◆典型陷阱题分析◆
1. She was so angry and spoke so fast that none of us understood _______ he said meant.
A. that B. what
C. that that D. what what
【陷阱】可能误选B。许多同学一看选项首先就排除了C和D，认为这样两个“引导词”叠用的情况不太可能。在A和B两个选项中，选项A肯定不行，因为它引导宾语从句时不能充当句子成分，所以便选择了B。
【分析】正确答案选 D。第一个what 用作动词 meant 的宾语，第二个what 用作动词 said 的宾语，即在 none of us understood what what he said meant 中，none of us understood 为主句，what what he said meant 为宾语从句，而在此宾语从句中又包括有 what he said 这样一个主语从句。
2. After _______ had happened he could not continue to work there.
A. which B. how
C. what D. having
【陷阱】可能误选A。
【分析】最佳答案选 C。有的同学误选A，是因为认为介词后应接关系代词 which，但实际上，若填关系代词，其前没有先行词，这根据不是一个定语从句。另外，由于 had happened 缺主语，所以B和D也不能选。请再做下面一题(答案选B)：
He pointed to ______ looked like a tomb and said, “Ghost.”
A. that B. what
C. which D. as
3.“Is ______ you want to say?” asked the teacher.
A. this B. that
C. all that D. that all
【陷阱】根据中文字面意思误选A或B。
【分析】最佳答案选 D。假若选A或B，那么转换成陈述句即为：This is you want to say. / That is you want to say. 显然句中的两个谓语动词 is与want相冲突。选D组成的句子是 Is that all you want to say? 其中的that 为句子主语，all 为表语，you want to say 为定语从句，用以修饰all。
4. “When ______ leave for Japan?” “When ______ leave for Japan is kept secret.”
A. they will, will they B. will they, they will
C. they will, they will D. will they, will they
【陷阱】可能误选D，认为 when 后应用疑问句词序。
【分析】最佳答案选 B。第一个when引出的是一个特殊疑问句，故用疑问词序;第二个 when 引出的是主语从句，故其后用陈述句词序。请做以下试题(答案选C)：
(1) None knows if _______ that boy, but if _______ him, her parents will be disappointed.
A. she will marry, she will marry B. she marries, she marries
C. she will marry, she marries D. she marries, she will marry
(2) “Where _______ go to work?” “Where _______ go to work is not known.”
A. we shall, we shall B. shall we, shall we
C. shall we, we shall D. we shall, shall we
5. Someone is ringing the doorbell. Go and see ______.
A. who is he B. who he is
C. who is it D. who it is
【陷阱】几个干扰项均有可能误选。
【分析】此题最佳答案为D。首先可以排除A和C，因为空格处实为一个宾语从句，所以不能用疑问句词序。另一方面，但按英语习惯，当用于指代身份不明的人时，要用代词it，而不用 he 或she等。比较以下两句：
Mr Smith is at the door. He wants to see you. 史密斯先生在门口，他想见你。
Someone is at the door. It may be the postman. 有个人在门口，可能是邮递员。
第一句因前面指明了是 Mr Smith，所以后面用代词 he;而第二句因前面用的是不定代词 someone，说明此人身份尚不明确，故其后用了代词 it 来指代。
6. Don’t you know, my dear friend, ______ it is your money not you that she loves?
A. who B. which
C. that D. what
【陷阱】此题容易误选 A或B：选 A 的同学认为这是指人的，故用who;选B的同学认为这是非限制性定语从句，两者都是误认为这是定语从句(注意没有先行词)。
【分析】其实答案应选C。that引导的是一个宾语从句，用作动词 know 的宾语，它只是被句中的插入语 my dear friend 隔开罢了。请做以下试题(答案均为C)：
(1) Everyone knows, perhaps except you, _______ your girl-friend is a cheat.
A. who B. which
C. that D. what
(2) I think, though I could be mistaken, ______ she liked me.
A. who B. which
C. that D. what
(3) He told me the news, believe it or not, ______ he had earned $1 000 in a single day.
A. that B. which
C. as D. because
前面两题 that 引导宾语从句，后面一题 that同位语从句(修饰the news)。
英语语法大全：特殊同位语归纳
英语语法让很多学生都头疼，因为复杂难懂的句式和词组有时难以记忆。为大家整理了英语语法大全，本章主要介绍英语语法中的句子成分，希望对同学们的英语语法学习有所帮助。更多内容尽在。
特殊同位语归纳
当两个词或词组在一个句子中具有相同的语法地位而且描述相同的人或事物时，我们称它们为同位语。基本形式的同位语大家一般不会出错，但有几种同位语，或由于本身结构特殊，或由于它修饰的成分结构比较特殊，往往会引起误解。现小结并举例说明如下，希望引起同学们的注意。
1. 代词we, us, you等后接同位语
Are you two reading? 你们二人在看书吗?
They three joined the school team. 他们3人参加了校队。
She has great concern for us students. 她对我们学生很关心。
He asked you boys to be quiet. 他要你们男孩子安静些。
We girls often go to the movies together. 我们女孩子经常一起去看电影。
2. 不定式用作同位语
Soon came the order to start the general attack. 很快下达了发起总攻的命令。(to start the general attack与the order同位)
He followed the instruction to walk along a certain street where I picked him up. 他照吩咐沿某一条街走，我在那里接他上了车。(to walk along…与the instruction同位)
3. -ing分词用作同位语
He's getting a job tonight driving a truck. 他今晚得到一个开卡车的差事。(driving a track与a job同位)
She got a place in a laundry ironing shirts. 她在一家洗衣店得到一个熨衣服的职位。(ironing shirts与a place同位)
The first plan, attacking at night, was turned down. 第一个计划是夜袭，被拒绝了。(attacking at night与the first plan同位)
4. 形容词用作同位语
The current affair, the biggest in its history, is being held in Guangzhou. 目前的交易会，是有史以来规模最大的，正在广州举行。
He read all kinds of books, ancient and modern, Chinese and foreign. 他读了很多书，古今中外都有。
People, old and young, took to the streets to watch the parade. 老老少少的人都来到街头观看游行。
【注】这类同位语与定语比较接近，可转换成定语从句。如：
The current affair, the biggest in its history, is being held in Guangzhou.
=The current affair, which is the biggest in its history, is being held in Guangzhou.
5. none of us之类的结构用作同位语
We none of us said anything. 我们谁也没说话。
We have none of us large appetites. 我们谁饭量都不大。
They neither of them wanted to go. 他们两人都不想去。
They've neither of them succeeded in winning her confidence. 他们两人谁也没能赢得她的信任。
【注】同位语并不影响其后句子谓语的“数”，如：
学生每人都有一本词典。
正：The students each have a dictionary.
误：The students each has a dictionary.
请比较下面一句(谓语用了单数，因为each为句子主语)：
正：Each of the students has a dictionary.
6. 从句用作同位语(即同位语从句)
They were worried over the fact that you were sick. 他们为你生病发愁。
I received a message that she would be late. 我得到的信息说她可能晚到。
The news that we are having a holiday tomorrow is not true. 明天放假的消息不实。
The idea that you can do this work without thinking is wrong. 你可以不动脑筋做此工作的想法是错误的。
