Dont use words, expressions, or phrase

19、s known only to people with specific knowledge. 現(xiàn)在分詞的被動式作定語時表示的動作正在發(fā)生或是與謂語動詞所表示的動作同時發(fā)生。如：Listen !

36、句，獨立成分)二、分詞作狀語1分詞作狀語形式的選擇形式意義V + ing (doing)與句中主語構(gòu)成邏輯上的主謂關(guān)系，與句中謂語動詞同時發(fā)生，或基本上同時發(fā)生。having + V + ed(having done)與句中主語構(gòu)成邏輯上的主謂關(guān)系，先于謂語動詞發(fā)生。V + ed (done)與句中主語構(gòu)成邏輯上的動賓關(guān)系。being + V + ed(being done)與句中主語構(gòu)成邏輯上的動賓關(guān)系，且與謂語動詞同時發(fā)生，一般作原因狀語置于句首。having been + V +ed(having been done)與句中主語構(gòu)成邏輯上的動賓關(guān)系，且先于謂語動詞發(fā)生。2分詞作狀語的基本

37、原則分詞作狀語時，分詞的邏輯主語必須與句子的主語保持一致。分詞作狀語必須和句中主語含有邏輯上的主謂或動賓關(guān)系，否則不能使用分詞作狀語。3分詞作狀語的句法功能分詞或分詞短語作狀語時，可以表時間、原因、結(jié)果、條件、讓步、行為方式、伴隨狀況等。表示時間關(guān)系的分詞短語有時可由連詞while 或when 引出。如：Hearing the news, they got excited.

39、一般說來Frankly speaking 坦白地說Judging from 根據(jù)來判斷Considering 考慮到To tell you the truth 說實話清單六 非謂語動詞其它用法一、疑問詞 + 不定式結(jié)構(gòu)疑問詞（who, which, when, where, how, what等）+ 不定式，這個結(jié)構(gòu)在句中起名詞作用，可充當(dāng)主語、表語、賓語。如：高.考.資.源.網(wǎng)I didnt know what to do.

Why do sth. ?二、不定式的主動和被動1不定式修飾的名詞或代詞和不定式邏輯上構(gòu)成主謂關(guān)系時，不定式往往用主動形式。如：Do you have a knife to cut the watermelon ?(A knife cuts the watermelon.)2不定式和它前面被修飾的名詞或代詞構(gòu)成邏輯上的動賓關(guān)系，又和該句主語構(gòu)成邏輯上的主謂關(guān)系時，不定式常用主動形式。如：She has a sister to look after. (She looks after her sister.)I know w

41、hat to do. (I do what.)3不定式作表語形容詞的關(guān)語，和句中主語構(gòu)成邏輯上的動賓關(guān)系時，不定式多用主動形式，這是因為人們往往認(rèn)為形容詞后省去了for sb. 。如：This book is difficult to understand. This kind of fish is nice to eat. 4在there be 結(jié)構(gòu)中，當(dāng)說話人考慮的是必須有人去完成某件事時，不定式用主動形式；如果說話人強調(diào)的事情本身必須被完成，則用被動形式。如：There is a lot of work to do. (Someone has to do the work. )There

42、 is a lot of work to be done. (The work has to be done. )請注意下面兩個句子的含義的不同點：There is nothing to do. (無事可做，感到十分乏味。)There is nothing to be done. (某東西壞了，無法使之恢復(fù)正常。)三、不定式符號to 的保留問題有時為了避免重復(fù)，可以用to 來代替前面的不定式，這種情況出現(xiàn)在下列動詞之后：expect, hope, wish, mean, prefer, care, forget, want, try；或出現(xiàn)在be glad / happy, would lik

43、e / love 等的后面。如果在省略的不定式結(jié)構(gòu)中含有：be, have, have been，這些詞要保留。如：I havent been to Hong Kong, but I wish to. Are you on holiday ? No, but Id like to be. I didnt tell him the news. 我沒有告訴他那個消息。 Oh, you ought to have. 噢，你本應(yīng)該告訴他的。四、動名詞作主語動名詞或不定式都可以在句中作主語，但在下列句型中常用動名詞作主語。It is / was no use / good + doing sth. It

44、 is / was not any use / good + doing sth.It is / was of little use / good + doing sth. It is / was useless 如：It is no use crying over spilt milk. 覆水難收。It is of little good staying up too late every day. 每天都熬夜沒有什么好處若主語和表語都是非謂語動詞，應(yīng)保持形式上的一致。Seeing is believing. To see is to believe. 眼見為實。五、注意以下表達(dá)的意義區(qū)別f
