陈述句如何变宾语从句加that. We know (that )your are clever
一般疑问句如何变宾语从句 用whether 或 if。 We wonder if/whether you know about English
这里whether 与 if区别是:如果有or not ,用 whether。介词后用 whether。 whether+不定式。例如
1)We wonder whether go there or not .
2)We wonder whether to go there .
3)It depends on whether you like English
特殊疑问句如何变宾语从句仍然用原来的疑问词。例如:Do you know how long he will stay here?
1. 一般疑问句改成宾语从句时,先在从句前加上if/whether,然后把它变成陈述句序即可,当然也要注意时态的变化和some/any的变化。
如:Can you play football?
→ I don't know if/whether you can play football.
2. 陈述句改成宾语从句时,先在从句前加上that(也可以不加),照抄即可,当然也要注意时态的变化。
如:She is a student.
→ He said (that) she was a student.
3. 特殊疑问句改成宾语从句时,疑问词不变依然放在从句句首,其后变成陈述句序,当然也要注意时态等变化。
如:How old is he?
→ I wanted to know how old he was.
陈述句变宾语从句用that连接,一般疑问句用if或whether连接,特殊疑问句用原句中的就行,主谓不倒装。
