题目
题型:不详难度:来源:
Without the ‘ greenhouse effect’, the earth ____ be about thirty-three degrees Celsius cooler than it is.
A.shouldB.wouldC.willD.must

答案
B
解析

试题分析:考查虚拟语气中的情态动词。本题是一个虚拟语气,条件是通过介词without(要不是…如果没有…)体现出来的,句意:要不是“温室效应”的影响,地球的温度会比现在要低30华氏度。CD两项不能用与虚拟语气。本句的would表示会;should表示应该;故B正确。
点评:在虚拟语气中要注意四个情态动词should, would, might, could都是指自己本身的意思。
