1、教材全解高中英语选择性必修第二册人教版语境记单词UNIT 1 SCIENCE AND SCIENTISTS1 Cholera is an infectious disease caused by germs. People who are infected with this disease will suffer from severe diarrhoea，dehydration and even death. As a young doctor，John Snow felt a little frustrated at first，but he was determined to defe
2、at “ King Cholera” once and for all. There were then two contradictory theories to explain how cholera spread. Snow subscribed to the correct theory that cholera was caused by an infection from germs in food or water. But Snow needed proof and findings. It happened that cholera broke out in London i
3、n 1854，and Snow began to investigate. He discovered that there were multiple deaths in some households near the water pump in Broad Street. This showed there was a link between the cases of cholera and the water. Snow suspected that the water pump was to blame，so he had the handle of the water pump
4、removed. Thanks to Snows intervention，people began to drink pure water instead of raw water. Thus，there was a substantial decrease in the threat of cholera. Furthermore，in his use of maps and statistics，Snow transformed the way scientists study diseases. His thinking and concept on disease were quit
5、e novel at that time. Therefore，Snow is considered the father of modern epidemiology.霍乱是一种由细菌引起的传染病。感染这种疾病的人会严重 腹泻、脱水甚至死亡。作为一名年轻的医生，约翰 斯诺一开始感到有点沮丧，但他决心彻底击败“霍乱王”。当时有两种截然不同的理论来解释霍乱是如何传播的。斯诺赞同正确的理论，即霍乱是由食物或水中的细菌感染引起的。但斯诺需要证据和调查结果。1854 年伦敦恰巧暴发了霍乱，斯诺开始调查。他发现宽街水泵附近的一些住户有多人死亡，这说明霍乱病例与饮用水有关联。斯诺怀疑水泵是罪魁祸首，于是他
6、让人把水泵的把手拆掉了。多亏了斯诺的干预，人们开始饮用纯净水而不是原水。因此，霍乱的威胁大幅 降低。此外，斯诺利用地图和统计数据，改变了科学家研究疾病的方式。他对疾病的思考和观念在当时是相当新颖的。因此，斯诺被认为是现代流行病学之父。2 Doctors use microscopes to observe cells，germs， viruses or proteins in cells，while astronomers look at stars and study astronomy through telescopes. A theory may be abstract，but res
7、earch work needs to have a solid，concrete or vivid theoretical framework. Besides John Snow，it is worth mentioning Qian Xuesen，the father of Chinas aerospace industry. He was an outstanding， gifted and patriotic scientist. At first，he studied railway mechanical engineering. In order to defend Chinas
8、 airspace，he shifted his major to aviation. While studying in the United States，Qian Xuesen was a graduate assistant，studying jet and rocket technology. After returning to China，he was put in charge of developing Chinas rocket science and its space and missile programme. Under Qians leadership，China
9、s aerospace industry made steady progress and achieved initial success. Now lets change the subject. Here is a picture of a brilliant rainbow after a heavy rain. There is a man standing over there. The rainbow casts different shadows of the man. Above all，the moon is hanging in the sky，but the sun h
10、as not yet set. Can you find fault with this picture?医生用显微镜观察细胞、细菌、病毒或细胞中的蛋白质，而天文学家则用望远镜观察星体和研究天文学。理论可能是抽象的， 但研究工作需要有一个坚实、具体或生动的 理论框架。除了约翰 斯诺，值得一提的是“中国航天之父”钱学森。他是一位杰出的、有天赋的、爱国的科学家。起初，他学习铁道机械工程。为了保卫中国的领空，他转到了航空专业。在美国留学期间，钱学森是一名研究生助理，研究喷气式飞机和火箭技术。回国后，他被任命负责发展中国的火箭科学及其太空和导弹项目。在钱学森的领导下，中国航天事业稳步发展，初见成效。现
11、在咱们换个话题吧。这是一幅大雨过后的绚丽的 彩虹图。有一个人站在那边。彩虹 投射出这个人不同的影子。尤其是，天空中挂着月亮，但太阳还没有落山。你能找出这幅画的错误吗？UNIT 2 BRIDGING CULTURES1 My friend Xie Lei recalled her complex experience of studying abroad. Xie Lei originally studied for a business qualification at a university in China. She is an ambitious girl，and her ambiti
12、on is to set up a business back in China after graduation. She chose to live with a host family for her adaptation to the new culture. It was a comfort for her to have a second family. Her college tutor was very strict and advised her to participate in class activities. For example，she should speak
