The Census Office asks every household to answer questions on a census form. The census counts people by the kind of housing they live in, the

25、 country in which they were born, and the kind of job they do and how they travel to work. Census results are used by a great many people and are available to everyone in many ways. For example, in order to work out present and future needs we must know how people are housed now, and the sizes and a

26、ges of their families. For hospitals, schools and other local services, the size of annual grants made by the Government to these services depends largely on the numbers and needs of people in the area.Many of the figures come from the census. In order to work out future spending for pensions, we ne

27、ed to know peoples ages, how many are men and how many are women, whether they are single or married, and the size of the family. The census shows how many people have moved from one area to another and how the local workforce is changing. This information is used when factories, offices, shops, pub

28、lic transport and places for leisure are being planned. The census is taken in order to provide figures about the nation as a whole. It does not give information about any named person, family or household. Names and addresses are needed to take the census accurately, but they are not fed into the c

29、omputer. After the census, the forms are locked away and will not be released to anyone outside the Census Office for 100 years. The answers you give on your census form will be treated secretly. No one outside the Census Office will see your completed form, but if you refuse to complete your form p

30、roperly, you may be taken to court and the form could be produced as evidence. Everyone working on the census is required to keep it secret and can be prosecuted if he or she improperly reveals information.（分数：10.00）(1).It is necessary to know what sort of housing conditions people have in order to

From morning till night, when Williams was at home

35、, Prince never left his sight, practically ignoring all other members of the family. The dog had a number of clearly defined duties, for which Williams had patiently trained him and, like the good pupil he was, Prince lived for the chance to demonstrate his abilities.When Williams wanted to put on h

36、is boots, he would murmur “Boots“ and within seconds the dog would drop them at his feet. At nine every morning, Prince ran off to the general store in the village, returning shortly not only with Williams daily paper but with a half-ounce packet of Williams favorite tobacco, John Rhineys Mixed. A g

37、un-dog by breed, Prince possessed a large soft mouth specially evolved for the safe carrying of hunted creatures, so the paper and the tobacco came to no harm, never even showing a tooth mark.Williams was a railwayman, an engine driver, and he wore a blue uniform which smelled of oil and oil fuel. H

38、e had to work at odd times - “days“, “late days“ or “nights“. Over the years Prince got to know these periods of work and rest, knew when his master would leave the house and return, and the dog did not waste this knowledge. If Williams overslept, as he often did, Prince barked at the bedroom door u

39、ntil he woke, much to the annoyance of the family. On his return, Williams slippers were brought to him, the paper and tobacco too if previously undelivered.A curious thing happened to Williams during the snow and ice of last winter. One evening he slipped and fell on the icy pavement somewhere betw

40、een the village and his home. He was so badly shaken that he stayed in bed for three days; and not until he got up and dressed again did he discover that he had lost his wallet containing over fifty pounds. The house was turned upside down in the search, but the wallet was not found. However, two da

41、ys later - that was five days after the fall - Prince dropped the wallet into Williams hand. Very muddy, stained and wet through, the little case still contained fifty-three pounds, Williams driving license and a few other papers. Where the dog bad found it no one could tell, but he had found it and

46、s difficult to say exactly how the music we call “rock“ or “rock and roll“ began. Its roots go back to many different countries and many different kinds of music and musicians.Rock music developed mainly from the interaction of black African and white European music. The Europeans and the African sl

47、aves who came to America during the seventeenth century each had their own different kinds of music. Black Africans used heavy drumbeats, a rough singing voice, and the calling of a melody and answer of a chorus. The white Europeans, mostly English and Scots, used a stronger melody, a less heavy bea

48、t, and instruments such as guitars, horns, and fiddles. The history of rock and roll is the history of how rock evolved from these two traditions.From the seventeenth to the twentieth century, musicians in the southern United States developed two new forms of music: the blues, usually played by blacks, and country music, played by whites. Black musicians sang the blues accompanied by a guitar. This music was similar to work songs: stories of troubles and pain, with Ulines/U that were repeated several times. The words “rock and roll“ probably came from the black churches in t
