if it ( ) tomorrow,I will go there by car

1.答案：C.
2.翻译：如果明天下雨,我将开车去那里.
3.
1）if引导的条件状语从句,如果动作都没有发生(tomorrow)的话,则严格按照“主将从现”原则,即从句使用一般现在时,而主句使用一般将来时.
2）该题恰恰是上述情况,主句I will go there by car为一般将来时,所以从句必须用一般现在时.而且从句的主语it是第三人称单数,所以be动词用is.
3）答案A为现在进行时；B没有使用动词的三单形式；D为一般将来时,全部排除.
4）另注：如果使用虚拟语气的话,则句子必须是：
If it rained tomorrow,I would go there by car.
= If it were to rain tomorrow,I would go there by car.
= If it should rain tomorrow,I would go there by car.
