ACT英语：介词考点分析

　　ACT英语中，介词也是ACT考察的一个重点。一般来说，ACT主要考察句中介词的准确性。下面课窝网通过几个例题分析介词的考点。

　　知识点概括

　　介词：介词是一种虚词，不能单独做句子成分，只能用在一个名词、代词或相当于名词的结构之前，可以与后面的词一起构成介词短语。介词可分成以下三类：

　　简单介词

　　包括in, at, on, with, by, for, before, along, across等。

　　I didn't like being alone at home.

　　Peter walked along the street alone.

　　分词介词

　　包括during, following, considering, concerning, regarding, touching, speaking, judging, including等。

　　There are 10 people including you.

　　Wages have fallen by more than twenty percent during the past two months.

　　介词短语

　　一个或两个简单介词和一个或几个其他词类构成一个短语，作用相当于一个介词，这就叫做介词短语。这类介词的末尾总是跟一个简单介词，如according to, because of, by means of, in addition to, in front of, in spite of, apart from等。

　　They both played the game according to the rules.

　　It is mainly because of my faults.

　　考题分析

　　通过几个考题，具体看一下介词的考法：

　　例题练习 1

　　In the dusk of a late summer evening, I walked quietly, with a small gathering of people toward a

　　shelter at the edge of a field in northern Indiana.

　　F.  NO CHANGE

　　G. On

　　H. With

　　J.  From

　　考点分析

　　考查简单介词在句中的准确使用。

　　此题的解题关键是掌握介词in的具体用法。

　　此题中the dusk of a late summer evening在一个晚夏夜晚的薄暮中，此处我们可以联想到最简单的介词常规用法，in the evening，故此处用in是最准确的。所以正确答案是F。

　　例题练习 2

　　Some parents have been moved by worries about the lyrics’ influence on their children to seek ways of restricting access of songs they deplore.

　　A. NO CHANGE

　　B. access by

　　C. access to

　　D. excess of

　　考点分析

　　考查动词和介词的固定搭配。

　　此题的解题关键是掌握动词access常用的介词搭配。

　　此题中的access，我们常用的搭配是access to接近；有权使用。所以正确答案是C。

　　例题练习 3

　　The court agreed with Kevin that a person's right for wearing clothing of his or her own choosing

　　is, in fact, protected by the Fourteenth Amendment.

　　A. NO CHANGE

　　B. of wearing

　　C. to wear

　　D. wearing

　　考点分析

　　考查名词和介词的固定搭配。

　　此题的解题关键是掌握名词right常用的介词搭配。

　　此题中的right的常用搭配为：have right to do sth.有权利做某事，故此处应修改介词，且将动名词wearing改成动词原形。所以正确答案是C。

　　例题练习 4

　　As partial evidence, Dr. Cheng cites the fact that Halobates spend their -lives walking on top of the water.

　　Which of the following alternatives to the underlined portion would NOT be acceptable?

　　F. upon

　　G. top of

　　H. atop

　　J. on

　　考点分析

　　考查不同介词的相同词义。

　　此题的解题关键是判断准确介词的词义。

　　此题中原句中使用了on top of，意思是在……之上，而选项中的upon/atop/on，都是此意，G选项中的top of并不是介词。所以正确答案是G。
