Michelle, a famous lady, has found that more than 25% students are too fat in her country. It is a very serious problem. So she starts a health program to deal with it. The health program is to reduce the amount(数量)of fat students today and in the future.

    The program will get families, schools, newspapers, magazines and TVs to join together and deal with the students' obesity so that students will be at a healthier weight. The program includes: food stores should sell healthier food: schools should serve healthier meals with less fat and should also offer gym classes.

    The lady is trying to fight the students' obesity all over the country because it can cause illnesses and higher health cost. She wants the students to eat right, exercise more and control their weight. She also wants the students to understand it is important to have less sweet food, and drink water, milk and fresh juices, but not to choose cokes. At the same time, she has also set a good example by planting a vegetable garden. She hopes that the garden will encourage more people to plant one, too.

    The health program is really helpful to the students today and in the future. As she says, we cannot always build the future for youth, but we can build our youth for the future.

    Haiyan is 7 years old. Her parents gave her an iPad as a gift for her birthday. A month later，her eyesight（视力）dropped to 300 degrees. This is serious for such a young child.

    Many children in China are facing the same problem: iPad using is bringing problems to their eyesight. The problem is so common that newspapers even call the iPad the "No. 1 killer of children's eyesight!"

    "There are about 30 shortsighted children coming every day, "said Hu Dali, an eye doctor at Guiyang Aier Eye Hospital. "Half of those children have poor eyesight because they have played with phones and iPads for too long. "

    Doctors and scientists say children's vision（视觉）is not yet fully developed and their eyes get tired more easily. The screen of an iPad uses very bright（明亮的）LED backlight. If children look at an iPad screen for a long time, their eyes do not have time to rest. This will make their eyesight worse over time.

    Doctors advise that users should hold their iPads between 40-60 centimeters（厘米）away from them. The brightness of the screen should be comfortable for children. Parents should also stop their children from using an iPad for more than one hour every day.

    Did you spend much time lying on the comfortable sofa at home during the summer vacation? How often did you do sports this summer? People across the world need to get moving, according to a new study by the World Health Organization (世界卫生组织).

    5% of adults do not get enough exercise, according to the study. This number hasn't changed from 2001. Because of this, about 1.4 billion people are close to deadly diseases (疾病) such as heart disease and cancer (癌症).

    People should do at least 2 and a half hours of "moderate intensity (中等强度)" exercise each week, such as dancing or swimming. They can also do 75 minutes of "vigorous intensity (高强度)" exercise, such as running or playing soccer, according to the WHO.

    As for how to exercise more, experts says that we don't have to go to the gym (健身房) every time For example, we can go up and down stairs (楼梯) a lot instead of taking the lift. If we can't go to a dancing class each week, standing on one leg for 30 seconds a day is very good too.

    The study also found that women are less active than men, 32% of women hardly ever take exercise, compared to (比较) 23% of men. Women spend more time at home taking care of children and doing housework.

    But unlike that in most other countries, men are less active than women in China, with 16.6% of men and 12% of women not getting enough exercise.

It is easy for many people to catch a cold in the springtime or fall. It makes us wonder if scientists can send a man to the moon, why can't they find a cure for the common cold? The answer is easy. There are actually different cold viruses out there. You never know which one you will get, so there isn't a cure for each one.

When a virus attacks your body, your body works hard to get rid of it Blood rushes to your nose and causes a block in it. You feel terrible because you can't breathe well, but your body is actually eating the virus. Your temperature goes up and you get a fever, but the heat of your body is killing the virus. You also have a runny nose to stop the virus from getting into your cells. You may feel very uncomfortable, but actually your wonderful body is doing everything it can to kill the cold.

Different people do different things to deal with colds. In the United States and some other countries, for example, people might have chicken soup to help them get over the cold. Some people take hot baths. Other people take medicine to stop different symptoms(症状)of colds.

There is one interesting thing to note一some scientists say taking medicine when you have a cold is actually bad for you. The virus stays in you longer because your body doesn't have a way to fight it and kill it Bodies can do an amazing job on their own. There is a joke, however, on taking medicine when you have a cold. It goes like this:

It takes about one week to get over a cold if you don't take medicine, but it takes only seven days to get over a cold if you take medicine.

    Maybe a lot of thin people will be worried about their health if the inside fat matters.

    Some doctors now think that the inside fat around important organs like the heart or liver could be as dangerous as the outside fat which can be noticed more easily.

    "Being thin doesn't surely mean you are not fat," said Dr Jimmy Bell at Imperial College. Since 1994, Bell and his team have tested nearly 800 people with MRI to create "fat maps" showing where people store fat.

    According to the result, people who keep their weight through the food they usually eat rather than exercise are likely to have major deposits (堆积物) of inside fat, even if they are thin.

    Even people with normal Body Mass Index (体重指数) scores can have surprising levels of fat deposits inside. Of the women, as many as 45 per cent of those with normal BMI scores (20 to 25) actually had too high levels of inside fat. Men were nearly 60 per cent.

    According to Bell, people who are fat on the inside are actually on the edge of being fat. They eat too many fatty and sugary foods, but they are not eating enough to be fat. Scientists believe we naturally store fat around the stomach first, but at some point, the body may start storing it elsewhere.

    Doctors are unsure about the exact dangers of inside fat, but some think it has something to do with heart disease and diabetes (糖尿病). They want to prove that inside fat does harm to the body's communication systems.

    The good news is that inside fat can be easily burned off through exercise or even by improving your eating habits. "If you want to be healthy, there is no other way. Exercise has to be an important part of your lifestyle," Bell said.
