题目列表(包括答案和解析)

B

From E-mail to online shopping, you may think you’ve heard everything there to know about the electronic frontier (新领域).But with hundreds of thousands of Web pages being added weekly, there are plenty of surprises out there.Here are some of the most intriguing (有迷惑力的).

……

Put your kid on a greeting card.Here is how: simply take some pictures with a regular camera, and then ask the photo service to develop them digitally (数字化).For a small fee, you’ll receive your photos on a desk.Put that into your computer and, with a few clicks of the mouse, you can view your photos on the screen.With a few more keystrokes, you can attach the photos to email and send them to friends and relatives worldwide.

  Sign on to one or several greeting card’s Websites (http://www.cardcentral.net/ is an index of more than 1200 electronic card sites) and create an electronic birthday or holiday card.Using your digital photos, you can paste your grandchildren onto the cover.

  If you don’t want to use your own photos, go to cards.amzon.com to browse (浏览) hundreds of images in over 30 categories…all of which you can attach to an electronic greeting card for free.For a nominal fee(很低的费用)you can choose from a library of 75,000 images at http://www.phontodisc.com/.

  Call Australia for free.To have a telephone conversation over the Internet, the person you want to talk to no longer needs a computer.Now all you need to talk to someone in Sydney is one computer with speakers, a microphone, a sound card and some software (available at http://www.vocaltec.com/ or Mricrosoft.com).Typically, you’ll pay a monthly fee (usually under $20) to a service provider, but after that, the calls themselves are local.Sound quality is the same as that of a cell phone.

  Even if you don’t have a computer, you can still use the Web to reduce your long distance phone costs.Some companies offer a service that lets you use an ordinary phone to call another ordinary phone, but charge only a few cents per minute for US calls, because they send them through the Internet.

  Today 48 percent of American homes have computers…a figure that is expected to climb to 60 percent by 2003.And by the end of the next decade, Americans will likely be spending more time shopping, banking, investing and learning on the Internet than in the real world.If you can’t do or find something on the Net today, you probably can tomorrow.

60.Over the Internet, you ________.

       A.can hear everything there

       B.will meet with plenty of surprises which come out every week.

       C.will hear the things about the electronic frontier

       D.can find some things are very interesting

61.From the passage we can infer that _________.

       A.fewer people will use the Internet in the following ten years

       B.more people will study in the regular school by the end of the next decade

       C.fewer people will go to the regular school in the following ten years

       D.more money will be needed for a long-distance call by the end of the next decade

62.If you want to attach to photo to your e-mail, you have to ________ it.

       A.digitalize    B.take       C.picture          D.send

63.Which of the following is NOT true?

A black hole is created when a large star burns out. Like our sun, stars are unbelievably hot furnaces (熔炉) that burn their own matter as fuel. When most of the fuel is used up, the star begins to die.

The death of a star is not a quiet event. First there is a huge explosion. As its outer layer is blasted off into space, the dying star shines as brightly as a billion suns.

After the explosion gravity pulls in what’s left of the star. As the outside of the star sinks toward the center, the star gets smaller and smaller. The material the star is made of becomes tightly packed together. A star is so dense that a teaspoon of matter from it weighs billion of pounds.

The more the star shrinks, the stronger the gravity inside it becomes. Soon the star is very tiny, and the gravity pulling it in is unbelievably strong. In fact, the gravity is so strong that it even pulls light into the star! Since all the light is pulled in, none can go out. The star becomes black when there is no light. Then a black hole is born!

That’s what we know about black holes. What we don’t know is this: What happens inside a black hole after the star has been squeezed into a tiny ball? Does it keep getting smaller and smaller forever? Such a possibility is hard to imagine.

But if the black hole doesn’t keep shrinking, what happens to it? Some scientists think black holes are like doorways to another world. They say that as the star disappears from our universe, it goes into another universe. In other words a black hole in our universe could turn into a “white hole” in a different universe. As the black hole swallows light, the white hole shines brightly—somewhere else. But where? A different place, perhaps, or a different time — many years in the past or future.

Could you travel through a black hole? Right now, no. Nothing we know of could go into a black hole without being crushed. So far the time being, black hole must remain a mystery.

Black holes are a mystery—but that hasn’t stopped scientists from dreaming about them. One scientist suggested that in the future we might make use of the power of black holes. They would supply all of Earth’s energy needs, with plenty to spare. Another scientist wondered if a black hole could some day be used to swallow earthly waste—a sort of huge waste disposal(处理) in the sky!

