求高手指导几道英语选择题...关于定语从句的

1、to the degree （of）是一个固定的介词用法 因此从句中which代替
the degree 因而就是to which
2、因为that作为关系代词引导定语从句来修饰前一个that（先行词），而all
that 自然不是关系代词或关系副词，所以不能用来引导修饰前一个that的
定语从句
3、so可以和as也可以和that搭配 构成定语从句 区别如下：
so……as中as在从句中做成分，即从句成分残缺时用as充当从句的主语或
宾语
so……that中that在从句中不做成分，即此时从句的成分是完整的
4、这是虚拟语气中的固定用法 It is （high）time （that） sb did
or sb should do

5、这是非限定性定语从句which指代前面的several books
思路如下：We finally bought several books by Sharkespeare.This is
one of them.——>
We finally bought several books by Sharkespeare,of which
this is one.

1. Human facial expressions differ from those of animals in the degree to which they can be controlled on purpose.
人类的面部表情与动物面部表情的区别，在于他们能够被有意识地控制的程度。

2. Jim told us all that ____ he said so at the meeting was really true.
A that B all C what C all that
这句话分开看：
Jim told us all that
that he said

3. so +形容词＋名词＋that从句
(so ... that： 如此……以至于如此……以至于)
such ＋冠词＋+形容词＋名词＋that从句

4. 是省略了that

5. 这句话这样想：of which this is one= one of several books by Sarkespeare

Human facial expressions differ from those of animals in the degree ____ they can be controlled on purpose
这题先行词是the degree，应该是to the degree是在一定程度上

Jim told us all that ____ he said so at the meeting was really true.
A that B all C what C all that
all that是作主句的宾语，同时也是从句的先行词，因此用that作为从句的宾语

A computer is so useful a machine ____ we can use everywhere.
A that B which C as D what
这是so。。。that的用法，so。。。as 一般用于否定句中

It is high time ____ I went back home.
A on which B which C when D /
确实是that省略了

We finally bought several books by Sharkespeare,____ is one.
A which of them B which of whose C of which this D and of them
我最终买了几本莎士比亚的书，这是其中的一本，把关系词放到从句中应该是this is one of which，先行词是前面一整句话
