  War, money and power are a few things that countries and people are concerned about.  1  I agree that those things are important, I believe that everyone should start to  2  more on a growing problem-global warming.

  Global warming will not only  3  our country and our generation, but also the entire  4  and future generations.It is  5  because the weather has been a lot warmer over the past few years, which  6  the melting(融化)of the ice in the Antarctic.This will soon cause water levels to  7  and flood parts of the world.

  Many people ignore this problem because they feel  8   they can't do anything about it and have more  9  things to worry about.If we all  10  so, then our ozone layer(臭氧层)will be  11  and the planet will no longer be able to make life continue to exist.We should do our best to limit the use of our planet's  12  resources(资源)and keep our air clean.  13  , future generations will suffer from our  14  .

  Some might feel that they can't stop global warming from  15  .But if every single person does his or her part in keeping the air clean, then it will become a  16  effort.Sure, there are some things that cause pollution and that we won't be able to  17  change.This may include cars burning oil, but we can  18  adjust some of these things.People can start carpooling, taking the bus, riding their bikes, or  19  just walking.

  If everyone takes  20  now, I believe we can start seeing remarkable results within a few years.

 Laptop(便携式电脑) computers are popular all over the world. People use them on trains and airplanes, in airports and hotels. These laptops connect people to their workplace. In the United States today, laptops also connect students to their classrooms.

  Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork anywhere they want. Within five years, each of the 1500 students at the college will receive a laptop. The laptops are part of a $10 million computer program at Westlake, a 110-year-old college. The students with laptops will also have access to the Internet. In addition, they will be able to use e-mail to “speak ” with their teachers, their classmates, and their families. however, the most important part of the laptop program is that students will be able to use computers without going to computer labs. They can work with it at home, in a fast-food restaurant or under the trees----anywhere at all!

  Because of the many changes in computer technology, laptop use in higher education, such as colleges and universities, is workable. As laptops become more powerful, they become more similar to desktop computers. In addition, the portable (手提式)computers can connect students to not only the Internet, but also libraries and other resources. State higher-education officials are studying how laptops can help students. State officials are also testing laptop programs at other universities, too.
