单选题Every time we open our mouths and speak we label ourselves — I am English, you may be Bulgarian or African. We are all human beings, but sometimes we have communication problems which can lead to suspicion and misunderstanding. If you speak English, you have an advantage. The English language means power and freedom to many. It dominates international relations. It affects nearly all our lives in one way or another, influencing everything from pop music to diplomatic relations. Yet only around 10% of the world's population are native English language speakers. Many of you who are reading now will have struggled to learn the grammar, vocabulary and pronunciation of this very complicated language. But there could be another solution: learning Esperanto. Esperanto, meaning "one who hopes", is an artificial language which is said to be the earliest in the world to learn. It was invented in 1887 by Ludwig Zamnehof, a young Polish optician. The usefulness of Esperanto has been recognized the world over. It is now estimated that around eight million people in over 100 countries have at least some knowledge of it. In Esperanto, we have a language that is easy to learn and fair to all speakers because it belongs not to one nation but to us all. Many people, who have tried to learn other languages and failed, have succeeded in Esperanto because it is so easy. Although it is often seen as a joke and not as an important living language, it has been considered dangerous and governments are sometimes afraid of it. Your view of the world is largely based on the language you speak. If you are French, you have a French view; if you are Chinese, you have a Chinese view, and so on. Peter Miles, a member of the Esperanto Translation Service in England, says that speaking Esperanto gives you a truly international view of the world. He regards himself as a citizen of the world looking down from a satellite circling the earth, who is able to communicate with people all over the world in Esperanto. A nice thought!

单选题Every ten years there is a national census to count the number of people. 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 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 ages 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 need to know people's 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, public 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 computer. 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 properly, 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.

单选题The ocean bottom — a region nearly 2.5 times greater than the total land area of the Earth — is a great frontier that even today is largely unexplored and unknown. Until about a century ago, no one had access to the deep-ocean floor, which was hidden under waters over 3,600 meters deep. To humans, the deep-ocean bottom, totally without light but with intense pressures hundreds of times greater than at the Earth's surface, is an unfriendly environment, in some ways as forbidding and remote as loneliness of outer space. Although researchers have taken samples of deep-ocean rocks and deposits for over a century, the first detailed global investigation of the ocean bottom did not actually start until 1968, with the beginning of the National Science Foundation's Deep Sea Drilling Project (DSDP). Using techniques first developed for the offshore oil and gas industry, the DSDP's drill ship, the Glomar Challenger, was able to maintain a steady position on the ocean's surface and drill in very deep waters, collecting samples of deposits and rocks from the ocean floor. The Glomar Challenger completed 96 voyages in a 15-year research program that ended in November 1983. During this time, the drill ship covered 600,000 kilometers and took almost 20,000 samples of sea-bed rocks and deposits at 624 drilling sites around the world. The samples have allowed scientists to rethink what the planet looked like hundreds of millions of years ago and to calculate what it will probably look like millions of years in the future. The samples have also produced information related to understanding the world's past climates. Deep-ocean deposits provide a climatic record tracing back hundreds of millions of years, because they are largely isolated from the erosion (侵蚀) and the intense chemical and biological activity that rapidly destroy much land-based evidence of past climates. This record provided insights into the patterns and causes of past climatic change — information that may be used to predict future climates.
