单选题People living on parts of the south coast of England face a serious problem. In 1993, the owners of a large hotel and of several houses discovered, to their horror, that their gardens had disappeared overnight. The sea had eaten into the soft limestone cliffs on which they had been built. While experts were studying the problem, the hotel and several houses disappeared altogether, sliding down the cliff and into the sea. Erosion (侵蚀) of the white cliffs along the south coast of England has always been a problem but it has become more serious in recent years. Dozens of homes have had to be abandoned as the sea has crept farther and farther inland. Experts have studied the areas most affected and have drawn up a map for local people, forecasting the year in which their homes will be swallowed up by the hungry sea. Angry owners have called on the government to erect sea defenses to protect their homes. Government surveyors have pointed out that in most cases, this is impossible. New sea walls would cost hundreds of millions of pounds and would merely make the waves and currents go further along the coast, shifting the problem from one area to another. The danger is likely to continue, they say, until the waves reach an inland area of hard rock which will not be eaten as limestone is. Mean- while, if you want to buy a cheap house with an uncertain future, apply to a house agent in one of the threatened areas on the south coast of England. You can get a house for a knockdown price but it may turn out to be a knockdown home.

A new kind of radar has been developed
for spaceship travelers. A working laboratory model of a new system of radar
that makes use of a beam of light is said to be ten thousand times more accurate
than the best comparable system of radar that uses microwaves.
The model has shown that this radar system, known as laser-dopple radar,
can measure with absolute precision speeds varying from spaceship orbital
injection(进入)velocities(速度)of five miles per second down to virtual stops-speeds
of less than one-thousandth of an inch per second. According to the scientists
who are developing this system, such fine measures of velocity are of prime
importance in space missions. In a rendezvous(对接) between two spaceships, or in
a landing approach by a vehicle onto an orbiting space station, a bump could rip
open a ship's skin, or a nudge could knock the station out of its
orbit. The light-beam radar, which operates at a frequency of
trillions of cycles(百万兆) per second, could easily detect and measure the
movement of a vehicle edging up to a satellite space station. A control system
using so precise a signal as this would allow a huge vehicle to dock at a space
station as lightly as a feather.
单选题Scientists say they now have proof to support the old-fashioned advice that it's best to sleep on a problem. They say sleep strengthens the memory and helps the brain organize the masses of information we receive each day. Lead researcher Bob Stickgold at the Harvard Medical School said, "Sleep helps us draw rules from our experiences. It's like knowing the difference between dogs and cats, even if it's hard to explain. " The US research team studied how well students remembered connections between words and symbols (象征), reports New Scientist. They compared how the students performed if they had had a sleep between seeing the words and having the test, and if they had not slept. They found that people were better able to remember lists of related words after a night's sleep than after the same time spent awake during the day. They also found it easier to remember themes (主题) that the words had in common. But they forgot around one in four more themes if they had been awake. Prof. John Groeger, of Surrey University's Sleep Research Centre, said, "People have been trying for years to find out what the purpose of sleep is, as we know that only certain parts of it have a restorative (有助恢复的) value. " "We form and store huge numbers of experiences in the head every day, and sleep seems to be the way the brain deals with it all./
