2012年托福考试语法辅导:常用介词
常用介词常用介词的用法
常用介词包括简单的,
如:in, on, at, from, to, like, of, for, after, before, by, with, to, since, between, etc.;
还有一些组合的,如:into, onto, out of, throughout, within, upon, etc.
这些词的具体用法需要下功夫搞清,在TOEFL题中都有所体现。
例题:
(1)
----one time, Manchester, New Hampshire, was the home of the most productive cotton mills in the world.
(A) On
(B) At
(C) By
(D) To
答案:B
解释:据选项可知需填介词,词组at one time意为“曾经、一度”,符合句意。
(2)
Saint Elmo’s fire is a luminous blue discharge of electricity sometimes seen when a thunderstorm.
应改为:in.
解释:when是连词,一般只引导从句,应该用介词引导宾语