13、up in class or give presentations，not cite others opinions. She was engaged in British culture and involved in social activities，thus acting as a cultural messenger. She knew that much exposure to another culture could give her great insights into the world. At first，she felt culture shock from a fo
14、reign country，and had an overwhelming homesickness. But later she stepped out of her comfort zone and felt much more at home. She became more motivated. Xie Leis advisor talked to her about maintaining reasonable expectations when studying abroad. Her motivation to study abroad became more clear，and
15、 she even wanted to be an applicant for a job at a foreign firm. However，she was looking forward to her early departure from the UK.我的朋友谢蕾回忆起她复杂的留学经历。谢蕾最初在中国一所大学攻读商科。她是个有抱负的女孩，她的志向是毕业后回国创业。为了适应新的文化，她选择住在寄宿家庭。有了第二个家庭对她来说是一种安慰。她的大学导师非常严格，建议她参加班级活动。例如，她应该在课堂上大声发言或作报告，而不是引用别人的观点。她融入英国文化，参加社交活动，因此充当着文化使者
16、的角色。她知道，多接触另一种文化可以让她对世界有深刻的了解。一开始，她感受到了异国的文化冲击， 产生了一种强烈的 乡愁。但后来她走出了自己的舒适区，感觉更自在了。她变得更有动力了。谢蕾的导师跟她谈了在留学时要保持合理的 预期。她出国留学的动机变得更加明确，她甚至想申请到外企工作。然而，她期待着早日离开英国。2 In recent years，there has been a dramatic increase in the number of people studying abroad， but there exist some disadvantages. Tuition and livi
17、ng expenses are higher than at home and could end up costing an arm and a leg， far more than the household budget. Another factor is the tremendous life pressure. Some students are not mature enough to behave well in new surroundings. They cant grasp the local customs. Some students may feel depress
18、ed. Now，Chinas education is booming. More and more young students choose to study in China to make contributions to and strengthen their motherland in the future. No one can deny the fact that studying abroad has its disadvantages. But still some people are optimistic about it. As far as they are co
19、ncerned，studying abroad helps to gain and improve our general competence. Cooperating with people from diverse cultural settings helps us view the world from different angles. Chinas global outlook，with projects such as the Belt and Road Initiative，has helped us make connections across the world. Ch
20、ina needs cultural envoys as well as more talented young people with a global perspective who are highly competent with languages. Both sides sound logical. Which idea would you probably side with? As far as I know，studying abroad doesnt always bring good outcomes. In summary，I sincerely hope that p
21、arents will take this issue seriously.近年来，出国留学的人数急剧增加， 但也存在一些弊端。学费和生活费都比国内要高，最终可能要花掉一大笔钱，远远超出家庭 预算。另一个因素是巨大的生活压力。有些学生还不够成熟，在新的环境中表现不好。他们领会不了当地的风俗习惯。一些学生可能会感到沮丧。现在，中国的教育正在蓬勃发展。越来越多的青年学生选择在国内学习，在将来为祖国作出贡献，让国家更加富强。没有人能否认出国留学有它的弊端。但仍有一些人对此持乐观态度。在他们看来，出国留学有助于获得和提高我们的综合能力。与来自不同文化背景的人合作有助于我们从不同的角度看待世界。以“一带
22、一路”倡议等项目为代表的中国全球观，帮助我们与世界各国建立联系。中国需要文化使者，也需要更多具有全球视野、语言能力强、有才能的年轻人。双方听起来都很合理。你可能支持哪一种观点？就我所知，出国留学并不总是带来好的结果。总之，我真诚地希望家长们认真对待这个问题。UNIT 3FOOD AND CULTURE1 Prior to discussing food and culture，lets talk about the cuisine and recipes. Both Western and Chinese dishes may consist of these ingredients， suc
23、h as onion，garlic，cabbage，bean curd， chilli，etc. They contain a lot of vitamins and fibre. Meat includes pork，red braised pork，lamb，lamb kebabs，bacon，ham，sausage，haggis and so on， which contain large quantities of fat and calories. In addition，there are some other ingredients， such as soy sauce，vine
