【正文】 Joop van Loon, an entomologist at Wageningen University in the Netherlands, told Live Science, Mosquitoes start orienting (使......朝向) themselves。Mosquitoes are especially active in the late afternoon. While flying along, they use their sense of smell to find possible targets. They find victims (攻擊對象) by smelling the carbon dioxide (CO2) breathed out by humans and animals. That39。t tell what your blood type is from a faraway place. Jonathon Day, a professor of medical entomology (昆蟲學(xué)) at the University of Florida in the US, told NBC it39。 mouths water?If this is you, you39。Some people sit outside for hours without getting bitten by mosquitoes, but it always seems like you39。 【點評】本題考點涉及細(xì)節(jié)理解和推理判斷兩個題型的考查，是一篇科普類閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，并根據(jù)上下文進(jìn)行邏輯推理，從而選出正確答案。根據(jù)第四段中的“But heat will disappear over time no matter how good the material around it is, so the team set up a chemical storage system that can keep the energy in a stable molecular configuration. ”但是熱量會隨著時間的推移而消失，不管周圍的物質(zhì)有多好，所以研究小組建立了一個化學(xué)儲存系統(tǒng)，可以將能量保持在一個穩(wěn)定的分子結(jié)構(gòu)中)可推斷，這種分子結(jié)構(gòu)的優(yōu)勢是相對穩(wěn)定。故選A。 （3）考查細(xì)節(jié)理解。根據(jù)第二段中的“thanks to a new material that can store solar energy during the day and release it later as heat. This transparent polymer film could be applied to many different surfaces, such as window glass or clothing. ”多虧了這種能在白天吸熱之后以熱能形式釋放的新型材料，這個透明的聚合物膜可以應(yīng)用于許多不同的表面，如窗戶玻璃或服裝)可知，這種聚合物膜可以吸熱，此后再以熱能的形式釋放出來。故選C。s energy and then releases it as heat to make the ice on the windshield disappear. ”想象一下你的衣服可以釋放足夠的熱量讓你溫暖和舒適，讓你可以在冰冷的房間里保持舒適。 （1）考查推理判斷。Such chemicallybased storage materials, known as Solar Thermal Fuels(STF), have been developed before. But those earlier efforts were designed to be used in liquid solutions and not able to make durable (耐用的) solidstate films. The new approach is the first based on a solidstate material, in this case a polymer, and the first based on inexpensive materials and widespread production technology.（1）What is the main purpose of Paragraph 1? show the main idea of the passage. practice readers39。 s energy through a chemical reaction and releasing it later as heat. According to a team of researchers at MIT, both cases may be possible before long, thanks to a new material that can store solar energy during the day and release it later as heat. This transparent polymer film could be applied to many different surfaces, such as window glass or clothing.Imagine your clothing could release enough heat to keep you warm and cozy, allowing you to stay fortable in a cooler room. Or, picture a car windshield that stores the sun39。 【點評】本題考點涉及推理判斷，詞義猜測和主旨大意三個題型的考查，是一篇科研類閱讀，考生需要根據(jù)上下文的邏輯關(guān)系，進(jìn)行分析，推理，概括和歸納，從而選出正確答案。 （4）考查主旨大意。由此推斷，消極會消耗我們身體的能量，降低對疾病的抵抗力。re happy, but to slow down dramatically when we39。 （3）考查推理判斷。根據(jù)第三段中的 being more focused on the positive things in life in an effort to enhance their immune functioning. 可知老人們更加關(guān)注生活中積極的事物，是為了增強(qiáng)他們的免疫功能。選C。因此，當(dāng)我們的身體需要額外的能量時，（我們的身體）會去找免疫系統(tǒng)。 （1）考查推理判斷。十年前作者與生物學(xué)家羅伯特D.Age, health and happinessC.Being negative drains energy from our body, lowering resistance to disease.（4）Which of the following is the best title of the passage? A.Our ancestors evolved their immune systems in fighting against fierce animals.C. study? A.D.immune function and healthB.brain will satisfy it by sharing optional metabolic output（2）In paragraph 3 this relationship most probably refers to the one between ______. A.organs will speed up metabolic processes to answer itC.re not. With this background in mind, Trivers supposed that older people evolved a strategy of turning this relationship on its head, being more focused on the positive things in life in an effort to enhance their immune functioning. This was helped along by their knowing much more about the world than younger adults, so they can deal with some of the unpleasant things in life more easily.（1）According to Robert Trivers, when our body needs extra energy, ______. A. As a result, our immune system evolved to run in maximum amounts when we39。t need to waste energy making immune cells to fight off tomorrow39。 When our ancestors needed more energy than usual, perhaps while being chased by a tiger, they had to get that energy from somewhere in the body. Could they borrow it from the brain? That organ uses 20 percent of our metabolic (新陳代謝) output, whether we are solving math problems or watching television reruns. Due to this constant energy requirement, borrowing energy from the brain when our need surpasses the available supply is not an option. Perhaps we could borrow energy from our muscles. Because we use far more muscle energy when we are active than when at rest, in principle, we could borrow energy when we are sitting. But the problem is that most of the energydemanding emergencies of our ancestors required a muscular response. There was no way to borrow energy from our muscles during an emergency because relaxing when a tiger showed up was not an effective response. This brings us to our immune system, which, when strong, protects us from many illnesses and diseases. Like the brain, the immune system works at great metabolic cost, but largely in the service of keeping us healthy in the future. We have an enormous number of immune cells coursing through our body, a momentary break from production is fine. So, when our body needs extra energy, one of the places it goes is our immune function. When you39。 Studies show that older people tend to remember the positive things in life rather than the negative things, while younger people remember the positive and negative equally well. The dominant psychological theory to explain this is that older people are aware of their limited time left, so they prioritize positive emotional experiences. But about a decade ago, I worked with biologist Robert Trivers on his idea that there was an evolutionary basis for older people39。 【點評】本題考點涉及細(xì)節(jié)理解，推理判斷和主旨
