举一反三
We all stood at the far end of the studio as workmen prepared the scene, setting up trees at the edge of a winding path. Very soon, bright lights were turned on and the big movie-camera was wheeled into position. The director shouted something to the camera operator and then went to speak to the two famous actors nearby. Since it was hot in the studio, it came as a surprise to us to see one of the actors put on a heavy overcoat and start walking along the path. A big fan began blowing tiny white feathers down on him, and soon the trees were covered in “snow". Two more fans were turned on, and a "strong wind" blew through the trees. The picture looked so real that it made us feel cold.
The next scene was a complete contrast (对比). The way it was filmed was quite unusual. Pictures in front taken on an island in the Pacific were shown on a glass screen (幕). An actor and actress stood of the scene so that they looked as if they were at the water’s edge on an island. By a simple trick like this, palm trees(棕榈树), sandy beaches, and blue, clear skies had been brought into the studio!
Since it was our turn next, we were left wondering what scene would be prepared for us. For a full three minutes in our lives we would be experiencing the excitement of being film "stars"!

The purpose and cause of yawning are still a mystery. Scientists are not sure what causes a yawn. People yawn when they are tired or bored, but they also yawn when they aren’t. There are many ideas explaining why we yawn.
One idea is that yawning is a way for the body to become more alert by taking in more oxygen. A yawn increases the heart rate, forces carbon dioxide out of the lungs and blood stream, and brings oxygen to the brain. But one study showed that volunteers given a lot of oxygen did not yawn any less than before, while those given a lot of carbon dioxide did not yawn more.
Another idea is that early humans used yawning as a form of communication. If one decided it was time to sleep, they would tell the others by yawning and they would do it in return to show they agreed.
A third explanation comes from psychology professor Gordon Gallup of University at Albany in New York. He said that as people yawn, they cool off their brains. “Brains are like computers.” he said. “They only operate efficiently and effectively when they’re cool. Many things connected to yawning, like being tired, make the brain hot, and yawning can reduce the heat.”
Scientists have sent people into space, and created terrible nuclear weapons, but there are lots of seemingly simple things, such as why we yawn, or hiccup（打嗝）, that they can’t figure out. Next time you are in class in the morning, let out a big yawn and watch to see how many of your classmates yawn in response!
小题1:What’s the purpose of the description of how bad you may feel when you’re woken up in the morning?
| A．To explain why humans yawn. |
| B．To explain how humans start yawning. |
| C．To lead into the topic of yawning. |
| D．To complain about being woken up by the clock. |
| A．A way to show that you feel hot. |
| B．A way to get rid of carbon dioxide. |
| C．A way to cool off your brain. |
| D．A way to communicate. |
| A．When you feel frustrated. |
| B．The weather is hot. |
| C．Someone else yawns near you. |
| D．When you breathe in a lot of carbon dioxide. |
| A．The real reason why humans and most animals yawn. |
| B．Hiccups are an involuntary human action similar to yawns. |
| C．The more an action can be studied, the easier it is to research. |
| D．Finding out why humans yawn should be easier than sending people into space. |
In videos of the experiment, he can see the children kicking, hiding their eyes--trying to exercise self-control so they can wait and get two candies．The results are different．Some broke down and rang the bell within a minute．Others lasted 15 minutes.
The children who waited longer went on to get higher SAT scores．They got into better colleges and had better adult success．The children who rang the bell quickest were more likely to have received worse teacher and parental evaluations （评价） 10 years later and were more likely to have drug problems at age 32.
The experiments are worth noting because people spend a lot of time thinking about how to improve education, how to become rich．But when the result is not good, they will come back to ask "how do we get people to get the sort of self-control that leads to success?" This is to enter the world of human nature.
So these experiments along with everyday experience, tell us that self-control is most important．Young people who can sit through sometimes boring classes to get a degree can work hard in order to learn a language well．They can avoid drugs and alcohol．For people without self-control skills, however, school is a series of failed ordeals（煎熬）．No wonder they drop out and their later life is a group of foolish ideas, such as drug use, stealing and so on.

It’s 3:30, and pupils at Raynham Primary School in London are gathering for their after-school maths lessons.
Five time zones— thousands of kilometers away—their math tutors are also arriving for class. High-speed Internet has made it possible for Indian tutors to teach British pupils in real time. Each pupil gets a dedicated one-to-one online tutor. The students work with activities on their computer screen and wear a headset and microphone to talk to their tutor.
