问答题An Early History of Australia Before the arrival of European settlers, Aboriginal and Tortes Strait (托雷斯海峡) Islander peoples inhabited most areas of the Australian continent. Each people spoke one or more of hundreds of separate languages, with lifestyles and religious and cultural traditions that differed according to the region in which they lived. Adaptable and creative, with simple but highly efficient technology, Indigenous Australians had complex social systems and highly developed traditions reflecting a deep connection with the land and environment. Asian and Oceanic people had contact with Australia’s Indigenous peoples for thousands of years before the European expansion into the Eastern Hemisphere. Some formed substantial relationships with communities in northern Australia. In 1606, the Spanish explorer Luis Vaez de Torres sailed through the strait that separates Australia and Papua New Guinea (巴布亚新几内亚). Dutch explorers charted the north and west coasts and found Tasmania. The first British explorer, William Dampier, landed on the northwest coast in 1688. But it was not until 1770 that his countryman, Captain James Cook, on the Endeavour, extended a scientific voyage to the South Pacific in order to chart the east coast of the continent that had become known as New Holland, and claimed it for the British Crown. The American war of independence shut off that country as a place to transport convicts, requiring Great Britain to establish a new penal colony. Sir Joseph Banks, the President of the Royal Society, had sailed as a naturalist (博物学家) with Captain Cook, and suggested Australia for this purpose. The First Fleet of 11 ships arrived at Botany Bay in January 1788. Governor Phillip preferred Sydney Harbor and the date he landed in the Harbor,26 January, is now commemorated as Australia Day. The First Fleet carded 1,500 people, half of them convicts. Robert Hughes’ The Fatal Shore (1987) is a classic book on the convict system. Hughes suggests that the penal system had lasting effects on Australian society. About 160,000 convicts were sent to the Australian continent over the next 80 years. The wool industry and the gold rushes of the mid-19th century provided an impetus to free settlement. Scarcity of labor, the vastness of the bush and new wealth based on farming, mining and trade all contributed to the development of uniquely Australian institutions and sensibilities. At the time of European settlement in 1788 it is estimated there were at least 300,000 Aboriginals and Torres Strait Islanders in Australia. European settlement involved the displacement and dispossession of Indigenous peoples. It disrupted traditional land management practices and introduced new plants and animals into fragile Australian ecosystems.

问答题农民工月收入不到1000元 农田面积的不断缩小造成农民工队伍的日趋壮大，同时也带来很多社会问题。我国农民工大多是从农村进城打工的贫困农民，数量已超过1亿。目前，我国城市外来农民工的月工资平均为966元，远高于普通农民的月收入，但与城市居民相比仍处于较低水平。我国农民的平均月收入只有城市居民的四分之一左右。 据国家统计局的一项最新调查显示，我国一半农民工的人均月收入低于800元，19.67%的农民工月收入低于500元。在参加调查的29，425名农民工中，10%的人月收入达到1,500元。调查显示，我国东部地区的农民工最“富”，月平均收入达到1,090元，而中、西部地区农民工的月收入则分别为880元和835元。 我国农民工的月花销平均为463元，其中，住宿72元，饮食235元，休闲47元。为了提高专业技能，有一半的受调查农民工接受过职业培训，24.1%的人是自学“成才”。在5,065名携子女入城的农民工中，只有1.05%的人的子女辍学，而49.2%的农民工除向学校缴纳学费外，还要缴纳“登记费”，平均1,226元。

