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. 譯文： 全球變暖是我們在21世紀(jì)面臨的最嚴(yán)重的問題。大多數(shù)科學(xué)家認(rèn)為人類活動，而不是自然因素，是引起全球變暖的主要原因。中國和其他國家的人們也都意識到，在發(fā)展世界的同時我們也在毀壞我們居住的陸地。我們看到有時垃圾被扔進(jìn)提供飲用水的溪流，森林因人們的疏忽而起火。海灘、街道上是丟棄的垃圾。 1) Global warming 全球變暖 2) destroy the land 毀壞土（陸）地 3) throw into streams 扔進(jìn)小溪 4) be littered with 在……充滿垃圾 2. The more beautiful cars are produced, the more gases are poured into the air. More and more tall buildings are being built, but the waste from the factories has polluted the water, and the gases from the factories have poisoned the air. All of this pollution produces a lot of carbon dioxide which prevents heat from escaping. 譯文： 人們生產(chǎn)出越來越多的漂亮汽車，向大氣中排放著更多的廢氣。修建了越來越多的高樓大廈，但來自工廠的廢料污染了水，來自工廠的廢氣污染了空氣。所有這些污染都釋放出了大量的二氧化碳，阻止了熱量的釋放。 1) pour into 涌入 2) more and more 越來越多 3) prevent heat from escaping 阻止散熱 3. 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 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. 譯文： 太陽的射線給地球表面，海洋和陸地提供了熱量，使地球上的生命得以延伸。同時，一定數(shù)量的熱量釋放到外太空，這樣地球的溫度得以保持平衡?，F(xiàn)在由于大氣中二氧化碳的含量逐年增加，所以釋放的熱量也在逐年減少。在過去的一個世紀(jì)中，地球表面的溫度大幅度上升。全球變暖日趨嚴(yán)重，同時也帶來了許多副作用。 1) a certain amount of heat 一定數(shù)量的熱量 2) go into outer space 釋放到外太空 3) so that 以便于 4) the surface temperature of the earth 地球表面的溫度 5) have many side effects 有許多副作用 6) at the same time 同時 4. The side effects of global warming are surprising. A warmer global climate melts the ice caps and raises sea levels. Furthermore, it disturbs the weather and causes floods and storms. 譯文： 全球變暖的副作用令人警覺。地球氣溫上升使冰蓋融化，海平面上升。而且，它會擾亂天氣狀況，并引起洪水和暴風(fēng)雨。 5. What can we do to save our environments? First, we can plant more trees. Trees can take in carbon dioxide and then produce oxygen. Second, we have to find new power, coal and oil should be used 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. 譯文： 我們應(yīng)該做些什么來拯救我們的環(huán)境？首先，我們可以多種樹。樹木可以吸收二氧化碳并產(chǎn)生氧氣。其次，我們必須尋找新的能源。人們應(yīng)該盡可能少地燃燒煤和石油。因為這些能源會向大氣排放大量廢氣。我們應(yīng)該盡量使用太陽能、風(fēng)能、氫以及其他新的能源。最后，我們應(yīng)該成立環(huán)保小組，以告知所有人保護(hù)地球的重要性。 知識點： 1) plant more trees 多種樹 2) take in 吸收 3) be used as 作為……被使用 4) as little as possible 盡可能少 5) make use of solar energy 充分利用太陽能 6) wind power 風(fēng)能 7) some new sources of energy 一些新的能源 8) start environmental groups 成立環(huán)保小組 9) the importance of protecting the earth 保護(hù)地球的重要性 Unit 12 At The Zoo 預(yù)習(xí)導(dǎo)學(xué) （一）學(xué)習(xí)本單元要求大家掌握的詞匯、短語及句型： 單詞（課文中要求大家掌握的四會詞匯） officer, secretary, fisherman, postman, librarian, guard, soldier, engineer, director, zookeeper, kitchen, pay, type, letter, mail, island, care, creature, add, unpleasant, feed, condition, chore, joke, practice 短語：（根據(jù)課文的語言環(huán)境，寫出下列各短語的意思） 1) all kinds of weather 2) breathe fresh air 3) from door to door 4) make decisions 5) move around 6) watch the monkeys play on the rocks 7) sound like 8) self introduction 9) have a degree in the zoology 10) under one’s care 11) wild creatures 12) keep in good condition 13) teach the animals to do tricks 14) good practice for you 句型： 1) Some visitors expect that the animals here will know how to perform. 2) Why don’t you ask her to tell us something about her job? （二）總結(jié)一下職業(yè)名詞，并用英文解釋其工作內(nèi)容。 【模擬試題】（答題時間：60分鐘） 一、單項選擇 1.

The police said that they had disappeared during an adventure (冒險) 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 (鱷魚). 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 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 (地點) 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 article is probably taken from ___________. A. a newspaper B. a magazine C. a storybook D. a guidebook 36. Which word best describes the search of the three missing people? A. Helpless B. Hard C. Delightful D. Successful 37. Which of the following things wasn’t found by the police? A. A touring map. B. A photo of the travelers. C. The travelers’ radio. D. The travelers’ car 38. All the following are unanswered questions except_____________. A. why they left a photo behind B. why they came to this area C. why their Toyota was parked in the place D. why a cross was drawn on the map *B Where in the world can you take an hour’s train ride, and pass a 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 panies(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 bee 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. 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 pany 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 petition from other states C. its movie panies are in need of young stars D. the state hasn’t put a development plan into action 41. Which of the following seems to be a threat（威脅）to Hollywood？ A. The use of modern cameras and other equipment B. The interest of middle-aged film stars C. The making of TV series like Dynasty D. The 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, monly 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 (發(fā)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(白皙的膚色) 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 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 Caused by Sunscreen D. Skin Cancer Caused by Freckles **四、根據(jù)對話內(nèi)容，用方框中所給詞的適當(dāng)形式填空。（其中有一詞多余） follow, bad, first, sports, easy, walk, child, kind What’s the coolest kind of transportation (交通工具 ) for middle school students back from the winter holidays? A racing bike? A car? No, it’s a special 1 of shoe called Heelys (暴走鞋). Heelys look just like mon 2 shoes, but they have a wheel hidden in the heel (鞋跟). So instead of 3 , kids can “fly” around in them. “Wearing Heelys is fun and cool,” said Wu Peng, a boy who wore them on his 4 day back at No. 6 Middle School in Beijing. Wu Peng said he loves the shoes so much that he wears them wherever he goes. Sometimes he even 5 his parents’ car to the supermarket on his Heelys! Other students think these are very cool, but some haven’t been so lucky with their Heelys. It’s reported that some 6 have fallen down while using these shoes, and some have been hurt. “Heelys wheels are on the heels of the shoes, so it’s easy to fall,” said Liu Rui, a doctor at the Hong Kong International Medical Clinic, Beijing. Even 7 , Liu said, “Wearing Heelys for a long time could stop young people from developing their ankles (腳踝) and legs.” 五、根據(jù)中文意思完成句子： 1. 我想不會下雨，不要帶傘了。 ____________________________it will rain; leave your umbrella behind. 2. 我的手機(jī)壞了，沒有收到你的短信。 ____________________________ with my mobile phone.
