There are more bicycles than residents in the Netherlands,and in cities

like Amsterdam and The Hague up to 70% of all journeys are made by bike.

    The BBC's reporter,Anna Holligan,examines what made everyone get back in the saddle（车座）.

    Before World WarⅡ,journeys in the Netherlands were mainly made by bike, but in the 1950s and 1960s,as car ownership increased quickly,this changed.As in many countries in Europe, roads became increasingly crowded.

    The jump in car number caused a huge rise in the number of deaths on the roads.In 1971 more than 3,000 people were killed by motor vehicles,and 450 of them were children.In response a social movement demanding safer cycling conditions for children was formed.Called Stop de Kindermoord,it took its name from the headline of an article written by journalist Vic Langenhoff whose own child had been killed in a road accident.

    The Dutch love of the motor vehicle was also shaken by the Middle East oil crisis of 1973,when oil-producing countries topped export to the US and Western Europe.

    These twin pressures helped to persuade the Dutch government to invest in improving cycling infrastructure（基础设施）and the Dutch urban planners started to change from the road-building policies designed mainly for cars.

    To make cycling safer and more inviting,the Dutch have built a vast network of cycle paths.These are clearly marked,have smooth surfaces,separate signs and lights for those on two wheels,and are wide enough to allow cycling side by side and overtaking.

    Even before they can walk,Dutch children live in a world of cycling.As babies they travel in special seats on bikes.As the children grow up they ride their own bikes.And,as the Dutch are not allowed to drive until 18,cycling offers teenagers an alternative form of freedom.

    The state also plays a part in teaching,with cycling lessons a compulsory（必修的）part in Dutch schools.All schools have places to park bikes and at some schools 90% of pupils cycle to class.

    Some people learn a second language easily. Others have trouble learning a new language. How can you help yourself learn a new language, such as English? There are several ways to make learning English a little easier and more interesting.

    The first step is to feel positive about learning English. If you believe that you can learn, you will learn. Be patient. You do not have to understand everything all at once. It is natural to make mistakes when you learn something new. We can learn from our mistakes. In other words, do not worry about taking risks.

    The second step is to practice your English. For example, write a diary every day. You will get used to writing it in English, and you will feel comfortable expressing your ideas in English. Several weeks later, you will see that your writing is improving. In addition, you must speak English every day. You can practice with your classmates outside class. You will all make mistakes, but gradually you will become comfortable communicating in English.

    The third step is to keep a record of your language learning. You can write this in your journal. After each class, think about what you did. Did you answer a question correctly? Did you understand something the teacher explained? Perhaps the lesson was difficult, but you tried to understand it.

    You must be positive about learning English and believe that you can do it. It is important to practice every day and make a record of your achievements. You will enjoy learning English, and you will feel more confident in yourself.

    You can't imagine how terrible I felt at that time. A month before my first marathon, one of my ankles was injured and this meant not running for two weeks, leaving me only two weeks to train. Yet, I was determined to go ahead.

    I remember back to my 7th year in school. In my first P.E. class, the teacher required us to run laps and then hit a softball. I didn't do either well. He later informed me that I was "not athletic".

    The idea that I was "not athletic" stuck with me for years. When I started running in my 30s, I realized running was a battle against myself, not about competition or whether or not I was athletic. It was all about the battle against my own body and mind. A test of wills!

    The night before my marathon, I dreamt that I couldn't even find the finish line. I woke up sweating and nervous, but ready to prove something to myself.

    Shortly after crossing the start line, my shoe laces(鞋带) became untied. So I stopped to readjust. Not the start I wanted!

    At mile 3, I passed a sign: "GO FOR IT, RUNNERS!"

    By mile17, I became out of breath and the once injured ankle hurt badly. Despite the pain, I stayed the course walking a bit and then running again.

    By mile 21, I was starving!

    As I approached mile 23, I could see my wife waving a sign. She is my biggest fan. She never minded the alarm clock sounding at 4 a.m. or questioned my expenses on running.

    I was one of the final runners to finish. But I finished! And I got a medal. In fact, I got the same medal as the one that the guy who came in first place had.

    Determined to be myself, move forward, free of shame and worldly labels(世俗标签), I can now call myself a "marathon winner".

    Antarctica's ice white environment is going green and facing other unexpected threats. Scientists say that as temperatures go up in the polar area, invading (入侵) plants and insects, including the flies, cause a major threat.

More and more of these invaders, in the form of larvae(幼虫) or seeds, are surviving in coastal areas around the South Pole, where the temperature has risen by more than 3℃ over the past three decades. Glaciers have melted, exposing more land which has been occupied by mosses that have been found to be growing more quickly and thickly than ever before—providing potential green homes for invaders.

    “The common house flies are a perfect example of the problem the Antarctic now faces from invading species,” said Dominic Hodgson of the British Antarctic Survey. “It comes in on ships, where it exists in kitchens and then at bases on the continent. It now has an increasing chance of surviving in the Antarctic as it warms up, and that is a worry. Insects like the house flies carry bacteria that could have a deadly effect on native lifeforms.”

    The Antarctic has several native species of insects. Together with its native mosses these are now coming under increased threat from three major sources: visiting scientists increasing numbers of tourists and global warming. However, it is global warming that is the main driver of the greening of Antarctica.

    In 2015, more than 38, 000 tourists visited Antarctica. “These tourists are often very careful about not leaving waste or having mud. But they could carry seeds or larvae on their boots when they set foot on the Antarctic, “ said Hodgson.

    More and more invasive insects and plants have been found on the Antarctic and have required removal. “The insects and plants that are native to Antarctica have survived there for thousands of years,” said Hodgson, “We have got to act now if we want to save the environment.”

    How many times have you come back and felt terribly tired, feeling like your head is going to explode? Sounds familiar, right? Well, there are several ways to reduce the frequency of headaches, and those are: eating balanced diet through the day, making sure your body is well hydrated (保持身体水分);getting some exercise to remove the negative energy, like helping yourself with a short massage (按摩)on your head.

At a snow park in Zhangiakou, Hebei, Chinese teenage snowboarder Su Yiming won a silver in the men's snowboarding competition on February 7, 2022. It was the first time that a Chinese snow boarder had ever competed in this event at any Olympics. 

Su was introduced to snowboarding at the age of 4 by his parents who were both snowboarding fans. Su fell in love with the sport the first time they took him to a ski center. Later he kept on practicing after class. To save up more time for snowboarding, he would get up at 5 a. m. and finish his homework early. Su just saw snowboarding as a hobby in the beginning. However, on July 31, 2015, when he knew that 2022 Winter Olympics would be held in Beijing, his mind tuned to professional (职业性的) competition. He dreamed of joining in the Winter Olympics. And he decided to go professional. 

In 2018. Su became a member of China's national snowboarding team. In 2020 and 2021, he took home gold medals (奖牌) in all national competitions. In January 2021, he became the first Chinese male snowboarder to finish the Cab 1800-one of the most difficult snowboarding skills. 

Behind his success is Su's hard work. He has made full use of every chance to train more. Usually he arrived at the training center earlier than his teammates. In that way, he could practice more. He even broke several snowboards in one week because of heavy training.
