Every baby born a decade from now will have its genetic code (基因编码) mapped at birth, the head of the worlds’ leading genome sequencing (基因图谱) company has predicted.
A complete DNA read – out for every newborn will be technically possible and affordable in less than five years, promising a revolution in healthcare, says Jay Flatley, the chief executive of Illumina. Only social and legal problems are likely to delay the age of “genome sequences,” or genetic profiles. By 2019 it will have become routine to map infants’ genes when they are born, Dr Flatly told The Times.
This will open a new approach to medicine, by which conditions such as high blood pressure and heart disease can be predicted and prevented and drugs used more safely and effectively.
A baby’s genome can be discovered at birth by a blood test. By examining a person’s genome, it is possible to identify raised risks of developing diseases such as cancers. Those at high risk can then be screened more regularly, or given drugs or dietary advice to lower their chances of becoming ill.
Personal genomes could also be used to ensure that patients get the medicine that is most likely to work for them and least likely to have side – effects.
The development, however, will raise legal concerns about privacy and access to individuals’ genetic records.
“Bad things can be done with the genome. It could predict something about someone – and you could possibly hand the information to their employer or their insurance company.” said Dr Flatley.
“People have to recognize that this horse is out of the barn, and that your genome probably can’t be protected, because everywhere you go you leave your genome behind. Complete genetic privacy, however, is unlikely to be possible”, he added.
As the benefits become clearer, however, he believes that most people will want their genomes read and interpreted. The risk is nothing compared with the gain.

I came to study in the United States a year ago .Yet I did not know the real American society until I was injured in a car accident because after the accident I had to see a doctor and go to court.
After the accident .my roommate called a doctor for me. I was very grateful and determined to repay him one day. But the next day, he asked me to pay him $200 for what he had done. I was astonished. He had good reason to charge me, he said. And if I wanted to collect money from the person who was responsible for my injury, I’d have to have a good lawyer. And only a good doctor can help me get a good lawyer .Now that he had helped me find a good doctor, it was only fair that I should pay him.
But every day I went to see the doctor, I had to wait about 50 minutes. He would see two or three patients at the same time, and often stop treating one so as to see another. Yet he charged me $115 each time .The final examination report consisted of ten lines, and it cost me $215.
My lawyer was all smiles the first time we met. But after that he avoided seeing me at all. He knew very well the other party was responsible for the accident, yet he hardly did anything. He simply waited to collect his money. He was so irresponsible that I decided to dismiss him. And he made me pay him $770.
Now I had to act as my own lawyer. Due to my inexperience, I told the insurance company the date I was leaving America. Knowing that, they played for time…and I left without getting a cent.
My experiences taught me two things about America: firstly, in a country like America money is everything. It is more important than friendship, honor or professional morality (道德). Secondly, foreigners are still being unfairly treated. So when we talk about America, we should see both its good and bad sides.The author’s roommate offered to help him because________.
| A．he felt sorry for the author |
| B．he thought it was a chance to make some money |
| C．he knew the doctor was a very good one |
| D．he wanted the author to have a good lawyer |
A good doctor is essential for the author to __________.
| A．be properly treated |
| B．talk with the person responsible for the accident |
| C．recover before he leaves America |
| D．eventually get the responsible party to pay for his injury |
The word“charge”in the third paragraph means_________ .
| A．be responsible | B．accuse | C．ask as a price | D．claim |
Both the doctor and the lawyer in this passage are very__________.
| A．friendly | B．selfish | C．professional | D．busy |
What conclusion can you draw from the story?
| A．Going to court is something very common in America. |
| B．One must be very careful while driving a car. |
| C．There are more bad sides in America than good sides. |
| D．Money is more important than other things in the US. |
This year some twenty-three hundred teen-agers (young people aged from 13-19)from all over the world will spend about ten months in U. S. homes. They will attend U. S. schools, meet U. S. teen-agers, and form impressions of the real America. At the same time, about thirteen hundred American teen-agers will go to other countries to learn new languages and gain a new understanding of the rest of the world.
Here is a two-way student exchange in action. Fred, nineteen, spent last year in Germany with George's family. In turn, George's son Mike spent a year in Fred's home in America.
Fred, a lively young man, knew little German when he arrived, but after two months' study, the language began to come to him. School was completely different from what he had expected --much harder. Students rose respectfully when the teacher entered the room. They took fourteen subjects instead of the six that are usual in the United States. There were almost no outside activities.
Family life, too, was different. The father's word was law, and all activities were around the family rather than the individual(个人). Fred found the food too simple at first. Also, he missed having a car.
"Back home, you pick up some friends in a car and go out and have a good time. In Germany, you walk, but you soon learn to like it."
At the same time, in America, Mike, a friendly German boy, was also forming his idea. "I suppose I should criticize American schools", he says. "It is far too easy by our level. But I have to say that I like it very much. In Germany we do nothing but study. Here we take part in many outside activities. I think that maybe your schools are better in training for citizens(公民). There ought to be some middle ground between the two. " This year _____ teen-agers will take part in the exchange programme between America and other countries.
| A．twenty three hundred | B．thirteen hundred |
| C．over three thousand | D．less than two thousand |
The whole exchange programme is mainly to _____ .

