Soon computers and other machines will be able to remember you by looking at your eyes! The program works because everyone’s eyes are different. So in the future you won’t have to remember a number when you want to use a machine or take money out of a bank. You’ll just have to look at the machine and it will be able to tell who you are.
The eye-recognition(眼睛识别) program is already being tested in shops and banks in the USA, Britain and France. Soon, this technology(技术) will change all other ways of finding out who people are.
However, scientists are working on other systems. Machines will soon be able to know you from the shape of your face or hands or even your smell! We already have machines that can tell who you are from your voice or the mark made by your fingers.
Eye-recognition is better than other kinds because your eyes don’t change as you get older, or get dirty like hands or fingers. And even twins have different eyes, so the program can be up to 94％ correct, depending on(依靠) how good the technology is. Some programs may only be right 51％ of the time. In Britain, it was found that 91％ of people who had tried it said that they liked the idea of eye-recognition.
In the future your computer will be looking at you in the eye. So smile!
【小题1】 How does the eye-recognition program work?
| A．You type in your number. | B．You say your name. |
| C．You look at the machine. | D．You show your ID card. |
| A．Because eyes hardly change. |
| B．Because the program is widely used around the world. |
| C．Because people like the idea of the program. |
| D．Because hands or fingers can get dirty. |
| A．Remembering smells. |
| B．Remembering eyes. |
| C．Remembering fingerprints. |
| D．Remembering the shape of faces. |
| A．The program is being tested in Japan. |
| B．Computers can remember you by looking at your clothes. |
| C．91％ of people in Britain don’t like the idea of the eye-recognition program. |
| D．Machines with other systems will also tell who you are in the future. |

Carbon monoxide poisoning (一氧化碳中毒) causes death and injuries around the world. This gas is a problem in all parts of the world that experience cold weather. A few years ago, America’s Centers for Disease Control (C. D. C.) studied deaths linked (联系) with carbon monoxide poisoning. It found that the number of carbon monoxide deaths in the United States was greatest in January. The C.D.C. also found that carbon monoxide kills more than four hundred Americans each year. And, it said more than twenty thousand people are taken to hospital for treatment of health problems linked with the gas.
Carbon monoxide is called the silent killer because people do not know it is in the air. The gas has no color, no taste and no smell. It does not cause burning eyes. And it does not cause people to cough. Yet, carbon monoxide gas is very deadly (致命的). It steals the body’s ability to use oxygen.
Carbon monoxide makes it difficult for the blood to carry oxygen to body tissues (血管). It does this by linking with the blood. When the gas links with the blood, the blood is no longer able to carry oxygen to the tissues that need it. Damage (损害) to the body can begin very quickly from large amounts (数量) of carbon monoxide.
How quickly this can happen depend on how long a person is breathing the gas and how much gas he or she breathes in.
Carbon monoxide poisoning has warning signs(标志). But people have to be awake to realize them. Small amounts of the gas will cause a person’s head to hurt. He or she may begin to feel tired. Their stomachs may feel sick. The room may appear to be turning around. The person may have trouble thinking clearly.
People develop serious headache as the amount of the gas continues to enter their blood. They will begin to feel very tired and sleepy. They may have terrible stomachache.
Doctors say carbon monoxide influences people differently. For example a small child will experience health problems or die much sooner than an adult. The general health of the person or his or her age can also be important.
【小题1】The damage of carbon monoxide to the body has something to do with _____.
| A．the amount a person breathes in |
| B．whether a person is healthy |
| C．how many signs a person finds |
| D．ages of people |
| A．burning eyes | B．bad cough |
| C．serious headache | D．high fever |
| A．Carbon monoxide poisoning seldom happens in cold areas. |
| B．Twenty thousand Americans are killed by carbon monoxide each year. |
| C．Most people know whether there is carbon monoxide in the air. |
| D．Carbon monoxide stops the blood from carrying oxygen to body tissues. |
| A．Warning signs that carbon monoxide poisoning has. |
| B．Reasons why carbon monoxide can cause person’s death. |
| C．The damage of carbon monoxide and how it works. |
| D．Influences of carbon monoxide on children and adults. |
Sales of laptop computers passed desktops in the U.S. for the first time ever this fall, according to market-research firm IDC. That's bad news for backs, necks and shoulders.
