问题描述：
It is important that enough time _____A_ to study.
A. be given B. will give C. was given D. can be given
请高手讲下,这道题为什么要选A,麻烦把4个选项都详细的讲下,谢谢!我将感激不尽!
答
因为时间是被给予,所以用被动!Will是将来时,Was是过去时,很明显本题应用一般现在时,所以是A"BeGiven"
答
这是虚拟语气特殊形式之一:
It is＋good(应该的),wrong(不当的),important(重要的),necessary(必须的)＋that＋主语＋should＋原形动词,should可以省略.
