语法与词汇35.If you plant two apple trees in one square yard of land, and the trees' productivity ______decline.
【正确答案】
A
【答案解析】本题中,A项“is bound to定会”符合题意,如:The new discovery is bound to be of great service to mankind.(这项新发现对于人类必定大有用处。)其他三项中,B项is determined to的意思是“下定决心做某事”;C项is unlikely to的意思是“不大可能”;D项is related to的意思是“与……相关”,都与题意不符。因此A项为正确答案。
