Jane Goodall is a famous scientist. For more than 40 years, Goodall lived mostly in Tanzania in East Africa. She studied chimpanzees.

As a young child, Jane Goodall was interested in animals. She grew up in the English countryside and was always climbing trees or riding horses.

When Jane was 23, she got a chance to go to Africa. Even though she had never been to college, she got a job with a famous scientist named Louis Leakey.

On July 16, 1960, she began her exploration. At first, the chimpanzees ran away from Jane. But as time went by, they liked staying with her.

Every day, Jane would follow the chimpanzees, taking notes on their behavior. She learned many new things about chimpanzees. She watched how a chimpanzees made a tool. She learned how some chimpanzees became good leaders. She watched animals get angry and get upset. She wrote everything down so others would understand animals as she did. She learned that if you pay really close attention(关心) to animals, you will understand what they are “saying”.

Isaac Newton was an important scientist who is famous for his work on gravity (重力) and light. Newton was born on 25th December, 1642 on a farm in Lincolnshire. He lived with his grandmother before starting school.

His mother wanted him to become a farmer. However, Newton didn’t believe that this was the best job for him. Newton moved to Cambridge in 1661 to go to university. He soon became interested in the new ideas about science which were becoming popular. He wanted to carry out experiments (实验) to find new and different ways of explaining the world around him.

In 1666, many people in Cambridge were becoming ill with the plague. Newton moved back home until it was safe to return to the city. He carried out lots of experiments and he made his important discoveries while he was living on the family farm in Lincolnshire. He found that white light is made up of many colors called a spectrum (光谱).

There is a famous story which says that Newton discovered gravity when an apple fell from a tree and landed on his head. He described his ideas by using the three laws of motion (运动) which explained how and why all objects move.

On May 22,2021, people in China and around the world felt sad. China’s “Father of Hybrid Rice”—Yuan Longping passed away at 91 on this day.

Yuan spent his life researching hybrid rice, which ended hunger for millions of people not only in China, but around the world. Hybrid rice is grown in about 57 per cent of China’s rice fields. It feeds more than 80 million people a year. It is also grown in over 40 countries, including India, the USA, Brazil, ete.

Yuan grew up in a time of war and famine (饥荒). Getting enough to eat was a serious problem in China at that time. After he finished high school, he decided to study agriculture. After seeing many people die of hunger during a serious famine, he decided to study hybrid rice.

In 1973, he succeeded in growing the world’s first high-yield (高产的) hybrid rice. It could reach a yield of over 500 kg per mu (亩).

In 2019, he was awarded the Medal of the Republic, China’s highest state honour. In 2020, hybrid rice achieved 1500 kilograms per mu in two growing seasons, setting a new world record.

Yuan once said he had two dreams. One was to enjoy the shade under rice crops that were taller than men. The other was that hybrid rice would be grown all over the world. I think his dreams might come true one day.
