助動(dòng)詞should,would的用法
1)should無詞義,衹是shall的過去形式,與動(dòng)詞原形搆成過去將來時(shí),衹用於第一人稱,例如: I telephoned him yesterday to ask what I should do next week. 我昨天給他打電話,問他我下周乾什麼。
比較: "What shall I do next week?" I asked. "我下周乾什麼?"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)詞原形搆成過去將來時(shí),用於第二、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.
