A terrifying example of the sea’s power saw 125,000 people die in 12 different countries last week. The destruction was caused when a very big 16 sent tsunamis (海啸) smashing into Indian Ocean coastlines.

Scientists said the quake was as 23 an a million of the atom bombs that were 24 on
Because such waves 26 happen in he Indian Ocean, there is no system in place to 27 coastal communities they are about to be hit.
Tsunami is Japanese for “harbor wave”. They are usually caused by a sudden 28 or fall of he part of the Earth crust (地壳) under the ocean. Tsunamis often happen in oceans and they are most 29 in the Pacific. Normally a tsunami includes a series of waves.
Tsunamis can be very long- as much as 100 kilometers-and be as far as one hour apart. They are able to 30 entire oceans without losing much energy. One of the most striking 31 about tsunamis is that an earthquake on one side of the Pacific Ocean can cause giant waves and destruction on the other side.
When the ocean is deep, tsunamis can travel unnoticed 32 speeds of up to 800 kilometers per hour. They can cross the entire ocean in a day or less. The wave may only be a few meters high in the ocean 33 when it is near the shore and reaches shallow water, the wave builds up very quickly in 34. Witnesses in some areas of

There were two interesting pieces of news items in the paper a few years ago. One was about a man who received a bill from the telephone company for $ 2,000 a month for doing nothing.
The connection between the two news items is simple; computers-the best invention of the 20th century. The telephone bill came from a computer which made a terrifying mistake; that man’s bill was only $ 23.26. The other item was not as amusing. A man walked into the unguarded computer room of a large packaged food company and expertly programmed the computer to pay him $ 2,000 a month for raw meat which he “supplied ” to the company. Of course he never sent the meat, but he certainly received the money . The computer wrote out a bill, and even “signed ” it. It was only a random (随便) check that uncovered the trick. It could be happening in thousands of other companies all over the world.
Computers are not the magical workers that some people say they are. They make mistakes, they’re sometimes slower than human beings and they’re easily fooled.
The US used to conscript (征兵) people with the help of a computer. The army sent out a card, which had to be filled in and sent back. It was easy to avoid being called up simply by spreading candle-wax(腊) on the card. The computer couldn’t read the card, and did nothing with it.
It’s in our everyday life that computers cause many problems. Let’s get back to using people instead of computers, before a mistake that we can’t put right.
