Around 200 million 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)．
The study, published 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 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 9?15 years, which warms the atmosphere.
Today, some 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 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 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 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.”
1.Scientists think dinosaurs may have led to the global warming because ________.
A．they ate everything they found
B．they usually had a good appetite
C．they released a lot of methane
D. there were too many dinosaurs on earth
2.What do we know about dinosaurs from Paragraph 2?
A．Sauropods fed on plants.
B．Sauropods were of medium size.
C．Dinosaurs used to live on trees.
D．Dinosaurs digested food quickly.
3.Which of the following activities doesn't produce methane?
A．Coal is dug out by machine.
B．Trees and flowers are planted.
C．Goats digest grass under the tree.
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.
5.David Wilkinson seems to believe that ________.
A．methane had little effects on the earth
B．many other factors contributed to warm climate
C．other causes for warm climate were worth considering
D．dinosaurs were mainly to blame for global warming

Animals are natural resources that people have wasted all through our history.
Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.
Why should people care? Because we need animals. And because once they are gone, there will never be any more.
Animals are more than beautiful or interesting or a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems.
For example, when farmers killed large numbers of hawks(鹰), the farmers’ stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice. With no hawks to keep down their numbers, the rats and mice multiplied(繁殖) quickly.
Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger.
Quite a few countries have passed laws. These laws forbid the killing of any animal or plant on the danger list. Slowly, the number of some animals in danger is growing.
1.Why do people kill animals?
A. They kill animals for something they need.
B. They kill animals to raise some money.

After ruling the tennis world for almost five years, Roger Federer is adjusting to life at NO.2. But, like any king whose throne has been taken away, the Swiss star is already planning secretly his return to power, beginning at this week’s US Open.
The problem is, many experts think he will never do it. They blame everything from age and tough competition to his racket and psychology.
For years Federer, 27, had enjoyed the view from the top. Competitors saw him as undefeated, and for the most part he was. However, before the 2008 season began, Federer had an illness that stole his strength and clearly affected his play on the court. Ever since, he has struggled to return to form, winning just two of his last 14 tournament
s.
“Twenty-seven is an age when your body starts talking back to you.” tennis great John McEnroe told the New York Times.
Pancho Sefura, another tennis great, noted that Federer is also facing a maturing crop of young talents. “There are too many great players now,” he said, naming Britain’s Andy Murray, 
21, and Latvia’s Ernests Gulbis, 20.
US magazine Sports Illustrated tennis columnist Jon Wertheim suggested that part of Federer’s problem could be his insistence on using a small racket. He says that the smaller head demands ball control. But we see time and again that racket makers try to get players to use a certain stick — one they would like to market to consumers and it has a negative effect the professional game.
Sports psychologist Jim Loehr told the Times that Federer is probably feeling “a sense of doubt” after being considered as undefeated for so long. If Federer is to recover his state of being undefeated, Loehr said he must overcome his doubt. “Federer doesn’t need fame and money. But he has to get better. He has to go to a whole new level. That’s the only way he stays in the game,” he said.
As for beginning his first Grand Slam in ages as the NO.2 seed, Federer said it might be for the best. “Five years almost, I was expected to win every tournament I entered,” he said, “so maybe Rafael Nadal now feels what I had to feel for a very long time. It will be interesting to see how he handles it.”
1.What does the underlined sentence “your body starts talking back to you” in Para.4 mean?
A. Your body often argues with you.
B. You can do whatever you want.
C. Your strength is beginning to decline.
D. You are more easily to have quite terrible diseases.
2.From the passage, we know the main reason why Federer’s throne was taken away is that _____.
A. he is becoming older and older.
B. he insisted on using a small racket.
C. he is facing a maturing crop of young talents.
D. he had an illness that stole his strength.
3.What can be inferred from the passage?
A. Now it is Nadal who has replaced Federer as the No.1tennis player.
B. the racket makers aim at the players’ better performance in games.
C. It is impossible for Federer to return to power.
D. Federer has never won a Grand Slam before.
4.What’s the best title of the passage?
A. Nadal — The No.1 Tennis Player
B. Federer — Always Undefeated
C. State of Mind Plays a Important Role
D. Federer Hopes to Recover His Magic
