①More and more does it seem that putting yourself on display is what it is all about, which there is nothing more to love and friendship than being mutually visible. 问:这题把which改成that，与前面的that从句并列做表语从句，但是为什么两个that从句中间没有连词and呢？老师可以分析一下这句话的结构吗 ②The 42％ of Americans who have at least one step-relative typically feel a stronger sense of obligation to their biological parent,child or sibling than their step-relatives. 问:这题在than后面加上to，than后面省略的部分怎么还原呢？是省略了they feel a sense of obligation吗，那than在这个句子里充当什么成分呢？好像就没有做成分了。但是than引导比较状语从句的时候不是一定要充当成分吗？做题的时候可不可以直接把than理解成介词，不去深入思考省略的成分呢。 ③It (poetry)provided them with narratives that entertained and inspired. 问: 请问这个句子是否有误，that引导的是定语从句吗，为什么entertain和inspire后面没有跟宾语，它们不是及物动词吗？(答案并没有改动这句话) ④In mobile phone dermatitis,the rash would typically occur on the check or ear,depending on the metal part of the phone comes into contact with the skin. 问:请问这句话可以把comes改成came，理解成"came into contact with the skin"过去分词短语做"the mental part of the phone "的后置定语吗？(答案在depending on的后面加上了where)
