Excused from recycling(回收利用) because you live in a high rise with a rubbish chute (垃圾道)? You won't be for long. Miami's Mark Shantzis has made it simple for those living in tall buildings to use the chute and recycle too .
In Shantzis' Hi-Rise Recycling System, a chute leads to a pie-shaped container with six boxes that can turn around when operated. The system , which fits in the same space as the chute and container now in use, enables glass , plastic , paper , metal , and other rubbish to go into separate boxes .
The system is controlled from a board next to the chute door. The board has a button for each class of recycling materials (as well as for unrecyclables). At the press of a button, a microcomputer locks all other floors' chute door and sets the recycling container turning until the right box comes under the chute. The computer also counts the loads and gives a signal by phone when the box is full. And a particular piece of equipment breaks up the nonrecyclables
Sorting(分类) recyclables before they are collected saves the use of expensive materials recovery equipment which otherwise has to do the sorting . Such equipment often makes recycled materials very expensive, so expensive that tons of recyclables remain wasted . Shantzis believes his system could help recycled materials become more cost-effective.The purpose in writing this text is _________.

If you happen to find “On the Road” at a gas station or “Who Moved My Cheese?” in your grocery store, it might not be and accident. You could be the unwitting beneficiary of a “bookcrosser”---- a person who on purpose leaves books in public places hoping they’ll be found by strangers.
The idea o leaving a book for someone else to find and enjoy is not new ---- some people have been leaving just-finished books in airports and on buses since the dawn of the hurry-up-and-wait. Creating a system for book-leavers to find out what happened to those books adds a new way to the practice. Bokcrossing.com, the website that encourages books to be “released into the wild”, has more than 18,000 members since its start last year, and averages 112 new participants daily.
Its members have scattered(分发) more than 42,000 novels, self-help books, memoirs, technical manuals and biographies in 45 countries, leaving them in public restrooms, movie theatres, coffee studios or anywhere that they can imagine. The result: a worldwide living library.
Peri Doslu, a California yoga instructor, has dropped three--- one on top of a telephone booth, one on a rock wall at remote Mono Lake in the eastern Sierra Nevada, and another in one of the studios where she teaches.
“I’m always looking for paces to pass on books,” said Doslu. “To think my book’s going to go off and have this future, and I might even get to know a little bit about it down the road.”If you are an unwitting beneficiary of a bookcrosser, that means_____.
| A．you get a book on how to avoid accidents |

However, 42 percent of cell phone owners also said they used the devices “very often” or “sometimes” while driving. Although most agree that the banning is good, only 38 percent believed such a ban would be easy to enforce(实施).

The passport photographs of the future could turn out to be more than just another pretty picture if a new computer technique developed by Israeli scientists catches on.
Researchers at Ben-Gurion University, in Israel, have invented a way to hide information such as a fingerprint or signature in color images. They believe this could improve passport safety or be used to produce product bar codes(条形码) or designs that cannot be seen.
“The papers can be faxed, scanned(扫描) and reprinted without hidden data disappearing,” New Scientist magazine said last week.
Joseph Rosen and a team of scientists worked out the new instrument by creating a mathematical model.
The model turns a fingerprint or signature into a series of numbers which are used to shape the dots that make up a color picture.
“Each dot can be forced out of the usual place slightly without noticeably changing the final appearance of the image,” the magazine said.
Several images that can be hidden in a single picture are scanned into a computer which does the work.
The hidden images or fingerprints cannot be shown until the picture is scanned again.
The computer rebuilds the fingerprint by measuring the displacement of the dots in the picture.
The magazine said that if he model is used for passport checkpoints the picture can be unscrambled(解码) to show the fingerprint or signature and checked against the person holding the passport.
The researchers are now working on a handheld, and instrument which could make unscrambling the hidden information easier. The new passport photos will probably contain all EXCEPT _____.
| A．one’s picture | B．one’s fingerprint |
| C．one’s signature | D．one’s blood type |
The writer probably got the information about the new passport photos from ___.
| A．Israeli scientists | B．a radio or TV | C．a newspaper | D．a magazine |
What is the best title for the passage?
| A．A New Computer Technique by Israeli Scientists |
| B．A New Way t Hide Information |
| C．The New Passport Photo: More Than Meets the Eye |
| D．Safe Passport Photos |
My father had returned from his business visit to London when I came in, rather late, to supper. I could tell at once that he and my mother had been discussing something. In that half-playful, half-serious way I knew so well, he said, "How would you like to go to Eton?"
"You bet," I cried quickly catching the joke. Everyone knew it was the most expensive, the most famous of schools. You had to be entered at birth, if not before. Besides, even at 12 or 13, I understood my father. He disliked any form of showing off. He always knew his proper station in life, which was in the middle of the middle class, our house was medium-sized; he had avoided joining Royal Liverpool Golf Club and went to a smaller one instead; though once he had got a second-hand Rolls-Royce at a remarkably low price, he felt embarrassed driving it, and quickly changed it for an Austin 1100.
This could only be his delightful way of telling me that the whole boarding school idea was to be dropped. Alas! I should also have remembered that he had a liking for being different from everyone else, if it did not conflict(冲突) with his fear of drawing attention to himself.
It seemed that he had happened to be talking to Graham Brown of the London office, a very nice fellow, and Graham had a friend who had just entered his boy at the school, and while he was in that part of the world he thought he might just as well phone them. I remember my eyes stinging(刺痛) and my hands shaking with the puzzlement of my feelings. There was excitement, at the heart of great sadness.
"Oh, he doesn't want to go away," said my mother, "You shouldn't go on like this.” “It's up to him," said my father. "He can make up his own mind."The house the writer's family lived in was ________.
| A．the best they could afford | B．right for their social position |

| A．it drew attention to him | B．it didn't bring him in arguments |
| C．it was understood as a joke | D．there was no danger of his showing off |
What was the writer's reaction to the idea of going to Eton?
| A．He was very unhappy. | B．He didn't believe it. |
| C．He was delighted. | D．He had mixed feelings. |
