1)should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.
2) would也无词义,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.
