今天你注意到雅思阅读填空题中的介词了吗？没有的话，我明天再来问一遍。

　　太多“烤鸭”宝宝都知道雅思阅读有很多套路，但往往都是学了芝麻忘了西瓜，前说后忘，或者老师带着做题就记得，自己单独做又开始晕乎乎。所以苏州环球教育张雯怡老师现在统一讲讲很有用但是很容易被大家忽略的介词。

　　首先介词有哪些？

　　按构词分类的话，有简单介词in, on, with, by, for, at, about, under, of等，合成介词into, onto, without, within, throughout等，重叠介词from among, until after, at about等，介词短语和分词介词ing。

　　按用途分类的话，表示时间、方位、进行、原因、方法、数量、与不及物动词搭配加宾语或者变被动。

　　其次，具体在填空题中怎么发挥作用？

　　这个方法特别针对阅读水平在6分左右的学生，因为该分数段的学生有一定词汇量，但是不太能看出同义词替换或者长难句的理解，所以需要依靠一些空格前后的解题点来帮助"锁定"正确答案。

　　介词的一大作用在于定位，举例C8T1P3 Question 39

　　The 39 _______________ between different test results was put down to the fact that sample groups were not big enough. 发现空格后有介词between，可以定位至原文" Yet some parapsychologists remain disturbed by the lack of consistency between individual ganzfeld studies. 很明显需要填空的内容是the与between中间的"lack of consistency"，单词不认识也能填，so easy.

　　同样道理，C6T4P3 Question 37

　　In addition, action can be taken through the _____________. 发现空格前有介词through，可以定位至原文"There are ways of dealing with the topic through the curriculum, using video, drama and literature." 也挺明显空格前的冠词和介词都对应，所以填空答案是"curriculum"，介词快速定位解题get了吗？

　　介词的另一大作用在于解题，区分干扰项

　　再举个例子：C11T1P1, Question 2, Question 7

　　Vertical farms would be located in 2_________________, meaning that there would be less need to take them long distances to customers.

　　be located in 词组表明空格处需要填坐落的位置，可定位到原文"multi-storey buildings in which food crops are grown in environmentally controlled conditions. Situated in the heart of urban centers." 这两句话中有三个in，不难发现in which 是定语从句的结构，不涉及解题，多半同学会被environmentally controlled conditions骗到，那么此时注意be located in 同义替换应为situated in，所以正确答案是urban centers。

　　来再一个例子，加深理解：The most probable development is that food will be grown on 7 __________ in towns and cities. 不难定位到原文"While it is possible that much of our food will be grown in skyscrapers in future, most experts currently believe it is far more likely that we will simply use the space available on urban rooftops."  

　　该句有2个介词，"on, in"都加粗了，粗心的烤鸭看到"摩天大楼skyscrapers"就激动得不行马上写答案了，但实际空格前的介词是on,所以正解应该是urban rooftops哟。

　　通过上面的分析，本文旨在引起大家对雅思阅读填空题特殊小词的重视，并给出一些学习意见。技巧虽好，但不要贪杯哦，备考周期比较长的同学，还是建议大家扎扎实实提高英语的阅读能力。
