If they like to, they can have a quiz. 備課資料 動(dòng)詞不定式作目的狀語的用法 英語中的動(dòng)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(dòng)詞不定式作目的狀語進(jìn)行單獨(dú)討論。 一、

28、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(dòng)詞，表示某一動(dòng)作或狀態(tài)的目的。為了使目的意義更加清楚或表示強(qiáng)調(diào)意義時(shí)，還可以在前面加 in order to 或 so as to。例如: I’ve 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(dòng)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

29、. (正) To draw maps properly, a special pen is needed. (誤) 由 in order to 引導(dǎo)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(dǎo)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)

30、 So as to get there in time, they started early. (誤) 二、不定式的復(fù)合結(jié)構(gòu)作目的狀語 當(dāng)不定式或不定式短語有自己的執(zhí)行者時(shí)，要用不定式的復(fù)合結(jié)構(gòu)(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, s

31、o that, in order that, lest, for fear that, in case等詞引導(dǎo)，例如: You must speak louder 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(jié)果狀語從句 結(jié)果狀語從句常由so. . . that或such. . . that

32、引導(dǎo)，掌握這兩個(gè)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，little連用，形成固定搭配。 so nice a flower　　　　　　　　such a nice flower so many/few flowers such nice flowers so much/little money such rapid progress so many people such a lot of people so. . . that與s

33、uch. . . 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 can’t go to school. He is such a young boy that he can’t go to school 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(jié)構(gòu)上得以簡(jiǎn)化?？煞譃閮煞N情況: 1. 當(dāng)目的狀語從句中的主語與主句中的主語相同時(shí)，可以直接簡(jiǎn)化為不定式或不定式短語作狀語。例如: We’ll start early in order that/so that we m

34、ay arrive in time. We’ll start early in order to/so as to arrive in time. 2. 當(dāng)目的狀語從句中的主語與主句中的主語不相同時(shí)，要用動(dòng)詞不定式的復(fù)合結(jié)構(gòu)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(duì)大家有所幫助，多謝您的瀏覽！