Laptops are bad for our body. When you work at a computer, the keyboard should be at elbow height and the monitor should be roughly at eye level, so you can sit well in a chair. But most users simply set their laptops on a desk or table. The keyboard is too high, which makes your arms reach up, your shoulders feel tired and your wrists bend down. The monitor is too low, which pulls your head and neck forward and down and your back may feel hurt.
That's OK if you use your laptop for a short time. But if you use one for hours without stopping – as do millions of college students, business travelers, telecommuters, video-gamers and growing numbers of office workers – your body may feel hurt. Ergonomics experts have warned about laptop problems for years. But people still like laptops better than the desktops. And they use laptops anywhere – in bed, on the floor – in all kinds of positions.
“How can a mouse or a keyboard hurt you?” says Thomas Caffrey, the founder of Myofactors LLC, “Wrong positions can be bad for your body. As time goes by, a wrong position can lead to pain in the neck, shoulders, back and arms, as well as headaches.”
【小题1】When you work at a computer, the keyboard should be ________.
| A．at elbow height | B．at eye height |
| C．on a desk | D．on a table |
| A．for a short time | B．to play video games |
| C．for hours without stopping | D．to buy things on the Internet |
| A．are not so popular as the desktops |
| B．are more popular than the desktops |
| C．are not bad for our body |
| D．have no mouse now |
| A．people’s sight lower | B．people have cancer |
| C．people’s arm longer | D．people feel pain in the body |
| A．When you use a laptop, you should put your monitor at eye height. |
| B．Laptop computers sold more than desktops this autumn. |
| C．To keep healthy, you should use laptop computers. |
| D．Business travelers often use the laptop computers for a long time. |
Can plants eat people? Probably not, but there are many plants that eat meat. Some of them are big. And they can eat small animals. One famous meat-eating plant is the Venus flytrap(捕蝇草).
The Venus flytrap is a very strange plant. It grows in dry parts of the United States. Its leaves are like the pages of a book. They can open and close very quickly. Inside the leaves, there are three small hairs. If a fly touches one of the hairs, the leaf closes quickly. The fly cannot get out. In about half an hour, the leaf presses the fly until it is dead. Then, the plant covers the fly. Slowly, the plant eats the fly.
Why do plants do it? Most plants get what they need from the sun, the air, and the ground. In some places, the ground is very poor. It doesn't have all these important things, especially nitrogen(氮). Animal meat has a lot of nitrogen, so some plants eat meat to get what they need. Let's hope that some of the bigger plants don't get the same idea!
【小题1】The Venus flytrap is a kind of _________.
| A．plant | B．animal | C．food | D．meat |
| A．挤压 | B．关上 | C．打开 | D．松开 |
| A．Because plants are dangerous to animals. |
| B．Because animals are dangerous to plants. |
| C．Because plants want to get what they need from animal meat. |
| D．Because plants want to protect themselves against animals. |
Scientists say there are seven kinds of food that people should eat every day. They are: (1) green and yellow vegetables of all kinds; (2) citrus(柑橘类)fruits and tomatoes; (3) potatoes and other fruits and vegetables; (4) meat of all kinds, fish and eggs; (5) milk and foods made of milk, like cheese and ice-cream; (6) bread or cereal(谷类), rice is also in this kind of foods; (7) butter, or something like butter, with fat(脂肪)。
People in different countries in the world eat different kinds of things. They also eat different kinds in a day. In some place people eat once or twice a day; in other countries, people eat three or four times a day. Scientists say that these differences are not important. It doesn’t matter if a person eats dinner at 4 o’clock in the afternoon or at eleven o’clock at night. The important thing is that every day a person must eat something from each of the seven kinds of food. The most important thing is that we must find some ways to help the hungry people and make the people have right kinds of food, make them strong and healthy

Dear editor（编辑）
I live in a beautiful city. Many visitors come to my city. There are so many colorful peacocks(孔雀)here .The peacocks mostly live on the grass land of Dongfeng Square（广场）
They are given food freely by visitors ,They usually throw food to them ,and don’t think about at all whether the food is right or not. Some of the peacocks became ill, some even died after eating the bad food given by the visitors . I’m sure most of the visitors who throw food to the peacocks really like the birds ,but don’t realize(意识到)that they may be doing them harm (伤害).The visitors should be told that what have done is very harmful to the birds , and this kind of thing must be stopped from happening Perhaps we can build some small shops beside Dongfeng Square to sell peacock food .For us every person, it’s our duty to give more love to these beautiful birds and to look after them carefully.
Yours,
Sun Yan
