【正文】 when our body needs extra energy, one of the places it goes is our immune function.”可知我們的身體里有大量的免疫細胞，暫時停止運作是可以的。因此，當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)。由此可以推斷，免疫系統(tǒng)會暫時停止來為身體提供額外的能量。選C。 （2）考查詞義猜測。根據第三段中的 being more focused on the positive things in life in an effort to enhance their immune functioning. 可知老人們更加關注生活中積極的事物，是為了增強他們的免疫功能。也就是說積極與免疫功能之間有關系，越積極，免疫功能越強，就能活得越久，所有選項中D項（樂觀與壽命）之間最切題，故選D。 （3）考查推理判斷。根據最后一段中的As a result, our immune system evolved to run in maximum amounts when we39。re happy, but to slow down dramatically when we39。re not.可知當我們快樂時，我們的免疫系統(tǒng)進化到最大程度，但是當我們不快樂時，免疫系統(tǒng)會減弱。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。選D。 （4）考查主旨大意。作者開頭提出老年人更關注積極的事情，后文提到積極的情緒會增強免疫系統(tǒng)，所以本文主要講的是年齡，健康與積極的情緒之間的關系，選B。 【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，考生需要根據上下文的邏輯關系，進行分析，推理，概括和歸納，從而選出正確答案。6．閱讀理解 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。s energy and then releases it as heat to make the ice on the windshield disappear. 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. Solar energy is only available about half the time we need it — during daylight. For the sun to bee a major power provider for human needs, there has to be an efficient way to save it up for use during nighttime and stormy days. Most such efforts have focused on storing and recovering solar energy in the form of electricity, but the new finding, by MlI professor Jeffrey Grossman, Postdoc David Zhitomirsky and graduate student Eugene Cho, could provide a highly efficient method for storing the sun39。s energy through a chemical reaction and releasing it later as heat. The key to enabling longterm, stable storage of solar heat, the team said, is to store it in the form of a chemical change rather than storing the heat itself. 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. When exposed to sunlight, the molecules can stay that way for long periods Then, when triggered (觸發(fā))by a very specific temperature or something else, the molecules return to their original shape , giving off heat in the process. 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。 imagination. interest readers in the passage. introduce a new kind of material.（2）According to the passage, what can the polymer film do? can be made into window glass. can make necessary electricity. can store energy and release sunshine. can absorb sunshine and give off heat.（3）According to the passage, what is STF based on? chemical reaction. movement of heat. form of electricity. physical reaction.（4）What is the advantage of the molecular configuration? is less expensive. is very powerful. is easily available. is less changeable.【答案】 （1）C（2）D（3）A（4）D 【解析】【分析】本文是一篇說明文，介紹了一種新型材料，它可以通過自身吸熱并儲存熱量，之后能夠根據需要釋放熱。 （1）考查推理判斷。根據第一段“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。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?；蛘?，再想象一下車的擋風玻璃可以儲存太陽的能量，然后釋放熱量使擋風玻璃上的冰消失)可推測，本段以衣服和騎車擋風玻璃為例，提到了如果衣服能夠吸熱和放熱、汽車的擋風玻璃能夠吸熱和自動除冰那該是多么好的事，以此來吸引對著對本文的興趣。故選C。 （2）考查細節(jié)理解。根據第二段中的“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D。 （3）考查細節(jié)理解。根據最后一段中的“Such chemicallybased storage materials, known as Solar Thermal Fuels(STF), have been developed before. ”這種以化學反應為基礎的儲存材料，即太陽能熱燃料(STF)，以前就已經被開發(fā)出來了，可知，STF是以化學反應為基礎。故選A。 （4）考查推理判斷。根據第四段中的“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，不管周圍的物質有多好，所以研究小組建立了一個化學儲存系統(tǒng)，可以將能量保持在一個穩(wěn)定的分子結構中)可推斷，這種分子結構的優(yōu)勢是相對穩(wěn)定。故選D。 【點評】本題考點涉及細節(jié)理解和推理判斷兩個題型的考查，是一篇科普類閱讀，考生需要準確捕捉細節(jié)信息，并根據上下文進行邏輯推理，從而選出正確答案。7．閱讀理解 Some people sit outside for hours without getting bitten by mosquitoes, but it always seems like you39。re being eaten alive within minutes of stepping outdoors. If this is you, you39。re not alone. According to Smithsonian Magazine, around 20 percent of people in the world are especially tasty to mosquitoes. What about these people makes mosquitoes39。 mouths water? A popular myth claims that mosquitoes prefer certain blood types, but the fact is that they simply can39。t tell what your blood type is from a faraway place. Jonathon Day, a professor of medical entomology (昆蟲學) at the University of Florida in the US, told NBC it39。s not plicated. The two most important reasons a mosquito is attracted to you have to do with sight and smell. 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。s why you monly find them in crowded streets and parks. Joop van Loon, an entomologist at Wageningen University in the Netherlands, told Live Science, Mosquitoes start orienting (使......朝向) themsel