24、gar，olive oil，pepper and peppercorns. Food includes dairy products， buns，desserts，dim sum and so on. Generally speaking，there are different categories of cuisines all over the world.在讨论饮食和文化之前，我们先来谈谈烹饪和食谱。西餐和中餐都可能含有这些配料，如洋葱、大蒜、卷心菜、豆腐、辣椒等。它们含有大量的维生素和纤维。肉类包括猪肉、红烧肉、羊肉、烤羊肉串、熏猪肉、火腿、香肠、羊杂碎肚等，都含有大量的脂肪和卡路里。
25、此外，还有一些其他佐料，如酱油、醋、橄榄油、胡椒粉和胡椒粒。食物包括奶制品、圆面包、甜点和中式点心等。一般来说，世界各地有不同种类的菜肴。2 Madam Wang，a member of China Cuisine Association，works in our school canteen. She used to be a chef in a hotel cafeteria. She is elegant， modest with a stable temper. She can make exceptional desserts. She is a somewhat bold chef
26、，making dough into various shapes，slicing it into thin slices or stuffing it into different molds. She has her own tricks of the trade，so she makes her own brand of desserts，served with pearls and figs. She is overall a vegetarian，consuming a minimum of fat each day. She always eats or drinks in mod
27、eration，but never eats junk food. She also teaches us how to eat. She says one fundamental factor of an ideal diet is to chew slowly. Consistent eating habits are better for our health. This is true regardless of how healthy the rest of our diet might be.王女士，中国烹饪协会会员，在我们学校食堂工作。她曾在一家酒店的自助餐厅当过厨师。她举止优雅
28、、谦虚、稳重。她能做出特别的 甜点。她是一个有点 大胆自信的 厨师，把生面团做成各种形状，切成 薄片，或者塞进不同的模具里。她有自己的行业诀窍，所以她做出了自己品牌的甜点，配上珍珠和无花果。她总体上是一个素食者， 每天摄入 最少量的脂肪。她总是适度饮食，从不吃垃圾食品。她还教我们如何吃。她说，理想饮食的一个基本要素就是细嚼慢咽。连续的饮食习惯对我们的健康更有益处，不管我们饮食的其他方面有多健康，这都是正确的。UNIT 4JOURNEY ACROSS A VAST LAND1 Two Chinese girls arrived in Vancouver by commercial airline
29、. There they took a pleasant boat ride out into the bay and later visited an island with wonderful shops selling crafts and antiques. The next morning，the two girls arose early to take the train to Lake Louise，passing through the massive mountains and forests. The blue water in Lake Louise literally
30、 took their breath away with its exceptional beauty. Then they took a coach bound north through the Rockies to Jasper. The awesome scenery，spectacular mountain peaks and forests made them excited. One highlight of their trip was seeing many different creatures，including deer， mountain goats，and even
31、 a grizzly bear. Their first stop was Edmonton，the centre of Canadas oil and gas drilling industry. The city is freezing cold in winter but it is home to many shopping malls. Crossing the great Canadian Prairie and a bunch of farms，they did not anticipate seeing such an open country. As the train th
32、undered on towards the southern border，they opened the curtains and saw frost on the ground. Their trip from Vancouver to Toronto had taken a duration of four days.两个中国女孩乘坐商业航空公司的飞机抵达温哥华。在那里，她们乘船愉快地驶入海湾，后来参观了一个岛屿，岛上有很不错的出售工艺品和古董的商店。第二天早上，两个女孩早早起床，坐火车去路易斯湖，途经巨大的群山和森林。路易斯湖湛蓝的湖水异常美丽，令她们真正地 惊叹不已。然后她们乘长途
33、汽车向北穿过落基山脉到达贾斯珀。令人惊叹的 风景，壮观的山峰和森林，让她们兴奋不已。她们此行的一大亮点是看到了许多不同的生物，包括鹿、山羊，甚至一只灰熊。她们的第一站是埃德蒙顿，加拿大石油和天然气钻探工业的中心。这个城市冬天极冷，但它是许多购物中心的所在地。她们穿越加拿大大草原和成片的农场时，没有预料到会看到这样一个开放的国家。火车轰鸣着驶向南部边境，她们拉开窗帘，看见地面上有霜。她们从温哥华到多伦多的旅行持续了四天。2 My friend is a photographer with a French accent. He is enrolled in an English tutoring
34、 class to learn English idioms，but the result is often contrary to his wishes. One day at dusk he was staying in a hotel. He heard someone on the upper floor shout “Look out!” He put his head out of the window at once. As a result，a basin of water poured down on his head. He was astonished. Anyhow，h
35、e felt he was coherent. “English is so strange that look out means not looking out，”he said to himself. Once he saw an advertisement that said，“Our company owes a great deal to our customers.” He thought the company was in deep debt. In fact， its a way for the company to express their thanks to the
