Why is the sea salt? Long before we discovered scientific ways of thinking about it, we explained it in a story. Even though the answer isn’t scientific, it holds some other truth in it — especially about the human heart.
Long ago, a poor old couple lived on the coast. One day, an old storyteller came to their village. The old couple gave him a meal. In return, he gave them a coffee mill (磨粉机) and said, “Say, ‘Mill, please grind (磨粉)’,” and it’ll make whatever you want, to stop it, say ‘Mill, please cease (停止) grinding’.”
Soon the old couple had a much better life. They’d been happy people, and they didn’t need much more. But the young couple next door were never satisfied. When they saw the old couple wearing good clothes and buying good food, they burnt with envy (羡慕). So one day, the young husband went to the old couple’s house secretly and heard, “Mill, please grind hot chocolate!” He was surprised to see it coming out.
Then the young couple stole the mill from the old couple. With it, they rode a horse and set off down the coast, where no one would know them. Along the way, the husband showed proudly and asked, “What do you want it to make?” “Oh. I don’t know. Why not salt?” the wife said. “Mill, please grind salt!” he said. “It works!” the wife shouted. But then they noticed the salt went everywhere. “Make it stop,” the wife said. But the husband didn’t know how. “Mill, please stop grinding! Please, no more!” His words didn’t work. The mill kept grinding. Finally, the young husband threw the mill into the sea as far as he could.
And there it’s been, for hundreds of years, endlessly grinding salt. That’s why the sea is salt.

Message Dear Wang, Great to hear you are coming to the USA! I do hope you can stop by and visit us in the Big Apple — a popular name for New York City. There are so many things to see and do here. It would take a lifetime to list them all: Chinatown, Wall Street, Central Park, to name only a few. But knowing you as I do, I’d suggest walking through Midtown Manhattan. It is very popular in the USA and just can’t be missed! People often say that no visit to New York City is complete without a trip to Broadway! Broadway with its cafés, street performers（表演者）and colorful signs really represents New York’s loud spirit! As Broadway is the heart of the American theater industry, it’s at night when it truly comes alive. Broadway is well-known for its big theaters. They show Shakespeare, modern plays, dance shows or musicals — take your pick! With your love of singing and interest in drama（戏剧）, I’d recommend（推荐）a musical. It’s a great and moving experience that I’m sure you would love — a bit like Peking opera! Many musicals are based on classic stories like Les Miserables or Peter Pan, and they might even inspire（激发）you to read the books, too! My big news is that I am going to China on vacation this winter. I am looking for places of interest in China. Can you recommend some to me? See you soon! Leslie |

Otters（水獭）are cute water animals. These days, keeping otters as pets is getting popular. In Japan, some “otter cafés（咖啡馆）” are open for business. People can pay to play with the otters there and to take photos with them. In Indonesia, people go swimming with their pet otters and take funny videos. These photos and videos posted online have interested more people to buy otters as pets.
However, these enjoyable photos and videos hide the damage（损害）that the online trade is doing to otters. In fact, wild otters are facing many threats—they have long been hunted（猎杀）for their coats; in some places, fishermen have been killing otters in order to stop them from eating fish; and now, the online pet trade has become another big problem for otters.
In the wild, baby otters usually stay with their mothers during their first year of life. According to a report, 70% of the otters sold online are under one year old. These baby otters have been stolen from their mothers. When they are kept as pets by humans, they do not live full and natural lives.
Otters are very social. They live in family groups of up to 15 in the wild. Keeping an otter as a pet can make it very sad and lonely. These animals also need enough space to swim. Their owners’ bathtubs（浴缸）or pools are nowhere near as large as the bodies of water in the wild.
On the other hand, otters simply don’t make good pets. They have a very special fishy smell. If they are kept indoors, they will leave a lot of waste around the house. This would make the smell even more unpleasant. Besides, when otters are unhappy, they will make loud noises and even attack（攻击）people. If a person is hurt by an otter, he or she needs to go to hospital at once.
So, we should stop the otter pet trade and never share photos and videos about them online.
