Many people go to school for an education. Some learn languages, history, math and other subjects. Others go to school to learn a skill. School education is very important and useful. Yet, no one can learn everything from school. A teacher can not teach his students everything they want to know. So, much more is to be learned outside school by the students themselves.
Great people before us didn’t get everything from school .Their teachers only showed them the way. Edison did not even finish school. But they were all so successful because they knew how to study. They read books that were not taught at school . They would ask many questions as they read. They worked hard all their lives. Above all , they knew how to use their heads.

Early in the morning, at noon, or in the evening in big cities and in the countryside, all over the United States, you can see Americans running — men and women, young and old. People run — along the beaches of California, Central Park in New York, down quiet streets in small towns or at the gym. Some people even run in living rooms.

Height is just one of the features your genes (基因) decide. In fact, because you have two parents, your genes provide you a height that usually lands somewhere between the height of each parent. If both your parents are tall, then most probably you will be tall, too. But if you have questions about how tall you’re going to be, ask your doctor if he or she can help you find them out.
But genes don’t decide everything. For example, eating an unhealthy diet can keep you from growing to your full potential (潜力). Getting plenty of sleep and enough exercise will help you grow to the expected height.
It’s natural that you’re wondering how fast you should grow. There’s no perfect or right answer. Generally speaking, kids grow about 6 cm a year between age 3 and the time when they start puberty .
Your doctor will know how your growth has been going over the years. 2 cm here and 3 cm there make a little difference to the height you’re at now. How have you been growing up to this height？What other changes may your body be going through？
Don’t be amazed if you seem to have grown a lot in a very short time. Everyone has a growth spurt (高峰) during puberty. The age for starting puberty is about 10 for girls and about 11 for boys. But it can be earlier or later — between 7 and 13 for girls and 9 and 15 for boys.
You’ll usually begin to notice that you’re growing faster about a year after your body starts to show the first changes of puberty.
小题1:If you want to know how tall you should grow, _______.| A．you should have enough exercise | | B．you can ask doctors for help | | C．you should take some special medicine | | D．you can record your growth during puberty |

小题4:After reading this passage, we can explain ______.| A．how good it is to be a doctor | | B．how much sleep time we need | | C．why genes can’t decide everything | | D．what healthy diet is |

The police find most criminals (罪犯) because somebody tells them who the criminals are. They find other criminals by using science and their computers. When there is a bank robbery (抢劫), the police first look through their computers for the names of the bank robbers that they know about. Then they go and talk to any of these robbers who are not in prison (监狱). They ask them where they were when the robbery happened. If any of these people cannot give a good answer, the police will often use science to find out if one of them is the robber.
Many criminals leave something of themselves at the places of the crimes like a fingerprint or a hair. Or they take something away on their shoes or clothes, like dirt or animal hair. If they leave behind some of their blood or their hair or a piece of skin, it will have their DNA inside it.
Everyone’s DNA is different and their fingerprints are also different. So, if a criminal cuts himself during a robbery or leaves his hair, or even a small piece of skin, scientists can find out what his DNA is. The police can then ask the person they think is the robber to give them his hair or some blood and see if it has the same DNA. Many criminals are in prison today because of this kind of evidences .

What will the car be like in the future? Maybe we can sit in a car that can drive itself.
About 40 years ago, scientists from the United States started to develop self-driving cars (无人驾驶汽车). The most famous recent one was made by Google in 2009. There are cameras and radars (雷达) on the top of the car. They allow the computer in the car to draw a 3D map of the environment. Chinese scientists have also successfully developed a self-driving car. The car made a trip from Changsha to Wuhan.
Is a self-driving car safe? A recent study shows that robots make safer drivers than humans. If only 10% of cars on the street are self-driving, they will save 1,000 lives (生命) every year. If 90% of vehicles (交通工具) are self-driving, 21,700 lives will be saved a year. However, a self-driving car is expensive and each costs about $100,000. So it is impossible to be very popular in the near future.