The class teacher, Altus Basson, says he has seen an improvement in results. “There are some children who’ve really rocketed in their results. Children who struggleto focus in class focus a lot better on the laptops. The real advantage is that each child gets a focused activity and a single tutor,” he said.
Such individualized teaching is the core idea of Brightspark Education, the company that provides the online tutoring, says founder Tom Hooper. “Children today feel very confident online; they feel very engaged; they feel very in control. And that"s half the battle with education.Give them control, make them feel confident and enjoy their learning and you"ll see them start to improve and embrace it," he said.
Raynham Primary School is among the first in Europe to try online tutoring. At between $20 and $25 an hour, it"s about half the cost of face-to-face coaching. But some people say an Internet connection is not enough of a connection for teaching and learning. Kevin Courtney is deputy General Secretary of Britain"s National Union of Teachers. "We think, there"s a really important emotional connection between a teacher and a child whether it"s a whole class or whether it"s one-to-one. You need that immediacy of feedback and we"re not convinced that that can happen across an Internet connection. In one of the wealthiest.countries in the world, we think that we can afford to have teachers with genuine emotional connection there with the children," he said.
Brightspark Education says the online tutoring is used only as an addition to supplement regular teaching. The company says its service does not represent a threat to teachers" jobs in Britain.
Parents say they"re very satisfied with the results they"ve seen. And what about the children?Children: "I love it!"I love it!"I hate maths!" So math--or, as the British call it, maths—is still not everyone"s favorite subject even with the latest technology to teach it.
小题1:What do we know about the online tutoring?
| A．Indian tutors are helping to teach math in Britain. |
| B．Tutors and students are in different places. |
| C．An online tutor helps several students at the same time. |
| D．Tutors and students communicate by telephone. |
| A．It shows a threat to teachers’ jobs in Britain. |
| B．It can take place of the regular teaching. |
| C．It only pays attention to math teaching. |
| D．It emphasizes the individualized teaching. |
| A．online tutoring will represent a threat to teachers’ jobs in Britain |
| B．online tutoring has a great influence on British. |
| C．the emotional connection between a teacher and a child is important |
| D．immediacy of feedback can happen across an Internet connection |
| A．A New Teaching Pattern |
| B．Indian Teachers and British Students |
| C．To Learn Maths with the Latest Technology |
| D．Indian Tutors Teach British Kids Online |
Very soon, unimaginably powerful technologies will remake our lives．This could have dangerous consequences, especially because we may not even understand the basic science underlyi ng them．There’s a growing gap between our technological capability and our basic scientific understanding．We can do very clever things with the technology of the future without necessarily understanding some of the science underneath, and that is very dangerous．
The technologies that are particularly dangerous over the next hundred years are nanotechnology （纳米技术）, artificial intelligence and biotechnology．The benefits that they will bring are beyond doubt．But they are going to be very, very dangerous．I’m working in the field of artificial intelligence．I have a model design for something that might be 50,000 million times smarter than the human brain．Target date is 2010．The only thing that"s not possible in the film Terminator（终结者） is that the people win．If you"re fighting against technology w hich is 50,000 million times smarter than you, you probably will not win．
Nanotechnology．We"ve all heard of the grey glue problem, that self-replicating nanotech devices might keep on copying until the world has become sticky glue．And certainly in biotechnology, we"ve really got a big problem because it"s converging with nanotechnology and IT．Once you start mixing nanotech with organisms and you start feeding nanotech-enabled bacteria, we can really go an awful lot further than the Borg in Star Trek（星际迷航）．And those superhuman organisms might not like us very much．
Eventually these technologies will become routine．That’s a threat to humanity．I don’t think it’s possible to slow it down．So what we need to do is accelerate the scientific research and try to get some extra tools．The problems facing us in the future are getting bigger and bigger．I think if we don’t get some proper science done, the future is hopeless indeed．
小题1:From the text, we know that the author’s greatest concern is ．
| A．our lack of technological understanding of the process involved |
| B．our lack of technological capability |
| C．creating technology without really understanding the basic science |
| D．Our refusal to face the consequences of the technology we create |
| A．thinks people overvalue the capabilities of technology |
| B．is not optimistic that artificial intelligence will always be used positively |
| C．thinks that we should take science fiction movies more seriously |
| D．believes artificial intelligence is the greatest threat we face technologically |
| A．Because the power of the technology is exaggerated（夸大）． |
| B．Because the strength of the machines is much greater． |
| C．Because machines with that much intelligence can easily defeat humans． |
| D．Because human beings are not courageous enough to win the battle． |
