Unit 3 Under the seaⅠ.阅读理解(2018安徽合肥第二次质量检测)It’s not every day that the United States history mixes with microbes (微生物) in the soil.But when the grassland on the National Mall in Washington,D.C.was replaced,it offered scientists the opportunity to study changes in the soil beneath.T h e w o r k f o c u s e d o n t h e b a c t e r i a p r e s e n t i n t h e s o i l.T o t h e researchers’ surprise,the communities of microbes did not change a lot before and after the replacement.These communities in the soil are known as the soil microbiome (微生物群).“My lab is interested in how microbes can move around in the environment,and how they change and adapt as a result of this movement,” explains Jo Anne Crouch,the lead author of the study.“We thought that the new ‘imported’ turf (草皮) from New Jersey would introduce different communities of bacteria to the National Mall.However,we found that they weren’t significantly different.”Crouch’s work focused on turf grass,defined as a large area of green grass.It is made up of the grass,its roots,and the soil and microbes found with them.Think of the soil microbiome as similar to the collection of microbes found in the human body.When the microbes are out of balance,it can make someone sick.Crouch says it’s the same for the soil microbiome.Many of the worst diseases in crops or other environments are linked with changes in the soil microbiome.Additionally,Crouch says that even though the changes between the soils were small,scientists are also starting to appreciate that sometimes a really important microbe is a rare one.This means it would be hard to observe but could greatly affect how the groups function as a whole.“Agricultural areas and other natural spaces are highly and easily hurt by negative changes,” she says.“Microbiomes offer an almost entirely new opportunity to influence interactions among plants and microbes to improve plant productivity and health.”1.Why did the researchers feel surprised when they focused on the bacteria in the soil?A.More bacteria appeared in the soil.B.Microbes were replaced obviously.C.Soil microbiome almost remained stable.D.The soil microbiome damaged the environment.2.By studying the turf grass,what did Crouch and her team find?A.Microbes grew faster in their own community.B.Soil microbiomes were different in different places.C.Turf grass adapted to the environment nearby very soon.D.Similar communities of bacteria were brought by turf grass.3.Why did the author mention the microbes in the human body?A.To indicate the two play a similar role.B.To prove they are both the causes of diseases.C.To examine the environments people live in.D.To analyze the changes of human microbes.4.What does Crouch mean in the last paragraph?A.Microbes are still as hard to observe as before.B.Studies on microbiomes can be beneficial to agriculture.C.Scientists are still puzzled about the effect of microbiomes.D.Too many microbiomes in the soil mean no harm to plants.语篇解读:正如人体的微生物群落对人体的健康有影响一样,土壤的微生物群落也会对植物的产量和健康产生影响。
答案及剖析:1.C 细节理解题。
根据第二段中的To the researchers’ surprise,the communities of microbes did not change a lot before and after the replacement.These communities in the soil are known as the soil microbiome.可知,令研究者惊讶的是土壤微生物群落几乎保持稳定。
2.D 细节理解题。
根据第三段中的We thought that the new ‘imported’ turf from New Jersey would introduce different communities of bacteria to the National Mall.However,we found that they weren’t significantly different.可知,通过研究草皮,克劳奇和她的团队发现新移植过来的草皮带来的微生物群落与原来的微生物群落类似。
3.A 推理判断题。
根据第五段第一句Think of the soil microbiome as similar to thecollection of microbes found in the human body.及该段后面的内容可推知,作者提及人类体内的微生物是为了表示这两种类型的微生物扮演着类似的角色。
4.B 推理判断题。
最后一段提到微生物群落提供了一个提高庄稼产量、促进植物健康的全新机会。
由此可知,对微生物群落的研究对农业是有益的。

