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.
小题1: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
小题2: 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.
小题3: What does the underlined word barred mean?
A.protectedB.allowed .C.markedD.prevented
小题4: 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.
小题5:This text mainly describes how robots will ___________.
A.protect the museumB.set off a siren .

Many strong and out-of-control emotions are recognized as an illness. People who are always very sad have depression (抑郁症); those who worry a lot have anxiety.
But what about anger problems? Anger is largely viewed as a secondary emotion – one caused by other emotions. People are thought to be angry because they are sad, anxious or stressed. In the past, many doctors didn’t accept the idea that anger could be a problem all on its own.
Today, though, a growing number of mental health experts think that anger is a serious problem that needs its own treatment.
How to tell the difference between “normal” anger and “anger problem” is difficult. After all, everyone gets really mad from time to time. Experts point out a few ways.
Disordered anger, as it is sometimes called, tends to be of greater intensity (强度). It takes very little to set off a person with an anger problem, and their responses (反应) are very strong. An example: While most people would get upset if a driver cut them off, someone with disordered anger might try to chase down the car and force it off the road.
And in cases of disordered anger, the person gets angry more frequently and his/her anger lasts longer. For most people, angry feelings disappear quickly. But people with anger problems often stay angry for days, weeks or even years; their feelings of anger don’t disappear over time.
Consequences are also important to consider: Disordered anger often damages people’s lives. “It interferes (干扰) with people’s relationships and their jobs,” says Raymond Chip Tafrate, a US psychologist. “Even their health is affected.”
Anger clearly increases the risk of certain health problems, as many studies have shown. “When a person is angry, their heart beats faster and their blood pressure goes up,” says Howard Kassinove, a professor at Hofstra University in New York. Over time, these changes take their toll on the body, he adds.
Experts suggest that people with an anger problem take anger-management programs. The programs teach people to control their responses to stressful situations through the use of relaxation techniques. The programs sometimes include life-skills training as well: increasing someone’s level of competence (竞争)– whether on the job or as a parent or partner – helps bring down stress and cut angry feelings.
小题1:A person who _________ most possibly has disordered anger in the experts’ opinion?
A.can’t get out of anger quickly
B.is dissatisfied with relationships
C.has high blood pressure
D.is worried about his job
小题2:What does the underlined word Consequences mean?
A.Responses.B.Effects.C.Reasons.D.Feelings
小题3:Which of the following is TRUE according to the passage?
A.Anger is an secondary emotion that makes people sad and stressed.
B.Anger was recognized as an illness by most doctors in the past.
C.A person with an anger problem gets angry more often and easily.
D.The use of relaxation techniques is the best way to manage anger.
小题4: What is the best title of the passage?
A.Can anger be an illness?
B.Is it disordered anger?
C.Can anger influence our life?
D.Is anger management important?

Our spiritual intelligence quotient, SQ (精神智商)helps us understand ourselves and live fuller, happier lives.
  While we’re all born with SQ, most of us even don’t know that we have it.  Luckily, you don’t have to sign up for classes to learn how to enhance(加强) your SQ. Here are some simple steps that can lead you to this new level of understanding:
  Sit Quietly. The step of developing SQ begins in solitude (独处) and silence. To tune in to its whisper, you have to keep away from your busy, noisy, complicated life and make yourself do nothing at all. At home, for example, shut the door of your bedroom, take a few deep breaths and let them out very, very slowly.
  Step Outside. For many people, nature makes their spirit free. Go outside to watch a beautiful sunset. Follow the flight of a bird; watch clouds floating overhead.
  Find An Activity You Enjoy. It’s important to find a hobby that helps you tune in to your spirit. Garden, walk or jog, arrange flowers, listen to music that touches your soul.
  Ask Questions Of Yourself. Some people use their thoughtful time to focus on scriptures (经文). Others ask open-ended (无确定答案的) questions, such as “What am I feeling? What are my choices?” But don’t expect an answer to arrive through  some super-natural form of e-mail. Later that day you’ll suddenly find yourself thinking about a problem from a perspective (角度) you never considered before.
  Trust Your Spirit. While most of us rely on gut feelings (直觉) to warn us of danger, SQ usually nudges (渐渐推动) us, not away from, but toward some action that will lead to a greater good.  
小题1:To enhance your SQ, you should first _______________.
A.stand loneliness and silence
B.make your life simpler and less busy
C.give up the daily things in your life
D.listen more to your whisper
小题2:The underlined phrase “tune in to your spirit” in the fifth paragraph probably means ________________.
A.get your spirit relaxedB.keep up your spirit
C.listen to your spiritD.change your spirit
小题3: What will happen after people ask questions of themselves?
A.People will lead to a greater good.
B.People will think about a problem in a different way.
C.People will expect answers through e-mails.
D.People will keep away from their busy life.
小题4: What is the best title for the passage?
A.Advantages and disadvantages of SQ
B.The relationship between your SQ and you
C.What SQ is and in what ways it can be improved
D.What SQ is and in what ways you can make your life easier

Reading is a good habit, but the problem is there’s too much to read these days and too little time to read every word of it. There are hundreds of skills to help you read more in less time. Here are two skills that I think are especially good.
Preview — if it’s long and hard. Previewing is especially useful for getting a general idea of heavy reading like long magazine articles and business reports.
Here’s how to preview.
Read the first two paragraphs and the last two paragraphs carefully.
Then read only the first sentence of the other paragraphs.
Previewing doesn’t give you all the details. It keeps you from spending time on things you don’t really want - or need - or read.
Skim - if it’s short and simple. Skimming is a good way to get a general idea of light reading like popular magazines or the sports and entertainment of your daily paper.
Here’s how to skim.
Get your eyes to move fast. Sweep them across each line.
Pick up only a few key words in each line.
Everybody skims differently. You and I may not pick up the same words when we skim the same piece, but we’ll get a similar idea of what it’s all about.
小题1: How many skills does the writer introduce to help us in reading?
A.One.B.Two.C.Three.D.Four.
小题2: What should you do if you read a long article according to the writer?
A.Read every word of it.B.Read all the details.
C.Pick up a few key words in each line.
D.Read the first and the last two paragraphs carefully.
小题3: If you read a simple article, which reading skill is better to get the general idea?
A.Previewing.B.Skimming.C.Reading.D.Sweeping.

