在复合句中，担任主语的从句叫主语从句。引导主语从句的词有：连词that, whether；连接代词wh, what, which；连接副词when, where, why, hw等。一、由连词that, whether引导的主语从句       1. that引导主语从句时，无实际意义，只起连接作用，不充当任何句子成分，当它引导的主语从句置于句首时，that不能省略。       2. whether意为是否，不可以省略。
二、由连接代词wh, what, which引导的主语从句       连接代词wh, what, which引导主语从句时，在从句中充当主语、宾语或定语等。三、由连接副词when, where, why, hw引导的主语从句       连接副词when, where, why, hw引导主语从句时，在从句中充当状语。
当主语较长时，常用it作形式主语，而将主语从句放在句末。如：It is knwn t all that light travels in straight lines.常见的由it作形式主语的句型如下：①It + be +名词+从句。常用于此句型的名词有：fact, rule, pleasure, truth, pity, mystery等。如： It is a fact that English is being accepted as an internatinal language.
②It + be +形容词+从句。常用于此句型的形容词有：true, imprtant, strange, necessary, clear, certain等。如： It is true that the earth is rund.③It +动词+从句。常用于此句型的动词有：seem, appear, happen, fllw等。如： It seems that yu're right.④It + be +过去分词+从句。常用于此句型的过去分词有：knwn, said, prved, reprted, suggested等。如： Is it knwn where he went?
注意：1. that引导的主语从句置于句首时，that不能省略。但是如果用it作形式主语，而把主语从句放在句末时，that可以省略。如： That yur pictures shuld surprise them was quite natural. It was quite natural (that) yur pictures shuld surprise them.2. 如果主语从句置于句首，则不能用if引导，而用whether。但如果用it作形式主语，而把主语从句放在句末时，也可以用if引导。如： Whether Tm really saw Sharn was dubtful.  It was dubtful whether / if Tm really saw Sharn.
用适当的连接词填空。       It is knwn 1. ________ hmewrk is an imprtant part f schl life in mst cuntries arund the wrld. Hwever, 2. ________ hmewrk has a great educatinal value is still a debate amng teachers.
