the 21st century Most scientists have been saying that human activity not natural factors is the primary cause of the warming Many people both in China and abroad have realized that while we are developing the world we are also destroying the land on which we are living We see garbage sometimes thrown into streams that supply drinking water We find forest fires caused by careless people Beaches and city streets are littered with rubbish 译文 全球变暖是我们在 21 世纪面临的最严重的问题 大多数科学家认为人类活动 而不是 自然因素 是引起全球变暖的主要原因 中国和其他国家的人们也都意识到 在发展世界 的同时我们也在毁坏我们居住的陆地 我们看到有时垃圾被扔进提供饮用水的溪流 森林 因人们的疏忽而起火 海滩 街道上是丢弃的垃圾 1

Light from the sun heats the earth s atmosphere oceans and land making life on the earth possible At the same time a certain amount of heat goes 3 into outer space so that the temperature of the earth is balanced Nowadays less heat can escape because of the increasing levels of carbon dioxide The surface temperature of the earth increased greatly over the last century The warming increases with time and could have many side effects 译文 太阳的射线给地球表面 海洋和陆地提供了热量 使地球上的生命得以延伸 同时 一定数量的热量释放到外太空 这样地球的温度得以保持平衡 现在由于大气中二氧化碳 的含量逐年增加 所以释放的热量也在逐年减少 在过去的一个世纪中 地球表面的温度 大幅度上升 全球变暖日趋严重 同时也带来了许多副作用 1 a certain

as little as possible because these sources would produce a lot of gases Instead we should try to make use of solar energy wind power hydrogen and some new sources of energy Third we can start environmental groups to tell people the importance of protecting the earth 译文 我们应该做些什么来拯救我们的环境 首先 我们可以多种树 树木可以吸收二氧化 碳并产生氧气 其次 我们必须寻找新的能源 人们应该尽可能少地燃烧煤和石油 因为 这些能源会向大气排放大量废气 我们应该尽量使用太阳能 风能 氢以及其他新的能源 最后

their guide Gavin Jones The police said that they had disappeared during an adventure 冒险 tour of Cape York Peninsula This was the second day of the search and the police were now very worried about the safety of the three missing people The police said that the search had covered a wide area but the rainforest was thick and their work was made harder by the recent rain Later on Chief Inspector 警官 Roger Fleet said The travellers had a radio with them If they had been in trouble they would have called us The three travellers left Cooktown very early on Saturday morning in a Toyota car They took a small dirt road that runs down to the Daintree River a dangerous river full of crocodiles 鳄鱼 Chief Inspector Roger Fleet said the tourists wouldn t have got into trouble if they had stayed on the main road A photo of Vicky and Tom was found by a policeman under the Be Careful about crocodiles sign near the river Why was the photo left behind This is just one of the unanswered questions Other questions are Why was the photo 7 left behind Why was the Toyota parked and locked at the edge of the rainforest The police said that the travelers had left a map of the area behind Why Why had someone drawn a cross on the point 地点 where the car is Is this a sign What does it mean If anyone can give information or has seen these three young people contact the local police in Cooktown 35 This

forest a London street a scene from the Wild West and a burning building that never burns down There s only one place and that s Hollywood in California The scenes you see from the tourist train are film sets 布景 in the Universal Studios one of the oldest and largest movie companies 公司 in the USA A visit to Universal Studios brings back memories of great days of Hollywood the films and the stars But they are only memories Hollywood isn t quite the same as it used to be Costs have gone up and confidence has gone down Movie makers are afraid to spend their money on expensive new ideas Instead they repeat old ones The film industry is changing fast Teenagers still go out to the movies The theatre is a good place to meet friends away from home But older people mostly stay home to watch series like Dynasty have become as important to Hollywood as expensive movies These soap opera as they are called show rich powerful families living in beautiful homes and wearing beautiful clothes But the actors and actresses are nearly all middle aged like many of the people who watch them Though it is soap operas that are keeping the film makers of Hollywood in Business big films are still being made in America But more and more of them are made outside Hollywood New York is the most important new center but there are many others as well Movie makers have realized that they don t need Hollywood any more Modern cameras and real houses instead of expensively made copies in a studio Other states especially Florida and Texas are working hard to take the film business away from California They are offering better working conditions and lower cost 8 But Hollywood is fighting back The state of California is trying hard to keep its best known industry 39 From the passage we know Universal Studios is A a very large park B a busy London street C a famous movie company D an old Hollywood movie 40 The movie industry in California isn t as successful as before because A young people don t go to movie theatres any more B there is strong competition from other states C its movie companies are in need of young stars D the state hasn t put a development plan into action 41

expensively made copies of scenes 42 What can we learn about soap operas from the passage A They are teenagers favorites B They are much more expensive C They are less attractive D They are cheaper and easier to make C A new study has found no evidence that sunscreen commonly used to reduce the risk of skin cancer actually increase the risk Researchers from the University of Iowa based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanoma 黑素瘤 They said that they found flaws in studies that had reported associations between sunscreen use and higher risk of melanoma Most health experts believe that by protecting the skin from the harmful effects of the sun sunscreen helps prevent skin cancer which is increasing in incidence 发生率 faster than any other cancer in the United States But questions has been raised about sunscreen and whether it may has opposite effect perhaps by allowing people to remain exposed to the sun longer without burning The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancer people with fair skin 白皙的肤色 and freckles 雀斑 for example are more likely to use sunscreen As a result it may appear that sunscreen users get cancer more often The studies which generally relied on volunteers to recall their sunscreen use were also unable to prove how well the products had been applied said the 9 new study 43 The underlined word flaws in the 2nd paragraph most probably means A evidence B facts C faults D failures 44 People with fair skin and freckles A seldom use sunscreen B are more in danger of skin cancer C can be free from the harm of the sun D often expose themselves to the sun 45 We can learn from the passage that A sunscreen users get skin cancer more often B the volunteers have proved the effect of sunscreen C the new study was based on the experiences of volunteers D the number of skin cancer patients is increasing in America 46 Which of the following can be the title for this passage A Sunscreen to Prevent Skin Cancer B Sunscreen to Increase Skin Cancer C Skin Cancer
