You either have it, or you don’t — a sense (感觉) of direction, that is. 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 (强调) 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 it relates to 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. Note landmarks on the route as you go away from your bike. When you return, go back along the same route.
◆ Simplify the way of finding your direction by using lines such as streets in a town, streams, or walls in the countryside to guide you. Count your steps so that you know how far you have gone and note any landmarks such as tower blocks or hills which can help to find out where you are.
Now you need never get lost again!

I used to be very close to my father when I was a child. He gave me almost everything I wanted. Whenever I quarreled with my mother, I would turn to my father for comfort. He was everything to me.
Time flies like a bird. As I got older, I became silent and found it hard to start a conversation with my father. The gap(代沟) between us began to grow. He had done so much for me but I always took it for granted（理所当然）.
Last time our school gave us two days off, and daddy gave me a ride home on his motorbike. I was tired and fell asleep on his back. Later my mother said he was very happy because it had been a long time since we got close last. Suddenly I felt a little shamed. I realized that I had paid no attention to him a lot during the last few years.
The next day I stayed in bed and when daddy tried to wake me up to have breakfast, I pretended(假装) that I couldn’t hear him. At last he brought a bowl of noodles to my bed, and said, “Come on, dear, have your breakfast and then continue your dream.” I got so angry with him for troubling my sleep that I shouted, “__________.”
As I said this, I sat up quickly, and the bowl of noodles broke on the floor. Hearing the noise, mum came in and shouted at me, “What do you think your father is? Who else treats you as well as he does?”
I was shocked and didn’t know what to say. Finally I rushed with tears all over my face. I went to the pool where I used to go fishing with daddy. A few minutes later, I heard the sound of daddy’s motorbike. He was looking for me worriedly, but he didn’t notice me as I was sitting behind a tall brush.
I didn’t return home until 10 a.m.. The moment my parents saw me, they rushed to me. Mum hugged me tightly and daddy looked at me with worry in his eyes. “Are you hungry, dear?” he said at last. Before I could say anything, he had gone off on his motorbike to buy food for me.
