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.

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!
【小题1】 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.

【小题2】 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.

【小题3】 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.

【小题4】 What does Paragraph 4 talk about?

A．Introduction to other kinds of programmes.

B．Advantages of the programme.

What’s your dream vacation? Watching wildlife in Kenya? Boating down the Amazon? Sunbathing in Malaysia? New chances are opening up all the time to visit the world. So we visit travel companies, compare prices, and pay our money.
We know what our vacation costs us. But do we know what it might cost someone else? It’s true that many poorer countries now depend on tourism for foreign income. Unfortunately, though, tourism often harms the local(本地的) people more than it helps them.
It might cost their homes and lands. In Myanmar, 5,200 people were forced to leave their homes among the pagodas(佛塔) in Bagan so that tourists could visit the pagodas.
Tourism might also cost the local people their jobs and dignity(尊严). Local workers often find only low-paying jobs in the tourist industry. And most of the money do not help the local economy（经济）. Instead, money return to the tour operators in richer countries, When the Maasai people in Tanzania were driven from their lands, some moved to poor places of the city. Others now make a little money selling things or acting for photos.
Problems like these were noticed more than 20 years ago. But now tour operators and local governments are working together to begin correcting them. Tourists, too, are putting on the pressure.     
The result is “ethical（合乎职业道德的）tourism”. Ethical tourism has people at its heart. New international agreements and rules can help protect the people’s lands, homes, economies and cultures. The beginnings are small, though, and the problems are complex(复杂的).
But take heart. The good news is that everyone, including us, can play a part to help the local people in the places we visit. Tour operators and companies can help by making sure that local people work in good conditions and earn the money they should get.
They can make it a point to use only locally owned hotel, restaurants and guide services. They can share some money to help the local economy. And they can help the local people plan and manage tourism.
What can tourists do? First, we can ask tour companies to provide information about the conditions of local people. We can then make our choices and tell them why. And while we’re abroad, we can:
Buy local foods and products.
Pay a fair price for goods and services and not bargain for the cheapest price.
Ask before taking photographs of people.
They are not just part of the scenery!
Let’s enjoy our vacation and make sure others do, too.
【小题1】Which of the following is not mentioned?

A．Local people protected the pagodas in Bagan well.

B．Tourists may stay in hotels opened by local people.

C．Local people are mainly provided with low-paying work.

D．Tourists had better not bargain with local people for a cheap price.

【小题2】 The underlined phrase "take heart" means"      ".

A．pay attention

B．take care

C．cheer up

D．give up

【小题3】 According to the passage, the writer thinks          .

A．tourism is not a promising industry

B．dream vacations should be spent abroad

C．the problems caused by tourism are easy to settle

D．tourists should respect local customs and cultures

【小题4】What is probably the best title for the passage?

A．Tourism Causes Bad Effects.	B．Tourism Calls for Good Behavior.
C．Vacations Bring a Lot of Fun.	D．Vacations Cost More Than You Think.

Thinking is something you choose to do as a fish chooses to live in water. To be human is to think. But thinking may come naturally without your knowing how you do it. Thinking about thinking is the key to critical(批判性的) thinking. When you think critically, you take control of your thinking processes（过程）. Otherwise, you might be controlled by the ideas of others. Indeed, critical thinking is at the heart of education.
The word “critical” here has a special meaning. It does not mean taking one view against another view, as when someone criticizes another person for doing something wrong. The nature of critical thinking is thinking beyond the easily seen--beyond the pictures on TV, the untrue reports in the newspapers, and the faulty reasoning.
Critical thinking is an attitude as much as an activity. If you are interested in life and want to dig deeper into it, you are a critical thinker. If you find pleasure in deep thinking about different ideas, characters, and facts, you are a critical thinker.
Activities of the mind and higher-order reasoning（推理）are processes of deep and careful consideration. They take time, and do not go hand in hand with the fast speed in today’s world: fast foods, instant coffee, and self-developing film. If you are among the people who believe that speed is a measure（尺度）of intelligence（智慧）, you may learn something new from a story about Albert Einstein. The first time Banesh Hoffman, a scientist, was to discuss his work with Albert Einstein. Hoffman was too nervous to speak. But Einstein immediately made Hoffman feel comfortable by saying, “Please go slowly. I don’t understand things quickly.” 
【小题1】Critical thinking is important to us because if we do not think critically, _______.

A．it will be hard for us to think naturally and fast

B．we might be controlled by other people’s ideas

C．we will follow the ideas of others naturally

D．we might be fooled by other people’s ideas

【小题2】If you are a critical thinker, you will ________.

