Dennis Burdens, who wrote an article, tells us that he once saw a UFO himself. He was having dinner one night with a friend near Tripoli, Libya, and after dinner the two men walked across a yard to his room to look at some papers. Burdens noticed that the moon looked strange that night.
“It wasn’t the moon ”, was the reply.
They watched the light and saw that it was moving. It seemed to be an object rather like a big plate. In some ways it looked like smoke with a light on it, but it wasn’t smoke because it didn’t change its shape. It was moving in a regular way. That is to say, it didn’t go suddenly faster or more slowly, and it didn’t go higher or lower. So the two men decided that there must be men in it.
After that, Burdens said that he felt eyes looking at him. He was being watched in the darkness.
When it was nearer, they noticed that the bottom parts were brighter than the top. The bottom was yellow and the top red. Then the object suddenly turned away and left Libya, moving very fast.
On a later day Burdens talked to other people about it, and he found some who had seen it. They all described it in the same way. Could they all be mistaken?

"The uniform makes us look like a bunch of clones, especially when we are doing morning exercises in the playground, "said Qing, a Senior 2 from a high school in Shanghai. "But we are not exactly the same from the top to the bottom. The boys wear different sport shoes and girls have different decorations ( 装饰品 )in their hair. These are the areas where you can express yourself" said Qing.
Although it might be strange for boys to talk about fashion, they do care about what they wear in school, especially shoes, according to Qing.
"Nike and Adidas basketball shoes, although they are still the must for many of my friends ,are becoming out-of-date,” added. He explained, "Since Liu Xiang ran so fast in Athens, running shoes are becoming popular in this autumn."
"Still in fashion are the various baseball caps and American-style T-shirts with random English words printed on them, "said Qing. "The accuracy ( 准确性 )of the written message isn"t important. Often, the words are misspelt . Sometimes they do not even make sense “ Qing said with a smile.
Besides sports shoes and T-shirts, styles and colours of school bags are another opportunity for students to express their taste in fashion. Some bags are made more eye-catching by decorating them with small hanging dolls. Other fashionable items are the colourful drink contains which are now popular among girls this semester.
As in China, the new semester in the US also brings new fashion trends: shirts printed with Chinese words, necklaces with Hebrew ( 希伯莱 )or Hindi ( 印度的 )characters, and Brazilian jewelry, are all common in schools in Florida, according to Carmen Domingues, a high school student.
小题1:What does "a bunch of clones”( Paragraph 2)mean?
| A．All of the clothes are the same. | B．All of the exercises are the same. |
| C．All of the clothes are different. | D．All of the exercises are different. |
| A．The girls wear different sport shoes. |
| B．All the students wear school uniforms. |
| C．The girls have different decorations in their hair. |
| D．The boys drink water from colourful drinks containers. |
| A．Because the shoes are not eye-catching. |
| B．Because running shoes become more popular. |
| C．Because the shoes have been popular for a long time. |
| D．Because they have changed their opinions for Liu Xiang. |
| A．Necklace with Hebrew or Hindi characters. |
| B．Baseball caps and American-style T-shirts. |

Many of these changes which he has brought about have had unforeseen consequences．Who would have thought that the throwing away of a piece of Canadian waterweed would have caused half the waterways of Britain to be blocked for a decade, or that the provision of pot cacti for lonely settlers’ wives would have led to Eastern Australian being overrun with forests of Prickly Pear? Who would have prophesied that the cutting down of forests on the Adriatic coasts, or in parts of Central Africa, could have reduced the land to a semidesert, with the very soil washed away from the bare rock? Who would have thought that improved communications would have changed history by the spreading of disease-sleeping sickness into East Africa, measles into Oceania, very possibly malaria into ancient Greece?
These are spectacular examples; but examples on a smaller scale are everywhere to be found．We make a nature sanctuary for rare birds, prescribing absolute security for all species; and we may find that some common and hardy kind of bird multiplies beyond measure and ousts the rare kinds in which we were particularly interested．We see, owing to some little change brought about by civilization, the starling spread over the English country-side in hordes．We improve the yielding capacities of our cattle; and find that now they exhaust the pastures which sufficed for less exigent stock．
小题1:The following examples except ________ reflect man altering the balance of nature．
| A．man is covering huge areas with new kinds of plants |
| B．man is facilitating the spread of animals into new regions． |
| C．man is killing some species on a large scale |
| D．man is getting to know the importance of keeping the balance of nature． |
| A．Eastern Australian was overrun with forests． |
| B．Half the waterways of Britain blocked for a decade． |
| C．In parts of central Africa, the land reduced to a semidesert． |
| D．Disease-sleeping has been caused． |
| A．Disease-sleeping sickness． | B．Measles． |
| C．Improved communications． | D．Malaria． |
| A．some common and hardy kind of bird multiplies |
| B．rare kinds multiply |
| C．all bird multiply |
| D．no bird multiply |
| A．that man is deliberately destroying the balance of nature |
| B．that man has foreseen the consequences of altering the balance old nature |
| C．that improved communications have changed history |

