宾语从句
1.宾语从句的引导词
引导词 作用

连接代词 whichever，whatever, 在从句中作主语、宾语、表语或定语

不定式/从句)后置。
(1)动词find/feel/think/consider/make＋it＋宾补(形容词或名词)＋不定式/从句

适的时态；主句为过去的某种时态，从句须用相应的过去的某种时态。当从句的内容为真理或客观事实时，
须用一般现在时。

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、who、whom、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)、how (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)、whoever (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) you should turn to the teacher for help.
我认为你应该向老师寻求帮助。
My decision is that all of us are to start at 6 o'clock tomorrow morning.
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 most important to her, she told 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or not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

5 invasive colonizer species. “Golf courses are tough environments, and 6 (create) them, the vegetation
used is usually non-native. That’s 7 it doesn’t have any value for our local fish and wildlife.” the local
conservationists explained. They suggested undoing the golf course before they could restore the landscape.
8 big the job was, it offered the non-profit conservation group a tremendous opportunity to connect
two of existing properties into a single, 1,900-acre paradise (乐园) for fish, birds, and native plants. The 9
