情态动词should的用法
1. should在肯定句中可用来讨论义务和职责或提出建议，意为“应该”。如：
You should pay more attention to spelling.
2. should后面跟不带to的动词不定式。否定式should not，其缩略形式是shouldn’t，意为“不应该 ”。如:
You should not / shouldn’t play football in the street.
Summary
3. should 用于疑问句，表示征求意见或请求指示。 如：
— Should I call the police
— Yes, you should. / No, you shouldn’t.
4. should 还可以表示更正别人的说法。
— The total price of these books is 230.5 yuan.
—No. That should be 232.5 yuan. Check it again.
注意：should和ought to均可用来谈论义务和职责或提出建议。两者 可以互换使用，不过should常用得多。
Summary
had better 用来表示竭力劝告，或告诉人们(包括自己)该做什 么事，意为“做……是好的；最好还是”。
had better之后要用不带to的动词不定式，即：had better do，
其缩略形式为 ’d better。
通常用“had better not + 不带to 的动词不定式”来表示否定。 如：
We’d better hurry or we will miss the train.
You’d better not go out late at night.
had better的用法
Summary
用于回答时，通常用简略式。如：
— Shall I wash my clothes right now
— You’d better. / You’d better not.
注意：
1. had better通常并不表示所提出的建议比其他选择更好——这里没有比较的意思。
2. had better用于谈论最近的将来，比should或ought to在时间上更为紧急。如：
There is only five minutes left. You had better hurry up.
只剩五分钟了。你还是快点吧。

板书 Unit 8 Grammar一、should的基本用法及句型肯定句sb should do sth ...否定句sb should not / shouldn’t dosth ... (should not = shouldn’t一般疑问句Should sb do sth ... 简略答句Yes, sb should.No, sb should not / shouldn’t.注意：should 没有人称、时态和数的变化，后接动词原形。二、should与ought to 的区别大体上两者的意思是相同的，通常可以互相转换，但也有以下的细微区别。shouldought to区别强调主观看法，有“劝告；建议”的意思，即“按我的想法该如何”，语气比较委婉。表示提一些建议、劝说时，译作“应当”。比should 语气强，更多地反映客观情况，表示“有义务”或“必要”做某事，更多是在谈到法律、义务和规定时使用；有时带有责备或督促的意思，译作“应当；应该”。例如：You really should take more exercise.你真的应该多运动。She is your mother. You ought to take care of her when she gets old.她是你的妈妈。当她老了的时候你有义务照顾她。B. had betterhad better（常简略为’d better）是一个固定词组，意为“最好”，用于表示对别人的劝告、建议或表示一种愿望。其用法需要注意以下几点：一、had better后接动词原形had better 后接动词原形，构成句型had better do sth“最好做某事”。这里的had 不能用have或has来替换。例：You’d better go to hospital at once.你最好立即去医院。二、had better 不随时态的变化而改变形式，可用于各种人称。例如：三、had better 的否定式：将否定词not 直接放在had better 的后面，构成句型had better not do sth“最好不要做某事”。例：You had better not miss the last bus.你最好不要错过末班车。注意：在陈述句中，否定词not 绝不能放在had的后面，即不能说：You hadn’t better go. 而应该说：You had better not go.
