二、知识点过关
look/get well 看起来很好/变好
look在本句中是一个感官动词，表示“看上去”，后接形容词。well在这作为形容词，只能表示身体健康的。
What’s wrong with you 你怎么了？=what’s the matter with you
类似的说法还有：What’s the trouble/ the matter with … 和Is there anything wrong with …
如：What’s the trouble/ the matter with her 她怎么了？
Is there anything wrong with your head 你的头不舒服吗？
I have a toothache. 我牙痛。
表达病情：sb. + have/has+病种.
have a toothache have a backache have a stomachache
have a headache have a cold have a fever
have a cough have the flu
注意：have the flu 中的定冠词the的运用。
I’m sorry to hear that. 听到那件事，我感到很难过。
“I’m sorry+动词不定式”或“I’m sorry +that从句”，是对所做错事的一种歉意或听到不好消息时的一种委婉表达。
如： I’m sorry to be late. 对不起，我迟到了。
I’m sorry （that） you are ill. 你生病了我感到很难过。
5.suggest意为“建议,提议”在此接了一个that引导的宾语从句。需要注意的是，suggest后的宾语从句要用should+动词原形，should可省略。
eg: Betty suggests that Kangkang should see a dentist." 贝蒂建议凯恩去看医生。
6."Follow the doctor's advice, and you'll get well soon."
"follow"意为“遵循，听从;跟着”， 如"follow the rules"，遵守规则;
advice是不可数名词，同样表示”建议”，可用some、much、a piece of、pieces of等修饰。
e.g. Here are some pieces of advice for you
Here are some suggestions for you.
7.How long have you been like this
这句话的时态是现在完成时。结构是have (has) +动词的过去分词，表示动作从过去延续至今，常与for连用，可以how long提问。
例:- How long has Sara lived here 萨拉在这住多久了
- She has lived here for many years.她在这个住了许多年。
他已经病了三天了 (be ill)
8.You’d better take some medicine
take some medicine 服药，medicine是药的总称，是不可数名词，若要特别指“药丸、药片”类，可用pill。
拓展：take在初中英语中其他的用法。
①“take sth．／sb．to+地点”把某物／某人带到某地去，而bring是带到说话的地方来。
如： I'll take my daughter to the zoo this Sunday．
②乘／搭(交通工具) 如：You should take a bus to the park．
③花费(时间，劳力)常用于句型：It takes sb. some time to do sth．
如：It takes us one hour to do our homework every day．
④买。 如：I will take it．
⑤“做”，和名词连用，表示与该名词意义相关的动作。
如：take a walk／take photos
9.I don’t feel like eating.
feel like sth．／doing sth．=would like sth．／to do sth．=want sth．／to do sth．
想要某东西／做某事
e.g. I feel like running.
10.You should lie down and rest.
lie down 躺下， lie的现在分词为lying, 过去式为 lay
11.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
12.I’m going to try something new. 我要尝试一些新花样。
something new "一些新的事物"
something, anything, nothing等都是不定代词，当形容词修饰不定代词时，修饰词要放在这些不定代词的后面。
nothing serious 不太严重
something interesting 有趣的事
13.So I’d like ask for one week’s leave.
(1) ask for a leave 请假
(2) ask for a week’s leave 请一周的假
(3) ask for three days’ leave=ask for a three-day leave.
14.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. =Kangkang go back 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.
15.- I'm worried about my lessons.
- Don't worry about it.
be worried about和worry about都表示“为......担忧”，前者强调”状态”;后者强调”动作”，但在实际使用中，这种差别几乎会被忽略。需要注意的是，worry作为实义动词，有三单形式，为worries，其过去式为worried。而be worried about中的worried是一个形容词，表示“担忧的“。
e.g. Jim is worried about his English exam.
Jim worries about his English exam
三、语法过关
1.情态动词（1）
定义：情态动词表示说话人对某一动作或状态的态度。
特点：1）与主要动词的原形一起构成谓语；
2）不受主语人称和数的变化影响；
3）否定直接在后面加not。
1.表达建议
You’d better (not) do sth 最好(不)做某事.
You should/shouldn’t do sth 你(不 ) 应该做某事.
Shall I take you to the library
It’s best for you to do sth对你来说最好做某
2. shall的用法
（1）作助动词时，英式英语中表示将来，可与第一人称连用，但在口语中所有人称都用will。
（2）作情态动词时表征询意见，用于第一人称的疑问句中。如：
Shall I give you a hand
Shall we go shopping on this weekend
