    Look at the center circles of Diagram (图) A and Diagram B.  Which of the centre circles looks larger? 
    Take a first look and you probably think that the centre circle in Diagram A is smaller than that in Diagram B. In fact , they are exactly the same size.
    Then look at the picture on the right. What do you see? A vase ? Or two faces? Does the picture change quickly from one to the other again and again? Maybe or maybe not, but you can never see them at the same time. 
    "What's happening? Is something wrong with my eyes?" You may wonder at what you see. Don't worry. Here is how it goes:
    When we look at things, our eyes send messages to our brains and then our brains interpret (解读) the information. However, sometimes our brains interpret the received information in a wrong way. It seems that our eyes are playing a joke on us. This often happens and we call it "Visual illusion" (视觉错误). 
    Movie makers often make use of illusions. They make the objects around actors much smaller or bigger than usual. This makes us believe that the actors are much larger or smaller than they usually are. The movies Jurassic Park and Honey I shrunk the kids just make use of illusions.
    小题1:The centre circle in Diagram A looks smaller than that in Diagram B. That's because           .
    A. something is wrong with our eyes
    B. the two circles are not the same size
    C. our brains interpret the information in a wrong way
    D. the two pictures change quickly from one to the other
    小题2:What's the right order according to the passage?
    a. We look at things with our eyes.              b. Our brains interpret the messages.

    A．help the actors look better
    B．make the actors much braver
    C．help the actors become stronger
    D．make the actors seem different in size
    小题4:In the picture on the right, it seems that Line AB is shorter than Line CD, but in fact Line AB is as long as Line CD. Which paragraph can explain what has happened to our eyes?___________
       
    A.The second one.
    B.The third one.
    C.The fifth one.
    D.The sixth one.

    In the 13th century, the Italian traveler, Marco polo , traveled a long way to China , During his stay in China , he saw many wonderful things . One of the things he discovered was that the Chinese used paper money . In western countries , people did not use paper money until the 15th century . However , people in China began to use paper money in the 7th century .
    A Chinese man called CaiLun invented paper almost 2000 years ago. He made it from wood . He took the wood from trees and made it into paper . He then put these pieces of paper together and made them into a book .
    Now paper still comes from trees . We use a lot of paper every day ! If we keep on wasting so much paper , there will not be any trees on the earth . If there are no trees , there will be no paper . Every day , people throw away about 2800 tons (吨) of paper in our city . It takes 17 trees to make one ton of paper . This means that we are cutting nearly 48000 trees every day . Since it takes more than 10 years for a tree to grow , we must start using less paper now . If we don’t , we will not have enough time to grow more trees to take the place of those we use for paper .
    So how can we save paper ? We can use both sides of every piece of paper , especially when we are making notes .We can choose drinks in bottles instead of those in paper packets . We can also use cotton handkerchiefs (手帕) and not paper ones . When we go shopping , we can use fewer paper bags . If the shop assistant does give us a paper bag, we can save it and reuse it later .
    Everyone can help to save paper . If we all think carefully , we can help protect trees . But we should do it now , before it is too late .

    I know what you’re thinking: pizza? For breakfast? But the truth is that you can have last night’s leftovers in the a. m. if you want to.
    I know lots of women who skip (跳过) breakfast, and they have a lot of different excuses for doing it. Some say they don’t have time. Others think they’re “saving” calories, still others just don’t like breakfast food.
    But the bottom line is that eating in the morning is very important when you’re trying to lose weight. “Eating just about anything from 300 to 400 calories would be better than nothing at all,” says Katherine Brooking, R, D, who developed the super-easy eating plan for this year’s “SELF CHALLENGE”. And even pizza can be healthy if it’s loaded（装填） with vegetables, and you just eat one small piece.
    Breakfast is one meal I never miss, and the same goes for most weight loss success stories. Research shows that eating breakfast keeps you from overeating (吃得过多) later in the day. Researchers at the University of Southern California found that breakfast skippers have a bigger chance of getting weight than those who regularly have a morning meal.
    So eat something in the morning, anything. I know plenty of friends who end up having no breakfast altogether, and have just coffee or orange juice. I say, try heating up last night’s leftovers — it may sound crazy, but if it works for you, do it! I find if I tell myself, “You can always eat it tomorrow.” I put away the leftovers instead of eating more that night. Try it…you may save yourself some pre-bedtime calories. And watch your body get the fat-burning effects.
    小题1:The word “leftovers” in Paragraph 1 probably means_______.
    A．food left after a meal B．things left undone
    C．meals made of vegetablesD．pizza topped with fruit
    小题2:What can we infer from the text?
    A．Working women usually have breakfast in a hurry.
    B．Many people have wrong ideas about breakfast.
    C．There are some easy ways of losing weight.
    D．Eating vegetables helps save energy.
    小题3:According to the last paragraph, it is important to_______.
    A．be careful about what you eatB．eat calorie-controlled food
    C．heat up food before eating itD．eat something for breakfast
    小题4:The text is written mainly for those_______.
    A．who want to lose weightB．who go to work early
    C．who stay up lateD．who eat before sleep

