间接引述的时态问题请帮看下下有无错误不合逻辑,拜托时态一直搞不清楚
以下自己写的文法但是时态一直是最大的致命伤
请汝等抬手帮看下有无任何不合逻辑或者错误请告知(顺便翻译下更好)

答案

这几句逻辑上和汉语类似,实际应用要看上下文,语法上大部分都对.
1.I know whom he gave it to.我知道他把它给谁了
2.I know whom he has given it to.我知道他把它给谁了
3.I knew whom he has given it to.语法不对,改为2或5
4.I know whom he had given it to.我知道他把它给谁了（实际很少用）
5.I knew whom he had given it to.我知道他把它给谁了
6.I know whom he will have given it to.我知道他要把它给谁
7.I knew whom he will have given it to.语法不对,改为6或9
8.I know whom he would have given it to.我知道他要把它给谁
9.I knew whom he would have given it to.我知道他要把它给谁
