　　2017西安市高考英语三轮冲刺选练11 阅读理解。Now scientists believe that global warming affects hibernating animals, causing them to wake up earlier. While this may seem a little concern, it is in fact a significant environmental problem. The shortened hibernation period could actually lead to significant declines in the population of several species. Some of the first concrete evidence of the phenomenon came from Colorado, where researchers at the Rocky Mountain Biological lab have been observing marmot(旱獭)hibernation behavior since the 1970s. In the early days of their studies, marmots generally hibernated several weeks into the month of May. Nowadays, however, temperatures in the area have risen by 2. 5 degrees Fahrenheit, and the marmots wake up about a month earlier. At least the marmots are still hibernating. Several other animals have not been hibernating at all recently. Brown bears in the Spanish Cantabrian Mountains did not hibernate last year. In parts of the United States, chipmunks(花鼠)also skipped the hibernation period. The bears seem to have survived without losing many individuals. The chipmunks, however, were not so lucky. Many of the animals died of starvation during the winter. The problem with animals waking up early, or skipping hibernation altogether, lies with the creatures’ metabolism(新陈代谢). When the animals hibernate, their metabolism drops significantly. The animals’ heart rate slows, and they require very little energy to live. When the animals awake from their winter slumber, their metabolism returns to normal. But while their metabolism may be as active as it was before hibernation, food sources aren’t as available as they were before. A marmot may wake up when temperatures get warmer, thinking it’s spring, but plants will not have got the amount of sun they need to signal their spring period of growth. So until the plants grow, the marmots have no reliable food source. Many scientists believe the problem will continue to get worse. In addition to changes in hibernation patterns, some believe that other animals will also begin to change their migration patterns or begin to give birth earlier. For many biologists, that’s a scary prospect. Terry Root, an animal expert at Stanford University, said, “I do think what we will be facing is the extinction of many species. ” 【文章大意】全球变暖带来的连锁反应是多方面的, 其中之一就是导致一些冬眠动物的冬眠期缩短, 这会给这些动物带来巨大的影响。 1.

We can see its light and feel its warmth. The Sun is the major source of evaporation (蒸发) of water from the oceans and lakes. Sunlight also provides the energy used by green plants to make their own food. These green plants then provide food for all organisms (生物) on the Earth. Much of the energy that comes from the Sun never reaches the Earth’s surface. It is either reflected or absorbed by the gases in the upper atmosphere. Of the energy that reaches the lower atmosphere, 30% is reflected by clouds or the Earth’s surface. The remaining 70% warms the surface of the planet, causes water to evaporate, and provides energy for the water cycle and weather. Only a tiny part, approximately 0.023%, is actually used by green plants to produce food. Many gases found in the atmosphere actually reflect heat energy escaping from the Earth’s surface back to the Earth. These gases act like the glass of a greenhouse in that they allow energy from the Sun to enter but prevent energy from leaving. They are therefore called greenhouse gases. When sunlight strikes an object, some of the energy is absorbed and some is reflected. The amount reflected depends on the surface. For example, you’ve probably noticed how bright snow is when sunlight falls on it. Snow reflects most of the energy from the Sun, so it contributes to the low temperatures of winter. Dark-coloured surfaces, such as dark soil or forest, absorb more energy and help warm the surrounding air. 6. Which of the following are forms of the Sun’s energy? A. Sunlight and its heat. B. Evaporation and cycle of water. C. Greenhouse gases and greenhouse glasses. D. White snow and dark forests. 