Todays policemen in large cities throughout the world rely on modern inventions to help them in their work. In most places motor scooters and police patrol cars have done away with the need to patrol on foot or on horseback. Policemen use telephones, conveniently located throughout their districts, to make immediate contact with headquarters. Radio, television, and computers help to speed the work of the modern force. Even boats and helicopters are part of the equipment of metropolitan police departments. New technical inventions are widely used to fight crime and speed the solution criminal cases. Electronic computers reduce from hours to minutes the time spent in searching for fingerprints. Witnesss descriptions of a criminal are coded and fed into a computer. The machine then sorts through the picture file of known criminals and selects the name and photograph of the most likely suspect. Lie detectors are used to uncover the truth.

The Truth about the Environment

For many environmentalists, the world seems to be getting worse. They have developed a hit-list of our main fears: that natural resources are running out; that the population is ever growing, leaving less and less to eat; that species are becoming extinct in vast numbers, and that the planet's air and water are becoming ever more polluted.

But a quick look at the facts shows a different picture. First, energy and other natural resources have become more abundant, not less so, since the book The Limits to Growth was published in 1972 by a group of scientists. Second, more food is now produced per head of the world's population than at any time in history. Fewer people are starving. Third, although species are indeed becoming extinct, only about 0.7% of them are expected to disappear in the next 50 years, not 25-50%, as has so often been predicted. And finally, most forms of environmental pollution either appear to have been exaggerated, or are temporary-associated with the early phases of industrialisation and therefore best cured not by restricting economic growth, but by accelerating it. One form. of pollution—the release of greenhouse gases that causes global warming—does appear to be a phenomenon that is going to extend well into our future, but its total impact is unlikely to pose a devastating problem.

Yet opinion polls suggest that many people nurture the belief that environmental standards are declining and many factors seem to cause this disjunction between perception and reality.

A．advocate the idea that reading physical paper books is out of fashion

B．introduce a brand new electronic product even more omnivorous than i-phone

C．prove that books will be outweighed by reality shows and porn in the future

D．indicate that books are left out in fictions describing the future world

The top of the world is a wonderland. In winter, the temperature often falls to -30°F and the sun never rises. The ocean is surrounded by frozen ground. There are few people or trees, but to polar bears, the Arctic(北极)is home. Polar bears have thick fur, big paws and other features that make them well prepared for life in their tough environment. In fact, they need the Arctic sea ice for survival. But climate change is causing larger and larger areas of summer sea ice to melt(融化). Experts say that if warming patterns continue, the Arctic could be free of summer sea ice by 2050. That may cause two-thirds of the word s 20,000 polar bears to be gone by then too. Polar bears can t survive for long on land. Seals are their main source of food. The only place where polar bears can hunt seals is on the ice. Although these bears are strong swimmers, they are no match for lightning swift seals in the water. A polar bear has brilliantly clever strategies to overcome this disadvantage. In winter the bear waits motionless beside a seal s breathing hole, which is a narrow tunnel through the ice. Often many hours pass before the seal comes up for air and the bear kills it with a powerful blow of its paw. In summer, the polar bears that live on land eat very little and wait for the sea ice to return. With the sea ice forming later in the year and melting earlier, polar bears do not have enough opportunity to hunt and eat. Less sea ice makes it harder for the bears to catch the seals. The bears must swim longer distances between ice packs(大片浮水), and they cant always make it. The ice is also getting thinner. These conditions can cause polar-bear cubs to become separated from their mothers, who provide them with food. Steven Amstrup is the chief scientist of Polar Bear International. The group aims to save the bears and their home. " The more people who see polar bears and understand their difficult situations, the better the chance well alter our warming path in time to save them," he says.