Today anyone will accept money in exchange for goods and services. People use money to buy food, furniture, books, bicycles and hundreds of other things we need or want. When they work, they usually get paid in money.
Lots of the money today is made of paper. But people used to use all kinds of things as money. One of the first kinds of money was shells. Shells were not the only things used as money.
In China, cloth and knives were used. In the Philippine Islands, rice was used as money for a long time. Some Africans once used elephant tusks, monkey tails, and salt as money.
The first metal coins were made in China. They were round and had a square hole in the center. Different countries have used different metals and designs for their money. Later, countries began to make coins of gold and silver.
But even gold and silver were inconvenient if you had to buy something expensive. Again the Chinese thought of a way to improve money. They began to use paper money. The first paper money looked more like a note from one person to another than the paper money used today.
Money has had an interesting history, from the days of shell money until today. In the Philippines Islands ______ was once used as money.
| A．rice | B．knife | C．cloth | D．wheat |
What was first used as money? ______.
| A．Elephants tusks | B．Cloth | C．Salt | D．Shells |

| D．round-shaped with a round hole in the middle |
The first paper money ______.
| A．was passed from west Asia to China | B．looked like a note used today |

| B．money must be suited to carry |
| C．people need money to exchange goods with each other |
| D．people prefer metal coins to paper notes |
“Mobile phone killed my man,” screamed one headline last year. Also came claims that an unpublished study had found that mobile phones could cause memory loss. And a British newspaper devoted its front page to a picture supposedly showing how mobile phones could heat the brain.
F
or anyone who uses a mobile phone, these are worrying times. But speak to the scientists whose work is the focus of these scares and you hear a different story.
One of the oddest effects comes from the now famous “memory loss” s
tudy. Alan Preece and his colleagues at the University of Bristol placed a device that imitated the microwave radiation of mobile phones to the left ear of volunteers. The volunteers were good at recalling words and pictures they had been shown on a computer screen. Preece says he still can’t comment on the effects of using a mobile phone for years on end. But he rules out the suggestion that mobile phones have an immediate effect on our cognitive（认识的）abilities. “I’m pretty sure there is no effect on short-term memory,” he says.
Another expert, Tattersall, remarked that his latest findings have removed fears about memory loss. One result, for instance, suggests that nerve cell synapses（神经元突触） exposed to microwaves become more — rather than less — receptive to undergoing changes linked to memory formation.
An even happier outcome would be that microwaves turned out to be good for you. It sounds crazy, but a couple of years ago a
team led by William Adey at the Veterans Affairs Medical Center in California found that mice exposed to microwaves for two hours a day were less likely to develop brain tumours when given a cancer-causing chemical.
“If it doesn’t certainly cause cancer in animals and cells, then it probably isn’t going to cause cancer in humans,” says William. And while there’s still no absolute evidence that mobile phone use does damage your memories or give you cancer, the conclusion is: don’t be afraid. Mobile phone users are worried because ______.
| A．they are not sure whether mobile phones can cause memory loss |
| B．it’s said that mobile phones have a lot of side effects |
| C．one headline reported “Mobile phone killed my man” |
D．a British newspaper s howed mobile phones could heat the brain |
According to this passage, we can know that _____.
| A．the mobile phone is a most wonderful invention |
| B．there’s no need to worry about the radiation from mobile phones |
| C．something must be done to stop people using mobile phones |
| D．mobile phone companies shouldn’t cheat customers |
What would be the best title for this passage? ______.
| A．New Mobile Phones. | B．Special Mobile Phones. |
| C．New Special Investigation: Mobile Phones. | D．New Investigation. |
Australia －a huge island continent that lies to the south of Asia. Australia－more than two hundred years old, a nation that is still growing.
Its big cities lie on the southeast coast, this is where most Australians live. Australians prefer to own their own houses, though some live in apartments. Australians are a suburban（郊区的） people. The suburbs surround the cities for many miles, and so efficient transport is of great importance. As the economy grows, so do its industries- a higher level of production, a wider range of products.
The Australian works hard, but he likes his leisure. The climate makes outdoor activities the most popular.
Canberra, the capital of Australia, is a planned modern city located inland. Australia is governed by a parliamentary democracy(议会民主). The representatives of other countries have their embassies here. Australia wants to strengthen relations with her neighbors.
Australia is a strange land
, a land of vast expanses- fertile valleys, snow fields and deserts- also a land with unique animal, many that can not be found on any other continent in the world today.
Much of the continent is dry, but man has utilized the land, made it productive, with its tools, with its technology. This is the driest continent of all, and water is a precious possession, more precious than all other natural resources. Large dams are built to collect the water, there to irrigate the fields of pastures（牧场） and crops.
But Australia is changing. The land of wool and wheat is now 
a land of large-scale industry and mining. The costs of developing the new mineral discoveries are enormous, but the rewards are great too.
Australia — a young and developing nation. Australia — a nation that wants to communicate with its neighbors. Australia is an island located ______ of Asia and its big cities lie ____ of the coast.
| A．to the south; on the southeast | B．to the north; on the southwest |
| C．to the east; on the northeast | D．to the east; on the southwest |
We can infer from the passage that the Australian likes outdoor activities for the _____ climate.
| A．dull and wet | B．fine and shiny | C．gloomy and rainy | D．wet and cold |
____ is the most precious source in Australia.
| A．Mineral resource | B．Animal | C．Desert | D．Water |
Which of the following statements about Australia is wrong?
| A．Australians are a suburban people |
| B．Australia is governed by a parliamentary democracy. |
| C．Australia prefers to live in the downtown of big cities. |
| D．Wool and wheat used to be the main products of Australia. |
