    C. Set a Down-to-Earth Goal
    D. Prepare Yourself Emotionally
    E. Look for a competitive college
    F. Consider Talent Search Programs in Junior High
    Many aspects of college planning are the same for most college-bound students. However, if you’re in any academically gifted and talented program, you have additional things to think about. Here are some actions you should consider.
    小题1:.______
    Talent search programs provide educational opportunities for seventh-and eighth-graders who are mathematically or verbally talented. Some of these programs use SAT scores to identify academically gifted students. Although most students take the SAT in junior or senior year of high school, gifted and talented student often take it earlier.
    小题2: ______
    Many gifted students have the potential to succeed in multiple academic areas. Don't miss opportunities by focusing too early on one that you excel in; carefully examine all your strengths and interests. Discover what you really like to study and the topics you may want to pursue in college. Pursue your interest and passion for learning to the fullest extent possible while you’re still in high school.
    小题3:______
    Gifted students often feel that they have to be accepted by very competitive colleges to be considered successful. And while a competitive college may be the right place for you, don’t let selectivity be the only factor. The most important aspect of college planning is finding a college that’s a good fit.
    小题4:______
    Many gifted students are used to being at the top of their junior high and high school classes. Be prepared to meet other gifted students in college — students who do just as well as you, or better, in the classroom. It can be unsettling. Handle it by staying focused on your own studies and skills and aiming to do your personal best.
    小题5:______
    Although your academic qualifications and abilities may exceed those of your high school classmates, your age is the same as theirs. High school is a time for adolescence, while college requires emotional maturity. A 15-year-old high school graduate may not be prepared to live on a campus 1,000 miles from home with other students who are 18 and older. Think about what you are ready for emotionally, as well as academically, when you’re narrowing down your college list.

③十位整数序数词的构成方法是将基数词的词y变成i,然后再加eth。
例:twenty→twentieth
        thirty→thirtieth
        forty→fortieth
        ninety→ninetieth
④两位或两位以上的基数词变成序数词时,仅将个位数变成序数词。
