Chocolate is good for your heart, skin and brain. Usually, people think that chocolate is bad for their health. They describe chocolate as “something to die for” or say “death by chocolate”. Now they should bite their tongues! Evidence is showing that some kinds of chocolate are actually good for you in the following ways:
A happier heart
Scientists at Harvard University recently examined 136 studies on cocoa— the main ingredient in chocolate— and found that it does seem to strengthen the heart. Studies have shown heart benefits from increased blood flow. These benefits are the result of cocoa’s chemicals, which seem to prevent both cell damage and inflammation(炎症)。
Better blood pressure
If yours is high, chocolate may help. Jeffrey Blumberg from Tufts University recently found that people with high blood pressure who ate 3.5ounces of dark chocolate per day for two weeks saw their blood pressure drop quickly.
Muscle magic
Chocolate milk may help you recover after a hard workout(锻炼). In a small study at Indiana University, people who drank chocolate milk between workouts did better on a tiredness test than those who had some sports drinks.
Better for your skin
German researchers gave 24 women a half-cup of special cocoa every day. After three months, the women’s skin was moister(润滑的) and smoother. The research shows that chocolate helps protect and increase blood flow to the skin, improving its appearance.
Brain gains.
It sounds almost too good to be true, but research suggests that chocolate may improve your memory, attention span, reaction time, and problem-solving skills by increasing blood flow to the brain.

The consumer(消费者) plays a very important role in the global efforts to reduce C02 emissions(排放). Households use one third of the final energy and produce around two thirds of city waste in the European Union. Besides,housing, food,and private transport make up almost 80% of environmental pressures. Therefore there’s no doubt that consumers can make a real difference in fighting climate change.
To direct consumers towards more environmentally-friendly decisions,we need clear and simple instructions to guide consumption behavior. Actually, two thirds of consumers find it hard to figure out which products are better for the environment, for 58% Europeans think that many businesses just pretend to be green so as to charge higher prices. Thus industry should work harder to give consumers more information about the carbon footprint of their product. For example, inform customers of products made from materials that are recycled,renewable, and/or less carbon-intensive.
People prefer high-quality products that will last long and won’t go out of style, though they might sometimes cost more, especially in time of crisis. Firms that make durable(持久耐用的) or recyclable products cause people to behave more responsibly, which may help put an end to our “throw-way” culture.
However, it is not enough to remind people of green products. It’s more important to direct people to follow a practical lifestyle model. Regulations(规则) alone cannot achieve this purpose. We call for good business communities to create a loyal group of “sustainable(可持续的) consumers”.
According to the passage, the key to going greener globally is

A.to provide enough information about sustainable products
B.to get the government involved in protecting the environment
C.to encourage consumers to make their efforts to live a green way
D.to direct companies to provide environmentally-friendly products

The second paragraph tried to tell us that

A.people are buying sustainable products to have a lighter carbon footprint
B.most European consumers lack confidence in making responsible choices
C.companies have done enough to allow consumers to make greener choices
D.companies can make more money by making less carbon-intensive products

It’s advised that companies had betterespecially in the time of crisis.

A.throw away old materials
B.reduce the cost of production
C.make more durable products
D.replace their products frequently

The last paragraph puts emphasis on ___________.

A.the quality of products.
B.the honesty of companies.
C.the government regulations.
D.the importance of lifestyle.

United States and Canada are multicultural countries with many national, religious and cultural differences, where people attach great importance to individualism—the uniqueness among people. Teachers value the qualities that make each student special and different. You can see such values through their educational systems. For example, students needn’t memorize lots of information. Instead, they work independently and find answers on their own. There are discussions for children to show their own ideas and opinions.
By contrast, people have the same language, history, and culture in most Asian societies. As a result, Asia’s educational system reflects society’s belief in group goals and purposes rather than individualism. Children in China, Japan, and Korea learn to work together and help one another in assignments. And the teaching methods are often very formal and serious. In class, teachers give lectures while students listen and take notes. Discussion is replaced by reciting rules of information that have been memorized.
These two systems both have advantages and disadvantages. One advantage in Japan is that there is much more math and science than American students learn by the end of high school. In addition, students study more hours each day and more days each year than North Americans do. The difficult system also prepares students for a society that place emphasis on discipline(纪律) and self-control. However, while memorization is an important learning method in Japanese schools, yet many students admit forgetting much of the information that they have memorized after exams.
On the other hand, the educational system in North American has an advantage that students learn to think for themselves, which prepares them for a society that values creativity. The disadvantage is that when they graduate from high school, they haven’t recited as many basic rules and facts as students in other countries have.
People in multicultural countries such as the US or Canada lay more stress on __________.

