except 后面接不定式与接动名词的区别

2个回答

  • Ⅰ.动名词和不定式做主语的相同点

    1.不定式短语和动名词做主语时,常常为了保持句子的平衡,用it来做形式主语,如:

    It is not easy to learn English well.

    It is no use asking him for help.

    2.如果主语用了不定式,表语和宾语也要用不定式;主语用了动名词,表语和宾语也要用动名词,这在英语中称为对称性,如:

    To see is to believe.= Seeing is believing.(眼见为实)

    (85)It is better to stay home than _A__ out.

    A.to go B.going C.go D.gone

    Ⅱ.动名词和不定式做主语的不同点

    1.不定式做主语常表示具体的某一动作;表示泛指或一般的抽象的概念时,多用动名词,如:

    (92)_B_ is a good form of exercise for both young and old.

    A.The walk B.Walking C.To walk D.Walk

    2.在”There/It +be+ no use(good/help/need)”之后常用动名词做主语,而少用不定式,如:

    It /There is no use crying over the split milk.

    It /There is no help taking this medicine.

    ★但是如果该句型中用了for引出不定式的逻辑主语,就只能用不定式,如:

    (93) There is no good for us to do that exercise.

    3.不定式可以和when,where,how,what,whether等连用,在句子中做主语,宾语和表语,而动名词则不能,如:

    How to solve the problem is a hot potato.

    Where to put the box seems hard to decide.

    Whether to do it hasn’t been decided.

    What to do next is up to you.