Here is a two-way student exchange in action. Fred, nineteen, spent last year in Germany with George’s family. In turn, George’s son Mike spent a year in Fred’s home in America.
Fred, a lively young man, knew little German when he arrived, but after two months’ study, the language began to come to him. The school was completely different from what he had expected — much harder. Students rose respectfully① when the teacher entered the room. They took fourteen subjects instead of the six that are usual in the United States. There were almost no outside activities.
Family life, too, was different. The father’s word was law, and all activities were around the family rather than the individual. Fred found the food too simple at first. Also, he missed having a car.
“Back home, you pick up some friends in a car and go out and have a good time. In Germany, you walk, but you soon learn to like it.”
At the same time, in America, Mike, a friendly German boy, was also forming his idea. “I suppose I should criticize② American schools,” he says. “It is far too easy by our level. But I have to say that I like it very much. In Germany we do nothing but study. Here we take part in many outside activities. I think that maybe your schools are better in training for citizens. There ought to be some middle ground between the two.”
Notes:
① respectfully adv. 尊敬地，谦恭地
② criticize vt. 批评，责备

The $386 million Phoenix Mars is planned to touch down in the Martian arctic in 2008. The stationary probe will use its robotic arm to dig into the icy land and pick up soil samples②to analyze. In 2002, the Mars Odyssey orbiter spotted evidence of ice-rich soil near the arctic surface.
Scientists hope the Phoenix mission will find clues to the geologic history of water on the Red Planet and determine whether microbes③existed in the ice.
Phoenix will be the first mission of the Mars Scout program, a renewed, low-cost effort to study the Red Planet. “The Phoenix mission explores new territory in the northern plains of Mars analogous to the permafrost regions on Earth,” Peter Smith said.
True to its name, Phoenix rose from the ashes of previous④missions. The lander for Phoenix was built to fly as part of the 2001 Mars Surveyor program. But the program broke down after the well-known disappearance of the Mars Polar Lander in 1999. The Polar Lander lost contact during a landing attempt near the planet’s south pole after its rocket engine shut off prematurely, causing the spacecraft to fall about 130 feet to almost certain destruction.
The Phoenix probe had been in storage at a Lockheed Martin clean room in Denver before it was reused for its present mission. It will carry science instruments that were designed for the Mars Surveyor program including an improved panoramic camera and a trench-digging robotic arm. Phoenix will lift off from the Kennedy Space Center in August 2007 and land on the planet nine months later.
Notes:
① clue n. 线索
② sample n. 标本，样品
③ microbe n. 微生物
④ previous adj. 先前的

The deepest oil well enters a mere six miles into the crust (地壳) (the center of the earth is about 4,000 miles deeper). Russian scientists dug the deepest hole in Siberia, but bottomed out at about 7.5 miles below the surface. The Mohole project, a U.S. plan in the 1950s, called for drilling a hole 25 miles down to the boundary between the hard rocks of the crust and the soft mantle (地幔). Sadly the project involved government supporting.
It gets harder and harder to drill deep into the earth because rocks get softer and softer. Hard but easily broken at the surface, rocks become plastic at depth, and the pressure caused by the weight of the overlaying crust --- about 52,800 pounds per square inch at a depth of ten miles, makes further drilling impossible.
What little we know about the inside of the earth (like the fact that there"s a crust, a mantle, and a core) comes from indirect evidence, such as the analysis of earthquakes.
So maybe it"s time for a thorough new method to explore the earth"s inside. Scientist David Stevenson says we should forget about drilling holes. Instead, we should open a crack (裂缝).
Stevenson suggests digging a crack about a half mile long, a yard wide, and a half mile deep (not with a shovel) but with an explosion on the scale of a nuclear bomb. Next, he"d pour a few hundred thousand tons of molten (熔化的) iron into the crack, along with a robot. The iron, thicker than the surrounding crust, would move downward at about 16 feet per second, carrying the robot with it and opening the crack deeper and deeper. The iron mass would drop for about a week and 2,000 miles to the outer edge of the earth core, the robot sending out data to the surface.
Stevenson compares his idea to space exploration. "We"re going somewhere we haven"t been before,"he says. "In all possibility, there will be surprises.”
This idea can probably be put in the drawer marked with Isn"t Going To Happen. The robot would have to survive temperatures that would melt pretty much anything. But Stevenson"s idea may inspire a new look at an old problem. Great things can come from what seems like impossible ideas.
小题1:Going inside the earth is _____ than going into space.
| A．more interesting | B．more possible | C．easier | D．more challenging |
| A．6 miles. | B．4,000 miles. | C．7.5 miles. | D．25 miles. |
| A．It is an inspiring but not practical idea now. |
| B．It is a practical proposal that has come into use now. |
| C．It is a good proposal that will soon be put into practice. |
| D．It is a false theory that cannot be carried out at all. |
| A．An Annoying Problem for Humans |
| B．To the Center of the Earth |
| C．The Mohole Project |
| D．David Stevenson"s Proposal |