A.team work B.self-control C.discipline D.individualism

What is the advantage of the educational system in North America?

A.There is not much discussion.
B.Learning to think for themselves
C.Learning much less math and science
D.They haven’t memorized basic rules and facts.

We can make mistakes at any age. Some mistakes we make are about money. But most mistakes are about people. “Did Jerry really care when I broke up(分开) with Helen?” “When I got that great job, did Jim, as a friend, really feel good about it?” “And was Paul friendly just because I had a car?” When we look back, these thoughts can make us feel bad. But when we look back, it is too late.
Why do we go wrong with our friends, or our enemies? Sometimes what people say hides their real meanings. And if we do not really listen, we miss the feeling behind the words. When someone tells you, “You’re a lucky dog!” Is he really on your side? If he says, “You’re a lucky guy!” That is being friendly. But “a lucky dog”? There is a bit of envy (嫉妒) in those words. What he may be saying is that he does not think you deserve (应得) your luck.
“Just think of all the things you have to be thankful for” is another phrase(短语) that says one thing and means another. It could mean that the speaker is trying to get you to see your problem. But this phrase contains the thought that your problem is not at all important.
How can you tell the real meaning behind someone’s words? One way is to take a good look at the person talking. Do his words fit the way he looks? Is what he says shown by the tone of voice? The look in his eyes? Stop and think. The minute you spend thinking about the real meaning of what people say to you may save your another mistake.

In the United States, when one becomes rich, he wants people to know it. And even if he does not become very rich, he wants people to think that he is. That is what “keeping up with the Joneses” is about. It is the story of someone who tried to look as rich as his neighbors.
The expression was first used in 1913 by a young American called Arthur Momand. He told this story about himself. He began earning $ 125 a week at the age of 23. That was a lot of money in those days. He got married and moved with his wife to a very wealthy neighborhood outside New York City. When he saw that rich people rode horses, Momand went horseback riding every day. When he saw that rich people had servants, Momand and his wife also hired a servant and gave big parties for their new neighbors.
It was like a race, but one could never finish his race because one was always trying to keep up. The race ended for Momand and his wife when they could no longer pay for their new way of life. They moved back to an apartment in New York City.
Momand looked around him and noticed that many people do things just to keep up with rich lifestyle of their neighbors. He saw the funny side of it and started to write a series of short stories. He called it “Keeping up with the Joneses” because “Jones” is a very common name in the United States. “Keeping up with the Joneses” came to mean keeping up with rich lifestyle of the people around you. Momand’s series appeared in different newspapers across the country for over 28 years.
People never seem to get tired of keeping up with the Joneses. And there are “Joneses” in every city of the world. But one must get tired of trying to keep up with the Joneses because no matter what one does, Mr. Jones always seems to be ahead.
Some people want to keep up with the Joneses because they ________.

A.want to be as rich as their neighbors
B.want others to know or to think that they are rich
C.don’t want others to know they are rich
D.want to be happy

It can be inferred (推断) from the story that rich people like to ________.

A.live outside New York City B.live in New York city
C.live in apartments D.have many neighbors

Arthur Momand used the name “Jones” in his series of short stories because “Jones” is _____.

A.an important name B.a popular name in the United States
C.his neighbor’s name D.not a good name

According to the writer, it is ________ to keep up with the Joneses.

A.correct B.interesting C.impossible D.good
