2 . Songbirds do have a perfect voice. Every species of bird wakes up at a very particular time in the morning and begins to sing. This is because each species has its own specific waking stimulus (刺激), which is linked to the brightness of the sunlight.
Like human beings have to learn to speak, birds also have to learn how to sing. They do this in several stages. First, they practise voices and sounds, which is comparable to the early stage in human language development. During the second stage, the birds practise their songs for eight to nine months, until memory and practice match up. The singing is strengthened during the final stage.
Although nightingales got their name as a result of their singing at night, not all nightingales sing at night. Generally, both males and females sing during the day. The night song is used mainly for seeking partners. After succeeding in attracting a female, the male nightingale falls silent and doesn't start his song again until the early morning.
Birds are seasonal singers. We only hear numerous kinds of bird concerts between spring and high summer. This is the time when birds are looking for partners, and when the males aim to impress the females with their song and mark out their territory at the same time. However, even after they have found a partner, male birds continue to sing, because this is the time when they are showing their offspring (幼崽) how to sing.
Birds don’t all sing as well as others, not even within a species. The song of a bird in London will be quite different from that of a bird in Paris or Berlin. Although the members of each bird species share a vocabulary of sounds, dialect differences are quite common. The individual dialects are not natural but are learnt while the birds are children that adopt the dialect of their parents. The young birds always sing as well or as badly as their teachers, because the adults on whom they model themselves vary in style and talent from region to region.

3 . When Alex Lin was 11 years old, he read an alarming article in the newspaper about e-waste. The article said that people were throwing away their e-waste in places it should never go. This was dangerous, the article said, because e-waste contains poisonous chemicals and metals like lead. These harmful substances (物质) can leak into the environment, getting into crops, animals, water supplies — and people.
Alex showed the article to a few of his classmates. They were worried too. But what could they do about this problem with e-waste? How would they even start? “The first thing we did,” Alex says, “was to learn more about the problem.” Alex and his friends spent several weeks gathering information about the chemicals in e-waste and their effects on humans. They learned how to dispose (处理) of e-waste properly and how it could be recycled. “Then,” he says, “we had to find out what the situation was in our town. So we sent out a survey.”
What they found shocked them: Of the people who answered the survey, only one in eight even knew what e-waste was, let alone how to properly dispose of it. Alex and his friends went into action. They advertised in the local newspaper and distributed notices to students, asking residents to bring their unwanted electronics to the school parking lot. The drive lasted two days, and they collected over 21,000 pounds of e-waste.
The next step was to set up an e-waste drop-off center for the town and to find a responsible company to recycle the waste. That was when Alex and his friends learned another scary fact about e-waste — some irresponsible recycling companies don’t break down the e-waste and dispose of it safely themselves. Instead, they ship it overseas to countries such as China and Nigeria, where local environmental laws are not applied. “We checked carefully online to make sure the company we chose didn’t do this,” Alex says.
Because of the work of people like Alex and his team, more and more people are getting the message about safe disposal of e-waste. As Alex says, “Today’s technology should not become tomorrow’s poisonous trash.”

4 . Atomic shapes are so simple that they can’t be broken down any further. Mathematicians are trying to turn to artificial intelligence (AI) for help to build a periodic table of these shapes, hoping it will assist in finding yet-unknown atomic shapes.
Tom Coates at Imperial College London and his colleagues are working to classify atomic shapes known as Fano varieties, which are so simple that they can’t be broken down into smaller components. Just as chemists arranged element s in the periodic table by their atomic weight and group to reveal new insights, the researchers hope that organizing these atomic shapes by their various properties will help in understanding them.
The team has given each atomic shape a sequence of numbers based on its features such as the number of holes it has or the extent to which it bends around itself. This acts as a bar code (条形码) to identify it. Coates and his colleagues have now created an AI that can predict certain properties of these shapes from their bar code numbers alone, with an accuracy of 98 percent.
The team member Alexander Kasprzyk at the University of Nottingham, UK, says that the AI has let the team organize atomic shapes in a way that begins to follow the periodic table, so that when you read from left to right, or up and down, there seem to be general patterns in the geometry (几何) of the shapes.
Graham Nib lo at the University of Southampton, UK, stresses that humans will still need to understand the results provided by AI and create proofs of these ideas. “AI has definitely got unbelievable abilities. But in the same way that telescopes (望远镜) don’t put astronomers out of work, AI doesn’t put mathematicians out of work,” he says. “It just gives us new backing that allows us to explore parts of the mathematical landscape that are out of reach.”
The team hopes to improve the model to the point where missing spaces in its periodic table could point to the existence of unknown shapes.

Although it’s been almost two years now, I can still remember that day as if it were yesterday. We were all glued in front of the television, when Dad came rushing into the house after work to tell us that he had just bought a new boat. He promised us that the following week he’d take us all on a fishing trip. We were all very excited and happy at the prospect of it.
The much-awaited day finally came. After we packed everything onto the boat, Dad started the engine and steered it slowly out of the harbour. We headed out until we were a good distance from the shore. Then, when we found what seemed like a good spot for fishing, Dad stopped the engine.
The sky was crystal clear and the sea was as calm as a sheet of glass. We spent a good couple of hours bathing in the sun, fishing rods in hands, without a care in the world. It was fantastic just being there, staring out at the beautiful blue sea. We caught a good number of fish.
We must have lost track of time, chatting and laughing, because the next thing I remembered was being put into a darkness which was so thick that one could almost cut it with a knife. Looking around, it was all pitch-black. Then, out of nowhere, a big wave came crushing into the boat, nearly overturning us all overboard. If that wasn’t bad enough, we could hear the rumbling (隆隆声) of thunder in the distance—it was unbelievable how the weather had changed so quickly before our very own eyes. The storm was rolling up on us fast and it wasn’t long before the rain started to come down in showers. The rain was so dense and heavy that we could barely breathe.

10 . Animals being extinct from the Earth is a serious issue. When this happens in order to use their fur or skin for fashion, it is even worse, since it’s not even for a matter of human survival. That’s why a London zoo decided to make a powerful statement at the Siamese crocodile enclosure (鳄鱼围栏).
When visitors come in expecting to see a crocodile, they’re greeted with the handbag instead, making a very effective and powerful point about illegal wildlife trade and the harm it takes on the species involved.
A sign by the enclosure reads, “This bag used to be found swimming in slow-moving rivers and streams across Southeast Asia and Indonesia. Over the last 75 years, more than 80% of Siamese crocodiles have disappeared. Many, like this one, were hunted for their skins as part of the illegal wildlife trade.”.
Native to parts of Southeast Asia, Siamese crocodiles are critically endangered and have become virtually extinct in the wild. Due to hunting as well as habitat loss, they are now absent from nearly 99% of their original range. A huge part of the decline of population is due to humans using their wetland habitat for rice farming, and things only took a turn for the worse when large-scale hunting for their skin for commercial purposes began in the 1950s.
The particular handbag that is on display at the zoo was confiscated at a UK airport, according to Benjamin Tapley, leader of reptiles and amphibians at ZSL London Zoo.
Tapley told The Huffington Post, “We made this exhibit, within ZSL London Zoo’s Reptile House, to draw visitors’ attention to the destructive impact the Illegal Wildlife Trade (IWT) is having on species around the world. At ZSL, we are working globally with governments and local communities to protect wildlife, support law enforcement (执法) that targets illegal trade networks, empower local communities affected by IWT and reduce demand for threatened wildlife.”
