                                                    Applying (申请) to colleges in America

    One of a high school student's most important tasks is to get into college. Applying to colleges usually

begins in a student's last year at high school, but preparations bgein much earlier.

    Each high school has at least one special college counselor (顾问) to help students apply to colleges.

In public schools, there are about five hundred to a thousand students who have a counselor, but in private

schools, there are usually no more than forty students to every counselor.

    Starting in ninth grade, students have to work hard to get good grades. Colleges lookat all the student's

high school grades, so they are very important. Sometimes, a student can be rejected (拒绝) by a college

just because of poor grades a few years ago.

    In eleventh grade, students begin to take many national tests. Most tests happen a few times a year, and

students can take them as many times as thay want. Colleges only ask for scores from the SAT test

(学业水平测试), which have three subjects-math, reading and writing. However, many students choose

to take other tests as well. These other tests help to show colleges how good a student is.

    In class, students try to behave well for the teachers. Most colleges ask students to have two

recommendation letters (推荐信) from two teachers. Because of this, it is important for students to have

teachers who like them.

    Besides work in the classroom, colleges also think about what the student does outside of school. Students

can join the school and, or write for the school newspaper. Others play on school sports teams. There are

many things for everyone to do, and colleges think it is important to accept students who do things other than

school work.

    After working for so many years, students sendapplication to colleges in the middle of their last year of

high school. A few months later, colleges mail their decisions out.
