根据短文内容的理解，选择正确答案。

In many high schools, there are strict rules about using mobile phones. If your phone rings in class, for example, the teacher will be very angry.

Every mobile phone has a ringtone (铃声). It tells you that someone is calling you. Now, there is a ringtone called "mosquitotone (蚊子铃声)". Using it, students can receive calls and text messages (短信) in class but the teacher will not realize what is happening. How?

Mosquitotone has a special sound. Only children and teenagers can hear it. As we get older, we are unable to hear some sounds with high frequencies (频率). As a result, a child or teenager can hear the mosquitotone ringtone, but someone of 20 or older can't.

But sometimes, people over 20 can hear the ringtone. One British student's phone uses mosquitotone. In class, the student's phone rang. The 22-year-old teacher looked at the student and became unhappy. "I heard that. You know the rule: no mobile phone in class."

Not all the students are interested in mosquitotone. Jerry Jones, a high school student of 17, says, "Using mosquitotone too often is bad for our hearing. I may use it for pleasure, but not in class. It's unfair(不公平的) to the teachers!"

What do parents think of mosquitotone? "I think it is perfect for places like movie theaters," says Connie Neeson, 44. "Think about it. You're watching a film and someone's mobile phone rings. Mosquitotone is good because many people don't hear it. However, it also has a bad influence（影响） on their study if students use it in class."

（1）、Mosquitotone works because _________.

A、it is very loud B、it has no sound C、it has a beautiful sound D、it is mainly for children and teenagers.

（2）、Which of the following about Jerry Jones is TRUE?

A、He likes watching movies. B、He is a high school teacher. C、He thinks mobile phones are helpful. D、He refuses to use mosquitotone in class.

（3）、The 22-year-old teacher felt unhappy because the student _________.

A、was late for class B、didn't do his homework C、couldn't answer her question D、was using a mobile phone in class

（4）、Connie Neeson thinks that mosquitotone _________.

A、has no bad influence B、is unfair to the teachers C、has its advantage and disadvantage D、can't be used in any public place

（5）、The writer wrote this passage mainly to introduce ________.

A、a strict rule B、a famous school C、a special ringstone D、A popular mobile phone

    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.

Which animal do you think is "the king of the animals", the elephant, the lion or the tiger? They are all large and strong. But I think the tiger is "the king of the animals". If you watch carefully, you can find some black lines on the tiger's forehead(前额). The lines look like the Chinese word "WANG". The word means "the king of the world" in Chinese.
Most of the tigers come from China and India. Tigers are dangerous animals. They look scary(吓人的). They like eating meat. They have yellow fur with black lines. They usually weigh about 200 to 300kg. Tigers can run fast. They run at a speed of 20 meters per second.
Some people think they are dangerous. But they don't know tigers are in danger now. There are only 20 to 30 wild South China Tigers in China and less than 300 in the world. Lots of people kill them for their fur. We should take action to protect them.

Most people hope to have a memory which helps them succeed in study, work and life. Can memory be improved? Luckily, hundreds of studies in the past 50 years have already given us a definite answer.
A healthy lifestyle keeps your brain young and memory sharp. First of all, it is necessary to have a healthy diet. Eating more food rich in B vitamins and Vitamin E, such as vegetables and lean meat, helps you have a better memory. Doing exercise can keep your brain alive, too. Proper exercise provides much needed oxygen for the brain. Running, riding a bike, swimming and even walking two or three times a week are helpful. Moreover, getting enough sleep is important. Only when your brain gets a good rest, can it work well. The healthier your lifestyle is, the better your memory will become, but do not expect a sudden change—it takes a long time to make a difference.
Memory skills help you remember things better. The following three are the most widely used. Chunking is a way of remembering a piece of information by cutting it into smaller ones. For example, to memorize a ten--digit telephone number 2127983630, you can divide the digits into three groups: first 212, then 798, and lastly 3630. This method is far more effective than remembering a string of 10 digits. Organization means organizing information into groups of the the same kind. For example, trees, grass and flowers are plants; tigers, panadas, horses and cows are animals. Imagery is remembering newly learnt information by using your imagination and connecting it with something that you are familiar with.
However, memory skills will hardly work if you don't understand the information. What's more, only a regular review can make the memory last long. That is why students are always advised to go over what they have learnt after one day and then after three days, and then use it as regularly as possible.
Human brains are like muscles that need nutrients and exercise to become stronger. If you make a few lifestyle changes and try some memory skills, you can certainly improved your memory.

Hi, everyone. I'm Tina. I think our life in 2060 will be different from our life at the moment. There will be many robots in my house. Because robots will be cheap. And these robots will help my family do many kinds of work every day. Every morning the clock-robot will ask me to get up. Then the clothing-robot will dress me quickly. Next the kitchen-robot will make breakfast for me. When I get out of the house with my schoolbag, a car-robot will wait for me. After I show it my school ID card, the car will go. And then the car-robot will check my homework. When we get to school, the car-robot will say to me "See you tomorrow, Tina. Good luck."

In the morning, I will have three lessons with my classmates. We'll study on the Internet. We'll use the e-book. The teachers are all robots. They are in different sizes and they can answer any question about any subject. In the afternoon, we'll go to the science lab to have two classes in a new plane. After class, we'll play football with robots. My classmates and robots can all be my friends. Don't you think the life with robots in the future will be fantastic?

The word 'day' has two meanings. When we talk about the number of days in a year. We are using 'day' to mean 24 hours. But when we talk about day and night. We are using 'day' to mean the time between sunrise and sunset. Since the earth looks like a ball. The sun can shine on only half of it at a time. Always one half of the earth is having day and the other half night. A place. is moved from day into night and from night into day over and over by the spinning(旋转)of the earth. At the equator(赤道)day and night are sometimes the same length, they are each twelve hours long. The sun rises at 6 o'clock in the morning and sets at 6 o'clock in the evening. For six months the North Pole is tilted(倾斜)toward the Sun. In those months the Northern Hemisphere(半球)gets more hours of sunlight than the Southern Hemisphere. Days are longer than nights. South of the equator nights are longer than days. For the other six months the North Pole is tilted away from the SUN. Then the Southern Hemisphere gets more sunlight. Days are longer than nights. North of the equator nights ate longer than days. Winter is the season of long nights. Summer is the season of long days.
