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.(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) 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. 五.訓(xùn)練評(píng)價(jià) 根據(jù)提示完成單詞。 1. We should put up notice to stop from l________。 2.
