第三、由when引导的同位语从句

我不知道他什么时候回来
有时可用namely(即),that is to say(也就是说),in other words(换句话说),that is(那就是),for example等引出同位语,说明其前面的名词(或代词)

要注意同位语从句和定语从句的用法的区别
同位语从句其形式与定语从句相似,二者之前都有先行词,但与先行词的关系不同:同位语从句与先行词同位或等同,是对名词加以补充说明,定语从句则与先行词是修饰关系,试比较
The news that they had won the game soon spread over the whole school.
他们比赛获胜的消息很快传播了全校(同位语从句)
The news you told me yesterday was really disappointing.
你昨天告诉我的那个消息实在是令人失望(定语从句)
同位语从句一般紧跟其先行词之后,但有时也可与先行词分开,置于句末,如:
The suggestion came from the chairman that the new rule be adopted.
采纳新规则的建议是主席提出来的
