The Goliath is a true insect because it has six legs and a body that is divided into three parts. Like all beetles, it has two pairs of wings. The front pair are thick and stiff and protect the back pair, which are soft. It is these soft back wings that make the beetle fly forward. They also cause the loud whirring sound the beetle makes when it flies. To steer, the beetle twists and turns its legs the same way you steer a bike by turning its front wheel. African children often use the Goliath beetle as a toy. Although it is over 15 centimeters long, it is quite harmless. 64. The African Goliath beetle is _______.

For some time after that, disease, famine(饥饿) and war kept the population increase down to a rate of 1 percent a year so that more than 15 centuries passed before the population reached 500 million. But in the next 250 years, up to 1850, the population of the world shot to 1 billion and today it has reached 3.5 billion. Scientists say that in the next 35 years the population of the world will double, reaching almost 7 billion by the year 2010. When experts are asked what are the most effective measures that can stop over population, they reply that at least three measures can be considered. (A) Increasing sources and supply of food for under-developed countries. (B) Increasing the industrialization of under- developed countries. (C) Controlling birth. The experts add, however, that none of the above measures can be effective by itself, and that all must be combined into one whole program. They also agree that without controlling of births, any other measures are doomed (注定) to failure. 68. The population _______ because of disease, famine and war. A. didn't increaseB. became less C. increased slowlyD. still increased very fast 69. The population of the world doubled between the year _______. A. 1850 and today B. 100 and the year 1400 C. 100 and the year 1600 D. 1 and the year 100 70. Which of the following is true? A. the richer the country is, the faster the population increase. B. Birth control is the most important way to control the growth of population. C. the population in the developed countries is increasing faster than that in the underdeveloped countries. D. It is impossible to control the increase of the population. 71. The passage was written in ________. A. 1850B. 1936C. 2001D. 1975 E When the six very best students from different cities in Guangdong Province all together chose universities in Hong Kong; when the very best students of Beijing picked up HK University while giving up the nearby Beijing or Qinghua University; when the highest enrollment(录取) rate of Hong Kong Science and Industry University reached 48:1, it’s the high time to ask where the real education heaven for students in China is. Years ago, the answer certainly would be “Beijing or Qinghua University”. But now no one could give the exact reaction without hesitation. The only sure thing is that HK universities have gradually showed an unusual attraction to a great many mainland students. It’s no doubt to call this HK craze (狂热), which is even out of the expectation of those HK universities themselves. How can HK universities shake the steady foundations of Beijing and Qinghua and attract so many mainland students? First, Hong Kong universities offer large-amount scholarship, especially for the top students who can receive the sum scholarship as much as 400,000 HK dollars. Since higher education has become a kind of heavy burden of many families, it’s easy to understand why the reaction to the generous offering of HK universities is great. Second, most HK universities receive professors and students from all over the world and carry out bilingual (双语) education. This kind of excellent language atmosphere is another attraction for mainland students. Furthermore, university students in Hong Kong have a better chance to study abroad as exchange students. Can mainland top universities like Beijing or Qinghua University be calm as before when facing the unexpected competition from HK? Will they take relevant measures to win back the top students who once help them set the worldwide reputation? Time will explain it. The fierce competition brought by HK universities can be a good thing for an entire improvement of education in China. After the awakening and action-taking of mainland universities, they can perform better together with HK universities. (责任编辑：admin) |
