The pilot whale（座头鲸）is one of the largest sea animals in the world. Some of them can be 7 meters long and 3000 kilos heavy. There are about 4000 pilot whales in the world. Most of them live in the Pacific and the Atlantic. A few of them can be seen in Bohai and other big seas in China.
In September, a tragedy happened on the west coast of Tasmania,
Australia. As many as 380 pilot whales became stranded（搁浅）and died. It may be the largest stranding happened in Australia on record, the BBC reported.
For centuries, the whales stranding happened all over the world. Why do pilot whales do this? Scientists did a lot of studies, but they say the reason about that is often unknown. Instead, they offered some different guesses.
Some scientists say the whales catch small fish for food and get stranded because they are not noticing where they are going. Others think that the earth has a geomagnetic field（地磁场）, which makes the whales change their ways of travelling into the wrong place.
There is another guess. Pilot whales travel in large groups. “If one head whale wrongly takes the whole group far away the deep sea, the others will not leave. ” said Shery Gibney, a great scientist from New Zealand. “Some will come in and try to help, they get stranded on the beach, then more will come. ”
Pilot whales can float （漂浮）in the deep water easily although they have a very large body. If they get stranded, their heavy body can slowly kill themselves. More than 90% of all the stranded whales will die, according to the NOAA of the US.

【推荐1】Dolphins (海豚) are very beautiful and very nice animals. There are 17 different kinds of dolphins. Small dolphins, like Maui’s dolphins, are only 1.2 meters long and 40 kilograms. The biggest dolphin, called an Orca, can be 9.5 meters long and 10 tons. It doesn’t matter the size, though. All dolphins can talk. Maybe they cannot talk with words, but they can talk with sounds.
Dolphins like to swim beside each other. They travel in a group. We call a group of fish a “school”. They do not study, but they travel together. Dolphins are mammals (哺乳动物), not fish, but they swim together in a school. Dolphins talk to the other dolphins in the school. They give information and they show their feelings. They tell when they are happy or sad or afraid. They say “Welcome” when a dolphin comes back to the school. They talk when they play.
They make few sounds above water. They come up out of the water because they need to breathe (呼吸) air. They make many more sounds under water. People cannot hear these sounds because the sounds are very, very high. Scientists make tapes of the sounds and study them.

【推荐2】The Mogo Wildlife Park, an Australian zoo, saved all of its animals facing danger from bush fires (林区大火), thanks to a zookeeper, who brought monkeys, pandas, and even a tiger to his home. The Mogo Wildlife Park is located in the South coast. It is just 10 kilometers from Bateman’s Bay, a popular tourist place that has been seriously influenced by the fires, The fires have made thousands of people leave their homes and at least eight people die.
The zoo houses nearly 200 animals, including Sumatran tigers and southern white rhinos. Chad Staples, the director of the zoo, told the Broadcasting Company that zookeepers were well-prepared to protect the animals as bush fires broke out over the New Year’s Eve. “Thanks to the amazing staff here and a plan, no one is hurt, not a single animal,” Sara Ang from the wildlife park told BBC Radio 5 that some of the smaller monkeys and red pandas were moved into Staples’ home. Staples told the ABC that zookeepers felt it was safer to keep larger and more dangerous animals including lions and gorillas in their night enclosures (圈地) where they would feel more comfortable as bush fires burned around them.
Staples told The Times that the team on-site fought against fires at the 65-acre park for several hours. He thanked his staff for working tirelessly to protect the animals because they “love them like their own family”. The zoo confirmed on Tuesday that every animal was “safe and in wonderful care.”

【推荐3】In many places, people build roads through animals’ habitats (栖息地). All day long, cars and trucks pass by. The animals can’t always stay away from the road. They may need to cross it to get their food and water. The road is dangerous. If a car hits an animal, the animal would be badly hurt or even killed. The people in the car would get hurt, too. Animals need a way to get around their habitat without having to walk across the road. But how?
Some people have thought of a solution (方法). They build wildlife corridors (走廊) that let animals cross roads safely. Some wildlife corridors are bridges that go over roads. People plant trees and grass on these bridges so they look like the natural habitat. Other wildlife corridors are tunnels (隧道) that go under the roads. Animals can look through them and see the habitat on the other side.
Different animals like to use different kinds of corridors. Some animals, such as moose and deer, like open spaces. They like bridge corridors better. Other animals, like black bears, like the tunnel corridors.
Wildlife corridors help animals get around their habitats to find food. They also keep people from getting into dangerous accidents. They are a great way for animals and people to live in the same area safely.

