填空题The person ______ was standing next to me seemed very nervous.

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Directions: In the following article, some sentences have been removed. For Questions 41-45, choose the most suitable one from the list A-G to fit into each of the numbered blanks. There are two extra choices, which do not fit in any of the blanks. Scholars, writers and teachers in the modern academic community have strong feelings about acknowledging the use of another person's ideas. In the English-speaking world, the term plagiarism is used to label the practice of not giving credit for the source of one's ideas. 41．______ 42．______In many universities, the punishment may range from failure in a particular course to expulsion from the university. In the literary world, where writers are protected from plagiarism by international copyright laws, the penalty may range from a small fine to imprisonment and a ruined career. Protection of scholars and writers, through the copyright laws and through the social pressures of the academic and literary communities, is a relatively recent concept. Such social pressures and copyright laws require writers to give scrupulous attention to documentation of their sources. Students, as inexperienced scholars themselves, must avoid various types of plagiarism by being self-critical in their use of other scholars' ideas and by giving appropriate credit for the source of borrowed ideas and words, otherwise dire consequences may occur. 43．______ Plagiarism by accident, or oversight, sometimes is the result of the writer's inability to decide or remember where the idea came from. He may have read it long ago, heard it in a lecture since forgotten, or acquired it second-hand or third-hand from discussions with colleagues. He may also have difficulty in deciding whether the idea is such common knowledge that no reference to the original source is needed. Although this type of plagiarism must be guarded against, it is the least serious and, if lessons learned, can be exempt from being severely punished. Plagiarism through ignorance is simply a way of saying that inexperienced writers often do not know how or when to acknowledge their sources. The techniques for documentation-note- taking, quoting, footnoting, listing bibliography-are easily learned and can prevent the writer from making unknowing mistakes or omissions in his references. 44．______ The most serious kind of academic thievery is plagiarism by intention. The writer, limited by his laziness and dullness, copies the thoughts and language of others and claims them for his own. He not only steals, he tries to deceive the reader into believing the ideas are original. Such words as immoral, dishonest, offensive, and despicable are used to describe the practice of plagiarism by intention. The opposite of plagiarism is acknowledgement. 45．______Students, as developing scholars, writers, teachers, and professional leaders, should recognize and assume their responsibility to document all sources from which language and thoughts are borrowed. Other members of the profession will not only respect the scholarship, they will admire the humility and honesty. [A] The penalties for plagiarism vary from situation to situation. [B] Many scholars suggest rigid self-regulations in academic world in order to protect the purity of academics. [C] "Penalty for plagiarism should be regulated by laws and regulations," said one scholar, "it is no better than theft. " [D] Although there is no copyright in news, or in ideas, only in the expression of them, the writer cannot plead ignorance when his sources for ideas are challenged. [E] Simply stated, plagiarism is "the wrongful appropriation or purloining, and publication as one's own of the ideas, or the expression of ideas of another. " [F] All mature and trustworthy writers make use of the ideas of others but they are careful to acknowledge their indebtedness to their sources. [G] There are at least three classifications of plagiarism as it is revealed in students' inexactness in identifying sources properly. They are plagiarism by accident, by ignorance, and by intention.
