(2)whoever, whomever是强语势\无论谁\不含有疑问意味，在引导名词性从句时, 在从句中作主语时用whoever, 作宾语是用whomever/whoever. ①You can give it to whomever/whoever you like.
②Whoever wants to see this film can go with us tonight. 四. what/whatever与which/whichever的区别 见5+3P95 五. because, why引导表语从句 见5+3P95 添加：Things are not always as they seem to be.
（as: 像?一样；此句中的as不是“因为”的意思，当as意为“因为”时，不能引导表语从句） 添加：
六. think, believe, expect, imagine, suppose 宾语从句 ① I don’t think he is right. ② I don’t think he is right, is he? You don’t think he is right, do you? ③ What do you think he is doing? ④ Do think he is coming? Yes, I think so.
No, I don’t think so. / No I think not.
注意：I hope/am afraid/guess so. I hope/am afraid/guess not. 七. 比较不同句型
① Jerry told us what/all that/ / all /all what he had seen abroad. ② It is known to all that China has joined the WTO. ③ As is known to all, China has joined the WTO.
④ What is known to all is that China has joined the WTO. 八.. 疑问词-ever , 即 whatever, whichever, whomever, whenever?.
① 既可以引导名词性从句≠ no matter+连接词引导的从句
I believe whatever he says. (此句不能用no matter what替换)
② 也可以引导让步状语从句 = no matter+连接引导的从句
Whatever he says, I will never believe him.
= No matter what he says, I will never believe him. 九. whether 与 if 的区别总结
相同点:
①引导动词的宾语从句时，whether/if都可用
②引导动词的宾语从时，whether?or not = if ?. or not
③ 如用it作形式主语，那后置的真正的主语从句可用whether/if引导,但还是whether常见
不同点：
①在表语、同位语从句中只能用whether ②主语从句位于句首,只能用whether,
③如用it作形式主语，后置的真正的主语从句中含有表选择意义的or时，必须用whether ④直接跟动词不定式时,只用whether
⑤宾从中，后面紧跟or not 时,只用whether ⑥在介词后, 只用whether
⑦某些动词后（discuss/decide/depend）只用whether
⑧注意区别if引导的宾语从句和条件状语从句。用 if 会引起歧义时，往往用 whether 表“是否” ⑨宾语从句为否定句时用if
