托福考试改错题常考要点及例题分析（上）Ⅱ
|
二、介词 介词是考试中出现的比较多的一个部分，而其中考的最多的就是介词的固定搭配问题。由于篇幅问题，我们在这里仅仅举出几个例题，在说明书手册中我们完整的列出了所有的介词搭配，这些列出的搭配在以前的语法题中出现过，只不过有的时候是正确的选项，有的时候重复考。 (一) 介词搭配例：The teeth in the upper jaw function together those A B C in the lower jaw to cut, tear, and grind food.D 分析：和…一起，应该为together with，C错 例：The Allegheny Mountain range is rich of coal. A B CD 分析：B错改为be rich in 例：The rotation of the Earth on its axis is responsible to the A BC alternation of periods of light and darkness. D 分析：C错，应改为responsible for。形容词responsible后接名词作宾语时要加介词for。 (二) 最重要的两个介词1、介词of 多余或者遗漏例：Mosquitoes usually lay eggs, singly or in batches, on top stagnant water. ABC D 分析：D错，应改为top of stagnant。on top of …是因定表达法，意为“在…上面”。 例：Christopher Plummer is a Canadian actor who has AB starred in stage, television, and film productions on C both sides the Atlantic Ocean. D 分析：D错，应改为sides of the。 sides为名词，the Atlantic Ocean也是名词，中间明显少了一个介词。 2、介词by 一种情况表示被动，be+过去分词+by，另一种表示通过……的方式， by doing 例：The ceremony of marriage in the United States A B can be performed from a justice of the peace. C D 分析：D错，应改为performed by。谓语动词是被动式，performed的动作执行者应该由介词by来引导。 例：Along the east coast ,American Indian women's councils A could veto a declaration of war at refusing to B C D supply moccasins and field rations. 分析：D错，应改为by refusing。通过拒绝提供鞋子和粮食，表示通过某种方式做某事要用介词by,故将at refusing 改为by refusing。 例：Algebra is the branch of mathematics concerned with A operations on sets of numbers or other elements BC that are often represented at symbols. D 分析：D错，应改为by。动作的发出者应该用介词by来引导 |
