With the development of people’s living condition, more and more people possess their own cars. Some of us think it is good to own a car. For instance, it’s convenient, fast and comfortable means of transportation. Moreover, it shows that people are becoming richer and the country is much more stronger. It also made relative businesses and industries develop faster.
However, others have different opinions, thinking that cars give up waste gases and pollute the environment around. Too much cars will have some bad effects, such as more accidents and crowdedness. Besides, lack parking lots is another big problem.
As far as I’m concerned, we ought to think careful before buying cars. As if we have cars, we may use it less.

Sleep is something we all do. But some people need to sleep more than others. Babies sleep most of the time. Children in school sleep about ten to twelve hours a night. Most adults sleep only seven or eight hours. 1.
All parts of our bodies have to rest after they work.. Our arms need a rest after we lift heavy thing, When we run fast, our legs work hard. They get tired. We have to rest them. Our brains work hard, too. 2. . We can sit quite still and rest our arms and legs. But our brains aren’t resting. They go right on thinking as long as we are awake.
Our brains slow down a bit when we sleep and dream. 3. Instead of thinking wide-awake thoughts, our brains make up dreams. Some dreams are very pleasing. Some are not. Most of the time we forget them when we wake up.
Scientists have tried to find out what would happen if people were not allowed to sleep. They asked some people not to go to bed. The people stayed up all night and all the next day. They stayed up the next night too, and the day after. They played games, but they made mistakes. They forgot things. 4. The people grew rude and mean. They became angry with their friends. Finally they were too tired to stand up. When they sat down, they fell asleep.
Scientists have found that if people are not allowed to sleep and to dream, they act in an unusual way. 5. But we do know that we need it to stay well. So tonight have a good sleep. Lie down under the covers. Shut your eyes. Let your thoughts wander. Soon you’ll stop thinking. You’ll be asleep.
A. It was hard for their tired brains to work.
B. When we are awake, they help us pay attention to the world around us
C. But babies, children, and adults----all of us need to have our sleep
D. Good sleep helps to improve one’s memory
E. No one knows why sleep is so good for us
F. But even as we sleep our brains are doing some work
G. Of course you will have a good sleep
What will power your house in the future？Nuclear，wind，or solar power？According to scientists at the Massachusetts Institute of Technology(MIT)in the US，it might be leaves—but artificial(人造的)ones.
Natural leaves are able to change sunlight and water into energy. It is known as photosynthesis(光合作用)．Now researchers have found a way to imitate this seemingly simple process.
The artificial leaf developed by Daniel Nocera and his colleagues at MIT can be seen as a special silicon chip with catalysts(催化剂)．Similar to natural leaves，it can split water into hydrogen and oxygen when put into a bucket of water. The hydrogen and oxygen gases are then stored in a fuel cell，which uses those two materials to produce electricity，located either on top of a house or beside the house.
Though the leaf is only about the shape of a poker card，scientists claimed that it is promising to be an inexpensive source of electricity in developing countries.“ One can imagine villages in India and Africa not long from now purchasing an affordable basic power system based on this technology，”said Nocera at a conference of the American Chemical Society.
The artificial leaf is not a new idea. The first artificial leaf was invented in 1997 but was too expensive and unstable for practical use. The new leaf，by contrast，is made of cheap materials，easy to use and highly stable. In laboratory studies，Nocera showed that an artificial leaf prototype(原型)could operate continuously for at least 45 hours without a drop in activity.
The wonderful improvements come from Nocera's recent discovery of several powerful，new and inexpensive catalysts. These catalysts make the energy transformation inside the leaf more efficient with water and sunlight. Right now，the new leaf is about 10 times more efficient at carrying out photosynthesis than a natural one. Besides，the device can run in whatever water is available；that is，it doesn't need pure water. This is important for some countries that don't have access to pure water.
With the goal to “make each home its own power station” and “give energy to the poor”，scientists believe that the new technology could be widely used in developing countries，especially in India and rural China.
1.Which of the following orders correctly shows how the artificial leaf is used to produce electricity?
a．artificial leaves split water into hydrogen and oxygen
b．the hydrogen and oxygen gases are stored in a fuel cell
c．the artificial leaves are put in water
d．the fuel cell uses hydrogen and oxygen to produce electricity
A．c，b，a，d B．c，a，b，d
C．b，c，a，d D．c，a，d，b
2.The purpose of the scientists at MIT in developing the new artificial leaf is to________.
A．build up more power stations in the world
B．provide cheaper energy for developing countries
C．offer people in developing countries access to pure water
D．gain a deeper understanding of the photosynthesis process
3.The main idea of this passage is ________.
A．an introduction to the history of artificial leaves
B．an invention copying photosynthesis
C．giving energy to the poor
D．a mixture of water power and solar energy
