Healthy Eating

There is much debate nowadays as to what makes up a healthy diet. For example, scientists have insisted for years that a big enemy of health is fatty food. 【小题1】 People who receive 25% of their daily calories (热量)or more through sugar are twice as likely to die from heart disease than people who receive less than 10% a day.

【小题2】 On average, people get 1/3 of their sugar through sweet drinks alone. You need to limit yourselves to less than 100-150 calories a day from sugar. In other words, if you want to be healthy, you have to cut down on desserts, and cut out sweet drinks altogether.

Beyond this, you can keep healthy by consuming different types of fresh foods, which are full of vitamins and fibre, rather than processed foods. It is also important to have some meat, beans, or dairy products in your diet. As with everything in life, moderation (适度)is key. 【小题3】

Finally, a key to healthy eating is to eat slowly. It takes about twenty minutes from the time you start eating for your brain to tell your body that you are full. 【小题4】 In addition, studies show that consistent eating habits, for example, taking three meals a day at the same time each day, are better for our health.

There is no one secret to healthy eating. 【小题5】One question you can ask yourself is, “Do I eat to live, or live to eat?” It is up to you to decide how you want to live, and to make the right decisions about your diet.

Too often young people get themselves employed quite by accident, not knowing what lies in the way of opportunity for promotion, happiness and security. As a result, they are employed in doing jobs that afford them little or no satisfaction. Our school leavers face so much competition that they seldom care what they do as long as they can earn a living. Some stay long at a job and learn to like it; others leave one for another looking for something to suit them. The young graduates who leave the university look for jobs that offer a salary up to their expectation.

Very few go out into the world knowing exactly what they want and realizing their own abilities. The reason behind all this confusion is that there never has been a proper vocational (职业的) guidance in our educational institution. Nearly all feel their way in the dark. Their chief concern when they look for a job is to ask what salary is like. They never bother to think whether they are suited for the job or, even more important, whether the job suits them. Having a job is more than merely providing yourself and your dependants (受赡养者) with daily bread and some money for leisure and entertainment. It sets a pattern of life and, in many ways, determines social status in life, selection of friends, leisure and interest.

In choosing a profession you should first consider the type of work which will suit your interest. Nothing is more pathetic than taking on a job in which you have no interest, for it will not only ruin your talents but also discourage your desire to succeed in life.

First aid is the emergency care for a victim’s (受害人) sudden illness or injury until more skillful medical treatment is available.First aid may save a life or improve certain vital (生命攸关的) signs including pulse, temperature, an unobstructed airway, and breathing.In minor emergencies, first aid may prevent a victim’s condition from worsening and provide relief (解除) from pain.First aid must be carried out as quickly as possible.In the case of the seriously injured, a few minutes can make a difference between a complete recovery and the loss of life.

First-aid measures depend upon a victim’s needs and the provider’s level of knowledge and skills.Knowing what not to do in an emergency is as important as knowing what to do.Improperly moving a person with a neck injury, for example, can lead to the everlasting spinal injury and paralysis (永久性脊髓伤害和瘫痪).

Despite the variety of injuries possible, several principles of first aid can be used for all emergencies.The first step is to call for the professional medical help.The victim, if conscious (有知觉的), should be reassured that medical aid has been requested, and asked for permission to provide any first aid.Next, assess (估计) the scene, asking other people or the injured person’s family or friends about details of the injury or illness, any care that may have already been given, and preexisting conditions (原先就存在的疾病) such as diabetes (糖尿病) or heart trouble.Unless the accident scene becomes unsafe or the victim may suffer further injury, do not move the victim.

First aid requires rapid assessment (估计) of victims to determine whether life threatening conditions exist. One method for evaluating (估计) a victim’s condition is known by the acronym (只取首字母缩写词) ABC, which stands for:

A－Airway: Is it open and unobstructed?

B－Breathing: Is the person breathing? Look, listen, and feel for breathing．

C－Circulation: Is there a pulse? Is the person bleeding externally (体表上)? Check the skin color and temperature for the additional indications of circulation problems．

Once the obvious injuries have been evaluated, the injured person’s head should be kept in a neutral position in line with the body. If no evidence exists to suggest the potential skull (头骨) or spinal injury, place the injured person in a comfortable position. Positioned on one side, a victim can throw up without choking (窒息) or obstructing the airway.
