Many everyday American expressions are based on colors.
Red is a hot color. Americans often use it to express heat. They may say they are red hot about something unfair. When they are red hot they are very angry about something. The small hot tasting peppers found in many Mexican foods are called red hots for their color and their fiery taste.
Pink is a lighter kind of color. People sometimes say they are in the pink when they are in good health. It probably comes from the fact that many babies are born with a nice pink color that shows that they are in good health.
Blue is a cool color. The traditional blues music in the United States is the opposite of red hot music. Blues is slow, sad and soulful. Someone who is blue is very sad.
The color green is natural for trees and grass. But it is an unnatural color for humans. A person who has a sick stomach may say he feels a little green. A passenger on a boat who is feeling very sick from high waves may look very green. If a person is green at his job, he may be a newcomer and inexperienced. Sometimes a person may be upset because he does not have something as nice as a friend has, like a new sports car. That person may say he is green with envy. Some people are green with envy because their friend has more dollars.

Fahad Azad, an engineer in India, invented a robot named DuctBot．The toy-car sized DuctBot measured 23 centimeters in length, 19 centimeters in width and 9 centimeters in height and weighs just two kilograms．
The robot is designed to snake through dark, narrow air conditioning ducts （管道） and clean them．A pair of LEDs fitted on the robot light up the dirty scenery, so it can be captured （抓拍） by a camera．
In order to control it more easily, Mr. Azad chooses to fix DuctBot on wheels．The robot can clean off lots of dirt, as well as dead pigeons and insects．Keeping indoor air in good quality and monitoring carbon-dioxide levels in buildings with central air conditioning is a challenge．It is important in some places where clean air can mean a difference between life and death, such as hospitals．Dirty air has a bad influence on people's health．
EPSCO, a Dubai-based company which specializes in improving indoor air quality, read about Mr. Azad's invention in a national newspaper after he had won an international robotics competition．EPSCO had cleaning equipment, but it needed someone to get into those ducts to do the dirty, dangerous work．Across India, for example, the task still falls to children．They are small enough to go through those ducts．
In 2005, Mr. Azad who was still at university decided to do something about it．Six years later his own company, Robosoft Systems, has Bluestar, EPSCO and the Indian Navy, some leading air condition makers, as partners．
Mr. Azad and his ten employees are currently exploring robot designs to examine oil tanks or sewage （污水）pipes．Their biggest challenge is to make the robots user-friendly enough．Mr. Azad hopes that the robot could eventually be operated not by engineers but by workers．There will be lots of difficulties they need to overcome in the future．What can we learn about Ductbot?
| A．It is a toy car and popular with children． |
| B．It is designed to move like a snake in the ducts． |
| C．many LEDs are fitted on it to tell its location． |
| D．It is actually a camera to capture dirty scenery． |

An eighteen-year-old high school student from Utah won the top prize in the Intel Science Talent Search in the United States. The winner received a computer and a scholarship for a college education.
More than 1,500 students from across the country entered projects in the competition this year. Their research included chemistry, medicine, physics, mathematics, engineering, and computer science—almost every area of science.
Forty students were invited to Washington, D.C. for the final judging. A group of scientistsjudged them on their research abilities, critical thinking skills and creativity. The judges alsoquestioned the students about scientific problems before deciding on the winners.
The top winner received 100,000 dollars for college. Shannon Babb of American Fork High School studied the water quality of tile Spanish Fork River in Utah for six years. She found that people have a harmful effect on the river through human activity, including agriculture. And she suggested ways to improve the water quality in the future. These include educating the public not to put household chemicals down the drains（下水道）, which lead to the river eventually.
Seventeen-year-old Yi Sun of the Hanker School in San Jose, California, earned the second place. He won a 75,000-dollar scholarship for new discoveries about a mathematical theory known as random walks. His work could help computer scientists and chemists. Yi Sun was born in China.
The third-place winner was also seventeen and born in China. Yuan “Chelsea” Zhang of Montgomery Blair High School in Rockville, Maryland, won a 50,000-dollar scholarship. She researched the molecular genetics（分子遗传学）of heart disease. Her findings could aid the development of new medicines.

