One of the greatest contributions to the first Oxford English Dictionary was also one of its most unusual. In 1879, Oxford University in England asked Prof. James Murray to serve as editor for what was to be the most ambitious dictionary in the history of the English language. It would include every English word possible and would give not only the definition but also the history of the word and quotations (引文)showing how it was used.

    This was a huge task. So Murrary had to find volunteers from Britain, the United States, and the British colonies to search every newspaper, magazine, and book ever written in English. Hundreds of volunteers responded, including William Chester Minor. Dr. Minor was an American Surgeon who had served in the Civil War and was now living in England. He gave his address as “Broadmoor, Crowthorne, Berkshire,” 50 miles from Oxford.

    Minor joined the army of volunteers sending words and quotations to Murray. Over the next years, he became one of the staff's most valued contributors.

    But he was also a mystery. In spite of many invitations, he would always decline to visit Oxford. So in 1897， Murray finally decided to travel to Crowthorne himself. When he arrived, he found Minor locked in a book-lined cell at the Broadmoor Asylum for the Criminally insane.

    Murray and Minor became friends, sharing their love of words. Minor continued contributing to the dictionary, sending in more than 10,000 submissions in 20 years. Murray continued to visit Minor regularly, sometimes taking walks with him around the asylum grounds.

    In 1910, Minor left Broadmoor for an asylum in his native America. Murray was at the port to wave goodbye to his remarkable friend.

    Minor died in 1920, seven years before the first edition of the Oxford English Dictionary was completed. The 12 volumes defined 414,825 words, and thousands of them were contributions from a very scholarly and devoted asylum patient.

    Many people trying to sell homes find that an increase in home prices has turned the market in their favor. But sellers can still get the short end of the deal if they aren't careful. Here are a few tips for you:

    Don't test your luck. Of course you think anyone who moves into your lovely home should be willing to pay top dollars, especially if you've recently invested in some improvements. But listing a home at a price that's too high above the market price could turn away some buyers.

    Buyers noticing that the home which still hasn't been sold may begin to assume there's something wrong with the house and use that as a reasonable excuse for offering a lower price. And if a home hasn't received any offers after two weeks, it might be time to reset the price.

    A price that's too low can bring about an undesired outcome. Listing your home at or slightly below the market price can have the effect of drawing in a large group of buyers and increase the chances that a home will receive multiple offers. But setting the price too low comes with several risks. One possibility is that buyers will get skeptical of the home that is listed for $15,000 to $20,000 less than similar homes in the area, especially if it's not properly marketed. Once again, people might assume there is something wrong with the home and may not bother to look at it.

    Spy on the competition. Going to other people's open houses can give you a better sense of how your home compares with others on the market. Check out the decoration in their kitchens, the size of their backyards and use the information to figure out where your home should fit in the range of the price. But don't set your pricing just on what you see elsewhere.

    They are called "sea parrots", and sometimes "clowns (小丑) of the sea"!

    Atlantic puffins (海鹦) are small seabirds which are around 25 cm in length. They have black and white feathers and a large parrot-like beak (鸟喙). The beak changes color during the year. In winter, the beak has a dull gray color, but it turns orange in spring!

    Puffins spend most of their lives out at sea, resting on the waves when not swimming. They live on the eastern coast of Canada and the United States, and the western coast of Europe.

    Puffins live off small fish such as herring, hake and sand eels. Puffins flap (拍) their wings up to 400 times a minute and speeding through the air at up to 88 km an hour. Wow! What's more, puffins can dive down 60m under water in search of their favorite fish.

    In spring and summer, thousands of puffins stay together on the coasts and islands of the North Atlantic Ocean to start a puffin family. They usually pair up with the same partner as before some may have been together for 20 years! Puffins dig out a hole usually in a grassy bank. Both parents take it in turn to incubate (孵化) the egg for the next 36-45 days!

Although puffins are not classed as an endangered animal, their population in some places is becoming smaller. The main reasons are overfishing, which can lead to a shortage of food for puffins, and pollution—especially oil spills (溢出). Not only does the oil make these beautiful birds sick, it harms their feathers.

    When you visit America, you will see the word Motel on signs and notice boards. It is made up of "motor" and "hotel" and it is really a hotel for people who arrive by car (however, you don't need a car to stay at one). You have to pay when you arrive for your room, which usually has a bath. Meals are not provided, but there will certainly be a cafeteria (自助餐馆). Americans eat a lot of salads and sandwiches. Along the main roads there are a lot of motels. Each tries to offer more than next. Some provide television in every bedroom; others have swimming pools; and so on. Motels are especially useful when you are in the country, far from a town or city. You will also find them in the big National Parks.

    In these great National Parks, you may meet guests you don't expect to see. An American friend told me a little story. In the middle of a moonless night she heard strange noises outside her motel window in the Yellowstone National Park in Wyoming. Thinking it might be a thief, she jumped out of bed, opened the door and crept towards a dark shadow. As she got close, she saw the thief. She was dreadfully frightened: it wasn't a human thief ­ it was a big black bear. The bear was turning over some empty tins with its paw, looking for tasty bits of food. My friend decided to leave that particular thief alone!

    There are also, of course, places called "rooming houses", where they receive lodgers (房客). You will see such signs as Tourists or Rooms Rent, and you could try one of these. A word of warning ­ looking for a room in New York during the tourist season is like looking for gold on the moon!

Iman, the last Sumatran rhino(犀牛) in Malaysia, died in 2019 — bringing the endangered species one step closer to extinction. Now, Malaysian scientists are hoping to use tissues and cells from Iman and other dead rhinos to bring the population back.

"Before the three rhinos (the last survivors in Malaysia) died, we got their cells, and the cells are still alive — which is why I'm quite confident," Dr. Lokman said. "If we don't have any cells, or have just tissue that isn't living anymore, we wouldn't be able to do anything. But now we have a living thing that we can use. "

The cells came from the rhinos'hearts, lungs and brains. What is the most important is that the team collected stem cells (干细胞). One possible approach is to develop these stem cells into an egg (卵子) and sperm (精子), to create an embryo (胚胎) that will be placed into a surrogate mother (代孕母亲). She will likely be another rhino, either a Sumatran rhino from another country or another species. The other method is to take the egg of a surrogate animal, remove the nucleus (细胞核), and join it with a Sumatran rhino's body cell. This technique was famously used to clone Dolly the sheep in 1996. Dr. Lokman and his colleagues are trying both ways. The team is still in the early stages; next, they need to find a suitable surrogate female.

Sumatran rhinos are listed as critically endangered by the World Wildlife Fund. There are less than 80 alive in Indonesia and Thailand. The fall in the population was first caused by hunting. Later, the situation was worsened by the loss of habitats and human activity. Unfortunately, there are now only five remaining rhino species worldwide, and all are threatened. Some sub-species have already died out; the western black rhino was declared extinct in 2013. And it is a pity that the last male northern white rhino died in 2019.
