The question is 5_he did the experiment. It is quite simple. He allowed a beam of light to pass through a piece of triangular(三角形) glas

6、句,但下列情况只能用whether:引导主语从句、表语从句、同位语从句时;位于句首时;后紧跟or not时;作某些及物动词(如discuss、decide、argue等词)的宾语时;与不定式连用时;作介词的宾语时。因此,若if与whether同时出现在选项中,当表示“是否”之意时,一般情况下舍if选whether。wh-与wh-ever的区别（见考题4，5）wh-ever引导宾语从句时,含有“无论”之意,其引导宾语从句时无疑问意义,而wh-多有疑问之意。no matter + wh-与wh-ever的区别（见考题6，7）no matter + wh-只能引导状语从句;而wh-ever既可引导状
7、语从句,也可引导名词性从句。主语从句与非限定性定语从句（见考题8）主语从句指从句在复合句中充当主语，是主句谓语动词的动作发出者。在形式上，非限定性定语从句与主句之间用逗号隔开。它对其先行词没有限定、修饰的作用，只起补充说明的作用。同位语从句和定语从句前者是对前面的某一名词进行解释说明；后者一般是对某一名词进行修饰限定。注意：that作为关系代词，可以引导定语从句，充当句子成分，在从句中作宾语时可以省略；that引导同位语从句时，起连词的作用，没有实际意义，不充当句子成分，一般不能省略。例如： I had no idea that you were here 【解析】这句话的意思是：“我不知道你
8、在这里。”That引导同位语从句，不能省略。 Have you got the idea (that) this book reveals of life in ancient Greece? 【解析】这句话的意思是：“你获得这本书所透露的关于在古希腊生活的信息了吗？”That引导定语从句，指代the idea,作reveal的宾语，可以省略。四、名词性从句需要关注的考点：易考点说明It作形式主语(见考题1)It作形式主语的常见结构：(1) It + be +形容词（necessary/important/obvious）+ that从句。 (2) It + be + 过去分词(believe
9、d/reported/ decided) + that从句。 (3) It + be +名词+ that从句。例如:It is common knowledge that . (是常识);It is a surprise that . (令人惊奇的是);It is a fact that . (事实是)等。 (4) It +不及物动词+ that从句。例如:It appears that . (似乎); It happens that . (碰巧);It occurred to me that . (我突然想起)等。 It作形式宾语(见考题2,3)It作形式宾语的常见结构:(1)宾语从句+宾语
10、补足语。常见的用it作形式宾语的谓语动词有believe、find、make、guess、suppose等,具体形式为believe / find / make / guess / suppose it +宾语补足语(一般为形容词)。 (2)某些及物动词或短语不能直接加宾语从句,此时用it作形式宾语,然后再接宾语从句,此种用法常见于like、dislike、hate、appreciate等谓语动词后。 that的省略 (见考题4,5)一般来讲，在主语从句、表语从句和同位语从句中的that不可省略。而在宾语从句中的that可以省略，但下列情况一般不省略：当一个句子有两个或多个并列的宾语从句时，引
11、导第二个和以后几个从句的that不可省略；由it作形式宾语时；当宾语从句是双宾语中的直接宾语时；当宾语从句的主语是非谓语动词或从句时；当主句的谓语动词与宾语从句之间有插入语时；当that宾语从句中的状语从句位于该从句的前部时。 从句与先行词的分隔(见考题6)这种情况多见于同位语从句。为了保持句子平衡，从句与先行词往往被介词短语、副词或谓语等分开。 从句语序(见考题7)1.名词性从句永远是陈述句的形式：S+V+疑问词+S+V。2.此种句型称为间接问句，常接于ask，tell，doubt, wonder等动词后。五、【基础训练】（一）、判断下列各句哪句含有名词性从句，并指出是什么从句：1.
