Suppose you broke a cup or a bowl by accident, how would you deal with the brokenpieces? One day, Alice was washing (dish)．Suddenlyshe broke a beautiful plate (care)．Onhearing the sound, her father ran out of the study at once to see his daughterwas hurt. his relief, she was fine, so the father comforted her and toldher just to throw the broken pieces directly into the dustbin.

However,Alice said nothing.She picked up the pieces on the floor one by one.She evenlooked everywhere to make sure there were no pieces (leave)．Then Alice asked her father for someold newspapers and plastic bag.

           The father felt confused.He wondered what she was going to do.After Alice(wrap) the broken pieces with newspapers, she put (they) into theplastic bag, together with a card (say) “ Danger! Broken plate！” Finally, she placed the plastic baginto the dustbin.Not until then did the father realize how (consider) hisdaughter was.He learned a lesson from her!

        Carrots are easy to raise and easy to harvest. They taste good. .

        When people think of carrots, they usually picture in their mind a vegetable that islong, thin and orange. And not all carrots are orange. For example, Paris Market carrots are about five centimeters around. Rome carrots are thin andabout twenty－five centimeters long. And Belgian White carrots are, as their name suggests, white.

        For the best results, carrots should be grown in sandy soil that does not hold water for a long time. The soil also should have no rocks. To prepare your garden for carrots, dig up the soil, loosen it and turn it over. Then, mix insome plant material or animal fertilizer (肥料)．

Experts say warm days, cool nights and a medium soil temperature are the best conditions for growing carrots that taste great.

Carrots need time to develop their full sugar content. This gives them their sweetness if you wait too long to pull them from the ground. Usually, the brighter the color, the better the taste.

If the winter is not cold enough to freeze the ground, you can grow and harvest carrots the same way as during the summer months. If the ground does freeze,simply cover your carrot garden with a thick layer of leaves or straw. Thiswill prevent the ground from freezing.

a．But carrots come in many differentsizes and shapes.

b．They are economic crops.

c．The best time for planting carrots isduring the winter months.

d．Weather, soil conditions and age willaffect the way carrots taste.

e．The best way to judge if a carrot isready to be harvested is by its color.

f．And they contain a lot of carotene (胡萝卜素), which the body make into vitamin A.

g．Many people do not know that carrotscan be grown during the winter months.

       A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high－tech systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.

    “It's extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components (元件), ” said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go－ahead to start piecing together the components. “The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own，” he said.

       They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it' s connected to，” said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.

        While this first robotic flyer is linked to a small, off－board power source, the goal is eventually to equip it with a built－in power source, so that it might someday perform data－gathering work at rescue sites, in farmers' fields or on the battlefield. “Basically it should be able to take off, land and fly around，” he said.

        Wood says the design offers a new way to study flight mechanics and control at insect－scale. Yet, the power, sensing and computation technologies on board could have much broader applications. “You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead，” he said. “So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day－to－day basis.”

       When it comes to medical care, many patients and doctors believe “more is better.” But what they do not realize is that overtreatment—too many scans, too many blood tests, too many procedures—may bring harm. Sometimes a test leads you down a path to more and more testing, some of which may be invasive, or to treatment for things that should be left alone.

       Terrence Power, for example, complained that after his wife learned she had Wegener's disease, an uncommon disorder of the immune system, they found it difficult to refuse testing recommended by her doctor. The doctor insisted on office visits every three weeks, even when she was feeling well. He frequently ordered blood tests and X－rays, and repeatedly referred her to specialists for even minor complaints. Even when tests came back negative, more were ordered, and she was hospitalized as prevention when she developed a cold.   She had as many as 25 doctor visits during one six－month period. The couple was spending about $30,000 a year for her care.

       After several years of physical suffering and near financial ruin from the medical costs, the couple began questioning the treatment after discussing with other patients in online support groups. “It's a really hard thing to determine when they've crossed the line，” Mr. Power said. “You think she's getting the best care in the world, but after a while you start to wonder: What is the purpose？” Mr. Power then spoke with his own primary care doctor, who advised him to find a new specialist to oversee Mrs. Power's care. Under the new doctor's care, the regular testing stopped and Mrs. Power's condition stabilized. Now she sees the doctor only four or five times a year.

        Anyone who is afraid of failure and afraid to face challenges will never taste success, so said our professor in marketing. I laughed it off at that time, but got frightened when it actually happened in my life.

