【正文】 Plant breeding is the science of changing the characteristics of plants in order to produce desi。 【點評】本題考點涉及細節(jié)理解,推理判斷,詞義猜測和主旨大意四個題型的考查,是一篇科技類閱讀,要求考生在捕捉細節(jié)信息的基礎上,進一步根據(jù)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??芍疚闹黝}是“衛(wèi)星首次收集太空垃圾”。根據(jù)第二段中的”The test, which was carried out this week, is widely believed to be the first successful demonstration of space cleanup technology, experts told CNN. And it symbolizes an early step toward solving what has already been a critical issue: junk in space.“專家告訴CNN,本周進行的這次測試被廣泛認為是太空清潔技術的首次成功演示。故選B??芍?,“挑戰(zhàn)在于說服有關當局贊助這些任務。 (3)考查詞義猜測。”可知,RemoveDEBRlS衛(wèi)星是通過撒網(wǎng)把垃圾帶離軌道。根據(jù)第六段中的“...,said that an operational version of the RemoveDEBRlS technology would cast a net that remains fastened to the main satellite so the debris can be dragged out of orbit. It could target large pieces of junk, including dead satellites up to 10 meters long.“該公司表示,一種操作性版本的RemoveDEBRlS技術將會在主衛(wèi)星上撒網(wǎng),這樣碎片就可以被拖出軌道。故選C。根據(jù)第一段中“...,imitating a technique that could one day collect spaceborne garbage.”模仿一種有一天可以收集太空垃圾的技術。”一種名為“清除碎片”的實驗清理設備成功地在一顆虛擬衛(wèi)星周圍撒網(wǎng),模仿一種有朝一日可能收集太空垃圾的技術。Why the RemoveDEBRIS Satellite Is InventedD.The RemoveDEBRIS Project Is PerfectB.Provide.(4)What39。Oppose.Support.Acplish.By dragging satellites up to 10 meters long.D.By throwing a net to take the junk from orbit.B.D.Collecting wastes existing in space.B.Demonstrating space technology. There are still enormous barriers to clear before operational cleanup tasks are underway, he said, and the most discouraging is figuring out how to fund such projects.The RemoveDEBRIS satellite will conduct a few more experiments in the ing months, including testing navigation features that could help guide the satellite to a specific piece of debris.Jonathan McDowell, an astrophysicist at the HarvardSmithsonian Center for Astrophysics, said the success of this week39。 s ArianeGroup.The RemoveDEBRIS experiment is run by a pany and researchers led by the U. K.39。 Millions of pieces of junk are turning around in orbit the result of 50 years of space travel and few regulations to keep space clean. At orbital speeds, even a small bit of paint crashing with a satellite can cause critical damage. An experimental cleanup device called RemoveDEBRIS has successfully cast a net around a dummy (仿真的) satellite, imitating a technique that could one day collect spaceborne garbage. 【點評】本題考點涉及推理判斷題型的考查,是一篇科研類閱讀,要求考生根據(jù)上下文進行分邏輯推理,從而選出正確答案。由此可知本文屬于科普文章。為了證實是否可能,研究人員養(yǎng)了18只這種鵝,并在大型風洞中訓練它們飛行。 (4)考查推理判斷。s not clear whether these adaptations alone are what make it possible to fly the 8 hours it takes to climb over Mount Everest. 可知,目前尚不清楚的是,只有這些適應性變化能否可以飛行8小時爬上珠穆朗瑪峰。 (3)考查推理判斷。這兩處綜合推斷出,鵝可以在最低濃度的氧氣中生存。s heart rate and frequency of wing beats remained the same even as their metabolic rate dropped....the researchers report today in elife. This cooling likely helps p可知 風洞實驗表明,當氧氣濃度最低時,鵝的心率和翅膀搏動頻率保持不變,即使它們的新陳代謝率下降。 (2)考查推理判斷。由此可推斷出研究人員飼養(yǎng)這種鵝是為了證實這種鵝是否能飛過珠峰。再根據(jù)最后一段中的So it39。根據(jù)第一段中的In 1953, a mountain climber reported seeing a barheaded goose soar over the peak of Mount Everest. It was thought impossible. 報道說,一名登山者看到一只斑頭鵝飛過珠穆朗瑪峰。結果發(fā)現(xiàn)這種鵝可以在氧氣極低的情況下飛行,但停留時間只有幾分鐘,因此能否飛過珠峰尚不明確。D.C.B.Whether they can manage to fly 8 hours to climb over Mount Everest.(4)Where does the text most probably e from? A.Whether they have muscles pumped more oxygen to.C.It shows the geese could fly at high altitude for long.(3)What still puzzles scientists about the geese? A.The geese managed to breathe less when their blood decreased.C.To see how many calories they burned per hour.(2)What can we learn from the wind tunnel experiment? A.To confirm they could fly over Mount Everest.C.s not clear whether these adaptations alone are what make it possible to fly the 8 hours it takes to climb over Mount Everest. But those few minutes showed these geese really could fly over the top of Mount Everest.(1)Why did the researchers raise 19 barheaded geese and train them? A.s heart rate and frequency of wing beats remained the same even as their metabolic rate dropped. Somehow, the birds managed to cool down their bloodthe measured blood temperature dropped so it could take in more oxygen, the researchers report today in eLife. This cooling likely helps pensate for the very thin air, the team says. Birds already have a better heart and lungs than mammals for sustained physical activity. And researchers knew that barheaded geese have even larger, thinner lungs that let them breathe more deeply and an even bigger heart to pump more oxygen to muscles than other birds. In 1953, a mountain climber reported seeing a barheaded goose soar over the peak of Mount Everest (珠穆朗瑪). It was thought impossible. Now researchers who raised 19 of the geese—named for the black stripes on the backs of their heads—have shown the birds really fly so high. 【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(jù)上下文進行邏輯推理,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A。 (3)考查細節(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
