There are some injuries that are common to all types of extreme sports. The following are some of the important things to do to prevent extreme sports injuries  71  But , they can definitely minimize the risk of injuries .

Warm up.

 72  They include a combination of cardiovascular ( 心脑血管的 ) exercises , strength drills and stretching . Cardiovascular exercises increase body temperature, heart rate and blood circulation, which is required for further movement of the body, Strength drills increase the stamina(耐力)of the body, while stretching warms up the muscles preparing them for sudden forceful movements.   73   It also plays an important role in boosting the team spirit for a team sport. A warm-up session should last for at least 20 minutes and it can extend up to half an hour.

Avoid overworking.

There are some people who do not exercise their body for the sport on a regular basis and perform a week’s task in a day or two.   74   They do not realize the effect of overworking during the performance and keep doing it until they feel extremely tired. Apart from the actual sport, one should also avoid overdoing the warm-up exercises before the activity.

Just as warming up is essential before any rigorous physical activity, cooling down the body after playing a rigorous sport is also a significant part of physical conditioning. When you are done with your sports session, you can conclude with some walking, jogging or light running. Slight stretching exercises, focusing on specific muscles, will also be useful for cooling down the body.

ACool yourself down.

BLook for a coach to train you.

CThese people are likely to suffer from extreme sport injuries.

DHowever, there are no perfect methods which can assure you 100% safety.

EAlong with physical preparation, warming up prepares you mentally to begin a sport.

FYou should also be careful about your clothing selection for warmth and protection.

GWarm-up exercises are very important before you before you begin any sports practice.

London has become a cycle friendly zone after the launch of a new bike hire scheme. It has been designed to encourage more people to cycle in and around central London.

So how does it work?First you have to sign up to the scheme to be sent a key. The key will unlock one of the bikes,which are kept at docking stations in and around central London. You have to pay an access fee for the key and then you pay as you go,for the length of time you use the bike.

Transport for London,which runs the scheme,are hoping to have 6,000 bikes and 400 docking stations in place by the end of the year. The new hire system is hoping to ease congestion (拥挤) in London and is expected to create up to 40,000 extra cycle trips a day into the city center. London Mayor Boris Johnston launched the scheme and said London had been “filled with thousands of gleaming machines that will transform the look and feel of our streets and become as commonplace on our roads as black cabs and red buses”.

However,there have been a few problems since the scheme was launched last Friday. On the first day some people found they couldn't dock their bike properly and their usage of the bike had not registered. Transport for London did admit they had been expecting a few “teething problems” and have said they wouldn't charge for the first day as a “gesture of goodwill”. Some other people have criticized the lack of docking stations and locks for the bikes as well as the price it costs to hire the bicycles.

Despite the comments,the green-thinking London Mayor still seems very positive about things,saying,“My campaign for the capital to become the greatest big cycling city in the world has taken a big pedal-powered push forwards.”

We all eat when we are not hungry. If we stopped eating when we were full, we would be thin , and chefs would have to find other jobs . You may be tempted to eat when you are bored, tired, angry or simply sitting in front of food that you feel like putting in your mouth. Don’t give in , the diet plans warn. Or, if you must eat , then eat only food that is so unappealing or unsatisfying that it is not worth the effort .

It is as important for the sake of losing weight as understanding why there are times when it is extremely important to eat, however, even when there is plenty of food in your stomach. If you find yourself unable to resist snacking and give in and eat a sweet or snack, don’t blame your lack of willpower. Your brain is making you do this.

This request for carbohydrates , for sweet or starchy ( 富含淀粉的) food is a signal that an important brain chemical needs to be made . This chemical is serotonin ( 血管收缩素)its production depends on what you eat or don’t eat . When you eat carbohydrates (apart from the carbohydrates in fruit ) , serotonin is made . When you eat protein, serotonin is not made.

Some of us have brains that don’t make enough serotonin to last all day, and by late afternoon, we feel the effects of too little of this chemical. We become bored, have difficulty concentrating, lose patience with things that annoy us , and feel tired . Therefore, more serotonin is needed. A food scientist said. “We found out years ago in our research that , at moments like this , the brain sends out a signal saying ‘eat some carbs ’ . If we pay attention to this message and eat a bar of chocolate or cake , as soon as the snack is digested , serotonin is made and we feel better .”

  A. Don’t stop eating when you are full.  B. Don’t eat when you are not hungry.

  C. Eat a little more when the stomach is full . D. You would be thin if you ate less.

66. Which of the following will NOT be affected if there’s not enough serotonin?

           The National School Lunch Program

The majority of America’s schools participate in the National School Lunch Program (NSLP), which provides low-cost or free lunches to more than 30 million kids a day. Signed into law in 1946 by President Harry S. Truman, the government originally started the program to absorb remaining farm products, while providing meals to school age children.

Any school district or independent nonprofit school participating in the NSLP receives cash and food from the U.S. Department of Agriculture (USDA). In turn, the school’s meals must meet national nutrition requirements which are as follows:

No more than 30 percent of the meal’s calories may come from fat. Meals must provide one-third of the recommended protein, Vitamin A, Vitamin C, iron and calorie intakes.

It is worth noting that many experts feel these national nutrition guidelines are out of date and that some fast food provided by the NSLP isn't much healthier than some fast food. President Obama’s White House chef , for example, states the NSLP meals are high in fat. Parents and nutrition experts alike are calling for a complete review of the program.

Budget Challenges

Providing healthy school lunches within a limited budget is a challenge. Most schools today don’t even have full kitchens due to school lunch budget drops. Food is instead prepared outside or simply heated up and served at the school.

School Lunch Alternatives

Some school districts may find the NSLP unsatisfactory and instead provide other options. For example, the Farm-to-School Program aims to connect schools with local farms. Students can learn about the journey of their food “from farm to fork”, and local products appear in school meals. School gardens also provide opportunities for nutrition education, as well as produce food that can be offered at the school cafeteria. Of course, these programs require money and resources, and it is up to the school district to figure out how to get them.

In our home it was natural to fear our father. Even our mother was afraid of him. As children, my sister and I thought every family was like that ----- that every family had an unpredictable dad who was impossible to please and a praying mom who was there to protect the children. We were good children. Mom was always telling us we were, even if daddy couldn't see it.

Then came the day we found something new and fun to do. We discovered we could draw pictures with chalk on our wooden front door. We could have lots of fun, so we set to work drawing and making lots of pretty pictures all over it. We had a great time. We decided to finish our pictures, knowing mom would just love them.

The praise we expected did not come. We did not understand why, but we knew all about anger, and that we were in big trouble! Off we ran to find a place to hide. In our wooded yard it was not hard for two small children to find safety. Together, we hid behind a tree and did not move. Soon we heard the frightened voices of mom and our neighbors calling out to us. We were afraid we would be found. The sun set, and it began to get dark. Those around us became more anxious, and we became more frightened. As we stayed together in the dark, we heard another voice, one we recognized with great fear: our daddy. But there was something strangely different about it. In it we heard something we had never heard before: fear and despair. Our daddy with tears running down his face, promising God his life for the safe return of his girls.

Things were different after that. We had a new daddy; it was as if the old one had been buried that day in the yard. Our whole family had been changed by one piece of chalk.
