Ⅲ.阅读理解
(2013·江西九校联考)
Around 200 millio ( http: / / www.21cnjy.com )n years ago, the earth was 18 degrees warmer than it is now. That might be a bit hot for humans, but it was just right for the giant dinosaurs that wandered about the earth during the 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)．www-2-1-cnjy-com
The study, publi ( http: / / www.21cnjy.com )shed in science journal Current Biology, focused on sauropods, long necked herbivores (食草动物) that munched (用力咀嚼) 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 the atmosphere.
Plant eaters natu ( http: / / www.21cnjy.com )rally 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 9 15 years, which warms the atmosphere.
Today, some ( http: / / www.21cnjy.com ) animals, such as cattle, goats and sheep, produce large amounts of methane as a by product 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, according to the Environmental Protection Agency.
The researchers ( http: / / www.21cnjy.com ) 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 man made sources. However, the researchers warn that their numbers are estimates based on multiple assumptions about the digestive systems and populations of dinosaurs.
The author of the stud ( http: / / www.21cnjy.com )y 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 from volcanoes, swamps, shallow seas and so on. Still, Wilkinson says，“ The amount of methane from dinosaurs is large enough to have a measurable effect.”
文章大意：一项研究发现，中生代全球变暖很可能是因为恐龙释放出了大量的甲烷。

D．Food is being processed in the factory.

4．How does the author make his writing reliable
A．By listing some facts.
B．By making predictions.
C．By citing figures.
D．By using mind pictures.
答案：C　推理判断题。作者在文中多次引用数字，以提高文章内容的可信度。
