Question

Without the air to hold some of the sun’s heat,the earth at night　　　.

A．would be freezing cold	B．will be freezing coldly
C．would be frozen cold	D．can freeze coldly

Answer 1

A

句中介词短语“Without the air to hold some of the sun’s heat”暗示条件，实际上相当于一个明确的条件状语从句If there were no air to hold....根据句意及句中时间状语today可知句子是对现在情况的假设，所以该句应用与现在事实相反的虚拟语气。
