选择题
It is quite impossible that it will rain tomorrow. But if it __________, I would still go to school by bike.
A．should rain
B．would rain
C．rains
D．had rained
答案
答案：A
题目分析：句意：明天不可能下雨，但是如果下雨，我依然骑车去学校。表示与将来事实相反，条件状语从句中的谓语动词一般过去时或should(were to) + 动词原形，而主句中的谓语动词则用would / should/could might + 动词原形。可知选A。
