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 |

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．

The year is 2094. It has been announced that a comet (彗星) is heading towards the Earth . Most of it will miss our planet , but two pieces will probably hit the southern half of the Earth .
On 17 July , a piece four kilometers wide enters the Earth’s atmosphere (大气层) with a massive explosion . About half of the piece is destroyed , but the remaining part hits the South Atlantic at 200 times the speed of sound . The sea boils and a huge hole is made in the sea bed . Huge waves are created and spread outwards from the hole . The wall of water , a kilometer high , rushes towards southern Africa at 800 kilometers an hour . Cities on the African coast are totally destroyed and millions of people re drowned .
Before the waves reach South America , the second piece of the comet lands in Argentina . Earthquakes and volcanoes are set off in the Andes Mountains . The shock waves move north into California and all around the Pacific Ocean . The cities of Los Angeles , San Francisco and Tokyo are completely destroyed by earthquakes . Millions of people in the southern half of the earth are already dead, but the north won’t escape for long . Because of the explosions , the sun is hidden by clouds of dust , temperatures around the world fall to almost zero .Crops are ruined . The sun won’t be seen again for many years . Wars break out as countries fight for food . A year later , no more than 10 million people remain alive .
Could it really happen ? In fact , it has already happened more than once in the history of the Earth . The dinosaurs were on the Earth for over 160 million years . Then 65 million years ago they suddenly disappeared . Many scientists believe that the Earth was hit by a piece of object in space . The dinosaurs couldn’t live through the cold climate that followed and they died out . Will we meet the same end ?

| A．Because the land is covered with water |
| B．Because the light and heat from the sun can not reach the earth . |
| C．Because people there can not live at the temperature of zero . |
| D．Because wars break out among countries . |
This morning, a Virgin Atantin 747 Jumbo Jet became the first commercial airplane to fly on biofuel. The short flight from London to Amsterdam used a blend of 20% babassu(棕榈) oil mixed with 80% conventional jet fuel.
What was really exciting about the flight was the fact that the engine did not have to be altered in any way for the biofuel to work While this is a great initial step in trying to reduce CO2(carbon-dioxide)emissions(排放)from airplanes. there are a lot of hurdles (障碍)that still need to be overcome.
First and foremost, unlike the normal fuel used to run airplanes (known as Jet A),biofuel freezes at high altitudes. Also, Jet‘A’fuel burns consistently (at the same pace),which means it provides a safe and reliable fuel for long flights--engineers are not sure if biofuel will be able to do the same.
The biggest hurdle to a full biofuel switch is our ability to be able to grow enough crops that can be converted to biofuel. There are two concerns that scientists have in this matter – the first is that the land to grow the extra crops will come from clearing more of our forests and the second is that since it competes with what we eat, the price of food will go up.
However, Richard Branson of Virgin Airlines, envisions that if biofuel starts to replace oil on a greater basis, it will be manufactured from algae（藻类）produced in sewage treatment plants, not from food sources.
Birgin Airlines is not the only one trying to look for alternative fuel sources. Earlier this year, an Airbus A380 used another alternative fuel－a man-made mix of gas-to-liquid, in one of its four engines. The flight was tested by Rolls Royce (manufacturer of jet engines), in partnership with Shell (an oil company). Rolls Royce is also working with Air New Zealand on a similar project.
While a complete switch to alternative fuel may take years, it is very encouraging to see airlines, oil companies and airplane manufacturers all coming together to try to make it happen!
小题1:．Why does Virgin Airlines try to replace normal fuel with biofuel?
| A．To cut down the flight cost of the company. |
| B．To remove some hurdles for the biofuel to work. |
| C．To reduce CO2 emissions from airplanes. |
| D．To test plane engines on biofuel. |
A Biofuel cannot run for long flights.
B．Biofuel cannot work at high altitudes.
C．Man has not enough land to grow extra crops for biofuel.
D．It’s not easy for sewage treatment plants to manufacture biofuel.
小题3:．One of the hurdles to be overcome for a full biofuel switch is to .
| A．alter the engine for airplanes |
| B．make biofuel burn consistently |
| C．open more land to grow more crops |
| D．develop sewage treatment plants |
| A．there is a long way to go for a complete switch to alternative fuel |
| B．it won’t be long before alternative fuel comes into use |
| C．airlines, oil companies and airplane manufacturers are reliable |
| D．alternative fuel has a bright future |
| A．Biofuel-Alternative Fuel Sources. |
| B．The First Commercial Flight Powered by Biofuel. |
| C．How to Reduce CO2 Emissions from Airplanes. |
| D．Vigin Airlines Trying to Alter Fuel Sources. |
Let children learn to judge their own work. A child who learns to talk does not learn by being corrected all the time. If corrected too much., he will stop talking. He notices a thousand times a day the differences between the language he uses and the language those around him. Little by little, he makes the necessary changes to make his language like other people’s. In the same way, children learn to do all the other things without being taught-to walk, run, climb, whistle, ride a bicycle-compare their performances with those of more skilled people, and slowly make the needed changes.
But in school we never give a child a chance to find out his mistakes and correct them himself. We do it all for his act as if we thought that he would never notice a mistake unless it was pointed out to him, or correct it unless he was made to. Let him work out, with the help of other children if he wants it, what this word says , what the answer is to that problem, whether this is a good way of saying or doing this or not.
If it is a matter of right answers, as it may be in mathematics or science, give him the answer book. Let him correct his own papers. Why should we teachers waste time on such routine(daily) work? Our job should be to help the children when they tell us that they can’t find the way to get to measure their own understanding, how to know what they know or do not know.
小题1: According to the passage, the best way for children to learn things is by ______.
| A．listening to the advice of grown-ups. |
| B．asking adults many questions. |
| C．making mistakes and having them corrected. |
| D．doing as other people do by themselves. |
| A．Give children correct answers. |
| B．Allow children to make mistakes. |
| C．Tell the children what is wrong with their work as often as possible. |
| D．Let children judge their own work. |
| A．encourage children to learn from each other. |
| B．point out children’s mistakes whenever they are found. |
| C．correct children’s mistakes as much as possible. |
| D．teach children more knowledge from book. |
| A．different from learning other skills. | B．the same as learning other skills. |
| C．more important than other skills. | D．unnecessary skills. |
| A．Let Us Teachers Stop Working. | B．Let Children Alone. |
| C．Let Children Correct Their Exercises. | D．Let Children Learn by Themselves. |
