Would it surprise you to learn that, like animals, trees communicate with each other and pass on their wealth to the next generation?

    UBC Professor Simard explains how trees are much more complex than most of us ever imagined.

    Although Charles Darwin thought that trees are competing for survival of the fittest, Simard shows just how wrong he was. In fact, the opposite is true: trees survive through their co-operation and support, passing around necessary nutrition “depending on who needs it”.

    Nitrogen (氮) and carbon are shared through miles of underground fungi (真菌) networks, making sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy. This hidden system works in a very similar way to the networks of neurons (神经元) in our brains, and when one tree is destroyed, it affects all.

    Simard talks about “mother trees”, usually the largest and oldest plants on which all other trees depend. She explains how dying trees pass on the wealth to the next generation, transporting important minerals to young trees so they may continue to grow. When humans cut down “mother trees” with no awareness of these highly complex “tree societies” or the networks on which they feed, we are reducing the chances of survival for the entire forest.

     “We didn't take any notice of it,” Simard says sadly. “Dying trees move nutrition into the young trees before dying, but we never give them chance.” If we could put across the message to the forestry industry, we could make a huge difference towards our environmental protection efforts for the future.

    With five breakout(破纪录的) games, Jeremy Lin has become the NBA's newest star.

    In the New York Knicks' 92-85 won over the Los Angles Lakers last Saturday, Lin had a career-high 38 points. A day later, he led the Knicks to their fifth victory, 100-98 to Minnesota Timberwolves. In his previous games, Lin, 23, had 23 points against the Washington, 25 points against New Jersey and 28 against Utah in his first start.

    Lin is smart. Before graduating from high school in California, he had sent his application to all the Ivy League Schools(常青藤联盟). He only got into Harvard and Brown, and he chose Harvard. In 2010, Lin graduated with a degree in economics.

    Lin is the first Chinese-American player in the NBA. He was born in the US and his family is Asian. Although not born in China, Lin has attracted nearly all Yao Ming's old fans, who see him as a powerful role model.

    He started off on the Golden State Warriors. Lin first signed with the Warriors in July, 2010, but seldom played in games before the start of the fourth quarter. His first time on the court for the Warriors earned him seven points, three rebounds(篮板球) and two assists in just 11 minutes.

    He is really perfect for the Knicks. The New York Knicks has been in need of a reliable point guard and to Mike D'Antoni, the Knicks coach who's going through a difficult season, Lin is a most unexpected figure. Lin just does everything easy and the rest of the guys around him are playing the way we want to," D'Antoni said. "I think it's for real, and it can only get better."

    In 1996 John Jones made an unusual discovery. He had just enlarged (扩大) a piece of paper money for a friend—a Confederate bank note, money issued (发行) by banks in Southern States of America during the Civil War. When he was face to face with the picture, he couldn't believe his eyes: slaves (奴隶) happily picking cotton in their master's fields.

    Jones grew up in South Carolina. He had heard painful stories of slavery from his greatgrandmother. The picture on the money did not match (匹配) the history of African American slaves that he'd heard all his life. “I had never seen that type of picture on money before,” he said.

    Jones wondered why slaves looked so happy. He started doing research.

    Searching for and finding the answers to his questions changed his life. During two years' search, Jones found more than 120 different bills. He discovered that the bills had several things in common. They showed slaves working in jobs related to farming. Many of them showed healthy and smiling slaves at work. None of the bills showed the hardships of slavery.

    Jones wanted to share what he had learned. “I wanted other people to see what I had seen,” he said. He decided to make large paintings of the pictures on the money. After three years of work, Jones had painted more than 80 slavery scenes (场景).He paired each painting with the money on which the picture appeared. “The Color of Money”—an exhibit (展览) of his work—has toured the country.

    Jones' paintings tell an important story about the South 150 years ago. He likes to repeat the saying. “The story is on the money.” In this case, the saying happens to be true.

    It is 6:00a.m.on the first day of the school year. In Chery brook Technology High School, mathematics teacher Eddie Woo is already at work.