问答题Dental Health Decay is not the only disease that can cause tooth loss. Another serious disease affects the gums, the tissue that surrounds the teeth. It is also caused by bacteria. If the bacteria are not removed every day, they form a substance that stays on the teeth. The substance is known as plaque. At first, the gums appear to be swollen, and may bleed when the teeth are brushed. This can lead to serious infection of the tissue around the teeth. The infection may damage the bone that supports the teeth and cause tooth loss and other health problems. Studies have found that people with severe gum disease have an increased risk of developing heart disease, diabetes and stroke. Gum disease can be treated by a special dentist called a periodontist. Periodontists are trained to repair the gum areas that have been damaged. This can be painful and costly. Dental health experts say the best thing to do is to stop gum disease before it starts. The way to do this is to clean the teeth every day. People also should use dental floss to remove plaque from between the teeth. Most experts also agree that another way to prevent tooth and gum problems is to eat foods high in calcium and vitamins and low in sugar. Scientists continue to develop better dental treatments and equipment. Improved technology may change the way people receive dental treatment in the future. For example, dentists are now suing laser light to treat diseased gums and teeth. Dentists use computer technology to help them repair damaged teeth. Researchers have developed improved methods to repair bone that supports the teeth. And genetic research is expected to develop tests that will show the presence of disease causing bacteria in the mouth. Such increased knowledge about dental diseases and ways to prevent them has improved the health of many people. Yet problems remain in some areas. In industrial countries, minorities and other groups have a high level of untreated dental disease. In developing countries, many areas do not have even emergency care services. The World Health Organization says people in countries in Africa have the most tooth and gum problems. World Health Organization experts say the dental health situation is different for almost every country in the world. As a result, it has developed oral health programs separately for each area. The WHO oral health program is mainly for people living in poor areas. It provides them with information about mouth diseases and health care. It also studies preventive programs using fluoride in water, salt, mild and toothpaste. And it explores ways to include dental health in national health care systems. Many governments and other organizations provide help, so people can get needed dental health services. But dental health professionals say people should take good care of their teeth and gums. They say people should keep their teeth as clean as possible. They should eat foods high in calcium and fiber. These include milk products, whole grain breads and cereals, vegetables, fruits, beans and nuts. Recent studies have shown that eating nuts can help slow the production of plaque on the teeth. Experts say these activities will help everyone improve their dental health throughout their lives.

问答题进入新世纪以来，中国的经济增长大部分时间保持在10％以上。严峻的国际环境也对中国产生了不利影响，去年第四季度经济增速下降到6．8％，今年一季度为6．1％。虽然增速仍在下滑，但由于一系列扩大内需政策效果逐步显现，下滑幅度缩小，增速趋稳。一季度固定资产投资增长28．8％，高于去年水平，预计投资增长将在财政货币政策作用下继续加快；社会消费品零售总额实际增长l5．9％，同比增速有所提高，但短期内消费需求难以做到大幅增长；进出口总额同比下降了24．9％，在主要经济体尚未复苏的情况下，进出口难有大的起色。此外，影响中国经济的不确定、不稳定因素还较多。未来中国经济增长很大程度上取决于扩大内需，投资的增加将扮演重要角色。扩大投资要注意保民生、保就业和产业结构调整相结合，加快形成实物工作量，拉动即期需求。扩大消费的主要动力在农村和城市中等收入群体，我们的政策措施应继续向这方面倾斜。我相信，中国经济增长将为世界经济复苏和亚洲经济稳定发挥重要作用。

问答题Classes at American College The year at an American college is divided into 2 semesters or 3 quarters. Semesters are 15 weeks; quarters are 10 weeks. American college students usually attend school from September to May. Occasionally their academic pursuits extend into the summer. Students choose their classes a few weeks prior to the start of each term. Universities offer a great many classes in the students’ main area of study and in other areas as well. Students must take both. These include science, mathematics, computer, history and English. Other classes may be just for fun, like dance, theater or sports. Tests usually are given in the middle of the term and at the end3. The final examinations are extremely important. In some classes, the professor asks the students to write a research paper or complete a certain task instead of taking a test. Classes usually are organized through lectures. For example, a student may attend 2 or 3 lectures a week by the professor. As many as several hundred students sit at each lecture. Sometimes they also attend a smaller class to ask questions and discuss what the professor says4. These small classes are taught by professor’s assistants. In science classes, students also have a long laboratory class each week. What do American students study at college? The US Department of Education says the most popular area of study is sciences and management. Next is social science, which encompasses history, sociology, literature, public relations and political science. English is another popular field of study. Then comes computer science and health and life sciences like biology, chemistry and physics. Education is popular, too. Foreign languages are not popular as a main area of study among American college students. However, students at many colleges must study a language other than English before they can graduate. The most popular foreign language is Spanish, followed by French and German.
