◆注意1:
1.that引导宾语从句，在从句中不充当任何成分,一般可省. 但在两个及以上宾语从句中，第一个宾语从句的that可以省，后面的宾从that不省。
在动词+形式宾语it+宾补+that宾从结构中，that一般不省。
The teacher told us (that) we should get to the classroom before 5:50 and that we should keep quiet.

I don’t know whether/if he will arrive on time.
I want to know whether he will come or not.

He didn’t know whether to tell him the news.
◆注意2：在宾语从句中,表示“是否”whether和if均可用, 但 ①介词后的宾从只用whether引导表“是否”; ② whether常与or not连用；③后面跟不定式时构成whether to do
sb. feel/ find/ think/ consider/ regard/ take/ make it + adj. / n. + that/to do…

I consider it impossible that he can complete the paper in three days.

◆注意3：如果主句中有形容词或名词作宾补时，一般用it来作形式宾语，把真正的宾语从句(或to do 结构)放在宾补后。
◆注意4：宾语从句中的否定转移—宾语从句前的主句动词是think, believe, imagine, suppose等词时，要将从句中的否定形式转移到主句中去。
我认为明天不会下雨。
I think it won’t rain tomorrow.
I don’t think it will rain tomorrow.

will it
is he
did she

◆注意5：带虚拟语气的宾语从句—主句动词是“insist, demand, order, suggest, propose, advise, desire, require, request”等时，宾语从句需用虚拟语气，即(should) do。

(should) be set free
◆注意6：whatever, whoever, whichever, however, whenever, wherever等词，既可以引导名词性从句，也可以引导让步状语从句。但是no matter + w-疑问词只能引导让步状语从句。

= No matter where you go, I’ll follow you faithfully.
