You eitherhave it, or you don't—a sense of1that is. But2isit that some people could find their way across the Sahara without a map, whileothers can3themselves in the next street?

    Scientistssay were all4with a sense of direction, but it is notproperly understood how it works. One theory is that people with a good sense ofdirection have worked hard at5it. Research being carriedout at Liverpool University supports this idea and suggests that if we don't useit, we lose it.

    Childrenas young as seven have the ability to find their way6,"saysJim Martland, Research Director of the project. "However,7theyare not allowed out alone or are taken everywhere by car, they will8developthe skills. "

    Jim Martlandalso emphasizes that young people should be taught certain9toimprove their sense of direction. He makes the following suggestions:

    If youare using a map, turn it so that it10to the way you are facing

    If youleave your bike in a strange place, put it near11likea big stone or a tree. Note landmarks on the route as you go away from your bike.When you return, go back along the12route.

    Simplifythe way of finding your direction by using lines such as streets in a town, streams,or walls in the countryside to guide you.13yoursteps14you know how far you have gone and note anylandmarks such as tower blocks or hills which can help to find out were you are.

    Now youwill never get lost15!

Dear Doctor,

I am a sixteen- year- old student and I' ve been experiencing lots of back pain and headaches lately. I'm unsure about    the cause. Like some of my friends, I spend my evenings playing computer games and surfing the Internet. What's more, I carry a heavy schoolbag to school daily. I'm just an ordinary student, but these health problems are starting to worry me. What can I do?

Dear Adam,

I'm unable to tell you exactly what's wrong, but I can offer some advice. First of all, don't spend too much time on    your computer, and stop using it late at night. It's important for teenagers to get enough sleep. Also, you get headaches from looking at computer screens for a long time. If you sit on a chair for long, it can make your back so re too. As for your schoolbag, it's important to manage its weight. Take anything you don't need out of your schoolbag. If possible, leave some books or materials at school.

I hope my advice is helpful. Anyway, I strongly recommend you visit a local doctor for that.

One day, I happened to meet an Englishman in a store and soon we began to talk. As I was talking about how I was studying English, the foreigner seemed to be very surprised, gently shaking his head and saying, "You don't say! You don't say!"

I was puzzled（困惑的）, and I thought, "Perhaps this is not a right thing to talk about."So I said to him,"Well, shall we talk about the Great Wall? Have you ever been there?" "Certainly. When I'm back home, everyone will laugh at me if I leave here without seeing it. The Great Wall is wonderful!" he answered. "Yes, it is one of the wonders in the world. And people from all over the world have come to visit it," I added. As I was telling him more about it, he said again, "You don't say!" I couldn't help asking, "Why do you ask me not to talk about it?" "Well, I didn't ask you to do so,"he answered, greatly surprised. "Didn't you say ‘You don't say!'?" I asked again. Hearing this, the foreigner laughed loudly. He began to explain. " ‘You don't say!' means‘Really?'. Perhaps you know little about English idioms（习惯用语）."

Wow! How foolish I was! Since then I have been careful with English idioms. 

Anything Is Possible

by Cotney Moore

When I was just a little girl

Trying to walk there to here

My parents urged, "Anything is possible"

And I took one more step near. 

When I was a little older

Trying to ride my bike

My dad said, "Anything is possible"

And I rode till ____. 

When I was in the fourth grade

With work that was very new

My mom whispered, "Anything is possible"

And I made it through. 

Now my sisters face_these_challenges

That I once went through

I say "Anything is possible"

To them and now to you.
