Modern inventions make our life easier and more interesting than before. Let’s take a look at some inventions.
A new kind of enzyme(酶) Scientists in Britain and the United States have found a new kind of enzyme that eats plastics. With its help, plastics can be turned into smaller parts and go away quickly. It can stop plastics from being burned everywhere. Scientists believe that it can solve the problem of plastic pollution in the future. |
Social robot Can robots talk to us like humans? Jibo, a robot made in US, can talk with you. The robot has a big, round head and a big body with no eyes or mouth. It uses animated icons (动画图标) to show emotions(情绪). It just seems like a real human. Right now, Jibo can only do some easy things, like taking photos and reading news to you. But it may learn to do new things in the future. |
Spark Spark is a new drone(无人驾驶飞机) made by a Chinese company in Shenzhen. It can help people take photos and videos. Spark might be the smallest drone ever made. When folded, it is as small as a Coke can. The coolest part is that users can control the small drone just by using hand gestures. For example, if you wave your hand from left to right, the drone will fly in the same way. When you want it to land you just put your hand out. The drone will come to you and land on your hand. |

【推荐1】Have you ever seen a solar panel (太阳能电池板) in your neighborhood? Solar panels take energy from the sun and turn it into electricity. Over the past ten years, the price of solar panels has gone down greatly. In many parts of the world, solar energy is now the cheapest form of electricity. More and more people have started using solar energy to power (给……供电) their homes.
However, solar panels also have their problems. They stop working at night and on rainy days. Is it possible to make them produce electricity all of the time?
Scientists at Suzhou University, China, have invented a new solar panel now. It can produce electricity not only from solar energy, but also from falling rain. When a raindrop falls on the solar panel and then rolls (滚动) down, it creates friction (摩擦力) on the surface of the panel, which can then be turned into electricity.
Sun Baoquan is one of the inventors. “Our new invention can produce electricity in any weather during the day,” he says. “It can even provide electricity at night if there is rain.”
The solar panel, however, does not make much electricity. So Baoquan is still working hard to improve it. The scientist also wants to make solar panels more flexible, which are as soft as clothing.
The field of solar energy is developing fast. Scientist around the world have been improving solar panels. Some have been working on ways to join solar panels and wind power together. Some have been trying to use sunlight to produce liquid and gas fuels (液体和气体燃料).
1. ________ is now the cheapest form of electricity in many parts of the world.A.Oil energy | B.Water energy | C.Solar energy | D.Wind energy |
A.the price of them is rising | B.they make too much electricity |
C.they can’t work all of the time | D.they can hardly power people’s homes |
A.the new solar panel is more useful |
B.the new solar panel is larger than a common one |
C.the new solar panel produces more electricity on rainy days |
D.the new solar panel can’t produce electricity day and night |
A.柔软的 | B.光滑的 | C.复杂的 | D.坚硬的 |

No one knows who invented the button(扣子). It might have appeared as early as 2,000 BC. When it first started, it was just something beautiful sewn(缝上) onto your clothes. What is more important than the button is the buttonhole(扣眼). About 3,000 years later, someone finally invented the buttonhole, and buttons were suddenly useful.
Before buttons, clothes were bigger—they had no fixed shapes. Because of the buttonhole, the fashion moved closer to the body when we discovered uses for the button. It was the very way to make clothes fit well for the body. People feel safer like it’s never going to open.
The size of the button depends on its use. Shirt buttons are generally small, and they are close to each other, while coat buttons are larger and farther apart. For example, the standard buttons of men’s shirts are 10.16 mm and of suit jackets are 20.32 mm.
In modern clothing and fashion design, buttons are mostly made of plastic but also may be made of metal or wood. Buttons can also be used on wallets and bags. They can be shown as examples of works of art.
A button can be used for a long time. It’s one of the most lasting designs in history, because it really works to make people feel safer. Zippers easily break and are hard to fix. However, if a button breaks, you just need to sew another on. And you can sew more buttons if needed.
The pattern of a button hasn’t changed much since the Middle Ages. It’s not only one of the most useful inventions, but it plays an important role in the development of clothes. Up to now, we can still see its influence on the clothes design. If you’re wearing the clothes with buttons, take a look at the position of buttons on it. If you’re a man, the buttons would likely be on the right side, but for a woman, the buttons are usually found on the left.
1. Buttons were suddenly useful ________.A.after about 3,000 BC |
B.after buttonholes were invented |
C.when buttons appeared in 2,000 BC |
A.Shirt buttons are bigger than coat buttons. |
B.Coat buttons are close to each other. |
C.Suit jacket buttons are bigger than shirt buttons. |
A.The influence of buttons never disappears. |
B.Buttons are not so easy to fix as zippers. |
C.People see buttonholes as works of art. |
A.Life | B.Travel | C.Environment |

Pandas live in the forests and mountains of Southwest China. They mainly live on bamboo, and each panda needs to eat a lot of bamboo every day. The area of bamboo is becoming smaller for many different reasons, so pandas have less and less land to live on. Pandas don’t have many babies, and baby pandas often die. The situation is becoming very serious.
Our government is working hard to save pandas. There are more than 30 nature reserves to protect pandas but these are not enough. The government has made a new plan to help pandas. The nature reserves will be bigger and the bamboo will grow better. Then the pandas will have enough food to eat and enough places to live in. Pandas born in the zoos may go back to live in the nature reserves.
Most people love pandas. The panda is one of the best-known animals in the world. It is the symbol for the World Wide Fund for Nature. The WWF works to protect all animals in danger, so the panda has become the symbol of all animals in danger. There is still a long way to go to save the panda. Think of other animals in danger such as tigers ,whales, turtles and elephant—we need to save the panda, and we need to save them, too.

Have you heard of the video—sharing app Douyin? It's quite popular these days. There are some interesting videos on it. They are very short—— from 15 to 30 seconds(秒). I like watching them. But there are some bad things about the app, too.
First, it can take up too much of our time. You can easily become addicted(上瘾的) to it. Once, I watched videos for nearly a whole afternoon. I forgot to do my homework. It was a waste(浪费) of time.

My mother realized that she was poor at English. When I was fifteen, she used to have me call people on phone to pretend I was she. I was made to ask for information or even to shout at people who had been rude to her. One time I had to call her stockbroker(股票经纪人). I said in an adolescent(青少年的) voice that was not very certain, “This is Mrs. Tan.” My mother was standing beside me saying, “Why he doesn’t send me check, already two weeks late.” And then, in perfect English I said: “I’m getting rather worried. You agreed to send the check two weeks ago, but it hasn’t arrived.” My mother then talked more loudly. “What he want? I come to New York to tell him in front of his boss.” And so I turned to the stockbroker again, “I can’t accept any more excuse. If I don’t receive the check immediately, I am going to have to speak to your manager when I am in New York next week.”
The next week we ended up in New York. While I was sitting there red-faced, my mother, the real Mrs. Tan, was shouting to his boss in her broken English.
When I was a teenager, my mother’s broken English embarrassed(令人尴尬) me. But now, I see it differently. To me, my mother’s English is perfectly clear, perfectly natural. It is my mother tongue. Her language, as I hear it, is vivid, direct, and full of observation and wisdom. It was the language that helped me see things, express ideas, and
