The famous scientist and thinker, Charles Darwin, was born on February 12, 1809 in England. As a boy，Charles liked to go for walks in the fields and forests. He enjoyed watching nature，and comparing what he saw with everything he had read in science books. He also liked collecting very much. He collected many things: birds，eggs，stones and leaves.

At sixteen Darwin was sent to Edinburgh University to become a doctor. But he was interested in the history of nature.

Then he was sent to study in Cambridge University. There he studied until 1831.

Some time later he heard that the ship Beagle was going on a trip to South America and wanted a scientist. His teacher advised him to go. So when the Beagle left England in December, 1831, Darwin was on it.

The trip lasted almost five years. Darwin saw many new plants and animals. He collected all kinds of plants.

In 1842 Darwin went to live in Kent，and there he continued his studies of change in nature. Darwin understood that plants and animals are not always the same，and that they really change.

By 1859 Darwin had finished his famous book The Origin of Species.

In 1871 Darwin wrote ano ther important book The Theory of Evolution.

Darwin continued his studies in science until he died in 1882.

    We were on a visit to Monkey Island. Jim thought we should try water skiing(滑水).

    We can get a boat and ski at Monkey Island.

   Don't go water skiing near Monkey Island today,” said the woman standing near the boats. “There might be sharks（鲨鱼） in the water.”

    “I don't think so.” said Jim who thought he knew everything.

    “I wouldn't go water skiing in the sea near Monkey Island today,” said the man with the woman. “They saw sharks in the water yesterday.”

    “The sharks won't hurt me,” said Jim with a big smile on his face.

      Another man getting out of a boat said, “I'm sure we just saw a shark in the water a few minutes ago.”

    “Don't worry about me,” said Jim. “I don't worry about sharks.”

    Jim and his two friends, Bill and Bruce pushed the boat into the water. Jim was driving the boat. He drove very fast and sprayed water on everyone standing near the boat.

    Jim drove the boat to the middle of the sea near Monkey Island. Everyone could see him and the boat. He wanted to show everyone how well he could water ski.

    “You drive the boat, Bill,” Jim said. “Bruce, you watch me and the rope while I water ski.”

    “What about the sharks?” asked Bill.

    “Forget about the sharks,” said Jim. “I'm not afraid of sharks.”

    Jim got into the water. He was putting his feet in the water skis. Then Jim felt something large and hard touch his leg as it swam past him. Suddenly, a brown fin(鳍) moved through the water towards Jim.

    Later, when Bill and Bruce stopped laughing, they said, “We never saw anyone move so fast! You were running on top of the water to get back in the boat! You even left the water skis in the water.

    “There it is again! Shark! Shark!” cried Jim.

Everyone laughed—even the people standing on shore.

    The dolphin（海豚） came to surface again, took a deep breath, smiled at Jim and went back down into the deep water.

Because of the COVID -19, many zoos are having hard time. Luckily, there are new ways for them\ to raise money, such as having animal shows online, selling cultural products (文化产品), making animal stars and adopting animals online (云认养) .

For Nanjing Hongshan Forest Zoo, online adoption is one of the ways to get help to getthrough hard times. People from all over the world can pay to adopt their favourite animals. The zoo will use the money to buy food for its animals and pay for their medical care. If someone adopts animal, they can get a certificate(证书) and learn about the animal's daily life online. They can go to the zoo for free, have the chance to feed the animal and clean its living space.

Animals like elephants, golden monkeys, koalas and tigers are all on the adoptioa list. Each animal has its own introduction. You can see its photo and know about its age and living baits(生活习惯).

Adopting animals online makes people think about how a zoo works. Modern zoos are no longer places for visitors to see animals but places to teach people how to protect animals.

Look!This is our classroom.It is very big and clean.It has four big windows.We're having an English class.There are 22 girls and 28 boys in our class.Everyone has a desk and a chair.They are all new.We look after them very well.In our classroom there are two blackboards.One is for the teacher and the other is for students.We can see some pictures on the board.The walls look very white.On them we can see two maps，the map of China and the map of the world（世界）.

In the morning the students come to school very early，and the teachers come to school early，too.We have four lessons in the morning and two in the afternoon.We like our lessons very much.We like our class and our classroom.We also love our teachers.
