根据规则,直接引语中用did一般过去时,变为间接引语,用过去完成时,had done,
所以有了had,see的过去分词就是seen.
请及时采纳,多谢!

英语的时态一致原则。请对比这两句：
he asked me ：“if you have seen him the night before？”（因为whether不能用在句首，所欲换成了if，但意思都一样。）
he asked me whether i had seen him the night before。
在第二句中，他问的话变成了宾语从句，这个时候就是英语的事态一致原则。
若主句式过去时，从句也必须用过去范围类的事态，即一般现在时要变为一般过去时，一般将来时要变为过去将来时，现在进行时要变为过去进行时等等。

他问我昨天晚上是否看到他了
whether时是否的意思
变为第三人称转述时多用whether
给分吧

what did he say? what did he tell you?为什么“say”和“tell”不用过去式,“said”、“told”? Do you still remember what he said 这句话后面能换成 what did he say 为什么? Did you hear what he said?=Did you hear ____ _____. Did you say what he said was true?该句属于什么从句?为什么Did you say that what he said was true?这个句子就是错的?请分析, what did he said改错 what did you say 和 what did you said 的区别不是过去是吗?为什么大家用what did you say而不用what did you said Do you still remember( ) A.that B what he said C did he say that D what did he say Do you still remember ( A that he said.B what he said.C did he say that.D what did he say I said he was wrong,did not 为什么did not I what he said what did he say放从句为什么选第一个 Did you say that what he said was true为什么要用that引导再加what,直接加what不行吗 Did you read the book last week?he said 改为间接引语 Did you see her last week ?he said改为间接引语 Did you write down what he said?哪个是谓语,哪个是宾语. 把直接引语变间接引语did you see her last week?'he said. Did you see her last week he said改为间接引语 Did you see her last week he said改为间接引语30词?急直接引语变间接引语Did you go to school He said to me
