【AEAS考试网】英语陷阱题详解介词类（一）
为了提高参加AEAS考试的同学的英语水平，AEAS考试网特别为同学们带来一些考试技巧。这次介绍的是英语陷阱题详解介词类（一）。
1. "You went late _______ the stadium yesterday evening, didn't you?" "Yes, my wife was a little late _______ the supper."
A. to, with B. for, with
C. for, for D. at, for
【陷阱】容易误选 B 或D。
【分析】答案应选 A。第一空填to 比较好理解，因为此处的late为副词，用以修饰 go to the stadium 中的动词go；而第二句的 with 则是许多同学不容易想到的，相反，更多地可能是想到 for，现将两者区别如下：be late for表示做某事迟到，而be late with 表示做某事做晚了(=be late in doing sth)。比较：
We were late for dinner. 我们吃饭迟到了。
We were late with dinner [=in having dinner]. 我们吃饭吃得迟。
句中 my wife was a little late with the supper 的意思是"我妻子准备晚饭稍迟了一点"。
2. Sometimes our opinions differ _______ what we choose to observe and how we deal with what we've observed
A. which B. since
C. because D. because of
【陷阱】容易误选C。因为按英语语法习惯，because是连词，其后接句子；而because of是复合介词，其后接名词、代词或动名词等。
【分析】此题答案选D。because 作为从属连词，主要用于引导原因状语从句，既然是引导一个从句，也就是说它的后面不能再连用"引导词"。如：
He was angry because we were late. 他很生气因为我们迟到了。
They can't have gone out because the light is on. 他们不可能出去了，因为灯还亮着。
Bread is cheap in this supermarket because they bake it themselves.这家超市的面包是自制的，所以便宜。
假若，一个从句已经有了自己的"引导词"，那么它前面就不宜再用 because 这个连词了。如：
She got angry because of what you said. 她哭是因为你说的话。
句中的 what 相当于 the thing that，也就是说 what you said 相当于 the thing that you said。其中 the thing 用作 because of 的宾语，而that you said 为修饰 the thing 的定语从句。
He lost his job because of how he treated his boss. 他因为对老板的态度(不好)而丢了工作。
句中的 how 相当于 the way in which，也就是说 how he treated his boss相当于 the way in which he treated his boss。其中 the way 用作 because of 的宾语，而in which he treated his boss 为修饰 the way 的定语从句。
3. "How long have you been an actor?" "_______ 1995, when I graduated from college."
A. After B. In
C. From D. Since
【陷阱】几个干扰项均有可能误选。
【分析】最佳答案为D。若仅从答句来看，四个答案都说得过去。但若结合问句的语境以答案应选D，因为其余三选项填入空格均不能回答问句所提出的问题。比较：
"When did you became an actor?" "_______ 1995, when I graduated from college."
A. After B. In
C. From D. Since
此题选B，因为问句问的是when(何时)，所以用 in 1995 来回答便顺理成章。
请再看两题：
(1) "How long have you worked on the farm?" "____ the end of last year."
A. In B. By
C. At D. Since
答案选D，用 since the end of last year 回答 how long，即问句问"工作了多久"，答句说"自去年年底至今"。
(2) "How long will you work on the farm?" "____ the end of next year."
A. In B. By
C. At D. Since
答案选B，问句问"将工作多久"，答句说"工作明年明底"。
(3) "When did you leave the farm?" "____ the end of last year."
A. In B. By
C. At D. Since
答案选C，问句问"何时离开"，答句说"去年明底离开"。
