Question

---We should stop people                 cutting down trees.

---I agree. Trees are getting now.

A. from, fewer and fewer    B. for, more and more

C. for, less and less    D. from, more and more

Answer

A

【解析】句意：-我们应该阻止人们砍倒树木。-我同意你的说法；树木现在变得越来越少了。from来自；for为了；fewer and fewer越来越少；more and more越来越多；less and less越来越少。第一个空是固定短语stop sb. from doing sth.阻止某人做某事。根据句意可知，因为cutting down trees，树木应变得越来越少，故应选A。
