     The computer makes doing schoolwork easier for me than it was for my mom and dad. For example,

when writing book reports and stories, I use Microsoft Word instead of a pen and paper. That way, after my

teacher edits my work, I can go back and make revisions without having to rewrite the whole thing. And

Microsoft Word has a spell checks! I use it all the time.

     For English class, we're reading The Outsiders, by S.E.Hinter. As a pre-reading assignment, 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 assignment 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 affects its

economy. For example, the river's trade paths, the number offish caught in it, and the tourists it attracts

directly affect Southerners' jobs and incomes.

      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'd have

to stay at the library to read, or sign out whatever books or magazines I needed. Being able to find the

information in my own living room makes everything a lot simpler. Online dictionaries and encyclopedias also

save time.

     Sometimes. I think the computer spoils my generation because it's so easy at least physically. But

computers 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.
