It has been forty years since China's Reform and Opening-up(改革开放). Let's see how China has changed through the years.

    1978—1988: New Look

    In a 1978 Japanese documentary(记录片) China's New Look, there was a scene showing Chinese people' life back then. In front of an old-fashioned TV set, some Shanghainese gathered around to watch a TV show. In 1981, only one out of every 170 city families in China had a color TV.

    1988—1998:         

    In October 1990, the first McDonald's on the Chinese mainland opened for business in Shenzhen. It quickly became the hottest tourist spot(旅游景点). "Many Chinese customers waited in line and shouted to the shop assistant, "I want 10 Big Macs," recalled a waiter at McDonald' s at that time.

    1998—2008: Here Comes WTO

    For many Chinese, the year 2001 was very unforgettable. It marked the start of a new millennium(一千年) and led to a whole new era(时代) as China joined the World Trade Organization(WTO). From 2001 to 2017, China's average(平均) growth of the import(进口) of goods and services was more than twice the world's average.

    2008—2018：New Beginning

    Shanghai, a city of long-time business culture, is always a step ahead in China's foreign trade. With the successful hosting of China's first import expo(展览会) in November 2018, the city went on to develop China's import business. The expo will be remembered as a new beginning for China's import history.

    A Chinese song could be heard in a classroom in Sana, the capital of Yemen(也门), where around 20 Chinese-learning schoolchildren were singing

    "I love to learn the Chinese language because it is very nice, important and I want to travel to China to complete my studies there," Karim al-Areqi, a student of the private Languages Model School in Sanaa, told Xinhua.

    Teacher Mohammed al-Ansi, who learnt the language in China and received a university degree, stressed(强调）the importance of learning the Chinese language. "It is the language of the future and it is necessary for all people to get advantages from the great development in China," he said.

    Like many other private elementary and secondary schools in Yemen, the Chinese language is a basic part of the Languages Model School's courses, where the students study Chinese as actively as math and science subjects. "In teaching the Chinese language, I succeeded in educating students in a simple way that fits everyone," al-Ansi said proudly, stressing that teaching Chinese has changed his life without doubt.

    Al-Ansi expects that Yemen and China will work together to set up centers and schools for teaching the Chinese language in Yemen so that many young Yemenis can learn. "I hope that a branch of the Confucius (孔子学院),could be built in Yemen to teach the language and spread the Chinese culture to many years who are interested in learning the Chinese culture and language," he said. see that learning a foreign language may open a way of hope to a new life, such as getting ,more money and paving(铺平)the way to a bright future in the country that has experienced war for almost five years,

Dorothy lived with her uncle Henry and aunt Em who were both farmers.Their house had only four walls，a floor and a small space under the floor to protect them from powerful winds.The house was in the middle of poor land with strong sunlight and few plants.Aunt Em used to be young and cheerful，but the sun and wind had taken away her happiness.Uncle Henry also looked serious and strict.Only Toto，could bring laughter into Dorothy's life.

One day，they heard low sounds of wind from both the north and the south.Uncle Henry realized a strong wind was coming.He rushed to protect the animals while Aunt Em hurried Dorothy to the basement.Suddenly，the house began to rock and rise to the air.In the center，but Dorothy found herself riding safely on the rising house.

Frightened，Toto ran around the room until Dorothy caught him and protected him from falling through the open door.She closed it carefully to avoid further danger.As hours passed，Dorothy slowly got over her fear.She finally fell asleep on her bed with Toto by her side.The wind had set Dorothy's house down gently in a beautiful country.

As she looked around, she saw green grass, fruitful trees, and colourful flowers.Birds with special feathers sang and flew around.As she stood enjoying the beautiful views, a group of strangely dressed people came near. They wore round hats that rose to a small point a foot above their heads. Three men were dressed in blue, and a little woman wore a white dress. They stopped and discussed in a low voice, as if afraid to come farther.

You're in summer heat now, but in Australia some animals are feeling cold in winter and trying to get warm by bathing in the sun. A crocodile(鳄鱼) on the Ross River in Australia is just doing this with a turtle(乌龟) on his back. 

It seems the turtle is a friend of the crocodile. But in fact, the truth is that the crocodile feels    so cold that he gets out of the water, trying to get warm by bathing in the sun instead of wanting to eat other animals. 

Kana Wiblen, who lives in Townsville, Australia, found the 2-meter-long crocodile, known as Ross the Croe, with a turtle friend on his back. 

"We were just looking for some turtles when some other people in the area said that there was a crocodile nearby, so we went to have a look, " Mr Wiblen said. "When we found him, he had a turtle on his back, so I quickly took a photo before the turtle jumped off his back and went back in the water. "

"About five minutes after the turtle jumped in the water, we were about to leave when he came back up again, and with another turtle! They both sat next to each other on the back of the crocodile. I don't know why the turtle chose to ride on the back of a crocodile, but I'm sure that he was not afraid at all. Brave turtles, I must say, " he added. 

So what do you think of the amazing friendship between a turtle and a crocodile?
