①简单句有且只有一个谓语动词
②expect已经是谓语动词了,所以后面的只能用非谓语动词(非限定动词)hoping
③如果硬要用hope,那就加and,改成并列句:
As we all know, most Chinese parents expect too much from their children and hope(that) they will stand out and be admitted into a famous university when they graduate.
④至于hoping...作什么成分。简单说,作该分句的谓语。而“parents”是该分句的逻辑主语。
这里注意,要区分谓语和谓语动词。谓语动词只是谓语的一部分
