Which animals are smart? Your answer may be dogs, monkeys or elephants. Now there is one more animal that can be added to the list: sheep.
Scientists from Cambridge University said that sheep could be trained to identify human faces. Before testing, scientists let the sheep take a look at pictures of four famous people, including Barack Obama. Then the sheep went into a room with two computer screens. One screen showed a famous person. The sheep always walked toward the screen with the correct faces.
After discovering the sheep’s ability to recognize famous people, researchers gave them a new task. They wanted to see whether these farm animals could correctly identify the same people from different angles (角度). To their surprise, the sheep were still able to identify them, though they were a bit slower than before. Finally, the researchers wanted to know if the sheep could identify their trainers from a photo. As a result, the sheep could do this without any training.
The results show that the sheep’s face-recognition abilities are similar to those of monkeys and humans.
Face recognition is very difficult, but sheep have big brains. The researchers said it might be interesting in the future to find out whether sheep can identify different facial expressions made by humans.

Our school’s science festival just ended a few days ago. What interested me most was the car we made. It was made out of corrugated cardboard (硬纸板), but could still hold a person, as well as move.
We were excited about this idea, but we found it hard to make the car. It seemed impossible for a cardboard car to carry someone. Our physics teacher showed us a video. There was some corrugated cardboard shaped like a “V” or “W” in the video. It could hold more weight. This gave us the idea to make the car after getting the proper materials.
Because there was not much time left for us, we ha to finish it as quickly as possible. We talked about how the car should be made and how to test it. I was glad that we were able to work closely with each other. Everyone saw the work as an interesting way to relax. When the car was finally finished, we all wore a smile on our face and found that all our work had been worth it, even after spending whole afternoons working on it.
We joined the competition after we finished the car. Though we didn’t win any prizes, we found something more meaningful than success. We learned new things about physics and learned how to get along with each other.
1. The car was made out of ________.| A．thick stone | B．special glass | C．strong wood | D．corrugated cardboard |

If anyone can be called a scientific giant (巨人) after Albert Einstein, that person must be Stephen Hawking. On March 14,2018, the world-famous British scientist died at 76 in Cambridge, UK
Hawking was found to have a serious illness when he was 21. It stopped him from walking and talking. He had to sit in a wheelchair and “speak” using a computerized voice. However, his illness could not stop him from achieving great things.
He explained that the universe (宇宙) began with the Big Bang and will end in black holes. This became the basis for a lot of other research. “My goal is simple,” he once said. “It’s a complete understanding of the universe.”
Hawking also made great efforts to help others understand the universe. He wrote A Brief History of Time which has sold more than 10 million copies around the world. In the book, he explains the start and end of the universe using simple language. He also wrote books for children, like George and the Big Bang. They help kids learn about space.
Stephen Hawking was also a great father. He had three children, and he passed on three pieces of advice to them
Always keep working, because work gives purpose and meaning in life.
Always look at the stars, never look down at your feet.
If you are lucky enough, you will find love. Never throw it away.
Hawking has left us. But just as his children said after his death, Hawking’s works and spirit will live on for many years.
