填空题A. The consequence of losing bones B. A better lab in space than on earth C. Two different cases D. Multiple effects form weightlessness E. How to overcome weightlessness F. Factors that are not so sure During weightlessness, the forces within the body undergo dramatic change. Because the spine is no longer compressed, people grow taller. The lungs, heart and other organs within the chest have no weight, and as a result, the rib cage and chest relax and expand. Similarly, the weights of the liver, kidneys, stomach and bowels disappear. One astronaut said after his flight: "You feel your guts floating up. I found myself tightening my belly, sort of pushing things back." 41.______ Meanwhile muscles and bones come to be used in different ways. Our muscles are designed to support us when stand or sit uptight an4 to move body parts. But in space, muscles used for support on the ground are no longer needed for that purpose; moreover, the muscles used for movement around a capsule differ from those used for walking down a hall. Consequently, some muscles rapidly weaken. This doesn't present a problem to space travelers as long as they perform only light work. But preventing the loss of muscle tissue required for heavy work during space walks and preserving muscle for safe return to Earth are the subject of many current experiments. Studies have shown that astronauts lose bone mass from the lower spine, hips and upper leg at a rate of about 1 percent per month for the entire duration of their time in space. Some sites, such as the heel, lose calcium faster than others. Studies of animals taken into space suggest that bone formation also declines. 42.______ Needless to say, these data are indeed cause for concern. During space flight, the loss of bone elevates calcium levels in the body, potentially causing kidney stones and calcium crystals to form in other tissues. Back on the ground, the loss of bone calcium stops within one month, but scientists do not yet know whether the bone recovers completely: too few people have flown in space for long periods. Some bone loss may be permanent, in which case ex-astronauts will always be more prone to broken bones. 43.______ These questions mirror those in our understanding of how the body works here on Earth. For example, elderly women are prone to a loss of bone mass. Scientists understand that many different factors can be involved in this loss, but they do not yet know how the factors act and interact; this makes it difficult to develop an appropriate treatment. So it is with bone loss in space, where the right prescription still awaits discovery. Many other body systems are affected directly and indirectly. One example is the lung. Scientists have studied the lung in space and learned much they could not have learned in laboratories on earth. On the ground the top and bottom parts of the lung have different patterns of air flow and blood flow. But are these patterns the result only of gravity, or also of the nature of the lung itself? Only recently have studies in space provided clear evidence for the latter. Even in the absence of gravity, different parts of the lung have different levels of air flow and blood flow. 45.______ Not everything that affects the body during space flight is related solely to weightlessness. Also affected, for example, are the immune system and the multiple systems responsible for the amount and quality of sleep (light levels and work schedules disrupt the body's normal rhythms). Looking out the spacecraft window just before going to sleep (an action difficult to resist, considering the view) can let enough bright light into the eye to trigger just the wrong brain response, leading to poor sleep. As time goes on, the sleep debt accumulates. For long space voyages, travelers must also face being confined in a tight volume, unable to escape, isolated from the normal life of Earth, living with a small, fixed group of companions who often come from different cultures. These challenges can lead to anxiety, depression, crew tension and other social issues, which affect astronauts just as much as weightlessness-perhaps even more. Because these factors operate at the same time the body is adapting to other environmental changes, it may not be clear which physiological changes result from which factors. Much work remains to be done.

填空题{{B}}Directions:{{/B}} For each numbered blank in the following passage, fill in a suitable word in each blank on the ANSWER SHEET. What is meant {{U}}(51) {{/U}} the word "friend"? The dictionary {{U}}(52) {{/U}} it as: ."one attached to {{U}}(53) {{/U}} by affection or esteem". Americans use the word freely——that is , a friend may or may not be a person {{U}}(54) {{/U}} whom there is a great attachment. A friend might be a casual acquaintance or an intimate companion. Friends may have known each other {{U}}(55) {{/U}} child- hood or they mayhave recently met. It is difficult to formulate a precise {{U}}(56) {{/U}} of this word as it is used in the United States, {{U}}(57) {{/U}} it cover many types of relationships. "My friend and I went to the show last night." "My friends gave me the name of a good doctor." "My friend consoled me when I was depressed." We hear such daily references {{U}}(58) {{/U}} the word "friend" without knowing the quality of the friendship referred to. It is common for Americans to have different "circles of friends" such {{U}}(59) {{/U}} church friends, work friends, or sports friends. A person may choose not to involve members of different circles {{U}}(60) {{/U}} the same activity. (One's friends from the office may never meet one's friends from the sports club. ) {{U}}(61) {{/U}} such as "office mate" and "tennis partner" {{U}}(62) {{/U}} the segregation of friends. The office mate is a friend in the office and the tennis partner is a friend {{U}}(63) {{/U}} the courts. People have different types of friends: one may have many good friends and one best friend. "Best friends" are usually two people of the same sex who have known each other {{U}}(64) {{/U}} a long period of time. People usually have more casual friends than close or best friends. Americans are geographically mobile and learn to {{U}}(65) {{/U}} friendships easily and quickly. Approximately one {{U}}(66) {{/U}} of every five American families moves every year. People relocate {{U}}(67) {{/U}} they begin new jobs, {{U}}(68) {{/U}} distant colleges, get married, have chidren or simply want a change in their lives. Perhaps as a consequence of this, people form and {{U}}(69) {{/U}} friendships quickly. Students attending two or three universities during their undergraduate and graduate years may {{U}}(70) {{/U}} their circles of friends several times.

填空题A．Higher living standard. B．Importance of transport in trade. C．Various , means of transport. D．Birth of transport-related industries and trade. E．Role of information in trade. F．Public transportation. G．Transport facilitating trade. 1 Transport is one of the aids to trade. By moving goods from places where they are plentiful to places where they are scarce, transport adds to their value. The more easily goods can be brought over the distance that separates producer and consumer, the better for trade. When there were no railways, no good roads, no canals, and only small sailing ships, trade was on a small scale. 2 The great advances made in transport during the last two hundred years were accompanied by a big increase in trade. Bigger and faster ships enabled a trade in meat to develop between Britain and New Zealand, for instance. Quicker transport makes possible mass-production and big business, drawing supplies from, and selling goods to, all parts of the globe. Big factories could not exist without transport to carry the large number of workers they need to and from their homes. Big city stores could not have developed unless customers could travel easily from the suburbs and goods delivered to their homes. Big cities could not survive unless food could be brought from a distance. 3 Transport also prevents waste. Much of the fish landed at the ports would be wasted if it could not be taken quickly to inland towns. Transport has given us a much greater variety of foods and goods since we no longer have to live on what is produced locally. Foods, which at one time could be obtained (获得) only during a part of the year, can now be obtained all through the year. Transport has raised the standard of living. 4 By moving fuel, raw materials, and even power, for example, through electric cables, transport has led to the establishment of industries and trade in areas where they would have been impossible before. Districts and countries can concentrate on making things which they can do better and more cheaply than others and can then exchange them with one another. The cheaper and quicker transport becomes, the longer the distance over which goods can profitably be carried. Countries with poor transport have a lower standard of living. 5 Commerce requires not only the moving of goods and people but also the carrying of messages and information. Means of communication, like telephones, cables and radio, send information about prices, supplies, and changing conditions in different parts of the world. In this way, advanced communication systems also help to develop trade.
