We can make all the jokes we want about taking baths ourselves, but if we are ill in bed and can't get up, we'll be thankful to the nurses who help us get clean. While I am not a nurse, and have never given anyone a bath, I would imagine that it would take a lot of sympathy (同情) and patience to do so.
Yet those who attended the International Conference on Intelligent Robots and Systems last month were introduced to Cody, a robot that can bathe human beings.
The robot has a base that can be turned to all directions, two human?like arms, and movable wrists (腕). It uses a camera to locate parts of the human body. It then uses bath gloves to clean with a little pressure.
The robot was designed at the Georgia Institute of Technology. Charles Kemp of the Healthcare Robotics Lab is the senior researcher for the project. In a test run, Cody was able to remove 96% of a test subject's dirt—not bad for a robot.
But don't go asking for Cody yet—he's still a model. Yet researchers believe that one day Cody may take the place of nurses for this task. Researchers say that Cody will give patients dignity and protect their personal information. I suppose that would depend on the patient. I'm not sure whether a robot using a camera would make me feel very dignified.
Even so, I can appreciate the need. We don't have enough nurses to go around, and those places that are the most short?handed, for example, nursing homes, are those that have the most patients who are unable to bathe themselves. Still, before I get there, I hope they think of a better way to solve the problem.
1.The writer thinks bathing others must ________.
A.be a lot of fun
B.make you feel thankful
C.take a lot of patience
D.make you feel dignified
2.What is the third paragraph mainly about?
A.Why and where Cody was designed.
B.What Cody looks like and who designed it.
C.What Cody can do and where it will work soon.
D.How Cody works and what has made that possible.
3.We know from the fourth and fifth paragraphs that ________.
A.Cody can bathe patients better than a real nurse can
B.robots like Cody are being produced in large numbers right now
C.Cody can take the place of nurses completely in hospitals
D.researchers think Cody can protect patients' personal information
4.There is a need for Cody because ________.
A.people are becoming lazier
B.it can bring down the cost of nursing
C.there are not enough nurses
D.there are too many nursing homes
5.In the writer's opinion, Cody is ________.
A.a(chǎn)cceptable but not perfect
B.strange but not creative
C.clever and strong
D.lovely and careful

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 (食草動(dòng)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(鷹), 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.
C. Animals destroy their natural resources.
D. Animals create many problems.
2.Animals are important to us mainly because ______.
A. they give us a source of food
B. they are beautiful and lovely
C. they keep the balance of nature
D. they give us a lot of pleasure
3.Which of the following is NOT true?
A. People care much about animals because they need them.
B. Once a certain kind of animal is gone forever, there will never be any more.
C. Killing all rats and mice may cause some new problems.
D. People must not kill any animal or plant.
