动名词作主语动词为什么加ing

动名词作主语动词为什么加ing

to do 也行，因为做主语通常要名词或代词性质的词，所以用ing表动名词

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.
