The Internet (become) part of young people's life. report shows that 38% of students often use the Internet. Most of them get (use) information on the Internet and use the Internet to help in (they) studies. But many students don't use it a good way. Some play games too much and some visit websites they shouldn't look at. So bad things may happen if students spend too much time on the Internet.

    is important for students to use the Internet (proper). Now we have a textbook, uses many examples to teach students some good ways to use the Internet. It gives some useful (advise).

    Some students also make friends on the Internet. But if you want to have a face­to­face (meet) with your online friends, let your parents know and meet in a proper place.

    Futurologists (未来学家) predict that life will probably be very different in 2050.

    TV channels will have disappeared. Today, we can use the World Wide Web to read newspaper stories and see pictures on a computer thousands of kilometers away. By 2050, music, films, programs, newspapers and books will come to us by computer.

    Cars will have computers to control the speed and there won't be any accidents. Today, many cars have computers that tell drivers exactly where they are. By 2050, the computer will control the car and drive it to your destination.

    Many factories already use robots. Big companies prefer robots—they don't ask for pay rises or go on strike, and they work 24 hours a day. By 2050, we will see robots everywhere—in factories, schools, offices, hospitals, shops and homes.

    Today, there are devices (设备) that connect directly to the brain to help people hear. By 2050, we will be able to help blind and deaf people to see and hear again with the help of new technology.

    Scientists will have discovered how to control genes. By 2050, scientists will be able to produce clones of people, and decide how they look, how they behave and how clever they are. Scientists will be able to do these things, but should they?

    Owning a smartphone may not be as smart as you think. They may let you surf the Internet, listen to music and snap photos wherever you are…but they also turn you into a workaholic, it seems. A study suggests that, by giving you access to emails at all times. The all-singing, all-dancing mobile phone adds as much as two hours to your working day.

    Researchers found that Britons work an additional 460 hours a year on average as they are able to respond to emails on their mobiles. The study by technology retailer Pixmania, reveals the average UK working day is between nine and ten hours, but a further two hours is spent responding to or sending work emails, or making work calls.

    Almost one in ten admits spending up to three hours outside their normal working day checking work emails. Some workers confess they are on call almost 24 hours a day, with nine out of ten saying they take work emails and calls outside their normal working hours. Nearly two-thirds say they often check work emails just before they go to bed and as soon as they wake up, while over a third have replied to one in the middle of the night.

    Ghadi Hobeika, marketing director of Pixmania, said:" The ability to access literally millions of apps, keep in contact via social networks and take photos and video as well as text and call has made smartphones valuable for many people. However, there are drawbacks. Many companies expect their employees to be on call 24 hours a day, seven days a week, and smartphones mean that people literally cannot get away from work. The more constantly in contact we become. The more is expected of us in a work capacity."

    The passage is about a letter written by Li Qiang who is taking the prize that he won last year. At first he was nervous and (certain) about the journey. However, Wang Ping's guidance, Li Qiang was transported into the future safely.

    Hit by a lack fresh air, his head ached and he tried to make the necessary (adjust) to this new situation. Soon he was back his feet again and flew after Wang Ping in a hovering carriages (drive) by computer.

    Arriving at Wang Ping's house, Li Qiang was shown into a large room with a green wall (make) of trees, leaves provided the room with oxygen. (exhaust), Li Qiang slid into bed and fell fast asleep.
