A "lost tribe" that reached America from Australia may have been the first Native Americans, according to a new theory.
If proved by DNA evidence, the theory will break long established beliefs about the southerly migration of people who entered America across the Bering Strait, found it empty and occupied it.
On this theory rests the belief of Native Americans to have been the first true Americans. They would be classified to the ranks of escapee, beaten to the New World by Aboriginals (土著人) in boats.
To a European, this may seem like an academic argument, but to Americans it is a philosophical question about identity (身份), Silvia Gonzales, of Liverpool University said .
Her claims are based on skeletons found in the California Peninsula of Mexico that have skulls (头骨) quite unlike the broad Mongolian features of Native Americans. These narrow-skulled people have more in common with southern Asians, Aboriginal Australians and people of the South Pacific Region.
The bones, stored at the National Museum of Anthropology (人类学) in Mexico City, have been carbon-dated and one is 12,700 years old, which places it several thousand years before the arrival of people from the North. "We think there were several migration waves into the Americas at different times by different human groups," Dr. Gonzales said． "The timing, route and point of origin of the first colonization of the Americas remains a most contentious topic in human evolution."
But comparisons based on skull shape are not considered conclusive by anthropologists, so a team of Mexican and British scientists, backed by the Natural Environment Research Council, has also attempted to take out DNA from the bones. Dr. Gonzales declined yesterday to say exactly what the results were, as they need to be checked, but indicated that they were consistent（一致） with an Australian origin. It is generally considered that the first Native Americans came from _____.
| A．North Asia | B．Australia | C．South Pacific | D．South Asia |
The skeletons found in the California Peninsula of Mexico have _____.
| A．the broad skull shape |
| B．the narrow skull shape |
| C．different features of Aboriginal Australians |
| D．the same features of Native Americans |
The underlined “contentious” is similar in meaning to “_____”.
| A．likely to cause great interest | B．difficult to solve |
| C．well-known to all | D．likely to cause argument |

| C．Scientists are still not sure about the origin of the Native Americans. |
| D．People began to enter America across the Bering Strait about 12,700 years ago. |
The Albinas married when Mr. Albina was 30, and they spent the early marriage in Argentina. Then they decided to move to Chile, which meant they had to cross the Andes Mountains. They and their 20s sons made the difficult two-week journey on horses. One night there was a terrible snow storm in the mountains, during which Mrs Albina gave birth to triplets (三胞胎), a boy and two girls.
Mrs Albina now has 30 more girls, including the twins who are 15 months old. The oldest Albina children are in their 30s and 40s. They are on their own now, but 18 of the kids still live with their parents in a two-room house. The house has electricity but no toilet or running water. Clearly, the Albinas don’t have enough money and food for the big family. Why, then, do they continue to have children?
The Albinas do not use birth control because it is against their religion. They can let other people take care of their kids, but Mrs Albina doesn’t allow it. “When we were babies,” she said, “our mother left us at an orphanage and never returned. Then a couple adopted my brothers, and I was left behind. I was heartbroken. I promised that when I became a mother I would never give my children away.”
So the Albina family continues to grow. They have so many kids that they run out of names and have to give some children the same name. There are three Susannas, three Miriams, two Estrellas, and two Soledades.
Will the family stop at 53 kids? Mr Albina is 77, and Mrs Albina is 59. “I am getting old,” she said with a smile, “and I would like God to think of me and consider my age. But if God sends more children to me, yes, there will be more.”What is said about the children in the Albinas in the passage?
| A．Some children are raised by others. |
| B．God sent the children to the Albinas. |
| C．The children are all twins or triplets. |
| D．Most of the children are independent now. |
It can be inferred from the passage that______.

| B．the Albinas would like to use birth control |
| C．ten kids in the family share the same name |
| D．the Albina family has lived in three countries |
How old was Mrs Albina when the Albinas got married?
| A．30. | B．25. | C．12. | D．18. |

| B．He doesn’t want to have more. |
| C．He hopes God will give them more. |
| D．He lets nature take its course. |
China has recently been faced with serious issues of product safety. In Panama, it is said that medicine made with a poisonous chemical sickened some people. A Chinese company had identified it as diethylene glycol, a low – cost substitute commonly used in automobile antifreeze.
Some countries have banned Chinese-made toothpaste containing diethylene glycol. China has now told companies to discontinue its use, even though it says the toothpaste is safe. Another industrial chemical, melamine, was found in wheat flour used to make pet food in North America. Thousands of dogs and cats became sick.
The United States has restricted some imports of Chinese seafood because they contained banned substance. And questions have been raised about other products, including children’s toys covered with lead paint.
Chinese officials promised to provide the European Union, the biggest trading partner, with detailed reports on enforcement efforts against unsafe goods.
Meglena Kuneva, commissioner (理事) for consumer protection of the European Union said China should have kept its promise.
China recently closed three companies linked to the Panama and the pet food scare. And it dismissed the former head of its food and drug administration. He was found guilty of corruption (腐败) for approving unsafe drugs. This week, a conference of the State Council approved a proposed special measure on the supervision of food safety. The Xinhua News Agency said it calls for stronger controls over producers, greater responsibilities for government and more serious punishment for illegal activities.
But Chinese officials have accused some foreign media of overstating problems with goods made in China. They say food imports from the United States also fail inspection sometimes.

