情态动词should的用法
情态动词should和can ，may ，must一样，没有人称和数的变化，有词意，但都不能单独作谓语，必须和后面的动词原形一起构成谓语。

基本意思是“应当，应该”，常用来表示建议或命令等。

如：You should work harder. 你应该更努力地工作。

否定式和疑问式的构成与can ，may ，must一样。

如：
You shouldn’t play soccer in the stre et. 你们不应该在街上踢足球。

Who should pay the taxi driver? 谁应该付出租车钱？
注意：
常用句型You should /shouldn’t do sth. 表示“建议某人（不）做某事”。

其他表示“建议”的句型还有：Why not do sth.? /Why don’t you do sth.? /How about doing sth.? /What about doing sth.? /It’s a good idea to do st h. /You’d better do sth.等。

should作为情态动词用，常常表示意外、惊奇、不能理解等，有“竟会”的意思，例如：
How should I know? 我怎么知道？
Why should you be so late today? 你今天为什么来得这么晚？
should有时表示应当做或发生的事，例如：
We should help each other.我们应当互相帮助。

我们在使用时要注意以下几点：
1. 用于表示“应该”或“不应该”的概念。

此时常指长辈教导或责备晚辈。

例如：
You should be here with clean hands. 你应该把手洗干净了再来。

2. 用于提出意见劝导别人。

例如：
You should go to the doctor if you feel ill. 如果你感觉不舒服，你最好去看医生。

3. 用于表示可能性。

should的这一用法是考试中常常出现的考点之一。

例
如：
We should arrive by supper time. 我们在晚饭前就能到了。

She should be here any moment. 她随时都可能来。
