Nowadays, learning Braille (盲文) is something of a dying art. With thousands of computer programs and other media now available, fewer kids are learning to read Braille and most of them are learning to read by listening. In the United States, less than 10% of the 1.3 million people who are legally blind are Braille readers. However, learning Braille offers students much more than just a way to get information. Listening to information does not teach students how to spell or write well. These skills are better taught by actually reading. This is particularly true when we know that Braille users often are more independent, have a higher level of education and better employment opportunities. Learning to read and write Braille requires lots of practice, which can become dull. This is what the company Lego, which is making Braille Bricks to help blind students learn to read and write, is dealing with. We strongly believe the Bricks can help increase the level of interest in learning Braille.
Instead of the grid (网格) of raised dots normally found on top of Legos, Braille Bricks use the dot groups of the Braille alphabet. This allows the bricks to be “read”, but they still click together like normal Legos. Braille is often written with a special machine called a Brailler. If a student makes the wrong letter using the Brailler, it can’t really be fixed, since the letter is punched (打孔) into paper. Legos, on the other hand, are lots of fun to play with. If a student makes a mistake, fixing it is as easy as moving or changing a brick.
The company is trying the Bricks out with teachers and blind students in schools. Teachers report that students enjoy the Bricks and quickly invent games and fun ways to use them. On Lego’s new Braille Bricks, which are planned to hit commercial stores in the near future, Braille is also translated into numbers and letters allowing parents and educators to follow along.

LEGO Works to Make Bricks from Recycled Plastic
The LEGO Group has been working on a way to make LEGO bricks out of recycled plastic. The bricks aren’t ready yet, but the company says it’s making progress. Making bricks from recycled materials could cut pollution from the company’s bricks by 70%.
Many people are familiar with LEGOs. Developed in Denmark, the plastic building toys have been around since the 1950s. The toys click together firmly, allowing users to build things that don’t fall apart easily. The company calls this ability to hold tightly “clutch power”.
Since roughly 1960, LEGO bricks have been made from a kind of plastic called ABS. ABS plastic makes LEGO bricks very tough, and gives them great clutch power, over and over again.
Sadly, ABS plastic can’t really be recycled, and it takes a very long time to break down. That’s a big problem. The world is struggling with a huge plastic waste problem. And LEGO makes about 110 billion bricks every year.
But since 2015, LEGO has been making an effort to make their products more earth-friendly. Three years ago, the company began making some LEGO parts, like trees, out of a plastic made from sugar cane. Recently, LEGO started using paper bags instead of plastic to reduce packaging.
But making bricks out of recycled plastic is a big challenge. The goal is to make bricks out of PET plastic, which is softer than ABS plastic and can be found in things like bottles and clothing. A recycled one-liter plastic bottle could make about 102×4 LEGO bricks.
Over the past three years, the company has tested over 250 different ways of creating LEGO bricks from recycled plastic. A team of more than 150 people are working on the problem. Tim Brooks, who focuses on environmental responsibility at LEGO, says that experimenting and failing is “an important part of learning”.
Now, the company says they’ve found a way to make a good 2×4 brick from PET. One important step was finding a way of adding things to PET plastic to make it tougher and give it better clutch power like ABS.
“We know kids care about the environment,” said Mr. Brooks. “Even though it will be a while before they will be able to play with bricks made from recycled plastic, we want to let kids know we’re working on it.”
1. What is the benefit of making LEGO bricks from recycled materials for LEGO Company?2. What is “clutch power”?
3. Please decide which part is false in the following statement, then underline it and explain why.
LEGO wants to make bricks out of PET plastic, because PET plastic is earth friendly and it gives LEGO bricks better clutch power than ABS.
4. As a student, how can we contribute to a green environment? (In about 40 words)
【推荐2】The five-hundred-meter Aperture Spherical Telescope(FAST) — the only significant instrument of its kind after the fall of the American Arecibo telescope in Puerto Rico in December, 2020 — officially opened its door for foreign astronomers to use on March 31st this year, hoping to attract the world's top scientific talents. The world's largest radio telescope signals China's ambition as a global center for scientific research.
The FAST in Pingtang, Guizhou Province, travels twice as fast as the US-owned one, and up to three times more sensitive. The FAST is also superior to Arecibo for it can deform and rotate. Work on the FAST began in 2011 and started full operations in January, 2020. The data being collected by FAST should allow for a better understanding of the origins of the universe and aid in searching for alien life.
China has been rapidly strengthening its development of science and technology to rely less on foreign technology. In the past two decades, China has built the largest high-speed train network in the world, finalized its Beidou geolocation system and is now in the process of bringing lunar samples back to Earth.
Denis Simon, an expert on Chinese science policy, said, “China was viewed to be slow in innovation only a few years ago. Improvements in scientific innovation have been rapid recently. With more and more freedom given to the scientific and engineering community to explore new ideas and take bigger risks in the research environment, the risk-off culture in the past has given way to a more enterprise-starting culture.”
1. What can be learned about FAST?| A．It is ready to greet international scientists. | B．It has been running for two decades. |
| C．It is the only telescope to study outer space. | D．It keeps our contact with aliens. |
| A．By example. | B．By explanation. | C．By analysis. | D．By comparison. |
| A．China's dependence on foreign technology. |
| B．Some achievements of China in science and technology. |
| C．The joint efforts of scientists at home and abroad. |

