Question

Thanks to the old man’s hard work, a lot of _____ has been c？

Answer 1

C

解此题的关键词是谓语动词has，可见主语是单数意义的名词，可以先排除A、B，其次要注意该名词前面有a lot of来修饰，此时的a lot of不是指“许多”，而是相当于a large part of，后跟表示特定意义的名词the hill，意思是“这座山的多数地方”,1,Thanks to the old man’s hard work, a lot of _____ has been covered with green trees. A．the hills B．hills C．the hill D．hill
