语法归纳：
Semi-auxiliaries can be divided into two classes those that cannot
be transformed into an “it …that + clause” construction
grammatically labened as Subclass I. The non-fiction verbs are so
called because they are not marked for tense or far subject-verb
concord. The negative non-fiction is formed by adding not or never
immediately before the non-finites.
课后练习精选：
Rephrase the following: using proper semi-auxiliaries
1.Tim hasn’t arrived yet. What’s wrong? He should have arrived at
five.

at five. 评述：is supposed to与should表示一样的意思。
2.He can be stupid at times.
答案：He tends to be stupid.
评述：这里的转换比较难以想到。要用到助动词tends to
Make a list of all the contracted forms and write the full forms
beside them
3.Nobody’s ever offered me a job abroad.
答案：Nobody has ever offered me a job abroad.
评述：要注意Nobody作为单数。
Add to where necessary

risk of losing everything they accepted his term.

it.

专四语法题：
1.The physicist has made a discovery, _____of great importance to
the progress of science and technology.
A. I think which is B. that
I think is C. which I think is
D. which I think it is
答案：选C 评述：该从句中有插入语I think,
插入语去掉后不影响句子的句意和结构，而D去掉后句子中主语重复，所以选C
2.Only take such clothes _____really necessary.
A. as were B. as they are
C. as they were D.
as are
答案：选D 评述：as引导定语从句修饰clothes，同时在从句中作主语，所以排除C和
D，而且该句中没有任何表示过去的时间状语，所以用一般现在时即可
3.You won’t get a loan _____you can offer some secutity.
A .lest B. in case
C. unless D, other than
答案：选C
评述：根据句意判断，前后两分句之间是条件关系，只有unless能符合句意。
4.This is an illness that can result in total blindness _____left
untreated.
A. after B. if
C. since D.
unless
答案：选B
评述：根据句意判断，前后两分句之间是条件关系，根据常识，应该是选肯定的引导词if，而不是否定的unless
5.He must give us more time, _____we shall not be able to make a
good job of it.
A. consequently B. otherwise
C. therefore D.
doubtlessly
答案：选B
评述：根据句意判断，前后两句分句之间是条件关系，只有otherwise能表达此意，consequently表结果，而且不能用来引导句子，而therefore表结果，doubtlessly也不能引导句子
6._____I sympathize, I can’t really do very much to help them out
of the difficulties.
A. As long as B. As
C. While
D. Even
答案：选C
评述：本题考查While的用法，可以用来引导让步状语从句。As虽然也可以引导让步状语从句，但不能用于此结构，而其他两词不可以引导让步状语从句。
7._____，I’ll marry him all the same.
A. Was he rich or poor B. Whether rich or poor
C. Were he rich or poor D. Be he
rich or poor
答案：选D 评述：本题考查让步状语从句的用法，Be he rich or
poor表达的意思是no matter he is rich or poor
8.David Singer, my friend’s father, _____ raised and educated in
New York, lived and lectured in Africa most of his life.
A. Who B. if
C. while D. though
答案：选D
评述：分析题意，这两个分句之间的关系为让步关系，四个选项中能表示让步关系的有while和though，但while后要接句子而不接短语，所以正确答案是though
9.Fool _____ Jane is, she could not have done such a thing.
A. Who B. as
C. that D. like
答案：选B 评述：本题考查as引导让步状语从句时倒装的用法。
10._____I like economics, I like sociology much better.
A. As much as B. So much
C. How much D. Much
as
答案：选D 评述： 考查Much as的用法，以为“虽然，尽管”，引导让步状语从句。
学习体会：
在学习完完整的助动词后发现做题时还是很有规律可循的，课上的例子很好的诠释了助动词的规则。虽然不定式只是开了一个头，发现非谓语覆盖面是非常广的，可以作大部分句子里的成分，除了谓语这个位置不可以，因此在下面非谓语的学习中，要更细致的去了解各个成分中的非谓语用法。
