    A green house is a building made of glass which is used for keeping warm when the outside temperature is low. In a similar way there are several gases in the atmosphere (mixture of gases that surround the earth) which trap the heat produced by the sun and prevent it from escaping. These gases are known as “greenhouse gases”. and the way in which they trap heat in the atmosphere is called the “greenhouse effect”. This is not simply air pollution. Most of the main greenhouse gases exist naturally in small amounts in our atmosphere, and without them the earth would be 30 degrees colder and human life would not exist. In other words, the greenhouse effect is a natural course which is to some degree helpful to us.
    The problem is that in the last century and a half, we have been putting too many of these gases into the earth’s atmosphere by burning large quantities of coal and oil and by cutting down forest. The rapid increase in greenhouse gases is making the world warmer. The world’s temperature has already gone up by half a degree this century, and the sea level has risen by 10 centimetres. If the amount of carbon dioxide in the atmosphere doubles, there will probably be a rise in the earth’s temperature of between I and 4℃;. This may seem a small increase, but it would be enough to cause major changes in geography and agriculture. Large areas of the world would be flooded, and some areas would become dry and unable to produce crops. It is important, too, to consider that there may be a delay of about 30 years in the greenhouse effect. This means that we are probably experiencing only now the effect of the gases put into the atmosphere before the 1960s. Since then, our use of these gases has greatly increased.
    小题1: According to the passage, we can know “greenhouse effect” means_______.  
    A．the way in which gases are used for keeping plants warm
    B．a natural course that is to a certain degree useful to us
    C．the way “greenhouse gases” trap heat on the earth
    D．the whole course in which greenhouse gases prevent heat
    小题2: If there were no greenhouse effect,_______.
    A．all plants would not grow on our planetB．soil would reduce the temperature by 30 degrees
    C．man would breathe the cleaner airD．people couldn’t live in the earth
    小题3: Which of the following is not true?
    A．Burning too much coal and oil produces lots of greenhouse gases.
    B．It has become warm on the earth now than in the past.
    C．Gases put into the atmosphere now will affect the earth years later.
    D．The temperature in a greenhouse is as high as that in the atmosphere.
    小题4: Suppose the earth’s temperature rose by 3 degrees, _______. 
    A．great harm will be done to mankindB．the sea level would go up by 10 centimeters
    C．all the land in the world would be floodedD．crops would be unable to grow on the earth
    小题5: This passage mainly deals with ________.
    A．the concept (概念) and the harm of the greenhouseB．the relation between greenhouse gases and man
    C．the concept and change of greenhouse effectD．the effect of the rise of the earth’s temperature

    There are two kinds of physical activity which require special training. The first demands exact, careful movements of the muscles（肌肉）.This kind of activity must be strictly controlled because even a slight movement in the wrong direction will lead to a mistake. To type quickly, for example, a person needs training; the slightest movement of a finger in the wrong direction may cause a spelling mistake. A dancer who has to dance on the point of her shoes or turn around on one foot must be trained for a long period of time before she can sense her own center and balance herself. You may have seen a girl walking on a rope across an empty space, which, too, requires a lot of practice.
    The second kind of physical activity needs greater strength or extra effort. Most of us get tired if we try to run half a mile without stopping, but a specially-trained person can do this without much effort. Three years ago, some scientists carried out experiments, which produced meaningful and unexpected results. They wanted to find out whether a certain amount of physical exercise would injure those suffering from heart problems. They selected some male patients and trained them in continuous bicycle riding. They were surprised to find that the harmful effect of a given amount of physical effort was actually less on the hearts of these trained patients than on those of the patients who were not similarly trained. This is important because it shows that regular physical exercise enables us to make better use of the oxygen we breathe in and that this training, in fact, reduces the amount of work our hearts do. Many tasks which are hard for untrained people are not hard at all for trained people.
    小题1:.  The first kind of physical activity must be strictly controlled because ______.
    A．a mistake in the wrong direction is dangerous to the fingers
    B．a wrong movement in a direction will cause no mistakes
    C．a movement in the wrong direction will cause a mistake
    D．a slight movement of a finger will lead to a mistake
    小题2:.            
    What must a dancer do before she can balance herself?
    A．she must dance on the point of her shoesB．she must receive long-time training
    C．she must turn around on one footD．she must perform again and again
    小题3:.            
    The experiments done by some scientists showed that __________.
    A．some male patients were asked to ride bicycles regularly in the experimentsB．the physical exercise had more harmful effect on the hearts of the untrained patients
    C．the physical exercise was harmless to the male patients with heart trouble
    D．the physical exercise could be helpful for the patients to take in more oxygen
    小题4:. What would be the best title for this text?
    A．Training Our BodiesB．Physical Activities
    C．Movement TrainingD．Extra Body Effort

