一道关于定语从句的英语题

It can help us learn about the real world more quickly,to learn ＿we want to learn and to think for ourselves.
Athat B what C which D something
正确答案是B,但为什么D不行,因为我认为we want to learn是一个定语从句,修饰something,又因为that在定语从句中做宾语,因此可省略,但为什么不行呢?请大家帮帮我,这是一道十分重要的题
定语从句中,在先行词是someting这样的不定代词时，一定要用that引导这对吗?为什么

Answer 1

Y_小卷_Y - 试用期 一级 的解释something做先行词时定语从句的that不能省略不错

但这道题更合理的解释是

to learn ＿we want to learn and to think for ourselves.
~~~~~~~~~~~~~~~~~~~~~~~~
注意后半句to think for ourselves，think是及物动词，需要宾语，这里应选 what， 既是we want to learn 的宾语，又是think的宾语。

如果要该成定语从句应该是
something that we want to learn and something that we think for ourselves.

如果理解为 and 连接两个不定式 to learn and to think 一起做want的宾语，语法没错，意义是不对的。因为不可能是 want to think
something that we want to learn and to think for ourselves.

所以 to think 不是want的宾语，而是前面learn的宾语从句，作为一个句子，它需要自己宾语what。

至于您的第二个问题先行词
我给你列出必需要要that的场合

1先行词是不定代词

I\'ll read you someting that is worth listening to.

2先行词是形容词的最高级或序数词

What is the first English novel that you need.

3先行词带有no only very

He give me the very book that i want.

4先行词有last next

Let\'s take the next train that is espress train.

5先行词有same

Don\'t make the same mistake that I made before.

6先行词有who

Who that has sympathy( 同情心)can\'t laugh on the occasion.

7先行词既有人又有物

He talk of the men and book that had interested him.

8先行词有which为避免重复也用that

9先行词做表语

China is not the country that it was.

Answer 2

你好。答案是C.
我告诉你一个简单的办法。
因为在许多场合，in
case==
if,所以，你就把句子写成两句，这样就容易理解了:1
She
may
have
missed
her
train.
2
IF
THAT
HAS
HAPPENED,she
won't
arrive
for
another
hour.
(THAT==She
may
have
missed
her
train)
现在，你看容易吗?

Answer 3

这道题考察的其实是宾语从句
what在这里做learn的宾语，someting不能引导宾语从句
如果非要看作定语从句的话，that应该是不能省的，因为在先行词是someting这样的不定代词时，一定要用that引导

像all只能用that引导，one只能用which引导一样，有的先行词必须由特定的次引导，这应该是一种语法习惯吧

Answer 4

what=all that不等于something that。
就是说what包括所有的thing，不只是something。

Answer 5

C