Unit 3 Under the seaⅠ.阅读(2019陕西部分学校检测) Scientists are preparing to launch the world’s first machine to clean up the planet’s largest mass of ocean plastic.The experts believe the machine should be able to collect half of the detritus in the patch—about 40,000 metric tons—within five years.In the past few weeks they have been busy welding together giant tubes that will sit on the surface of the sea and form the skeleton of the machine,creating the largest floating barrier ever made.The system,originally dreamed up by Mr.Slat,will be shipped out this summer to the Great Pacific Garbage Patch,between Hawaii and California,and which contains an estimated 1.8 trillion pieces of plastic.It will be the first ever attempt to tackle the patch since it was discovered in 1997.Mr.Slat was 16 and still at school when he was diving in Greece and first saw for himself the amount of plastic polluting the sea.“There were more bags than fish down there,” he recalls.Two years later he came up with a solution,quit university after six months and set up The Ocean Cleanup as a company.Mr.Slat,23,says the first plastic to arrive on shore will be a major milestone.“We as a humanity created this problem,so I think it’s our responsibility also to help solve it,” he said.The Great Pacific Garbage Patch (GPGP) spans 617,763 sq miles—more than twice the size of France,and contains at least 79,000 tons of plastic,research found last month.Most of it is made up of “ghost gear”—parts of abandoned and lost fishing gear,such as nets and ropes—often from illegal fishing vessels.Ghost gear kills more than 100,000 whales,dolphins and seals each year,according to scientific surveys.Seabirds and other marine life are increasingly being found dead with stomachs full of small pieces of plastic.Creatures eat plastic discarded in the sea thinking it’s food but then starve to death because they are not feeding properly.Others are trapped and die of starvation or are strangled or suffocated by ghost gear.1.What does the underlined word in the second paragraph probably mean?A.Waste.B.Ocean.C.System.D.Machine.2.According to the passage,most of the Garbage in Pacific is made up of .A.fishing vesselsB.dolphins and sealsC.giant tubesD.abandoned fishing gear3.Why do some creatures in the Great Pacific Garbage Patch die of starvation?A.Because they were killed by ghost gear.B.Because they were suffocated by ghost gear.C.Because they don’t like eating plastic.D.Because they are not feeding properly.4.What is the main idea of the passage?A.A report about the death of marine life.B.News about the first machine to clean up ocean plastic.rmation about ocean plastic.D.The reason for inventing a machine.语篇解读:本文是一篇说明文,主要介绍了世界首台海洋塑料清理机将启用,尝试处理太平洋塑料垃圾。

课时达标(三十三) Unit 3 Under the sea(见学用课时P77)Ⅰ 阅读理解Ain our oceans.Both mammals and fish benefit from the clean ocean. It is reported that more than 8 million tons of plastic end up in our oceans every year, and nearly half of the plastic we produce is singleuse only.This shoe brand, however, is riding the wave of change and is on a mission to help clean up our waters and rid the sea of plastic bottles that can take up to 400 years to break down. Vivobarefoot's newest footwear uses recycled plastic materials and has created an education program that spreads awareness about how harmful plastic is for sea life.Every pair of shoes is made up of 17 plastic water bottles taken from the ocean and turned into a sustainable, comfortable pair of shoes, which are also healthy for your feet. And while not everyone can take part in ocean cleanups, choosing little ways we can give back to our planet goes a long way.Vivobarefoot's new products include a variety of highperformance styles such as casual sneakers, running shoes, and hiking boots. The brand hopes that its latest initiative(新方案) will help lessen the indifference to pollution and how harmful it is for all living beings.In the future, Vivobarefoot hopes to increase their production of shoes created from sustainable materials, and thankfully, it is now one of many brands that aim to increase environmentalism and educate communities on how global warming affects everyone.This year, they'll add more recyclable and traceable materials into more than half of their production line, and they have plenty of creative developments in the works as well.The shoes also have a health benefit. Based on the concept that wider, minimallydesigned shoes enable our foot to function at maximum potential, wearers also experience better balance and sensory input.语篇导读本文主要介绍了一家利用海洋中的废弃塑料瓶制作鞋子的公司。

选修7 Unit 3 Under the sea李仕才一、阅读理解A recent survey in the United States showed that the average family spent more money on its pets than on its children. Although rather shocking, it should not surprise anyone who has seen the doggy parlours(客厅) where loved pets rest. Are Americans unique in treating their little friends in this way? No, the English, too, pay more attention to their pets.This can clearly be seen when we look at pet foods，which often contain more vitamins than human food. They certainly cost much. Last year the British public spent two hundred million pounds on pet food alone, to say nothing of veterinary bills or animal furniture. It is difficult not to feel angry about this when considering what the same amount could do for victims of starvation and poverty, so it’s not unusual for me to get hot under collar when I read an old man left all his money to his dog instead of his children.There are a variety of reasons why I find pets-raising alarming. They cause physical problems. An example of this is New York where they have great difficulty getting rid of the mess that dogs leave on the streets. Many people find this funny, but in a number of large cities it is a major problem. Animals can cause disease, too. It is the threat of babies — a disease with no known cure.Another problem is the carelessness of pet owners. Most little children want a dog or a cat，and they continually push their mothers and fathers until they get one. It is only when the ＂sweet little thing＂ has been brought home that the parents realize how much time and money must be spent on ＂Rover＂ or ＂Bonzo＂. Then they just abandon it. As a result, they are allowed to run free. English farmers lose hundreds of sheep a year, killed by someone’s pet and you must have read of children being hurt by some pets of their own.Lastly, I would only suggest that we have got our priorities wrong and that something should be done about it. In my view, it’s time we stopped being sentimentalabout pets. I can see no reason why we should get upset when animals are cut up for medical experiments. This will lead us to discovering cures for serious human diseases, then I say,＂keep cutting!＂1. The doggy parlours are mentioned in the 1st paragraph to show ________.A. what costly lives the pets are livingB. where Americans keep their petsC. why children love their pets so muchD. how much pets depend on their masters2. In the second paragraph ＂to get hot under the collar＂ probably means ________.A. getting quite hotB. becoming excitedC. feeling extremely angryD. receiving a fashionable shirt3. According to the author, in which field can animals be most useful?A. Food.B. Sports.C. Entertainment.D. Medicine.4. What is the author’s attitude towards pets-raising?A. Sympathetic.B. Opposed.C. Pitiful.D. Supportive.【文章大意】这是一篇议论文。

