    What is color? Why do some of the things around us look red, some green, others blue?
    Colors are really made by deflected (反射) light. We see color because most of the things reflect light. In the same way, if something is green, it reflects most of the green light. If something reflects all light, it is white. If it doesn’t reflect any light, it is black.
    Some of the light is reflected and some is taken in (吸引) and turned into (变成) heat (热能).The darker the color is, the less light is reflected, the more light is taken in. So dark-colored clothes are warmer in the sun than light-colored clothes.
    小题1:When something reflects light, we can _____.
    A．see its colorB．see its heatC．not see its colorD．see nothing
    小题2:Something looks white because it reflects _____.
    A．some lightB．no lightC．all lightD．most light
    小题3:the dark-colored clothes are warm because ____ is taken in.
    A．more lightB．less lightC．more colorD．less color
    小题4:In summer ______ make people feel cool.
    A．dark-colored clothesB．red-colored clothes
    C．green-colored clothesD．light-colored clothes
    小题5:What’s the best title(标题)of this passage( 短文 )?

    We talk every day. When we have good news, we like to share it with our good friends and when something terrible happens, we tell it to others soon. But can you imagine that a tree can talk and share news too ? Of course, no tree moves lips and says words just as people do. Strange as it may sound, though, some trees do manage to communicate with each other.
    Willow (柳树) trees are the best-known of these trees. When insects begin nibbling (叮咬) a willow tree, the tree sends out a special smell at once. This smell tells the other willows that harmful insects are coming near. All of them quickly make a chemical (化学物质) in their leaves. This chemical is bad to the insects. The insects do not like it and they fly away soon. In this way, the willow trees protect themselves from the insects.
    The next time when you take a walk in the woods, maybe the trees are “talking” to each other quietly. And when someone says that trees cannot “talk”, please tell them that even trees give messages to each other, too.
    小题1:Willow trees send messages with_____________.
    A．wordsB．movementsC．smellsD．sounds
    小题2:The underlined word “lips” in the first paragraph means _____________.
    A．树干B．嘴唇C．枝条D．手势
    小题3:The passage tells us that some of the trees can _____________.
    A．speak just as people doB．tell stories to others
    C．communicate with each otherD．kill insects in the woods
    小题4:According to the passage, the right order of the following is _____________.
    a.  The willow tree gives out a smell.
    b.  The willow trees make a chemical in their leaves.
    c.  Insects fly away because of the chemical.
    d.  Insects begin nibbling a willow tree.
    A． d---a---b---cB． d---b---a---c
    C． a---b---c---dD． d---c---b---a

    Happiness is for everyone. You don’t need to care about those people who have beautiful houses with large gardens and swimming pools or those who have nice cars and a lot of money and so on. Why? Because those who have big houses may often feel lonely and those who have cars may want to walk on the country roads at their free time.
    In fact, happiness is always around you if you put your heart into it. When you are in trouble at school, your friends will help you; when you study hard at your lessons, your parents are always taking good care of your life and your health; when you get success, your friends will say congratulations to you; when you do something wrong, people around you will help you to correct it. And when you do something good to others, you will feel happy, too. All these are your happiness. If you notice a bit of them, you can see that happiness is always around you.
    Happiness is not the same as money. It is a feeling of your heart. When you are poor, you can also say you are very happy, because you have something else that can’t be bought with money. When you meet with difficulties, you can say loudly you are very happy, because you have more chances to challenge(向…挑战)yourself. So you can not always say you are poor and you have bad luck. As the saying goes, life is like a revolving(旋转)door. When it closes, it also opens. If you take every chance you get, you can be a happy and lucky person.
    小题1:Those who have big houses may often feel         .
    A．happyB．lonelyC．freeD．excited
    小题2:When you fall down in a PE class, both your teacher and your classmates will     .
    A．laugh at youB．play jokes on you
    C．quarrel with youD．help you up
    小题3:What will your friends say to you when you make great progress?
    A．Oh, so do IB．Congratulations
    C．Good luckD．It’s just so-so
    小题4: Which idea is NOT right according to the passage?
    A．People who have cars would never like to walk in the open air
    B．You can get help from others when you make mistakes
    C．You can still be a happy person even if you have little money
    D．Happiness is always around you though difficulties come towards you
    小题5: Which of the following is this passage about?

    Three kids have been learning chemistry for only a few months. But they have already begun to challenge (挑战) a world famous scientist!
    Li Weichi, Huang Runling, and Xiao Yan are from Zhongshan Huaqiao Middle School in Guangdong. They have just found a red cabbage that could be a new kind of acid-base indicator (酸碱指示剂). They want it to take the place of litmus (石蕊) paper.
    "We’ve learnt to think of and ask questions about life by ourselves," said Li, "We work well with each other."
    British scientist Robert Boyle discovered the use of litmus paper over 300 years ago. Now it is used widely in experiments all over the world.

    "It’s our first scientific journey, Huang said, "But it makes me want to try harder."

    Smoking in indoor public places including public working places, public transport vehicles and some other special outdoor working places has been banned(禁止)in China since January 2011.Let’s look at the following advantages of banning smoking.
    First, banning smoking will not only help in saving smokers from health problems and diseases, but will also be good for passive(被动)smokers. When the smoker is smoking in a restaurant, the people around him are sure to breathe in the smoke and suffer from the diseases an active smoker gets. If smoking is banned, spread of these diseases can be controlled.
    Next, banning smoking will put stress on smokers to give up.  Since a smoker is prevented from smoking, he will learn how to live without smoking for long hours. When a smoker doesn’t smell or see anybody around him smoking, it might reduce his wish to smoke too. As a result, people have to give up smoking.
    Smoking in public places influences non-smokers to start smoking, especially adolescents. When teens see people around them smoking, they will follow them easily. Thus the number of teen smokers will increase. Also asthma(哮喘)and other problems are often seen in children living around smokers. So if it is banned, these places will become safe for children and teenagers.
    Looking from the economic point of view, smoking should be banned to increase work productivity(生产率).Employees(雇员)who smoke usually take breaks to smoke while working. So the number of  hours they put in their work is smaller.
    If you see from the environment point of view, smoking should be banned. Smoking causes air pollution. If it is banned, it will help keep the environment from getting worse.
    小题1:________doesn’t belong to a non-smoking place.
    A．A fieldB．A hospitalC．A libraryD．A restaurant
    小题2:The second paragraph mainly wants to tell us ______.
    A．banning smoking is good for restaurants
    B．banning smoking is good for non-smokers
    C．banning smoking is good for spread of diseases
    D．banning smoking is good for active smokers and passive smokers
    小题3:How many advantages of banning smoking are mentioned in this passage?
    A．Two.B．Four.C．Five.D．Six.
    小题4:According to the text, the underlined word “adolescents” means ______.
    A．menB．womenC．adultsD．teenagers
    小题5:Which of the following statements in NOT true?
    A．If smoking is banned, work productivity will increase.
    B．If smoking is banned, the number of teen smokers will be larger.
    C．If smoking is banned, it will make the environment become better.
    D．If smoking is banned, smokers will learn how to live without smoking.
