Dan:
1)He watched TV last night.的watched已經是一個過去式主動詞, 所以不須亦文法上不可以再加一個叫' 動詞是'-----如am, was, is, are, were, shall, will等
任何一個在它(主動詞)的後面。
2)Had是過去完成式動詞, 它多有特殊意思才用如:
Had you read that book before you started with this one?
在你開始(看)這本書之前已經看完過(had read)了那一本了嗎?
Did you read that book?文法上也沒錯, 但用法要看塲合(上文下理)如:
Did you read that book? If you did, I am going to ask you some questions
about it
你讀過了(Did you read)那書了嗎 ?如你有, 我現在就問你一些有關它的問題。
這樣用did就對了。
