填空题Named after an ex-Governor of New South Wales, Sydney is the State's capital city. Located on the south-east coast of Australia in the temperate zone, it enjoys a mild climate, averaging 14.5 hours of sunshine per day in summer and 10. 25 hours in winter. It is also the largest, oldest, and perhaps most beautifully situated city in Australia. First established by the British as a convict settlement in 1788, it is a modern cosmopolitan city that has developed into one of the nation's major industrial, business, and manufacturing centres. Sydney is home to nearly 4.4 million people (as of 1997). The suburbs reach out from the city centre and harbour some 55 km to the north, 35 km to the west and 30 km to the south, creating a metropolitan area of about 3,000 square kilometres. The 57 square kilometre harbour is one of the largest in the world, and famous for the unmistakable 134 metre high arch of the Harbour Bridge and the graceful sails of the Opera House. It is a busy waterway with ferries, freighters, hydrofoils and pleasure craft. Not far from the city centre are the attractive old residential suburbs of Balmain, Glebe, and Paddington, where many people live in smart terraced houses. Art galleries, pubs, and restaurants abound in the cosy streets that tend to be quite narrow, whereas the suburbs surrounding the city's colleges and universities consist mainly of family homes and multi-unit blocks-an ideal situation for students looking for a homestay, or to rent. Sydney's newer suburbs now have a large muhicuhural population, and local shopping centres reflect the influences of many cultures. As well as scores of cinemas and theatres throughout the city and suburbs, there are numerous clubs which appeal to people of all ages, and cater for all tastes. Pubs are the venue for smaller modern hands, while the big-name popular music artists, both local and international, attract capacity audiences at the huge Entertainment Centre in the heart of the city. In Sydney, a vast array of ethnic and local restaurants can be found to suit all palates and pockets. In summer, car patrons often sit outside at tables under umbrellas, and enjoy the passing parade of shoppers. Students who prefer to cook at home can choose from several large weekend markets, where fresh fruit, fish, and vegetables may be bought more cheaply than at the local supermarket. Sydney also has its own Chinatown. In the heart of the city are several big department stores linked by enclosed over-the-street crossings and underground walkways. Most noticeable are the towering Centrepoint complex and the Queen Victoria Building, both containing many shopping arcades, coffee shops and restaurants. Out of town, in the suburbs, there are huge regional shopping centres. At the weekend markets, bargains can be had when shopping for clothing as well as for a wide range of assorted goods. Australia is recognised as one of the most sports-conscious nations in the world. Sydney boasts an impressive number of facilities for all types of indoor and outdoor sporting activities. Wherever one goes, there are golf courses, cricket pitches, football ovals, tennis and squash courts, and, of course, indoor and outdoor swimming pools. Avid ice-skating and ten-pin bowling fans will find that these activities are also popular and inexpensive. Whatever a student is interested in, it is certain to be available somewhere in Sydney. Outside the colleges and universities the scope for filling the leisure hours is enormous, while on campus the choice is equally varied.

填空题According to a magazine I read recently, we now live in an age of increasing leisure. Not o 1 are more and more people reaching retirement age with their taste for enjoyment and even adventure, but the working week is becoming shorter and the opp 2 for leisure are becoming greater and greater all the time. Not to m 3 the fact that people tend to spend less time travelling to work or may even be working from home. What I can"t understand, h 4 , is who these people are. As far as I can t 5 the whole thing is another one of those journalistic fictions. I admit that there are a lo! of r 6 people nowadays, but I am not sure whether all of them are dashing about learing hang-gliding or sailing singlehanded r 7 the world. My own parents seem to s 8 most of their time gazing at the television. And as for the shorter working week, I wish someone w 9 remind my company about it. I seem to be working longer and longer hours all the time. The little leisure time I have is eaten into by sitting in t 10 jams or waiting for trains to show up at rain-swept platforms. I haven"t noticed any dramatic improvements in my lifestyle either, but perhaps I just have to wait until I get my pension.

填空题 In this section, you will hear a passage which will be read only once. You are required to fill in the blanks with the exact words you have just heard. Remember to write the answers on the answer sheet. Central bank independence has to do with monetary policy's effects in the shot run and the long run. In the short run, an " {{U}}(21) {{/U}} " monetary policy can stimulate the economy to grow faster and to lower the {{U}}(22) {{/U}} rate. In the long run, output and unemployment depend on real factors such as population growth and improvements in technology, and {{U}}(23) {{/U}}. One way to insulate monetary policy from day-to-day political {{U}}(24) {{/U}} is to give the central bank greater independence. In this respect, the Federal Reserve or Fed ranks toward the top among the world's central banks. First, the Governors on the Board are appointed to {{U}}(25) {{/U}} year terms. They are nominated by the U.S. President and confirmed by the {{U}}(26) {{/U}}. Second, the Reserve Bank Presidents are selected by our Reserve Bank's Board of Directors and approved by the Board of Governors. This provides further insulation from {{U}}(27) {{/U}} politics. Third, the Fed covers its own operating expenses, so it isn't dependent on Congressional {{U}}(28) {{/U}}. However, Fed is not free of {{U}}(29) {{/U}} to the government. In fact, the phrase usually used to describe the Fed is "independent within government. " There is a way beyond such {{U}}(30) {{/U}} means to make monetary policy even more independent of political pressure to inflate, because the Congress gives the Fed a clear statement that low inflation is its goal. In fact, a number of other countries recently gave their central banks specific low-inflation goals.
