The recent, apparently successful, prediction by mathematical models of an appearance of El Nino—the warm ocean How that periodically develops along the Pacific coast of South America has excited researchers．Jacob Bjerknes pointed out years ago how winds might create either abnormally warm or abnormally cold water in the eastern equatorial （赤道附近的） Pacific．Nevertheless, before the creation of the models, no one could explain why conditions should regularly change between appearances of the warm El Nino and the so-called anti-El Nino．The answer, at least if the current model that links the behavior of the ocean to that of the atmosphere is correct, is to be found in the ocean．
It has long been known that during an El Nino, two conditions exist: unusually warm water extends along the eastern Pacific and winds blow from the west into the warmer air rising over the warm water in the east．The contribution of the model is to show that the winds of an El Nino, which raise sea level in the east, send a signal to the west lowering sea level at the same time．According to the model, that signal is created as a negative （负的） Rossby wave, a wave of lower sea level, that moves westward parallel to the equator at 25 to 85 kilometers per day．Taking months to move across the Pacific, Rossby waves march to the western boundary of the Pacific basin, which is modeled as a smootli wall but in reality consists of quite irregular island chains．
When the waves meet the western boundary, they are reflected, and the model predicts that Rossby waves will be broken into many coastal Kelvin waves carrying the same negative sea-level signal．These eventually shoot toward the equator, and then head eastward along the equator drove by the earth at a．speed of about．250 kilometers per day．When enough Kelvin waves of adequate amplitude （振幅） arrive from the western Pacific, their negative sea-level signal overcomes the feedback mechanism, raising the sea level, and they begin to drive the system into the opposite cold mode．This produces a gradual change in winds, one that will eventually send positive sea-level Rossby waves westward, waves that will eventually return as cold cycle—ending positive Kelvin waves beginning another warming cycle．

The advantages and disadvantages of a large population have long been a subject of
discussion among economists. It has been argued that the supply of good land is limited. To feed a large population, poor land must be cultivated and good land made full use of. Thus, each person produces less and this means a lower average income than could be obtained with a smaller population. Other economists have argued that a large population gives more opportunities for specialization such as ports, roads, and railways, which are not likely to be built unless there is a big demand to justify them.
One of the difficulties in carrying out a world-wide birth control program lies in the fact that official attitudes to population growth vary from country to country depending on the level of industrial development and the availability of food and raw materials. In a developing country where a vast expanding population is pressing hard upon the limits of food, space and natural resources, it will be the first concern of the government to place a limit on the birthrate, whatever the consequences may be. In a highly industrialized society the problem may be more complex. A decreasing birthrate may lead to unemployment because it results in a declining market for products. When the pressure of the population on housing declines, prices also decline and the building industry is weakened. Faced with considerations such as these, the government of a developed country may well prefer to see a slowly increasing population, rather than one which is stable or in decline.
54．According to the first paragraph, a smaller population may mean______ if land is limited.
A．lower productivity, and a lower average income
B．lower productivity, but a higher average income
C．higher productivity, and a higher average income
D．higher productivity, but a lower average income
55．In a developed country, people will perhaps go out of work if the birthrate_______.
A．goes up B．goes down  C．remains stable  D．is limited
56．It is not easy to carry out a worldwide birth-control program because______.
A．there are too many underdeveloped countries in the world
B．developing countries are short of food and raw materials
C．even developed countries may have some complex problems of population
D．different governments show quite opposite views to the population

The most detailed breakdown(分析) of ethnic and gender performance in national curriculum tests for 7, 11 and 14－year－olds shows that Chinese pupils do best in every subject at every age. Chinese and Indian pupils outperformed white British children in English tests for 11－year－olds. In all, 83% of Chinese students reached the required standard compared with 78% of Indian pupils and 75% of white UK pupils and only 65% of Bangladeshi children reaching level four, the standard that an 11－year－old should achieve.
While the overall results show the performance of every ethnic group at GCSE(中等教育普通证书) is improving, they do highlight a worrying trend for white British pupils. David Miliband, the minister for School Standards, said the results showed that while standards in secondary schools were rising, there was “a shocking gender gap between boys and girls”. He added: “58.2% of girls achieved five A to C grade passes at GCSE in 2003 compared with just 49.9% of boys, and white working－class boys are one of the lowest performing groups at 14.” According to researchers,” In the weeks leading up to GCSE unsupervised study leave at home in many areas has become the norm(惯例). They are left to their own devices.” Mr. Miliband is supporting a plan to persuade schools to drop study leave before GCSEs and replace it with structured revision in school.

The ’80s’ “important role” in the family has also meant a greater concentration and focus on the individual. And, it has made the word “me” one of the most frequently used words. Everything seems to be about “me”. This generation has a greater awareness of itself.
Some people do not seem to agree that all this is self-centred. When Cai Fuchao, Beijing’s publicity head, was asked to comment on the lack of responsibility of university students during the SARS period, his reply was: “Modern university students are ambitious, knowledgeable and have a very strong sense of responsibility to the society.”
As news analyst from sina.com, Pan Fengliang, echoed（随声附和）that, saying that blindly blaming them(for running away during the SARS outbreak) was prejudiced and unfair and not backed with evidence.
No doubt, the development of information technology has contributed its bit to broadening, or bending, the minds of the 80s generation.
Some people even call Gen’80 “the E-generation”. They get in touch with each other via email, QQ, ICQ and MSN.
While the people of the ’60s and ’70s swarmed（涌往）to Shanghai to catch Luo Dayou, Gen’80s were on the BBS saying that it was “really dumb”.
“The internet is so much more to those of the ’80s than you can imagine,” said Wu Junyong, an IT engineer who was born in 1978.
In Wu’s opinion, it’s the Internet that separates the 70s from the 80s, “Many of the’70s don’t see why those from the ’80s can spend everyday in front of a computer.”
A new weekly Magazine/163.com survey last year found that 40 percent of the 7,000 people surveyed, born in the ’80s, thought the computer was the most important article in life; more than 70 percent of their parents preferred the home.
67. Which of the following statements is true according to the passage?

C.All the ’80s can spend every day in front of a computer.
D.Not all people think that the “born in the 1980s” are selfish and irresponsible.
68. What can we infer from the passage?
A. All the ’80s have a strong sense of responsibility to the society.
B.Computers play a more important part in the life of the ’80s, who perhaps can’t live without them.
C.The ’80s generation are ambitious, knowledgeable and responsible.
D.People can’t imagine why the ’80s like internet so much.
