打的好辛苦啊.帮我解释下上面那几题为什么选那个答案.其他易错的答案为什么不可以选.我定于从句学的很烂,老是分不清什么时候用that 什么时候用what、when、where、which.有没什么诀窍啊.3Q.

1.I was surprised by her words,which made me reconize( A )silly mistakes i had made.
A.what B.that C.how D.which
what + 形容词+名词=how +形容词+the +名词,意思为：多么……
what silly mistakes:多么愚蠢的错误啊
2.Do you have any idea( B ) is actually going on in the classroom?
A.that B.what C.as D.which
Do you have any idea=do you know.后面直接加句子.你知道……吗?
What is actually going on in the classroom?教室里到底发生了什么?
3.My most famous relative of all,( A )who really left his mark on America,was Rob Sussel,my great-grandfather.
A.one B.the one C.he D.someone
one表示“一个人”,后面的定语从句修饰这个人,说明这是一个怎样的人,所以就不需要the
4.There is much chance (A) Bill will recover from his injury in time for the race.
A.that B,which C.until D.if
这是同位语从句,that 从句解释说明这个机会.同位语从句中只能用that.
同位语从句一般跟在某些名词后面,用以说明该名词表示的具体内容,比如I heard the news （that our team had won）.括号里的就是news 的内容.
5.--It's thirty years since we last met.
--But I still remember the story,believe it or not,( B )we got lost on a rainy night.
A.which B.that C.what D.when
这也是一个同位语从句,所以用that.believe it or not（信不信由你）是一个插入语.we got lost on a rainy night是the story 的内容.
6.She was so angry and spoke so fast that none of us understood (D)she said meant.
A.that B.what C.that that D.what what
首先,what she said是一个名词性短语,“她所讲的内容”,为方便解释,这里用it 代替.原句替换为none of us understood (D) it meant.
然后,因为understand 后面缺少一个名词.what it meant就构成了一个名词性短语.“它的意思”.
再把it 还原为what she said.
none of us understood (what what)she said meant.意思为：我们没有人理解她所说的话的意思.
7.Many young people in the West are expected to leave (D)could be life's most important decision---marraige---all most entire up to luck.
A.as B.that C.which D.what
leave 后缺少句子成分,所以用what.
8.---Is there any possibility (B)you could pick me up at the airport?
A.when B.that C.whether D.what
同位语从句用that
