your daily life?
2．What should we eat according to the following passage?? Sometimes people are curious to know what type of food is healthy and what kind of food may hurt our health.The United States Department of Agriculture has prepared a small book to help people learn about which types of food are the healthiest to eat. The book describes six basic food groups: meat, dairy (things made from milk), grains, fruits, and vegetables. The last group is fat, oil, and sweets. As a result of years of research, we know that too much fat is bad for our health. For example, Americans eat a lot of meat and only a small amount of grains, fruits, and vegetables. Because of this, they often get cancer and heart disease. In Japan, on the other hand, people eat large amounts of grains and very little meat. They also have a very low rate (比率)of cancer and heart disease. In fact, the Japanese live longer than people in any other country. Unfortunately, when Japanese people move to the United States, the rate of heart disease and cancer increases as their diet changes. What’s more, as hamburgers and otherhigh-fat foods become common in Japan, the rate of heart disease and cancer is increasing there as well. People are also eating more meat and dairy products in other countries such as Cuba and Hungary. It’s no surprise that the disease rate in these countries is increasing along with the change in diet. Therefore, doctors everywhere advise people to eat more grains, fruits, and vegetables, and eat less meat and dairy products.1．What should we do if we want to keep healthy?

(实际上)没有做”，含有责备或遗憾的语气；其否定形式表示某种行为不该发生却发生了。

driving at top speed, he arrived half an hour early.
A．needn’t B．wouldn’t
C．mustn’t D．couldn’t

一则完整的广告通常包括标题、正文、广告语，有时还包括插图说明等。
1．标题：广告标题不但要传递广告的主要信息，而且要有效吸引读者的注意力。
2．正文：
(1)针对产品的名称、性能、功效、价格等进行符合客观事实的描述，增加说服性和情感性，重点是突出对产品特点和亮点的介绍。 (2)掌握消费者的心理需求，了解市场态势，以重点突出、简明易懂、生动有趣、具有号召力的语言进行传播，以便促成读者的购买行为。
(3)说明销售地址或联系方式。
3．广告语：优秀的广告语往往能够为产品销售鸣锣开道，唤起读者注意，引发读者欲望，促成读者购买。[黄金表达]广告写作的常用句型：
1．祈使句 这是出现最多的句型。
Ask anyone who owns one.
Please do not leave it too late.
2．一般疑问句 通常用在广告的前面。
Have you ever dreamed of ascending the steps of a great temple built to the gods?
Can a tired, overworked voice command attention in class?3．省略句 在英语广告中，省略句比比皆是，甚至整篇广
告都由省略句构成。
Ready for development. For sale. For manufacture. For business. For services.
4．比较级 比较级在广告中用得非常多。
The new Minolta Riva Zoom 105EX is the most compact camera in a very prestigious class.
In short, the stronger your character, the brighter your future. 5．直接引语 在英语广告中多使用直接引语，一是使得广
告显得形式活泼、新颖；二是可以增强说服力。
“Through the NVQ initiative we have discovered talents and competencies we would never otherwise have known about.” Says Ian McDermot of Philips Components in Blackburn.
