D 解析：这是Molly与Peter讨论如何进行垃圾分类的对话场景。 1. 此处是Molly和Peter针对报纸上关于垃圾分类的文章展开讨论。从句义可知，两人对该做法都比较赞同。Molly用“That would be great!”来表达赞同，作为附议，E项“That is really a great advice”比较符合题意。 2. Molly提到了垃圾分类的好处，Peter要求Molly举例说明，Molly举完一例后，从下一轮对话来看，Peter还要求更多的例子，因此What else比较符合题意。 3. 从上文可以看出，垃圾被重新利用是有条件的，条件便是C项Once we separate and recycle them. 4. 从下文谈到废物的回收利用可以看出，Molly非常同意Peter前面的话，因此应选I couldn't agree more. 5. 在谈完垃圾分类的好处后，Peter又谈到了一些担忧，即“If people have no idea how to sort their trash…”因此，这里应选D项，意思是“但是我有一些担忧”人文英语4
