On October 12,1989,some British scientists were working at the computers to look for the information they needed.Suddenly they saw a lot of very bright points crossing the computersscreens.At the same time the computers were working much slower.To find out what was happening they stopped their work to check some parts of the computers.To their horror(恐怖),they found out that most of their stored information was got rid of by computer viruses(病毒)!Clearly all these computers had been infected(感染)by computer viruses.
It is said that the computer viruses were made by a group of young men fond of playing tricks.①They all had excellent education.They created the viruses just to show their intelligence(才能).These kinds of computer viruses are named Jerusalem Viruses.These viruses can stay in computers for a long time.When the time comes they will attack(袭击)the computers by lowering the functions(功能),damaging their normal programs or even getting rid of all the information.②
We now come to know that Jerusalem Viruses often attack computers on Friday and that they are spreading(传播)to a lot of computers.Among the countries that were attacked by computer viruses last year are Britain,Australia,Switzerland and the U.S.But till now,how to get rid of the terrible viruses remains a problem.

Mr Jackson lived in the centre of London but he had a hotel near the airport.There a lot of foreigners stayed for night.He didn't know any other language but English and he found it difficult for him to understand the foreign visitors.①Sometimes he had to use the body language to“talk”with them,and tried his best to make himself understood.But he was often misunderstood(误解)and it brought him a lot of trouble.A friend of his who learned a few foreign languages in a university would teach him.He was happy and studied hard.At first he learned some,but soon he found it wasn't easy to remember the words and expressions.His friend advised him to write down the useful expressions in his notebook so that he could use them when necessary.②He did as he was told.He found it helpful for him to do so.
One evening there were plenty of people in the diningroom.They were all busy eating something except a Japanese.He was walking around there and waiting for his wife who was dressing herself up upstairs.Mr Jackson thought to himself,“The man wants to eat something but he doesnt know any English.Let me help him.”

Comera is the only place in the world which has a whistle(口哨)language.①We do not know how and why it began because we do not know the complete history of the island.But we can certainly imagine the reasons for the beginning of the whistle language.There are many deep valleys(峡谷)on the island.A person on one side of a valley can not easily shout to a person on the other side.But he can whistle and be heard.Some of the best whistlers can be heard from four miles away and the record is seven miles.The people who live on the island usually have good teeth,and this helps them to whistle well.They must also have good ears so that they can hear other whistlers.
We can understand why the whistle language continues.It is very useful on the island,and quite easy to learn.When somebody is hurt or ill,the whistle language takes the place of telephone.If the sick person is quite far away from the town,people pass the message from one to another.A boy guarding cattle(放牛)on a hillside whistles to a man fishing from his boat.The last one is able to describe the trouble fully and exactly to the doctor in town.People help one another in the same way when a car breaks or a cow is lost.
The whistle language is hundreds of years old,and probably it will continue to live on for hundreds of years more.Radio and TV often kill the special ways of speaking in the different parts of a country.②But on Comera you are nobody if you cannot whistle.Perhaps soon after TV arrives on the island,the people there will be whistling the news and other facts and opinions.
