The Nile in Egypt, running 6, 650 km, is the longest river in the world. 【小题2】Now it is down to 2 billion m' or so. Australia's Murray River reaches the sea only every other year. One fifth of America's Rio Grande has no water, either.

Everybody hates rats. But in the earthquake places of the world – Japan, Los Angeles, Turkey – rats will soon be man’s new best friends.
What happens after an earthquake? We send in rescue(救援) dogs. Why? Because they can smell people. Dogs save lives. They help rescuers to find living people. But dogs are big and they can’t get into small spaces. So now a new research project is using a smaller animal to save lives: the rat.
How does it work? First, the rat is trained to smell people. When this happens, the rat’s brain gives a signal. This is sent to a small radio on its back, and then the rescuers follow the radio signals. When the rat’s brain activity jumps, the rescuers know that someone is alive. The rat has smelled that person.
Although there are already robots which can do this job, rats are better. Christian Linster at Cornell University, New York, says, “ ‘Robot’ noses don’t work well when there are other smells around. Rats are good at that.” Rats can also see in the dark. They are cheaper and quicker to train than dogs, and unlike robots, they don’t need electricity.
The “ rat project” is not finished, but Julie Ryan of International Rescue Corps in Scotland says, “ It would be fantastic. A rat would get into spaces we couldn’t get to and a rat would get out if it wasn’t safe.” Perhaps for the first time in history, people will be happy to see a rat in a building ( but only after an earthquake, of course.)
