(4) What did the doctor tell her to do?
The students are expected to answer the questions in pairs.
Step 3. Reading
Get the students to read the dialogue for more detail information.
Step 4. Explanations to the dialogue
1. At the doctor's 在医生的诊所
在英语中， 常用从事某行业的人的所有格来表示他所工作的地方，如本课标题“At the doctor's ”就相当在 At the doctor's clinic。又如：
a baker's 面包店(a baker's shop)
a barber's 理发店(a barber's shop)
a tailor's 裁缝店、成衣店(a tailor's shop)
The Bell's 贝尔电话公司(The Bell's Telephone Company)这种名词的所有格结构还可以用来表示某人的家。例如：
at his parents'(home) 在他父母亲的家里
in her uncle's(house) 在她叔叔的住所
2. What can I do for you? 你有什么不舒服吗?
这是表示“主动提供帮助”(offer one's help)时的交际用语。本课对话是在诊所进行的，“What can I do for you?”是医生为病人提供服务时说的话， 意思就是 ：“你有什么不舒服吗?”或“你来看病吗?”。例如：
(D=Doctor; P=Patient)
D: What can I do for you? 你来看病吗?
P: Well, I've got a cough. I couldn't sleep well. 我咳嗽，睡不好觉。
D: What can I do for you, sir? 先生，你看什么病?
P: I've got a pain here. I couldn't lift my right hand. 我这儿有点痛。我的右手抬不起来。
另外，“What can I do for you?”用在不同场合， 可以有不同的译法。例如在商店里，店员对顾客说：“What can I do for you?”， 意思就是“你要买什么东西?”， 你可以回答说：“I'd like to buy …”。 如果在餐馆里， 服务员问你“ What can I do for you?”， 意思就是“你想吃/喝点什么?”， 你可以回答说“I'd like to have a hamburger.” (我想吃汉堡包。) 或“A glass of beer, please.”(请来一杯啤酒)。 如果在售票处， 售票员问你“What can I do for you?”，意思就是“你买什么票?”，你可以根据实际情况回答，如“ Two tickets to Beijing for tomorrow, please.”(请买两张明天去北京的车票。)
3. What's the matter? 你有什么不舒服?
“What's the matter (with you)?” 本意是“ (你) 怎么啦?”，用以表示关怀和焦虑。本课对话是在诊所进行的，这句话就是医生询问病情时的用语，意思是“你有什么不舒服?”。
类似的表达还有：What's wrong with you?/What's troubling
you? 例如：
D：What's the matter with you? 你有什么不舒服?
P：I coughed a great deal last night. 昨晚我咳得很厉害。
D：What's wrong with you? 你有什么不舒服?
P：I've got a headache. I feel terrible. 我头疼得很厉害。
4. It's nothing serious. 这不要紧。/没什么大问题。
这是医生在检查病人后对病人说的安慰话语。例如：
P：I don't feel well. I've got a bad headache. 我觉得不舒服，头很疼。
D：Let me examine you. 我来给你检查一下。
(A while later.)
D：Don't worry. You've got a cold. It's nothing serious, but you'd better have a good rest and drink plenty of water. Take this medicine three times a day and
you'll be well soon. 别着急。你感冒了，没有什么大问题，不过， 你得好好休息一下,多喝些水。这个药一天服三次,你很快会好起来的。
注意，修饰不定代词something、anything、nothing 等的形容词，应放在这些不定代词的后面。例如：
P：Is there anything wrong with my back? 我的背部有什么毛病吗?
D：No, nothing wrong. /I don't think it's anything serious.
没有什么问题。/我认为没有什么大问题。
5. I advise you not to eat fruit that isn't ripe, in future. 我劝你今后不要吃不熟的水果了。
(1) 劝告某人做/不做某事时，可用下列交际用语：advise sb. to do/not to do sth. 例如：
P：Is there anything wrong with my heart? 我的心脏有什么问题吗?
D：Yes, there is something wrong with your heart. I advise you not to smoke any more. 是有点问题。我劝你不要再吸烟了。
D：I advise you to take a physical examination. 我劝你做一次体格检查。
P：Do you think I really need it? 你认为我的确需要做体检吗?
D：Yes, I think so. 我认为要做。
(2) in future与in the future都表示“在将来”的意思， 一般可以互换。但前者强调“从今以后/今后”(from now on) 的意思；后者着重表示“将来某个时候/将来” ( sometime in the future) 的意思。例如：Don't do that again. Be more careful in future. 别再那样做了。今后更要注意了。
I promised him to eat less sugar in future. 我答应他(我)今后少吃糖。
More peaches will be harvested by our farm in the future.

