10、-ing形式與動(dòng)詞不定式在句中作狀語(yǔ)的區(qū)別。-ing形式在句作狀語(yǔ)表示時(shí)間、原因、方式或伴隨情況，而動(dòng)詞不定式一般式在句中作狀語(yǔ)時(shí)，一般是作目的或結(jié)果狀語(yǔ)，如：Not receiving his letter, I wrote to him again./ I looked into the window to see what was going on inside.

練習(xí)、非謂語(yǔ)動(dòng)詞(二)

9、-ing形式與動(dòng)詞不定式在作賓語(yǔ)補(bǔ)足語(yǔ)時(shí)的區(qū)別。(1)不定式作賓補(bǔ)時(shí)，其動(dòng)作一般發(fā)生在謂語(yǔ)動(dòng)詞所表示的動(dòng)作之后，如：I have told them to come again tomorrow.(2)在see, watch, hear, feel等之后，如果用-ing形式作賓補(bǔ)，表示其動(dòng)作正在進(jìn)行中，而用不帶to的不定式作賓補(bǔ)時(shí)，不定式所表示的動(dòng)作是一個(gè)動(dòng)作的過(guò)程，如：I hear her singing in the room.我聽(tīng)見(jiàn)她正在屋里唱歌。 I hear her sing in the room.我聽(tīng)見(jiàn)她在屋里唱過(guò)歌。

8、-ing形式與動(dòng)詞不定式在句中作定語(yǔ)的區(qū)別。-ing形式作定語(yǔ)用時(shí)，其動(dòng)作一般與句中謂語(yǔ)動(dòng)詞所表示的動(dòng)詞同時(shí)發(fā)生，而動(dòng)詞不定式作定語(yǔ)時(shí)，其動(dòng)作一般發(fā)生在句中謂語(yǔ)動(dòng)詞所表示的動(dòng)作之后。如：The girl writing a letter there can speak English very well./I have three letters to write.

7、-ing形式與動(dòng)詞不定式在句中作主語(yǔ)、表語(yǔ)、賓語(yǔ)時(shí)的區(qū)別。一般說(shuō)來(lái)，表示一個(gè)比較抽象或泛指的動(dòng)作時(shí)多用-ing形式。表示一個(gè)具體某一次的動(dòng)作時(shí)，多用動(dòng)詞不定式，如：Our job is making steel. She likes playing the piano, but she doesn't want to play it today.

6、-ing形式的復(fù)合結(jié)構(gòu)。在-ing前加物主代詞或名詞所有格即構(gòu)成-ing的復(fù)合結(jié)構(gòu)。其中的物主代詞或名詞所有格為-ing的邏輯主語(yǔ)。這種結(jié)構(gòu)在句中可作主語(yǔ)、賓語(yǔ)或表語(yǔ)，如：Your smoking and drinking too much will do harm to your health. 但在口語(yǔ)中，這種結(jié)構(gòu)如作賓語(yǔ)用，其中的物主代詞常用人稱代詞的賓格，名詞的所有格常用名詞的普通格代替，如：She insisted on Peter’s (or Peter)going there first.

4、被動(dòng)語(yǔ)態(tài)-ing一般式的基本用法。被動(dòng)語(yǔ)態(tài)-ing一般式所表示的動(dòng)作是一個(gè)正在進(jìn)行中的被動(dòng)動(dòng)作，而且這個(gè)被動(dòng)動(dòng)作也是和句中謂語(yǔ)所表示的動(dòng)作同時(shí)發(fā)生的。它一般在句中作定語(yǔ)或狀語(yǔ)用。如：The truck being repaired there is ours.

3、主動(dòng)語(yǔ)態(tài)-ing完成式的基本用法。主動(dòng)語(yǔ)態(tài)-ing完成式所表

詞所表示的動(dòng)作之前，一般在句中作時(shí)間或原因狀語(yǔ)用。句中的主語(yǔ)是它的邏輯主語(yǔ)，并且是它所表示的動(dòng)作的執(zhí)行者，如：Having answered the letter, she went on to read an English novel.
