题目
题型:不详难度:来源:
By the middle of the 21st century, the vast majority of the world’s population _____ in cities rather than in the country.
A.are living B.will be living C.have livedD.will have lived

答案
B
解析

试题分析:考查时态。根据本句的时间状语by the middle of the 21st century说明是一个将来时。陈述的是在将来的这段时间里所发生的事情,所以使用将来进行时。句意:到21世纪中叶,大部分的人口都将生活在城里而不是在乡下。故B正确。
点评:时态题的考查关键是抓住句中的时间状语。要根据时间状语来选择合适的时态,在平时的学习中要注意积累有关时态的用法和各种时态的特殊之处。
