If we want to find out what kind of technology people used in the past, we normally have to rely on archaeologists to find ruined buildings and parts of tools or instruments or machines. Archaeologists then try to reconstruct, sometimes with the help of computer technology, what these ancient buildings and objects must have looked like, and how they might have been made. Sometimes historians are lucky and find an ancient document with a written description of these ancient buildings and objects.

We can understand, then, why Chinese historians were so excited when they found cave paintings which show ancient science. They found these paintings in the world-renowned Mogao Grottoes of Dunhuang City, in Northwest China's Gansu Province. There are 500 man-made caves and they have survived for at least 1,600 years. Almost all of these caves have paintings on their ceilings or walls and they date from the 4th to 14th centuries. Wang Jinyu is an expert on these cave paintings (also called frescoes) and he says: “We discovered frescoes containing scientific and technological content in almost all of the caves which have frescoes.” What is remarkable about these cave paintings according to the Xinhua News Agency is that they provide evidence of "scientific and technological inventions by ancient Chinese in maths, physics, chemistry, astronomy, geography, agronomy, architecture, textiles, traffic and transportation, arms and military equipment and medical sciences".

Among the discoveries experts have made are cave paintings showing ancient techniques of pottery making and wine production and paintings showing ancient weaving machines and then toothbrushes! The paintings also give some evidence of the lifestyle at the time with, for example, pictures of people boiling milk over 1,000 years ago. Experts believe that there is more evidence to be found, but even now the caves are a wonderful natural museum. If the walls and ceilings of the caves were all put together they would form a tapestry 20 kilometers long and 2 meters high!

It won't be possible to travel back in time-that only happens in films-but visiting these caves would be the nearest experience you could get to travelling back in time.

1.Why were Chinese historians excited when they found cave paintings showing ancient science?

A. Because they had rarely seen cave paintings.

B. Because they could make the place a tourist attraction.

C. Because they could learn about ancient science through them.

D. Because they would be given lots of money for the discovery.

Ask most people anywhere in the world what they want out of life and the reply will probably be: “to be happy.” Ed Deiner, an American psychology professor, has spent his whole professional life studying what makes people happy, comparing levels of happiness between cultures and trying to find out exactly why we enjoy ourselves.

Many people would say that this question does not need an answer. But Professor Deiner has one anyway. “If you’re a cheerful, happy person, your marriage is more likely to last, and you’re more likely to make money and be successful at your job. On average, happy people have stronger immune systems, and there is some evidence that they live longer.”

So who are the world’s happiest people? It depends on how the word is defined. There is individual happiness, the sense of joy we get when we do something we like. But there is also the feeling of satisfaction we get when we know that others respect us and approve of how we behave. According to Professor Deiner, the Western world pursues individual happiness while Asia prefers mutual satisfaction.

“In the West, the individualistic culture means that your mood matters much more than it does in the East. People ask themselves if they are doing what is fun or interesting. They become unhappy when they can’t do any of these things. If you ask people from Japan or China if they are happy, they tend to look at what has gone wrong in their lives. If not much has gone wrong, then they are satisfied.”

People from Spain and other Spanish-speaking countries had the happiest culture, Professor Deiner found. “The biggest cultural difference is to do with pride and shame. Hispanic (西班牙语言的) cultures report much more pride and much less shame than others.”

Income also made a big difference to people’s happiness, but only at the lowest levels. Average income earners in the US were much happier than people in poverty. But millionaires were only a little bit happier than people on average incomes. It seems that money makes us happy when we have enough to feel secure.

1.According to the passage, happy people enjoy the following benefits EXCEPT ______.

A. a long marriage

B. better health

C. profession success

D. respect from others

2.In Professor Deiner’s opinion, ______.

A. Asians focus more on others’ respect and approval than westerners

B. Westerners care more about mutual satisfaction than Asians

C. Asians have a culture to enjoy individual happiness

D. Westerners value individual happiness as much as mutual satisfaction

3.What can be inferred from the fifth paragraph?

A. Hispanic cultures lay stress on pride and shame.

B. Spanish people take too much pride in themselves.

C. Attitude towards pride and shame results in Spanish happiness.

D. If you are from Spain, you are the happiest.

4.In the last paragraph, the author seems to tell us ______.

A. poor people enjoy the same happiness as millionaires.

B. the higher income one gets, the happier life he lives

C. enough money can make us feel safe and happy

D. average income earners live the happiest life

5.The passage mainly discusses______.

A. Hispanic cultures

B. reasons for happiness

C. the happiest culture

D. benefits of happiness

We all have ideas about what kinds of foods are good or bad to eat. As a result, people from one culture often think the foods that people from another culture eat are unacceptable. Many people would find it terrible to eat rats, but there are forty-two different cultures whose people regard rats as proper food.

Food likes and dislikes do not always seem related to nutrition. For example, broccoli (花椰菜) is first on a list of the most nutritious common vegetables, but it is twenty-first on a list of vegetables that Americans like most to eat. Tomatoes are sixteenth on the list of most nutritious vegetables, but they are first on the list of vegetables that Americans like most to eat.

But dislikes is not the only reason why some cultures will not eat a certain food. In some cultures, certain foods are taboo. Taboo is a word from the language of the Fiji Islands that is used to describe something that is forbidden. We do not usually think about why certain things are taboo in our culture.

One example is that Americans do not eat dogs, although people from some other cultures regard them as good food. In the United States, dogs are very important to people as pets. They are usually regarded as part of the family, almost like a child in some cases. In addition, dogs have value as protection against criminals (罪犯). Actually, the dog’s place in society as a companion makes the dog taboo as food.

Scientists believe that most food likes and dislikes are a result of the ways of life of different people. People will not eat pets such as dogs. Americans eat a lot of beef because there is plenty of land for raising cattle and their meat can be shipped cheaply for long distances by railroads.

1.The writer uses the example of rat as food to show that ________.

A. some cultures may seem rather strange

B. understanding between different cultures is easy

C. people may eat very different things

D. eating properly is very difficult

2.What is the second paragraph mainly about?

A. People don’t often consider nutrition as important.

B. Some vegetables are more nutritious than others.

C. Broccoli and tomatoes are common vegetables.

D. Americans like broccoli better than tomatoes.

3.Why is eating dogs a taboo in America?

A. It is a taboo from the Fiji Islands.

B. It is against American laws.

C. Dogs are needed by the police.

D. Dogs are close to human life.

4.What can be a suitable title for the passage?

A. Nutritions and Beliefs.

B. Food and Culture.

C. Taboo about Food.

D. Science in Eating.
