托福语法介宾短语解析 2016年托福语法介宾短语解析 介词不能单独使用,而必须和其他词连用,这些词称作介词的宾语,它们共同构成的介宾短语常在句中作状语,作名词的后置定语,有时作某些动词的宾语补足语 考点一 名词作介词宾语 大部分介词的宾语都是由名词(包括代词)充当的,如:under the tree, during the day, 这一考点在题中多次出现 例题: (1) The development of mechanical timepieces spurred the search for ----with which to regulate them. (A) more accurate than sundials (B) more accurate sundials (C) sundials more accurately (D) more accurately than sundials 答案:B 解释:search for缺少宾语, 只有B是表达无误的名词词组, 可以作宾语;其他选项的比较形式都有错。 (2) Different species of octopuses may measure anywhere from two inches to over thirty feet in long. 应改为:in length. 解释:long 是形容词, 不能单独接在介词之后, 其名词形式length与in构成介宾短语, 表示长度 考点二 动名词作介词宾语 名词作宾语时,之后不能再接宾语,这一缺陷可由动名词弥补。 如:before doing the job , after getting back 改错题中常把应该用动名词作宾语的地方误用为名词或不定式,需留心陷阱 例题: (1) The Conestoga wagon, used for to carry heavy loads over long distances, originatedaround 1725 in a region of Pennsylvania occupied by the Conestoga Indians. 应改为:carrying. 解释:不定式不能作for的`宾语, 改为动名词即可 (2) Copper sulfate, spread in judicious amounts, kills algae ----harming fish or aquatic invert-ebrates. (A) does not (B) but does no (C) except (D) without 答案:D 解释:harming 是动名词形式, 因此要求前面的词是介词或可接动名词的动词. A B 可首先排除; C 虽是介词, 但与句意不符. (3) Mary Ann Hardy was known for her skill to paint miniature watercolor portraits on ivory. 应改为:in painting 解释:后置定语修饰名词,什么方面的技能,不能用不定式。 【2016年托福语法介宾短语解析】 本文来源:https://www.wddqw.com/doc/d82e3d38a11614791711cc7931b765ce05087a6b.html