    Terraforming (Earth-forming) other planets, also known as planetary engineering (行星工程), seems like a task still centuries away for mankind to accomplish. However, it is a vigorous topic that attracts both popular and scientific interest. Why should the possibility of terraforming other planets be studied when it may be centuries before we know enough to even decide if it’s a good idea?
    Mankind is getting more and more hard facts about other planets. The atmosphere of Venus has been explored; robots have surveyed the surface of Mars; Mercury, Jupiter and Saturn have been studied by spacecraft. Speculations have been answered; new questions have been raised, and enough hard data is right now becoming available to allow us to make the first attempt of planetary engineering.
    In the past, people with excellent ideas about terraforming have kept them to themselves, or buried them in a desk drawer because they did not realize that anyone else was interested. But now, a wide circle of people has begun to do this kind of work. For instance, NASA funded a project on transforming Mars.
    There are several strong reasons which demand that the possibilities of terraforming be studied carefully. First, it’s an exciting idea of a possible future for human beings. Such thinking has a valuable role in providing options for our future directions. Secondly, the techniques of terraforming will also help contemporary technologies in weather and climate control. Thirdly, such study may assist us in detecting any possible existence of extraterrestrial intelligence (SETI, The Search for Extraterrestrial Intelligence, 地外文明搜索) and alien (异己的) civilizations on other planets.
    Though the mission is far beyond our reach at the moment, we should at least keep our options open. Through debate and study on this subject, the possibility of rebuilding other planets to make them suitable homes for people may come true some day in the future.
    小题1:.
    . According to the context, what’s the meaning of the word “speculation” in paragraph 2?
    A．The act of discussing something with a group of people.
    B．The act of studying and researching.
    C．The act of guessing without knowing all the facts about something.
    D．The acting of writing letters to a certain organization.
    小题2:.
    Why did people keep the idea of terraforming to themselves in the past?
    A．They thought no one else would show interest in the idea.
    B．They gradually came to find the idea crazy.
    C．They thought the idea would never come true.
    D．They had few resources for further study on this topic.
    小题3:.
    . Which is NOT the reason to support the study of terraforming?
    A．Even if we don’t succeed in terraforming, such study may help us to better understand technologies such as climate and weather control.
    B．Such study may explore a new direction of development for human beings.
    C．Such study may enable us to find the lives on other planets.
    D．As the resources on Earth are being drained, it’s very urgent to study how to migrate (迁移) to other planets。
    小题4:.
    What’s the main idea of the article?
    A．It’s highly possible that terraforming other planets will come true so we should increase investing in this program.
    B．Even if the idea of terraforming other planets may take centuries to realize, we have many reasons to support such studies.
    C．Terraforming other planets is the best option for human being’s future.
    D．More and more people are taking planetary engineering as their occupation.

