You either have it, or you don’t－a sense of direction. But why is it that some people could find their way across the Sahara without a map while others can lose themselves in the next street?

Scientists say we’re all born with a sense of direction, but it is not properly understood how it works. One theory is that people with a good sense of direction have simply worked harder at developing it. Research being carried out at Liverpool University supports this idea and suggests that if we don’t use it, we lose it.

“Children as young as seven have the ability to find their way around,” says Jim Martland, research director of the project. “However, if they are not allowed out alone or are taken everywhere by car, they never develop the skills.”

Jim Martland also emphasizes that young people should be taught certain skills to improve their sense of direction. He makes the following suggestions:

If you are using a map, turn it so that it relates to(与……有联系) the way you are facing.

If you leave your bike in a strange place, put it near something like a big stone or a tree－something easy to recognize. Note landmarks on the route as you go away from your bike. When you return, go back along the same route.

Simplify(简化) the way for finding your direction by using lines such as streets in a town, streams, or wells in the countryside to guide you. Count your steps so that you know how far you have gone and note any landmarks such as towerblocks or hills which can help to find out where you are.

Now you will never get lost again!

Look closely at your hands. Are they clean? It doesn't matter how many times you wash your hands, tiny microbes (微生物) still stay on them. But don't worry. Most microbes don't harm you.

Now scientists say the microbes on our hands could be used in a surprising way; fighting crime, According to a recent survey microbes as well as fingerprints(指纹) could be used to indentify the criminal.

Everyone has his own set of microbes on the hands. That is to say, if you and your best friend were able to see and compare all the microbes on your hands, your hands probably would look different. Some microbes only show up on your hands while others live only on your friend's hands.

When you work on a computer you leave the microbes from your hands on the keyboard. The scientists can easily tell the owner of the keyboard by looking at the microbes on it. Even if you don't leave your fingerprints behind, your microbes may give you away.

Noah Fierer, a scientist, says. "You can only clean a fingerprint, but you can't sterilize (使无菌) a surface just by wiping(擦) it off," He says that scientists have a lot more work to do before the microbe is used as a useful tool.

Happiness is for everyone, and you don’t need to care about those people who have beautiful houses with         and swimming pools or those who have nice cars         a lot of money and so on. Why? Because those who have big houses may often         lonely and those who have cars may want to walk on the country roads in their free time.

In fact, happiness is always around you if you put your heart into it. When you are  in         at school, your friends will help you; when you study at your lessons, your parents are always         good care of your life and your health; when you get        , your friends will say congratulations to you; when you do something wrong, people around you will help you to         it. And when you do something good to others, you will feel        , too. All these are your happiness. If you notice those things, you can see that happiness is always         you.

Happiness is not the same as money. It is a feeling of your heart. When you are        , you can also say you are very happy because you have something else that can’t be bought with money. When you meet difficulties, you can say loudly you are very happy because you have more chances to         yourself. So you cannot always say you are poor or you have bad luck. As the saying goes: Life is like a revolving(转动的)door. When it        , it also opens. If you take every chance you get, you can be a happy and lucky person.
