助動(dòng)詞should,would的用法總結(jié)
以下是小編為大家整理的should,would的用法總結(jié),希望能幫助大家更好地認(rèn)識(shí)should,would的用法,提高英語(yǔ)水平。
should和would的用法:
should常譯作“應(yīng)該”,would常譯作“愿意;會(huì)”.
1.should和would都可用于疑問(wèn)句,表示征詢意見(jiàn)或提建議.但它們比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譯作“應(yīng)該”,表示義務(wù)或推測(cè).如 We should protect our environment.(義務(wù)) / You shouldn’t know him.(推測(cè))
(2)would譯作“愿意;會(huì)”,表示過(guò)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都可作助動(dòng)詞,它們是shall和will的過(guò)去式,用于過(guò)去將來(lái)時(shí),譯作“將要”.should用于主語(yǔ)是第一人稱,would用于主語(yǔ)是任意人稱.如 He said we should / would move to the second floor.
1) would無(wú)詞義,是will的過(guò)去形式,與動(dòng)詞原形構(gòu)成過(guò)去將來(lái)時(shí),用于第二、第三人稱,例如:
He said he would come. 他說(shuō)他要來(lái)。
比較:
"I will go," he said. 他說(shuō):"我要去那兒。"
變成間接引語(yǔ),就成了:
He said he would come.
原來(lái)的will變成would,go變成了come.。
2)should也無(wú)詞義,只是shall的過(guò)去形式,與動(dòng)詞原形構(gòu)成過(guò)去將來(lái)時(shí),只用于第一人稱,例如:
I telephoned him yesterday to ask what I should do next week.
我昨天給他打電話,問(wèn)他我下周干什么。
比較:
"What shall I do next week?" I asked.
"我下周干什么?"我問(wèn)道。(可以說(shuō),shall變成間接引語(yǔ)時(shí),變成了should。)
