阅读理解aa warm drink of milk before bed has long been the best choice for those wanting a good nights sleep. but now a study has found it really does help people nod offif it is milked from a cow at night.researchers have discovered that “night milk” contains more melatonin(褪黑激素),which has been proven to help people feel sleepy and reduce anxiety.the study, by researchers from seoul, south korea, involved mice being fed with dried milk powder made from cows milked both during the day and at night.those given night milk, which contained 10 times the amount of melatonin, were less active and less anxious than those fed with the milk collected during daytime, according to the study published in the journal of medicinal food.night milk quickened the start of sleep and caused the mice to sleep longer.while the effect of cows milk harvested at different time has not been tested on humans up to now, taking melatonin drugs has been suggested to those who are struggling to fall asleep at night.previous studies have also indicated that milk can be excellent for helping sleep because of the calcium content, which helps people to relax.milk is also sugar-free and additive-free with nutritionists recommending skimmed milk as the best choice before bed as it is the least fattening. the more fat you take in before bedtime, the greater burden you will put on your body at night.1.according to the text, the mice fed with daytime milk.a.started sleep more easilyb.were more anxiousc.were less actived.woke up later2.which of the following is true of melatonin according to the text?a.its been tested on mice for ten times.b.it can make people more energetic.c.it exists in milk in great amount.d.its used in sleeping drugs.3.what can be a suitable title for the text?a.night milk and sleepb.fat, sugar and healthc.an experiment on miced.milk drinking and health4.how does the author support the theme of the text?a.by giving examples.b.by stating arguments.c.by explaining statistical data.d.by providing research results.答案1.b2.d3.a4.dbif humans were truly at home under the light of the moon and stars, we would go in darkness happily, the midnight world as visible to us as it is to the vast number of nocturnal(夜间活动的)species on this planet. instead, we are diurnal creatures, with eyes adapted to living in the suns light. this is a basic evolutionary fact, even though most of us dont think of ourselves as diurnal beings. yet its the only way to explain what weve done to the night: weve engineered it to receive us by filling it with light. the benefits of this kind of engineering come with consequencescalled light pollutionwhose effects scientists are only now beginning to study. light pollution is largely the result of bad lighting design, which allows artificial light to shine outward and upward into the sky. ill-designed lighting washes out the darkness of night and completely changes the light levelsand light rhythmsto which many forms of life, including ourselves, have adapted. wherever human light spills into the natural world, some aspect of life is affected. in most cities the sky looks as though it has been emptied of stars, leaving behind a vacant haze(霾)that mirrors our fear of the dark. weve grown so used to this orange haze that the original glory of an unlit nightdark enough for the planet venus to throw shadows on earthis wholly beyond our experience, beyond memory almost. weve lit up the night as if it were an unoccupied country, when nothing could be further from the truth. among mammals alone, the number of nocturnal species is astonishing. light is a powerful biological force, and on many species it acts as a magnet(磁铁). the effect is so powerful that scientists speak of songbirds and seabirds being “captured” by searchlights on land or by the light from gas flares on marine oil platforms. migrating at night, birds tend to collide with brightly lit tall buildings. frogs living near brightly lit highways suffer nocturnal light levels that are as much as a million times brighter than normal, throwing nearly every aspect of their behavior out of joint, including their nighttime breeding choruses. humans are no less trapped by light pollution than the frogs. like most other creatures, we do need darkness. darkness is as essential to our biological welfare, to our internal clockwork, as light itself. living in a glare of our own making, we have cut ourselves off from our evolutionary and cultural heritagethe light of the stars and the rhythms of day and night. in a very real sense, light pollution causes us to lose sight of our true place in the universe, to forget the scale of our being, which is best measured against the dimensions of a deep night with the milky waythe edge of our galaxyarching overhead.5.according to the passage, human beings.a.prefer to live in the darknessb.are used to living in the day lightc.were curious about the midnight worldd.had to stay at home with the light of the moon6.what does “it” (paragraph 1)most probably refer to?a.the night.b.the moon.c.the sky.d.the planet.7.the writer mentions birds and frogs to.a.provide examples of animal protectionb.show how light pollution affects animalsc.compare the living habits of both speciesd.explain why the number of certain species has declined8.it is implied in the last paragraph that.a.light pollution does harm to the eyesight of animalsb.light pollution has destroyed some of the world heritagesc.human beings cannot go to the outer spaced.human beings should reflect on their position in the universe9.what might be the best title for the passage?a.the magic light.b.the orange haze.c.the disappearing night.d.the rhythms of nature.答案5.b6.a7.b8.d9.c第三节 任务型阅读tourism broadens the thinking of the traveler and leads to culture contact between the hosts and guests from far-off places. this can benefit the locals, since tourists bring culture with them.tourism may help to preserve local customs, as when traditional shows, parades, celebration and festivals are put on for tourists. the musicals, plays and serious dramas of london theatres and other kinds of nightlife are largely supported by tourists. such events might disappear without the stimulus of tourism to maintain them.on the other hand, tourism often contributes to the disappearance of local traditions and folk songs. churches, temples and other similar places are treated as tourist attractions. this can be at the expense of their original function: how many tourists want to worship in the middle of a flow of atheist invaders (无神论侵犯者)? who would want to pray while curious onlookers walk back and forth with guide books, rather than prayer books in their hands? tourism may bring other indirect cultural consequences. anxiety which already exists between ancient and more modern ways may be deepened by tourists ignorance of local customs and beliefs. tourists, if not actually richer, often seem more well-off than natives. the former may therefore feel superior, leaving the latter embarrassed about their lifestyles. the result may be an inferior feeling which hardly helps the sense of identity which is so important to regional culture. the poverty of locality can look even worse when contrasted with the comfortable hotel environment where the average life expectancy is 75 years, may well cause anger in sierra leone, where the local population can expect to live to no more than 41 years. the relative prosperity (繁荣) of tourism may encourage crime. in gambia, unemployed young people offer to act as guides in return for money. when the tourism season is over they can no longer get wages that way so that they turn to stealing from the locals. all this affects the local social life and culture badly. culture erosion (侵蚀) can also take place at more unnoticeable levels. greek villagers traditionally prided themselves on their hospitality (好客). they would put up travelers for free, feeding them and listening to their stories. to take money would have been a disgrace. that has changed
