The machine had a computer inside it, and this computer could do wonderful things: it could weigh people very accurately; it could tell them their weight in their own language; and it could tell them what they should eat to reduce their weight.
The manufacturer decided to try out his machine before he sold it to the shops.
He looked around for a good place to put it and finally decided on an airport. There were always people at an airport from many different countries.
The first person to use the machine was an Italian woman. She stood on the machine, put a coin in and waited to hear her weight.
The machine took only a second or two to weigh her, decide on her nationality and the language she spoke, and figure out what kind of food she should eat.
“Good morning, madam,” it said in perfect Italian. “Your weight is 72 kilos, three more than it should be for a woman of your height, age and nationality. This is because you have been eating too much spaghetti. I suggest you eat more fruit and vegetables. Please have a nice day”.
The second person to use the machine was a Chinese girl. She stood on the machine, put a coin in and waited to hear her weight.
“Good morning, Miss," the machine said in perfect Chinese. "Your weight is 38 kilos, exactly the correct weight for your height, age and nationality. Continue to eat what you are eating. Please have a nice day.”
The third person to use the machine was a huge Australian woman. She walked up to the machine and looked at it for a long time. At last she found the courage to stand on the machine and put a coin in. The machine spoke immediately. “Good morning. Will one of you ladies please get off?”
小题1: What could the computer do?
| A．Weigh and talk to people. | B．Translate information. |
| C．Give them diet pills. | D．Make them lose weight. |
| A．She was a little too light. | B．She was a little too heavy. |
| C．She disliked spaghetti. | D．She couldn’t speak Italian. |
| A．She should eat more. | B．She could speak Chinese. |
| C．She would have a nice day. | D．She was fine. |
| A．She was unwell. | B．She was courageous. |
| C．She was too heavy. | D．She had dieted well. |
At very high levels, radiation can kill an animal or human being at once by killing plenty of cells in important organs(器官). Even the lowest levels can do serious damage. There is no level of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and when they are killed at once. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They reproduce themselves in an unusual way. They can grow into cancer. Sometimes this does not show up for many years.
This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the knowledge of the person at the time that damage has occurred. A person can be irradiated(放射治疗) and feel fine, then die of cancer five, ten, or twenty years later as a result. A child can be born weak or easy to get serious illness as a result of radiation absorbed by its grandparents.
小题1:According to the passage, the danger of nuclear power lies in .
| A．nuclear mystery | B．radiation detection |
| C．radiation level | D．nuclear radiation |
| A．when it kills a few cells |
| B．because the killed cells can’t be replaced |
| C．if it damages a few cells |
| D．unless the damaged cells can reproduce themselves |
| A．Radiation can hurt us. | B．Radiation is a subject scientists work on. |
| C．Radiation is a mystery. | D．Radiation is the source of cancer. |
There’s a catch, of course. You have to live near enough to a major city to get broadband Internet. If you don’t, it’s slow dial-up access for you. And for those living really far out, there may be no Internet access at all.
Technology experts often talk about the “last mile” problem, which refers to the difficulty of bringing Internet access to remote locations. In cities and suburbs, it’s relatively easy to provide access for everyone. It is much more difficult to deliver access to those living far from cities, especially in de
veloping countries. Internet service providers, for their part, have been reluctant to provide access to sparsely(稀疏地) populated areas. The handful of Internet users they would reach wouldn’t cover the expense.But every year, technological advancements allow of more and more Internet users. Most broadband connections today run over existing cable TV and telephone lines although these technologies aren’t available everywhere. Some companies have delivered the Internet over standard power lines. Advancements in cheaper, more efficient fiber optics cables(光纤电缆) promise to bring extremely fast Internet connections to more users.
Still, the “last mile” problem remains hard to deal with. There will always be somewhere that doesn’t have an affordable broadband connection. But someday that might not matter. If the rapid progress in cell phone technology is any indication(迹象), it may not be too long before an Internet connection simply follows you wherever you go.
小题1:The underlined part “ a catch” (in Paragraph 2) probably means “________”.
| A．a rare challenge | B．a desirable plan |
| C．an efficient device | D．a hidden problem |
| A．Internet connection has not been popular in most cities. |
| B．Internet service providers care about rural customers. |
| C．Computer is popular in developing countries. |
| D．It is hard to bring Internet access to users in remote areas. |
| A．make TV and telephone available everywhere |
| B．bring great change to people’s everyday life |
| C．make it possible for more people to use the Internet |
| D．bring faster Internet connections to users |
| A．The broadband connection’s getting faster. |
| B．More and more Internet users. |
| C．More and more Internet connections. |
| D．The rapid progress in cell phone technology. |
In this class a little German boy, who does not speak 28 ，cried all the time at first and now cries occasionally.
The Monday of the second week the little fellow just cried and cried. He was sitting 29 Matthew. I thought Matthew was going to start 30 and join in. I stood by and watched, ready for the rescue. Matthew kept turning around and 31 the boy. Then he reached his hand back and 32 him on the leg. He was comforting the boy! Later Matthew was playing with a 33 and the boy with blocks. Actually he was just standing by and crying. Matthew drove his truck over to the blocks, 34 it, picked up a few of the blocks and started handing them to 35 . They then together started 36 towers on the table and the little boy 37 crying．It seemed 38 Matthew knew what the little guy needed．Here was the little guy，who can’t speak English，and Matthew，who 39 playing together，like they were best 40 .
One of the days when I stayed，they were at lunch and Matthew was 41 at the table. I pulled up a chair to sit next to him．He smiled，then grabbed his book bag and took off running 42 the cafeteria．I took off after him．When we reached the wall he just giggled (咯咯笑)，turned around and looked at me． I bent 43 to blame him for leaving his seat and running. He suddenly 44 a big wet kiss right on my cheek and smiled at me．All I could do was to take his hand and 45 him back to his seat．Then I turned my back and couldn’t help laughing.

Time passes very quickly. Some students say they don’t have 26time to review their lessons. It is 27 they don’t know how to make use of their time. They waste it in going to theatres or playing, and 28 other useless things. Why do we study everyday? Why do we work? Why do most people 29 take buses instead of walking? The answer is very 30 .We wish to save time because time is31.
Today we are living in the 21st century. We 32 time as life. When a person dies, his life ends. Since life is short, we must 33 our time and energy to our study so that we 34 be able to work and live well in the future. Laziness is the 35 of time, for it not only brings us 36, but also does other 37 to us. If it is necessary for us to do our work today, 38 we do it today and not 39 it until tomorrow. Remember that time is much more 40.
