Edison and his assistants came to New York to set up an electric power system. They hoped it would provide enough electricity to light up a part of the great city.
They bought several machines with them. These were called generators(发电机), which produced electricity power for lamps in Edison’s building.
Soon there were lights for the building. Edison lived in a room facing the street and he often worked over night. The light burned brightly and steadily and he often worked over night. People often came and stopped their horse-drawn carriage to look. Everyone knew that Thomas Edison was in town.
First, the inventor and his assistants produced several large generators. A great deal of power would be needed to light up even a small part of the city. Then the workers were busy digging deep trenches in the hard earth below the city streets, and Edison had fourteen miles of wire laid into the trenches. The wire connected each building to a generator.
Setting up an electric power system was not an easy job. It took a year and a half. In September, 1882, the job was finished.
A small group of men stood around Edison inside the power house. The big moment came at last. The inventor, taking a deep breath, pulled a switch. The electric lights flashed up.
“Very good! Very good!” a man nearby shouted to praise Edison for what he had done.
“Sir,” said Edison, “this is only the beginning!” And Edison was right. Soon Edison’s lamp were lighting up cities all over the world.

举一反三
Futurologists(未来学家)predict that life will probably be very different in 2050.
TV channels(频道)will have disappeared. Instead, people will choose a program from a “menu” and a computer will send the program directly to the television. Today, we can use the World Wide Web to read newspaper stories and see pictures on a computer thousands of kilometers away. By 2050, music, films, programs, newspapers, and books will come to us by computer.
Cars will run on new, clean fuels and they will go very fast. Cars will have computers to control the speed and there won’t be any accidents. Today, many cars have computers that tell drivers exactly where they are. By 2050, the computer will control the car and drive it to your destination. Space planes will take people halfway around the world in 2 hours. Today, the United States Space Shuttle can go into space and land on Earth again. By 2050, space planes will fly all over the world and people will fly from Los Angeles to Tokyo in just 2 hours.
Robots will have replaced people in factories. Many factories already use robots. Big computers prefer robots—they don’t ask for pay rises or go on strike, and they work 24 hours a day. By 2050, we will see robots everywhere—in factories, schools, offices, hospitals, shops and homes.
Medical technology will have conquered many diseases. Today, there are devices(设备)that connect directly to the brain to help people hear. By 2050, we will be able to help blind and deaf people to see and hear again.
Scientist will have discovered how to control genes(基因). Scientists have already produced clones(克隆)of animals. By 2050, scientists will be able to produce clones of people, and decide how they look, how they behave and how clever they are. Scientists will be able to do these things, but should they?
小题1:According to the passage, the following can be realized today EXCEPT __________.
A.reading newspapers on a computer |
B.making a space shuttle go into space and land on Earth again |
C.creating cloned animals |
D.choosing TV programs freely from a “menu” |
A.can work 24 hours a day |
B.often ask for more pay |
C.are not clever enough |
D.are often late for work |
A.there will be no blind and deaf people by 2050 |
B.few diseases will attack people by 2050 |
C.devices are connected directly to the brain to help people hear |
D.medical technology will be more effective by 2050 |
A.The author does not support the use of cloning technology. |
B.The author thinks human cloning is impossible. |
C.The author does not really support the idea of human cloning. |
D.The author is quite excited about human cloning. |
The world is quickly running out of room for conventional farming. Vertical farms could be a key to this situation. An 18story vertical farm could feed as many as 50,000 people,all in an area which is the size of the average city block. Vertical farms in the city could cut down on transportation costs as well. Think about the amount of fuel it takes to transport food from farmland to city. The resources saved would be surprising. Besides saving travel time,food would be delivered in fresher condition and with less damage.
There is a growing concern about the use of pesticides(杀虫剂) in agriculture today. But the vertical farm would be a greenhouse type environment, avoiding the need for a large number of pesticides. Vertical farms can be built in a contained space,therefore they are an excellent solution for living well in an environment far different from our own. Hydroponics(水耕法) could be a big part of vertical gardening. This would reduce the amount of soil needed to grow food. Of course,not all food does well with this type of planting,but there are many crops that actually seem to do better.
In some climates,a lack of sunlight creates a short growing season. The solar power option may not work as well here. The addition of grow lights would make it possible to grow crops in vertical gardens in these areas .In other words,we could grow crops in areas where we never could before.
Vertical farms may just be a concept for now,but they are a concept that will solve many of our problems in the future.
小题1:According to the passage, a vertical farm________.
A.is mainly built outwards |
B.is dependent on solar power |
C.is planted on levels upwards |
D.is only an environmental friendly farm |
A.depend far less on sunlight |
B.greatly increase the use of soil |
C.help to protect the limited gardens |
D.reduce the use of harmful pesticides |
A.have been put into use |
B.only use hydroponics to grow food |
C.need less room than conventional farms |
D.may increase the transportation costs |
A.Vertical farms for our future |
B.Ways to deal with future problems |
C.Vertical farms and green skyscrapers |
D.Making Full Use of Our Limited Land |
These people have traveled to the countryside more than an hour from Washington, D. C., to get away from the glow of city lights. That"s because they are attending a star party. Star parties are gatherings where professional and amateur astronomers set up their telescopes and invite people to come learn about the night sky. Getting away from light pollution, or artificial skylight from buildings for example, helps stargazers (看星星的人) see objects in the sky much better.
