The Iceberg Was Only Part ofIt
What doomed the Titanic is well known, at least in outline. On a moonless night of April 15, 1912, the ship hit an iceberg in the North Atlantic ,with 1,500 lives lost.
A century later many people presented new theories to explain the real reason for the disaster. Now two new studies argue that rare states of nature played major roles in the disaster.
The first says Earth’s nearness to the Moon and the Sun — a proximity not matched in more than 1,000 years — resulted in record tides that help explain why the Titanic met with so much ice, including the fatal iceberg.
Recently, a team of researchers found an apparent explanation in the heavens. They discovered that Earth had come unusually close to the Sun and Moon that winter, enhancing their gravitational pulls on the ocean and producing record tides. The rare orbits took place between December 1911 and February 1912 — about two months before the disaster came about. The researchers suggest that the high tides refloated masses of icebergs traditionally stuck along the coastlines of Labrador and Newfoundland and sent them adrift into the North Atlantic shipping lanes.
And a second, put forward by a Titanic historian from Britain, contends that the icy waters created ideal conditions for an unusual type of mirage(海市蜃樓) that hid icebergs from lookouts whose duty was to watch carefully for danger ahead and confused a nearby ship as to the liner’s identity, delaying rescue efforts for hours.
Most people know mirages as natural phenomena caused when hot air near the Earth’s surface bends light rays upward. In a desert, the effect prompts lost travelers to mistake patches of blue sky for pools of water. But another kind of mirage occurs when cold air bends light rays downward. In that case, observers can see objects and settings far over the horizon. The images often undergo quick distortions — not unlike the wavy reflections in a funhouse mirror.
Now, scholars of the Titanic are debating these new theories. Some have different opinions on it. Over all, though, many experts are applauding the fresh perspectives.

Water, which covers about 74 percent of the earth’s surface, is man’s most precious resource. Without it we cannot live. Clean water keeps us alive; polluted water means disease and death. Keeping our water pure is by no means an easy task but it is something that must be done.
Hong Kong once prided herself on being the “Fragrant Harbour”. However, these days, it is not certain if Hong Kong’s harbour could still be called “fragrant”. For, like many other places, Hong Kong has not been spared water pollution. A visit to Tolo and Victoria Harbour, or any of the beaches in Hong Kong is enough to make one aware of the ugly truth that Hong Kong waters are indeed polluted.
The great threat to our water is bacteria pollution. Another great source of water pollution is poisonous chemicals. These substances, which are found in industrial waste and agricultural pesticides, make up unseen dangers that enter biological food chains.
Pollution control is a continuing problem for the government. It is believed that the most effective form of control is legislation（立法）. Most importantly, the present laws on pollution should be given more force. On the other hand, no amount of legislation can effectively control pollution unless those concerned are properly educated about the danger posed by pollution.
While a great majority of Hong Kong citizens and residents seem to be greatly concerned about ways to control water pollution, it is discouraging to note that there are, in our midst, some people who remain apathetic（無動于衷）about the problem. In a recent radio programme conducted on what people in the streets thought about the water pollution problem, one apparently unconcerned person said, “What do I care about water pollution? I don’t drink polluted water. As long as the water I drink is not polluted, I’m not bothered. Water pollution is too big a problem and let’s leave it to the government.”
If all residents in Hong Kong will take such an indifferent attitude, all the government’s attempts to control pollution, let alone the anti-pollution legislation, will prove useless. The best form of pollution control each citizen can employ is to be aware of his surroundings. We hope that someday, the problem of water pollution in Hong Kong will cease to alarm us.
1.By the underlined sentences, the writer wants to show that ______.
A. we should not use polluted water
B. it is our responsibility to keep our water clean and safe
C. clean water is vitally important to the survival of human beings
D. water is abundant but very expensive
2.What can you infer from the second paragraph?
A. Hong Kong indeed deserves the name.
B. Hong Kong never deserves such a name.
C. Hong Kong can’t avoid the damage of pollution.
D. Hong Kong has failed to live up to such reputation.
3.The writer quotes the words in the programme to show us that a block to the solution of the problem is _________.
A. people’s lack of education
B. people’s I-don’t-care attitude
C. people’s wait-and-see attitude
D. people’s over-dependence on the government
4.In the final analysis, the best approach to the problem of water pollution is ________.
A. legislation
B. rapid development of modern science
C. mass education
D.everybody taking care of his own surroundings
B
Two new studies suggest that modern running shoes could increase the risk of injuries to runners.
One study involved sixty-eight healthy young women and men who ran at least twenty-four kilometers a week. The runners were observed on a treadmill machine. Sometimes they wore running shoes. Other times they ran barefoot.
Researchers from the JKM Technologies Company in Virginia, the University of Virginia and the University of Colorado did the study.
They found that running shoes create more stress that could damage knees, hips and ankle joints than running barefoot. They observed that the effect was even greater than the effect reported earlier for walking in high heels.
The study appeared in the official scientific journal of the American Academy of Physical Medicine.
The other study appeared in the journal Nature. It compared runners in the United States and Kenya. The researchers were from Harvard University in Massachusetts, Moi University in Kenya and the University of Glasgow in Scotland.
They divided the runners into three groups. One group had always run shoeless. Another group had always run with shoes. And the third group had changed to shoeless running.
Runners who wear shoes usually come down heel first. That puts great force on the back of the foot. But the study found that barefoot runners generally land on the front or middle of their foot. That way they ease into their landing and avoid striking their heel.
Harvard’s Daniel Lieberman led the study. He says the way most running shoes are designed may explain why those who wear them land on their heels. The heel of the shoe is bigger and heavier than other parts of the shoe, so it would seem more likely to come
down first. Also, the heel generally has thick material under it to soften landings.
60. How many organizations are involved in the two studies?
A. Three. B. Four. C. Five. D. Six.
61. What can we learn from the text?
A. Most running shoes are designed improperly.
B. The design of high heels is better than that of running shoes.
C. No one will run with running shoes in the future.
D. Both of the studies are done in America.
62. Why do running shoes increase the risk of injuries to runners?
A. They could create stress.
B. They’re too big and heavy.
C. They can affect the way the runners land.
D. Their heels can soften landings.
63. How did the researchers do the two studies?
A. By practising. B. By comparing. C. By questioning. D. By reasoning.
