1.一般疑問句改成賓語從句時,先在從句前加上if/whether,然后把它變成陳述句序即可,當然也要注意時態(tài)的變化和some/any的變化.
如：Can you play football?
→ I don't know if/whether you can play football.
2.陳述句改成賓語從句時,先在從句前加上that（也可以不加）,照抄即可,當然也要注意時態(tài)的變化.
如：She is a student.
→ He said (that) she was a student.
3.特殊疑問句改成賓語從句時,疑問詞不變依然放在從句句首,其后變成陳述句序,當然也要注意時態(tài)等變化.
如：How old is he?
→ I wanted to know how old he was.
所以就多說了點可是，老師讓找的是 如何把一般疑問句改為陳述句