    Saving water is an important part of going green. As water becomes less and polluted more, conservation (保护) becomes more and more important. The less water you use, the less wastewater will end up in our rivers and lakes. Wasting water means that more water needs to be treated and cleaned, a process that requires quite a lot of energy.
    As it is said above, cutting down on water usage is one of the most important things you can do for your local environment and the planet as a whole. That is why more green households are going blue: cutting down their water footprint by conserving and harvesting (收获) water.
    It may seem like a big concept, but going blue starts with small changes that everyone can make. Something as simple as turning off the tap while you brush your teeth can save a lot of water. Wash your fruits and vegetables in a bowl rather than under a tap to save even more. Make sure that the taps are fully turned off every time you step away from the sink or the shower — all those little drips can add up to a lot of water waste.
    Another way of reducing your water footprint is reducing your dependence on the main water supply. Rainwater harvesting can meet a lot of your home’s water needs. Many of us already practice rainwater harvesting in a small way. Collecting water from your gutters (檐沟) is a great way to keep your garden green without running the sprinkler (洒水器).
    小题1:The underlined word “green” means ______ in this passage.
    A．嫉妒B．环保C．未成熟的D．健康的
    小题2:According to the passage, which is NOT the reason that people should save water?
    A．Treating wastewater needs much energy.
    B．The water on the earth is becoming less and less.
    C．The water on the earth is becoming polluted more.
    D．Rainwater harvesting can meet a lot of your home’s water needs.
    小题3:According to the passage, all of these can be used to save water except ______.
    A．washing fruit and vegetables under a tap
    B．using a bowl to wash your fruit and vegetables
    C．making sure taps are fully turned off all the time
    D．turning off the tap every time after brushing your teeth
    小题4:Which of the following is the best title of this passage?
    A．Save Water by Turning off the Tap
    B．How to Treat and Clean Wastewater
    C．Keep Your Garden Green with Rainwater
    D．Save Water Starting with Small Changes
    小题5:From the passage, we can know that_____.
    A．we can get enough water by harvesting
    B．most people pay no attention to saving water
    C．we can practice rainwater harvesting in a small way
    D．harvesting water is more necessary than conserving it

    BEING an astronaut sounds cool, doesn't it? In space, they get to do some pretty amazing things, like floating in zero gravity(重力).
    However, there are also plenty of things that astronauts can't do because of their weightless environment, and that's very sad. What's worse, they can't even let their sadness show, because it's impossible to cry in zero gravity.
    Of course, astronauts can still produce tears. But crying is much more difficult in space, according to The Atlantic(大西洋月刊) in January. Without gravity, tears don't flow(流动) down out of the eyes like they do here on Earth. This means that when you cry in space, your tears have nowhere to go-they just stick(粘) to your eyes.
    In May 2011, astronaut Andrew Feustel experienced this during one of his spacewalks. "Tears," he said, "don't fall off of your eyes...They just kind of stay there."
    Besides making your vision(视线)unclear, this can also cause physical pain. Back on Earth, tears are supposed to bring comfort to the eyes. But that's not the case in space. The space environment dries out astronauts' eyes, and when tears suddenly wet the eyes, it can cause pain rather than comfort. "My right eye is stinging(刺痛) like crazy," Feustel told his teammate during the walk.
    Since gravity doesn't work in space, astronauts need some extra help to get rid of（除去） the tears. Feustel chose to rub his eyes against his helmet to wipe(擦) the tears away. Another choice is to just wait-"When the tears get big enough they simply break free of the eyes and float around," astronaut Ron Parise told The Atlantic.
    There are lots of small things-things like crying-that we are so used to on Earth. We usually take them for granted until they become a problem in a totally different environment, like space.  There, astronauts can't talk to each other directly. They also can't eat or drink in normal ways. They can't even burp (打嗝), because there is no gravity to hold the food down in their stomach. If they do burp, they just end up throwing up（呕吐）everything in their stomach, according to the UK National Space Center.
    Therefore, perhaps it's only space explorers who can honestly say: "Gravity, you're the best."
    小题1:From Paragraphs 2 and 3 , we can know that_______.
    A．astronauts are unable to feel sad in space
    B．astronauts produce fewer tears in space
    C．tears produced in space flow down more slowly
    D．tears produced in space don't flow downward
    小题2:What effect do tears have on astronauts?
    A．They cause physical pain.
    B．They bring comfort to them.
    C．They make their vision clearer.
    D．They float around and cause trouble.
    小题3:The underlined phrase "take them for granted" in paragraph 7 means _______.
    A．find them important
    B．consider them useless
    C．need them during an emergency
    D．fail to notice their presence(存在)
    小题4:The second-to-last paragraph (paragraph 7) is mainly about_______.
    A．suggestions of how astronauts can stay comfortable in space
    B．other basic things that are difficult to do in space
    C．why burping is impossible in space
    D．things human can't do without gravity

    Garden building is considered an important part of Chinese culture. Some people say that if you have never walked through a Chinese garden, you cannot say that you have really visited China.
    Traditional Chinese gardens are located(位于)in North China in such places as Beihai Park, the Summer Palace, the Forbidden City. In larger imperial gardens, the main buildings are connected by an imaginary（虚构的） line in the middle of the garden on the north-south axis(轴). Other features (特征)of imperial gardens are colored-paintings, man-made hills and lakes.
    Most private gardens are found in the south, especially in cities south of the Yangtze River. Private gardens were mostly built at one side or at the back of the houses. Around the beautiful scene are small open areas with beautiful shaped-doors through which visitors can enjoy the sights. They are open on all sides and are often near the water so that the whole scene can be enjoyed. Suzhou, known as the home of gardens, displays the most and the best Chinese traditional private gardens. Different parts of it are examples of the garden style of the Song, Yuan, Ming and Qing Dynasties.
    The landscape garden contains a number of pleasant natural scenes and some fairy tales. The ancient Chinese used to call the garden landscape “Jing” , which means “scene” in English. Good examples include the ten West Lake Scenes in Hangzhou, the twenty-four slim West Lake in Yangzhou and the eight Daming Lake Scenes in Jinan.
