Can animals be made to work for us? Some scientists think that one day animals may be taught to do a number of simple jobs. They say that in a film or on TV .We may see elephants, or monkeys, dogs, bears, or other animals doing a lot of things. If you watch carefully, you may find that those animals are always given something to eat in return(作为回报) for doing them. The scientists say that many different animals may be taught to do a number of simple jobs if they know they will get something to eat in return.
Of course, as we know, dogs can be used to guard a house, and elephants can be used to do some heavy jobs. And we can also teach animals to work in factories. Apes(猿猴), for example, have been used in America to help make cars and scientists believe that these large monkeys may one day get in crops(收割庄稼) and even drive trains.

Plants are flowering faster than scientists predicted(预测)in reaction to climate change, which could have long damaging effects on food chains and ecosystems.
Global warming is having a great effect on hundreds of plant and animal species around the world, changing some living patterns, scientists say.
Increased carbon dioxide(CO2)in the air from burning coal and oil can have an effect on how plants produce oxygen, while higher temperatures and changeable rainfall patterns can change their patterns of growth.
“Predicting species’ reaction to climate change is a major challenge in ecology,” said the researches of several U.S. universities. They said plants had been the key object of study because their reaction to climate change could have an effect on food chains and ecosystem services.
The study, published on the Nature website, uses the findings from plant life cycle studies and experiments across four continents and 1,634 species. It found that some experiments had underestimated(低估)the speed of flowering by 8.5 times and leafing by 4 times.
“Across all species, the experiments under-predicted the speed of the advance — for both leafing and flowering — that results from temperature increases,” the study said.
The design of future experiments may need to be improved to better predict how plants will react to climate change, it said.
Plants are necessary for life on the Earth. They are the base of the food chain, using photosynthesis(光合作用)to produce sugar from carbon dioxide and water. They let out oxygen which is needed by nearly every organism on the planet.
Scientists believe the world’s average temperature has risen by about 0.8℃since 1900, and nearly 0.2℃ every ten years since 1979.
So far, efforts to cut emissions(排放)of planet-warming greenhouse gases are not seen as enough to prevent the Earth heating up beyond 2℃ this century — a point scientists say will bring the danger of a changeable climate in which weather extremes are common, leading to drought, floods, crop failures and rising sea levels.
小题1:What is the key information the author wants to give in Paragraph 1?
A.Plants’ reaction to weather could have damaging effects on ecosystem.
B.The increasing speed of flowering is beyond scientists’ expectation.
C.Climate change leads to the change of food production patterns.
D.Food chains have been seriously damaged because of weather.
小题2:We can learn from the study published on the Nature website that ______.
A.plants’ flowering is 8.5 times faster than leafing
B.there are 1,634 plant species on the four continents
C.scientists should improve the design of the experiments
D.the experiments failed to predict how plants react to climate change
小题3:Scientists pay special attention to the study of plants because _______.
A.they can prove the climate change clearly
B.they are very important in the food chains
C.they play a leading role in reducing global warming
D.they are growing and flowering much faster than before
小题4:What can be inferred from the last two paragraphs about the world’s temperature?
A.It has risen nearly 0.2℃ since 1979.
B.Its change will lead to weather extremes.
C.It is 0.8℃ higher in 1979 than that of 1990.
D.It needs to be controlled within 2℃ in this century.
The boss of an Australian restaurant is tired of the waste left by customers. He has required them to eat      on their plates or they’ll be fined and won’t be allowed to       next time.
Chef Yukako Ichikawa has introduced a 30 percent discount for customers who eat all the food they have ordered at Wafu, her      restaurant which is not far from Sydney.
"To contribute to      a future which can continue to develop, we require a little       of our guests than most other restaurants," she says and she has put up a list of her rules on the door to the restaurant .
This list includes finishing all dishes ordered which are free of milk, sugar and eggs and the cook and all her workers tell people who don't      their plates to choose       restaurant next time.
"      your meal means that everything is eaten       lemon slices, ginger(生姜) and wasabi," says the menu.
"Please also pay attention to that vegetables and salad on the      are not decorations(装饰品); they are       of the meal too."
Wafu's strict rules have been      by some but against by some reviewers. Ichikawa insists on it.
"Wafu is not just a restaurant; it is also the      of Yukako's personal qualities ," says a statement on the restaurant's website.
“We not only serve meals and respect the body       prevent waste. We have       to protect the environment and keep the healthy development of our earth.”

