How long you live has a lot to do with your environment and lifestyle, but exceptional(特别的)long life may have even more to do with your genes. For the first time, researchers have discovered a genetic recipe(基因谱)that accurately predicts who may live to 100 and beyond.

Analysis shows that 90% of the participants who lived to 100 had at least one of the signature genetic clusters(标志基因组). Dr. Thomas Perls at the Boston University School of Medicine said, “We realize this is a complex genetic puzzle. There is a long way for us to go to understand how the integration(融合)of these genes—not just with themselves but with environmental factors—is playing a role in this long life puzzle.”

Perls has studied many factors that contribute to long life, and he is the first to acknowledge that living longer isn’t likely to be simply a matter of genes. His previous work has shown, for example, that among most elderly people who live into their 70s and 80s, about 70% can owe their long life to environmental factors such as not smoking; eating a healthy, low-fat, low-calorie diet; and remaining socially engaged and mentally active throughout life.

It seems clear that those who live extremely long are benefiting from a special DNA. In fact, Perls believes that the older a person gets, the more likely it is that his or her genes are contributing to those extended years.

A. Most long-living people have special long-life-related genes.

B. Ninety percent of the participants lived to 100 years of age. 

C. All the long-living people have only one signature genetic cluster.

D. Scientists know how the integration of the genes helps people live long.

2. Perls may most likely agree that         .

A. most people living extremely long benefit from not smoking 

B. living longer just depends on certain genetic recipes

C. environmental factors play an important role in long-living

D. being mentally active has nothing to do with living an old age

3. Which of the following is FALSE according to the text?

A. Remaining socially engaged helps a person to live long.

B. A genetic recipe can accurately predict who may live to 100 and beyond.

C. Perls is the first to think living longer is just a matter of genes.

D. The older he gets, the more likely the genes contribute to his extended years.

4.Which of the following would be the best title for the text?

A. Genes May Predict Who Lives to 100         B. Environment And Genes

C. Genes, the Secret of Long Living           D. Lifestyle And Genes

The Mandarin Chinese word for “cha” is pronounced “t'e” in certain Chinese dialects(方言). Also the Malay word for the leaf is“the”. This word “the” was used to describe both the drink and the leaf. The Japanese character for tea is written exactly the same as the Chinese, though pronounced with a slight difference; so these may be the origins of our word tea in the western world.

Tea may have been discovered in 2737 BC by Shen Nong, a Chinese Emperor of the San Huang Period（3,000 - 2,700 BC）. He was a scholar, the father of agriculture and the inventor of Chinese herbal medicine. One summer day, while visiting a distant place, he and the court stopped to rest and his servants began to boil water for the court to drink. Dried leaves from the nearby bush fell into the boiling water, and made it a brown liquid. The Emperor was interested in the new liquid, drank some, and found it very refreshing. The tree was a wild tea tree, and so, tea was created.

The first samples(样品) of tea reached England between 1652 and 1654. Tea was referred to as the China drink, tcha, chaw, tay, tee, and tea and was at first regarded more as a medicine than a fashionable drink. The original English pronunciation of the word tea was “tay” and can be traced back to around 1655 when the Dutch introduced both word and beverage（饮料）to England. The pronunciation “tee” also originated in the 1600's but only gained predominance（主导地位）after the late 18th century.

By 1650 the Dutch were actively involved in trade throughout the Western world. During that year Peter Stuyvesant brought the first tea to America to the colonists（殖民地定居者）in the Dutch settlement of New Amsterdam （later re-named New York）.

1.The following information is true EXCEPT ________.

A. The Japanese write the character for tea the same way as we Chinese.

B. It was a Chinese Emperor who first found tea very refreshing.

C. The word “the” was used to describe only the leaf.

D. Tea was discovered quite by chance in history.

2.Paragraph 2 mainly tells us ________.

A. that Shen Nong, was a famous inventor of Chinese herbal medicine

B. why the Emperor was brave and dared to run risks

C. whether Shen Nong liked drinking boiled water outside the court

D. the way in which tea was created outdoors

① Tea was at first regarded just as a fashionable drink in England.

② Tea had different names during the early days it reached England.

③ The pronunciation “tee”originated in 1600.

④ Peter Stuyvesant introduced both word “tay” and beverage（饮料）to England.

⑤ The pronunciation“tee”became popular after the late 18th century.

A. ①②     B. ②③     C. ④⑤     D. ①④   

4.From Paragraph 3 we know ________.

A. that the leaf tea should be put in hot water for drinking 

B. that tea was called the China drink, tcha, chaw, tay, tee, t'e and tea in England

C. what the early situation of tea was like in the Western world

 It often seems that people have a hard time in speaking a seemingly familiar name. Did you ever have someone's name on the tip of your tongue and yet you were not able to recall it? When this happened，what did you do? Next time this happens again，what should you do?

You should not try to recall it. Instead, just do something else for a couple of minutes and then the name may come into your head. Why? The name is just there, since you have met this person and learned his name. It, waiting there, only has to be dug out. The initial(最初的) effort to recall prepares the mind for operation, but it is the subconscious (下意识的) activities that go to work to dig up a dim（模糊的）memory. Forcing yourself to recall almost never helps because it doesn't loosen your memory; it only tightens it.

That’s why students find the preparatory method greatly helpful in examinations. They read over the questions before trying to answer any of them. Then they answer first the ones of which they are most confident. At the same time, deeper mental activities in the subconscious mind are taking place; work is being done on the more difficult questions. By the time the easier questions are answered, answers to the more difficult ones will usually begin to come into consciousness. It is often just a question of waiting for recall to come to the memory.

You see, forcing ourselves to think hard to recall something usually doesn’t help. Chances are that the harder we think, the more difficulty we face in thinking of what we want to. Offering our mind time to work is what we are expected to do.
