In the ancient Arabic story called Ali Baba and the Forty Thieves, the young hero Ali Baba said "Open Sesame" and a door to hidden treasures was opened to him. The old story had a special meaning for Ma Yun. He drew inspiration from it for Alibaba.com--Chinese largest ecommerce(电子商务) website.

    In 1995, Ma Yun was working for a US trading company when he was introduced to the Internet. "I know nothing about computers and has never touched a keyboard," he said. He searched the word "beer" and nothing came up about Chinese products.

    Ma Yun had an idea. Why not build a large Internet market to connect customers with companies from all over the world? They could do business online in that way. That was how Alibaba began. His company grew quickly. But that didn't mean everything went smoothly. In 2000, many Internet companies failed including Alibaba. But later, he was successful because he managed to attract investment(投资) into his company. "You should stick to your dream," he said. "Everyone thought I was daydreaming when I started. But the most important thing is that we believe in our dream from past to today and tomorrow. Of course we made many mistakes, but we never give up."

    Ma Yun is also smart. For him, success in business is like trying to catch a rabbit. "If there are nine rabbits, focus on catching one--don't try to catch them all," he said. "Change your ways if you need to, but don't change the rabbit. Get one first, put it in your pocket and then catch the others. "

    Miss Green was sad. She took her favourite orchid(兰花)to school to show her students. She left the flower in the classroom, but later it was gone. Three students were still in the room. (One of them must be the thief(小偷).

    Two of her students, Max and Nina, decided to help her find who did it.

    The first student they talked to was Maria. "I have a cold," she said." I cannot even speak."

    Patrick was standing next to Maria. "Megan and Maria had already been in the room when I arrived," he said quickly. "I didn't see the orchid."

    Megan, who was known to love pretty flowers best, was the next to answer their questions.

    "Of course it wasn't me," she said to Max and Nina. "I have two orchids at home. I just stopped by to put a book on my desk. Maria was already in the room."

    "So how can you explain that, Maria?" Nina asked.

    "After I practised singing, I stopped to get my notebook, "Maria whispered(小声说). "I'll have a concert tomorrow. I didn't take the orchid."

    Nina and Max had a quick conversation with Miss Green and said, "We think we know who took the orchid."

    On March 14, one of science's brightest stars went dark, Stephen Hawking, the world-famous British scientist, died at 76 in Cambridge, UK.

    Hawking is considered by many to be the greatest scientist in history since Albert Einstein. He came up with the theory that the universe began with the Big bang and will end in black holes. His theories became the base for a lot of later research. He also wrote books to help common people understand the universe. His most famous book is A Brief History of Time, which has sold more than 1o million copies around the world, according to CNN. Besides his scientific achievements, Hawking was also someone who had a strong will. when he was 21, he got a serious illness that stopped him from walking and talking Later in life, he had to sit in a wheelchair and speak using a computerized voice. But this didn't stop him from living a meaningful and colorful life

    He celebrated his 60th birthday by going up in a hot-air balloon; when he was 65, he took part in a zero-gravity (=Ee flight to experience weightlessness. He hoped to travel into space one day. In 2015, Hawking spoke about how he felt life was unfair when he first knew about his illness. But now, 50 years later, I can be quietly satisfied with my life, he said

    It was a Monday morning. When the teacher walked into the classroom, he heard a low voice. "Here's the teacher. I'm sure this boring fellow is going to talk about how to use commas." It was a boy's voice and the teacher knew who he was.

    However, the teacher didn't get angry. He said nothing about it, but really began to talk about how to use commas. And he wrote the following sentence on the blackboard, "Nick says the teacher is a boring fellow." The class laughed and Nick's face turned red. "Now," said the teacher, "I will tell you the importance of commas." He put two commas in the sentence and then said, "Nick, says the teacher, is a boring fellow." The whole class laughed again. Nick felt very surprised first, then his face turned much redder. Finally he couldn't help laughing with the other students, too.

    One day I happened to meet an Englishman in the street and soon we began to talk. As I was talking about how I was studying English, the foreigner seemed to be very surprised, gently shaking his head and saying "You don't say!". I was puzzled, and I thought, "Perhaps this is not a right thing to talk about." So I said to him, "Well, shall we talk about the Great Wall? Have you ever been there?"

    "Certainly! Everyone back home will laugh at me if I leave here without seeing it. The Great Wall is wonderful!" "Yes, it is one of the wonders in the world. And people of many countries have come to visit it." As I went on telling him more about it, he stopped me again, "You don't say!"

    I couldn't help asking, "Why do you ask me not to talk about it?"

    "Well, I didn't ask you to do so," he answered, greatly surprised.

    "Did you say 'You don't say!'?" I asked again.

    Hearing this, the foreigner laughed loudly. He began to explain," 'You don't say!' means 'Really'. Perhaps you know little about English idioms."

    Wow! How foolish I was! Since then I have been careful with English idioms.
