10、-ing形式与动词不定式在句中作状语的区别。-ing形式在句作状语表示时间、原因、方式或伴随情况，而动词不定式一般式在句中作状语时，一般是作目的或结果状语，如：Not receiving his letter, I wrote to him again./ I looked into the window to see what was going on inside.

练习、非谓语动词(二)

9、-ing形式与动词不定式在作宾语补足语时的区别。(1)不定式作宾补时，其动作一般发生在谓语动词所表示的动作之后，如：I have told them to come again tomorrow.(2)在see, watch, hear, feel等之后，如果用-ing形式作宾补，表示其动作正在进行中，而用不带to的不定式作宾补时，不定式所表示的动作是一个动作的过程，如：I hear her singing in the room.我听见她正在屋里唱歌。 I hear her sing in the room.我听见她在屋里唱过歌。

8、-ing形式与动词不定式在句中作定语的区别。-ing形式作定语用时，其动作一般与句中谓语动词所表示的动词同时发生，而动词不定式作定语时，其动作一般发生在句中谓语动词所表示的动作之后。如：The girl writing a letter there can speak English very well./I have three letters to write.

7、-ing形式与动词不定式在句中作主语、表语、宾语时的区别。一般说来，表示一个比较抽象或泛指的动作时多用-ing形式。表示一个具体某一次的动作时，多用动词不定式，如：Our job is making steel. She likes playing the piano, but she doesn't want to play it today.
