3 . Galaxy saw a man and a woman who communicated with sign language at the train station when she was on the way home one evening. She noticed that the woman was asking the man for direction. He told her that he did not know. Galaxy decided to help them. She had learned sign language when she served as a volunteer in the deaf and mute (聋哑的) school. Then she showed the woman the direction and left her email address to them in case they needed her help later.

She received an email from that man the next day. Kazrim was his name. Galaxy replied his mail sincerely. They both started chatting online soon after and began seeing each other. Although they only communicated with the sign language, it never bothered her.

Galaxy grew fond of him gradually. Obviously, Kazrim was the same too. He presented Galaxy with a bunch of sunflowers and asked her sincerely, “Are you willing to be my girlfriend? Galaxy was pleasantly surprised. She requested him to give her some time to persuade her parents. As she had expected, her parents were furious after they had learned of their love story. Galaxy explained, “Kazrim is an excellent and a very optimistic person. He has a very positive attitude towards life and work. He cares for others always. He is 100% better than the normal. Moreover, the mute is still a human. He should have a perfect and wonderful love.”

Her parents asked to see him then. The very worried Galaxy took Kazrim home a few days later. When they were on the train, Kazrim told her, “I'm going to tell your parents that I'll be looking after you well with all my life!” Galaxy was deeply moved. As soon as they had entered the house, Galaxy introduced him to her parents. She said, “This is Kazrim.” Just right after her speech, an unbelievable thing happened. Kazrim threw the gift away and held her in his arms tightly. He said. “You CAN talk?” It was the same question that Galaxy wanted to ask, too. The four people were shocked all of a sudden. As a matter of fact, Kazrim always believed that Galaxy was a mute and he still fell in love with her deeply.

4 . Scientists are urging that deep sea metal mining should be stopped temporarily. They warn in a report that it can cause severe damaging effects on Pacific Ocean areas.

The recently-released report examined more than 250 published studies on deep-sea mining. The research was examined by the Deep Sea Mining Campaign — a collection of not-for profit organizations. The report centers on mining activities related to small metallic particles(金属颗粒)，called nodules, found on the seabed. The material can contain different metals. Increasing demand for these metals has led to a rise in deep-sea mining operations. The metals are commonly used in battery manufacturing and other technology products.

However, the scientists warn that mining for these nodules will cause irreversible(不可逆的) damage to an ocean already under pressure. The operations will affect areas across the South Pacific, including the nations of Kiribati, the Cook Islands, Nauru, Tonga and Papua New Guinea.

The report notes that a moratorium is the only responsible way to move forward until certain conditions surrounding deep-sea mining can be met. The scientists are calling for additional study to fully understand the environmental, social and economic risks.

Andrew Chin is the report's lead researcher. He says in a statement that nodule mining will likely result in the loss of sea life and cause damage to deep seabeds for thousands of years. He adds that the operations can put people at risk who depend on the ocean and its continued health.

A company planning to be one of the first to carry out mining operations in the area is Canada's DeepGreen, which aims to begin by 2024. It seeks to mine metallic nodules to be used in power systems for electric vehicles. DeepGreen Chief Executive Officer Gerard Barron defended the company's plans in reaction to the report. He said deep-sea mining offered the best alternative to surface mining, which has long history of pollution and destroying forests and wildlife.

7 . The food we eat seems to have a great effect on our health. Although science has made big steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of human illness is related to food and forty percent of cancer is related to food as well. That food is related to illness is not a new discovery. In 1945, some researchers realized that things commonly used to keep colour in meats and other food additives（添加剂）caused cancer.

Yet, these additives remain in our food, and it is difficult to know which things on the wrappings（包装）of foods are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to their animals, and because of this, penicillin has been found in the milk of cows. Sometimes similar tings are supplied to animals not for their health, but just to make a profit.

The farmers are simply trying to fatten the animals in order to get a higher price on the market. Although some countries have tried to control such things, the practice continues.

8 . Inside a brightly-lit classroom, around 20 schoolchildren are singing the Chinese national anthem. That song is followed by another tune in Chinese—one typically sung during the Lunar New Year. But this scene is not taking place in a Chinese school but at Lakewood Premier school, thousands of kilometers away in Nairobi(内罗比). Here, schoolchildren are learning Mandarin, a language spoken by nearly 1 billion people almost 8,000 kilometers away from their home. More will join their ranks in 2020 when Mandarin will be officially taught in all Kenyan schools alongside French, Arabic and German, which are already on the curriculum.

Sandra Wanjiru, 13, is one of hundreds of African schoolchildren who are increasingly skilled in the Chinese language. Lakewood Premier School, where Wanjiru studies, has begun the program a year early to give its pupils a head start. "I chose to learn Chinese first not only because it's interesting to learn a foreign language but also because I would want to travel and do business in China," said Wanjiru.

Julius Jwan, CEO of the Kenya Institute of Curriculum Development (KICD) told Chinese state-owned Chinese news agency Xinhua： "The place of China in the world economy has also grown to be so strong that Kenya stands to benefit if its citizens can understand Mandarin. " China has become increasingly powerful across Africa over the past two decades. Through President Xi Jinping's flagship Belt and Road Initiative, China has loaned money to African countries to build highways, dams, stadiums and airports.

Henry Adramunguni, a specialist at Uganda's National Curriculum(课程)Development Centre, said Mandarin was included in the curriculum because it is one of the United Nations' languages of work. "We want to give the opportunity for our young Ugandans to have access to jobs, education and business beyond our borders. That's why we've given them this opportunity to learn Chinese," he said,
