必须是原型，或者是should be/should do,总之 考试的话一般是考原型，它是虚拟语气的一种。固定的。

下面的你可以看看，也可以不看。很少跟时态一般现在时，当然，如果不是考试，平常用也没有那么讲究。

在It is imperative(essential，necessary，appropnate，desirable，important，vital等)+that引导的主语从句中谓语动词应该用虚拟语气的形式，即使用动词原形或should+动词原形。例如：

1Itis vitallyimportantthatthey receive allthe help available极为重要的是他们要得到所有可能得到的帮助。(《麦克米伦高阶英汉双解词典》)

2It is important that you(should)keep your promise你应该遵守诺言，这一点很重要。(《外研社·建宏英汉多功能词典》)

3The president said it was imperative that the release of all hostag be secured总统说当前要务是确保所有人质都获释。(《剑桥高阶英汉双解词典》)

4It is essential that our prices remain competitive我们保持价格方面的竞争优势是至关重要的。(《剑桥高阶英’汉双解词典》)

5Itismostdesirablethatthey shouldboth come他们两个人都来，这最好不过了。(《牛津高阶英汉双解词典》)

6Il is desirable that you should have some familiarity with computers你应该对计算机知识有所熟悉，这是很有益处的。(《朗文当代高级英语辞典》)

7Itis advisablethattheygowithaclearlydefined goalm mind他们去时宜在思想上有一个明确的目标。(《译文·英汉大词典》)

8It is appropriate that the exhibition should besponsored by BMW这个展览会由BMW来主办是恰当的。(《外教社·柯林斯英汉双解学习词典》)

但是一个事实是：在It is necessary(essential，imperative，appropriate,desirable，important，vital等)+that引导的主语从句中谓语动词用一般现在时的情况也绝非罕见。在大家熟悉的词典里很容易找到这样的例句。例如：

1It is absolutely vital that the matter is keptsecret这件事要保密，这是至关重要的。(《牛津高阶英汉双解词典》，2002年版，p1695)

2It is absolutely imperative that these safetymeasures are implemented immediately这些安全措施必须立刻执行。(《朗文当代高级英语辞典》，外研社2004年版，p980)

3It is essential that the On is checked every10,000 km每行驶10000公里就必须检查一下润滑油。(《朗文当代高级英语辞典》，外研社2004年版，p633)

4Itis essentialthatyouare surewhatyourgoalsare你必须明白自己的目标是什么。(《麦克米伦高阶英汉双解词典》，外研社2005年版，p684)

5Itisimperativethatthese claimsaredealtwith
