问题 Without the air holding in some of the sun’s heat, the earth______cold at night, too cold for us to live on.

选项 A、will be freezing
B、would be freezing
C、can be frozen
D、would be frozen

答案 B

解析如果不是空气保留了部分太阳的热量，夜晚的地球将会非常冷，以至于我们无法生存。本句考查虚拟语气的一般现在时，从句由without引导，主句应使用will的过去式would。frozen冻结的。freezing cold非常寒冷。
