小學(xué)英語(yǔ)語(yǔ)法知識(shí)點(diǎn)：what至who+ever

　　1）what = the thing which；

　　whatever = anything

　　What you want has been sent here.

　　Whatever you want makes no difference to me.

　　2) who= the person that

　　whoever= anyone who

　�。ㄥe(cuò)）Who breaks the law will be punished.

　�。ㄥe(cuò)）Whoever robbed the bank is not clear.

　�。▽�(duì)）Whoever breaks the law will be punished.

　�。▽�(duì)）Who robbed the bank is not clear.

　　3) that 和 what

　　當(dāng)that引導(dǎo)定語(yǔ)從句時(shí) ，通常用作關(guān)系代詞，而引導(dǎo)名詞性從句時(shí)，是個(gè)不充當(dāng)任何成分的連接詞。賓語(yǔ)從句和表語(yǔ)從句中的that常可省略。What只能引導(dǎo)名詞性從句， 用作連接代詞，作從句的具體成分，且不能省略。

　　I think (that) you will like the stamps.

　　What we need is more practice.
