It is + adj + that从句,什么时候不用虚拟
It is + adj + that这个句子只是一种陈述,而不是建议、愿望、请求、命令时候不需要使用虚拟语气。
在形如“It is (was)+形容词(或过去分词)+that……”结构中,使用某些表示愿望、建议、请求、命令、可能、适当、较好、迫切、紧近、重要等形容词后的主语从句的谓语也用虚拟语气.其表达形式为should +动词原形或省略should直接用动词原形(美国英语中省去should)、
例句:It is necessary that we (should 可省略)have a walk now.(necessary,should + have) (表示有需要去散步)。
翻译:让我们现在去散个步吧。

that的其他用处:
1、that 用作指示代词(复数形式是those),其指代意义同形容词用法,同时它还可以用作定语从句中的先行词;还可为了避免重复,代替前述名词。
例句:That is what he told me.
翻译:正是他告诉的我这件事情。
2、that 用作关系代词,引导限制性定语从句。先行词可人可物,用法相当于who或which。(但是在下列情况下多用that:先行词既有人又有物时;先行词有形容词最高级、序数词、不定代词、very,only等修饰时;先行词是不定代词时)
例句:He talked about the teachers and schools that he had visited.
翻译 :他谈到了他参观过的老师和学校。
