賓語從句是作及物動詞或介詞賓語的句子。賓語從句中謂語動詞的時態(tài),要根據(jù)主句的時態(tài)和句義作相應的變化。賓語從句一定要用陳述句語序。賓語從句要用引導詞引導,引導詞有下面幾種。
1 用that 引導的賓語從句。
原句如果是陳述句,變?yōu)橘e語從句時,要用that引導。that引導賓語從句時,本身沒有詞義,只起引導作用,也??墒÷?。

2 用if或whether引導的賓語從句 。
原句如果是一般疑問句,變?yōu)橘e語從句時,要用if或whether引導,并把疑問句語序改為陳述句語序。

3 用who, whom, whose, which, what, how many, how much等關系代詞引導的賓語從句。
如果原句是由who等構成的特殊疑問句,變?yōu)橘e語從句時,仍然用who等引導,并將疑問句語序改為陳述句語序,但如果關系代詞本身作主語或修飾主語,則語序不變。
注意:①who等不可省略,②用了who等不可再用that。

提示
如果原句是祈使句肯定式,改為賓語時,要轉(zhuǎn)化為不定式肯定式,即to do sth.;如果原句是祈使句否定式,改為賓語時,要轉(zhuǎn)化為不定式否定式,即not to do sth.。
注意:①不定式前不可加that等引導詞,②原句中的please要去掉,③不定式不受句中謂語時態(tài)的影響,④如果原句中有稱呼語,要把這個稱呼語改為賓語,⑤原句中的said要改為asked, told等。
