基础考法

考法1　考查介词的基本用法 高考对于介词基本用法的考查主要出现在语篇填空和短文改错中,常以在具体语境中考查高频介词的形式出现。 【典型例题1】(2017·全国Ⅰ卷)This trend,which was started by the medical community(医学界) 　　　　　a method of fighting heart disease,has had some unintended side effects such as overweight and heart disease—the very thing the medical community was trying to fight.  解析:as　此处表示这一趋势最开始被医学界作为与心脏病做斗争的一种方法。as“作为”。 考法总结as作为介词,除了用在固定搭配中,也需注意对其单独考查的情况。
