Good morning, boys and girl. Today I'll talk about going online.

    We know that there are too many net bars around us. The Internet can make our lives interesting and enjoyable. Many of us like going online very much because we can learn how to use the computer. We can learn English and read some newspapers and magazines to know more information around us. It can make us clever in playing computer games. Also we can send e-mails to our friends quickly. It can help us contact(联络，联系) people from all over the world.

    But some students spend too much time in playing computer games and some stay in the net bars all day and all night. Some girls even get to have boyfriends or some boys get to have girlfriends online. They write too many letters to each other. It takes them too much time to chat online so they do worse in their lessons and they don't study well any more.

    I think we mustn't get online when it is time for us to study. We can do it in summer or winter holidays. I think we should get online with our teachers or parents.

    At the same time, if we have lots of free time, we can do some activities after class. We usually have activities from 4：50 to 5：50 in the afternoon . You can play basket ball or football. We also have some interest groups in school, such as drawing, singing and dancing. We can go to the English corner on Monday afternoon. We hope we can spend more time on our subjects or on such activities that we can learn a lot from and less time on the Internet.

    Service on the 102-km high-speed railway between Shenzhen and Guangzhou started on December 26, 2011. A non-stop trip between the Guangzhou South Station and the Shenzhen North Station takes 35 minutes at full speed.

    The train runs at the highest speed of 300 km per hour. All 36 pairs of trains run every day. A one-way first-class ticket costs 100 yuan. A second-class one costs 75 yuan, 5 yuan cheaper than a second-class ticket on the slower line.

    A high-speed train has 556 seats, including 16 seats in the VIP rooms and 50 in the first-class carriage (车厢). It offers more advanced facilities (先进的设施). For example, the seats are more comfortable, there are toilets for the disabled (残疾人), and there are power outlets (电源插座) in the first-class carriage.

    The high-speed service between Guangzhou and Shenzhen will be a convenient choice for many people. “I won't need to travel to the Guangzhou East Station to take a train to Shenzhen,” said Wang Yi, who lives in Panyu district in Guangzhou.

    Many people still prefer the slower trains, because the terminals (终点站) of the high-speed trains are far away from the centres of both cities. “I would not like to take a high-speed train to Shenzhen. I live in the centre of Guangzhou. First I have to get to the Guangzhou South Station. It is a waste of time for me,” said Zhang Lu.

    On March 14, one of science's brightest stars went dark. Stephen Hawking, the world-famous British scientist, died at 76 in Cambridge, UK. 霍金是历史上最伟大的科学家之一。 He came up with the theory that the universe (宇宙) began with the Big Bang (大爆炸) and will end in black holes. His theories became the base for a lot of later research. 他还写书帮助人们了解宇宙。 His most famous book is A Brief History of Time (《时间简史》), which has sold more than 10 million copies around the world. Hawking has great scientific achievements. He is also a man with strong will.

    When Hawking was 21, a serious illness 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. "If one is physically disabled (身体残疾), one cannot afford to be psychologically (心理上) disabled as well," he once said.

    Inventions have the power to change our world. Some inventions are designed for work. Some are just for fun. Others can help people and the planet. Every year, Time magazine shares its best inventions of the year. Below you can read about five of these inventions to learn what's special about each of them.

    An old lady walked into a clothes shop. She asked the salesgirl to show her a new dress in the shop window. The girl stood behind the counter, taking no notice of the request (要求) . The old lady asked again, but she still received no answer. Then the old lady said to herself, "I'm too old to see well. I can't even tell a plastic (塑料的) model from a real girl."

    When the girl heard this, she shouted. "What did you say? Did you say that I am a plastic model?" The lady was greatly surprised. She said to herself, "The model can speak! It must be a robot of a new type."
