We’d been flying for hours, deeper and deeper into the desert of southeastern Niger. The mission: to find what is probably the last wild population of the great Saharan antelope called the addax (旋角羚)—the most endangered animal of its size in Africa.
Pilot Peter Ragg flew our bright red helicopter low over two parallel dunes (沙丘). The pale sand below us was dotted by the black bushes, the plants that are favorite food for the addax. Then, almost as if the dune extruded (使突出) them, two perfect addaxes appeared. Their long tails swung from side to side as they ran, heads held high on thick necks, horns reaching for the sky. We made a few turns in the plane, then let them be. In just a few seconds they were swallowed again by the Sahara. Soon they could just as easily disappear from the planet.
In September 2004 the government of Niger and a small NGO called SOS Faune du Niger surveyed this last known pocket of wild addaxes. They counted 128 individuals. Since then, the number has dropped as hunters have taken more for meat. How many addaxes remain in the Sahara is anybody’s guess, but those that do survive could be considered the living dead: There may not be a viable (能生存的) population left to reproduce.
I’m now helping to make an emergency plan for the last wild addaxes. With a few hundred thousand dollars, some trucks, and a strong group with the local Toubou guides, we may just be able to save these guys from extinction.

In life, people come across many experiences, which they remember throughout their lives. I had a similar experience, too.
I was very excited. It was the day of my last paper of the final examination. My mind was full of thoughts of how I would spend my vacation. I was especially excited of the invitation that my uncle had given me to stay with him for a few days in Cambridge.
I was prepared for the subject, physics. My friends and I were on the ground doing the last minute revisions and also discussing the questions that were supposed to come in the paper. Suddenly the bell rang and we got into our classrooms. The teacher came and quickly handed out the answer paper and the question paper. The paper was of two hours and some of the expected questions came. I finished it almost forty-five minutes earlier. But since it was a rule not to collect the answer paper before the allotted(规定的)time. the teacher was not collecting and I had to sit till the time was over. I checked my paper twice and corrected some of the mistakes in it. I started thinking about the place my friends and I had planned to go after the paper.
Though I was thinking for a long time, the time seemed to be endless. So I thought of drawing something on the question paper and turned it overleaf. I was shocked to see that the page which I had supposed to be blank had four more questions on it which carried 20 marks and would take at least half an hour to complete. I had a quick glance at my watch. There were only 10 minutes left. I was so nervous that I was hardly in a state to write anything. They were the sub-questions(小题)of the last question. Suddenly our physics teacher came in and told all of us that in the last question, out of 6 sub-questions only 2 had to be solved. I felt very much relieved.
Thereafter I never made such mistakes again. But I realized that my anxiousness and excitement could have cost me to lose 20 marks and decided never to make such a mistake again.Which of the following statements is true?

People know the dangers of fires. It’s good for a family to learn how to prepare for a fire. Here are some suggestions.

Buy fire extinguishers(灭火器) in the house. Everyone in the family should know how to use them.
Practice for a fire. They do fire practice because they teach children about fire safety. Ever yone in the family should know the following fire rules:
* Don’t open a hot door! The fire can grow more quickly if you open the door.

Years ago, I lived in a building in a large city. The building next door was only a few feet away from mine. There was a woman who lived there, whom I had never met, yet I could see her seated by her window each afternoon, sewing or reading.
After several months had gone by, I began to notice that her window was dirty. Everything was unclear through the dirty window .I would say to myself, “I wonder why that woman doesn’t wash her window .It really looks terrible.”
One bright morning I decided to clean my flat, including washing the window on the inside.
Late in the afternoon when I finished the cleaning, I sat down by the window with a cup of coffee for a rest. What a surprise! Across the way, the woman sitting by her window was clearly visible. Her window was clean!
Then it dawned on me. I had been criticizing(批评) her dirty window, but all the time I was watching hers through my own dirty window.
That was quite an important lesson for me. How often had I looked at and criticized others through the dirty window of my heart, through my own shortcomings?

To what degree can a computer achieve intelligence(智力)? The answer to this question may lie in a newly-developed US computer program called Smarter Child and the Internet.
If you ran into Smarter Child online, you would be surprised at this kid’s huge memory. It can recite many facts. For example, Smarter Child knows every baseball player in every team this season.
He knows every word in the dictionary and the weather in every major city areas across the US. However, if you ask Smarter Child other questions, you get stranger answers. A question about Smarter Child’s age returns, “One year, 11 days, 16 hours, 7 minutes, and 47 seconds!” Asking where he lives gets, “In a clean room in a high-tech building in California.”
Smarter Child uses the vast information on the World Wide Web as his memory bank. To answer questions about spelling, for instance, Smarter Child goes to American Heritage Dictionary online. For the weather, he visits www. intellicast. com.
Some scientists believe that by joining the many systems of the Internet, an artificial being with the combined knowledge of, say, Albert Einstein, Richard Nixon and Britney Spears could be born. However if Smarter Child wants to think and learn on his own like the boy-computer David in the movie A. I., Artificial Intelligence, he must overcome two problems.
The first is that computers find it difficult to read web pages because the files are labeled in different ways. That’s why programmers need to tell Smarter Child where to look for the weather. It would be a much more difficult task to let him find it himself.
Another problem is that while Smarter Child can process(处理) information more exactly and faster than any human, he lacks common sense—a basic grounding of knowledge that is obvious to any young child.From the text we can infer that www. Intellicast. com is a website .
A.which is specially designed to help Smarter Child |
B.where we people can find Smarter Child |
C.where weather forecasts are made |
D.which is about artificial intelligence |
It is probably most difficult for Smarter Child to .
A.tell us how to spell a difficult word |
B.tell us how the American government is run |
C.provide us with a famous poem by Shakespeare |
D.learn how to tell right behaviors from wrong ones. |
Which of the following is TRUE according to the text?
A. Smart Child has his own memory bank big enough for all kinds of information.
B. A. I. Artificial Intelligence is probably the name of a film about a boy-computer.
C. Smart Child can recognize different files and find information needed on his own.
D. We have similar product now which has the knowledge of Einstein, Nixon and Spears.Which of the following is the best title for the passage?
A.A New Web Child | B.Smarter Child |
C.The Future of Internet | D.Intelligence Development |
