04重难点突破 名词性从句基本知识的综合运用
名词性从句考点的解题关键：
1．确定是名词性从句
空处无提示词，先确定主句的主谓结构，再确定空处和空后的内容在主句中充当主语、宾语、表语或同位语。
2．利用两个技巧搞定名词性从句
Tip1：分析句子成分
(1)从句中缺少主语、宾语、表语，用连接代词what、wh、whm、which、whatever等。
(2)从句中缺少状语(结合句意判断)，用连接副词where (表地点)、when (表时间)、hw (表方式)、why (表原因)等。
(3)从句中不缺成分，句意缺少“是否”，用if/whether。
(4)从句中不缺成分且句子意义完整，用that。
Tip2：结合句意和引导词的本义解题
有些引导词在句中有很鲜明的意义，如whether/if (是否)、whever (无论谁)、whatever (无论什么)、because (因为)、why (为什么)等。结合句意和语境，不难解决这类试题。
3．牢记what和that的区别
(1)that没有词义，且在从句中不作任何成分。
(2)what在从句中表示 “……的(东西)” (有时候可以不译)，在从句中充当主语、宾语、表语、定语等成分。
1．what与that
(1)that在名词性从句中具有“两无”“一不”特征——无意义、无成分，(除宾语从句外)不可省略。
that在名词性从句中没有意义，而且不充当句子成分。that引导宾语从句作及物动词的宾语时可省略；在引导主语从句、表语从句和同位语从句时，that不可省略。
I think (that) yu shuld turn t the teacher fr help.
我认为你应该向老师寻求帮助。
My decisin is that all f us are t start at 6 'clck tmrrw mrning.
我的决定是我们所有人明天早上6点出发。
(2)what在名词性从句中具有“两有”“一不”特征——有意义、有成分，不可省略。
what在引导名词性从句时，有一定的意义，一般可译为“……的东西/事情/话等”；what在从句中充当主语、宾语、表语和定语，不可省略。
What was mst imprtant t her, she tld me, was her family.
她告诉我，对她来说最重要的是她的家庭。
2．whether与if
在引导名词性从句时，这两个连词常常通用。但是在下面情况下，一般用whether。
(1)引导主语/表语/同位语从句时；
(2)引导的从句在介词后时；
(3)与r nt直接连用时；
(4)与动词不定式连用时。
3．what与which
what与which在引导名词性从句时，既可以作主语、宾语，又可以作定语。但如果有明确的“范围”时，应用which，而不用what。
语法填空
