    For a long time, humans have used technology (科技) to study the world around us, and Mars is the latest place we’re using machines to explore. Besides the earth, the “red planet” is seen, as the one place in our solar system most likely to have life.
    Early last month, the first American robot, Spirit, landed on Mars without any problem. Opportunity, the second robot, landed on the planet more than a week ago. Scientists are very excited about these machines’ safe landing on Mars. It means that now we have an excellent chance to look for water and other signs of life. So far, the robots have found some stones that could show Mars was once a wet and warm planet.
    But the trips made by Spirit and Opportunity were dangerous. Mars is often called the “death planet”, because in the past its environment has been unfriendly to the robot explorers. Before Spirit and Opportunity, nearly forty spaceships had been sent to Mars since the 1960s. Two-thirds of them failed. The first spaceship, Korabl, sent in 1962 by Russia was among them. It broke apart (分裂) near the earth.

    Life’s a long, long journey(旅程)” so we are told, and most of us would not set off on a journey, even a short one, without some idea of where we wanted to go. Yet many people travel on life’s journey with no sense of direction at all.
    Setting personal goals can give your life a sense of direction. Goal setting is used by top sports players, successful business people and achievers in all fields. Before you set personal goals, think about what you want to achieve with your life.
    Try to set goals in some of the following categories (类别).
    Education—Will you achieve the educational goals after finishing high-school? Are you still growing and learning
    Family—What kind of relationship do you want with your parents and other family members?
    Creative—Do you want to achieve any artistic goals?
    		Career— What job do you want to take when you grow up? What do you need to make your dream come true?
    Public Service—Do you want to make the world a better place?
    Physical—Are you fit enough to do the things you want to do?
    Pleasure—How do you want to enjoy yourself?
    To help make the process (过程) more manageable, divide your goals into smaller tasks. For example, if you want to reach a main goal in five years, set a three-year goal, a one-year goal, a three-month goal and a one-month goal. Then create a daily To-Do List of things that you should do today. When a goal is achieved, take the time to enjoy your success. This helps you build the self-confidence.
    Remember, your goals can change as time goes on. But be sure your goals are things you hope to achieve, not what your parents, family or teachers want.

    C. The relationship with family members.   
    D The time you’ll spend reaching your goal
    小题3:What’s the best advice to achieve the main goal?
    A．building the self-confidence.
    B．creating a daily To-Do list of things.
    C．dividing your goals into smaller tasks

    B．Not all the people can get success by setting goals.
    C．Enjoying success in one goal can help you do better in the next one.

    Can animals be made to work for us? Some scientists think that one day animals may be taught to do a number of simple jobs. They say that in a film or on TV .We may see elephants, or monkeys, dogs, bears, or other animals doing a lot of things. If you watch carefully, you may find that those animals are always given something to eat in return(作为回报) for doing them.

    The world is not hungry , but it is thirsty . It seems strange that nearly 3/4 of the earth is covered with water while we say we are short of water. Why? Because about 97% of water on the earth is sea water which we can't drink or use for watering plants directly. Man can only drink and use the 3% - the water that comes from rivers and lakes. And we can't even use all of that, because some of it has been polluted .
    　　Now more water is needed. The problem is: Can we avoid (避免) a serious water shortage later on? First, we should all learn how to save water. Secondly, we should find out the ways to reuse it . Scientists have always been making studies in the field. Today, in most large cities water is used only once and then runs to the sea or rivers . But it can be used again. Even if every large city reused its water, still there would not be enough. What could people turn to next?
    　　The sea seems to have the best answer. There is a lot of water in the sea. All that needs to be done is to get the salt out of the sea water. This is expensive, but it's already used in many parts of the world. Scientists are trying to find a cheaper way of doing it. So you see, if we can find a way out, we'll be in no danger of drying up.

    D．3% of water on the earth is sea water.
    小题3:From the passage we learn _________.
    A．if every city reuses its water, we'll be in no danger of drying up
    B．man can only drink and use about 25% of water on the earth
    C．today in most large cities water is used only once
    D．water can be used only once
    小题4:To avoid the serious water shortage , which of the following is the most important?

    The weather is getting gotter. You are thirsty after playing basketball or riding home from School. A cold drink may be just the thing. But be careful of what you are drinking. Something that looks cool may not be good for our health. There are plenty of "energy drinks" on the market. Most of
