whether/if引导的宾语从句

英语中的从句—名词性从句
名词性从句定性
名词性从句顾名思义在句子中起到名词成为的一部分句 子。名词在句子中可以担任主、宾、表、同位语。 在一个句子中从句占据的位置不同就是不同从句，比如 占据主语的位置就是主语从句，占据了宾语就是宾语从 句。
英语中的从句—名词性从句
引导名词性从句的关联词 从属连词 that\ whether \if\as\as if（只有连接的 功能，不充当语法成分） 连接代指词who、whom、which、what、 whose和wh+ever 连接副词where、when、why、how
如何使用关系代词和关系副词 1、看句子中的谓语动词。VT（及物动词）后无宾语，就必须用关系代词，不及物动 词若缺少介词，则必须用关系副词。 e.g. This is the town where i stayed before.
This is the town at which i stayed before. This is the town which i visited before. 2、看先行词在后面的从句子中做什么成分，来选择正确的关系词。如果先行词在后 面的从句中缺少定冠词，还需在关系词前补足定冠词。 e.g. Is this the museum which you visited yesterday. Is this museum the one you visited yesterday. This is the museum where i went yesterday
The fact surprised us.

语法精讲(十) 名词性从句
语法精讲(十)名词性从句考情分析扬帆起程的导航灯在近五年的江苏高考单项填空中，2015、2016和2017年都考查到名词性从句，分别涉及到主语从句和宾语从句，因此可把名词性从句归为高考的重点知识。
考生对于名词性从句这一块知识的失分最主要的原因在于对名词性从句的连接词掌握得不好，名词性从句的功能相当于名词词组，它在句中有不同的语法功能，一方面考生很容易选错连接词，另外对上下文语境理解有误也会导致考生错选连接词。
在选择题中连接词一般都是that，which，why，where等，但具体选用哪个连接词则取决于我们对这个句子的理解，以及关联词在这个句子里所作的语法成分。
考点聚焦疑难点津的北斗星考点1 宾语从句宾语从句：在主从复合句中，作及物动词、介词、形容词宾语的从句叫宾语从句。
引导宾语从句的关联词有：连词that，whether，if; 连接代词who，whose，what，which; 连接副词when，where，why，how等。
复习宾语从句时应特别注意以下问题：1．引导宾语从句的连接词that在从句中不作任何成分，一般可以省略，但是及物动词后跟两个(或两个以上)that连接的宾语从句时，只有第一个宾语从句中的that可以省略，其余的均不能省略。
We must believe (that) each one of us is able to do something well, and that, when we discovered what this is, we must work hard at it until we succeed.2．除except和in外，that从句一般不作介词的宾语。
(in that 有时也可以理解为从属连词，连接原因状语从句，意思为“因为”，相当于because)His report is correct except that some details are omitted.Theory is valuable in that it can provide a direction for practice.3．that从句作宾语时，还要注意一个否定转移的问题。

九年级英语 名词性从句重点和解题方法
九年级英语名词性从句重点和解题方法一、初中英语名词性从句1．_____Macao has achieved shows _____"one country, two systems" principle is the best solution to the Macao and Hongkong question, left by history.A. That; whatB. What; thatC. What; whatD. That; that【答案】 B【解析】【分析】句意：澳门取得的成就表明，“一国两制”原则是解决历史遗留下来的澳门和香港问题的最好办法。

再分析句子可知，shows后接宾语从句，从句句意和结构完成，所以第二个空应填连接词that。
故选B。
