Lana: I read a report. It said that Dr. Ian Wilmut successfully cloned a lamb* named Dolly from a grown-up sheep. So people call him the “father” of Dolly.
Tony: In fact, the word “clone” means to produce the “same” animal by taking cells* from a
grown-up one. I think, if we know how to do cloning, we need only to keep a small number
of sheep, cows or horses.
Lana: What’s more, these days some people even want to clone humans. They have asked: Can we
clone ourselves?
Tony: It seems interesting. But do you think it possible to do that?
Lana: No, impossible! First, I think we cannot clone a dead person, because the cells in his body are dead already.
Tony: Then can we clone a living person?
Lana: Again no! You might clone yourself one after another, but it is only a copy, not a real you. It is only something, not a “human”.
Tony: Well, you mean that it is not a real human.
Lana: True enough! I think Dr. Wilmut would most like to make better animals, and it has nothing to do with human cloning.

How do you remember the way to your house? Where do dreams come from? It is your brain(大脑) that does these things. A British scientist showed that “sleep can improve one’s memory.” It’s not a dream for students to study when they sleep. In fact, your brains is working day and night. If you learn words before bed, a certain part of the brain may help you to remember the words while you sleep. What’s more, another scientist in the USA found that there was a “talent button(天才按钮)” in the human brain. It might make a person more talented.
There are more interesting things about the brain. Your brain uses less energy than a fridge light. Just two bananas can give the brain enough energy to work for a whole day. According to some scientists, yawning(打哈欠) keeps our brains “cool”, which makes us think quicker.
Here are some pieces of advice to keep a good brain:
Eat healthy food.
Get a lot of playtime or exercise.
Don’t drink or smoke.
Use your brain a lot.