A．take one view against another view

B．trust the reports in the newspapers

C．think deeply about different ideas

D．criticize other people for their mistakes

【小题3】 In the last paragraph, “something new” suggests that ________.

A．speed can improve intelligence

B．intelligence is not decided by speed

C．the smarter you are, the faster you do things

D．the faster you do things, the smarter you become

    Colourful fruit and vegetables are good for our health. Their natural colours help protect our bodies from disease(病，疾病). Think about the colours of fruit and vegetables: the red of tomatoes, the orange of carrots, the green of kiwi and the purple of grapes.
You can enjoy eating fruit and vegetables of all colours---green, yellow, blue, purple, and white. Each colour is important to our health. These colours work together to protect our bodies. Scientists have studied them and discovered the good of colourful fruit and vegetables. The list below shows the good of some colours in fruit and vegetables:
Red gives us a healthy heart. It can reduce(减少，降低) heart disease. Red helps improve our memory(记忆力).
Yellow is good for our eyes.
White can reduce cholesterol (胆固醇) .
Green is good for our eyes, too. It also gives us strong bones and teeth.
Blue helps us keep a good memory as we grow old. It also help fight heart disease. So when you are buying or eating fruit and vegetables, remember to try different colours of fruit and vegetables.

When you are learning English, you find it not clever to put an English sentence, word for word, into your own language. Take the sentence "How do you do?" as an example. If you look up each word in the dictionary, one at a time, what is your translation (翻译)? It must be a wrong sentence in your own language.
Languages do not just have different sounds, they are different in many ways. It’s important to master(掌握) the rules(规则) for word order (顺序) in the study of English, too. If the speaker puts words in a wrong order, the listener can’t understand the speaker’s sentence easily.Sometimes when the order of words in an English sentence is changed, the meaning of the sentence changes. But sometimes the order is changed, the meaning of the sentence doesn’t change.
Let’s see the difference between the two sentences:"She only likes apples. " "Only she likes apples. "
When you are learning English, you must use it as the English speaker does.
【小题1】From the passage we know that _______when we are learning English.

People cannot reach an agreement on the use of science and technology. For example, will radiation from electronic equipment destroy the environment? Should medical scientists change gene structures to prevent genetic disease or to create “more perfect” human beings? While people are arguing about these and others, technology continues to influence our everyday lives—the home, health and education, entertainment and communication, and so on.
Some people carry on active social lives with computers —their own or the ones in public places like cafes, social centers, libraries, and so on. Communicating with others in chat rooms,  computer users can get to know people they might never meet in traditional ways. With live online video connections, two people with cameras in their computers can see and talk to each other from separate places.
With modern telephone technology, most people stopped writing lettters—especially personal letters and notes. But now, writing to communicate has returned in electronic form, or e-mail, which is a way of sending messages from one computer to another. For some computer users, the wish to communicate intelligently or creatively with others makes them want to write better.
Computer technology has also made it possible to run a house electronically. From turning lights on and off to starting the coffee and cooking the hot meal, computers are taking care of people at home. Many modern machines have computer chips that allow their owners to program them. For instance, you can “instruct” a microwave oven how to cook a dish. Most entertainment equipment operates with computer technology too. Computers can even start cars automatically so that on cold winter mornings you can get into a warmed-up vehicle and drive off.
Although much of the technology in our everyday lives has good effects, there are some uses that raise questions. For example, are interactive media ( i.e., a combination of television, telephone, and computer) going to control minds, cause people to forget about family life and personal relationships? What effects will the genentic engineering of food have on people’s health? High-tech medical treatments can make a person live a much longer life, but can they improve the health and happiness of human beings? Only time will tell, but, in the meantime, science and technology will continue to move forward. 
【小题1】What does the underlined word “ chips” mean?

A．thin pieces of potatoes

The Bermuda Triangle(百慕大三角)is in the Atlantic Ocean, near Florida in the USA. During the past 60 years, more than 1,000 seamen in ships and pilots in planes have lost their lives. It is known as “The Triangle of Death”for its strange seawater and sudden storms. What’s the strangest is the light of the seawater, which looks so bright that it can be seen even from an outer spaceship.
　　At 2:00p.m. on Dec. 5, 1945, five planes took off in fine weather from the airport of Florida, on a training task. Two hours later, the leader in the sky radioed that he was “completely lost”. Then there was silence. Another plane was sent to look for them and also disappeared.
　　One of the largest ship that had disappeared in the triangle was an American coal ship, 500meters long. The weather was good, and there were no messages for help before it was “gone”. No broken ships or dead bodies have been found so far.
　　No one is able to tell how all these accidents have happened. A group of Japanese scientists were there to see what it was really like in 1995, but nothing has been heard of them ever since.
