1.根据短文理解,选择正确答案。

Yesterday and Today

    Life in the twenty-first century will be different from life today. Between then and now many changes will take place, but what will the changesbe?

    The population is growing fast. There will be many people in world and most of them will live longer than people live now.

    Computers will be much smaller and more useful, and there will be at least one in every home. And computer studies will be one of the important subjects in schools then.

    People will work fewer hours than they do now and they will have more free time for sports, watching TV and travel. Traveling will be much cheaper and easier. And many more people will go to other countries for holidays.

    There will be changes in our food, too. More land will be used for building new towns and houses for all the people. Then there will be less room for cows and sheep, so meat will be more expensive. Maybe no one will eat it every day. Instead they will eat more fruit and vegetable. Maybe people will be healthier.

    Work in the future will be different, too. Dangerous and hard work will be done by robots. Because of this, many people will not have enough work to do. This will be a problem.

4.根据短文理解,选择正确答案。

    Why can't some people even get an inch of what they dream of becoming? Blame it on pure dreaming and lack of setting goals for achieving their dreams.

    Setting goals is very significant part of accomplishing and positive actions. It is like scaling (攀爬) a 200 feet construction and marking in the early hours on what feet you would like to reach at this specific period.

    People who set goals literally generate(形成) a map of their goal settings in life, marking where they should start, where to pause, where to study a bit, and where and when to end. Once this map comes into being, it allows the map drawer to check where he is in the scheme(安排) of things and whether or not he is making some planning that will take him closer to his goals.

    By setting goals, people will know how they are doing and what they should be doing to get their goals or dreams in life. They will know if they can relax or if they have to double their efforts when they are falling short of what is expected of them.

    Goal setting means a person is proactive in dealing with challenges that may affect his plans. Being proactive means one is able to outline possible difficulties that may happen as well as the solutions(解决方法)to these difficulties. By doing this, a person is not easily scared or defeated when challenges happen because he has already prepared for them. He knows they can happen and he has prepared a solution or strategy when that time comes.

    Setting goals will enable people to track their progress in whatever hard work they set out to do. It will help people become more confident in themselves and more motivated to get their plans.
