Chinese students' extremely neat handwritten compositions have aroused a heated debate among Internet users since photos of the compositions and a teacher's picky remarks were published on Daily Mail Online.

    “Can you believe this essay is handwritten? ” Daily Mail Online asked.

    The website reported on the compositions that looked like they had been machine printed and on the teacher's remarks at Hengshui High School in North China's Hebei Province, one of China's top 100 high schools. The teacher wrote, “not one stroke (笔画) more, not one stroke less” about some compositions that weren't neatly written.

    The story immediately aroused a heated debate among British Internet users and got 652 comments after it was published on Wednesday. Some British readers were amazed by the neat handwriting and attributed (归于)China's growing development to this strict teaching method. A reader named Jim said, “This is another example of why China is rising to the top”, and his comment gained 72 supports. But some readers thought the too-picky method doesn't make sense in helping students learn better English and suppresses（压制） students' creativity.

    Chinese Internet users also expressed different opinions after English newspapers, a user of China's Twitter like Sina Weibo, posted the story along with its comments on Weibo on Thursday. Since then, the post has received 1, 479 comments. Sina Weibo user wenjinzetui said, “Beautiful handwriting proves an ability”, echoing an old Chinese saying that the style is the man. However, another Weibo user, honorificabilitus, said, “It's meaningless to pursue that neat English handwriting, since learning language is for communicating, let alone English students don't write that neatly. ”

    There are also many Weibo users showing worry about this too-strict teaching method, as weibo user li-owl-stop said, “We should reflect the Chinese-style education, and it's hard to imagine what would happen if all the schools in China adopted the teaching method at Hengshui High School. ”

    If you need to spend time on the road，it's important to find ways to keep safe on your feet．Don't suppose it's your right of way. Yes，you might be crossing at the right place，at the right time，within the crosswalk area，but you are still exposed to danger. It could be a distracted driver，or a cyclist with a loose sense of traffic rules，so you could still get hurt．You can be in the right legally，but that won't be much help when you're in the hospital.

    Follow pedestrian(行人) signals. Just as drivers aren't supposed to speed up to beat a light when crossing through an intersection，pedestrians need to take the same care when obeying their own signals．If the hand is flashing and the countdown is into single digits (数字), stay where you are．Trying to outrun the flashing hand is unsafe，especially as cars try to clear the intersection before the light turns red．

    Give drivers enough time to stop when crossing. Don't suppose that drivers will jam on their brakes when you hit the crosswalk signals. Some provinces，such as Alberta, issue （发出）a ticket if you don't give drivers enough time to brake.

    Cross quickly. Once you've followed all of the other rules，and it is safe to cross the street，don't then just wander along in front of six lanes (车道) of traffic. There's no need to run or jog，but respect the drivers who respected you enough to stop for you.

    For more than fifty years, a worker was forced to sit on the back of a truck and slowly drop plastic barriers（障碍） to set out lanes（车道）on the Golden Gate Bridge in San Francisco. Every day, their direction changes to control the traffic, meaning an employee had to go through the difficult task every twenty-four hours.

    But a new piece of machinery means the work can be completed in a matter of minutes. A new “zipper truck” has been introduced. The vehicle lays and moves a lane barrier as it drives over the bridge. Last weekend, the bridge was closed so the new safety barrier, designed to reduce the dangers of head-on crashes, could be set up.

    For the longest period in its nearly eighty-year history, the bridge was closed early Saturday to all but walkers, cyclists and buses to set up the barriers on the 1.7-mile bridge. A survivor of a 2008 head-on crash on the bridge spoke Sunday from a wheelchair to help introduce the new barrier, made of steel-clad concrete（铜包混凝土）blocks that can move across the bridge's six lanes to meet traffic needs.

    Gr. Grace Dammann pushed for a safer barrier since becoming unable to walk after the accident. She said she decided to drive near the middle of the bridge, which was called the “suicide（自杀）lane”, because she and her daughter were running late. Brian Clark, who was driving in the opposite direction, had just learned his father had cancer. “He suddenly lost control of the wheel, crossed over and hit my car,” Dammann said.