7. According to the passage, the root cause for weather changes on the Earth is ______. A. the atmosphere surrounding the Earth B. water from oceans and lakes C. energy from the Sun D. greenhouse gases in the sky 8. Only a small part of the Sun’s energy reaches the Earth’s surface because most of it is ______. A. absorbed by the clouds in the lower atmosphere B. reflected by the gases in the upper atmosphere C. lost in the upper and lower atmosphere D. used to evaporate water from the oceans and lakes 9. Greenhouse gases ________ so that they warm the surface of the Earth. A. help green plants to produce food B. reflect heat energy escaping from the Earth’s surface back to the Earth C. allow energy from the Sun to enter the atmosphere D. prevent energy from the Sun from leaving the atmosphere 10. We learn from the passage that ________. A. all living things on the Earth depend on the Sun for their food B. a forest looks dark in winter because it absorbs solar energy C. only 0.023% of the energy from the Sun is made use of on the Earth D. greenhouse gases allow heat energy to escape from the Earth’s surface 【参考答案】B篇： ACCBA 阅读理解。 Shopping is not as simple as you may think! There are all sorts of tricks at play each time we reach out for that particular brand(品牌) of product on the shelf. Colouring, for example, varies according to what the producers are trying to sell. Health foods are packaged (包装) in greens, yellows or browns because we think of these as healthy colours. Ice cream packets are often blue and expensive goods, like chocolates, are gold or silver. When some kind of pain killer was brought out recently, researchers found that the colours turned the customers off because they made the product look weak and ineffective . Eventually, it came on the market in a dark blue and white package—blue because we think of it as safe, and white as calm. The size of a product can attract a shopper. But quite often a bottle doesn’t contain as much as it appears to. It is believed that the better-known companies spend, on average,70 per cent of the total cost of the product itself on packaging! The most successful producers know that it’s not enough to have a good product. The founder of Pears soap, who for 25 years has used pretty little girls to promote (推销) their goods, came to the conclusion: “Any fool can make soap, but it takes a genius(天才) to sell it.” 11 Which of the following may trick a shopper into buying a product according to the text? A. The cost of its package. B. The price of the product. C. The colour of its package. D. The brand name of the product. 12.The underlined part “the colours turned the customers off”(in Para.3 ) means that the colours_____________. A. attracted the customers strongly B. had weak effects on the customers C. tricked the customers into shopping D. caused the customers to lose interest 13.Which of the following is the key to the success in product sales? A. The way to promote goods. B. The discovery of a genius. C. The team to produce a good product. D. The brand name used by successful producers. 14.According to the passage, which of the following statement is true? Making soap is so easy that any fool in the world can make it. Greens, yellows or silver are considered to be healthy colours. 25 years ago, the founder of Pears soap was a pretty girl herself. The size of a product can have an effect on the shoppers. 15.Which of the following would be the best title for this text? A. Choice of Good Products B. Disadvantages of Products C. Effect of Packaging on Shopping D. Brand Names and Shopping Tricks 【参考答案】C篇： CDADC （2017天津卷）第二节： 书面表达（满分25分）假设你是晨光中学高二(1)班的班长李津， 得知美国学生Chris 作为交换生， 下学期将到你班学习。 请你根据以下提示， 给他写封邮件：表示欢迎介绍与本地生活相关的信息（如天气， 饮食等）介绍本班情况希望Chris做哪些事情， 以增进中美学生之间的了解和友谊注意：请勿提及与考生相关的真实信息。可适当加入细节， 使内容充实，行文连贯。词数不少于100； 开头已给出， 不计入总词数。参考词汇：交换生 exchange student Dear Chris, I’m Li Jin, monitor of Class One, Grade Eleven. 【考点】考察提纲类作文【写作指导】本文属于提纲类短文，要求以李津的口吻给Chris写信，介绍具体情况。所以本文使用一般现在时和第一人称。要点：1.表示欢迎；2介绍与本地生活相关的信息（如天气， 饮食等）；3.介绍本班情况希望Chris做哪些事情，以增进中美学生之间的了解和友谊。写作时不要仅仅对要点进行生硬的翻译，而是要添加些内容，使文章看起来更充实，要组成一篇通顺连贯的短文，一定要有自己添加的内容，以让文章更为丰富。需要注意紧扣文章主题，给出的要点都需要包括，缺一不可。【参考范文】（略） 书面表达假设你是李华, 你们学校政教处围绕乘车安全举办了一次“安全乘车进一言”的班会, 你作为一名学生, 请发表你的观点, 内容可以包括如下要点: 1. 违规乘车的危害; 2. 遵守交通规则的重要性; 3. 作为学生应该如何做。注意: 1. 词数: 100个左右; 2. 可适当增加细节, 以使行文连贯; 3. 文章的开头和结尾已给出, 不计入总词数。 Classmates, That’s all. Thank you. Classmates, Our teachers usually tell us to take vehicles safely on weekends and cross the road carefully, but some of us used to take a cheap vehicle to save money, which will bring many troubles to us, especially safety for life, because this kind of vehicle has some uncertain factors, for example, the drivers may have no driving license, no enough experience to drive and so on. In addition, some of us paid no attention to traffic rules, which may lead to many accidents. Therefore, in order to protect ourselves, we should obey the rules of taking vehicles and go on the bus one by one and also take the bus according to what teachers tell us to. That’s all. Thank you.