【推荐1】It seems that technology (技术) is everywhere. Computers and smart phones are at the center of almost everything we do. They constantly (持续地) require (需要) our attention: We text (发短信) our friends with them during the day, sleep with them by our beds and check our messages as soon as we wake up.
In the future, technology will no longer be troubling us all the time. Instead, we will use calm (平静) technology which was first developed by scientist Mark Weiser in the 1970s. In his opinion, calm technology works quietly but constantly. We know it is there, but we don’t pay much attention to it. According to Mark, the best technology should be invisible (隐形的) and let you live your life.
We already use many different types of calm technology in our everyday lives. Do you have a smoke alarm (警报器) in your house? That smoke alarm is always there, checking the air for smoke and quietly keeping you safe. It only reminds (提醒) you it’s there when you’ve burnt your bread! Or there may be lights in your home or school. When somebody passes in front of their sensors (传感器), the lights turn on. You don’t think about this type of technology until you see the light go on.
In the future, we can imagine our houses will use calm technology to open the curtains for us in the morning, to turn down the heat when we leave, or even to choose the best music for our mood (情绪). The minute we walk through the door, our house will respond (响应) by turning on the lights and music, and perhaps even starting to prepare our dinner!

【推荐2】We’ve all been there. You’re working on a big project that needs to be finished by the end of the day, and somebody interrupts (打断) you to stop your work for a short period of time. For example, they show you photos of their vacation, or they tell you about their weekend. While those interruptions can be annoying, new research from the University of Cincinnati says that they could have some real benefits as well.
Researchers surveyed 111 people twice a day for three weeks, asking them questions about their experiences at the office that day. The survey asked them if they had been interrupted at work, how mentally tired they were, and how satisfied they were with their job.
The study found that while interruptions can have a negative influence on a worker’s productivity (效率), the social aspect of stopping work to talk to a coworker can help them feel more like they belong. That is to say, they feel comfortable or welcome in the situation or place.
The lead study author Harshad Puranik said that this feeling of belonging in the workplace can increase a worker’s job satisfaction, which is a feeling of happiness because one’s wants or needs have been met, even if the work itself is being negatively affected by the interruption.
If you still don’t want to be interrupted at work, there are some things you can do. For example, you can get to the office before anybody else arrives, so you have time to work alone, turn your phone off, or just tell people that you are too busy to talk.

【推荐3】Chinese scientists say they have developed robotic fish that can remove (去除) microplastic particles (微塑料颗粒) from water environments.
Researchers working on the project say the robots could help to clean up plastic pollution in oceans around the world. The robot swimmers are about 1.3 cm long.They are made of a soft chemical material.The robots are built to remove microplastic particles which are smaller than 5 mm while moving through the water. Studies have found that microplastic pollution has been discovered in many natural environments. The material comes from the breakdown (分解) of plastic products and industrial waste.
The project was started by a team at Sichuan University in southwestern China. The researchers say the robots have already worked well in sallow (浅的) waters and they plan to carry out more tests in deeper waters. The team says the robots can be controlled by light. They can swim up to 2.76 body lengths per second. This is faster than most similar soft robots.
Wang Yuyan is a member of the research team. According to her, the small, lightweight robot is now being used to collect microplastics for research purposes. She also says that the team plans to increase that use, so the robot fish can remove plenty of microplastic waste from deep ocean areas.
According to the team, the fish can take in different kinds of microplastics and even repair itself when damaged. And if a robot fish is accidentally eaten by a real fish, it could safely digest (消化) the material.
Wang says similar robots could be developed to be placed inside the human body to remove unwanted materials or diseases.

【推荐2】Students learn their lessons in class. In class, teachers teach them. Students sit in the classroom listening to the teacher. This is a way of learning. Is this the only way for students to learn something? Of course not. There is another way to learn. That is, students can teach themselves. For example, if you cannot remember something when you are doing your homework, you can look through your book to find the answer. This is a way to teach yourself. And it is not a difficult thing. We can do this at any place and at any time.
How do you teach yourself? The first thing you must do is reading. Read something interesting. The second is that you must ask yourself questions. Many clever students often do this. The questions are about something you don’t understand or you want to know more about. You can write down these questions. The third is to answer the questions yourself by thinking hard , by reading the texts（课文）or other books, and sometimes by asking other people. These are ways of teaching yourself. And if you do these things for a long time, you will succeed（成功）in your study.

March 25 this year provides you with a good chance to learn about safety. This day is called the National Day of Education on the Safety of Elementary and Middle School Students (全国中小学生安全教育日), NDESEMSS for short. The theme of the day this year is to give students more knowledge about safety and make sure their lives safe. Unlike car accidents which hurt more grown-ups, the main accidents for elementary and middle school students come from stampedes (踩踏), earthquakes, fires and sports injuries (伤害). What can we do to keep ourselves safe? Different accidents have different self-protection advice. A stampede is possible anywhere. The larger a human crowd gets, the more likely stampedes become. When students around you begin to push, stand still and try to hold onto something, or stay in a corner until the crowd leaves. If you fall down in a moving crowd, cover your head with both hands. Lean to one side, curl up your body and bend your legs. Earthquakes are common natural disasters. When you feel the ground shake, drop down, take cover under a desk and hold on. You should stay indoors until the shaking stops. If you are outdoors, don’t run into buildings, don’t stay near buildings, trees or power lines. When there’s a fire, follow the teachers’ instructions, leave the classroom quickly and use a piece of wet cloth to cover your mouth and nose so that you don’t breathe in smoke.  |