At this star party, Sean O"Brien of the National Air and Space Museum’s Einstein Planetarium starts off by asking the crowd to simply look up and take in all they can see. He points out plenty of things that can be seen without special equipment. Stars, satellites, and even the Andromeda galaxy(仙女座) can be found if you know where to look.
After that, several dozen astronomers offer close-up views. Each has focused their telescope on a different part of the sky. As kids take a look, the owner gives a mini-lesson.
O’Brien says you can have your own star party at home and learn a lot just by paying attention to what"s happening up above. "Watch the sky as the seasons pass, and you will see that it changes," he says. "Or start with the moon. Notice when and where you are seeing it—maybe even in the early morning while you wait for the school bus. "
小题1:What was it special about the Star Party ?
A.It was organized by the local authority. |
B.It was carried out without any lights. |
C.It was so cold that people chatted to cheer up. |
D.It was held in the town center of Virginia |
a. some invited guests
b. some government officials
c. some experts in astronomy
d. those who were interested in astronomy
e. students who were major in agriculture
A.a, c, d | B.a, d, e | C.b, d, e | D.c, d, e |
A.you"d better escape from pollution and sunlight |
B.you"d better follow Sean O"Brien"s guidance |
C.you"d better buy some advanced equipment |
D.you"d better make use of your imagination |
A.Roman is not built in a day. |
B.No pains, no gains. |
C.All roads lead to Roman. |
D.Time and tide wait for no man. |
In some modern countries it has for some time been fashionable to think that by free education for all — one can solve all the problems of society and build a perfect nation. But we can already see that free education for all is not enough; we find in such countries a far larger number of people with university degree; they refuse to do what they think “low” work; and, in fact, work with hands is thought to be dirty and shameful in such countries. But we have only to think a moment to understand that the work of a completely uneducated farmer is far more important than that of a professor; we can live without education, but we die if we have no food. If no one cleaned our streets and took the rubbish away from our houses, we should get terrible diseases in our towns…
In fact, when we say that all of us must be educated to fit us for life, it means that we must be educated in such a way that, firstly, each of us can do whatever work suited to his brains and ability and, secondly, that we can realize that all jobs are necessary to society, and that is very bad to be ashamed of one’s work. Only such a type of education can be considered valuable to society.
小题1:The writer of the passage thinks that _______.
A.education can settle most of the world’s problems |
B.free education for all probably leads to a perfect world |
C.free education won’t help to solve problems |
D.all the social problems can’t be solved by education |
A.our society needs all kinds of jobs |
B.our society needs free education for all |
C.a farmer is more important than a professor |
D.work with hands is the most important |
A.to choose officials for the country |
B.to prepare children mainly for their future work |
C.to let everyone receive education fit for him |
D.to build a perfect world |
A.the means | B.the system | C.the value | D.the type |
Chief technology officer Justin Rattner showed how personal devices will one day offer advice. “How can we change the relationship so we think of these devices not as devices but as assistants or even companions?” he asked.
Handheld devices could combine already common geographic location technology with data from microphones, cameras, heart and body monitors and even brain scans to offer their owners advice that today only a friend or relative could give.
“Imagine a device that uses a variety of sensors to determine what you are doing at an instant, from being asleep in your bed to being out for a run with a friend, ” Rattner said, “Future devices will constantly learn about who you are, how you live, work and play.’’
Rattner also demonstrated a television remote control that figures out who is holding it based on how it is held, and then learns the viewer’s entertainment preferences.
As the world leader for decades in microchips for servers and desktop computers, Intel is hurrying to catch up in the profitable market for smart phones like Apple’s iPhone and Research in Motion’s Blackberry.
Telephones with e-mail, global positioning and media players are pointing the way to a future where ever more functions are packed into ever smaller mobile devices.
The smart phone industry, including technology giants like LG and Samsung, is likely to sell 270 million phones this year and grow 25 percent in 2011, according to market research company IDC.
“I think you can expect to see features that support context-aware computing starting to appear in Intel products in the near future,” Rattner said.
But analysts say Intel faces an uphill battle getting its microchips into new phones as Nvidia, Marvell and Qualcomm have already made headway with cheap, lower-power processors based on designs by ARM Holdings.
Rattner recognized that questions about privacy and people’s willingness to be intimate with their computers will have to be settled before the future generation of smart phones he described takes off.
“If you think identity threat is a problem today, imagine when your whole context is readily available on the Net.”, he said.
小题1:The future smart phones can do all of the following except _______.
A.giving responses to the moods of the owners |
B.giving proposals like assistants or companions |
C.offering advice to their owners’ friends or relatives |
D.telling the phone holders or carriers where they are |
A.iPhone and Blackberry | B.LG and Samsung |
C.Marvell and Qualcomm | D.Nvidia and ARM Holdings |
A.Intel Corporation has become the world leader in the smar tphone market |
B.Intel Corporation has fallen behind in the profitable market for smart phones |
C.more functions packed into mobile phones will make mobile devices larger |
D.the smart phone industry is likely to grow 25 percent in the year of 2011 |
A.Smart phones and Televisions | B.Context-aware Computing |
C.Personalized Televisions | D.Personalized Smart phones |
