助動詞should,would的用法總結
以下是小編為大家整理的should,would的用法總結,希望能幫助大家更好地認識should,would的用法,提高英語水平。
should和would的用法:
should常譯作“應該”,would常譯作“愿意;會”.
1.should和would都可用于疑問句,表示征詢意見或提建議.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“應該”,表示義務或推測.如 We should protect our environment.(義務) / You shouldn’t know him.(推測)
(2)would譯作“愿意;會”,表示過去的意愿或意志.如 She said she would become a volunteer./ He promised that he wouldn’t fall behind others.
3.should和would都可作助動詞,它們是shall和will的過去式,用于過去將來時,譯作“將要”.should用于主語是第一人稱,would用于主語是任意人稱.如 He said we should / would move to the second floor.
1) would無詞義,是will的過去形式,與動詞原形構成過去將來時,用于第二、第三人稱,例如:
He said he would come. 他說他要來。
比較:
"I will go," he said. 他說:"我要去那兒。"
變成間接引語,就成了:
He said he would come.
原來的will變成would,go變成了come.。
2)should也無詞義,只是shall的過去形式,與動詞原形構成過去將來時,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?"我問道。(可以說,shall變成間接引語時,變成了should。)
