几组不可不防的“ 陷阱题 ”英语中很多试题是有规律可循的，在平常的练习中应注意归纳总结、举一反三，以达到事半功倍的效果。一、分析句子结构，避免掉入陷阱1. ______ is reported in the newspaper, some artistic treasures will be on show at the exhibition on the weekend.A. It B. As C. That D. What2. ______ has been proved that a computer is an important aid in classroom teaching.A. It B. As C. That D. What3._______ is known to us all is that English is the most widely used language in the world.A. It B. What C. As D. That[解析]1. B。此题考查的是 as 引导的非限制性定语从句。as 在从句中作主语，其引导的句子可放句首，也可放句后。但 which 引导的非限制性定语从句只能放在句后。试比较：As is reported in the newspaper, some artistic treasures will be on show at the exhibition on the weekend.Some artistic treasures will be on show at the exhibition on the weekend ， which/as is reported in the newspaper.2. A。it 在句中作形式主语，真正的主语是 a computer is an important aid in classroom teaching。3. B。此题考查 what 引导主语从句的用法。二、理解句意，找准时间点1. It is a long time ______ I lived in that small mountain village with these farmers.A. when B. that C. before D. since2. How long do you think it will be ______ housing prices start going up again?A. when B. that C. before D. since3. — Did Jack come back early last night?— Yes. It was not yet eight o’clock ______ he arrived home.A. when B. that C. before D. until[解析]1. D。根据句意“我与这些农民住在那个小山村已经很久了”， 即动作从过去某个时间开始一直持续到现在，可知用 since。2. C。题干为疑问句，可将其还原为陈述句：It will be+时间段 ______ housing prices…, 这样很容易看出本题考查的句式是 It will be +时间段 +before…(要过多长时间才……)。再如：It will be years before we meet again. (很多年后我们才能见面。)...