36、customers. He proceeded alongside the cobblestone shore，past a quarry，and finally arrived at the harbour. He took some pictures of a steel bridge in the mist. He came back late and had some toast for dinner.我朋友是一个有法国口音的摄影师。他报名参加了一个英语辅导班，学习英语习语，但结果往往事与愿违。一天傍晚，他住在一家旅馆里。他听到楼上有人喊“小心！” 他立即把头伸出窗外。结果，一盆水倒在
37、了他的头上，他很惊讶。不管怎样，他觉得自己是有道理的。他自言自语地说：“英语太奇怪了，向外看就是不要向外看。” 有一次，他看到一则广告，上面写着“我们公司非常感激我们的顾客”。他认为该公司负债累累。事实上，这是这个公司向顾客表达谢意的一种方式。他继续 沿着 铺有鹅卵石的 海岸 前行，经过一个采石场，最后来到港口。他在雾中拍了几张钢桥的照片。他回来得很晚，晚饭吃了些烤面包片。UNIT 5 FIRST AID1 My fellow classmate gave me a manual and a leaflet about first aid. They introduced many pract
38、ical first aid techniques. The skin is the largest organ of your body. It acts as a barrier against disease，toxins，and the suns rays. It gives you your sense of touch. If your skin is burnt by radiation or acids，you feel much pain，especially when you receive an electric shock. Burns are no minor inc
39、idents. If the burn surface is red and swollen with blisters，you should work as a paramedic and provide urgent treatment to ease the pain. You can wrap the burnt area with a loose clean fabric. If every layer of the skin is affected or nerves underneath are damaged，the victim must be taken to the ho
40、spital immediately. Here are some other first aid cases. What if someone swallows a chemical? What if someone slips in the bathtub? What do you do if an elderly man falls on the carpet? What do you do when you get bitten by a mosquito? What if your classmate sprains his ankle and bleeds? And what do
41、 you do when you hear a drowning man screaming? You might say， “I dont panic. Ill give first aid，like putting in an IV needle，performing mouth-to-mouth rescue breathing and checking his vital signs. Also， I will call emergency services without delay and try to explain to the operator until the ambul
42、ance arrives.”我的同学给了我有关急救的一本手册和一份宣传单。它们介绍了许多实用的急救方法。皮肤是人体最大的器官。它是抵御疾病、毒素和阳光的屏障。它给你触觉。如果你的皮肤被辐射或酸物质灼伤，你会感到很痛，尤其是当你受到电击的时候。烧伤不是小事。如果烧伤表面红肿并带有水疱，你应该充当一名护理人员，提供紧急处理，以减轻疼痛。你可以用一块干净透气（宽松）的 布把烧伤部位包裹起来。如果皮肤的每一层都受到了影响或下面的 神经受到了损害， 那么，伤者必须立即送往医院。这里还有一些其他急救案例。如果有人吞下了化学物质怎么办？如果有人在浴缸里滑倒了怎么办？如果一个老人摔倒在地毯上，你该怎么做？当你
43、被蚊子叮咬时，你会怎么做？如果你的同学扭伤 脚踝 流血了该怎么办？当你听到一个溺水的人尖叫时你会怎么做？你可能会说，“我不惊慌。我会实施急救，比如打静脉注射针、进行口对口人工呼吸并检查生命体征。此外，我还会毫不迟疑地打电话给急救中心（应急服务机构），并尽力向接线员解释情况，直到救护车到来。”2 Once，I was having dinner in a restaurant. I had my dinner interrupted when I heard someone screaming from another table. A fellow diner at the restauran
44、t was choking on some steak. He was now holding his throat with his face turning red，while his desperate friends were slapping him on the back. I went over to help the diner to his feet. Then I used the Heimlich manoeuvre. I stood behind him，made a fist with one hand，grabbed my fist with the other h
45、and tightly，and then pushed up and into his stomach in one motion. I continued doing this until the obstruction was forced out. If he had been a small child，I would have laid him face down on my lap so that he couldnt collapse. We have a duty to look after one anothers welfare. How could I justify s
46、tanding by and doing nothing? Recently I was out of shape. I always ate more and slept in. I stayed in a hospital ward for two weeks. The doctor suggested that I should get a gym membership and work out at the gym in the suburbs.有一次，我在一家餐馆吃饭。当我听到另一张桌子上有人尖叫时，我的晚餐被中断了。餐馆里的一位用餐者被一些牛排 噎住了。此时他扼住自己的喉咙，脸涨得通红， 而他绝望的朋友们则在拍打他的后背。我走过去帮助用餐者站了起来。然后我采用海姆立克急救法。我站在他身后，一只手握拳，另一只手紧紧 抓住我的拳头，然后快速地向上向内推压他的腹部。我持续这样做， 直到阻塞物被排出。如果他是个小孩子，我会把他脸朝下放在我的膝盖上，这样他就不会倒下。我们有责任照顾彼此的健康。我怎么能有理由袖手旁观而什么也不做呢？最近我的身体不好，我总是吃得多， 起得晚。我在医院病房住了两个星期。医生建议我办个健身会员，在郊外的健身房锻炼。
