一、should表示义务、责任、劝告、建议。
例如：
You should go to class right away.
你应该马上去上课。
二、情态动词should用于第一人称时可以表示说话人的一种谦逊、客气、委婉的语气。
例如：
I should think it would be better to try it again.
我倒是认为最好再试一试。
三、Should还可以用在if引导的条件从句，表示一件事听起来可能性很小，但也不是完全没有可能。相当于“万一”的意思。从句谓语由should加动词原形构成，主句谓语却不一定用虚拟语气。
例如：
Ask her to ring me up if you should see her.
你万一见到她，请让她给我打个电话。
四、Why(or How) + should结构表示说话人对某事不能理解，感到意外、惊异等意思。意为“竟会”。
例如：
Why should you be so late today?
你几天怎么来得这么晚？
五、“should + have + 过去分词”结构一般表示义务，表示应该做到而实际上没有做到，并包含一种埋怨、责备的口气。
例如：
She should have finished it.
她本应该完成它的。
扩展资料
比较should和ought to
1、表示“应该”，ought to表示义务或责任，语气更严重。
例如：
You ought to bring up this child.
你应该把这个孩子抚养*。
2、表示劝告、建议和命令，两个通用。
例如：
You should / ought to go to class right away.
你应该马上去上课。
3、表示客观推测，两个通用。
例如：
The doctor ought to/should be busy now.
医生现在应该很忙。
