Answer 1

你不会做这道题主要是对宾语从句不够熟悉，英语的各种从句都很重要，希望能帮到你，好好体会下：

宾语从句：

宾语从句是英语复合句中的其中非常重要的从句之一。它是用一个句子做另一个句子的宾语，将这个句子叫做宾语从句。宾语从句做介词或及物动词的宾语。

A,由that 引导的陈述句性的宾语从句，在很多动词如say, think, wish , hope, see, believe, agree, expect, hear , feel等动词后。连词that只起连接作用，在从句中不做句子的成分，也无词汇意义，在口语中常被省略，但在大多数情况下还是以不省为好，特别是在笔语中。

B,由连词if、 whether 引导的表示“是否…”的宾语从句。Whether,if 在从句中不做句子的成分，一般情况下，whether和if 可以替换。

C,由wh-引导的宾语从句。连接代词who,whom,whose, what, which,和连接副词when, where, why, how 等连接的宾语从句，它们在句中即有连接从句的作用，又在句中充当句子的成分。

关于宾语从句的一些练习：
1.Can you see________?
A. what he’s reading B. what is he reading
C. what does he read D. he reads what
2.Does Jack come from Japan? Do you know?(合并成一个句子)
Do you know_____Jack _____from Japan?
3._What did your son say in the letter?
_He told me that he___ the Disney would the next day
A.will visit B. has visited
C. is going to visit D. would visit
4.He didn’t know__________
A.what’s the matter B.what the matter is
C. what was the matter D. what the matter was
5.Somebody called you just now,but I didn’t know____
A.who were they B. who they were
C. who was it D. who it was
6.I want to know_____
A.what is his name B. what’s his name
C. that his name is D. what his name is
7.---Could you tell me ___she is looking for?
---Her cousin,susan.
A.that B.whose C .who D.which
8.---What are you searching the Internet for?
---I’m trying to find out____.
A.What is the difference between SARS and BIRDFLU
B.How many persons have died in Iraq
C.How to protect our environment
D.Why is our Chinese team be able to beat Korea

Answer 2

D.what为正确选项。what引导的宾语从句what she was five years ago做介词from的宾语。
考点是what引导的宾语从句与that引导的定语从句的区别。它们最大的区别是what引导的宾语从句没有先行词（即被修饰的名词或代词）。如有先行词，则要考虑是否是定语从句。
本题很容易出现选 B.that的错误。这里没有先行词，故不是定语从句，不能选that。

Answer 3

what 引导的的确是宾语从句，____ she was five years 在此宾语句中作宾语成分，但要注意，a lot 后面是一个定语从句，先行词是mother,只不过省略了who is ,完整的是 who is different from what~~~~

Answer 4

what在此处起引导宾语从句作用,同时它又在从句中充当表语成份.相当于the things that...虽说that也可引导宾语从句,但它只起引导作用,不作从句任何成分.如:I take back what I said.我收回我说的话.
