    Nowadays, the hazy weather frequently appears in our hometown.

    Most nations have at least one type of food that people from other countries think is unusual or unethical（不道德的）to eat. In France, people eat horse meat and frog legs. In South Korea and parts of China, restaurants serve dog meat. And in Australia, it's common to cook kangaroo meat on the barbecue and use emu（鸸鹋）eggs to make pancakes.

    The kangaroo and emu are native to Australia. Both animals are important to the national image of Australia and appear on the Australian coat of arms. They're also central figures in the history of the indigenous（土生土长的）Australian Aboriginals（土著人）. However, Aboriginal tribes still hunt these animals for their meat, fur and fat.

    Today, Australian people continue to eat these animals. One of the reasons people eat kangaroo meat is that it's high in protein and low in fat, so eating kangaroo is a good option for anyone on a diet. It's also cheaper to eat kangaroo meat than other red meats. Because of this, a lot of university students choose to buy kangaroo meat. BBC News also reported that Australian scientists believe that eating kangaroo meat is good for the environment--kangaroos have different digestive systems than cows and sheep, meaning they produce less methane（甲烷），the second biggest contributor to global warming.

    While emu meat is high in iron and vitamin C, most people don't think it tastes good. For this reason, they prefer emu eggs. One egg is large enough to make seven omelettes（煎蛋）. And while it's illegal to collect emu eggs from the wild, they can be bought from emu farms. Rather than cracking the beautiful dark shell, it's better to drain it by putting a small hole at each end and blowing. Afterwards, you can even carve a design into the eggshell.

    I learned to do wood work when I was very young. I remember I made my first project—a small table when I was 9 years old. I was so1of it that I looked upon it as if I had created a(an)2. It was absolutely beautiful and it had taken me six weeks to3it. I could hardly wait to give it to Mother Winters as a(an)4. She was the head mistress of our orphanage（孤儿院）, who was always kind but5with us.

    As the tables were not dry from the clear coating(清漆), our woodworking teacher told us to wait a few days before taking them to our dormitories. But I was just so6and happy that I couldn't wait. I dashed out like a7, carrying my table, smiling from ear to ear.

    When I reached the dormitory I placed the little table beside my bed. I was8it when Mother Winters entered. She walked over to the table. Running her hand9it, she noticed that it was still wet.

    “Were you 10to bring this home?” she asked.

    “No, ma'am,” I 11with my head down.

    She ordered me to throw the table out and so I did. After she left, I immediately opened the door to get it back. There was 12stuck all over. I brushed and cried, but the dirt would not come off.

    I hid the table in my closet and never 13it. However, a year later during a cleaning-up, it was discovered. Painfully, I had to give the table to Mother Henderson, my houseparent, thinking that she would 14it away.

    Thirty years later at a reunion, I15that Mother Henderson was living nearby, so I drove up to see her. We talked cheerfully for a long time. As I was about to leave, she asked me to come down to her 16to get something important. I followed her 17into a dark corner. She picked something up.18she turned around, I could see that she was holding a little table. Mother Henderson kept the little table that I had given up for lost so long ago.

    Jack Ma's net worth increased $2.8bn overnight as Alibaba forecast sales growth that topped every analyst's estimate, despite the fact that China's economy is slowing down.

    Mr. Ma, aged 52 this year, is now the richest person in Asia and 14^th wealthiest in the world, according to the Bloomberg Billionaires Index. His net worth has climbed $8.5bn this year to $（4）8bn.

    The latest surge came after China's largest e-commerce company forecast 45 to 49 percent revenue(收入) growth in the year ending March, demonstrating how investments beyond online shopping are paying off. Shares in Alibaba, where Mr. Ma is chairman, rose 13 percent to a record high.

    Alibaba and Tencent, which dominate online shopping and social media, respectively have ventured(冒险) deeper into new areas from cloud computing services to streaming music and video as the country's economy slows. Alibaba is capturing more digital advertising spending by incorporating(合并) social elements such as video in its shopping sites.

    Alibaba is holding meetings with investors this week. On Friday, the former English teacher said he wasn't going to discuss corporate forecasts. He took the stage instead to describe how his company had become effectively the world's 22^nd largest economy—just after Argentina—in terms of transaction(交易) by never fearing to think big. Mr. Ma, who said Alibaba revises 10-year plans annually, foresaw the company becoming the fifth-largest eventually by 2036 by serving a burgeoning Chinese middle classes, taking advantage of global trade and making use of its valuable data.

    Ma's comments about the evolution of data-driven technology echoed Masayoshi Son, Chairman of Japan's SoftBank. SoftBank—Alibaba's largest shareholder—has invested billions in companies such as ARM with the intention of staking out a leading position in the future Internet of Things.

    “The Internet of Things is going to be big because in the past, machines drink electricity,” Mr. Ma told investors. “In the next 20 years, machines will drink data. In the future, no company, no country, no business can survive without data.”
