Take control of your health by learning these four numbers. They’ll help with everything from losing weight to protecting your heart.

Your daily calorie needs

This is not technically a measurement, but it can have a huge influence on your health. Most women need 2,000 calories a day for good health, and men generally need about 2,550. One way to work out your daily calorie needs is to multiply (乘以) your weight in pounds by 13 to 15, depending on your activity level. But roughly, that’s 300 to 400 calories for breakfast, 500 to 600 for lunch, and 600 to 700 for dinner. Trying to lose weight? Eat about 500 calories less.

Your waist size

Waist size is one of the best ways to measure whether your weight is affecting your heart health. When body fat is packed into your abdomen (腹部),your risk of heart attack increases. For women, health risk begins to rise when your waist is more than 35 inches. For men, risk increases with a measurement when your waist is over 40 inches.

 Your blood pressure

Blood pressure rises and falls normally during the day. When it remains high, you have high blood pressure and this carries a higher risk or heart disease and stroke.

A reading of 140/90 mm Hg or more is considered high, and if it’s between 120/80 and 139/89, you may still be at risk and should be taking steps to prevent the development of high blood pressure.

Your morning pulse rate

Your pulse rate is the number of times your heart beats in one minute. A normal resting pulse rate is 60 to 90 beats per minute. People who are fit tend to have lower resting pulse rates because their heart muscles are in good shape. But if you don’t exercise regularly and your heart rate is lower than the normal range, tell your doctor—it could be a sign of heart disease.

Five steps to take if your child is being bullied
  51  The worst thing you can do is ignore it. Too often parents feel children and teens need to “work things out” on their own. If the problem is ignored, your child’s self-esteem will become unhealthy, he will be hurt mentally or physically, and he could become a bully himself.
Here are five steps you can take if your child is having problems with a bully:
  52  This is an important first step and will help your child trust that you are able to help him with his problem. Accept what he has to say at face value by using your active listening skills.
Let your child know that he is not alone.   53  Reassure your child that he is not the problem. Nothing he did caused the bully to go after him.
If your child is being threatened in a physical or illegal way at school, report the problem. Your child may not want you to do this, or the school may not take it seriously, but violence cannot be tolerated.   54  You will need to model assertive (果断的) behavior by alerting those in charge where the bullying is taking place.
Teach your child assertive behavior and how to ignore routine teasing. Let them know it is okay to say “No.” sometimes even friends bully, so letting your child know they can be true to their own feelings and say “No” can go a long way.
  55  Giving up possessions or giving in to a bully in anyway encourages the bully to continue. Identify ways for your child to respond to a bully---showing assertive but not aggressive behavior---and role-play them.

Major Cities Take Steps to Protect Water Resources
Faced with the threat of water shortages, Beijing and Shanghai will take effective measures to save water and protect water resources.
Beijing will stick more strictly to water-saving policies through the readjustment of industrial structures. Beijing is expected to be short of 1.185 billion cubic meters of water by 2020. Beijing will shut down factories with high water consumption and pollution including electric power, steel and paper manufacturing equipments. Advanced water-saving technology will be introduced to new industrial projects in the capital city.
Grain-growing areas will be reduced to save ground water and more trees will be planted. Animal breeding and other “highly efficient” agriculture with modern water-saving irrigation methods will be developed.
