What makes a person a scientist? Does he have ways or tools of learning that are different from those of others? The answer is “no”. It is not the tools a scientist uses but how he uses these tools that makes him a scientist. You will probably agree that knowing how to use a power is important to a carpenter. You will probably agree, too, that knowing how to investigate(调查),how to discover information, is important to everyone. The scientist, however, goes one step further, he must be sure that he has a reasonable answer to his questions and that his answer can be confirmed by other persons. He also works to fit the answers he gets to many questions into a large set of ideas about how the world works.

The scientist’s knowledge must be exact. There is no room for half right or right just half the time. He must be as nearly right as the conditions permit. What works under one set of conditions at one time must work under the same conditions at other times. If the conditions are different, any changes the scientist observes in a demonstration must be explained by the changes in the conditions. This is one reason that investigations are important in science. Albert Einstein, who developed the theory of relativity, arrived at this theory through mathematics. The accuracy of his mathematics was later tested through investigations, Einstein’s ideas were shown to be correct. A scientist uses many tools for measurements. Then the measurements are used to make mathematical calculations that may test his investigations.

The massive magnitude（震级） 8.8 earthquake that struck the west coast of Chile moved the entire city of Concepcion at least 10 feet to the west, and moved other parts of South America as far apart as the Falkland Islands and Fortaleza, Brazil.

These measurements, produced from data gathered by researchers from four universities and several agencies, paint a much clearer picture of the power behind this earthquake, believed to be the fifth-most-powerful since instruments have been available to measure earthquake.

Buenos Aires, the capital of Argentina moved about 1 inch to the west. And Chile's capital, Santiago, moved about 11 inches to the west-southwest. The cities of Valparaiso and Mendoza, Argentina, northeast of Concepcion, also moved.

The quake's epicenter (震中) was in a region of South America that's part of the so-called “ring of fire,” an area of major seismic（地震的） stresses which encircles（环绕，包围） the Pacific Ocean. All along this line, the plates on which the continents move press against each other.

Mike Bevis, professor of earth sciences at Ohio State, has led a project since 1993 that has been measuring crustal（地壳的）movement in the Central and Southern Andes. The effort is called the Central and Southern Andes GPS Project, or CAP.

Ben Brooks, an associate researcher with the School of Ocean and Earth Science and Technology at the University of Hawaii, said that the event, offers a unique opportunity to better understand the seismic processes that control earthquakes.

“We now have modern, precise instruments to evaluate this event, and because the site borders a continent, we will be able to get evidences of the changes it caused.” said Brooks.

Australia – The vote for euthanasia (安乐死) was finally taken at 3:45 this morning. After six months’ argument and final 16 hours’ hot debates. Australia’s Northern Territory became the first legal authority in the world to allow doctors to take the lives of incurably ill patients who wish to die. The bill was passed by the vote of 15 to 10. Almost immediately world flashed on the Internet and was picked up, half a world away, by John Hofsess, the director of the Right to Die Society of Canada. He sent it on through the group’s on – line service, Death NET. Hofsess says, “We posted it all day long, because this isn’t just something that happened in Australia. It’s world history.”

The full import may take a while to understand. The NT Rights of the Terminally Ill law has left physicians and citizens trying to deal with its moral and practical implications. Some have breathed sighs of relief; but others, including churches, right to life groups and the Australian Medical Association, bitterly attacked the bill and the haste of its passage. But the tide is unlikely to turn back. In Australia--where an aging population, life-extending technology and changing community attitudes have all played their part—other states are going to consider making a similar law to for euthanasia. In the U. S. and Canada, where the right to die movement is gathering strength, observers are waiting for the dominoes (多米诺骨牌) to start failing.

Under the new Northern Territory law, an adult patient can request death--probably by a deadly injection or pill--to put an end to suffering. The patient must be diagnosed as incurably ill by two doctors. After a "cooling off" period of seven days, the patient can sign a certificate of request. After 48 hours the wish for death can be met. For Lloyd Nickson, a 54-year-old Darwin resident suffering from lung cancer, the NT Rights of Terminally Ill law means he can get on with living without the haunting fear of his suffering: a terrifying deat from his breathing condition. "I' m not afraid of dying from a spiritual point of view, but what I was afraid of washow I'd go, because I've watched people die in the hospital fighting for oxygen and clawing at their masks," he says.

According to the text, which of the following statements is TURE?

    A．Australia now us the only country in the world to pass the law of euthanasia.

    B．All people in Australia don’t have the same positive attitude to euthanasia.

    C．Many patients will ask their doctors for euthanasia because they are afraid of death.

    D．According to the law, if a patient requests death, his or her wish will be met after 48 hours.

The underlined sentence in Para 2, “observes are waiting for the dominoes to start falling.” means that observes are waiting to see         .

    A．the result of the game of dominoes.

    B．that people’s attitude to euthanasia will be changed.

    C．that the bill about euthanasia in Australia will come to an end.

    D．the similar bills will be passed in other countries.

Australia was the first country to pass the bill of euthanasia, but not USA or Canada. Which one is NOT the reason?

    A．In Australia, the technology of extending life is advanced.

    B．In Australia, it is easy to deal with the moral and practical meaning.

    C．In Australia, old people take up great part in the population of the whole country.

    D．Australians gradually realize suffering from a terrible disease is worse than immediate death.

It can be inferred from the text that          .

    A．when Lloyd Nickson dies, he will face his death with calm characteristic of euthanasia.

    B．physicians and citizens in Australia share the same view on euthanasia.

    C．other countries are going to consider making a similar law to deal with euthanasia.

    D．under the bill, patients requesting death are sure to be injected by deadly medicine.

What’s the author’s attitude to euthanasia?

    A．Negative B．Critical C．Positive D．Doubtful
