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 brain 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.A British scientist found out that ________ could improve our memories.
| A．drink | B．dreams | C．sleep | D．bananas |
According to the passage, if we want to have a good brain, we should ________.
| A．use our brains more | B．sleep fewer hours |
| C．work longer hours | D．remember fewer things |
Which of the following is TRUE according to the passage?
| A．Our brains only work in the daytime. |
| B．Our brains need much energy every day. |
| C．Smoking can keep our brains healthy. |
| D．Getting exercise is good for our brains. |

①Chemistry is everywhere in our daily life．Sometimes it's easy to see．At other times， it can be very hard to see the everyday chemistry at work，but nearly everything you touch has some chemicals（化学物质）in it．
②Chemistry helps to make products for use．Something as simple as toothpaste has at least three chemicals that keep your teeth clean．Other things in your daily life are created by chemistry，such as hair products and soap．Without chemistry， we would never have known that we need soap to get the oil out of clothes．
