語法復習十二：非謂語動詞1動詞不定式
動詞不定式、分詞(現在分詞，過去分詞)和動名詞統稱為非謂語動詞。現代英語將現在分詞和動名詞合為一大類叫作v + ing形式。這些動詞的形式不能在句中單獨作謂語用，因而沒有語法主語。但可以有邏輯主語。由于沒有語法主語，也就不受人稱和數的限定，因為不是謂語，也就沒有時態和語態，但這些詞仍能表示動作和狀態，所以仍有表示與其他動詞相對時間關系的形式。由于與其它詞有邏輯上的主謂關系，因此也有表示主、被動的形式，同時也有自己的賓語和狀語，一起構成非謂語動詞的短語(動詞不定式短語，分詞短語，動名詞短語)。非謂語動詞在英語語法中占有特殊且重要的位置。非謂語動詞形式多樣，應用廣泛，且在句中起著很活躍的作用，也是語法項目中的重點和難點，學好非謂語動詞，才能正確進行口語和書面的交流。
動詞不定式、過去分詞及v-ing形式在句中均不能作謂語用，所以叫做非謂語動詞。
（一）動詞不定式：
動詞不定式由to+ 動詞原形構成，如：to study, to play，動詞不定式雖然不能作謂語動詞用，但仍留著動詞的特征，它可以帶有所需要的賓語或狀語而構成動詞不定式短語，如：to study hard, to play table tennis。
1、動詞不定式的形式變化：動詞不定式有下列時態和語態的形式變化。
語態式 一般式 完成式 進行式 完成進行式
主 動 to build to have built to be building to have been building
被 動 to be build to have been build
2、動詞不定式的基本用法：動詞不定式能起名詞、形容詞和副詞的作用，可在句中作主語、表語、賓語補足語、定語和狀語用，如：
（1）作主語：To help each other is good.（動詞不定式作主語時，一般可用it作形式主語，而將作主語的動詞不定式置于句末，如：It is good to help each other.
（2）作表語：My job is to drive them to the power station every day. 動詞不定式在系動詞be之后作表語，與表示將來時的be + 動詞不定式結構有所區別，如：Our plan is to set up another middle school for the peasants children.我們的計劃是給農民子弟再成立一所中學。（句中的謂語動詞為is，動詞不定式to set up 為表語，主語為plan，但plan并不是動詞不定式的邏輯主語，即動詞不定式 to set up所表示的動作不是主語plan產生的。）We are to set up another middle school for the peasants children.我們將為農民的子弟再成立一所中學。（句中的are to set up整個結構為句中謂語，主語為we，同時也是動詞不定式to set up所表示的動作的邏輯主語，即動詞不定式to set up所表示的動作是由we產生的）。
（3）作賓語：①作及物動詞的賓語，如：She wishes to be a musician.；②作某些形容詞的賓語：可以有動詞不定式為賓語的形容詞一般有glad, sorry, afraid, pleased, determined, willing, eager, anxious, ready, sure等，如：I am determined to give up smoking.；③動詞不定式一般不作介詞的賓語，但動詞不定式之前如有疑問詞時，就可作介詞的賓語，如：Can you give us some advice on what to do next?
（4）作賓語補足語，如：Tell the children not to play on the street. 如果句中的謂語動詞為see, hear, watch, notice, have, make, let等，作賓語補足語的動詞不定式須將to省去，如：I saw a little girl run across the street.
（5）動詞不定式在句中作賓語，如帶有賓語補足語時，須先用it作形式賓語，而將該動詞不定式后置，如：I dont think it right to do it that way.
（6）作定語：動詞不定式作定語時，須位于被其修飾的名詞或代詞之后，如：Is this the best way to help him? 和定語用的動詞不定式如果是不及物動詞，不定式后面就要用必要的介詞，如：He is the man to depend on. 如果被不定式修飾的名詞為place, time, way，不定式后面的介詞，習慣上可以省去，如：The old man is looking for a quiet place to live.
（7）作狀語：動詞不定式可以作下列的狀語：①目的狀語： Every morning he gets up very early to read English. 為了強調不定式表示目的的作用，可在不定式前加in order to或so as to（以便或為了），但應注意in order to位于句首或句中均可，而so as to不能位于句首，如：She reads China Daily every day in order to (so as to) improve her English. 將表示目的的不定式置于句首，也可強調目的的作用，如：To master a foreign language, one must work hard at it. ②結果狀語：They lived to see the liberation of their home town.他們活到親眼見到了他們家鄉的解放。③too + 形容詞或副詞 + 動詞不定式，表示足能的結果，如：You are old enough to take care of yourself now.
3、復合結構不定式：由for + 名詞（或代詞賓格）+ 動詞不定式即構成復合結構的動詞不定式。其中for本身無意義。for后面的名詞或代詞是不定式的邏輯主語，這種不定式在句中可作主語、表語、賓語、定語或狀語，如：It is very important for us to get everything ready for the harvest. 當作表語用的形容詞表示不定式的邏輯主語的性質或特征時，就用介詞of而不用for引出不定式的邏輯主語，這些形容詞一般有good, nice, kind, wise, silly, stupid, foolish, right, wrong, careless, impolite等，如：It is very kind of you to help him every day.
4、疑問詞 + 動詞不定式：疑問代詞和疑問副詞后可加動詞不定式構成不定式短語，在句中可作主語、表語或賓語，如：How to prevent them from swimming in this river is a problem.
5、動詞不定式的否定式：動詞不定式的否定式是由not + 動詞不定式構成，如：Its wrong of you not to attend the meeting.
6、動詞不定式的時態形式所表示的時間關系：（1）一般式：動詞不定式一般式所表示的動作是和謂語動詞所表示的動作同時發生，但在多數情況下，是在謂語動詞所表示的動作之后發生，如：We decided to plant more trees this spring.（其后），They often watch us play table tennis.（同時）；（2）完成式：動詞不定式完成式所表示的動作發生在謂語動詞所表示的動作之前，如：I am sorryto have kept you waiting.（3）進行式：動詞不定式進行式所表示的動作正在進行中，而且與謂語動詞所表示的動作同時發生，如：She happened to be writing a letter in the room when I came in.
7、動詞不定式的被動語態用法：如果動詞不定式的邏輯主語為這個不定式所表示的動作的承受者時，不定式一般就用被動語態形式，如：What is to be done next hasnt been decided yet.
