If they like to, they can have a quiz. 備課資料動詞不定式作目的狀語的用法英語中的動詞不定式具有副詞的功能，可以在句子中作狀語，表示多種意義。在這里就動詞不定式作目的狀語進行單獨討論。一、不定式和不定式短語作目的狀語不定式和不定式短語作目的狀語，主要用來修飾動詞，表示某一動作或

26、狀態(tài)的目的。為了使目的意義更加清楚或表示強調(diào)意義時，還可以在前面加 in order to 或 so as to。例如: Ive written it down in order not to forget.He shouted and waved so as to be noticed.在句子中作謂語動詞的狀語的不定式或不定式短語，表示的是主語的目的，因此，其邏輯主語通常是句子的主語。比較: To draw maps properly, you need a special pen. (正)To draw maps properly, a special pen is needed. (誤)

27、由 in order to 引導的目的狀語，既可以置于句尾，也可以置于句首，而由 so as to 引導的目的狀語，只能置于句尾，而不能置于句首。比較: They started early in order to get there in time. (正)In order to get there in time, they started early. (正)They started early so as to get there in time. (正)So as to get there in time, they started early. (誤)二、不定式的復合結構作目的狀語

28、當不定式或不定式短語有自己的執(zhí)行者時，要用不定式的復合結構(即在不定式或不定式短語之前加 for + 名詞或賓格代詞)作狀語。例如: He opened the door for the children to come in.She fetched several bottles which she placed on the counter for Harry to inspect.目的狀語從句表示目的狀語的從句可以由that, so that, in order that, lest, for fear that, in case等詞引導，例如: You must speak loude

29、r so that/in order that you can be heard by all.He wrote the name down for fear that(lest)he should forget it.Better take more clothes in case the weather is cold.結果狀語從句結果狀語從句常由so. . . that或such. . . that引導，掌握這兩個句型，首先要了解so和such與其后的詞的搭配規(guī)律。such是形容詞，修飾名詞或名詞詞組，so是副詞，只能修飾形容詞或副詞。so還可與表示數(shù)量的形容詞many，few，much

30、，little連用，形成固定搭配。so nice a flowersuch a nice flowerso many/few flowerssuch nice flowersso much/little moneysuch rapid progressso many peoplesuch a lot of peopleso. . . that與such. . . that之間的轉(zhuǎn)換既為 so與such之間的轉(zhuǎn)換。The boy is so young that he cant go to school.He is such a young boy that he cant go to scho

31、ol目的狀語從句與不定式的轉(zhuǎn)換英語中的目的狀語從句，還可以變?yōu)椴欢ㄊ交虿欢ㄊ蕉陶Z作狀語，從而使句子在結構上得以簡化?？煞譃閮煞N情況: 1. 當目的狀語從句中的主語與主句中的主語相同時，可以直接簡化為不定式或不定式短語作狀語。例如: Well start early in order that/so that we may arrive in time.Well start early in order to/so as to arrive in time.2. 當目的狀語從句中的主語與主句中的主語不相同時，要用動詞不定式的復合結構作狀語。例如: I came early in order that you might read my report before the meeting.I came early (in order)for you to read my report before the meeting. 希望對大家有所幫助，多謝您的瀏覽！
