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.

How to Care for Your Ears?
Ears not only let us hear, but they also play a role in maintaining our balance, which is vital to our ability to function in daily life. Yet, we ignore them. We can’t even see our ears, except in a mirror. We take for granted what they do for us day in and day out-until we notice something’s wrong, such as when an earache strikes or when we start having to ask people to repeat what they say. 1.
◆ Clean your ear with a washcloth-covered finger only.
Never put anything inside your ear canal, including cotton swabs (药签). 2.
◆ Leave earwax(耳垢) alone.
Wax is your ear’s way of eliminating(消除) anything foreign that gets into the ear canal. 3. If you find you have too much earwax, use a few drops of earwax remover(去除剂) in the canal. After a few minutes, wash the ear with warm water.
◆ Avoid noisy places.
Rock concerts and construction sites are just a few places that frequently have noise levels that can damage hearing. Any place where you have to shout to be heard should be avoided.
◆ 4.
Be careful not to play MP3 too loud, especially if using earphone.
◆Be careful with illness and medications.
Respiratory (呼吸的) illnesses should be treated to avoid their spread to the ears. Certain medications can damage hearing, so follow the directions carefully before taking them.
See your doctor if you suffer from sudden hearing loss or hear noises in your head. 5.
A. Most people don’t need to clean wax out of their ears.
B. In such case, go to see a doctor as soon as possible.
C. These can be symptoms of a serious illness which needs to be treated.
D. This article will show you how to care for your ears.
E. Turn the volume(音量)down
F. Avoid using earphones while listening to MP3.
G. Your ear canal is very narrow, and a swab can damage it.

Lego is considering a brick (积木) rental plan in an attempt to cut down on plastic waste. The Danish toymaker has promised to make all its bricks from sustainable (可持续的) sources by 2030 and is investing significant resources into finding alternatives.
Tim Brooks, vice-president responsible for sustainability, said the company was “totally open” to the idea of a product rental plan but admitted that lost pieces could produce a significant problem. “What are the chances of giving them to an eight-year-old child and getting them all back again?” Mr. Brooks added.
“There is a lot of technical thinking that needs to be done. We are right at beginning of that.” Mr. Brooks said Lego was exploring several ideas with a view to producing the highest value from products while consuming the least amount of resources. He said many would “probably never see the light of day” and there was no current plan to try out a rental plan.
Lego has come under increasing pressure to reduce its carbon footprint among growing international alarm about the impact of plastic waste on the environment. It produces 19 billion pieces per year—36, 000 a minute—that are made entirely of plastic while much of the inside packaging is also plastic.
So far, the only breakthrough has been the development of a line of bricks made from plant-based plastic sourced from sugarcane. The green trees, plants and flowers were first included in Lego sets late last year but make up only 1%-2% of the total amount of plastic elements produced. Henrik Nielson, a production supervisor (主管) in Lego’s factory, said last year: “We need to learn again how to do this.”
Lego reportedly releases around a million tons of carbon dioxide each year, with about 75% coming from raw materials that go into factories. The company has invested more than 100, 000,000 euros and hired 100 people to research non-plastic alternatives. It is aiming to keep all of its packaging out of landfill by 2025.
1.Lego is making great efforts to ________.
A.promote its brick rental plan B.raise its production efficiency
C.explore ways to reduce plastic waste D.develop new products
2.According to Mr. Brooks, Lego’s brick rental plan ________.
A.is well under way B.has a long way to go
C.is totally useless D.goes against Lego’s interest
3.The writer tells of Lego’s stress of reducing plastic waste by means of ________.
A.figures B.examples
C.comparison D.classification
4.What is Lego’s attitude towards developing non-plastic alternatives?
A.Defensive. B.Determined.
C.Disapproving. D.Doubtful.

Tim Brooks, vice-president responsible for sustainability, said the company was "totally open" to the idea of a product rental scheme but acknowledged that lost pieces could cause a significant problem. He said the rental scheme was "possible" but admitted there were some "technical barriers", one of which is the complexity of some Lego kits (配套元件),many of which contain thousands of pieces.
" What are the chances of giving them to an eight-year-old child and getting them all back again?” Mr Brooks added. "There is a lot of technical thinking that needs to be done.
We are right at beginning of that.” Mr Brooks said Lego was exploring several ideas with a view to producing the highest value from products while consuming the least amount of resources. He said many would "probably never see the light of day” and there was no current plan to try a rental scheme.

1.How will Lego cut down on plastic waste?
A.By considering a brick rental scheme.
B.By producing a new kind of toys instead of bricks.
C.By replacing common plastic with a renewable material.
D.By investing large amounts of money into market.
2.What does Tim Brooks expect of the product rental scheme?
A.It'll cause certain serious problems.
B.It'll be of great complexity.
C.It'll require more mature technical skills.
D.It'll involve much more kits of bricks.
3.What does the underlined word “many” in Paragraph 3 refer to?
A.Ideas. B.Values.
C.Products. D.Resources.
4.What can be inferred from the passage?
A.Lego has to explore a new product to earn a profit.
B.A brick rental scheme has been put into mass production.
C.plant-abased plastic is environmentally friendly.
D.Lego is optimistic about the brick rental scheme.
