Passage FiveSome people hate everything that is modern. They cannot imagine how anyone can really like modern music; they find it hard to accept the new fashions in clothing; they think that all modern painting is ugly; and they seldom have a good word for the new buildings that are being built everywhere in the world. Such people look for perfection in everything, and they take their standards of perfection from the past. They are usually impatient with anyone who is brave enough to experiment with new or to express himself or the age in materials original ways. It is, of course, true that many artists do not succeed in their work and instead produce works that can only be considered as failures. If the work of art is a painting, the artist's failure concerns himself alone, but if it is a building, his failure concerns others too, because it may damage the beauty of the whole place. This does sometimes happen, but it is completely untrue to say, as some people do, that modern architecture is nothing.We can't judge every modern building by the standards of the ancient time, even though we admire the ancient buildings. Technologically, the modern buildings are more advanced. The modern architect knows he should learn from the ancient works, but with his greater resources of knowledge and materials, he will never be content to imitate the past. He is too proud to do that.51. Some people hate everything that is modern because ______.A. they are agedB. they find it hard to accept modern thingsC. they take their standards of perfection from the GreekD. they look at things by the standards of the past

Unpopular Subjects?Is there a place in today's society for the study of useless subjects in our universities? Just over 100 years ago Fitzgerald argued in a well-written letter_______(1)Nature that"Universities must be allowed to study useless subjects一_______(2)they don't, who will?" He went on to use the_______(3) of Maxwell's electrodynamics（电动力学）as one case where a"useless subject"has been transformed to a useful subject.Nowadays this argument is again very much_______(4)in many universities. Indeed one suspects that it is one of those arguments that must be_______(5)anew （重新）by each generation. But now there is an added twist（歪曲）一subjects must not only be useful,they must also be_______(6)enough that students will flock（蜂拥） to do them,and even flock to pay to do them.As universities become commercial operations,the pressure to_______(7)subjects or departments that are less popular will become stronger and stronger. Perhapsthis is most strongly_______(8)at the moment by physics.There has been much_______(9)in the press of universities that are closing down physics departments and incorporate them with mathematics or engineering departments.Many scientists think otherwise.They see physics as a_______(10)science, which must be kept alive if only to_______(11)a base for other sciences and engineering.It is of their great personal concern that physics teaching and research is under _________(12)in many universities.How can it be preserved in the rush towards commercial competition? A major turnaround（转变）in student popularity may have to ________(13)until the industrial world discovers that it needs physicists and starts paying them well.Physics is now not only unpopular;it is also"hard".We can do more about the latterby_______（14) teaching in our schools and universities. We can also_______(15)cooperative arrangements to ensure that physicists keep their research and teaching up to date._________(15)A:fix B:modify C:review D:develop

第二篇The Magic of SoundMusic is one of the most beautiful forms of artistic expressions ever invented.In movies and plays, music has an added function:it not only moves people but also can shock people.Our eardrums can withstand sound within 20 to 80 decibels（分贝）.Once sound exceeds this limit , even beautiful music will become ear-splitting noise and harm health.A strong blast（响声）of high sound can twist and break a solid iron sheet.High sound of 150 decibels can kill a healthy rat.In movies,sometimes the hero can produce a sound that ordinary people can't hear and only those whohave the same ability can feel.In nature,there is actually sound that is beyond our hearing.In physics,the sound that exceeds 20,000Hz is called ultrasonic（超音波的）.Dolphins, whales and bats can make such high-frequency sound.It does no harm to health.Sound less than 20Hz is called infrasonic（次声）waves.When we move, the air will vibrate.The vibration of air can produce infrasonic waves.As the frequency of infrasonic waves is close to that of people's internal organs, infrasonic wave may cause resonance（共振）in human bodies.As a result,people's vision may weaken and internal organs may rupture（断裂）.However,whether an infrasonic wave can be used as a weapon depends on its intensity.If its intensity is very low,it won't damage internal organs or a person's health.If the intensity of infrasonic wave exceeds 160 decibels,it is extremely harmful.When wind blows at a force of 3 or 4 over the sea,it will produce infrasonic waves of several decibels.Only typhoons can produce infrasonic waves of over 100 decibels.At present,scientists can only produce infrasonic weapons in the lab with the help of advanced scientific tools and powerful electric power.It is true that the sound______.A:of nature is the most beautifulB:over 80 decibels is harmful to peopleC:of high intensity benefits animalsD:in movies is pleasing to the ear

问答题And if the weather is used to make political points, then so of course, is clothing. The one essential and multipurpose item of clothing for modern Britain is, of course, denim jeans. Worn by everyone outside working hours from royalty to the woman in the street, jeans are the symbol of a casual and classless approach to life. In the informal environments of universities the only suits are worn by administrators—hence the pejorative name for these bureaucrats as “the suits”. Everyone else from professor to undergraduate can be seen carrying out their tasks in blue denim in various states of repair. The most fashionable young men and women will be seen in jeans that are either far too big or far too small for them, with holes, patches, badges, sequins or drawings on them. However, most of us prefer our jeans plain, draught proof and comfortable!