Unit 3 Under the sea一、阅读理解。
Wouldn’t it be wonderful to travel to a foreign country without having to worry about the headache of communicating in a different language?In a recent article from The Wall Street Journal, technology policy expert Alec Ross argued that，within a decade or so, we’ll be able to communicate with one another via small earpieces with builtin microphones. That’s because technological progress is extremely rapid.It’s only a matter of time. Indeed, some parents are so convinced that this technology is imminent that they’re wondering if their kids should even learn a second language.It’s true that an increase in the quantity and accuracy of the data loaded into computers will make them cleverer at translating “No es bueno dormir mucho” as “It’s not good to sleep too much”. Replacing a word with its equivalent(对应词) in the target language is actually the “easy part” of a translator’s job.But even this seems to be a discouraging task for computers.It’s so difficult for computers because translation doesn’t —or shouldn’t—involve simply translating words, sentences or paragraphs. Rather, it’s about translating meaning. And in order to infer meaning from a specific expression, humans have to interpret a mass of information at the same time.Think about all the related clues that go into understanding an expression: volume, gesture, situation, and even your culture. All are likely to convey as much meaning as the words you use.Therefore ，we should be very skeptical of a machine that is unable to interpret the world around us. If people from different cultures can offend each other without realizing it, how can we expect a machine to do better? Unless engineers actually find a way to breathe a soul into a computer, undoubtedly when it comes to conveying and interpreting meaning using a natural language, a machine will never fully take our place.【解题导语】技术专家说随着技术的进步，即时翻译机器将在大约十年内出现在市场上。

They were there all the time: early morning, noon, and evening. There were little old ladies in gray sweats, young couples in Adidas shoes, middle-aged men with red faces. “Come on!” My friend Alex encouraged me to join him as he jogged by my house every evening. “You’ll feel great.”Well, I had nothing against feeling great and if Alex could jog every day, anyone could. So I took up jogging seriously and gave it a good two months of my life, and not a day more. Based on my experience, jogging is the most overvalued form of exercise around, and judging from the number of the people who left our neighborhood jogging army. I’m not alone in my opinion.First of all, jogging is very hard on the body. Your legs and feet a real pounding（追击）ruining down a road for two or three miles. I developed foot, leg, and back problems. Then I read about a nationally famous jogger who died of a heart attack while jogging, and I had something else to worry about. Jogging doesn’t kill hundreds of people, but if you have any physical weaknesses,jogging will surely bring them out, as they did with me.Secondly, I got no enjoyment out of jogging. Putting one foot in front of the other for forty-five minutes isn’t my idea of fun. Jogging is also a lonely pastime. Some joggers say, “I love being out there with just my thoughts”Well, my thoughts began to bore me, and most of them were on how much my legs hurt.And how could I enjoy something that brought me pain? And that wasn’t just the first week: it was practically every day for two months. I never got past th e pain level, and pain isn’t fun. What a cruel way to do it! So many other exercises, including walking, lead to almost the same results painlessly, so why jog?I don’t jog any more, and I don’t think I ever will. I’m walking two miles three times a wee k at a fast pace, and that feels good. I bicycle to work when the weather is good. I’m getting exercise, and I’m enjoying it at the same time. I could never say the same for jogging, and I’ve found a lot of better ways to stay in shape.46. From the first paragraph, we learn that in the writer’s neighborhood ______.A. jogging became very popularB. people jogged only during the daytimeC. Alex organized an army of joggersD. jogging provided a chance to get together47. The underlined word “them”(Paragr aph 3) most probably refers to _____.A. heart attacksB. Back problemsC. famous joggersD. physical weaknesses48. What was the writer’s attitude towards jogging in the beginning?A. He felt it was worth a try.B. He was very fond of it.C. He was strongly against it.D. He thought it must be painful.49. Why did the writer give up jogging two months later?A. He disliked doing exercise outside.B. He found it neither healthy nor interesting.C. He was afraid of having a heart attack.D. He was worried about being left alone.50. From the writer’s experience, we can conclude that______.A. not everyone enjoys joggingB. he is the only person who hates joggingC. nothing other than jogging can help people keep fitD. jogging makes people feel greater than any other sport.B篇51. Who would miss his or her family most?A. JaimeB. JayneC. MikoD. Paola.52. Which of the following people would feel most uncomfortable without the news media?A. Steve.B. JaimeC. Roger.D. Tomas53.
