Question

what 的用法

Life is 10% what happens to me and 90% of how I react to it.
请问上句中 what在句中起什么作用？

Answer 1

what一般是疑问词出现，比如what‘s
your
name
？
你叫什么名字，在这句疑问句中，what
是疑问词，成分是表语

what也可以和so连用，形成一个语气词，反问句。
so
what？
那又怎样？

what+if
what
if
：如果。。。。那该怎么办？

what
还是在名词性从句中的重要连接词，当名词性从句中的从句缺少主语或宾语，表语时，就用what引导或代替。

what还可以用在感叹句中，比如
what
a
beautiful
girl
she
is
=
how
beautiful
the
girl
is！

Answer 2

what
i
need应该是
is
的表语，并且what作
i
need的宾语，一般情况是IS后面的是它的表语，need在这是作动词。动词后面一般是宾语，这是固定用法，这句话是表语从句，第2句同上

Answer 3

此句中的 what 引导表语从句 what happens to me，且在该从句...happens to me 中充当主语。

Answer 4

1.

news
they

talking !
2.
what
wonderful
music
it
is
3.
what
great
fun
they
had
last
night
4.
what
a
good
time
i
had
in
beijing
last
year
!
5.

!
6.
what

sleep
it
is
!
这几道题的形容词之后，都有被修饰的名词，因此都用what来构成感叹句。
如果形容词后的名词在句中作主语，当然就用how。上面各句中黑体的人称代词都在句中作主语。

Answer 5

1.What+主语+及物动词

例句1：What he says is reasonable.

解析：What he says是主语从句，what在主语从句中作宾语。

2.what+主语+不及物动词/系动词+介词例句：The judge does not consider what each eyewitness looks like.

解析：what each eyewitness looks like是宾语从句，what在从句中作介词like的宾语。

3.What+主语+系动词

例句：He is not what he was ten years ago.

解析：本句意为“他不再是十年前的他了。”其中what he was是表语从句，what在从句中作表语。

4.What后接名词，作定语

例句1：I gave him what books I had.

解析：what books I had是宾语从句，what在从句中作books的定语。

5.What+及物动词+宾语或What+be done

例句1：What makes the matter worse has been puzzling me.

解析：其中What makes the matter worse是主语从句，what在从句中作主语。
