Here are some college characteristics youshould consider.
1)Number of students:
This will be very important, more opportunities and experiences for you, including:
• Range of academic majors offered
• Extracurricular possibilities
• Amount of personal attention you'll receive
• Number of electronic resources, data bases, etc.
When considering size, be very sure to look beyond the raw number of students attending. For example,
perhaps you're considering a small department within a large school. Investigate not just the number of
faculty members, but also how accessible they are to students.
2)Location :
Do you want to visit home frequently, or do you see this as a time to experience a new part of the
country? Perhaps you like an urban environment with access to museums, ethnic food, or major league ball
games. Or maybe you hope for easy access to the outdoors or the serenity of a small town.
3)Academic Programs :
If you know what you want to study, research reputations of academic departments by talking to people
in the fields that interest you. If you're undecided, relax and pick an academically balanced institution
that offers a range of majors and programs. Most colleges offer advising to help you find a focus.
In considering academic programs, look for special opportunities and pick a school that offers many
possibilities.
4)Campus Life :
Consider what your college life will be like beyond the classroom. Aim for a balance between academics,
activities, and social life. Before choosing a college, learn the answers to these questions:
• What extracurricular activities, athletics, and special interest groups are available?
• Does the community around the college offer interesting outlets for students?
• Are students welcomed by the community?
• Is there an ethnic or religious group in which to take part?
• Is housing guaranteed?
• How are dorms assigned?
One of the best ways to measure a school's quality and the satisfaction of its students is to learn the
percent of students who return after the first year and the percentage of students who finish school.

Some traditions of the Chinese New Year.
1. The Chinese believe that as they meet a new year, they should put behind them the things of the past. They clean their house, pay off debts, buy new clothes, paint the doors and window frames and even get new haircuts.
2. Red is the traditional colour of the New Year. It frightens away evil spirits and brings good luck. So many people decorate their houses with the red lanterns. They often wear red clothes as well. At midnight fireworks and firecrackers scare away evil spirits.
3. On New Year’s Eve families gather for a holiday meal. But they never eat meat, that’s traditional. It’s also bad luck to use knifes, scissors or other sharp things at New Year’s dinner.
4. Children wake up early on New Year’s Day. They usually find small red envelopes with sweets or money under their pillows.
5. You have to be happy and polite for 15 days after New Year’s Day!
