D）阅读下面的短文，根据短文内容回答问题。（10分）New rules and behaviour standards(行为规范) for middle school students came out（颁布） in March. Middle schools are going to use a new way to decide who the top students are. The best students won’t only have high marks. The following are some of the new rules.Tell the truth. Have you ever cheated(作弊) in an exam? Don’t do it again! That’s not something honest students should do.Do more at school. Good students love animals and care for other people. April is Birdloving Month in China. Is your school doing anything to celebrate it? You should join! In that way， you can learn more about animals and how to protect（保护） them.Be open to new ideas. Have you ever thought people could live on the moon? Maybe you’ll find another earth in space in the future. Everyone’s new ideas are important.Protect yourself. Has a thief ever taken money from one of your classmates? Don’t let it happen to you. If you have to go back home late， you should let your parents know.Use the Internet carefully. The Internet can be very useful for your study. But some things on the Internet aren’t for kids， so try to look at the good web pages（网页）. You can use the web pages for fun or homework.36. What should the best students do in an exam? _______________________________________________________________--

Smart WindowWindows not only let light in to cut down an electricity use for lighting, but the light coming through the window also provides heat. However, windows are not something people typically associate with being a cutting edge technology. Researchers are now working on new technologies that enable a window to quickly change from clear to dark and anywhere in between with a flip of a switch."It took us a long time to figure out what a window really is," says Claes Granqvist. He's a professor of solid-state physics at Uppsala University in Sweden. "It's contact with the outside world. You have to have visual contact with the surrounding world to feel well. " So, windows and natural light are important for improving the way people feel when they're stuck indoors.Yet, windows are the weak link in a building when it comes to energy and temperature control. In the winter, cold air leaks in. When it's hot and sunny, sunlight streams in. All of this sunlight carries lots of heat and energy. And all of this extra heat forces people to turn on their air conditioners. Producing blasts of cold air, which can feel so refreshing, actually suck up enormous amounts of electricity in buildings around the world.Windows have been a major focus of energy research for a long time. Over the years, scientists have come up with a variety of strategies for coating, glazing, and layering windows to make them more energy efficient. Smart windows go a step further. They use chromogenic technologies which involve changes of color.Electrochromic windows use electricity to change color. For example, a sheet of glass coated with thin layers of chemical compound such as tungsten oxide works a bit like a battery. Tungsten oxide is clear when an electric charge is applied and dark when the charge is removed, that is, when the amount of voltage is decreased, the window darkens until it's completely dark after all electricity is taken away. So applying a voltage determines whether the window looks clear or dark.One important feature that makes a smart window so smart is that it has a sort of "memory. " All it takes is a small jolt of voltage to turn the window from one state to the other. Then, it stays that way. Transitions take anywhere from 10 seconds to a few minutes, depending on the size of the window. The development of smart windows could mean that massive air conditioning systems may no longer need. "In the future," Granqvist says, "our buildings may look different. "Which of the following statements does not indicate the importance of windows as described in the first two paragraphs?A．Windows can change from clear to dark to save energy.B．Windows help to save energy by letting light in.C．Windows help to save energy by providing heat.D．Windows enable people to have contact with the outside world.

Rockets in the SkyIf someone asked you,"What color is the sky?"I expect that you would answer,"Blue."I am afraid that you would be wrong.The sky has no color.When we see blue,we are looking at blue sunlight.The sunlight is shining on little bits of dust in the air.We know that there is air all around the world.We could not breathe without air.Airplanes could not fly without air.They need air to lift their wings.Airplanes cannot fly very high because as they go higher the air gets thinner.If we go far enough away from the earth,we find there is no air.What is the sky?The sky is space.In this space there is nothing except the sun,the moon and all the stars. Scientists have always wanted to know more about the other worlds in the space.They have looked at them through telescopes and in this way they have found out a great deal.The moon is about 384 ,000 kilometers away from the earth.An airplane cann't fly to the moon but there is a thing that can fly even when there is no air. This is rocket.I am sure that you are asking,"How does a rocket fly?"If you want to know,get a balloon and then blow it up until it is quite big.Do not tie up the neck of the balloon.Let go!The balloon will fly off through the air very quickly.The air inside the balloon tries to get out.It rushes out through the neck of the balloon and this pushes the balloon through the air.It does not need wings like an airplane.This is how a rocket works.It is not made of rubber（橡胶）like a balloon,of course.It is made of metal. The metal must not be heavy but it must be very strong.There is gas inside the rocket which is made very hot. When it rushes out of the end of the rocket,the rocket is pushed up into the air.Rockets can fly far out into space.Rockets with men inside them have already reached the moon.Several rockets,without men inside them,have been sent to other worlds much farther away.One day rockets may be able to go anywhere in the space.When an airplane flies too high,______.A:the air will be too thin to support its wingsB:the air will become thickerC:the air will exert pressure on itD:the air will disappear in no time
