Do you have a good memory? Maybe you remember better than all of your friends. But even if you have a short-term memory, it’s better than a chimpanzee’s(黑猩猩), right? Well, you may be wrong.
Tetsuro Matszawa, a scientist from Kyoto University, Japan has showed how chimps have far better memories than humans. “We learn that chimps have great memories by doing tests,” he told The Guardian “You can do things to improve your memory.”
How do chimps have better memories than us? Scientists tested four chimps and human volunteers. They showed them five numbers on a computer screen. Chimps and human volunteers had to remember the numbers correctly. But to make it hard, the numbers disappeared(消失) after seven tenths of a second. Then they will reduce(减少) the time to two tenths of a second. While humans began to make mistake after mistake, the young chimps still did very well.
Why do they have better memories? We share 98.8 percent of our DNA with chimps. But during evolution(进化), we lost some of our shared abilities. As humans learned new skills, like language, we had to lose some of our memory skills to make room in our brains. “To get something, we had to lose something,” said the scientist.
Chimps need good memories to survive(生存). When a chimp looks up at the big tree and pick a banana, he must remember where he saw it as he fights off competition from other animals.What did the scientist’s study find?
| A．Chimps can remember all of their friends. |
| B．Chimps have better memories than humans. |
| C．Chimps do things to improve their memories. |
| D．Chimps can do many things better than humans. |

| A．Five chimps and human volunteers were tested. |
| B．The numbers first disappeared after a second. |
| C．Humans made fewer mistakes than chimps. |
| D．The chimps did a better job than humans. |

Peter always doesn’t know the way. His friends often laugh at him. They say he needs a map to find the bathroom in his own house. In his eyes, every street looks the same, and he doesn’t know which way to go. Sometimes he has to take a taxi home because he can’t remember the way to his house.
Peter watches a lot of films and reads a lot of books about animals. Each bird knows which way is south. Bats (蝙蝠) can fly at night and find their way with their ears.

During the day we work and play，and at night we sleep. Our body rests when we sleep. In the morning we are ready to work and play again. Our body grows most when we are asleep. Children who are tired usually need sleep. We can get better at our lessons after having plenty of rest. Boys and girls who are 8 or 9 years old need 10 hours of sleep every night. Our body needs plenty of air when we are asleep. If we do not get enough fresh air, we will feel tired when we wake up. While in bed we must not cover our head，our lungs need to get enough fresh air. If we open our windows at night，we can have plenty of fresh air. Cool air is better than warm air. Boys and girls who want to be strong must get plenty of sleep.（plenty of: 大量的、充足的）