| C．The less limitation on exploration. | D．The strong desire to develop technology. |
【推荐3】Sperm whales (抹香鲸) living in the Eastern Mediterranean numbered not more than 200-300 individuals during the past decade. Alarming results from the Pelagos Cetacean Research Institute, conducting systematic observations since 1998, indicate that the population might have been halved to only 100-150 whales. The main threat to this population is the more than 30,000 ships that annually cross their habitat at high speed and the risk of collision with them.
International and regional agreements force Greece to take action to protect the sperm whales, including their habitat, the Hellenic Trench. The pilot system SAvEWhales, which was developed by a team of Greek researchers, contributes to this direction.
SAvEWhales records the clicking sounds of the sperm whales, processes them and sends the data to a land-based analysis center where computer models are used to detect, precisely locate the animals, and finally forward the localization fixes (定位) to nearby ships, all in real time. Specifically developed software combines localization results with shipping information from Marine Traffic, a leading ship tracking service provider, to assess collision risk. If a ship is on a collision course with a whale, its captain can be warned well in advance, so that the ship slows down and/or changes course in time to prevent the collision.
Despite its promise, it may be some time before SAvEWhales, or something like it, can be in permanent use. So far, Emmanuel Skarsoulis, research director of Greece’s Foundation for Research and Technology-Hellas, and his teammates have already identified a few barriers. These include analytical challenges, such as the difficulty of differentiating individual whales when a group is traveling together. Besides, SAVEWhales can’t pick up the location of singing whales like the Mediterranean fin whale which is also endangered.
Still, passive whale detection is relatively inexpensive and can protect at least one of the endangered whale species in the Hellenic Trench.

【推荐1】It might surprise you to learn that there are conservationists on four legs as well as two. In the 1890s, realizing that imported stoats (白鼬) were having a disastrous impact on local birds such as kiwi, conservationist Richard Henry relied upon his pet dog to help translocate birds to a reserve on Resolution Island. From then on, he kept working and contributed to the world’s first government-backed conservation dogs programme established in 1998.
Dogs have many qualities that recommend them for field work, but it’s their nose that puts them ahead of many humans. Damp surfaces trap odour molecules (气味分子), but dog noses are also remarkably sensitive. Add in a set of other adaptations that allow dogs to filter the air they breathe in to a dedicated smelling area at the back of the nose, you’ve got an extremely excellent detective machine.
Worldwide, dogs have helped scientists to track snow leopards, koalas, gorillas and even killer whales, whose muck (排泄物) only floats on the ocean’s surface for a limited time. For their cooperation, the dogs receive their favourite treat. “We reward our dogs for locating the target by playing balls,” says Hartman, a research scientist. She explains that around 98% of the dogs are from rescue shelters, given up by owners who could not match their energy levels. Enthusiastic dogs are a must for the programme, but trainers need to match this with patience curiosity and hard work.
After the muck sniffers (嗅探器), the next most common task for conservation dogs is live animal detection. Many working dogs were first bred to be pest controllers in agricultural settings. Now conservation dogs are used to find introduced rats and stoats on New Zealand’s island safe havens, feral cats in Australia, mongooses in Japan — even mussels and ants in the US that cause destruction and upset ecosystems. It’s just one of the ways dogs are being employed to keep human activity in check.

【推荐2】The USA，New York—Whales and dolphins are facing increasing threats from climate change，according to a new report published by WWF(World Wildlife Fund)and the Whale and Dolphin Conservation Society(WDCS)．
The report“Whales in hot water？”draws attention to the growing impacts of climate change on whales.They range from changes in sea temperature and the freshening of the seawater because of the melting of ice and increased rainfalls，to a sea level rise，loss of icy polar habitats and the decline of krill populations in key areas. Krill，a tiny shrimp that is dependent on sea ice，is the main source of food for many of the great whales.
The speeding up of climate change adds greatly to trouble from other human activities，such as chemical and noise pollution，which kills some 1，000 whales every day.
“Whales and dolphins have an ability to adapt to their changing environment，”said Mark Simmonds，International Director of Science at WDCS.“But the climate is now changing at such a fast pace that it is unclear to what extent whales and dolphins will be able to adjust.”
Climate change impacts are currently greatest in the Arctic and the Antarctic.According to the report，whales that rely on polar，icy water for their home and food resources are likely to be greatly affected by the reduction of sea ice cover.
WDCS and WWF are urging governments to cut global production of CO2 by at least 50 percent by the middle of this century. The latest report of the Intergovern－mental Panel on Climate Change showed it was possible to stop global warming if the world's emissions start to decline before 2015.

