1)should無詞義,只是shall的過去形式,與動(dòng)詞原形構(gòu)成過去將來時(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(shí),變成了should。)
2) would也無詞義,是will的過去形式,與動(dòng)詞原形構(gòu)成過去將來時(shí),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.。
