He said that if he had a million dollars ,he would give it to the zoo这句话有没有语法错误

Answer 1

He said that if he had a million dollars ,he would give it to the zoo这句话有没有语法错误？
答：这句话没有语法错误。
他的原话是：If i have a million dollars, I will give it to the zoo.
别想多了，这里没有虚拟语气，只是直接引语改为间接引语。
如果有上下文，可能没有表达出他想说的意思。比如他的原话是：
If I had a million dollars, I would give it to the zoo. 则为虚拟语气的句子，表示“如果我（将来）有10000美元的话，我就将它捐给动物园。
这说的是空话，气话，因为没有100000美元，所以才这么说，就象说：如果我中了100000元的彩票的话，我就分给你一半！
上面的这句话，再转述，就不一样了：
He said that if he had had a million dollars, he would have given it to the zoo.

Answer 2

没有语法错误！that引导宾语从句，宾语从句是一个以if引导的条件状语从句，主将从现

Answer 3

有，he would give it to the zoo改成he would have given it to the zoo

Answer 4

would give 改为would have given，虚拟语气，从句用一般过去式，主句用would have done

Answer 5