    One of the first things before the first bell rings is to set up his tripod（三脚架）and iPad in the middle of the classroom. “I'm Mr. Woo. I record my lessons. I record all of them. In fact, I'm about to record this one,” he explains to his new maths class.

    He started posting videos online in 2012 for a student who was sick with cancer and missing a lot of school, so he started sharing them across the country and beyond. Wootube now has more than 38,000 subscribes(用户) and has attracted almost 4 million views worldwide.

    Cherybrook Technology High School principal(校长) Gary Johnson said Mr. Woo was helping maths teachers in Australia and making maths popular again. “He has an ability to simplify(简化) maths to a level where kids can really understand it.” Mr. Johnson said.

    12-year-old student Emily Shakespear said Mr. Woo's teaching style made maths easy and interesting. “I don't want to say it, but he sucked me into maths,” she said. Owen Potter, who attends high school in Cobar agreed. “It's difficult to understand how someone in Sydney can influence thousands of people across the whole country,” he said.

    Mr. Woo won the 2017 University of Sydney Young Alumni Award for Outstanding Achievement, and he was one of 12 Australian teachers honored at the Commonwealth Bank Teaching Awards.

    If you read and listen to one article every day, your reading and listening skills can improve fast. You can learn quickly and after some time you will not have to translate it into your own language. You will simply understand. Why should you do this?

    When you listen to your native language, you do not translate. You simply understand. The same has to be in English. When you learn English, you have to learn the whole sentences in the context (语境).

    Students, who translate English texts, do exercises and do tests, are very good at translating, doing exercises and doing tests, but they have problems with understanding English in real life. In real life, nobody waits for your translation. People usually use simple English when they speak but they speak it fast. You have to understand with no translation into your native language. If you translate, you cannot be part of communication because you are thinking about the language too much.

    You also have to hear every new word 5 to 10 times if you want to remember it. That's why we use the same words at one level. If you read and hear the same words again and again, you will understand them and remember them. If you know words from one level perfectly well, you can go to a higher level and learn new words. It is important to go step by step, and read and listen to words which are used in English often.

    We are trying to do everything possible to help you learn English fast and understand it. That's why we prepare easy English news for you. If you can use this website every day, you can learn 5,000 words which you need for communication with anybody. Now click the OK button to start.

Big Stuff

Do you know what is the tallest building in the world and where the tallest Ferris wheel is? Have you heard of the world's steepest roller coaster? Have you seen the biggest monster truck? Here are some of the most huge things on Earth.

A Towering Achievement

Burj Khalifa, a tower in Dubai, United Arab Emirates, is the world's tallest structure. The 162-story building, which opened in 2010, stands over 2,717 feet tall. Seen from above, the tower has a Y-shaped design. Its three tall, narrow wings are joined in the middle. Like the legs of a tripod （三脚架）, each wing is supported by the other two.

A Wheel Winner

About 15 miles from the world's tallest building stands the world's tallest Ferris wheel, Ain Dubai. Also called an observation wheel, Ain Dubai stands 820 feet tall. Each of the 48 cabins can carry 40 people for spectacular views of Dubai, United Arab Emirates. Before construction, support columns had to be driven 115 feet down through the earth to reach bedrock.

Extreme Ups and Downs

The world's tallest roller coaster is Kingda Ka at Six Flags Great Adventure. At 456 feet, the peak of the ride towers over nearby Jackson, New Jersey. A 500-foot-tall crane was needed to place the final section at the top. Like many weight-bearing structures, the tower makes use of the most stable geometric （几何的） shape, the triangle.

A Monster of a Truck

Designed and built by business owner Bob Chandler, Bigfoot 5 has held the record for the world's biggest monster truck since 

1986. Other trucks, including Bigfoot models, have been designed to perform better in competitions. But Bigfoot 5 still stands above the crowd, thanks to its 10-foot-tall tires. The tires were originally designed for equipment that drives on Alaska's snowy tundra.
