In recent history, there have been some amazing inventions which have changed our lives. The plane has made international travel faster and easier. The Internet has brought people closer. And you must know the names of some famous inventors like Henry Ford or Steve Jobs. But there are many everyday objects which you probably don't notice and you don't know who invented them. Take for example Nils Bohlin who invented the modem-day car seat belt (安全带).

    Before 1959, only two-point seat belts were available, and the only people who often wore them were race car drivers. The two-point seat belt couldn't protect passengers from internal injuries (内伤) during serious car accidents.

    In 1958, Bohlin joined Volvo Car Corporation as a safety engineer. Then he came up with the three-point seat belt to keep passengers from flying out of their cars during collisions. The three-point seat belt used one strap (带子) across the chest (胸部) and another across the legs and then the two joined at me same place.

    Amazingly, this was a very simple idea which no one had tried before. The three-point seat belt was introduced on Volvo cars in 1959. For more people's safety, Volvo made the new seat belt design available to other car makers for free. Since then, engineers have worked to improve the three-point seat belt, but the basic design remains Bohlin's.

    At the time of Bohlin's death in September 2002, Volvo announced that the seat belt had saved more than one million lives since it was introduced.

    When I was a little girl, my family lived in the countryside. There was a beautiful river near my home. The water was clean and cool. I liked to go fishing there with my mother. We would catch fish, look for clams(蛤)and play in the water. There were also a lot of birds near the river. We would spend all day watching the birds.

    Now my family live in the city. Last Sunday, my daughter asked me to take her to see the river I was always talking about. "I want to go fishing there so much with you and Grandma," she said.

    When we went to the river, we only saw a factory and a mountain of waste. My mother was surprised, my daughter was disappointed, and I was sad. The river was my best friend. I grew up with it. Now there are no fish in it, and the birds have gone too. I hear them crying for help. But what can I do?

You are running in the playground. But then suddenly, you fall and hurt yourself. "Ow!" you cry. This sound is very familiar to us all. Crying out when we get hurt is a natural action. But have you thought about why we shout it out? And do people from different languages make the similar sound? 

Scientists now believe they've found out the reason: shouting the word "ow" partly stops pain messages from traveling to the brain. So by shouting it out, people can feel less pain.

The scientists tested how long volunteers could hold their hands in very cold water. In the first group, they were allowed to shout "ow" when they felt pain. In another group they had to stay silent. The results showed that volunteers were able to keep their hands in the cold water for longer when they were allowed to shout out. Shouting out "ow" helps humans feel less pain and add the time.

What's more, scientists have also found that different languages have similar expressions of pain. While cries of "ow" or "ouch" are heard in English, South Africans yell "eina".

These languages have one thing in common: when people shout them, the mouth simply opens, the tongue (舌头)lies flat and the lips (嘴唇) unrounded. It is a simple sound that requires little control, so it's easy to make a big sound. For the reasons, these sounds are useful to shout if we feel pain.

{#blank#}2{#/blank#}If you don't have time to sit down and have a healthy breakfast, try vegetable juice before you go to school. This is better than coffee.

Eat less salt. {#blank#}3{#/blank#}So eat less or give them up. Stay away from foods with too much fat. You can eat vegetables, fruits, fish and chicken. {#blank#}4{#/blank#}For example, you can eat

chicken hamburgers instead of(而不是) beef hamburgers.
