2 . ①Since the first man looked up at the flying birds, countless successes have been achieved on the way up to the sky. From the stones thrown into the air to airships of all kinds, pioneers of humans never failed to let their imagination run wild.
②Stories of pioneers go back to centuries ago.
③Kite flying in China dates back to the 5th century BC and is thought to be the earliest example of man-made flight.
④From the 3rd century BC, the sky lantern (灯笼) was known in China. Many people believe that it was invented by Zhuge Liang in the war. Some say he wrote a message on a sky lantern for help, while others believe sky lanterns were used to drive the enemies away.
⑤Whichever is true, humans have never stopped, and they never will. In modern times, new fields are being explored (探索).
⑥In 1993, the world’s largest hot air airship was built. The AS-300 carried an underslung raft (悬挂式木筏). It allowed a team of French scientists to carry out their treetop researches without too much harm to the rain forest.
⑦On May 15, 2022, Chinese scientists sent up the latest model of “Jimu No.1”, China’s self-developed airship, to collect weather information on the Qinghai-Tibet Plateau.
⑧The airship would work at a world-record altitude (海拔) of 9,032 meters. It was the first time an airship of its size had reached this height, even higher than that of the 8,849-meter-tall Mount Qomolangma, the highest mountain in the world.

3 . PowerPoint Presentations (PPT) are taking the place of writing on the blackboard with chalk. Someday, will robots take the place of human teachers?
In Japan, a robot is going to enter classrooms to help teachers. Last week the Japanese company Honda Motor Co. showed the public its robot at a Tokyo museum. The robot’s name is Asimo. Students will see Asimo in science classes and learn the wonders of science.
Asimo is 130 centimetres tall with a round head. It can jog, walk up stairs and wave. It can also avoid things on its way and have simple talks with you. Asimo is an experienced worker for humans. It has worked as a guide in showrooms. But this will be the first time it works as a teaching assistant in classrooms and in formal teaching!
How will Asimo help in class? A teacher explained the way Asimo works to students in last week’s show. Asimo has sensors (感应器) inside its body to keep its balance.
The smart Asimo tilted (倾斜) its body when it stood on a shaking platform (平台). Asimo kept its balance. But a wooden person beside Asimo fell (See the above picture).
When you walk, you pass your weight from the heel to the toe. The Japanese teacher explained this with Asimo at the museum. He moved the robot in slow move. Asimo made learning science more interesting for students!
Asimo will soon help teach thousands of primary students and junior high schools in two Japanese cities. Hopefully, robot teachers will arrive at our classrooms in China one day.

How has technology changed the way we watch TV?
Watching TV shows has become the most popular activity. A survey points out that people have many ways to watch shows besides cable TV. They include smart phones, computers, and tablets. Technology has not only changed where but also how we watch TV. Streaming(流媒体) networks have helped viewers watch their favorite shows when it’s most convenient for them.
Binge-watching(刷剧) has become a new trend. Without having to wait for next week’s episode(集), viewers can watch the whole season in a day, or at whatever pace(速度) they choose. In the US, content(内容) providers also release a choose-your-own-adventure movie, where your choices can affect(影响) how the story ends, an idea not possible before with traditional TV.

6 . Someday in the future we may not need to have money in our pockets. Is life easier when people don’t need to carry any money? Maybe in the future each of us will have only one small credit card. We will use it instead of money to buy all the things.
Of course we may still have some of the same problems with cards we now have with money. For example, we lose money from time to time. Maybe we will lose the cards. Maybe someone will take the cards. Someone may even make a card that looks like our cards. Since we can’t buy anything without our cards, the credit cards may be no better than money.
Is there something easier to use than credit cards? Each of us has a thumbprint(拇指指纹). No two thumbprints are the same. Maybe someday the government will keep people’s thumbprints with a number. When you want to buy something, you will put your thumb on a machine or a computer. Each store will posses one. Everyone’s thumbprints will be in the computer. It will be difficult to lose our thumbprints! It will be difficult for someone to steal it or to make one like it.

7 . What will our life be like in 50 years? No one knows the answer exactly (确切地), but we are sure that it will be very different from the life today. My brother Jim Green makes some predictions. Here are some of his ideas.
First, people will have less work to do, and robots will do most work. People will use robots to make cars, do the housework, look after sick people and teach students. People will spend most of their time playing sports and traveling. So people will become stronger and healthier, and they will live to be about 200 years old.
Second, cars will become very small and computers will control (控制) their speed. So there will be fewer accidents on the road. Planes will be very popular and most people would like to take them to travel.
Third, people will be able to live in the sea, on the moon or on Mars. The earth won’t be crowded or noisy. So there will be more space for people to plant trees. There will be less pollution, and the air will become much fresher.
Finally, water shortage will become one of the most serious problems. If people don’t save water now, there will be water wars in 50 years.
