同步知识点讲义和练习
一、重、难点
1. What’s wrong with you ? 你怎么了？
用于询问病情或别人不高兴的原因。
同义句有：What’s the matter/ trouble with you ? (matter/ trouble 是名词，前用the ；wrong 是形容词，前不用the )
What’s wrong with her?她怎么了？
Is anything wrong with your head？你的头不舒服吗?
2. have后面跟表示疾病的词，表示“得了……病”。
have a cold=catch a cold患感冒；have a cough 患咳嗽；have a fever 发烧；
have a stomachache 胃疼；have a headache 头痛
have the flu 患流感；have sore eyes 眼疼 (注意这两个特殊点的)
（1）ache 指持续的疼痛
head-headache 头痛 stomach- stomachache 胃疼back-bachache 背疼
Eg：I have a headache. = I have an ache in my head.
（2）sore常指发炎而引起的肌肉痛
foot-sore foot 脚痛 back-sore back 背痛 arm-sore arm 胳膊痛
（3）pain 指肉体上的剧烈疼痛
Eg：I have a pain in my head.=I have a headache.我头痛。
注意：have the flu 患流感
have表示“吃”时，have breakfast/supper/dinner/lunch，中间不能有冠词，但have后面的名词有形容词修饰时，可加冠词。have a big dinner.吃一顿丰盛的正餐。
3. You look pale.
系动词有：be是；look看起来, smell闻起来, sound听起来, taste尝起来, feel觉得，turn/get/become 变；他们后常接形容词作表语， 系动词常可用动词be 来替换。如：
The music sounds wonderful. = The music is wonderful.
You look young.=You are young.
4．I don’t feel like eating.
feel like “想要”，后面通常跟名词、代词、动名词。
如: I feel like running.
近义词组 want to do sth./would like to do sth.
I want to take these books to the classroom.
I would like to eat some hot dogs.
5. You’d better not eat too much candy.
(1) too much 修饰不可数名词，还可以用来修饰动词，如：
①too much money; ② Stay in bed and don’t move your leg too much.
(2) too many 修饰可数名词复数，如：too many students
(3) much too修饰形容词或副词,如：much too expensive
6. Let me check it over .
check over = look over 检查正误，检查身体 如：
①Can you check over my homework.
②The doctor checked her over and she was fine.
7. So I’d like ask for a week’s leave.
(1) ask for a leave 请假 (2) ask for a week’s leave 请一周的假 (3) ask three days’ leave=ask a three-day leave
如：We can only take a three-day leave.= We can only take three days’ leave.
8. I hope I’ll get well and return to school soon.
(1) return to +某地= go/ come back to… 表返回某地，如：Kangkang returned to Beijing.
(2) return sth. to sb. = give back sth. to sb.表归还某物给某人，如：
You must return it to me soon. = You must give it back to me soon.
9. I couldn’t read it until today.
否定句+ until．．．　表不能做某事，直到什么时候才能做。　如:
I can’t help you until you tell me the truth. 我不能帮助你，直到你告诉我真相我才帮你。
You can’t watch TV until you finish your homework. 你不能看电视，直到你做完作业。
10. My sister is also sick.
Sick和ill 都表“病的“，但sick 即可以作定语也可以作表语，如：①a sick girl; ②The girl is sick. 而ill只能作表语，如：The girl is ill.
重点短语：
take a rest = have a rest 休息一下
take some medicine = have some medicine 服药
day and night 日日夜夜
lie down 躺下
brush one’s teeth 刷牙 （tooth的复数teeth）
have an accident 发生一场事故
stay in bed 待在床上
plenty of = a lot of 许多的；大量的, 可接可数名词的复数或不可数名词
worry about sth./ sb. 为… 担心
二、语法精讲
情态动词（helping verbs）本身有一定的词义，但是不能独立作谓语，只能和行为动词一起构成谓语。情态动词用在行为动词前，表示说话人对这一动作或状态的看法或主观设想。 情态动词虽然数量不多，但用途广泛，主要有下列： can (could), may (might), must, need, ought to, dare (dared), shall (should), will (would) must not.情态动词的位置: 情态动词在句中放在谓语动词之前 ,疑问句中, 情态动词则在主语之前。
情态动词的特点: 情态动词无人称和数的变化, 情态动词后面跟的动词需用原形,否定式构成是在情态动词后面加 "not"。 个别情态动词有现在式和过去式两种形式, 过去式用来表达更加客气, 委婉的语气, 时态性不强, 可用于过去，现在或将来。
(一)Should
1.通常用来表示劝告和建议，译作“应该”、“应当”， 没有人称和数的变化，否定形式为should not ，通常简写为shouldn’t，例如：
You should complete your test in time. 你们应该按时做完你们的实验。
You should tell your mother about it at once. 你应该立即把此事告诉你妈妈。
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。
You shouldn’t talk in class. 你不应该在课堂上说话。
我们在使用时要注意：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.用于第一人称疑问句中询问对方的意愿，但语气较委婉温和。
What should we do now? 我们现在应该做什么？
Should I open the window?我能打开窗户吗？
3.表示推测、可能。
He should be in the classroom.他应该在教室。
This pen should be yours.这支笔应该是你的。
4.表示说话人的感情，如惊奇、愤怒、失望等。
Why should I go?为什么我应该去？（表示不满）
— Where is Betty living? — 贝蒂住在哪里？
— How should I know? — 我怎么会知道呢？
I don't know why you should think that I did it. 我真不知道你凭什么认为这件事是我干的。
（二）had better
常简略为'd better, 是一_??????è?????_，had better"最好"，用于表示对别人的劝告、建议或表示一种愿望。其用法有以下几点:
_had_better_后面必须跟动词原形，构成had better do sth.句型。 这里的had不能用have来替换。如:
You'd better go to hospital at once.你最好立即去医院看病。
Tom, you'd better go there today.汤姆，你最好今天去那儿。
主语不论是第几人称，句子不论是什么时态，都要用had better的形式。如:
Now you(he，we) had better listen to the teacher.你(他，我们)现在最好听老师讲。
had better的否定式。常用的否定形式是将否定副词not直接放在had better的后面。如:
You had better not miss the last bus.你最好不要错过末班公共汽车。
You had better not leave for Nanjing the day after tomorrow.你最好后天不要动身去南京。
注意:否定副词not绝不能放在had的后面。如:不能说:You hadn't better go.而应该说:You had better not go.
had better在表示对别人劝告、建议时，不宜用于与陌生人、长辈及上级的交谈中。 对长辈说话时，最好不用had better。比较有礼貌的说法是:It might be better for you...; It would be better for you...。如:
It might be better for you to help me，Grandpa.爷爷，您最好能帮我一下。
[练习] 下列各句都有一处错误，请改正。
1.You'd better to wait for me at the school gate.
2.I have better write to him now. 3.You had not better go there.
参考答案:1.去掉to。2.have应改为had。3.将not置于better后面。
