As is widely acknowledged,Chinese food has a long history and is well received internationally. Eating is a highly important feature of China¡¯s culture. With several thousand years of creative efforts, the intelligent and hardworking Chinese people have been able to employ an endless variety of natural ingredients and cooking methods in making Chinese food, which may well account for the universal popularity of Chinese restaurants and Chinese food overseas. A meal in China often consists of main food-typically rice or noodles-and accompanying dishes, such as vegetables, meat, and fish. As for the cooking methods the Chinese people usually use, frying, baking and boiling are among the very common.
As a saying goes,¡±you are what you eat¡±, In my opinion, food is always connected with people, reflecting their different living situations and attitudes. Besides, many Chinese people value the time when the families or friends can get together communicating and sharing good memories.

A super drug that could remove Alzheimer¡¯s (ÀÏÄê³Õ´ôÖ¢)£¬heart disease and diabetes (ÌÇÄò²¡) and help people live to 100 is being developed by scientists. Their research is based on the identification of three genes that help prolong lives and prevent diseases which occur in old age. Medically controlling the proteins made by the ¡° longevity genes¡± will allow millions to live longer, predicts Dr Nir Barzilai.
Those whose DNA strongly features the three genes are 80 percent less likely to develop Alzheimer¡¯s. The genes also fight against the deadly impact of smoking, poor diet, obesity and lack of exercise.
Already, several laboratories are working on a pill to imitate the benefits of the genes and Dr Barzilai thinks it could be tested within three years. The pill could remove some diseases that damage old age. ¡° The advantage of finding a gene that involves longevity is that we can develop a drug that will imitate exactly what this gene is doing,¡± he said.
Of the three longevity genes, two genes increase the production of so-called good cholesterol(µ¨¹Ì´¼), which reduces the risk of heart disease. The third prevents diabetes. They were discovered by Dr Barzilai¡¯s team while studying the DNA of 500 Ashkenazi Jews with an average age of 100. The chances of living that long are one in 10,000 but the group, which shared relatively few common ancestors, was 20 times more likely to hit the entury. Dr Barzilai said: ¡° 30 percent of them were obese or overweight and 30 percent smoked two acks of cigarettes a day for more than 40 years, however they can live to 100.¡±
But Andrew Ketteringham of the Alzheimer¡¯s Society said: ¡°Alzheimer¡¯s disease, a most common disease, is likely to be caused by a combination of genetic disosition(ÒÅ´«ÇãÏò), lifestyles and life events. Many genes are probably involved.
¡¾Ð¡Ìâ1¡¿Some people are able to live to 100 years because of ______.

A£®a magical medicine B£®three special genes C£®good living habits  D£®longevity proteins 
¡¾Ð¡Ìâ2¡¿Why does the discovery of the longevity genes mean a lot?
A£®Because it can bring great benefits to scientific labs.  
B£®Because it can help people change their unhealthy genes 
C£®Because it helps produce a drug that can make people live longer. 
D£®Because it will help scientists build up a new branch of biology. 
¡¾Ð¡Ìâ3¡¿From Paragraph 4 we can infer that ________.
A£®longevity genes can create good cholesterol.  
B£®the volunteers share some common ancestors 
C£®bad habits are likely to have no effect on the volunteers 
D£®longevity genes protect the volunteers against bad habits 
¡¾Ð¡Ìâ4¡¿What is Andrew Ketteringham¡¯s attitude toward the study?
A£®Positive B£®Negative C£®Critical D£®Cautious

The USA is a land of immigrants. Between 1815 and 1914, the world witnessed the greatest peaceful migration in its history: 35 million people, mostly Europeans, left their homelands to start new lives in America. Why did these people risk everything by leaving their homes and families?
First, what forced emigrants to make the decision to leave? One major cause for European farmers to leave was the rise in population which in turn led to land hunger. Another was politics. There was an increased taxation£¨Ë°ÊÕ£©and the growth of armies, and many young men fled eastern Europe to avoid being forced to join the army.
Physical hunger provided another pressing reason. Following the collapse £¨Ë¥ÍË£©of the economy of southern Italy in the 1860s, hundreds of thousands decided to start a new life in America. Religion also encouraged millions to leave the Old World.
In short, people chose to leave their homes for social, economic and religious reasons. As a result, by 1890 among a total population of 63 million, there were more than nine million foreign-born Americans.
But what were the attractions? First of all, there was the promise of land which was so scarce in Europe. Next, factories were calling for workers, and pay conditions were much better than back home. Men were needed to open up the West and build the long railroads, and new towns needed settlers to live in and to develop business. There was the space for religious people to practice their faith in peace.
This immigration meant that by around the 1850s Americans of non-English had started to be more than those of English. As we know, there were losers. To start with, there were those unwilling immigrants, the slaves who had been used as a source of cheap labour. Nor should we forget the equally unlucky American Indians. By 1860 there were 27 million free whites, four million slaves and a mere 488,000 free blacks.
Nowadays, the USA is still seen by millions as the Promised Land. As always, it remains an attractive place to those who think it will offer them a second chance.
¡¾Ð¡Ìâ1¡¿What is not the cause for people to leave their homeland?

A£®The search for religious freedom.B£®The search for adventure.
C£®Unwillingness to join the army.D£®Economics.
¡¾Ð¡Ìâ2¡¿Why was life of the 19th Century European farmers difficult?
A£®There was no land.B£®There was no peace.
C£®The population had gone down.D£®There were too many of them.
¡¾Ð¡Ìâ3¡¿ Which of the following was not an attraction of the USA?
A£®EmploymentB£®A healthy life
C£®freedom of religionD£®Business opportunities
¡¾Ð¡Ìâ4¡¿ What is the topic of this passage?
A£®The USA is still seen by millions as the Promised Land.
B£®The USA is a land of immigrants.
C£®Religion encouraged millions to leave the Old World.
D£®About one-eighth of non-native born Americans live in the USA in 1890.
¡¾Ð¡Ìâ5¡¿ The American Indians __________.
A£®were as fortunate as the slaves
B£®were more unfortunate than the slaves
C£®were the most unfortunate
D£®were as unfortunate as the slaves
