27 that引導(dǎo)定語從句和同位語從句時(shí)的區(qū)別 Track 027
（1）that是否作成分
that在定語從句中充當(dāng)成分，而在同位語從句中不作任何成分，僅起連接作用。
a. The rumor that he spread everywhere turned out to be untrue.
b. The rumor that Tom was a thief turned out to be untrue.
以上兩句先行詞都是the rumor，引導(dǎo)詞都是that。但a句中的that在從句he spread everywhere中作spread的賓語。故a句中that引導(dǎo)的是定語從句。b句中的that在從句Tom was a thief中不作任何成分，故b句中that引導(dǎo)的是同位語從句，作the rumor的同位語，補(bǔ)充說明the rumor的具體內(nèi)容。
c. The fact that we talked about is very important. （that作 talk about的賓語，定語從句）
d. The fact that he succeeded in the experiment pleased everybody. （that不充當(dāng)成分，同位語從句）
（2）從句的作用
定語從句相當(dāng)于形容詞，它對(duì)先行詞起修飾、描述、限制的作用；同位語從句相當(dāng)于一個(gè)名詞，它是前面名詞的內(nèi)容的具體表述，與前面名詞是同位關(guān)系。
a. The news that you heard is not true. （定語從句）
b. The news that Lincoln was murdered at a theatre is true. （同位語從句）
c. The fact which you pointed out made me interested. （定語從句）
d. The fact that there are no lives on the moon is known to us all. （同位語從句）
