Teenagers’fitness is now a major concern...

    Teenagers’fitness is now a major concern, and physical exercise is very important. It reduces stress and improves fitness. Exercise makes your body strong, and helps you to keep the right body weight. Sports scientist Dr. Helen Lopez offers the following advice to teenagers: “First, you need to find out your present level of fitness. Then you can design a programme that will help you become healthier.”

Dr. Lopez suggests that there are three levels of fitness that need a change of lifestyle. “Overweight” means that the person gets very little exercise and often has a serious weight problem. “Inactive” means that the person does not join in many physical activities, but is not seriously overweight. “Active” refers to people who take part in sports and other physical activities, but do not have a high fitness level.

According to Dr. Lopez, overweight teenagers should work out to keep healthy. “Ride a bike, play volleyball or basketball for a while, and go for a twenty-minute walk each day. All these will help to burn calories.” Inactive teenagers should do similar activities, but add some bending and stretching exercises, such as push-ups and sit-ups, starting with twenty of each a day. “Inactive people can take a little more exercise than overweight people because their bodies are stronger,” Dr. Lopez said. The same rule applies to (适用于) active teenagers.

Dr. Lopez suggests one hour a week or more on running and other forms of intensive exercise, together with fifteen minutes a day spent on stretching and bending activities.

“These are really important in order to prevent injuries,” Dr. Lopez said. Some weight-training and other body-strengthening exercises could also be planned in the programme in order to increase the person’s strength.

Homework

Do maths problems 15 through 25. State the different forms of the verbs on page 50 of your French workbook. Read pages 12 through 20 of the Shakespeare play, and don’t forget to fill in the missing chemical symbols on the worksheet.

Sound like a list of your homework for the next few nights — or maybe even just for tonight? 1.It’s your teachers’ way of evaluating how much you understand what’s going on in class. And it helps strengthen important concepts. Here are some tips on how to do your homework.

2.It’s inviting to start with the easy things to get them out of the way. However, you’ll have the most energy and focus when you begin, so it’s best to use this mental power on the subjects that are most challenging. Later, when you’re more tired, you can focus on the simpler things. If you get stuck on a problem, try to figure it out as well as you can — but don’t spend too much time on it because this can mess up your homework schedule for the rest of the night. 3.But don’t pick someone whom you’ll be up all night chatting with, or you’ll never get it done!

Most people’s attention spans aren’t very long, so take some breaks while doing your homework. Sitting for too long without relaxing will make you less productive than if you stop every so often. Taking a 15-minute break every hour is a good idea for most people.4.

Once your homework is done, you can check over it if you have extra time. Be sure to put it safely away in your backpack—there’s nothing worse than having a completed assignment that you can’t find the next morning or that gets ruined by a careless brother or sister. 5.Now you’re free to hang out.A. Luckily, you can do a few things to do less homework.

B. Homework is a major part of going to school.C. No one is expected to stay long, and people have very different learning styles.

D. If you need to, ask an adult for help or call or email a classmate for advice.

E. But if you’re really concentrating, wait until it's a good time to stop.F. And no teacher still believes that “chewed by the dog” line—even when it's true!

G. When you start your homework, deal with the hardest tasks first.
