[Q]: Article: April Fool's Day , was a day of laughing and jokes. This day is kept in many countries, not only in Britain and the USA. This is a day to play jokes and make people laugh. Nobody knows when was the beginning of this custom. Some people connect it with the end of winter and the return of spring which make people merry and ready to play jokes. In Scotland young people were sent for hen's teeth or bird's milk and everybody laughed when they could find such things. In the USA and Britain some people could place a sign on a person's back with the words "push me!" Children often tell a grown-up that his sock is torn or he has something black on his face, and then shout "April Fool!" There is also the old purse trick. A purse is left lying in the street, but when someone wants to take it, it is quickly pulled back by a string which the hidden joker holds in his hand. Or the purse may be filled with stones. Sometimes invitations are sent to people, asking them to come and visit somebody, but when they come they see that nobody expects them. Some people like to telephone to the zoo on the day and ask for Mr. Fish, Miss Fox or Mrs. Cat. All these jokes are very old but still they make people laugh.

[Q]: Article: President Barack Obama has complained about the loss of privacy that comes with being leader of the United States, regretting the loss of simple pleasures such as a long walk or a trip to the car wash or supermarket. "I just miss - I miss being unknown," he said. "I miss Saturday morning, rolling out of bed, not shaving, getting into my car with my girls, driving to the supermarket, squeezing the fruit, getting my car washed, taking walks. I can't take a walk." His dream, he said, was to "go through Central Park and watch folks passing by ... spend the day watching people - I miss that".

[Q]: Article: Are the British people Europeans?This may seem a strange question to Africans and Asians,who tend to think of all white men as Europeans. But the British,when they are in Britain,do not regard themselves as Europeans. The Europeans,to them,are those rather excitable foreigners from the other side of English Channel,who have never learnt how to speak English. Europe is "the Continent":a place full of interests for English tourists,but also the source of almost all the wars in which Britain has ever been involved. Thus,although geographically speaking Britain is a part of Europe,yet the fact that it is a separate island has made its people feel very,very insular . They feel,in many ways,different from the rest of Europe,and they sometimes annoy continental nations by failing to support them,or even to understand them,in time of need. Where did the British people come from?This is quite interesting question,since they are a mixture of many different races ,and all these races invaded Britain at various times from Europe. Nobody knows very much about prefix = st1 /Britainbefore the Romans came during the first century B. C.,but there had been at least three invasions before that. The first of these was by a dark--haired Mediterranean race called Iberians. The other two were by Celtic tribes :first the Gaels,whose descendants are the modern Scots and Irish,some of whom still speak the Gaelic language;secondly the Britons,who gave their name to the whole island of Britain. These were the people whom the Romans conquered. The Romans gave the Britons a good deal of civilization,but they never settled in Britain in very large numbers,so the British race survived until the overthrow of the Roman Empire by the"barbarians"--the numerous Germanic tribes which overran the whole of Western Europe.