You have probably heard of the Mozart effect. It’s the idea that if children or even babies listen to music composed by Mozart, they will become more intelligent. A quick Internet search reveals plenty of products to assist you in the task. Whatever your age there are CDs and books to help you taste the power of Mozart’s music, but when it comes to scientific evidence that it can make you more clever, the picture is more mixed.
The phrase “the Mozart effect” was made up in 1991, but it was a study described two years later in the journal Nature that sparked real media and public interest about the idea that listening to classical music somehow improves the brain. It is one of those ideas that sound reasonable. Mozart was undoubtedly a genius himself; his music is complex and there is a hope that if we listen to enough of it ,we’ll become more intelligent.
The idea took off, with thousands of parents playing Mozart to their children, and in 1998 Zell Miller, the Governor of the state of Georgia in the US, even asked for money to be set aside in the state budget so that every newborn baby could be sent a CD of classical music. It was not just babies and children who were exposed to Mozart’s music on purpose, even an Italian farmer proudly explained that the cows were played Mozart three times a day to help them to produce better milk.
I’ll leave the debate on the impact on milk yield to farmers, but what about the evidence that listening to Mozart makes people more intelligent? More research was carried out but an analysis of sixteen different studies confirmed that listening to music does lead to a temporary improvement in the ability to handle shapes mentally, but the benefits are short-lived and it doesn’t make us more intelligent.
What can we learn from paragraph 1?
| A．Mozart composed many musical pieces for children. |
| B．Children listening to Mozart will be more intelligent. |
| C．There are few products on the Internet about Mozart’s music. |
| D．There is little scientific evidence to support Mozart effect. |
Why did many people believe in the idea of Mozart Effect?
| A．Because a study described it in the journal Nature. |
| B．Because Mozart himself was a genius. |
| C．Because Mozart’s music is enjoyable. |
| D．Because Mozart’s music makes people relaxed. |
The underlined sentence in paragraph3 suggests that .
| A．people were strongly against the idea |
| B．the idea was accepted by many people |
| C．Mozart played an important part in people’s life |
| D．the US government helped promote the idea |
What is the author’s attitude towards the Mozart effect?
| A．Favorable | B．Objective |
| C．Doubtful | D．Positive |
What would be the best title for the passage?
| A．Listening to Mozart , necessary? | B．What music is beneficial? |

During the last fifteen years of my mother's life she suffered with Alzheimer's disease (老年痴呆). Until then she had been a bright, cheerful woman deeply interested and involved in the world around her. I would go home to visit her in Virginia and she would look at me in a puzzled way and ask, “Who are you?” I would answer, “I'm your son.” “Where do you live?” She would ask. “In California”, I would tell her. “Isn't that interesting,” she would say, “I have a son in California.”
She seemed simply forgetful and confused at the beginning of the disease, but later on she would go through periods of intense anxiety. She would pace through the house she had lived in most of her life crying uneasily that she wanted to go home. Or she would leave home and wander away if she were unattended for a short time.
Hoping to please her and put her mind at ease I would take her for a drive, visiting sites where she had lived as a child. In the yard of the hillside house in Shipman I sat in the car and admired the view of the old oaks and long green lawn. I pictured my mother there was a little girl playing with the pet lamb she had been so fond of. I looked to her for some response. She shook her head and said, “I want to go home.”
Over the years I have decided that what my mother was calling home was not a place, but a time. I suspect it was a time when she was much younger, when her children were still underfoot, when her husband was still vigorous and attentive.
Watching my mother's suffering set me wondering where I would have gone in mind if someday I couldn’t find home and wanted to go there. In this family we tend to be long-lived and we grow fuzzy (糊涂的) minded as the years go by. At eighty I have already noticed some alarming symptoms. My doctor says the forgetfulness is only natural and that it comes with age. Still the fear of Alzheimer's is haunting there. Someday if and when I become even more cloudy minded than I am now, unable to drive and unable to tell you where "home" is, my dear son, I expect I will ask you to take me home, I know you will do your best to find the place I need to be. I leave these notes for your guidance.What's the main idea of the first two paragraphs?

“Few things help an individual more than to place responsibility upon him，and let him know that you trust him.” These words are from the black American educator，Booker Washington. He was saying that，“If you want people to grow up，you have to stop treating them like children.”
In America，families are close but children are encouraged to be independent，to make their own decisions，even at a very early age. It’s not unusual for a child of seven to be given an allowance(津贴)every week. The child is encouraged to save some of the money but he or she can spend it on whatever they choose，for example，buying clothes，school supplies or CDs. Some teenagers even have their own credit cards! That’s a big responsibility since even adults are tempted to overspend when they have credit cards.
From an early age，American children are asked for their opinions and they are included in family decision making. At the dinner table，teenagers will be listened to on any topic，from politics to buying a new family car or where the family will go on vacation. In this way, teenagers are getting practice in becoming individuals：they are learning how to stand on their own two feet.
Many Chinese young people are becoming almost as interested as American teens in searching for independence. They want to express those qualities that make them unique human beings. You can see this in the way they dress, the music they listen to and the friends they choose. “Super Girl” Li Yuchun caught the imagination of Chinese teenagers on the “Super Girl” television contest. She was not the traditional “nice，young Chinese girl”. With her short，spiky hair and boy-like clothes, she was telling everyone that she was different. She had the courage to be her own person and to stand on her own two feet...and she won!
There is an old saying，“Everyone should carefully observe which way his heart draws him and then choose that way with all his strength.” If you do this, step by step, over a period of time, you may find that you have become the person you always wanted to be.A child of seven is given an allowance so that he can______.
| A．be accepted as a popular guy | B．learn to decide how to use money |
| C．overspend money without care | D．have school supplies of his own |
The author implies that many Chinese children________.
| A．are more independent than Americans |
| B．should become interested in America |
| C．are happy with their present situation |
| D．are not satisfied to be nice, quiet ones |
The main idea of the last paragraph is________.
| A．that we should do things step by step |
| B．why we should understand our desires |
| C．what we should plan for our own life |
| D．how we can manage to realize our dreams |
