The computer makes doing schoolwork easier for me than it was for my mom and dad. For example, when writing book reports and stores, I use Microsoft Word instead of a pen and paper. That way, after my teacher edits（编辑） my work, I can go back and make revisions without having to rewrite the whole thing. And Microsoft Word has a spell check! I use it all the time.

For English class, we're reading The Outsiders, by S. E. Hinton. As a pre-reading task, my teacher asked us to research teenage groups on the Internet. I tried Google, Encarta, and Yahoo first, and finally found an article on Time. com.

For a geography task on the United States, I used Encarta to learn about the Mississippi River. I needed to find out how deep the river is, how its widths and depths are different, what states it runs through, and what kind of fish live in it. I used the information to show how the geography of a country influences its economy （经济）. For example, the river's trade paths, the number of fish caught in it, and the tourists it attracts directly influence Southerners' jobs and incomes（收入）.

I never go to the library to do research. It takes too much time. Since I live in New York City and both my parents work, getting to the library isn't always easy. For a big assignment or research project, I used to stay at the library to read, or sign out whatever books or magazine I needed. Now being able to find the information in my own living room makes everything a lot simpler. Online dictionaries and encyclopedias （百科全书） also save time.

Sometimes, I think the computer spoils young people because its so easy---at least physically. But computer's are not like television, which does the thinking for you. You still have to use your mind. I prefer using a computer. Easy, fun, and fast.
