解析：倍数关系题
正确答案为B
错选为D没有正确掌握倍数的表示方法。
倍数一般有三种表示方法：
a 主语+谓语+倍数+as+adj.+as;
b. 主语+谓语+倍数+the size（amount,length...) of...;
c. 主语+谓语+倍数+adj./adv.比较级+than...
本题考查的是第二种表示方法。
2.Aren't you tired? I__ you had done enough for today.
A. should have thought B. must have thought
C. might have thought D. could have thought
解析：情态动词题

Should have done 表示本应该做某事 而实际没做，句意为：你不累吗？我本应该想到你今天干的够多的了。
3.It seems that she was there at the conference." The sentence means that___.
A. She seems to there at the conference.
B. She seemed to there at the conference.
C. She seems to have been there at the conference.
D. She seemed to being there at the conference.
解析：句式变换题
正确答案为c
而错选A 我从was判断时态为过去时 就排除a和c
而b句子错误 所以选d
正确解析为：seem 后接动词不定式，也常用 It seems that 结构。即将简单句变成复合句，它们之间具有同义可换性。本题的 It seems that she was there at the conference. 是一个主系表结构，谓语动词seems表明是现在看起来，而表语从句中的动词是was，说明这是现在对一个过去事情的判断。因此改写成简单句后，seems的时态不变，而to be应该用to have been，表示对过去事情的判断。
4.In“How much do you think he earns?" how much is__ of the sentence.

6.After__seemed an endless wait,it was his turn to enter the personnel manager's office.
A. that B. it C.what
D. there
解析：宾语从句题
正确答案为C. 做错的原因是句意不清楚，对句子结构的分析是个盲点。
错选为D
考查宾语从句。本句中after后需要一个宾语从句，该宾语从句缺主语，因此需要一个作主语的连接代词，四个选项中只要what可以在宾语从句中充当主语。
7. Dr. Johnson is head of the department,___ an expert in translation.
A.or B.either C.but D.and
解析：句意理解题
错选为 C
我的理解是 他既是系主任，也是翻译专家，either 肯定句中“也”的意思 。
正确的答案为 D 约翰逊博士是系主任，翻译专家。两者之间是并列关系，所以用并列连词and.
8.The police had difficulty in ____ the fans fi'om rushing on to the stage to take photos with the singer.
A. limiting B. restraining C. confining D. restricting
解析： B. 我错选为A
本题为动词辨析题。limit，restrict和confine为近义词。limit一般指事先确定空间、时间或数量的极限；restrict意为“限制”，指限制某物的大小、数量等。confine侧重施加不可逾越的限制，有时暗示束缚、囚禁。restrain意为“阻止，抑制”，通常与from搭配，表示“阻止某人做某事”，符合此处语义和语法关系，故选B。句意：警察经常很难阻止歌迷冲到舞台上和歌手照相。
9.Which of the following sentences has an object complement?
A. The directors appointed John manager.
B. I gave Mary a Christmas present.
C. You have done Peter a favour.
D. She is teaching children English.
解析：句子成分题
我错选为B
答案为A. 没有掌握句子成分。对于词组在句子中所做的成分这一知识点没有掌握。
宾语后面加上一个词或一个短语用来对宾语的特征、状态等情况进行补充说明，这个成分称为宾语补足语。它和前面的宾语一起形成“复合宾语”，宾语和宾语补足语之间存在一种逻辑上的主谓关系。选项A中的manager和宾语John之间存在逻辑上的主谓关系，故为宾语补足语。而双宾语是指句中包含两个宾语，一个是直接宾语，另一个是间接宾语。即“双宾语=直接宾语+间接宾语”，往往指人的为间接宾语，指物的为直接宾语，他们之间是非主谓关系。所以后三个选项中的动词后面都是双宾语。
10.____ should not become a serious disadvantage in life and work.
A.To be not tall B. Not being tall
C.Being not tall D.Not to be tall
解析：非谓语动词
错选为C，搞错了否定词的位置。
句意为长得不高不该成为生活和工作中的严重不足之处。
考查的非谓语动词，本句中缺失主语，动名词短语做主语时，通常用于表示一件已知的事或经验。不定式短语通常用来表示一件未完成的事或目的。本句中“长得不高”是一件已知的事情，
所以选择动名词短语作主语，表示否定意义，not要放在动名词前面，所以选择B.

解析：语法功能题
错选为D 理解为他动身去北京。表示目的。
正确答案为A. 意为她是为了好玩才说了，但是其他人当真了。For fun 表示目的。B项为尽管非常努力，但那个队伍还是没能赢得比赛。表示转折。C项意为琳达已经在那家公司工作了20年。表示时间。
12.Which of the following italicized phrases indicates a subject-predicate relation（主谓关系）？
