楼上的句子到处都是语法错误.要改你的句子都要写一大篇了.干脆只告诉你正确的句子吧: It was Lily who came up with the idea that people should drink more soft drink. 这里,idea和that people should drink more soft drink是等同的,所以that people should drink more soft drink是个同位语从句.注意idea不是楼上所说的主语.这句话的主语是It. 略微把上句改一下,就可以造出一个主语的同位语来: Lily, the girl who came up with the idea that people should drink more soft drink, is in my class. 这样,the girl就是Lily的同位语.后面的who came up with the idea是定语从句.而that people should drink more soft drink仍然是idea的同位语. 记住同位语和它所修饰的词是完全等价的.再给你一些例子: My sister Helen will come with us. Helen是同位语,修饰my sister. The news that he died shocked everyone. that he died是同位语从句,修饰the news.

同位语有两种含义:
初级的同位语就是名词或短语,例如:
Sarah, my friend, likes going swimming every Sunday.
my friend 就是 Sarah 的同位语,表示Sarah本人。Sarah是主语,如果去掉Sarah,my friend完全可以担任本句的主语。
进阶版的同位语就是一个句子,带有这种句子的就是同位语从句,例如:
The news that we are having a holiday tomorrow is not true.
that we are having a holiday tomorrow 是本句 The news 的同位语,表达的是news的内容。The news 在本句中担任主语,如果去掉The news,that we are having a holiday tomorrow完全可以担任本句主语。只不过,原句的语法类型我们称之为同位语从句,而去掉The news的句子语法类型,就变成了主语从句。

当两个指同一人或事物的句子成分放在同等位置时,若其中一个句子成分是用于说明或解释另一个句子成分的,那么用于起说明或解释作用的句子成分就叫做另一成分的同位语。(PS:句子中指代同一事物的两个词、片语或子句,称同位关系。一般跟在某些名词后面。后一成分通常叫做前一成分的同位语。)例句:Mr Wang, my child’s teacher, will be visiting us on Tuesday.王先生,我孩子的老师,星期二要来看我们。解释例句:Mr Wang 和 my child’s teacher 都是同一个人,也就是同一成分了,而 my child’s teacher 起到了解释说明Mr Wang是谁的作用,所以这个句子的同位语就是 my child’s teacher 再一例句:My sister, Helen Wilson, will travel with me.解释:句中My sister和Helen Wilson指的是同一个人,它们是同位成分,后一成分就叫做前一成分的同位语。
