[1] Look at the center circles of Diagram A and Diagram B. Which of the centre circles looks larger?

[2] Take a first look and you probably think that the centre circle in Diagram A is smaller than that in Diagram B. In fact, they are exactly the same size.

[3]Then look at the picture on the right. What do you see? A vase? Or two faces? Does the picture change quickly from one to the other again and again? Maybe or maybe not, but you can see them at the same time.

[4]“What’s happening? Is something wrong with my eyes?” You may wonder at what you see. Don’t worry. Here is how it goes:

[5]When we look at things, our eyes send messages to our brains and then our brains interpret the information. However, sometimes our brains interpret the received information in a wrong way. It seems that our eyes are playing a joke on us. This often happens and we call it “Visual illusion(幻覺(jué))”.

[6] Movie makers often make use of illusions. They make the objects around actors much smaller or bigger than usual. This makes us believe that the actors are much larger or smaller than they usually are. The movies Jurassic Park and Honey J shrunk the kids just make use of illusions.

C
We have met the enemy, and he is ours. We bought him at a pet shop. When monkey-pox, a disease usually found in the African rain forest, suddenly turns up in children in the American Midwest, it’s hard not to wonder if the disease that comes from foreign animals is homing in on human beings. “Most of the infections (感染) we think of as human infections started in other animals,” says Stephen Morse, director of the Center for Public Health Preparedness at Columbia University.
It’s not just that we’re going to where the animals are; we’re also bringing them closer to us. Popular foreign pets have brought a whole new disease to this country. A strange illness killed Isaksen’s pets, and she now thinks that keeping foreign pets is a bad idea. “I don’t think it’s fair to have them as pets when we have such a limited knowledge of them,” says Isaksen.
“Laws allowing these animals to be brought in from deep forest areas without stricter control need changing,” says Peter Schantz. Monkey-pox may be the wake-up call. Researchers believe infected animals may infect their owners. We know very little about these new diseases. A new bug (病毒) may be kind at first. But it may develop into something harmful. Monkey-pox doesn’t look a major infectious disease. But it is not impossible to pass the disease from person to person.
60. We learn from Paragraph 1 that the pet sold at the shop may _________.
A. come from Columbia            B. prevent us from being infected
C. enjoy being with children        D. suffer from monkey-pox
61. Why did Isaksen advise people not to have foreign pets?
A. They attack human beings.              B. We need to study native animals.
C. They can’t live out of the rain forest.      D. We do not know much about them yet.
62. What does the phrase “the wake-up call” in Paragraph 3 most probably mean?
A. a new disease                     B. a clear warning
C. a dangerous animal                D. a morning call
63. The text suggests that in the future we _______.
A. may have to fight against more new diseases
B. may easily get infected by diseases from dogs
C. should not be allowed to have pets
D. should stop buying pets from Africa

Most people know precious gemstones (寶石) by their appearances. An emerald flashes deep green, a ruby seems to hold a red fire inside, and a diamond shines like a star. It’s more difficult to tell where the gem was mined, since a diamond from Australia or Arkansas may appear the same to one from the Democratic Republic of the Congo. However, recently, a team of scientists has found a way to identify a gemstone’s origin.

Beneath the surface of a gemstone, on the tiny level of atoms and molecules(分子), lie clues (線索) to its origin. At this year’s meeting of the Geological Society of America in Minneapolis, Catherine McManus reported on a technique that uses lasers (激光) to clarify these clues and identify a stone’s homeland. McManus directs scientific research at Materialytics, in Killeen, Texas. The company is developing the technique. “With enough data, we could identify which country, which mining place, even the individual mine a gemstone comes from,” McManus told Science News.

Some gemstones, including many diamonds, come from war-torn countries. Sales of those “blood minerals” may encourage violent civil wars where innocent people are injured or killed. In an effort to reduce the trade in blood minerals, the U.S. government passed law in July 2010 that requires companies that sell gemstones to determine the origins of their stones.

To figure out where gemstones come from, McManus and her team focus a powerful laser on a small sample of the gemstone. The technique is called laser-induced breakdown spectroscopy. Just as heat can turn ice into water or water into steam, energy from the laser changes the state of matter of the stone. The laser changes a miniscule part of the gemstone into plasma, a gas state of matter in which tiny particles(微粒)called electrons separate from atoms.