    Next Hot Language to Study: Chinese
    The fourth-graders at Chicago’s McCormick Primary School are unaware of the difficulty in learning Chinese. For most, who speak Spanish at home, it’s becoming their third language. They’ve been learning and using Chinese words since kindergarten, and it’s now second nature to give a hearty “ni hao” when strangers enter the classroom.
    The classroom scene at McCormick is unusual, but it may soon be a common fixture(固定物) in American schools, where Chinese is rapidly becoming the hot new language. Government officials have long wanted more focus on security—useful languages like Chinese, and pressure from them—as well as from business leaders, politicians, and parents—has driven a quick growth in the number of programs.
    Chicago itself is home to the largest effort to include Chinese in US public schools. The program here has grown to include 3,000 students in 20 schools, with more schools on a waiting list. Programs have also spread to places like Houston, Los Angeles, New York City, and North Carolina. It’s true that the number of students learning Chinese is tiny compared with how many study Spanish or French.
    Advocates (提倡者，拥护者) see knowledge of the Chinese language and culture as a help in a global economy where China is growing in importance. “This is an interesting way to begin to engage with the world’s next superpower,” says Michael Levine, director of education at the Asia Society, which has started five new public high schools that offer Chinese. “Globalization（全球化) has already changed the arrangements in terms of how children today are going to need to think about their careers… The question is, when not whether, the schools are going to adjust.”
    In Chicago, the trend extends beyond schools with high numbers of Asian students. “The fact that my students are 98% low income and 99% Latino(拉丁美洲人) and they are succeeding in this, tells me everyone should have a try at learning languages,” says Virginia Rivera, principal at McCormick.“We want to give our young people opportunities to advance… and Chinese is a great opportunity to survive in today’s economy,” says Richard M. Daley, Mayor of Chicago.
    小题1:The first paragraph is mainly written to _______.
    A．show the importance of Chinese learning
    B．introduce the topic to be followed
    C．advise primary schools to teach Chinese
    D．prove it’s easy for children to learn language
    小题2: How many languages are mentioned in this passage?
    A．Six.B．Two.
    C．Three.D．Four.
    小题3: In the last paragraph, the underlined word “this ”probably refers to _____.
    A．the competition between Latino and Asian students
    B．the global economy
    C．the interesting way to engage with China
    D．the Chinese learning
    小题4: What CANNOT be learned from this passage?
    A．Most students at McCormick can speak three languages.
    B．Chinese is gaining its popularity in all schools in Chicago.
    C．French has far more speakers than Chinese does in Chicago.
    D．Globalization in a way makes it necessary to learn Chinese.
    小题5: Which of the following is mainly about in this passage?
    A．The Chinese learning in Chicago.
    B．The ways to learn Chinese.
    C．McCormick Primary School.
    D．Globalization and Chinese learning.

    Thanks to the huge success of Harry Potter, many teenagers dream about living in an ancient castle. These dreams may include beautiful silk dresses, delicious food, servants and of course, magic. However, real life in an English castle was not easy. With thick stonewalls and high towers, castles were built for defence(防御). So they were not good places to live in. In medieval times, castles must have been noisy and smelly places. Horses, cattle, chickens and sheep walked free, blacksmiths did ironwork, soldiers practised sword (剑) fights, and children of all ages played around them. Castles did not have central heating; the only heat came from the fireplace. Even in summer the castle was cool. People living in the castles had to use blankets to keep warm while at work.
    Life during the Middle Ages began at sunrise. Servants lit the fire, swept the floor and cooked the morning meal. The mid-morning meal was the main meal of the day and often included three or four courses (一道菜). After dinner, everyone continued his or her work. The owner of the castle, the lord, sometimes took his guests hunting or shooting. His wife, the lady, spent much of the day watching the maids (女仆) work, as well as people working in the kitchen. She also kept an eye on the weavers and embroiderers who made clothes for the family. Supper was simple and eaten late, just before bedtime.
    You may find some old magic books in a castle as Harry Potter once did. Read them before you go to bed, because when you fall asleep the magic of castle life may appear before your eyes.
    小题1: For what purpose were the castles built in England?
    A．To defend the city or country against enemies.
    B．To provide a working place for blacksmiths.
    C．To raise poultry (家禽) and livestock (家畜).
    D．To provide a place for teenagers to learn magic.
    小题2: Why were the ancient castles noisy?
    A．Because soldiers practiced sword fights there.
    B．Because blacksmiths did ironwork there.
    C．Because children of all ages played around them.
    D．All of the above.
    小题3: Which of the following about family life in castles is true according to the passage?
    A．The servants in castles lived an easy life.
    B．The wife spent much of the day at home.
    C．Supper was eaten before sunset.
    D．Dinner was eaten in the middle of the day.
    小题4:The main idea of this passage is ______.
    A．castles were not good places to live in
    B．castles in novels are different from those in history
    C．Harry Potter's story in a castle affected people
    D．what real life was like in an ancient castle

