You know how much your telephone has changed over the past 10 years? Your car will change even more than that in the next 10 years. One of the biggest changes is that cars will drive themselves.

    “We certainly have the technology for it now.”says Andrew Poliak of automotive（机动车辆的）technology supplier QNX.“We expect self-driving cars to be a mainstream thing between 2020 and 2025.”

    The American company Google has been working on self-driving cars for years. These cars are already on the roads in the United States and are truly self-driving. They have to steering wheels（方向盘）or pedals（踏板）. Last week, the police ordered one of Google's cars to stop for driving too slowly on a public road. The car was not breaking any law, so no one was punished.

    Another American company, Tesla, added an “Autopilot” feature to its cars last month. With the Autopilot turned on, the vehicle drives itself. The car will speed up, slow down, brake and drive by itself. You can take over driving any time by turning the steering wheel or touching a pedal. The car uses sensors（感应器）to know when driveway changing is safe and whether it should speed up or slow down.

    Tesla Autopilot is made for cross-country driving. It keeps you in the driveway and helps you avoid hitting other cars. It does not work well on local roads, for it will not stop at a red light or stop sign.

    Reporter Carolyn Nicander Mohr tried the Autopilot feature of a Tesla earlier this month. She had a hard time trusting the car to do what it should do. She thought about disabling the Autopilot feature many times during her trip. She wanted to take control at every bend in the road and hit the brake when the car in front of her slowed down. Yet the car drove perfectly.

    Other companies are working on self-driving cars, too. Marcedes-Benz, Audi, BMW. Volvo and Toyota all have plans for such vehicles.

Jacaranda is from South America and was introduced to Kunming in the 1980s. Each May, the city is in purple as the trees are full of the flowers, attracting a number of visitors. Kunming is known as the "kingdom of flowers". In recent years, the jacaranda has been helping further increasing the popularity of the city.

I spent my college time in Kunming ten years ago. So I still have feelings for the city. Back then, we couldn't see these flowers. They are suddenly famous in recent years. They're really beautiful, and I feel happy to see the city improving.

The local government is also taking the chance to organize many activities to develop the tourism. During National Labour Day holiday, the visitors there almost doubled compared to the last year. You can buy all kinds of popular local foods and cultural and creative products here at this special market. This ice cream in the shape of jacaranda flowers is just one of the most popular products here. During weekends there are also concerts to greet visitors. Now, special sightseeing buses are also in service to help people better enjoy the beautiful flowers. It's a different experience. We just walked around but now we can take the bus to enjoy the flowers. It feels great, and we can take many different kinds of pictures.

The local government says they will further make good use of the value of the flowers by expanding planting areas and holding more creative activities.

Great writers have one thing in common—they read a lot. {#blank#}1{#/blank#} Here is some advice.

Develop the reading habit. You can write down your goal (目标), for example, read for 30 minutes every day, and put it up somewhere you can see it. {#blank#}2{#/blank#}

Take your book with you. When you go on the road, always take your book. {#blank#}3{#/blank#} But at the tenth time, you'll be glad you brought the book.

Read books of great writers. "Great writers" don't only mean writers like Shakespeare. People who can create great characters, reach into your heart and open up new worlds for you are all great writers for you.

 {#blank#}4{#/blank#} Reading is more than just learning. It's about joy. If a book makes you bored, put it down and do something you enjoy more.

①Animals are important and they are our friends. But some of them are in danger now. What can we do to help save them?

②Don't eat meat. Some of us like to eat meat because it is delicious. But do you know some meat comes from endangered(濒危的) animals? To save animals, please choose more vegetables and fruit to eat instead of meat. And it's healthy for us, too. 

③Don't wear clothes made of fur(皮毛). Sometimes people also kill animals for fur. But if we don't buy or wear clothes made of fur, people will no longer kill them. 

④Donate(捐赠) money to Animal Helper(AH). AH always does everything to help save animals. But it is often short of money. So please save some money and give it away to AH to help animals. 

⑤Tell people it's important to save animals. Not all people are aware of their importance to humans and why we must save them. So why not tell people around us that it's important to save animals? It's helpful.
