3. 连接副词：when, where, why, how 引导从句时，它 们本身有词义，既起连接从句的作用，又在从句中 充当状语成分，修饰谓语动词。 Eg. That is where Lu Xun used to live. 那里是鲁迅曾经居住的地方。 That is why he didn’t pass the exam.

同位语从句和定语从句的区别

意义上：同位语从句对名词加以补充说明，后者对名词进 行修饰和限定 结构上： 前者连接词句子中不担任任何成分，后者由关系 词引导，关系词在从句中担任一定成分。 The idea that one can do the work without thinking is wrong.(同位语从句，that 在句子中不担任成分） The idea that you put forward at the meeting is wrong.(定语从句，that在从句中担任宾语）

同位语从句

We’ve just heard a warning on the rits way. The question came up at the meeting whether we had enough money for our research. A new idea occurred to him that it could be done in a very simple way. 同位语从句有时不是紧跟在有关的名词后面，而是被其他 的词隔开了.
那是他没有通过考试的原因。
4. 用because，as ，as if /as though 引导，如：
Eg. It looks as if it were going to rain.
看起来要下雨了。 It‘s just because he doesn’t know her. 这仅仅是因为他不认识她。 Things are not always as they seem to be.