Step 5. Language points
1. Every person needs water and a diet of healthy foods.
每个人都需要水和健康的食物。
(1) diet和food都可以作“食物”解。但前者是抽象名词， 常指“饮食”而言，或指为特殊需要而规定的食物；food 是一般用语，指具体的食物，凡是吃的喝的都属food。它通常用作不可数名词，常用单数。但在表示食物的种类时，也可用复数( 如本句中的foods)。例如：
The doctor advised him to take a special diet to lose weight.
医生劝他吃减肥的特别饮食。
The best liquid diet for the patient is milk but she doesn't like it.
最好的给病人吃的流质食物是牛奶，但她不喜欢喝。
Healthy foods include fruits, eggs, vegetables and some soft drinks.
健康食物包括水果、鸡蛋、蔬菜和软饮料。
Milk is the natural food for young babies. 牛奶是婴幼儿吃的天然食物。
(2)注意下列派生词的构词法：
名词+后缀-y→形容词
health(健康) +-y → healthy(健康的)
cloud(云) +-y → cloudy(多云的)
rain(雨) +-y→ rainy(多雨的)
salt(盐) +-y→ salty(咸的)
weight(重量) +-y→ weighty(重的)
fun(滑稽) +-y→ funny(滑稽的)
2. They eat different kinds of food which change into energy.
人们吃的各种各样的食物都能转化成能量。
短语动词 change into 作 “转变成” 解 (to become something different)。例如：
Everything she eats changes into fat. 她吃的东西都变成脂肪了。
When temperature goes down to 0℃, water changes into ice.
当温度降至0℃时，水就变成了冰。
上述例句中的change是不及物动词。change还可以作及物动词，构成“change A into B”结构，意思是“把A变成B”，可用于被动句。例如：
Do you know how to change these things into ice cream?
你知道怎样把这些东西制成冰淇淋吗?
Please change this sentence into a special question.
请把这个句子改成一个特殊疑问句。
Raise the temperature, and the ice will be changed into water.
升高温度，冰就会变成水。
3. The energy is measured in calories. 这种能量是以卡来计算的。
句中的介词短语“in calories”是“以卡(为单位)”的意思，这里的in作“以……”、“用……”解。“介词 in+ 计量单位的复数形式”表示计算或度量的标准。例如：
In Britain, the weight is generally measured in pounds.
在英国，重量通常以磅来计算。
The living space is measured in square metres.

The distance in space is told in light years. 宇宙中的距离是以光年来计算的。
4. While you are at school, or walking home, your body is burning up 100 calories an hour. (=… your body is using 100 calories an hour.)在学校读书或者走路回家的时候，你的身体每小时要消耗 100 卡的热量。
短语动词burn up原意是“烧掉”、“烧毁”，本句中转意为“用掉”“消耗掉”。例如：
Don't burn up these old books. They might be useful.
不要烧掉这些书，它们也许还有用。
The factory burned up completely last night. 昨晚那家工厂彻底地烧毁了。
Do you know how much energy you will burn up during the relay race?

5. When playing football or basketball, you might be using 400 calories an hour. (=When you are playing football or basketball, ……) 踢足球或打篮球时，你可能每小时要消耗400卡热量。
在带有时间状语从句(when-clause)的主从复合句中， 如果从句中的主语与主句中的主语相同， 则从句中的主语可以省去，而构成“when+ ing形式”的结构。例如：
When the doctor was examining me, he said,“ Nothing serious.” ＝ When examining me, the doctor said, “nothing serious.” 医生给我检查身体时说道：“没有什么大问题。”
When he was eating the peach, he found it too green to eat. ＝ When eating the peach, he found it too green to eat. 他吃桃子的时候，发现桃子太生了，不能吃。
6. On Sports Day, during the relay race, you will use most of all , perhaps as much as 650 calories an hour. 在运动会上，在接力赛中，你消耗的热量较多，每小时多达650卡。

这儿雨水很多，每年的降雨量常常多达70英寸。
As many as 240, 000 people lost their lives in a terrible earthquake in Tang Shan. 在唐山一次可怕的地震中，死亡人数多达24万。
在“as…as”结构中还可以加入其它的形容词或副词，表示“到……程度”，如“as long as(长达)，as high as(高达) ， as deep as(深达)，as early as (早在……时候)等。例如：
The building is as high as 120 metres. 那座大厦高达120米。
As early as the 19th century the English began to control Hong Kong.
早在十九世纪，英国人就开始控制香港了。
7. The Chinese diet is considered to be the healthiest in the world. (=People think that the Chinese diet is the healthiest in the world.) 中国的饮食被认为是世界上最健康的饮食。
Consider 作 “认为” 解时， 后面可跟不定式的复合结构(consider sb./sth. to be…)。 本句中的谓语动词用的是这个结构的被动式。例如：
People consider the Western diet to be unhealthy diet.＝The Western diet is considered to be unhealthy diet. 西方的饮食被认为是不健康的饮食。
Ice cream is considered to contain too much sugar. ＝People consider ice cream to contain too much sugar. 人们认为冰淇淋含糖量太高了。