【推荐3】You know the feeling—your ears start to warm up, your tongue goes numb, you start sweating and taking deep breaths. You’ve just eaten something spicy (辛辣的) knowing it would be painful, and, yet, you chose to do it anyway. Are humans just masochistic (受虐狂的), or is there something else going on? The answer lies in both science and history.
Let’s start with the science. Spicy isn’t actually a taste like salty, sweet, sour and bitter—it’s a sensation. This sensation is triggered by a chemical compound (化合物) found in chili peppers called ‘capsaicin’ (辣椒素).When we eat foods containing capsaicin, our bodies are tricked into thinking the temperature is actually rising. In trying to temper the burning sensation, our bodies release endorphins which control pain and, at the same time, give a feeling of pleasure—like painkillers. This is what is happening chemically, but there is also a conscious side to choosing spicy food. Dr Tamara Rosenbaum, Cognitive Neuroscientist at the National Autonomous University of Mexico, explains in an interview that this is because we are rational beings—we know that the burning sensation of chilli does not physically harm us. Furthermore, we derive pleasure from the other ingredients chilli is generally cooked and eaten with, including fat, sugar and salt. So like skydiving, eating chilli is a form of thrill-seeking or ‘benign masochism’, where we get pleasure from a seemingly negative sensation.
This masochistic relationship with capsaicin has been a long one, starting in the Andes of South America, where chilli peppers originate. Humans were one of the few mammals (哺乳动物) on Earth that developed a taste for capsaicin so, archaeological evidence suggests, they started cultivating (种植) chilli peppers about six thousand years ago. Human intervention changed the chilli pepper to suit human tastes and needs—including the pepper’s colour, size and capsaicin content—helping to explain the many different types of chilli peppers now available.
Fast-forward to today, and our love affair with the chilli pepper is going strong. We eat around 57.3 million tons of peppers globally each year, and chilli is a key ingredient in traditional dishes from Mexico to Korea. Maybe we are masochistic after all.

【推荐2】Some of the world’s biggest companies — Apple, Amazon, Facebook — didn’t exist 30 years ago. So what firms are we working for in 2050? That’ s a question put forward by historian Yuval Noah Harari in his new book “21 Lessons for the 21st Century”.
He argues that because technology is changing so fast, it’ s one of the first times in human history when we don’t know what jobs will look like in the coming three decades. “So the best bet is to focus on emotional intelligence (EQ),” he said. “Information is the last thing the kids need. They have too much of it.”
In this book, he focuses on the various challenges facing us today. As he writes in the book’ s introduction: “What are today’s greatest challenges? What should we pay attention to? What should we teach our kids?” One area where these questions crop up is artificial intelligence (AI). Harari believes that AI will completely affect the job market for the next generation of workers.
His first two books — “Sapiens” and “Homo Deus” — became international bestsellers, selling more than 12 million copies worldwide. They were praised by the likes of Mark Zuckerberg, Barack Obama and Bill Gates. Harari’ s books, about the past and future of humanity, attract a great number of fans. Fellow Israeli, actress Natalie Portman, is a fan. So is American R&B star Janelle Monae.
As for Bill Gates, he might be Harari’s biggest fan. So when the New York Times asked him to review Harari’ s latest books, he jumped at the opportunity. “All the three books wrestle with some version of the same question: What will give our lives meaning in the decades and centuries ahead?” Gates wrote in his review. “So far, human history has been driven by a desire to live longer, healthier, happier lives. If science is eventually able to give that dream to most people, and large numbers of people no longer need to work, what reason will we have to get up in the morning?”

【推荐2】Stamp collection was once considered a harmless and educational pastime for small boys. It still is — but with a difference. Grandpa and grandma have joined the small boys, along with shoe clerks, waitresses, truck drivers, college professors , businessmen, presidents and kings. Stamp collecting has today grown into big business.
All the really rare old stamps are already owned by collectors who refuse to part with them. But even if these owners were willing to sell, few people could afford to buy.
A stamp becomes valuable because it is “ rare”. Modern collectors with little money to spend have to create their own “ rarities”. One rarity that stamp collectors look for is an error in the stamp. The error may be so small that it cannot be seen with the naked eye. If it is there, however, it makes the stamp more valuable.
Stamp collectors have another way of making their collections rare or unusual. They bring together as many examples as they they can of a certain kind of stamp. What makes such a collection unusual is the time and the idea that went inot making it. One may collect only stamps of some color. Another may collect only stamps from a certain foreign country, or stamps connected with some person, place or event. Still other collectors are interested in the tiny holes along the edge of a stamp. They may be long or short, round or oval. Some stamps may not have them at all. Another thing that makes a stamp “ rare” is its postmark or its cancellation. Collectors go through a lot of trouble to have letters mailed to them from unusual places.
