In many countries, more and more foods have additives in them. What are additives? Additives are chemicals which are put into foods to give them color and taste, to stop them going bad and so on. But doctors say that some additives can be very bad for our health.

Now let’s look at how additives can be bad for our health. Take this for example, a little English girl called Sally Jones is two years old and quite ordinary. But when she was younger, she never went to sleep at night. She never got tired. Her parents were very tired. Finally, Sally’s parents took her to a special doctor.

The doctor said that she must never eat food with additives in it. He was sure that the additives had a very bad effect on her body, and made her too active. He was quite correct. As soon as Sally started to eat foods with no additives, she began to sleep well at night.

Now she is the same as other little girls, except that she can’t eat many foods that other children love, such as ice-creams, because they have additives in them.

【推荐1】We usually go to see a doctor when we are ill. Doctors may give us some medicine, and the medicine often (A) m           us feel better.

But sometimes the doctor’s medicine doesn't (B)           . This happened to one man Thomas Smith. He was ill in hospital, but he wasn't getting well. (C) 之后他在自己体内发现了一个新“医生”。He saw funny films. He read funny books. And something wonderful happened. Laughing took away his pain after half a year. He could have a good night's rest. His own happy feeling helped him get well again. He wrote his story in his book. He said laughing was very useful. (D) It was the best "medicine".

Another man, Simon Beck, was also ill, and he had a serious pain in his back. The doctor couldn't stop it, so the man began to "picture" his pain. In his head he “drew” a picture of a dog. He imagined it to be a real dog. And it was hurting him. Then the man talked softly to the dog. He put his hand on the dog’s head and talked with it. After one year, his pain went away!

These stories may surprise you, but more and more people are getting well in this way. So call on the “doctor” inside your mind, and keep happy and well!

Do you know the reason why we feel tired in the middle of a class? Maybe you would say it is because the teacher’s class is boring. However, the real reason is probably that we don’t have enough sleep. Perhaps this is something you have not paid enough attention to or not yet noticed. Here are what sleep researchers have found about how to sleep.

Why do we need sleep? Sleep helps our body heal, grow, and stay healthy. It also gives us energy, so we can be active all day. Doctors and health scientists say: When you close your eyes and need a rest, sleep is just the very best! This is more than advice.

Enough sleep is important to us how much sleep do we need? It is known that all of us naturally need no less than eight hours of sleep per night. When we sleep below six hours per 24, we’re at an increased risk of health problems. Some of us think we can make up any of those hours lost during the week on the weekends. Sadly, there is no storage (储存) system for sleep in the brain.

New-born babies sleep most of the time. They can sleep 20-22 hours a day. Children need 10-12 hours of sleep a day. Teenagers need 8-10 hours of sleep a day because they need lots of energy to grow into their adult bodies. Grown-ups usually need 6-8 hours of sleep to keep active.

A new research suggests a kind of strong connection between purpose in life and sleep. People who have a greater sense of purpose usually have better physical and mental health, which in turn explains their higher-quality sleep. Perhaps developing a sense of purpose in life could be as useful at improving sleep as the healthy habits above.

Almost everyone has their dreams while they sleep, but not all of them can tell their dreams clearly when they wake up. Some people talk in their dreams. More surprisingly, some may even get up in their dreams and walk around. This is called “sleepwalking”. Are you a sleepwalker? Or, is there a sleepwalker around you?

We have to accept the truth: Sometimes, we just want to shout out loud.

For example, we all have days like this: When we just cleaned our room, the dog made a mess on the floor. Or our friend called to tell us he or she couldn’t come at the last minute after we cooked dinner for him or her. We may be really angry but we tried to bear(忍受) things like those. According to ancient Chinese wisdom(至理 名言), we should shout in a loud voice instead of keeping quiet. In fact, it’s good for our health.

“Chinese people pass on the practice as a part of traditional medicine,” said Mrs. Li, a 60-year-old woman from Hangzhou. “My parents taught me to do this. It ’s a part of our folk(民族) culture.”

Mrs. Li is a member of a group of people, and she loves shouting. Each morning, she and some of her friends climb to the top of a hill and let out loud shouts before starting their daily exercise. They believe that shouting is good exercise for them and it brings them a lot of fun.

“Sometimes I shout out and others shout back,” said Mrs. Gu, another shouting lover. “It makes you happy. You laugh and then you feel very comfortable.”

Dr. Peter Calafiura, an American doctor, agrees that shouting can have a good influence(影响) on people’s health.

So, next time you start your morning run, why not try to shout out first? It will make you healthier.

What do you do when you begin to read an English newspaper?

You'd better know what sections there are. Usually, there is international news, business, science and technology, entertainment and lifestyle, sports and cartoons. You can choose your favourite section to read carefully.

Then, you come to the article itself. If you don't have time to read the whole article, the headline and photo give you a general idea of the story.

Different kinds of articles:

A news article includes body text and a photo with a short piece of text under it. 它通常把最重要的信息放在开头. （1）

A feature article is an in-depth(深入详尽的) report on an event or a person. It usually has an interesting opening. You get to know the idea of the article as you read.

Another kind of article is an opinion (评论) article. Usually, some famous people give their own opinions about an important issue(问题） in a fun way.（2） Opinion is different from news stories that are all facts.

Be a critical(批判性的) reader:

There are advertisements in newspapers.They can provide useful information about products, places, food or jobs. Remember that people make advertisements to sell you things. You don't have to do everything advertisements tell you to do. You should be critical enough to judge which advertisements are useful and which are not.