“How lucky you are to be a doctor…” Anyone who’s a doctor is right out of luck, I thought. Anyone who’s studying medicine should have his head examined.
You may think I want to change my job. Well, at the moment I do. As one of my friends says－even doctors have a few friends－it’s all experience. Experience! I don’t need such experience. I need a warm, comfortable, undisturbed bed of my own. I need it badly. I need all telephones to be thrown down the nearest well, that’s what I need.
All these thoughts fly round my head as I drive my Mini(微型汽车) through the foggy streets of East London at 3:45 a.m. on a December morning. I am a ministering angel in a Mini with a heavy coat and a bag of medicines. As I speed down Lea Bridge in the dark at this horrible morning hour, the heater first blowing hot then cold, my back aching from the car-seat, I do not feel like a ministering angel. I wish I were on the beach in southern France. Call me a bad doctor if you like. Call me what you will. But don’t call me at half past three on a December morning for an ear-ache that you have had for two weeks.
Of course, being a doctor isn’t really all bad. We do have our moments. Once in a while people are ill, once in a while you can help, once in a while you get given a cup of tea and rock-hard cake at two o’clock in the morning－then you worry if you have done everything. But all too often ‘everything’ is a repetitious rule: look, listen, feel, tap, pills, injection, phone, ambulance, away to the next.
And then there is always the cool, warm voice of the girl on the switchboard of the emergency bed service who will get your patient into hospital for you－the pleasant voice that comes to you as you stand in the cold, dark, smelly, dirty telephone box somewhere in a dangerous section of town. Oh, it has its moments, this life does.According to the sentence “Anyone who’s studying medicine should have his head examined,” we know that ___________.

| B．One of his friends says that being a doctor helps one gain all sorts of experience. |

| D．He is not happy with the small and uncomfortable car he is driving. |
The statement “We do have our moments” could best be replaced by “___________”.
| A．we doctors are called at a moment’s notice to see people who need medical treatment |
| B．usually we are glad that we can do something to help the sick |
| C．sometimes we find people are thankful for our help |
| D．there are chances that doctors find their work rewarding and satisfying |

| A．is a bad doctor, unwilling to make a house call during the night-time |
| B．is so dissatisfied with his job that he wishes to find a new one |
| C．is satisfied with his job but he hates to be called out unnecessarily |

| B．the author is annoyed to be called out at such an horrible morning hour for an ear – ache patient |
| C．the author is now heading for the beach in Southern France for his holidays |

The World Health Organization and several other United Nations agencies are calling for a major new effort to fight malaria, tuberculosis and AIDS. These three infectious diseases killed almost 6 million people last year. That is about 10 percent of the total number of deaths around the world last year.
The WHO and UN agencies released a new report at the World Economic Forum in New York City earlier this month. The document says that deaths around the world from malaria and tuberculosis could be cut in half by the year 2010. It also says the number of deaths from AIDS could be reduced 25 percent within that same time period.
The report is called “Calling Up the Response to Infectious Diseases.” It calls for huge new investments in methods to prevent and treat infectious diseases. Officials say money is needed for research and to purchase drugs. Money is also needed to devices to prevent diseases, such as bed nets. Bed nets prevent mosquitoes that carry malaria from biting people while they sleep.
David Heymann, director of the infectious disease program at the World Health Organization, says that providing effective drug treatments is important for improving peoples’ health and economic well – being. Reducing disease can also help improve economic growth in developing countries.
The WHO report also describes successful health programs in developing countries. In Peru, for example, the number of tuberculosis cases was cut in half by increasing the treatment to control the disease. In Vietnam, malaria was reduced 97 percent through the use of bed nets. And in Uganda, cases of the virus that causes AIDS were cut in half among pregnant women and children through the use of anti – AIDS drugs.
This new international health campaign is estimated to cost about 12,000 million dollars a year. So far, officials say the campaign has about 2,000 million dollars. The WHO says the campaign will need stronger relationships among government, private aid agencies, and drug companies to succeed.According to the report is the disease most difficult to fight.
| A．malaria | B．tuberculosis | C．AIDS | D．influenza |
To prevent these diseases, a large amount of money is needed to .
| A．to buy food and pay for the caretakers |
| B．do research work, buy drugs and devices |
| C．take care of the families of the deaths |
| D．set up more hospitals and health institutions |
We can infer from the text that reducing infectious diseases is .
| A．to help the countries develop better |
| B．to promote cooperation between countries |
| C．to help people get more scientific knowledge |
| D．to help people get a cleaner environment |
Most serious infectious diseases spread mainly in .
| A．Africa | B．South America |
| C．Asia | D．developing countries |
To fight the diseases, is necessary.
| A．better environment |
| B．cooperation between different people |
