使句，反意疑问部分则用shall we。祈使句的形式多样，大家要注意辨别。 4．考查对there be句型的反意疑问。 【情系考场】 3．They must have gone to the cinema last night，________？ A．didn't they

　　B．don't they C．mustn't they

　　D．haven't they 解析：此处must have gone是表示对过去情况的推测，而且是肯定的推测，因此后面用didn't构成反意疑问部分。 答案：A 【情系考场】 4．Sarah had her washing machine repaired the day before yesterday，________she? A．had

　　B．did C．hadn't

　　D．didn't 解析：在have sth.done中，have是实义动词，而且前面是肯定句，因此后面用助动词的否定式didn't构成反意疑问部分。句意：萨拉前天请人修了洗衣机，是吗？ 　 　 5．When you've finished with that book，don't forget to put it back on the shelf，________？ A．do you

　　B．don't you C．will you

　　D．won't you 　 【情系考场】　 6．There was a loud scream from the backstage immediately

　　在2002年全国高校英语专业四级考试试题中,有以下一选择题: Fool——Jane is,she could not have donesuch a thing。 A.who B.as C.that D.1ike 所给的答案为B。请问选C不对吗? 此题设计不够严密。因为除了可以选B(as)外,还可以选C(that)。thm也可引导让步状语从句。例如: 1.Difficult that the task was.they managedto accompfish it in time.虽然任务很艰难,但他们正是设法如期完成了。(陆谷孙主编, ((英汉大词典》,缩印本,p.1958) 2.Newcomer that he is,he knows whm’S thefight thing to do.尽管他是个新手,他却知道该做些什么。(《英华大词典》最新修订版,p.1597) 3.Poor that they were,they gave money tocharity.尽管他们很穷,但他们还是把钱捐给了慈善事业。
