A high school in Hiroshima City has been the first to do something with DNA in the world. Its students have won praise not only for doing this research but also for presenting their findings to groups of expert scientists. The school is one of the Super Science High Schools allowed by the Ministry of Education, Culture, Sports, Science, and Technology, where students are given an opportunity to study science at an advanced level. Here, students use the same type of hitech experimental laboratories as those found at universities. In these labs, they conduct experiments and research in new fields of study not found in textbooks. As part of this science course, the students, with the help of Hiroshima University, used a machine called sequencer (音序器), and over the course of a year and a half they succeeded in decoding (解译) the DNA. They then presented their results to academic groups. Achieving a world first might sound very wonderful, but the process of decoding the DNA involved very hard work. The students were also responsible for maintaining the equipment, and they had to read difficult research papers and put in extra study beyond their regular schoolwork.

"Researchers need to work hard. The work was tiring, but the students worked toward their ambitious goal of achieving a world first. They have a great sense of achievement, and the number of students who hope to become biologists has increased," said Taruma Akinori, who is in charge of the science course.

In addition to the results being added to the scientific community, the students’ research paper will be translated into English and made available overseas. Moreover, the students have decided to take on a new challenge in DNA decoding.

小题1:Which of the following is the most suitable title for the passage?

A．Decoding the blueprint of life

B．Super Science High School

C．More students hoping to become biologists

D．Hi-tech experimental laboratory小题2:Up to a point, their success is due to ______.

A．hi-tech experimental facilities

B．the great pressure their school put on them

C．the increasing number of biologists

D．little interest in their regular school work小题3: The research paper will be put into English in order to ______.

A．become an English textbook

B．help the students make English friends

C．make the results known by the whole world

D．challenge foreign scientists小题4:The author’s attitude towards those students who have accomplished a world first in DNA decoding is ______.

A．indifferent

B．admiring

C．slighting

D．disappointed

答案

小题1:A

小题2:A

小题3:C

小题4:B

小题1:本文讲述了某中学学生成功解译DNA的事迹,B没有突出主旨,而C、D是文章中的某个细节,只有A"解译生命的蓝图"最符合。

小题2:第二段对该校硬件水平进行了具体描述,由此可知高科技实验设备是帮助学生取得成功的原因之一。B所说的学校给学生施加的巨大压力和D所说的学生们对学校作业没有兴趣,在文中没有体现；由第五段第三句可知C错。

小题3:根据最后一段the students’ research paper will be translated into English and made available overseas可知C正确。

小题4:通读全文可知,作者对成功解译DNA的中学生充满赞赏,对他们付出的努力给予高度评价,因此选B。A(漠然的)、C(轻视的)和D(失望的)均错。

单项选择题

In 1929 John D. Rockefeller decided it was time to sell shares when even a shoe-shine boy offered him a share tip. During the past week The Economist’s economics editor has been advised by a taxi driver, a plumber and a hairdresser that "you can’t go wrong" investing in housing-the more you own the better. Is this a sign that it is time to get out At the very least, as house prices around the world climb to ever loftier heights, and more and more people jump on to the buy-to-let ladder, it is time to expose some of the fallacies regularly trotted out by so many self-appointed housing experts.

One common error is that house prices must continue to rise because of a limited supply of land. For instance, it is argued that "house prices will always rise in London because lots of people want to live here". But this confuses the level of prices with their rate of change. Home prices are bound to be higher in big cities because of land scarcity, but this does not guarantee that urban house prices will keep rising indefinitely-just look at Tokyo’s huge price-drops since 1990. And, though it is true that a fixed supply of homes may push up house prices if the population is rising, this would imply a steady rise in prices, not the 20% annual jumps of recent years.

A second flawed argument is that low interest rates make buying a home cheaper, and so push up demand and prices. Lower interest rates may have allowed some people, who otherwise could not have afforded a mortgage, to buy a home. But many borrowers who think mortgages are cheaper are suffering from money illusion.

Interest rates are not very low in real, inflation-adjusted terms. Initial interest payments may seem low in relation to income, but because inflation is also low it will not erode the real burden of debt as swiftly as it once did. So in later years mortgage payments will be much larger in real terms. To argue that low nominal interest rates make buying a home cheaper is like arguing that a car loan paid off over four years is cheaper than one repaid over two years.

Fallacy number three is a favourite claim of Alan Greenspan, chairman of America’s Federal Reserve. This is that price bubbles are less likely in housing than in the stockmarket because higher transaction costs discourage speculation. In fact, several studies have shown that both in theory and in practice bubbles are more likely in housing than in shares. A study by the IMF finds that a sharp rise in house prices is far more likely to be followed by a bust than is a share-price boom.

The views of Alan Greenspan and the author of the text on price bubbles are （）

A.complementary

B. identical

C. opposite

D. similar
