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.

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

B. forced
C. trained

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.

One day, his grandpa said to him, “Mario, I know that you don’t have as many friends as you think. Many of them are not true to you.”
Mario thought maybe his grandpa was right. However, he wasn’t sure how he could test whether his schoolmates were real friends or not, so he asked his grandpa. The old man answered, “I have just exactly what you need. It’s in my room. Wait a minute.” The old man left, soon returning as if(好像) carrying something in his hand, but Mario could see nothing there.
“Take it. It’s a very special chair. Because it’s invisible, it will be hard for you to sit on it. However, if you manage to sit on it, you can use the chair’s magic power（力量） to tell who your real friends are.”
Mario took the strange invisible chair to school. At break time he asked everyone to form a circle, and he put himself in the middle, with his chair.
“Nobody move. You’re about to see something amazing，” said Mario. Then he tried sitting on the chair. Having difficulty seeing it, he missed and fell to the ground. Everyone had a pretty good laugh. “Wait, wait,” said Mario, making another try. But again he missed the seat.
Mario didn’t give up. He kept trying to sit on the magic chair. Finally, he did it. This time he felt himself in mid-air.
Then he experienced the magic that his grandpa had been talking about. Looking around, Mario saw George, Lucas and Diana holding him up, so he wouldn’t fall. But some schoolmates whom he had regarded as friends had done nothing but made fun of him. Mario was quite thankful to his grandpa, who helped him test who his true friends were.
