Six Americans are working on a new highway. But this highway won't have any traffic.It's an "ice highway" to the South Pole.

The team has just finished a second year of work on the 1,020-mile highway. "The road is the greatest single footprint of activity we've seen in the Antarctic (南极洲)," said Alan Hemmings, an Australian environmentalist.

The highway will provide a new way for supplies to be trekked (拉, 搬) across the earth on tractor-pulled sleds (雪橇). This method will use a lot less fuel than an aircraft, the current (当前的) way that scientists and supplies reach the Amundsen-Scott Base, a U.S. research station in the South Pole. The highway will also allow for equipment that is too big for planes to carry to be brought to Antarctica.Even with these benefits, there is one disadvantage—a round trip on the road will be 30 days, compared to a few hours by plane.

Making this 20-foot-wide road isn't easy, and it takes a lot of time. The crew (工作队) has been working on the road for two summers, when it's warmer and easier to work with the ice. It probably won't be completed until 2006.

Crevasses (裂缝), or cracks, in the land often make the construction difficult. Crevasses are kind of like pot holes that form when surface ice is stretched.This can be very dangerous, especially when the crevasses are hidden under a layer (层) of snow and can't be seen.

"Last year it took us three months to go three miles across a crevasse field, full of dangerous, hidden crevasses," said the project's manager, John Wright. Each year, more crevasses appear and they have to be filled with snow and ice so the road is safe for travel. The road will also be lined with green flags so travelers know where the safe surface is.

It will probably take ______ years to complete the ice highway.

       A.2     B.4      C.6      D.8

When it is finished, the highway will not be used for ______.

       A.giving supplies to the research station in the South Pole

       B.taking scientists to the South Pole

       C.taking travelers to a tour of Antarctic

       D.bringing huge equipment to Antarctic

How many miles can be covered at most each day if you take the ice highway to the South

Pole?

       A.30.    B.34.    C.68.    D.88.

Which of the following is true according to the passage?

       A.Other crevasses won’t appear if a crevasse has been filled.

       B.Many new crevasses will form after a crevasse has been filled.

       C.Travelers can drive their sleds on the ice highway freely.

       D.There will be less danger if the crevasses are covered by snow.

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.

Princess Diaries star Anne Hathaway has announced she is engaged(订婚).The actress, 29,confirmed the news after she was photographed wearing a ring while with her boyfriend Adam Shulman in Brooklyn yesterday. Shulman, an actor and jewellery designer, worked with Kwiat Heritage Jewels to create the ring. The pair quietly began dating in November 2008,but weren't pictured together until the following year.
“We hit it off immediately the first time we met each other but it took us a pretty long time to get together," she has said of Shulman. “He thought that I had a boyfriend and I thought that he had a girlfriend, so I thought that I'd better keep my distance because I didn't want to be that girl. She described their union as more mature than her previous experiences, adding, “Being mature doesn't always make for a good story, but it makes for a good life.”
Speaking about the relationship in the September issue(期刊)of U.K.s Marie Claire, she said, “Adam totally ruined my plan. I was really actually looking forward to a little time alone tod then I fell in love like a fool. Her romance with Shulman followed a disastrous relationship with an Italian real estate(地产)developer Raffaello Follieri. She split up with him in 2008 when he was arrested on fraud(欺诈)charges and he was later sentenced to four and a half years in prison.
The actress, whose film credits also include Brokeback Mountain and One Day, will next star in the new The Dark Knight Rises. She plays Selina Kyle, also known as Catwoman.