Do you still get free plastic bags from the supermarkets? Things have changed.
China has banned (禁止) free plastic bags at shops and supermarkets, and people have to pay for using plastic bags. The rule started on June 1. It came because our country tried to make litter less. Making super-thin (超薄) plastic bags has also been banned.
The Chinese once used about 3,000,000,000 plastic shopping bags a day, and they have caused pollution of the environment. The bags have become a main cause of plastic pollution because they are easy to break and people throw them away here and there. So the Chinese people are encouraged to bring theft own bags for shopping.
What kind of shopping bag is the best to bring? Some students in Chongqing have a good idea. They make their own shopping bags. They use old clothes to make cloth bags, and send them to their parents as presents. They also ask theft parents and friends to use cloth bags instead of plastic ones. They think it is their duty to protect the environment.

For a long time, humans have used technology (科技) to study the world around us, and Mars is the latest place we’re using machines to explore. Besides the earth, the “red planet” is seen, as the one place in our solar system most likely to have life.
Early last month, the first American robot, Spirit, landed on Mars without any problem. Opportunity, the second robot, landed on the planet more than a week ago. Scientists are very excited about these machines’ safe landing on Mars. It means that now we have an excellent chance to look for water and other signs of life. So far, the robots have found some stones that could show Mars was once a wet and warm planet.
But the trips made by Spirit and Opportunity were dangerous. Mars is often called the “death planet”, because in the past its environment has been unfriendly to the robot explorers. Before Spirit and Opportunity, nearly forty spaceships had been sent to Mars since the 1960s. Two-thirds of them failed. The first spaceship, Korabl, sent in 1962 by Russia was among them. It broke apart (分裂) near the earth.
小题1:For a long time humans think ________.
A.they can surely find life on Mars
B.there may be life on Mars
C.it’s too late for them to explore Mars now
D.Mars is the only planet that has life on it
小题2:The two robots ________.
A.have found out that it is warm and wet on Mars
B.were sent to Mars to find some stones
C.were the first two American robots that landed on Mars
D.are the only machines that have landed on Mars so far
小题3:The third paragraph mainly tell us ________.
A.it’s a very hard and dangerous trip for spaceships to Mars
B.two-thirds of the spaceships sent to Mars have failed
C.Spirit and Opportunity landed on Mars successful
D.Mars is called the “death planet”
小题4:From this passage we learn that ________.
A.the two robots have found water on Mars
B.Opportunity touched on Mars a week later than Spirit
C.it’s exciting to have the chance to look for signs of life on Mars
D.Korabl was the first Russian machine to land on Mars
A fish that lives in America can live out of water for months at a time, similar to how animals got used to land millions of years ago, a new study shows.
The Mangrove Rivulets, a kind of little fish, lives in small pools of water. When their living place dries up, they live on the land, said Scott Taylor, a researcher in Florida.                        
The fish can grow as large as three inches. They group together and breathe air through their skin before they can find water again.
The new scientific discovery came during a trip.
“We were travelling for fun. and one day I kicked over a log (圆木) and the fish came out.” Taylor told reporters by telephone. He said he would make his study on the fish known to the public in an American magazine early next year.
In lab tests, Taylor said he found the fish can live up to 66 days out of water without eating.
Some other fish can live out of water for a short period of time. The walking catfish found in Southeast Asia can stay on land for hours at a time, while lungfish (肺鱼) found in Australia, Africa and South America can live out of water, but only in a not active (活波的) way. But no other known fish can be out of water as long as the Mangrove Rivulets and keep active, according to Patricia Wright, a biologist at a Canadian University.&科
More studies of the fish may tell how animals changed over time.
“These animals live in conditions similar to those millions of years ago, when animals began to move from water onto land.” Wright said.
