Mark and his brother Jason both were looking at the shining new computer enviously, Jason was determined not to go against their father’s wishes but Mark was more adventurous than his brother. He loved experimenting and his aim was to become a scientist like his father.
“Dad will be really mad if he finds out you’ve been playing with his new computer.” Jason said, “He told us not to touch it.”
“He won’t find out,” Mark said. “I’ll just have a quick look and shut it down.”
Mark had been scolded before for touching his father’s equipment. But his curiosity was difficult to control and this new computer really puzzled him.
It was a strange-looking machine — one his dad had brought home from the laboratory where he worked. “It’s an experimental model,” his father had explained, “so don’t touch it under any circumstances.” But his father’s warning only served to make Mark more curious. Without any further thought, Mark turned on the power switch. The computer burst into life and seconds later, the screen turned into colors, shifting and changing and then two big white words appeared in the centre of the screen: “SPACE TRANSPORTER.” “Yes!” Mark cried excitedly, “It’s a computer game. I knew it! Dad’s only been pretending to work. He’s really been playing games instead.” A new message appeared on the screen: “ENTER NAMES
VOYAGER 1:…
VOYAGER 2:…”
Mark’s fingers flew across the keyboard as he typed in both of their names.
“INPUT ACCEPTED. START TRANSPORT PROGRAM. AUTO-RETRIEVE INITIATED (自动回收程序已启动).”
The screen turned even brighter and a noise suddenly rose in volume.
“I think we’d better shut it off, Mark,” Jason yelled, reaching for the power switch. He was really frightened.
But his hand never reached the switch. A single beam of dazzling white light burst out of the computer screen, wrapping the boys in its glow(光芒) , until they themselves seemed to be glowing. Then it died down just as suddenly as it had burst into life. And the boys were no longer there. On the screen, the letters changed.

Grown-ups know that people and objects are solid. At the movies, we know that if we reach out to touch Tom Cruise, all we will feel is air. But does a baby have this understanding?
To see whether babies know objects are solid, T. Bower designed a method for projecting an optical illusion（视觉影像）of a hanging ball. His plan was to first give babies a real ball, one they could reach out and touch, and then to show them the illusion. If they knew that objects are solid and they reached out for the illusion and found empty air, they could be expected to show surprise in their faces and movements. All the 16-to 24- week -old babies tested were surprised when they reached for the illusion and found that the ball was not there.
Grown-ups also have a sense of object permanence. We know that if we put a box in a room and lock the door, the box will still be there when we come back. But does a baby realize that a ball that rolls under a chair does not disappear and go to never-never land?
Experiments done by Bower suggest that babies develop a sense of object permanence when they are about 18 weeks old. In his experiments, Bower used a toy train that went behind a screen. When 16-week-old and 22-week-old babies watched the toy train disappear behind the left side of the screen, they looked to the right, expecting it to reappear. If the experimenter took the train off the table and lifted the screen, all the babies seemed surprised not to see the train. This seems to show that all the babies had a sense of object permanence. But the second part of the experiment showed that this was not really the case. The researcher substituted（替换）a ball for the train when it went behind the screen. The 22-week-old babies seemed surprised and looked back to the left side for the train. But the 16-week -old babies did not seem to notice the switch（更换）. Thus, the 16-week-old babies seemed to have a sense of “something permanence,” while the 22-week-old babies had a sense of object permanence related to a particular object.

C. The younger babies liked looking for missing objects.
D. The babies couldn’t tell a ball from its optical illusion.
It's not the flashiest car in the world. Not even close. But the 1971 Volkswagen named Helioscan do something most cars can't: nm on solar energy – energy from the sun's light and heat!
Joshua Bechtold, 14, and the other students at the Riverside School in Lyndonville, Vermont, worked many months to get Helios ready for the 1999 American Tour de Sol （"Sol" is the Latin word for "sun"）. They named their car after Helios, the sun god in Greek mythology（神话）.
The 4-year-old Tour de Sol encourages the use of "green", or environmentally friendly, cars to help reduce pollution and save energy. It’s not a race. Cars are judged on fuel efficiency（耗油量） rather than speed. In the week-long event, 44 cars took the 350-mile tour from Waterbury, Connecticut, to Lake George, New York. Of the 23 student cars, Helios was the only one built by middle school students.
A teacher drove Helios, but the children talked with people wherever they stopped along the mad. "That was my favorite part," says Anna Browne, 15. "We explained how the car runs.”
Due in part to old, inefficient batteries（电池）, Helios finished fourth - out of four - in its kind, the sun-powered class. "We were there for the fun of it," Anna says. "We're proud of Helios," says Ariel Gleicher, 14. "It's a car that's good for the environment."
64. What is special about the car Helios in the text?
A. It was built by middle school students.
B. It has an attractive design.
C. It was made in 1971.
D. It won the fourth prize.
65. How many sun-powered cars took part in the race?
A. 1. B. 4. C. 23. D. 44.
66. What would be the best title for the text.'?
A. The Making of Helios
B. 1999 American Tour de Sol
C. Sun-powered Cars on the Road
D. Use of Green Cars in Connecticut
67. The students felt proud of Helios because______.
A. it could run as far as 350 miles B. it was favored by many children