    The world is filled with many interesting sounds. Some are very pleasant to hear; others are unpleasant to our ears. In a day, you probably hear hundreds of different sounds.
    All sounds are different. Some may be soft; others may be loud. Some sounds are high; others are low.
    Some sounds are useful. Without sound we cannot talk or listen to one another. The ringing alarm clock (闹钟)makes people wake up. The hooting of a horn (喇叭声) on the road warns careless people of danger.
    We make sounds by making things move to and fro(来回地). This to-and-fro movement is called vibration (振动). It means moving up and down or forwards(向前地) and backwards(向后的) very fast. This makes sound waves(波).
    We can make sounds in many ways, for example, by shouting, clapping our hands and striking the table. We can make sounds only by making things vibrate. We can talk because we can make our vocal cords (声带) vibrate. Our vocal cords are in a sound box or voice box. Two vocal cords vibrate when our lungs(肺) force the air through them.
    小题1:We can make sounds ______.
    A．by making things still
    B．by making things vibrate
    C．by making things jump up and down
    D．by changing the positions of things
    小题2: Some sounds are useful because ______.
    A．they can wake people up
    B．they can warn people to be careful when they are crossing the road
    C．they make it possible for people to talk or listen to each other
    D．all of the above
    小题3:When the air is through our vocal cords, it can make them ______.
    A．vibrateB．breathe the air
    C．talk to each otherD．move forward and backward
    小题4:Sounds are different because ______.
    A．different sounds have different vibrations
    B．different sounds have different sound waves
    C．different sounds have different vocal cords
    D．both A and B

    The American book Who Moved My Cheese has been a bestseller all over the world. It teaches people how to face changes in their lives. Now its author Spence Johnson has written a book just for teens. The book tells us that when facing change in our lives, like a new school or new friends, don't be afraid. Instead, use this change to make a better life. The book gives an example of a change at school. A school is changing from having two terms to three terms because there are too many students.
    Several teens are talking about this. Most of them are unhappy and worried. But Chris is not. He laughs and tells a story about two mice, two “little people” and some cheese.
    The four are in a maze looking for the cheese. Here, cheese means something important in life, like moving to a new class or getting into college. But they find the cheese is gone. The mice realize that they can’t change what has happened and have to find more cheese. This means finding different dreams. The little people, however, can’t do this. They are afraid of change so they find no cheese.
    After Chris finishes the story, the friends understand one thing: to get more cheese, move in a new direction quickly. His friends understand how this can be used in the changes all teens face, such as doing well at school or having good relationships or just feeling good about yourself.
    小题1:The book Who Moved My Cheese is __________.

    Early this month, on the Egyptian-Israeli border not far from her hometown, a series of bombings killed 35 people and injured more than 160. Despite the attack, life quickly returned to normal. Living under the threat of attack is normal here.
    Israel teenagers’ interests are not very different from others’. “Low-cut jeans（低腰牛仔裤）and miniskirts are very in,”said Hinanit, an 18-year-old teenager.
    “You cannot let the fighting control what you do and don’t do. Of course I am scared sometimes, but I still go out and have fun. Yon always have to be careful, and things are probably more dangerous now, but I still love Israel. It is my home, and I would not leave it for anything!” Cohen said.
    Meanwhile, on the other side of the Gaza Strip, a Palestinian boy named Bilal lies in a hospital bed, with his friends round, praying for his life. He has been in a coma（昏迷）since Israeli soldiers shot him on his way to school last month. In this recent military action, Israeli soldiers have killed at least 83 Palestinians, including 24 children.
    Palestinian children lead a dangerous life under the watchful eyes of Israeli soldiers. Israel presents them as terrorists（恐怖分子）and faceless stone throwers. Many Palestinian children have been driven away from homes into crowded and hungry refugee camps with their families. “Even if we are surrounded by Israeli soldiers and have no food, we will stand and defend our country,” said Fatima Al-Aidi，a 13-year-old teenager, who lost a friend in Israel’s recent attack. “I hope to carry a lot of weapons and take my revenge（报复）one day. I hope the day comes when the enemy leaves Palestine.”
    小题1:The underlined sentence “Despite the attack, life quickly returned to normal” means “     ”.
    A．Life has returned to normal as a result of the attack
    B．Life remains normal even if there was an attack
    C．Life has returned to normal, although there was an attack
    D．If there is not the attack, life will return to normal
    小题2:Cohen’s words suggests that she        .
    A．is living in horrorB．is peace-loving
    C．wants to join the armyD．doesn’t let fighting change her life
    小题3:How does Israel think of Palestinian children? They are______
    A．lovelyB．smartC．friendlyD．dangerous
    小题4:What can we learn from what Fatima Al-Aidi said?
    A．He was in poor health.
    B．he hated Israeli soldiers.
    C．He was eager to invent some other weapons to attack Israel.
    D．He wishes more help to be given.
