Animals grow up in different ways. They have lots of lessons to learn.

    Some animals are born helpless but their mothers protect them. A newborn kangaroo is the size of a bee. She stays in her mother's safe pouch. She doesn't open her eyes for at least five months. A newborn monkey cannot walk. He is carried by his mother.

    Other baby animals can walk soon after they're born. They learn to run with their mother when danger is near. A baby zebra(斑马) can run an hour after she is born.

Some baby animals are born in a place that is safe. Other baby animals are born in the open. Baby wolves are born in large holes. A baby elephant is born on open, grassy land. Other elephants make a circle(圈) to protect her.

    Animals that drink their mothers' milk are called mammals. A mother bear's milk is fatty and rich. Baby bears need lots of fat to keep warm in winter. They have milk for six months. Baby zebras drink milk for six months or more! As baby animals grow they need solid(固体的) food. Baby lions eat what their mother can catch.

    On 15 January, 2018, International Olympic Committee (IOC) president Thomas Bach awarded the Pierre de Coubertin medal (顾拜旦奖章) to Lv Junjie, a Chinese master of Zisha, in Lausanne. Lv became the first Zisha artist to take the award. The medal was introduced in 1964 and named in honour of Pierre de Coubertin, founder of the IOC.

    Zisha is a type of clay. It has been used in Chinese pottery (陶器) since the Ming dynasty. The finished stoneware (粗陶器) is used for teaware (茶具) and other small items, and is not usually having a shiny coat. It is red or brown in colour. Lv got the prize from the IOC because of his work using Zisha to spread me Olympic spirit.

    "It's my first time stepping into the IOC headquarters," Lv said. "It has nothing to do with me. It is this traditional art of Zisha that receives such recognition from the IOC. It is because of the uniqueness (独特性) and lasting spirit of Chinese culture," he added.

    In 1966, Lv Junjie was born in Yixing, Jiangsu Province, China. His father Lv Yaochen is a famous artist in Chinese Zisha industry. Lv Junjie was influenced by his father from an early age. However, his family didn't support him to work for it at first. His mother worked as a worker in the Zisha factory all her life and knew it was hard work. At the age of 16, Lv Junjie decided to be an artist like his father. He told his father that he loved Zisha. Later he studied at a university in Singapore. After he finished school he made Zisha his career.

    The ocean is no longer a safe place for many creatures. For many years, 1 activities such as polluting and overfishing(过度捕捞) have made it 2 for many creatures to live in it. In 2015, Chile, a country in South America, tried to 3 that. It created the Nazca-Desventuradas Marine Park. It is the 4 ocean reserve in North or South America. It is about 115,000 square miles of the Pacific Ocean. That's about the 5 of the state of Arizona, USA.

    No 6 or any other kind of harmful human activity will be 7 in the waters in that area. That's good news for the sea creatures that live in that part of the Pacific Ocean. The area is 8 to many unusual creatures not found anywhere else in the world.

    2015 was a big year for protecting the world's oceans. In total, more than one million square miles of ocean were 9 protected in the year.

    Liesbeth van der Meer is a scientist at Oceana, a group working to 10 the oceans. She said Chile's new reserve was a great victory(胜利) for the world's oceans.

Sometimes a common job can make a difference. A man has been working hard at Peking University for 17 years，repairing（修理）almost 500 bikes. 

Lin Qinggang，from Xingtai，Hebei Province，he worked as a builder and sold bikes in Beijing. Then in 2017，Peking University built a small repair shop for Lin. 

In the past years，Lin's great services have won the hearts of teachers and students at Peking University. He always gets to his repair shop as early as he can. "If people come to take away their bikes and I'm not there，they will have to wait"

Students usually come over to Lin's shop to have their bikes repaired before and after lunch，so he is often busy during these hours and he has to finish his meals quickly. "I can____ have lunch on time，and usually have dinner at about 8 or 9 pm，and sometimes even at 10 pm"

"Some of my services were free，but the students still gave me money or paid more. They encouraged me to work harder，Lin said. 

Not everyone is born to be a great person. However，each of us might live a meaningful life like Lin.
