单选题. Around 1975 a number of books were written about strange occurrences in the Bermuda Triangle, a part of the Atlantic Ocean off the southeast coast off the U.S. They told the stories of planes and ships that disappeared for no understandable reason and were never found again. They told about ships which were found undamaged but with no one on them. According to the books, more than 1,000 people disappeared in the Triangle from 1945 to 1975. According to some writers, there were no natural explanations for many of the disappearances, so they suggested other explanations. For example, according to the writer, some strange and terrible power exists in the Triangle. According to another writer, people from space are living at the bottom of the Atlantic, and sometimes they need human sailors and airmen for their research. These ideas were not scientific, but they were good advertisements. The books about the Bermuda Triangle were immediate successes. However, the books give little evidence to support their unusual ideas. In addition, they ignore at least three important facts that suggest natural reasons for many of the occurrences. First, messages from some of the ships and aircraft which later disappeared give us evidence of problems with navigational instruments. Similar stories are told by officers who were on duty on planes and ships which finally managed to come through the Triangle without disaster. Second, the weather in this part of the Atlantic Ocean is very unpredictable. Dangerous storms that can cause problems even for experienced pilots and sailors can begin suddenly and without warning. Finally, the Bermuda Triangle is very large, and many people, both experienced and inexperienced, sail and fly through it. Perhaps the figure of 1,000 deaths in thirty years shocks some people, but, in fact, the figure is not unusual for an area of ocean that is so large and that is crossed by so many ships. The evidence which exists, therefore, supports one conclusion about Bermuda Triangle: We do not need stories about people from space or strange unnatural powers to explain the disappearances.1. What is the passage mainly about? ______

单选题. Doctors are to begin a trial of a drug treatment that could double the time transplanted organs survive in the body. The 20-minute procedure effectively coats donor organs in a protective shield that stops them being rejected by the patient's immune system. The treatment is expected to prolong the time that organs remain healthy in patients' bodies and also increase their shelf-life (保存期限), so they can be stored for longer or transported further before being used. If the treatment works, it could ease the burden on organ transplant services, which face an increasing gap between the supply and demand for donor organs. People who receive transplants must take drugs to suppress their immune systems, but the body still reacts enough to cause transplants to fail sooner than they should. A healthy transplanted kidney lasts on average only 10 years, around one third of the time it should last. Organs such as hearts and livers fail even sooner. The consequence is that patients who have had one donor organ often need another. The new treatment, developed by researchers at King's College London, is based on the defense mechanism healthy organs use to shield themselves from immune system. Studies suggest the procedure could extend the life of an implanted kidney by around seven years. The scientists believe the treatment will also extend the shelf-life of donor organs, increasing the time they survive outside the body from no more than 24 hours to several days. This could reduce wastage and double the number of organs that work properly once they are transplanted, doctors said. In early tests, only a fifth of organs worked properly after being stored on ice for 16 hours, compared with 50% of those treated with mirococept (药物：米罗西普). A recent pilot study of the treatment on 16 patients found it was safe to use. Patients who receive donated organs treated with mirococept will still need to take drugs to suppress their immune systems, but doctors said an aim of their research was to see if the use of current drugs, which can increase a patient's risk of cancer, can be reduced.6. What is the purpose of the drug treatment mentioned in the passage? ______

单选题. The close relationship between poetry and music scarcely needs to be argued. Both are aural modes which employ rhythm, rime, and pitch as major devices; to these the one adds linguistic meaning, connotation, and various traditional figures, and the other can add, at least in theory, all of these plus harmony, counterpoint, and orchestration techniques. In English the two are closely bound historically. Anglo-Saxon heroic poetry seems certainly to have been read or chanted to a harpist's accompaniment; the verb used in Beowulf for such a performance, the Finn episode, is singan, to sing, and the noun gyd, song. A major source of the lyric tradition in English poetry is the songs of the troubadours. The distance between the gyd in Beowulf and the songs of Leonard Cohen or Bob Dylan may seem great, but is one of time rather than aesthetics. The lyric poem as a literary work and the lyrics of a popular song are both still essentially the same thing: poetry. Whether the title of the work be Gerontion, or Hound Dog, our criteria for evaluating the work must remain the same. The most important prerequisite for both a significant poem and significant lyrics in a popular song is that the writer be faithful to his own personal vision or to the vision of the poem he is writing. Skill and craft for writing poetry are indeed necessary because these are the only means by which a poet can preserve the integrity of this vision in the poem. A poet must not, either because of lack of skill or because of worship of popularity, wealth, or critical acclaim, go outside of his own or his own poem's vision—on pain of writing only the derivative or the trivial. Historically, the writers and singers of the lyrics of popular songs have seemed often to be incapable of personal vision, and to have confused both originality and morality with a servile compliance to popular taste.11. According to the writer, the relationship between poetry and music ______.
