关于从句 1、 拿到一个从句，首先要正确判断从句类型。 三大从句： （1）名词性从句：主语从句、宾语从句、表语从句、同位语从句 （2）形容词性从句：定语从句 （3）副词性从句：状语从句（时间、地点、条件、目的、结果、原因、让步、方式） 2、区别是什么从句应看主句。 主句不完整时，从句肯定是名词性从句。 主句完整时，从句可能是定语从句，状语从句， 或者是名词性从句里的一种——同位语从句。 名词性从句——主宾表同 主语从句What I say is true. 宾语从句He won’t believe what I say. 表语从句That is what I said. 同位语从句I told them the news that Rockets won the game today. · 怎样选择名词性从句里的引导词：名词性从句中缺什么意思就用什么意思的引导词。缺名词性成份时，指人用 who/whom，指物用 what；不缺意思和成份时用 that。That 只有在宾语从句中可以省略。例题如下： 1．___ the Olympic Games will be held in Beijing is known. A.不填 B. Whenever C. What D. When 2．There is a common belief among them ___ rubbish can and should be put to good use. A. which B. if C. whether D. that 3．He‟s bought a cottage for ___ he retires, with the money he saved. A. When B. where C. what D. which 4．It is known to all that Taiw an belongs to China. --Do you think it possible that w e take over Taiw an? --Of course. · It 经常在句中当形式主语、宾语，代替真正的主语、宾语，以避免头重脚轻。 例题如下： 1． It is pretty well understood ___ controls the flow of carbon dioxide in and out of the atmosphere today. A. That B. when C. w hat D. how 2．Why don‟t you bring ___ to his attention that you are too busy to do it? A. This B. what C. that D. it · 在名词性从句中，表“是否”时只用 whether 不用 if。例题如下： 1. Whether the president will come is not known yet. (主语从句) 2. The problem is whether we need it.（表语从句） 3. The problem whether we will build another school hasn‟t been settled.（...
