1、第三讲 名词性从句 第一课时 知识过关课,李仕才,1主语从句作主语，主句谓语动词通常用单数；为使句子平衡，常用it作形式主语。 2表语从句还可以用as if，as though引导。 3表示“是否”，引导宾语从句时可用if或whether，但在介词后或直接与or not连用时，只能用whether引导；引导表语从句、同位语从句或位于句首的主语从句时，只能用whether，不用if。 4同位语从句一般放在fact，news，idea，promise，suggestion，advice等抽象名词之后，说明或解释这些抽象名词的具体内容。多用that引导，不能由which引导。 5当宾语从句又带有补语

2、时，要用it作形式宾语。,6在表示“建议”“命令”“要求”，如advice，suggestion，proposal，order，demand，request等词后的名词性从句，其谓语通常用“(should)动词原形”。 7that引导名词性从句时，不作任何句子成分；但that引导定语从句时，它代表先行词，而且在从句中作主语、宾语或表语。 I still remember the promise that he made 我依然记得他许下的诺言。(定语从句) The naughty boy made a promise that he would never make a noise 那个淘气的

3、男孩保证说他以后再也不吵闹了。(同位语从句),8what可引导名词性从句但不能引导定语从句。what引导名词性从句，有时相当于“the名词that”，表示“(所)的”。 What(The thing that) you said was right. 你所说的是正确的。,读语篇，悟语法。反复朗读下列短文，领悟画线和黑体部分，思考：画线部分在全句中作何种成分，即是什么从句，该从句为什么要由这个黑体词来引导。 What worries my classmate Maryk a lot these days1 is that she puts on too much weight and she i
