题型：不详难度：来源：
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 |
| A．童年时期 | B．婴幼儿时期 |
| C．习惯养成期 | D．生长发育期 |
| A．how the genes work in your body |
| B．how your parents’ height influence you |
| C．how you look like your parents |
| D．how you grow to a certain height |
| 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 |
| A．Your height most probably depends on how tall your parents are. |
| B．Girls’ age for starting puberty is usually earlier than that for boys’. |
| C．The features showing the first changes of puberty between boys and girls are different. |
| D．You may be amazed sometimes when you grow too fast. |

小题3:主旨大意题。阅读短文可知，这篇短文主要谈到了人如何长高的问题，故选D，你如何长到一定的高度。
小题4:细节理解题。阅读短文可知，这篇短文告诉我们身高与基因相关，但并不是决定因素，故选C，为什么基因不能决定一切。

举一反三
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 .
根据上文内容判断正 ( T ) 误( F )
小题1:Usually the police find criminals because they use their computer.
小题2:The police do not usually ask criminals who are in prison about a crime because these criminals could not have done it.
小题3:The most useful evidences that criminals leave at the places of their crimes are things with their DNA in them.
小题4:Many criminals usually take something away only on their shoes after the crimes.
小题5:The story is about a bank robbery.
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.
根据短文内容，判断下列句子正误。正确的用“A”表示，不正确的用“B”表示。
小题1:American scientists started to develop self-driving cars in 2009.
小题2:Cameras and computers are on the top of the self-driving car by Google.
小题3:In China, scientists have successfully developed a self-driving car.
小题4:The more self-driving cars there are on the street, the fewer traffic deaths there will be.
小题5:The self-driving cars will be very popular in the near future.
The big cheetah is named Jolie, after the film star Angelina Jolie. 小题1: She can often be found eating from the kitchen table, taking a short sleep on the sofa, or even sleeping on Lucy and Jeff’s bed. The big cat also sleeps and plays with the Browns’ other pet, the more usual one — a sheepdog (牧羊犬). 小题2:
Having a cheetah as a pet is unusual. At first, Mrs Brown wasn’t willing to keep a cheetah as a pet. She said, “ 小题3: But we are now happy that we did it — she is part of the family.”
Just like her name, four-year-old Jolie has achieved a celebrity status (名人地位) in the Browns’ hometown. Fans often come to their home to take pictures of her. 小题4:
However, a cheetah is always a cheetah. 小题5: “She makes a lot of mess in the house, urinating (小便) everywhere and chewing everything. It’s her wild instincts (本能),” said Mrs Brown.
There might be some problems of having a cheetah as a pet in the house, but some unusual fun must also be waiting ahead.
Why? It is because the corridor was built with special kinetic (动能的) tiles. When students jump on the tiles, electricity will be generated ( 产生). After one year, the electricity generated from the tiles can fully charge 853 mobile phones or power(供电) an electric car to drive seven miles. It’s amazing, isn’t it?
The corridor tiles are really a brilliant invention. Students can not only play on the corridor,but also help power the lights in their school corridors and other devices ( 设备) in their classrooms. Besides, this is a good way to teach students to be creative. They will be inspired to be scientists, inventors and engineers in the future to find clean energy for all humans.
The inventor of the magic corridor tiles is Laurence Kemball-Cook. He was once a student in this school. Now, he is CEO of his own company. The corridor tiles are not Laurence’s only invention. He has also invented a special dance floor, which can be used at music festivals. It allows dancers to charge their mobile phones while they are dancing on the dance floor.

A. Because the corridor tiles are expensive.
B. Because the teachers ask them to do that.
C. Because the corridor was built with special tiles.
小题2:After one year, the electricity generated from the tiles can provide enough energy for _______.
A. over 800 mobile phones
B. all the lights of the school
C. an electric car to drive70 miles

Write note cards. Write main ideas on your cards. Don’t write details. Put in some fun facts, questions, and other activities on the cards to share with the class. Don’t look at your note cards for a long time while speaking. If necessary, you’re only going to want to have a quick look at the card for information, not read every last word.
Smile at your class. When it comes time to speak, there’s nothing that draws your class into your speech than a good old-fashioned smile. Be happy, because you’re about to teach your class something they didn’t know before. Studies have shown that smiles are infections. That means once you smile, it’s hard for everyone else not to smile. So if you want your speech to go off well, smile. That’ll make everyone smile and maybe those smiles will make you actually smile.
Make eye contact. Nothing is more boring than listening to a speaker who looks at the floor or at note cards. Relax. Your class is made up of your friends and you talk to them all the time. Talk the same way now. have a look at every person in the classroom at least once. That way, everyone will feel like you’re communicating with them. Also, you’ll look like you know what you’re talking about.
Use hand motions. Move your hands along as you talk, using them to express your key points and keep the class interested. It will also lead your nervous energy into a better place.