    She said she and Clark became friends as they persuaded（说服）the government to use the MYM30 million barrier. “I am so thankful,” said Dammann, who came to the ceremony with Clark.

    “Clark and I thank you.”

    China and India are leaders in improving global(全球的) tree cover, a new study based on NASA research showed.

    They took a 31.8% part together of the total global new leaf area between 2000 and 2017. China played a major role, adding 25% to this increase, and India added 6.8%, followed by Canada and Russia. The study in the Nature Sustainability journal shows that more than 5.5 million square kilometers of green leaf area was added globally. Since 2000, there has been a five-percent increase in global green cover, it said.

    "The greening over the last twenty years shows an increase in leaf area on plants and trees which is as large as the area of the entire Amazon rainforest," Chi Chen, a Boston University researcher and lead of the study told Nature Sustainability. Large plantation activities to protect forests in China contributed nearly 42% to the country's green cover, and agriculture added another 32%. In India, 82% of the increase in leaf area was because of agriculture.

    "China and India take up one-third of the greening, but hold only nine percent of the planet's land area covered in green plants," Chi Chen told NASA Earth Observatory. "That is a surprising finding, considering the land degradation(退化) in countries with large populations."

    Boston University's research team first detected an increase in global green cover in the 1990s but were unsure about what contributed to the increase. Finally, with the help of NASA's Terra and Aqua satellites research, they managed to find out the increase in leaf cover from different areas and places.

Daphne Soares, a biologist, makes an amazing discovery about alligators. The first time she got really close to an alligator (短吻鳄) was when she was helping to bold down an eight-foot American alligator. It was then that she noticed is face was covered with little black spots. This led to the discovery of the little black dots.

She started her study of the black dots. When she read the books and scientific journals, she learned that people had noticed the dots, but no one really knew what the dots were for.

To find out the secret she placed electrodes (电极) on nerves coming from some of the dots. When the nerves fired, they sent a message to the brain and created a tiny electric current. Just then she heard a small sound over a loudspeaker. She tired to see if the dots acted like eyes and temperature sensors, but nothing worked.

One day she was careless with dropping a tool into an alligator's tank. When she put her hand in the tank to get the tool out, she made small waves in the water. When they reached the alligator's face, she heard a noise over the speaker. She then realized that the dots must be sensitive to the changes in pressure when hit by waves of water.

After that, she is now studying blind cavefish. She is trying to learn whether they are blind from birth or lose their sight as they grow up. She is also doing more research on crocodilians (鳄目). She wants to find out how the genes of alligators with pressure sensors only on their faces differ from the genes of crocodilians that have pressure sensors all over their body.

Lanrick Jr. Bennett holds a unique title in Toronto: bicycle mayor. He led a Halloween Kidical Mass ride recently, which I attended with my daughter, son-in-law, their two dogs, and my granddaughter. He is working towards making cycling mainstream and safe for all residents in the city. I did not know that Toronto had a bicycle mayor; I surely would have voted for him in an election.

The bicycle mayor program is run by BYCS, an Amsterdam-based global NGO that believes "bicycles transform cities and cities transform the world". Standing in the strange but wonderful Bentway, a park built under an elevated expressway, Bennett says, "BYCS has 150 bicycle mayors across the world. And through a few friends putting in some really nice letters of encouragement, BYCS offered me a two-year term as an advocate here in the city of Toronto, becoming the first bicycle mayor of the city."

Bennett says he is boosting the work being done to make cycling more mainstream in Toronto. "I am giving a bit more exposure to the great work that has allowed me to be able to ride a bike throughout the city. It's getting better, we're seeing more infrastructure（基础设施）, and we're seeing more people not wanting to depend on cars as their primary piece. I'm happy that I have been part of a fantastic group thus far," says Bennett.

Since there's still a lot of work to do, Lanrick Jr. Bennett has been working hard to improve cycling conditions in Toronto, and his efforts have been recognized by the community. He has been advocating for more bike lanes（车道）, better lighting, and other safety measures to make cycling a practical option for commuters（通勤者）. It's great to see people like Lanrick

Jr. Bennett working towards making cycling safe and accessible for all residents.
