Several dollars equal nothing for some people, but make a difference for others. Steve has just lost his wife to cancer and everything they had is gone due to the treatment. He now lives in the shelter for the homeless. So we know each other.
Just like other homeless people, he didn’t think he needed anything. But once he mentioned to me he needed eye glasses. His voice hesitated a bit, he looked down, and it appeared like he thought such a request was just a dream. Too much to hope for? It was as if his wish were known by me only.
I submitted an application for him to a program that is supposed to provide a free eye examination and glasses. Three months later, I phoned to ask what was up with the appointment but they told me there was a cash flow problem until late summer.
Steve showed disappointment, thanked me and started to walk away. I said, “Hold on, I will figure out a way to get you an eye examination and glasses.” His face lit up a tiny bit. He had seen some of the things I have done for other people in our shelter and to me it looked like he might have a line of hope.
I took a picture of him and posted his picture and his story in the Twitter. In about 4 days, eight people from around the world donated $25 each and one person donated $40 and I made up the rest to get him an eye exam and glasses.
Steve picked up his glasses on Wednesday: May 11th, 2011. Today Steve has returned to a previous job he had in a nearby car wash. Because he now has glasses he will be able to see what he is doing while cleaning the vehicles. He is starting a second job at a pet center next week!We can learn from the first two paragraphs that ______.

Move Earth—it’s no science fiction
LONDON—Scientists have found an unusual way to prevent our planet from overheating: move it to a cooler spot. All you have to do is send a few comets（彗星）in the direction of Earth, and its orbit will be changed. Our world will then be sent spinning into a safer, colder part of the solar system.
This idea for improving our climate comes from a group of US National Aeronautics and Space Administration（NASA） engineers and American astronomers. They say their plan could add another six billion years to the useful lifetime of our planet—effectively doubling its working life.
The plan put forward by Dr Laughlin, and his colleagues Don Korycansky and Fred Adams is designed to carefully direct a comet or asteroid（小行星） so that it passes close by our planet and sends some of its gravitational energy to Earth.
“Earth’s orbital speed would increase as a result and we would move to a higher orbit away from the Sun,” Laughlin said.
Engineers would then direct their comet so that it passed close to Jupiter or Saturn. The comet would pick up energy from one of these giant planets. Later its orbit would bring it back to Earth, and the process would be repeated.
In the short term, the plan provides an ideal way to global warming, although the team was actually concerned with a much greater danger. The sun is certain to heat up in about a billion years and so “seriously compromise” our biosphere（生物圈）by cooking us.
That’s why the group decided to try to save Earth.
The plan has one or two worrying aspects, however. For a start, space engineers would have to be very careful about how they directed their asteroid or comet towards Earth. The smallest miscalculation（误算）in orbit could fire it straight at Earth—with deadly consequences.
There is also the question of the Moon. As the current issue of Scientific American magazine points out, if Earth was pushed out of its current position, it is “most likely the Moon would be stripped(剥去) away from Earth,” it states. This would greatly change our planet’s climate.What makes the scientists plan to move Earth?
| A．A few comets are moving to the direction of Earth. |
| B．Earth’s working life is coming to an end soon. |
| C．Earth will become too hot for mankind to keep alive. |
| D．The moon is moving farther and farther away from Earth. |
If the plan is successful, Earth will have a working life of ______ years.
| A．12 billion | B．6 billion |
| C．18 billion | D．24 billion |
What serious problems might the plan cause according to the passage?
| A．The comet might hit Earth and man might lose the moon. |
| B．Earth might be moved too far away and man might be frozen to death. |
| C．The comet might hit Jupiter or Saturn and never return to Earth. |
| D．Earth’s working life might be greatly shortened. |
What does the underlined word “compromise” mean?
| A．provide | B．benefit |
| C．share | D．Endanger |
Carmen Arace Middle School is situated in the town of Bloomfield，but four years ago it faced many of the same challenges as inner—city schools nearby：low scores in standardized tests and dropping enrollment（入学率）of students．Then the hard-driving headmaster, Delore Bolton，persuaded her school to shake up the place by buying a laptop computer for each student and teacher to use in school and at home．For good measure，the board provided wireless Internet access at school．Total cost :$5 million．
Now an hour before classes start，every seat in the library is taken by students eager to get online．The teacher talks about rocks as students view them at a colorful website，after school students on buses pull laptops from backpacks to get started on homework．Since the computers arrived，scores in state tests are up 35％and the enrollment increases by 20％．
Indeed，school systems in rural areas are eager to follow Carmen Arace Middle School’s example．Angus King，the state governor, has proposed using$50 million from an unexpected budget to supply computers for students．
However, the school is seeking federal grant money to expand the laptop program．In the meantime，most of the problems have been worked out．Some students use computers to visit unauthorized websites，but teachers have the ability to track where students have been and restrict them．“That is the worst when they disable you” says a boy．The habit is rubbing off on parents．“I taught my mom to use e-mail．”says the honorable girl．“And now she is taking computer classes．I’m so proud of her!’’By introducing the laptop program, Delore Bolton has .

In the future your automobile will run on water instead of gas! You will be able to buy a supercomputer that fits in your pocket! You might even drive a flying car!
Not all past predictions have been proven wrong. A few of them have been surprisingly accurate. Some great thinkers predicted the arrival of the credit card, the fax machine and even the internet years before they happened. But for each prediction that has come true, some others have missed by a mile. Many of these predictions didn’t consider how people would want to use the technology, or if people really needed it in their lives or not. Let’s look at some predictions from the not-too-distant past.
Robot Helpers
Where’s the robot in my kitchen? Nowhere, of course. And he’s probably not coming anytime soon. Robots do exist today, but mostly in factories and other working environments.Back in the 1950s, however, people said that by now personal robots would be in most people’s homes.So why hasn’t it happened? Maybe because robots are still too expensive and clumsy. And probably the idea of robots cooking our dinners and washing our clothes is just too strange. At home we seem to be doing fine without them.
Telephones of tomorrow
In 1964 an American company introduced the video telephone. They said by the year 2000 most people would have a video phone in their homes. But of course the idea hasn’t caught on yet. Why? The technology worked fine, but it overlooked something obvious: people desire for privacy. Would you want to have a video phone conversation with someone after you just stepped out of the shower? Probably not--it could be uncomfortable! Just because technology doesn’t always mean people will want to use it.
And finally, how about that crazy prediction of the flying car? It’s not so crazy any more! But a flying car remains one of the most wonderful technology ideas to catch our imagination. Keep watching the news or perhaps the sky outside your window to see what the future will bring..The passage mainly deals with______.
| A．predictions that can catch our imagination |
| B．predictions that haven’t come true |
| C．new technology can benefit our life |
| D．predictions that have come true |
According to the passage, which of the following statements is NOT true?
| A．Technology doesn’t always mean people will want to use it. |
| B．Predictions don’t need to consider people’s practical use of the technology. |
| C．Not all the high-tech things people thought we’d be using by now are widely used |
| D．High-tech things are not always convenient to people’s life. |
Robot Helpers haven’t been used in most people’s homes because______.
| A．using the kind of robots at home is simply a waste of time and money |
| B．the kind of robots hasn’t been developed yet |
| C．people find it difficult to control the kind of robots |
| D．the kind of robots won’t bring people practical use |
How does the writer find the flying car?
| A．It is too difficult to imagine. |
| B．It is too crazy an idea to realize. |
| C．It is likely to appear in the future. |
| D．It has been the focus of the news. |
