12、e Mesozoic (中生代的) era. A new study found that plant­eating dinosaurs may have contributed to the warming of the earth by releasing significant amounts of methane (甲烷)The study, published in science journal Current Biology, focused on sauropods, long­necked herbivores (食草动物) that munched (用

13、力咀嚼) on the top of trees. They were the largest of the dinosaurs; food broke down in their stomachs for long periods of time. The researchers estimate that a sauropoda released 2,675 liters of methane per day adding up to a large amount of the greenhouse gas being pumped from dinosaur's gut into

14、 the atmosphere.Plant eaters naturally release methane as part of their digestive process. The larger the animal, the more methane it produces. Methane, a greenhouse gas, traps heat and remains in the atmosphere for approximately 915 years, which warms the atmosphere.Today, some animals, such as cat

15、tle, goats and sheep, produce large amounts of methane as a by­product to their food digestion. Methane is also released from human influenced sources such as landfill, agricultural activities, coal mining and other industrial practices which all contribute to today's climate change, accord

16、ing to the Environmental Protection Agency.The researchers estimate that earth's sauropods would have produced about 520 million tons of methane per year similar to the total amount of methane produced today by natural and man­made sources. However, the researchers warn that their numbers a

17、re estimates based on multiple assumptions about the digestive systems and populations of dinosaurs.The author of the study David Wilkinson says the emission of methane from dinosaurs would have been just one of the causes of warm climate during the Mesozoic era.Other causes include gases produced f

18、rom volcanoes, swamps, shallow seas and so on. Still, Wilkinson says，“The amount of methane from dinosaurs is large enough to have a measurable effect.”1Scientists think dinosaurs may have led to the global warming because_.Athey ate everything they foundBthey usually had a good appetiteCthey releas

21、_.Amethane had little effects on the earthBmany other factors contributed to warm climateCother causes for warm climate were worth consideringDdinosaurs were mainly to blame for global warmingBElectric cars are dirty. In fact, not only are they dirty, they might even be dirtier than their gasoline&#

22、173;powered cousins. People in California love to talk about “zero­emissions (排放) vehicles”， but people in California seem to be_clueless_about where electricity comes from. Power plants most all use fire to make it. Apart from the few people who have their roofs covered with solar cells, we ge

23、t our electricity from generators (发电机). Generators are fueled by something usually coal, oil, but also by heat generated in nuclear power plants. There are a few wind farms and geothermal (地热) plants as well, but by far we get electricity mainly by burning something.In other words, those “zero­

24、;emissions” cars are likely coal­burning cars. Because the coal is burned somewhere else, it looks clean. It is not true. It's as if the California Greens are covering their eyes “If I can't see it, it's not happening.” Gasoline is an incredibly efficient way to power a vehicle; a g

25、allon of gas has a lot of energy in it. But when you take that gas (or another fuel) and first use it to make electricity, you waste a nice part of that energy, mostly in the form of wasted heat at the generator, through the transmission lines, etc.A gallon of gas may drive your car 25 miles. But th

26、e electricity you get from that gallon of gas won't get you nearly as far, so electric cars burn more fuel than gasoline­powered ones. If our electricity came mostly from wind or geothermal, or solar, then an electric car truly would be clean. But for political, technical, and economic reas

27、ons, we don't use much of those energy sources.In addition, electric cars' batteries which are poisonous for a long time will eventually end up in a landfill. And finally, when cars are the polluters, the pollution is spread across all the roads. When it's a power plant, though, all the

28、junk is in one place. Nature is very good at cleaning up when things are not too concentrated, but it takes a lot longer when all the garbage is in one spot.6What's the main idea of the passage?AElectric cars aren't actually clean.BElectric cars are zero­emissions vehicles.CZero­em

32、八十多岁的老人看病过程中得知老人在妻子生病住院期间，尽管妻子已经有五年都不认识他了，但是这位老人仍然坚持每天早上来医院和妻子一起吃早饭。通过这件事让“我”知道真正的爱就是接受所有的一切。1选C根据“it would be at least 40 minutes before someone would be able to see him.”可知在没有轮到看病时，护士让他坐在候诊室等候。本题容易误选D，take a break休息。2选D现在分词作伴随状语：护士让老人坐下等候的同时告诉他轮到他看病至少得要40分钟。3选C根据第一段第二句话这个老人对护士所说的话可知，因为老人很匆忙要赶上9：30

33、 的约会，所以老人在等待过程中不停地看手表。4选Aturn up 意为“到达；出现；露面”；show off 意为“炫耀”；come on 意为“加油”；go away 意为“走开；离开”。根据“我”不忙可知“我”的病人没有在约定的时间到达。5选A根据上文第一段“for an appointment”可知老人在老伴生病期间需要去护理房。6选B根据下文提到的“she” 和“true love”可知是老人的妻子。7选B如果老人约会去迟了，老人的妻子会不会为他而担心，这是人之常情。故选B。8选A由下文“even though she doesn't know who you are ”可知老

34、人的妻子已经有五年都不认识他了。A意为“认出；识别”；B意为“回答”；C意为“相信”；D意为“希望；期望”。9选C当听到老人的话，“我”感到很惊讶。C符合语境。10选B“我”被老人的话所感动，所以“抑制住”自己的眼泪。11选A通过这件事使“我”意识到什么是真正的爱。12选C真正的爱就是对于所有一切的接受。本题点明了文章的主旨，老人不管妻子患病与否都始终不离不弃，所以是接受了一切，无论好坏。13选Anot necessarily 意为“未必；不一定”。这句话的意思是“最幸福的人并不一定是一个拥有所有最好东西的人”。14选Bmake the best of固定短语，意为“充分利用”。最幸福的人不一

35、定非得拥有一切美好的东西，最幸福的人是那些充分利用和把握他们所拥有的一切的人。15选D由上文老人的故事可知生命不在于如何度过风暴，而在于如何在风暴中快乐坚强地品味生活，这才是生活的真谛。.1解析：本句中，one of which引导非限制性定语从句，先行词为aspects of our life，并在从句中作主语。答案：which2解析：changes in climate意为“在气候方面的变化”。答案：in3解析：分析句子结构，此处应使用副词修饰形容词worried，故应填入especial的副词形式especially。答案：especially4解析：根据句中的时间状语since 2008可知，应用现在完成时
