【正文】 。 特殊句式中也表同時進(jìn)行,但必許用to do. 如:happen to do,seem to do (2)不定式的時態(tài)要與不定式前的動詞對比,是在之前?后?還是同時或正在進(jìn)行。 He would like to have played the violin at the concert. 沒演奏成。 We planned to have done good deeds for the poor people last month. 沒做成。一般式被動 It’s an honour for me to be invited.(與句子謂語同時發(fā)生) (這里為什么不用to invite,因為to invite不是修飾me的,不是定語,而是真正主語) (二)不定式的正在進(jìn)行時,表前一個動作發(fā)生時,不定式所表動作正在發(fā)生Some dogs were found to be looking for food around. 一些狗被發(fā)現(xiàn)正在四處尋找食物。不定式的時態(tài)、語態(tài)不定式都表發(fā)生在過去或現(xiàn)在的將來、目的或結(jié)果,有各種時態(tài)和語態(tài) 一般式 to do /to be done 完成式 to have done /to have been done 進(jìn)行式 to be doing 完成進(jìn)行式 to have been doing(根據(jù)語境來判斷該用何種時態(tài)和語態(tài))(一)一般式表示動作通常與句子謂語所表示的動作或狀態(tài)幾乎同時發(fā)生,或是在它之后發(fā)生。 No, I tried to, but failed. 沒有。(2) –Did you find the reference books about it? 你找到有關(guān)的參考書了嗎?注意:為了避免重復(fù),動詞不定式中與上文相同部分可以省略掉,但to須保持下來。4. would rather后接動詞原形。2. 感官動詞see/ hear/ watch/ notice等和使役動詞make/ have/ let等后接動詞原形做賓補(bǔ)。This question was too difficult for everybody in our class to answer.這個問題太難了,我們班的所有人都回答不上來。The little boy doesn’t study English well enough to understand you.這個小男孩英語學(xué)得不好,他不懂你的意思。6. 不定式的 “(not)+形容詞或副詞+enough to”結(jié)構(gòu)和 “(not)+形容詞或副詞+enough for sb/ sth to do.”“……能夠做某事”或“……不能做某事”。too…for…to結(jié)構(gòu)連接兩個單句中主語不相同的句子。(1) too…to結(jié)構(gòu)和too…for…to結(jié)構(gòu)連接句子的區(qū)別:too…to結(jié)構(gòu)連接兩個單句中主語相同的句子。She is too young to go to school. 她太小不能上學(xué)。(4) 作賓語補(bǔ)足語She often teaches me how to read and write. 她常教我如何讀書寫字。注意:帶特殊疑問句的不定式可跟帶特殊疑問詞的賓語從句進(jìn)行句型轉(zhuǎn)換。(3)(2)4. 不定式的“疑問詞+不定式”結(jié)構(gòu)此結(jié)構(gòu)在句中的語法作用有以下幾點:(1)It was careless of him to lose so many things. 他丟了這么多東西,真是太粗心了。3. 不定式的 “of+名(代)+不定式”結(jié)構(gòu)It is very nice of you to help me. 你來幫我真是太好了。It is very important for you to practise your oral English in the daily life.在日常生活中練習(xí)你的英語口語是非常重要的。I asked him not to e here. 我請他不要來。不定式否定句沒有助動詞,否定句有助動詞。She asked the old man not to be angry. 她請這位老人別生氣。3. 表原因I am sorry to hear that. 聽到這件事,我感到很難過。2. 表結(jié)果What has he said to make you so sad? 他說了什么話讓你這樣傷心?They lifted a rock only to drop in on their own feet. 他們搬起石頭砸了自己的腳。In order to study English well, she often does more speaking and writing.