        I landed in a small city in the Middle East to set up a firm, a world－class car rental firm. Having decided on the project, I earnestly settled in preparation. With a positive mind, I told myself nothing should stop me now, and was more than keen to make it a success.

        However, the least expected thing happened. Iraq invaded Kuwait. Tension ran high in the region. Eventually the war broke out, and many people fled the country, leaving my firm in deep trouble.

       As usual, “things become difficult, and every effort seems to bring disappointment, it can be tempting to lower your expectations or even water_down your goals and ambitions.” I was no exception. I thought of running away. I remembered the words of Thomas Edison, “Many of life's failures are people who did not realize how close they were to succeed when they gave up.”

       I decided to hang on, telling myself, “I am not afraid of challenges and obstacles.” I stayed on through months of uncertainty and insecurity. Finances ran low, and banks could not wait to get their dues. To add to all this, the banks even threatened to take all my vehicles. I felt I made a wrong decision to move there. I was now ready to face failure.

      I was living against all hopes, believing that something good would happen. After 2 months the war ended. My persistence paid off: people started flooding back and the car bookings picked up, five times over.

      Success comes to the one who dares, even after failure, to think positively and look forward confidently. After all, it is only the experience that makes a man tough. Failure does not mean you will never make it. It means that it will take a little longer. It provides us with a learning experience.

      In my mind. Lance Armstrong is a real hero.He has 1 so many things and inspired so many people.

        He2 a life－threatening disease, and has lived a very complete life, 3 giving so much toothers.

Heis a great teammate and leader.He 4 his winnings from races to his5. Armstrong knew he could win only with their help.Even though hehas retired, he still helps direct the6.Many people admire him 7what he has achieved. Lance Armstrong was 8 with cancer at 25 and didn't just survive but went on to again win the 9cycling race inthe world, the Tour de France.He has raised money for cancer patients.He also10 the Lance Armstrong Foundation and has helped the Make－A－WishFoundation.

Obtaining fresh water from icebergs

        The idea of getting fresh water fromicebergs that are moved to populated areas or places was once treated as ajoke.Recently, scientists have warned that the human race will outgrow itsfresh water supply faster than it runs out of food.

Glaciers are a possible source offresh water that has been overlooked until recently.It contains fresh water so much thatit could sustain all the rivers of the world for 1，000 years.

Huge glaciers that stretch over theshallow continental shelf give birth to icebergs throughout the year.However, they are formed entirely onland, breaking off when glaciers spread over the sea.As they drift away fromthe polar region, icebergs sometimes move mysteriously in a direction oppositeto the wind.Because they melt more slowly than smaller pieces of ice, icebergshave been known to drift as far north as 35 degrees south of the equator in theAtlantic Ocean.

The difficulty exists such as itsrapid melting in warmer climates.

a．Icebergsare not like sea ice, which is formed when the sea itself freezes.

b．Nowit is being considered quite serious by many nations.

c.7，659 trillion metric tons of ice isfloating on the sea every year.

d．Butthe water they could provide would be far cheaper than that produced.

e．Tomove them to try parts of the world would not be too difficult.

f．Itis not a dream to get water from Icebergs.

g．Three­quartersof the Earth's fresh water supply is still tied up in glacial ice.

          The largest land animal remaining on the earth, the African elephant, is of much importance to the African ecosystem. Unlike other animals, the African elephant is to a great extent the builder of its environment. As a giant planteater,  it  significantly  shapes  the  forest－and－savanna surroundings in which it lives, therefore deciding the conditions of existence for millions of other animals that live in its habitat.

         It is the elephant's great desire for food that makes it both a disturber of the environment and an important builder of habitat. In its continuous search for the 300 pounds of plants it must have every day, it kills small trees and bushes, as well as pulls branches off big trees.   This results in numerous open spaces in not only deep tropical forests but also the woodlands that cover part of the African savannas. In these open spaces, there are numerous plants in various stages of growth, which attract a variety of other plant－eaters.

        Take the rain forests for example. In their natural states, the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor. By pulling down trees and eating plants, elephants create open spaces, allowing new plants to grow on the forest floor. In such situations, the forests become suitable for large－hoofed plant－eaters to move around and for small－sized plant－eaters to obtain their food as well.

         Scientists are worried now that the African elephant has become an endangered species. If the elephant dies out, scientists say, many other animals will also disappear from vast areas of forests and savannas, greatly changing and worsening the whole ecosystem.