The plasma, which is superhot, produces a light pattern. (The science of analyzing this kind of light pattern is called spectroscopy.) Different elements(元素)produce different patterns, but McManus and her team say that gemstones from the same area produce similar patterns. Materialytics has already collected patterns from thousands of gemstones, including more than 200 from diamonds. They can compare the light pattern from an unknown gemstone to patterns they do know and look for a match. The light pattern acts like a signature, telling the researchers the origin of the gemstone.

In a small test, the laser technique correctly identified the origins of 95 out of every 100 diamonds. For gemstones like emeralds and rubies, the technique proved successful for 98 out of every 100 stones. The scientists need to collect and analyze more samples, including those from war-torn countries, before the tool is ready for commercial use.

Scientists like Barbara Dutrow, a mineralogist from Louisiana State University in Baton Rouge, find the technique exciting. “This is a basic new tool that could provide a better fingerprint of a material from a particular locality,” she told Science News.

A. an emerald and a ruby are names of diamonds.

B. it’s not difficult to tell where the gem was mined.

C. appearances help to identify the origin of gemstones.?

3.Which of the following facts most probably helps McManus and her team in identifying the origin of stones?

A. Heat can turn ice into water or water into steam.

B. Gemstones from the same area produce similar light patterns.

C. Laser can changes a miniscule part of the gemstone into plasma.

D. Materialytics has already collected patterns from thousands of gemstones.

4.From the last two paragraphs, what can be inferred about the laser technique?

A. It is ready for commercial use.

B. People can use the new tool to find more gemstones.

C. It can significantly reduce the gemstones trade in blood minerals.

D. It will bring about a revolutionary change in identifying the origin of minerals.

Have you ever heard the saying “If you want a friend, be one”?

Here is how a new teacher made friends with the girls and boys in her class on the first day of school. As the bell rang, the teacher smiled at each girl and boy. Then she said in a quiet voice, “Good morning. How nice it is to have all of you in my class this year. I'd like to know each of you. I am sure we will enjoy working together.” Everyone felt that she meant what she said because of her sweet voice and her friendly look.

She told the girls and boys her name and wrote it on the blackboard. Then she told them some of the things she liked to do and she was hoping to do with them during the year.

Then she said to the class, “Now you know my name and the things I like and I want to know your names and the things you like. Then I will feel that I know you.”

When he was just 19, Michael Dell started the company that would dominate the industry.

At the time, IBM personal computers sold in stores for about $3,000. After taking them apart and rebuilding them, Dell realized the components (零部件) could be bought for one-fourth the price. Soon he was buying components to reduce the cost. A good business decision, but it meant his room was starting to look like a mechanic’s shop.

“I was quite excited about the possibilities for personal computers and how they could change society. I had this idea to sell the products directly to the users over the phone”, he said. College plans and his parents’ expectations bothered him a lot. But Michael Dell was determined. He drove off to the University of Texas at Austin in August 1983 in a car he’d bought with earnings from selling newspapers. He was surprised that his mother wasn’t suspicious about the three computers in the backseat. By November, news reached his parents that he wasn’t attending classes. On a surprise visit to Austin, they caught their son on spot. Michael Dell told his dad that he wanted to compete with IBM.

Although Michael agreed to focus on his studies, the business chances and the timing couldn’t have been better. The public was becoming more interested in computers, but no one was producing them. In early May, a week before his final exams, Michael started Dell computer Corporation with $1,000. He took his exams, and then dropped out of college at the end of his freshman year. It was time to try out his direct-to-customer business model.

“Three years later”, Dell says, “we had already achieved annual sales of about $150 million, I was 22 years old then.”

1.What does the underlined word in paragraph 1 mean?

A. affect                      B. develop                            C. support                            D. lead

2.Which of the following is true according to paragraph 2?

A. Dell discovered a good chance to make money

B. Dell could buy a computer at one-fourth the price

C. IBM made little money from personal computers

D. Dell rebuilt computers in a mechanic’s shop

3.When Dell’s parents learned about his absence from class, they       .

A. tried to help with his business                         

B. were too suspicious to accept it

C. wanted him to go hack to class                        

D. encouraged him to compete with IBM

4.It can be inferred from the article that       .

A. Dell was tired of his college life                       

B. Dell was not devoted to his study at college

C. Dell’s college life helped him greatly     

D. Dell didn’t finish his final exams
