[单选题](阅读理解题)Paper was invented by the Chinese in the first century AD. Paper was not made in southern Europe until about the year 1 1 00. Scandinavia--which now makes a great deal of the world’s paper--did not begin to make it until 1 500. Most paper is made from wood. Paper-making is an important British industry and paper from Britain is sold to many countries such as Australia and South Africa. Some of the wood used in the British paper making industry comes from trees grown in Britain, but wood is also bought from other countries such as Norway. One tree is needed for every four hundred copies of a forty-page newspaper. If half the adults in Britain buy one daily paper, this uses up over a thousand trees a day. All over the world, trees are being cut down faster than they are being planted, so there may be a serious need for paper at the beginning of next century.When we think of paper, we think of newspaper, books, letters and writing paper. But there are many other uses. Only half of paper is used for books and newspaper, etc. Paper is very good for keeping you warm. Each year, more and more things are made of paper. Now we hear that chairs, tables, and even beds can be made of paper. But the latest in paper making seems to be paper houses.(1). Where was paper invented?_____ A、 In China. B、 In southern Europe. C、 In Scandinavia D、 In Britain
