We recycle(回收利用）rubbish, so why not language? Recycling language means using vocabulary that you have learnt before again and again. However, unlike rubbish that piles up(堆积)in our environment. if we do not recycle language, we simply forget it. So how do you recycle language?
There are basically three ways to do it. The first is through reading. Go back to your favourite articles and read them once more. Just reread them and do not worry about each vocabulary item. If there are some that you are not sure about, make a guess and you will probably guess right. The second way to recycle is through writing. Look at some of your favourite articles and write either a short paragraph or a few sentences in your own words. After you have done this a few times, go back and read through what you have written, checking vocabulary functions. Don’t worry if you have made mistakes. That’s how you learn. The third way to recycle language is by having an imaginary chat with yourself about your favourite articles at home. You can pretend there is someone with you who speaks English and tell him what you are thinking about or how you feel.

Escaping (逃) from a fire is a serious matter. Knowing what to do during a fire can save a life. It is important to know the ways you can use and show them to everyone in the family, for example, you can use stairways, roofs and fire escapes, but no lifts.
From the lower floors of buildings, to escape through windows is possible. Learn the best way of leaving by a window with the least chance of serious injury(伤害).
The second floor window is usually not very high from the ground. An average (平均) person, hanging from the window by the fingertips will have a drop of about six feet to the ground--about the height of an average man. Of course, it is safer to jump a short way than to stay in a burning building.
Windows are also useful while you are waiting for help. Be sure to keep the door closed, before opening the window. Otherwise, smoke and fire may be drawn into the room. Keep your head low next to the window to be sure you get fresh air.
On the second or third floor, the best windows to escape from are those which open onto a roof (屋顶) . From the roof a person can drop to the ground more safely.
【小题1】You can try to escape a fire except _____.

In some science fiction movies, evil robots refuse to die, no matter how hard people fight back.
Now science fiction has become science fact. For the first time, scientists have made a robot that can take a beating(挨打) and keep on going. Scientists from Cornell University made the robot, which looks like a spider with four legs.
Until now, even the most advanced(先进的) robot was almost certain to break down when it was damaged(毁坏). That is because its computer inside simply doesn’t know how to make the machine work after its shape has changed.
To deal with this problem, the scientists put eight motors(发动机) and two sensors(传感器) that read how the machine is working. They all give signals to the machine’s software. Using this information, the computer can then figure out the machine’s shape at any moment.
The new technology is a big advance in robot-making, scientists say, and it’s far from scary. It may someday help scientists create better artificial(假的) arms and legs and give new freedom to people who lose them. It might also help scientists understand how people and animals figure out their own sense of place in space.
“It has been difficult to design robots that can work well when the environment changes or when it’s damaged,” says Olaf Sporns of Indiana University in US. “With this work, we are nearer to solving this problem.”
