助动词should,would的用法总结
以下是小编为大家整理的should,would的用法总结,希望能帮助大家更好地认识should,would的用法,提高英语水平。
should和would的用法:
should常译作“应该”,would常译作“愿意;会”.
1.should和would都可用于疑问句,表示征询意见或提建议.但它们比shall和will更委婉.如 Should we open the window?/ Would you mind asking you so many questions?
2.should和would都可用于肯定句或否定句.
(1)should译作“应该”,表示义务或推测.如 We should protect our environment.(义务) / You shouldn’t know him.(推测)
(2)would译作“愿意;会”,表示过去的意愿或意志.如 She said she would become a volunteer./ He promised that he wouldn’t fall behind others.
3.should和would都可作助动词,它们是shall和will的过去式,用于过去将来时,译作“将要”.should用于主语是第一人称,would用于主语是任意人称.如 He said we should / would move to the second floor.
1) would无词义,是will的过去形式,与动词原形构成过去将来时,用于第二、第三人称,例如:
He said he would come. 他说他要来。
比较:
"I will go," he said. 他说:"我要去那儿。"
变成间接引语,就成了:
He said he would come.
原来的will变成would,go变成了come.。
2)should也无词义,只是shall的过去形式,与动词原形构成过去将来时,只用于第一人称,例如:
I telephoned him yesterday to ask what I should do next week.
我昨天给他打电话,问他我下周干什么。
比较:
"What shall I do next week?" I asked.
"我下周干什么?"我问道。(可以说,shall变成间接引语时,变成了should。)