At one time, computers were expected largely to remove the need for paper copies of documents（文件）because they could be stored electronically. But for all the texts that are written, stored and sent electronically, a lot of them are still ending up on paper.
It is difficult to measure the quantity of paper used as a result of Internet-connected computers, although just about anyone who works in an office can tell you that when e-mail is introduced, the printers start working overtime. “I feel in my bones this revolution is causing more trees to be cut down,” says Ted Smith of the Earth Village Organisation.
Perhaps the best sign of how computer and Internet use pushes up demand for paper comes from the high-tech industry itself, which sees printing as one of its most promising new markets. Several Internet companies have been set up to help small businesses print quality documents from a computer. Earlier this week Hewlett-Packard Co. announced a plan to develop new technologies that will enable people to print even more so they can get a hard copy of a business document, a medical record or just a one-line e-mail, even if they are nowhere near a computer. As the company sees it, the more use of the Internet the greater demand for printers
Does all this mean environmental concerns （环境问题） have been forgotten? Some activists suggest people have been led to believe that a lot of dangers to the environment have gone away. “I guess people believe that the problem is taken care of, because of recycling （回收利用）,”said Kelly Quirke, director of the Rainforest Action Network in San Francisco. Yet Quirke is hopeful that high-tech may also prove helpful. He says printers that print on both sides are growing in popularity. The action group has also found acceptable paper made from materials other than wood, such as agricultural waste.
72. The growing demand for paper in recent years is largely due to ___________.

A. people are concerned about the environment
B. printers in many offices are working overtime
C. small companies need more hard copies
D. they see a growing market for printers

LONDON（Reuters）-Organic fruit, delivered right to the doorstep. That is what Gabriel Gold prefers, and he is willing to pay for it. If this is not possible, the 26-year-old computer technician will spend the extra money at the supermarket to buy organic food.
"Organic produce is always better," Gold said. "The food is free of pesticides（农药）, and you are generally supporting family farms instead of large farms. And more often than not it is locally（本地）grown and seasonal, so it is more tasty. "Gold is one of a growing number of shoppers buying into the organic trend, and supermarkets across Britain are counting on more like him as they grow their organic food business. But how many shoppers really know what they are getting, and why are they willing to pay a higher price for organic produce? Market research shows that Gold and others who buy organic food can generally give clear reasons for their preferences-but their knowledge of organic food is far from complete. For example,small amounts of pesticides can be used on organic products. And about three quarters of organic food in Britain is not local but imported（进口）to meet growing demand. "The demand for organic food is increasing by about one third every year, so it is a very fast-growing market," said Sue Flock, a specialist in this line of business.
60. More and more people in Britain are buying organic food because ____.
A. they are getting richer
B. they can get the food anywhere
C. they consider the food free of pollution
D. they like home-grown fruit
61.Which of the following statements is true to the facts about most organic produce sold in Britain？
A. It grows indoors all year round.
B. It is produced outside Britain.
C. It is grown on family farms.
D. It is produced on large farms.
62.What is the meaning of "the organic trend" as the words are used in the text？
A. growing interest in organic food
B. better quality of organic food
C. rising market for organic food
D. higher prices of organic food
63.What is the best title for this news story？
A. Organic food-healthy, or just for the wealthy？
B. The making of organic food in Britain
C. Organic food-to import or not？
D. Good qualities of organic food
Compassion is a desire within us to help others. With effort, we can translate compassion into actions. An experience last weekend showed me this is true. I work part-time in a supermarket across from a building for the elderly. These old people are out main customers, and it’s not hard to lose patience over their slowness. But last Sunday, one aged gentleman appeared to teach me a valuable lesson. This untidy man walked up to my register（收款机）with a box of biscuits. He said he was out of cash (现金), had just moved into his room, and had nothing in his cupboards. He asked if we could let him have the food on trust. He promised to repay me the next day.
I couldn’t help staring at him. I wondered what kind of person he had been ten or twenty years before, and what he would be like if luck had gone his way. I had a hurt in my heart for this kind of human soul, all alone in the world. I told him that I was sorry, but store rules didn’t allow me to do so. I felt stupid and unkind saying this, but I valued my job.
Just then, another man, standing behind the first, spoke up. If anything, he looked more pitiable. “Change it to me,” was all he said.
What I had been feeling was pity. Pity is soft and safe and easy. Compassion, on the other hand, is caring in action. I thanked the second man but told him that was not allowed either. Then I reached into my pocket and paid for the biscuits myself. I reached into my pocket because these two men had reached into my heart and taught me compassion.
