(2) demand that + (should) 。
(3) sth + be required to do (不能用demanded )

3. unfair不公平的，不公正的，不合理的

5. usual , common , ordinary 的用法
〖点拨〗三者都可用来描述每天发生的事，或被大多数人接受为正常自然的而不是新奇的事件。
usual 意为“通常的，寻常的，通例的”，用于修饰经常、固定或有一定的时间间隔重复发生的事，即 www.xuehuiba.com
有一定的规律性。
它可修饰符合自然规律的事物，也可修饰符合社会风俗或个人习惯的事物，侧重于一贯如此，遵循常规，并非新奇等含义。如：
Thunder is the usual sign of an approaching storm .
The following Thursday she went out at her usual time .
common 含有“平常，普通，常见，不足为奇”等意思，侧重于缺少显著或异常的特征，特别说明某物因司空见惯而普通。如：
Colds are common in winter .
A dog is one of the commonest pets .
This flower is common in spring .
ordinary 意为“正常的，通常的，平常的，普通的”，指由于与常规、习惯、一般标准或品质相同而普通，无特别惊人的性质。如：
He is an ordinary - looking man .
It was an early morning in summer . In the streets , sleepy - eyed people were moving quickly , heading towards their jobs . This was the beginning of another ordinary day in New York City . 一大早睡眼惺惺的人们匆匆赶路，前去上班，没有任何异常的迹象，这又是纽约城一个平常的日子的开始。
6. while
while 可以用作连词，也可以用作名词。
1) while 作为从属连词，意为 “ 当……时候 ” 时，相当于 when 引导一个时间状语从句。从句中的谓语动词通常是持续性动词。例如：
He can still breathe while his head is under water .
While ( we were ) walking along the river , we saw fish swimming about
in the water .
2) while 作为等立连词，连接两个并列分句时，这两个分句在意义上形成鲜明的正
反对比。这时 while 的意义近似于 but 。例如：
Jim is lazy while his sister is diligent .
We were busy here and there , while he had nothing to do .
Some products sell well , while others don\'t . 有些产品很畅销，而其它产品却卖不出去。
3) while 作为从属连词，引导让步状语从句，这时 while 的意义相当于 though 。
例如：
While (＝Though ) she respected the manager , she didn\'t like him .
While the operation on him was successful , he couldn\'t get back to the former state of health . 4) while 作为名词，可以表示 ( 一段 ) 时间。例如：
Please wait a while . ( a while ＝ a moment; a minute ) 请等一会。
The test will be carried out in a little while . ( a little while ＝ a short time )
I haven\'t seen you for a long while . ( for a long while ＝ for a long time )
