单选题A report published recently brings bad news about air pollution. It suggests that it could be as damaging to our health as exposure to the radiation from the 1986 Ukraine nuclear power disaster. The report was published by the UK Royal Commission on Environmental Pollution. But what can city people do to reduce exposure to air pollution? Quite a lot, it turns out. Avoid walking in busy streets. Choose side streets and parks instead. Pollution levels can fall a considerable amount just by moving a few meters away from the main pollution source—exhaust fumes (烟气). Also don't walk behind smokers. Walk on the windward side of the street where exposure to pollutants can be 50 percent less than on the downwind side. Sitting on the driver's side of a bus can increase your exposure by 10 percent, compared with sitting on the side nearest the pavement. Sitting upstairs on a double-decker can reduce exposure. It is difficult to say whether traveling on an underground train is better or worse than taking the bus. Air pollution on underground trains tends to be less toxic than that at street level, because underground pollution is mostly made up of tiny iron particles thrown up by wheels hitting the rails. But diesel and petrol fumes have a mixture of pollutants. When you are crossing a road, stand well back from the curb while you wait for the light to change. Every meter really does count when you are close to traffic. As the traffic begins to move, fumes can be reduced in just a few seconds. So holding your breath for just a moment can make a difference, even though it might sound silly. There are large sudden pollution increases during rush hours. Pollution levels fall during nighttime. The time of year also makes a big difference. Pollution levels tend to be at their lowest during spring and autumn when winds are freshest. Extreme cold or hot weather has a trapping effect and tends to cause a build-up of pollutants.

单选题{{B}}Passage Five{{/B}} The Vikings have left many traces of their settlement which are still visible today. Archaeology provides physical evidence of their conquests, settlement and daily life. The study of place names and language shows the lasting effect which the Viking settlements had in the British Isles, and DNA analysis provides some insights into the effect the Vikings had on the genetic stock of the countries where they settled. All of this provides valuable information, but the only reason that we have an idea of the "Vikings" as a people is their appearance in the written sources. Unfortunately, the value of the written evidence is limited. Not a lot of evidence survives, and much of what we have is either uninformative or unreliable. Many popular ideas about Vikings are nineteenth-century inventions. Others are the result of early historians accepting sources which modern scholars now regard as completely unreliable. In Scandinavia the Viking Age is regarded as part of prehistory because there are practically no contemporary written sources. Even in western Europe, the Viking Age is often seen as part of the "Dark Ages", from which comparatively few historical records have survived. Surviving accounts of Viking activity were almost exclusively written by clergymen (神职人员). These monastic chronicles (编年史) outline broadly what happened, at what date. There are also sources of a more directly religious nature, such as the much-quoted letters of Alcuin, and Wulfstan's famous "Sermon of the Wolf ", both of which chose to interpret the Viking raids as God's punishment on the Anglo-Saxons for their sins. Even the chronicles reflect the fact that the Vikings often attacked monasteries for their wealth, which created an obvious bias against them, and the hostile tone of these contemporary accounts has done much to create the popular image of Viking atrocities. However, modern historians have noted that the same sources show Christian rulers behaving equally unpleasantly, but without being condemned on religious grounds. We tend to think of the Vikings as a race of Scandinavian warriors, but the reality is more complex. Raids on the British Isles and the coasts of France and Spain were the work of Vikings from Norway and Denmark. The word Viking means one who lurks in a "vik" or bay, in effect, a pirate. The word "Viking" has come to describe a whole new age in Europe between about 800 and 1150. This is despite the fact that Vikings were not just pirates and warriors but also traders and colonists. But at the start of the Viking Age in the last decade of the 8th century, loot and adventure were the main goals of the Norwegians who raided in Scotland and Ireland and of the Danes who attacked England. Gold and silver treasures accumulated by the great monasteries could be converted into personal wealth and thus power, and captives could be sold as slaves.

单选题{{B}}Passage Four{{/B}} A metaphor is a poetic device that deals with comparison. It compares similar qualities of two dissimilar objects. With a simple metaphor, one object becomes the other: Love is a rose.Although this does not sound like a particularly rich image, a metaphor can communicate so much about a particular image that poets use them more than any other type of figurative language. The reason for this is that poets compose their poetry to express what they are experiencing emotionally at that moment. Consequently, what the poet imagines love to be may or may not be our perception of love. Therefore, the poet's job is to enable us to experience it, to feel it the same way as the poet does. Let's analyze this remarkably unsophisticated metaphor concerning love and the rose to see what it offers. Because the poet uses a comparison with a rose, first we must examine the characteristics of that flower. A rose is spectacular in its beauty, its petals (花瓣) are nicely soft,and its smell is pleasing. It's possible to say that a rose is actually a feast to the senses of sight,touch, and smell. The rose's appearance seems to border on perfection, each petal seemingly symmetrical in form. Isn't this the way one's love should be? A loved one should be a delight to one's senses and seem perfect. However, there is another dimension added to the comparison by using a rose. Roses have thorns. The poet wants to convey the idea that roses can be tricky.So can love, the metaphor tells us. When one reaches out with absolute trust to touch the object of his or her affection, ouch, a thorn can cause great harm! "Be careful," the metaphor warns: Love is a feast to the senses, but it can overwhelm us, and it can also hurt us and cause acute suffering. This is the poet's perception of love—all admonition (劝诫). What is the point?Just this: It took almost 14 sentences to clarify what a simple metaphor communicates in only four words! That is the artistry and the joy of the simple metaphor.
