Researchers at Stanford University have developed a new material that can move heat out of buildings and into space. The researchers say the material can cool buildings even on hot days. The cooling material is a very thin sheet with many layers that could be placed on a roof like solar panels(板). However, instead of turning sunlight into energy as solar panels do, the material turns heat into infrared（红外线的）radiation.

Shanhui Fan is an electrical engineering professor at Stanford University. He says that the panels have a layer of material that is like sand. The panels act like a mirror. They take heat out of buildings and reflect the light from the sun. And he says both the heat and sunlight arc sent 100 kilometers into outer space. \structure that cools itself without electricity input, even under the sun. So, what it docs is basically radiate heat to outer space and also reflect the sunlight so it doesn't get heated up by the sun. Mr. Fan says it is like having a window into space. The heat is sent directly into space without increasing the air temperature He says buildings in developing countries that do not have electricity or air

The researchers say the main problem is creating actual cooling systems using the high-tech panels. They say it may be possible to develop a cooling spray(喷涂）that could be used on present solid structures. They believe the cooling spray technology could be developed in the next three to five years. They say as much as 15 percent of the energy used in the United States is spent providing power to air conditioning systems.

32.What is the main idea of paragraph 1?

A. Living on hot days is no longer a big problem now. B. Researchers are developing new solar panels on roofs. C. A new material is created to cool the buildings. D. The new material is a very thin sheet with many layers. 33.According to paragraph2, how does the panel work? A. It takes in the heat and cools it down. B. It uses a mirror to reflect the sunlight. C. It has a window to let out the heat. D. It sends heat away right into space.

34.Which of the following can best describe the advantage of the new panel? A. Convenient but impractical. B. Eco-friendly and energy-saving. C. Effective but expensive. D. Creative and cheap.

35.What can you infer from the passage?

A. The device of the new panel is still under research. B. Some people got benefits from producing the panels.

C. It is impossible to solve the problem of creating actual cooling system. D. The new panels may save 15 percent of the energy.

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。 House Sitting

In many countries of the world people do what is called house sitting. It means that if owners of the house are going away, they want someone to come into their home and look after the house and maybe pets while they are away.

In Australia, many people travel. After people retire, they might buy a van and travel all over the country. 36.

So if someone wants to travel or go away for some reason, they might want someone in their home to care for it and keep the gardens tidy. House sitters might have to care for pets. Also, quite a few people have swimming pools in their back yard and they need cleaning.37. I feel it is a great way of seeing the country, because you go and stay in a new city, get to meet new people, and have time to go sightseeing in a new area.

38 There are websites where you find the advertisements by people who want to travel, and by replying to the advertisement, you can make arrangements to go and look after their home.

There are some requirements to be a house sitter. You must be a trusted person, so that the home owner knows you will not steal anything. You must be able to go when the house owner wants you to go, so you need lots of free time.39. You need to be good with pets, able to care for cats and dogs, or other pets they may have. Some house sitting jobs are just for a few days or a couple of weeks while the house owners have a short holiday. Sometimes it is for much longer. We have had one house sit for six months, while the home owner travelled to Europe.

40. Then you can travel to many different countries and stay there. One of the important things to get is references from the home owners where you have stayed. A reference is a written letter to say that you are trustworthy and have looked after their home well. You can show these letters to possible house sitting jobs and they know you will do a good job.

A. I have done house sitting many times.
