---the floor and the infection （it）brought along really made the villagers suffer a lot

请问为什么要用括号里的词,而不用（they are） （how）（that）（when）
---（it is）the students from the school.
--it is none of your buiness （what）other people think about you ,believe yourself.
---the floor and the infection （it）brought along really made the villagers suffer a lot
---having checked the doors were closed,and（that）all the lights were off ,the boy opend the door to his bedroom.
请问为什么要用括号里的词,而不用（they are） （how）（that）（when）
1. --- Who is singing and dancing in the gym now?
---（It is）the students from the school.
人称代词不仅用于指代上文中提到过的无生命物体,而且还指代性别不详、不知或不相关的有生命的群体,如：
Is this your book? Yes, it is.
Who is speaking over there? It's Tom speaking. ( 电话用语)
该题中指代的就是不明的有生命的群体.
2. --- It is none of your buiness（what）other people think about you ,believe yourself.
这里的代词 what 是 think 的宾语,如果改为副词 how,必须改为 how other people think it about you, 否则句子缺少成分,不完整.
3. --- The flu and the infection （it）brought along really made the villagers suffer a lot.
这是一个主从复合句,其中：
主句——The flu and the infection really made the villagers suffer a lot.
定语从句——（that）it brought along ,关系代词 that 是从句中 brought 的宾语,因此省略.
4. --- Having checked the doors were closed,and（that）all the lights were off ,the boy opend the door to his bedroom.
本句含有现在分词短语 Having checked ...充当的时间状语,其中包括由 and 连接的两个并列的宾语从句,即：
1）Having checked the doors were closed
2）and (having checked）that all the lights were off
由于第二个从句离开动词较远,为了让人看清它也是动词 checked 的宾语从句,因此用了连接词 that.
---（It is）the students from the school.
