单选题A great change in agriculture in the 19th century included two things: the invention of labor-saving machines and the development of scientific agriculture. Labor-saving machines naturally appeared first where more labor was needed. "In Europe," said Thomas Jefferson, "the object is to make good use of their land, labor being abundant(充裕的); here it is to make good use of our labor, land being abundant." It was in America, therefore, that the great advances in the 19th century agricultural machines first came. At the opening of the century, with the exception of a crude plow, farmers could have carried practically all of the existing agricultural tools on their backs; by 1860, most of the machines in use today had been designed in an early form. One of the most important early inventions was the iron plow. As early as 1790 Charles Newbold of New Jersey had been working on the idea of a cast-iron plow and spent his entire fortune in introducing his invention. The farmers, however, would have none of it, declaring that the iron poisoned the soil and made the weeds grow, however, many people devoted their attention to the plow; until in 1869 James Oliver of South Bend, Indiana, turned out the first chilled-steel plow.

单选题People are so used to electric lights, televisions and telephones that it is hard to imagine what life would be like without them. When there is a power failure, people grope about in the dark, cars hesitate in the streets because there are no traffic lights to guide them and food spoils in silent refrigerators. Yet, people began to understand how electricity works only a little more than two centuries ago. Scientists have discovered that the living world may hold many interesting secrets of electricity that could benefit humanity. All living cells send out tiny pulses of electricity. As the heart beats, it sends out electric pulses. They form an electrocardiogram (心电图), which a doctor can study to determine how well the heart is working. The electric currents produced by most living cells are extremely small—often so small that sensitive instruments are needed to record them. But in some animals, certain muscle cells have become so specialized in producing electricity that they do not work as muscle cells any more. The electric eel—a long thin fish with slippery skin—can produce amazingly strong electricity. It can send an electric current as high as eight hundred volts through the water in which it lives. As many as four-fifths of all the cells in the electric eel"s body are capable of producing electricity, and the strength of the shock depends on the length of its body.

Chinese people are now spending more time surfing the net than watching TV, according to results of a survey by the Chinese Academy of Social Sciences (CASS) published Thursday. The survey, of citizens of five Chinese cities, found that 79 percent of interviewees use the internet for information, and 55.1 percent to read news on the internet. About 63 percent of the interviewees use e-mail. The average times spent surfing the net and watching TV were 2.73 hours and 1.29hours, respectively. Only 10.4 percent reported use the internet primarily to send and receive email; 65.9 percent read online news; 62.2 quite often play games on-line. More and more people have taken an interest in the entertainment opportunities online. Up to 56.5 percent of interviewees quite often download music, and 53.5 percent get entertainment messages from the internet. Yet the survey found that television is still the dominant mass medium. Seventy-nine percent of interviewees choose to watch TV to get information, and another 75 percent take newspapers as important as TV. Five major web sites in the Chinese language, namely Sina, Sohu, Netease, Baidu and Yahoo are still ranked top ones by web users, and those that voted for Sina as the best among them were 30.9 percent. Authorized statistics showed that web users in China have already exceeded 100 million, second to that of the United States.

单选题Have you ever wondered what the sky really is? Long ago many thought it circled the earth, carrying the sun, moon, planets, and stars with it. Since then scientists have found that it is really just space. In this space the earth, moon, planets, sun, and other stars are traveling. At times the sky changes its color. When the sun rises or sets, red, orange, yellow, or pink colors are seen. During a clear day the sky is very blue, and on a rainy day it is gray. At night it seems almost black except for the light from the moon and stars. People of old times thought the stars made pictures in the night sky. They saw bears, lions, and many other things. Sailors at sea and shepherds in fields with their sheep knew these. They need only to look. They can go out and view the night sky. No one knows how many stars are there in the sky. They don't know how far the sky reaches out in all directions from the earth. Each new and larger telescope that is built helps scientists see farther out into space. More distant stars and planets are there to be discovered. Most people like to go up into the sky. They travel in balloons and airplanes. People have gone as far as the moon. Someday they will visit distant planets and beyond.
