We have proof that you become what you eat. When you know the effects of different types of food, you can use your knowledge well and eat what you want to become.

Food has an impact on our physical and mental health. Have you ever heard any of the following advice?

Lettuce (莴苣) or milk can make you sleepy.

To stop feeling sleepy you should eat peanuts or dried fish.

Everyone has their own advice to give, which they have read about or have been told by older relatives. Some of these pieces of advice seem to contradict each other.

Eating chocolate makes you fat and gives you spots.

Chocolate contains the essential minerals: iron and magnesium (镁).

What we need to figure out is what type of chocolate to eat to get the benefits and how much of it to eat. We can do this by reading the list of ingredients (原料) on the chocolate bar package. Exactly how much real chocolate is in there? And how much of that do we need to eat to get the benefits of the minerals it contains?

Future restaurants might be named after the physical or mental state they hope to create. Their menus will list the benefits of each dish and drink. Some restaurants have already started this concept, and list the nutritional (营养的) content of their dishes on the menus.

Let’s take the restaurant “Winners” as an example. Their menu would list dishes specifically designed to help you win sports competitions. Or you could choose the Go-faster salad, which is a large bowl of mixed raw vegetables in a light salad dressing, giving you energy without making you gain weight. And what kind of dishes do you think would be on the menu at the “Clever Café”?

So what’s going to happen to hamburgers and biscuits? Will the concept of eating food, because it’s tasty, go out of fashion? Of course not! Junk food is also changing. If ice-cream is not good for children, can’t we give them fat-free, sugar-free tofu ice-cream? Unhealthy food is going out of fashion, so brands are changing. We are told not to drink cola because of the sugar and caffeine content so cola companies are making sugar-free and caffeine-free drinks. We are told dried fruit is a healthier snack than biscuits so some biscuit companies are making biscuits with added vitamins.

1.By saying “you become what you eat”, the writer means that ________.

A．you will become your own food

B．you will know what food is good by its appearance

C．food has an effect on your health

D．you will know the effects of different types of food

2.What does the underlined word “contradict” mean in the text?

A．Oppose to                             B．Help with

C．Have influence on                       D．Benefit from

3.How can we eat chocolate properly, according to the passage?

A．To eat chocolate containing the essential minerals.

B．To read the list of ingredients on the package.

C．To get advice from others before eating real chocolate.

D．To learn how much chocolate we can consume before eating.

4.Which is true about the future restaurants?

A．The food in “Winners” can ensure you to win sports competitions.

B．They might list the nutritional content of their dishes on the menus.

Ever since they were first put on the market in the early 1990s, gentically mondified (GM, 转基因) foods have been increasingly developed and marketed in many countries in the word,mainly on the basis of their promise to end the worldwide food crisis. But can GM technology solve world hunger problems? Even if it would ,is it the best solutiorr?

Despite what it promiises,GM　 technology actually has not increased the production potential　　 of any corp. In fact

Studies show that the most　 crown GM croo.

GM soybeans, has suffered reduced productivity. For instance, a report than analysed nearly two decades of research on mojor GM food crops shows that GM engineering has failed to significantly increase US crop production.

Something else, however, has been on the rise, While GM seeds are expensive, GM companics tell farmers that they will make good profits by saving money on pesticides（杀虫剂）. On the contrary, US government data show that GM crops in the US have produced an overall increase in pesticide use compared to traditional crops. “ The　 promise was that you could use less chemicals and boost production. But nether is true,” said Bill Christison, President of the US National Farm Coalition.

At the same time, the authors of the book World Hunger: Twelve Myths argue that there actually is more than enough food in the world and that the hunger crisis is not caused by production, but by problems in food distribution and politics. These indeed deserve our efforts and money. Meanwhile, the rise in food prices results from the increased use of crops for fuel rather than food, according to a 2008 World Bank report.

As a matter of fact ,scientists see better ways to feed the world. Another World Bank report concluded that GM crops have little to offer to the challenges of worldwide poverty and hunger, because better ways out are available, among which “green” farming is supposed to be the first choice.

1.The author develops the second paragraph mainly　　　　 .

A. by classification B. by comparison

C. by example D. by process

2.What does the underlined word “boost ” in the third paragraph probably mean?

A. Control. B. Evaluate C. Obtain. D. Increase.

If you’ve never bought organic food, you might be wondering what’s so special about it. Is it really better for you? How does that work? This text will give you a short introduction to the subject.

Organic food is produced without the use of artificial fertilizers or pesticides (insect and bug killers) and many people buy it because they think it’s better for their health. Whether that’s true or not is still debated, but there are lots of other reasons for organic food. Intensive agriculture (集约型农业) gives us cheap and plentiful food, but it’s also one of the biggest sources of environmental pollution. According to a report by the World Resources Institute, half of all the chemical fertilizers ever produced have been used since 1984. Fertilizers — and the much more deadly pesticides and herbicides (weed killers) used with them — finally find their way into rivers and seas. Sometimes they break down harmlessly, but they’re just as likely to build up in creatures that eat them (including humans). Organic food, grown without artificial chemicals, is one way to help reduce the problem.

Many people find it puzzling that organic products are more expensive. After all, you’re doing away with expensive chemicals ... so shouldn’t they be cheaper? Organic farming is typically a more labor-intensive(劳动密集型) way of farming and that’s why it costs more. As a responsible (有责任的) consumer, it’s up to you to decide where to put your money. Are you happy to buy products that may have been grown in a harmful way? Are you willing to pay more to buy organic products that may help to protect the environment?

1.Which of the following does the author agree on?

A. Organic food is better for people’s health.

B. Organic food is better for the environment.

C. Organic food tastes better than traditional food.

D. Organic food can be produced in great amounts.

2.The underlined words “doing away with” in the last paragraph can best be replaced by “______”.

A. making use of B. getting rid of

C. keeping away from D. taking advantage of

3.What’s the author’s attitude towards organic food?

A. Doubtful. B. Uncertain.

C. Worried. D. Supportive.

Although one might not think so as a result of the disadvantages, thousands and thousands of ads have shown advertising is of great importance to the society in which people live, either in the United Kingdom, or in many other parts of the world .Advertising is necessary as a means of communicating with others, of telling them about the goods and services that are offered, and of which most of them would never get to hear at all if it were not for advertising. And advertising does a great deal to a rising standard of living conditions.

In talking about advertisement, one should not think only a commercial on television, or an advertisement in the newspaper or magazines and—in the sense of communication—even the spoken or written words of salesmen. After all, the roots of advertising are to be found in the market place in the ancient times.

For many years it was thought that it was not enough to just produce goods and supply services. It is only more recently that people came to understand the production of goods would be a waste of resources unless those goods can be sold at fair price within a reasonable time period. In the competitive society in which we live, it is very important that we go out and sell what we have to offer, and advertising plays an important part, whether selling at home or in export market. Around 2 percent of the UK national product is spent on advertising. But it must be thought that this advertising tries to sell goods to customers who do not buy them. Of course, advertising does try to catch the eyes of the buyer, but if the product one has bought does not match what the advertisement had described, it is extremely unlikely that the goods will sell well.

1.According to the text, advertising is important to____.

A. every person in the world　　 B. people with a high standard of living

C. some famous companies　　 D. a large number of people in the world

2.What is the earliest advertisement in history?

A. Shop window show and wrapping of the goods.

B. Advertisements on TV

C. face-to-face talks between sellers and buyers

D. Products in many newspapers and magazines

3.The writer tries to tell us that goods will sell well if ____.

A. advertisements are well designed

B. enough money is spent on advertising

C. they are of high quality and well wrapped

D. advertisements mirror the true value
