Philo Farnsworth was a man who made it possible for one of the most important communication devices — television to be created. Philo was born on August 19th, 1906, near Indian Creek in the western state of Utah. He attended a very small school near his family’s farm. He did very well in school. He asked his teacher for special help in science. The teacher began helping Philo learn a great deal more than most young students could understand.
One night, Philo read a magazine story about the idea of sending pictures and sound through the air. Anyone with a device that could receive this electronic information could watch the pictures and hear the sound. The magazine story said some of the world’s best scientists were using special machines to try to make a kind of device to send pictures.
14-year-old Philo decided these famous scientists were wrong and that mechanical devices would never work. He decided that such a device would have to be electronic. Philo knew electrons could be made to move extremely fast. All he would have to do was to find a way to make electrons do the work.
Very quickly Philo had an idea for such a receiver. It would trap light in a container and send the light on a line of electrons. Philo called it “l(fā)ight in a bottle”.
Several days later, Philo told his teacher about a device that could capture pictures. He drew a plan for it, which he gave his teacher. Philo’s drawing seemed very simple, but it clearly showed the information needed to build a television. In fact, all television equipment today still uses Philo’s early idea.
Philo Farnsworth was only 14 years old then. He knew no one would listen to a child. In fact, experts say that probably only ten scientists in the world at that time could have understood his idea.
On September 7th, 1927, Philo turned on a device that was the first working television receiver. In another room was the first television camera. Philo had invented the special camera tube earlier that year.
The image produced on the receiver was not very clear, but the device worked. In1930, the United States government gave Philo patent documents. These would protect his invention from being copied by others.
56. Before he was 14 years old, _______________.
A. Philo had formed the idea of sending pictures and sound through the air
B. Philo had learned a great deal in science from his father
C. Philo had helped his parents on their family’s farm
D. Philo had had a very strong interest in science
57. How did Philo get the idea of inventing a television?
A. By learning from his science teacher.
B. By reading a story about the idea in a magazine.
C. By thinking hard himself.
D. By using his knowledge about electrons.
58. Philo referred to “ _________ ” when he called something “l(fā)ight in a bottle”.
A. a container sending pictures and sound through the air
B. a light box with a line of electrons in a bottle
C. a receiver that held light and sent it on a line of electrons
D. a way to make electrons send pictures
59. We can infer from the passage that _________________.
A. without his teacher’s help, he would never have become interested in science
B. he made the first working television receiver and the first television camera himself
C. Philo’s early ideas about the television could not be understood by most people of that time
D. his invention was recognized and protected immediately he made it
60. In the passage, the author mainly tells us _______________.
A. that Philo Farnsworth was a great inventor
B. when and where the television was invented
C. who made it possible to create television
D. how Philo Farnsworth invented the television

Sometimes, the simplest ideas are the best. For example, to absorb heat from the sun to heat water, you need large, flat, back surfaces. One way to do that is to build those surfaces specially, on the roofs of buildings. But why go to all that trouble when cities are full of black surfaces already, in the form of asphalt(柏油) roads ?
Ten years ago, this thought came into the mind of Arian de Bondt, a Dutch engineer. He finally persuaded his boss to follow it up. The result is that their building is now heated in winter and cooled in summer by a system that relies on the surface of the road outside.
The heat-collector is a system of connected water pipes. Most of them run from one side of the street to the other, just under the asphalt road. Some, however, dive deep into the ground.
When the street surface gets hot in summer, water pumped through the pipes picks up this heat and takes it underground through one of the diving pipes. At a depth of 100 metres lies a natural aquifer(蓄水層) into which several heat exchangers（交換器）have been built. The hot water from the street runs through these exchangers, warming the groundwater, before returning to the surface through another pipe. The aquifer is thus used as a heat store.
In winter, the working system is changed slightly. Water is pumped through the heat exchangers to pick up the heat stored during summer. This water goes into the building and is used to warm the place up. After performing that task, it is pumped under the asphalt and its remaining heat keeps the road free of snow and ice.
Which of the following is true according to the first two paragraphs ?
Arian de Bondt got his idea from his boss.
Large, flat, black surfaces need to be built in cities.
The Dutch engineer’s system has been widely used.
Heat can also be collected from asphalt roads.
For what purpose are the diving pipes used ?
A. To absorb heat from the sun. B. To store heat for future use.
C. To turn solar energy into heat energy. D. To carry heat down below the surface.
From the last paragraph we can learn that __________.
A. some pipes have to be re-arranged in winter
B. the system can do more than warming up the building
C. the exchangers will pick up heat
D. less heat may be collected in winter than in summer
What is most likely to be discussed in the paragraph that follows ?
A. What we shall do if the system goes wrong.
B. What we shall do if there are no asphalt roads.
C. How the system cools the building in summer.
D. How the system collects heat in spring and autumn.

I am sure that everybody in his/her life has used computers. Nowadays you can feel their presence everywhere at home，at school，at work and they certainly make life easier．On the other hand，there are people who can’t work with them．
Anyway，I believe their presence is a good thing. Life with them seems easier, less difficult and more comfortable You can use them to choose your meal，to withdraw your money, and also save your time，because these operations are all controlled by computers. Therefore you can hardly imagine the modern world without them；the whole planet seems to be one big computer society．
Nevertheless，problems can often appear in this area, too．To have a computer means you have to be quite well－off and have the necessary skills to use it．However，think about questions like “Are computers so available for everyone, or rich and poor people，for people from villages and people from cities. Aren’t they too expensive？Is everyone able to learn how to use them and not everyone has the chance to access and work with them，how could everything in the future be dependent on them？”Therefore，I think our society will be split into two parts．One part will work with them and enjoy the benefits that computers can bring and the other part will be pushed out and will actually be far behind the other group．
Another question that bothers me is，on the one hand，computers are important and good things in our life，but they aren’t everything．They are good as a help at school，quite often as entertainment，especially for young people，as an necessary tool to help in research etc，but I think we shouldn’t be so dependent on them，because computers are only machines and machines can’t feel anything be human and sympathetic，and every action performed by computer can be interfered with another person，which could cause these machines to crash or work badly．
In conclusion，I would like to say I am not against computers．I use computers，too，but people should be wary all the time．
【小題1】By saying “wary”（In the last paragraph）,the writer is trying to say “People should_______.
| A．be strongly for the use of computers because of its convenience |
| B．be careful with computers that will also cause problems |
| C．master more necessary computer skills |
| D．not do something that causes computers to work badly |
| A．a(chǎn)sking questions for people to think about |
| B．giving examples to support his argument |
| C．raising questions and answering them |
| D．expressing his opinion directly |
| A．to encourage us to use computers in our society |
| B．to advise us to say no to computers from now on |
| C．to remind us to care about the problems that computers bring. |
| D．to inform us that the computer has become a necessary part of our life |