“Teenager” means a person from 13 to 19 years old. Although they’re young, they have to make many important choices by themselves. Often teachers and parents cannot handle them because they don’t understand and know teenagers, especially their wishes, problems or different moods in a short time. They need to think about questions like these: Should we go to college? What kind of job do I want? However, other people also influence their choices. Who influences teenagers?

It depends on the kind of choice. When teenagers buy things, friends are the most important influence. This is especially true for clothes and music. TV shows, advertisements and parents also influence teenagers. In more serious things, parents are probably the most important influence. Some teenagers say it’s best to regard both parents and friends as influences. James, a seventeen-year-old boy says he’s “just a crazy man”. He also says, “Parents are really important because they can tell you what’s right and wrong.”
But teenagers also feel they need to make choices—to make their own mistakes. As one teenager girl said, “If our parents don’t let us make our own choices, maybe in the future we don’t know how to do it.” And they feel friends can often be a big help, especially because friends sometimes know more about their situation than their parents.
小题1: Why do teenagers sometimes have to make their own choices?
Because the teachers want them to do it.
Because their parents want them to do it.
Because teenagers like to make choices by themselves.
Because teachers and parents don’t understand them well.
小题2: Who influences most to the teenagers when they buy music?
A.Their teachers.B.Theirs parents.C.Their friends.D.Movie stars.
小题3: What does the passage mainly talk about?
Everybody needs to make choices.
Teenagers need to make choices by themselves.
Teenagers know more about TV shows and music.
Teachers and parents should help teenagers as much as possible.

Play is the basic business of childhood, and in recent years research has shown the great importance of play in the development of a human being. From earliest infancy(婴儿), every child needs opportunity and right materials for play, and the main tools of play are toys. The main function of toys is to suggest, encourage and play. To succeed in this, they must be good toys, which children will play with often, and will come back again and again. Therefore, it is important to choose suitable toys for different stages of a child’s development.
In recent years, research on baby development has shown that the standard a child is likely to reach, within the range of his inherited(遗传的)abilities, is largely determined in the first three years of his life. So a baby’s ability to benefit from the right play materials should not be underestimated. A baby who is encouraged, talked to and shown things and played with, has the best chance of growing up successfully.
In the next stage, from three to five years old, curiosity knows no bounds. Every type of suitable toys should be made available to the child, for trying out, experimenting and learning, for discovering his own particular ability: Bricks and jigsaws(七巧板)and construction toys; painting, scribbling(涂鸦)and making things; sand and water play; toys for imaginative and pretending play—the first social games for learning to play and get on with others.
But at the third stage of play development—from five to seven or eight years old— the child is at school. But for a few more years play is still the best way of learning, at home or at school.It is easier to see which type of toys the child most enjoys.
Until the age of seven or eight, play and work mean much the same to a child.But once reading has been mastered, then books become the main source of learning. Toys are still interesting and valuable, which lead up to new hobbies, but their significance has changed to a child of nine or ten years old, toys and games mean, as to adults, relaxation and fun.
小题1: What does the writer want to tell us in the first paragraph?
Children should choose toys by themselves.
Children like playing, but they don’t need any toys.
Children should be given different toys as they grow up.
Children should be given the same toys as they grow up.
58.According to the passage, we can give the child every kind of toys ________.
A.when he is twoB.when he is around four
C.when he is six D.when he is eight
小题2:When a child is seven years old, what is the main source of learning?
A.Toys.B.Books.C.Jigsaws.D.Paintings.
小题3: What is the article mainly about?
A.The importance of schooling.
B.The choice of toys for children.
C.The importance of pre-school education.
D.The role of play in a child’s development.

What is your favorite color? Do you like yellow, orange, or red? If you do, you must be an active person who enjoys life. Do you like blue? Then you are probably quiet, shy, and would rather follow than lead.
Colors do influence our moods (情绪). A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day. On the other hand, black is depressing(令人压抑的). There was a black bridge over the Thames River, near London. The number of people who killed themselves on that bridge used to be larger than on any other bridge in the area -- until it was repainted green.
Light and bright colors make people not only happier but also more active. In the factory, the workers will work better, harder, and have fewer accidents when their machines are painted orange rather than black.

Bamboo (竹子) is one of nature’s (自然) most surprising plants. Many people call this plant a tree, but it is a kind of grass.
Like other kinds of grass, a bamboo plant may be cut very low to the ground, but it will grow back very quickly. A Japanese scientist reported one bamboo plant which grew 1. 5 metres(4 feet) in 24 hours! Bamboo grows almost everywhere in the world except Europe. There are more than 1, 000 kinds of bamboo.
Not all bamboo looks the same. Some bamboo plants are very thin. They may only grow to be a few centimetres wide while others may grow to more than 30 centimetres (1 foot) across. This plant also comes in different colours, from yellow to black to green.
Bamboo has been used to make many things such as hats and kitchen tools( 厨房用具). Because it is strong, bamboo is also used to build buildings.
Many Asian countries have used bamboo for hundreds of years. They often use bamboo for buildings and supporting (支撑) new buildings and bridges while they are being built.
In Africa, poor farmers are taught how to find water using bamboo. These African countries need cheap way to find water because they have no money, and their fields often die from no rain and no water.