When the star begins to die ______.

A. there is no fuel left in it                                B. its outer layer goes into space first

C. a huge explosion will happen                         D. it doesn’t give off light any longer

Which of the following doesn’t help produce a black hole?

A. The gravity inside the star is very strong.        B. The light can’t go out of the star.

C. The star becomes smaller and smaller             D. The dying star shines very brightly.

The black hole ______.

A. continues becoming smaller and smaller all the time

B. goes into another universe and becomes a white hole

C. can pull in everything we know of in the world

D. will appear at another place at a different time

What’s the best title for this passage?

A. A New Scientific Discovery: Black Holes

B. How Do Black Holes Come Into Being?

C. What Are Black Holes?

D. Travel Through A Black Hole

    A famous foreign company that invested in China wanted to employ a reception secretary for its public relation department.

    A beautiful girl with a master degree in electric engineering became a winning candidate(候选人) through the difficult process of employment. At its last stage she faced an oral test together with another girl who was her equal not only in good looks but also in education standard. The girl we talk about was confident in herself and successful in the oral test. It seemed that she would get the chance. The examiner told her on behalf of the company that she could come to office of company next Monday as a new employee. At last he asked her, “Have you anything else to say?

“A lot of learning comes through play,” says Mardy McGarry, 52, who has been a special education teacher for 28 years. But her students were too often left out. She had seen the wood chips and sand of traditional playgrounds stop wheelchairs dead in their tracks. When she wanted to build a playground for children with special needs,she knew it wouldn’t take long to develop interest in it around the small fishing village. But she never expected that 2,800 people — a third of the town—would all be willing to make a great effort to bring her vision to life.

McGarry started doing some research into play equipment and contacting design companies and she also found a piece of land available. When the city council(市议会) agreed to set aside an area for a playground, she also asked physical and professional therapists(治疗专家) for their investment. And she turned to her friend, Sue, for help. “Neither of us is good at maths, which is why $450,000 didn’t sound like a lot of money,” McGarry says of the initial estimate.

Her Kiwanis Club came through with $7,000,and that’s when the grassroots movement really got started. One woman gave $25,000 and had her company match it. Soon, smaller businesses were joining in. There was a silent effort to collect money. The local Pieper Family Foundation offered to donate half of the remaining $170,000. All McGarry needed was 500 volunteers to work six 12-hour days.

On September 16, 2008, the first day of construction, they came. Two women heard about the project on the way to work and took the day off to help. A couple in their 80s operated their tractors. Ten-year-olds cleared up the mess. “None of them was paid. It was truly an amazing week,” says McGarry. Only three building managers were paid. Volunteers with “building experience” became coordinators(协调人); those who could operate power tools formed a separate group. One team served meals donated from local restaurants and churches, and another organized activities for the children of volunteers.

Today, Possibility Playground is one of the most popular destinations in Ozaukee County. All children, including the ones with special needs, play shoulder to shoulder. “Some playgrounds have special equipment in a different section. Here, you see all the kids in the same playground, all having fun.”

It’s exactly what McGarry imagined. “People used to ask, ‘Why do you want to build a playground just for children with disabilities?” She says, “It’s only when you build a playground for children with disabilities that you build one for all children.”

It didn’t occur to Mardy McGarry that __________.

A. her plan would soon draw the interest of people in the small village

B. so many people would volunteer to help her realize her dream

C. she would meet with so many difficulties in raising funds

D. the playground would be the most popular destination in Ozaukee County

We can learn from the fourth paragraph that __________.

A. the playground was finished in September 2008

B. everything was well prepared, apart from the volunteers

C. everyone worked unpaid, except for three building managers

D. the playground is so popular that it is overcrowded all the time

It can be inferred from the text that __________.

A. Mardy McGarry is a famous architect in the small town

B. Sue was forced to join in the project because of her son

C. people always ignore the real needs of disabled children

D. Mardy McGarry’s vision has been successfully accomplished at last

What would be the best title for this text?

A. Mardy McGarry: A Woman with Great Determination.

B. Cooperation: The Greatest Power in Overcoming Any Difficulty.

C. Show Real Concern for Poor Disabled Children.

D. Make it Matter to Build a Playground for Disabled Children.
