The human body is a living machine ,and, like all machines, it needs fuel to supply it with energy. This is provided by the food we eat. But how much do we need to stay healthy?

The energy value of food is usually measured in calories. A calorie is the amount of heat required to raise the temperature of 1 kg of water by 1℃.The number of calories people need per day is different, as the chart below shows. Also, the number of calories you use at any moment normally depends on the activity you are in. For example, you need more calories for standing than for sitting, more for running than for walking, and so on.

The energy in food is mainly in the form of three kinds of chemical materials—carbohydrate(糖类),protein and fat. Carbohydrate provides 3.8 Cal/gm(calories per gram) of energy, protein 4.0 Cal/gm and fat 8.8 Cal/gm. Each food contains different amounts of these materials, as the second chart shows.

As the global financial crisis hits the economy, it’s tough finding a job — especially if you’re competing with thousands of other hopeful students. Sometimes you get the interview, but don’t quite seem to land the job because you don’t have related experience. Don’t despair! Here are a few tips that might give you an edge.
1. Get connected to your network and try to expand it. Talk to friends, family and acquaintances. Let everyone know you are looking for a job.
2. Prepare your resume (个人简历) carefully and be sure it’s perfect. Have someone else read it over for typos (打字错误) and grammatical errors. Get professional help. It’s worth the money to present yourself well. If money is tight, read books on resume writing from your public library or search for free help on the Internet.
3. When you apply for a job, be sure you have the skills listed on the posting. If you get an interview, be sure to describe those skills thoroughly. Just having the skills is not enough. Expressing your abilities well can make all the difference in getting the job.
4. Research typical interview questions and practice interviewing. Be well prepared for every interview.
5. Don’t be afraid to accept a position for which you are overqualified — if there’s room for advancements. Many great job advancements come from first doing well at an entry-level position. If you have the right skills and attitude, it won’t be long before you’re in the job you want.
6. Volunteer for a few weeks in your field of study to gain experience if you feel your resume needs an improvement.
7. When deciding what to wear for an interview, think about the position level and the dress code of the organization.
8. Use every tool available to you. For example, this site has many job links for your use.
Good luck!

Carrot juice, because of its many healthy benefits, is commonly called the "magic juice". It has been found that adding carrot juice to people’s diets greatly improves their health. And its delicious taste makes it popular with all members of the family as a beverage.

Carrot juice is one of the richest sources of vitamin A that can be used in the daily diet. Lack (缺乏) of vitamin A can cause dryness and damage to the skin, nails and hair.