亚伯拉军•林肯被认为是美国最伟大的人。
8.It (The Chinese diet) is rich in fibre and low in sugar ad fat. 中国的饮食含有很多的纤维，而糖和脂肪的含量却很少。

Coca Cola is considered to be rich in sugar. 人们认为可口可乐的含糖量很高。

一般地说，“be + adj. + in ”结构常用来表示“在……方面的特征”。例如：

9. Because of this, they put on weight very easily. (=…，they become heavier and fatter easily.) 正因为这样，他们的体重很容易增加。
(1)because of是短语介词，作“因为”解，后跟名词或代词，构成介词短语，在句中作原因状语。例如：He hasn't had anything for two days because of illness. 因为生病，他两天没吃东西了。
He eats lots of sweets. Because of this, he has bad teeth. 他吃糖吃多了，因此，牙齿不好。
(2) put on weight的意思是“增加体重”、“长胖”(become heavier and fatter)。 它的反义词组是 “lose weight”， 意思是“减少体重”、“减肥”(become lighter and thinner) 。例如：

2. Reading comprehension: ⑴skimming ⑵scanning
Key points: 1.Words and useful expressions 2. Reading comprehension
Teaching methods: Reading — explanation ---- practice
Time arrangement:
This lesson is to be finished in one teaching period.
Teaching procedures:
Step 1. Revision
(1) Check the homework exercises.

Step 5. Language points
1. Scores of people went there in the first few days after its opening. (=Lots of people went to the new restaurant……) 开张的头几天，许许多多的人去那家新餐馆吃饭。
Score n. 二十。它所构成的词组scores of/a score of 作“许多”解，相当于lots of /a lot of的意思， 但前者是书面语，后者更常用于口语中。例如：“How many people were present at the party?”——“A score or more.”
“出席聚会的人有多少?”——“二十多个。”
The owner of the shop is a man of about three score years.
那家商店的主人是一个六十来岁的男人。
Scores of Westerners came to visit the Great Wall last week.
上周有许多西方人来参观长城。
I have been to the hamburger restaurant a score of times.
我到那家汉堡包餐馆去过许多次。
2. “Not good value for money,” one person said. 有一个人说：“花这个钱真不值得。”
引号中的这句话是承接上文而来的。上文说：“……； others found it expensive。”(……另一些人觉得汉堡包太贵了。)，下文说：“Not good value for money.”。 这是一个不完全句， 意思相当于： It's not worth the high price.
3. The foods that you buy in hamburger restaurants are high in fat, sugar and salt. (= The foods …contain a large amount of fat, sugar and salt.)
你在汉堡包餐馆买的食物所含的脂肪、糖和盐的成分都很高。
这是一个主从复合句，主句是“The foods…are high in fat, sugar and salt.”， 中间插入一个定语从句“that you buy in hamburger restaurants”，修饰先行词foods。 主句中的谓语用了动词词组 “be high in ，同上课学的“be rich in”的意思相近。例如：
Coca Cola is considered to be rich/high in sugar.
人们认为可口可乐的含糖量很高。
The shirts that the shop sells are high in quality.
这家商店出售的衬衫都是高质量的。
4. As a result, many Westerners die at an early age from heart illnesses.
结果许多西方人因心脏疾病而早逝。
die from意思是“死于……(疾病或意外事故等)”。例如：
He died from a serious disease. 他因患重病而死亡。
Scores of people died from floods last summer. 去年夏天，许多人死于水灾。
“因疾病或年老而死亡”还可以用die of。例如：
He died of heart illness. 他因心脏病而死去。
He lived long years and died of old age. 他很长寿，无疾而终(因年老而去世)。
5.在Practice和Discussion中有这样两个疑问句：
Which food do you think is healthy and which is unhealthy?
你认为哪种食物是健康的，哪种是不健康的呢?
Which of the answers do you think is the best one?
你认为在这些答案中哪一个是最佳答案?
这两个特殊疑问句中都有一个插入语“do you think”( 用倒装语序)，其它的部分用正常语序。类似的例句如下：
What performance do you think we should give at the party?
你看我们在晚会上应表演什么节目。
When do you think they will be back? 你认为他们什么时候会回来?
Where do you think we should travel to? 你认为我们该去哪儿旅行。
此外，注意unhealthy的构词法。它是由“前缀un-+形容词”构成。前缀un-有否定的含义，所构成的新词在词义上与原来的形容词词义相反。
