Windows 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 turn of a switch.

“It took us a long time to figure out what a window really is,” says Claes Granqvist, 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 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 some technologies involving changes of color.

Electrochromic windows use electricity to change color. For example, a sheet of glass coated with thin layers(层) of tungsten oxide(氧化钨) 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(电压) 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 shock of voltage to turn the window from one state to the other. Then, it stays that way. Transitions take 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.”

67.Which statement 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.

68.According to the passage, smart windows are windows_______.

A.that are coated                        B.that use electricity

C.the color of which can be changed        D.that have many layers

69.To make electrochromic windows change color, what is applied to the window glass?

A.Electricity.     B.Tungsten oxide.    C.A battery.         D.A voltage.

70.What will be the benefit if the research on smart windows turns out to be successful?

A.The buildings will look different.

B.Windows can be as large as you want.

C.We may not need air conditioners any more.

D.They are less expensive than traditional windows.

Now that you’re already in the workforce, you know what works for you. This knowledge can not only help you find a good job. 1.

The golden rule is to keep your job hunt separate from your current work. Don’t look for jobs while you’re working, and never use a work computer to search job listings. 2.

Great a networking tool as social media is, NEVER post that you’re looking for a job on Facebook or any other social media accounts. 4. You don’t want to start any rumors（传言）that you’re searching for a job, and you definitely don’t want anyone, especially your boss, to find out from someone else, especially from your social media account.

5. It presents an opportunity for you and your boss to have a frank discussion about what could make the job a better fit for you. Maybe you’ll end up getting the advancement or salary increase or other career path that would make you want to stay.

Comera is the only place in the world which has a whistle(口哨)language. We do not know how and why it began because we do not know the complete history of the island. But we can certainly imagine the reasons for the beginning of the whistle language. There are many deep valleys on the island. A person on one side of valley cannot easily shout to a person on the other side. But he can whistle and be heard from four miles away, and the record is seven miles. The people who live on the island usually have good teeth, and this helps them to whistle well. They must also have good ears so that they can hear other whistlers.

We can understand why the whistle language continues. It is very useful on the island, and quite easy to learn. When somebody is hurt or ill, the whistle language takes the place of the telephone. If the sick person is a long way from the town, boys and men pass the news from one to another. A boy guarding cattle on a hillside whistles to a man fishing from his boat. The last one is able to describe the trouble fully and exactly to the doctor in town. People help each other in the same way when a car breaks or a cow is lost.

The whistle language is hundreds of years old, and probably it will continue to live for hundreds of years more. Radio and TV often kill the special ways of speaking in the different parts of a country. But on Comera island you are nobody if you cannot whistle. Perhaps soon after TV arrives on the island, the people there will be whistling the news and other facts and opinions.

1.If a person on Comera island is ill, 　　.

A. others will phone the doctor in town

2. From the passage we know radio and TV　　at that time.

A. killed the special ways of speaking

B. whistled all the news and opinions

3. Comera island is special in that　　.

A. it attracts visitors every year

B. no visitors have ever been there

C. people there have special ears to hear whistles

D. people there use the whistle language to communicate with each other

4. Which of the following is NOT true according to the passage?

A. It is not easy for a person to live on Comera island if he cannot whistle.

B. The whistle language can only be found on Comera island.

C. The whistle language has been used for hundreds of years on the island, but will not be used any longer.

D. The record shows that one best whistler can be heard by others seven miles away.
