单选题Japanese Language Today If you want proof that the Japanese language is in decline, just Watch a few parliamentary debates and press conferences on Japanese TV. You won't see politicians talking about what can be done to improve language skills among the country's youth. Rather, you'll see government officials misusing their own language. Recently Prime Minister Keizo Obuchi(小泉纯一郎) called himself a person lacking vocabulay. It seems he's governing a nation of such people. Last May a group of university deans announced the results of a survey showing that a majority of Japanese college students have difficulty expressing themselves fully and clearly in their own language. Throughout Japan, ling juistic skills have been in a downward spiral for at least a decade. Young people who read less and watch more TV than ever before regularly stumble over old proverbs, miss the subtleties of polite expressions and even mistake one written character for another. Japanese is considered one of the world's most difficult languages. Grammar is complicated, and the meanings of words are multifarious (多种多样). There are also different kinds of written characters—ancient Chinese characters known as kanji (日文中的汉字) ,Japanese letters called hiragana and the characters used for foreign words. Many young people struggle with kanji, which are often used to express more ideas. Young people also lack familiarity with Western classics well known to their educated eiders. Many teachers blame video games and television for language problems. Others say that word processors are at fault. To use them, Japanese have to type in Roman letters, then select from a menu of written Japanese and Chinese characters. Since users aren't actually writing the words themselves, experts say it's easy to forget them. But technology is only part of the problem. Some say the real issue is an isolated generation. Young people nowadays don't seem to have conversion with elders who understand the language better. While Japanese educators haven't yet come up with a solution to the language problem, the public does seem ready to take action.

单选题Influenza (流感) Influenza has been with us a long time. According to some Greek writers (51) medical history,the outbreak of 41 2 B. C. was of influenza. The same has been suggested of the sickness (52) swept through the Greek army attacking Syracuse in 395B.C. Influenza is a disease that moves most quickly among people living in (53) conditions,hence,it is likely to attack armies. (54) the nineteenth century there were five widespread outbreaks of influenza. The last of the five (55) in 1889 and marked the beginning of the story of influenza in our time. (56) the recent outbreak,it started in Asia. For more than forty years before that outbreak,influenza had steadily (57) and was believed to be dying out. A new group of outbreaks was (58) by the great outbreak of 1889— 1890 and for the next quarter of a century influenza remained a constant threat. In April 1918 influenza broke out among American troops stationed in France. It quickly spread through all the (59) but caused relatively few deaths. Four months later, however, a second outbreak started which (60) to be a killer. It killed not only the old and already sick but also healthy young adults. It (61) through every country in the world,only a few distant islands in the South Atlantic and the Pacific remaining (62) . It brought the life of whole countries to stop,food (63) stopped and work loss was very great. Before the great outbreak ended,it had killed at (64) 15 million people. Thereafter,there have been several great outbreaks throughout the world. It is thus (65) that influenza is a terrible infection that we have to pay more attention to.

单选题 Listening Device Provides Landslide Early Warning A device that provides early warning of a landslide by monitoring vibrations in soil is being tested by UK researchers. The device could save thousands of lives each year by warning when an area should be evacuated, the scientists say. Such natural disasters are common in countries that experience sudden, heavy rainfall, and can also he triggered by earthquakes and even water erosion. Landslides start when a few particles of soil or rock within a slope start to move, but the early stages can be hard to spot. Following this initial movement, "Slopes can become unstable in a matter of hours or minutes," says Nell Dixon at Loughborough University, UK. He says a warning system that monitors this movement might be enough to evacuate a block of fiats or clear a road, and save lives. The most common way to monitor a slope for signs of an imminent landslide is to watch for changes in its shape. Surveyors can do this by measuring a site directly, or sensors sunk into boreholes or fixed above ground can be used to monitor the shape of a slope. Slopes can, however, change shape without triggering a landslide, so either method is prone to causing false alarms. Now Dixon's team has developed a device that listens for the vibrations caused when particles begin moving within a slope. The device takes the form of a steel pipe dropped into a borehole in a slope. The borehole is filled in with gravel around the pipe to help transmit high-frequency vibrations generated by particles within the slope. These vibrations pass up the tube and are picked up by a sensor on the surface. Software analyses the vibration signal to determine whether a landslide may be imminent. The device is currently being tested in a 6-metre-tall artificial clay embankment in Newcastle, UK. Early results suggest it should provide fewer false positives than existing systems. Once it has been carefully and thoroughly tested, the device could be used to create a complete early-warning system for dangerous slopes. "Locations with a significant risk of landslides could definitely benefit from a machine like this," says Adam Poulter, an expert at the British Red Cross, "as long as it doesn't cost too much." But, Poulter adds that an early-warning system may not be enough on its own. "You need to have the human communication," he says. "Making systems that get warnings to those who need them can be difficult."
