Waste can bring a lot of problems. Although China is rich in some resources (资源) , we are short of others, for example, fresh water. It is reported that we will have no coal or oil to use in 100 years. So if we go on wasting our resources, what can we use in the future and where can we move? Think about it. 38. I think we should say no to the students who waste things every day. Everyone should stop wasting as soon as possible.
39. In our everyday life, we can do many things to prevent (阻止) wastefrom happening, for example, turn off the water taps when we finish washing, turn off the lights when we leave the classroom, try not to order more food than we need, and so on. Little by little, everything will be changed. 40. Waste canbe stopped one day, if we do our best.

Many companies use guards and expensive alarm systems to protect their property(财产)。 Soon a new kind of protection will be used- robots. Engineers have been working on the first mobile robots for businesses. The robots will patrol(巡逻) factories, warehoues(仓库)，and museums at night.
The mobile robots will move around slowly on wheels. They will be able to detect people through walls and pick up sounds, such as breaking glass. They can be fixed with lound sirens(警笛) to frighten thieves, or radios to signal police or guards.
To protect a building, a robot will have to move around without knocking into the walls. Information about the building will have to be stored in the robot’s small, built-in computer. A floor map could be programmed into the computer’s memory, for example.
A mobile robot will not be able to do everything. Unlike human guards, it will not be able to climb stairs, open doors, or move along rough ground. It won’t be able to tell the difference between friends and enemies. Because of that, people will have to be barred from the area it patrols.
One kind of mobile robot will be able to “sense” whether a chair or box has been moved and go around it. This robot will also judge size well enough so that it won’t send an alam if a cat crosses the room. And if someone tries to steal this robot, it will sound a loud, painful siren. The three-foot-tall robot will be hard to steal anyway. It will weigh about 200 pounds.
U.S companies pay almost $10 billion a year to protect their property with alarm systems and human guards. Mobile robots may be cheaper.Why is the new kind of robots called mobile robots?
| A．Because they are able to climb stairs. | B．Because they are able to send an alarm |
| C．Because they can open doors. | D．Because they can move around slowly on wheels |
How will a robot get directions for moving around a building?
| A．From a human guard . | B．From a built- in computer. |
| C．From another robot . | D．From radio signals. |
What does the underlined word barred mean?
| A．protected | B．allowed . | C．marked | D．prevented |
According to the text, a mobile robot will NOT be able to ___________.
| A．sense whether something has been moved. | B．sense a cat crossing the room. |
| C．move over rough ground . | D．detect people through walls. |
This text mainly describes how robots will ___________.
| A．protect the museum | B．set off a siren . |
| C．judge the size of a person. | D．patrol buildings. |
Soon computers and other machines will be able to remember you by looking at your eyes! The programme 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) programme is already being tested in shops and banks in the USA, Britain, Spain, Italy and Turkey. Soon, this technology will take the place of 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 hand or even your smell! We already have machines that can tell who you are from your voice or the mark made by your finger.
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 programme can be up to 94% correct, depending on(依靠) how good the technology is. Some programmes 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 computure will be looking at you in the eye. So smile! How does the eye-recognition programme work?
| A．You write your number. | B．You show your ID card. |
| C．You look at the machine. | D．You say your name. |
Why can the programme be up to 94% correct?
| A．Because eyes never change. |
| B．Because hands or fingers can get dirty. |
| C．Because people like the idea of the programme. |
| D．Because the programme is widely used around the world. |
Which of the following is TRUE?
| A．The programme is being tested in Japan. |
| B．Machines with other systems can also tell who you are. |
| C．91% people like the idea of the programme. |
| D．Computers can remember you by looking at your clothes. |
What does Paragraph 4 talk about?
| A．Introduction to other kinds of programmes. |
| B．Advantages of the programme. |
| C．The places where the programme is tested. |
| D．The way how the programme works. |
Researchers have announced the result of two studies on the health effects of the drug aspirin(阿斯匹林). One study shows aspirin can sharply reduce the chance that a healthy, older man will suffer from a heart attack.
The study offered two new results from earlier findings. It said taking one aspirin pill every other day helped only healthy men over the age of fifty. It also said aspirin gave the greatest protection against heart attacks to men with low blood cholesterol(胆固醇) levels.
Earlier in the United States began a major aspirin study in the early 1980s. it included 22,000 healthy men doctors. All were between the ages of forty and eighty-four. More than 11,000 of the doctors took a harmless pill that contained no drug. The men did not know which kind of pill they were taking.
The doctors who took aspirin suffered 44% fewer heart attacks than those taking the harmless pill. 139 men who took aspirin suffered from heart attacks. Ten of them died. 239 men who didn’t take aspirin suffered from heart attacks. Twenty-six of them died.
The researchers said the doctors’ study provides clear proof that taking aspirin can prevent a first heart attack in healthy, older men. They said ,however, the result does not mean every man over the age of fifty should take aspirin. They said aspirin couldn’t help men who do not eat healthy foods, who smoke cigarettes and who are fat. The researchers said men who think they would be helped by taking aspirin should talk with their doctors first. The passage tells us that the new use of aspirin is___________.
| A．to treat heart disease. |
| B．to reduce pain while one suffers from a heart attack. |
| C．to help old people to be more healthy. |
| D．to reduce the chance of a heart attack in old men. |
Aspirin can help those who___________.
| A．work as doctors | B．are under 40 years old |
| C．are fat and smoke cigarettes | D．are older and healthy |
From the experiment we can conclude that about _________ of people who suffered from heart attacks without aspirin died.
| A．7% | B．11% |
| C．19% | D．44% |
