Unit 3 Under the sea
Ⅰ阅读理解
A
（2018·四川成都高中毕业班检测）
Fans of the movie Finding Nemo may remember the terrifying fish that scares Dory and Marlin at the bottom of a trench.
But in reality this “monster”， a black seadevil， is only about 9 cm long，which would make it about a third of the size of Dory and potentially smaller than Marlin or Nemo.
While this inaccuracy may seem harmless， it could cause problems for future conservation efforts， as people are more likely to support conservation of adorable rather than scary-looking animals.
The black seadevil is just one of the mysterious “monsters”. From 2000 to 2010，scientists described about 1，200 new species in the Census of Marine Life. While this figure may seem astonishing， a further 5，000 individual dead creatures are in specimen（标本） jars， waiting to be described.
Specimens must be methodically collected， identified， and then the identity of new deep-water species must be confirmed.
If we call unusual deep-sea animals monsters，then we may harm their conservation as people are unlikely to be connected with them or care about saving them.
On the other hand， their rarity clearly makes them popular on social media sites. For other species， this has already resulted in increases in illegal trading for unusua l pets. Deep-sea species may potentially become illegally obtained specimens or food. Humans may end up eating these animals of the deep sea to extinction before their species are even known to science.
Every habitat on earth is interconnected， and whatever we as humans do has an influence on marine ecosystems. In reality， about 80% of our oxygen is produced by microorganisms（微生物） in the oceans. This makes our oceans both the lungs and lifeblood of our planet and we must all try harder to save them.
【解题导语】本文主要从电影里对深海物种的不准确认识，谈到了保护深海物种的重要性。
1.What can we know about the black seadevil in reality？
A.People benefit greatly from the oxygen produced by it.

4.What can we infer about those unusual sea animals？
A.They are the lungs and lifeblood of our planet.
B.Confirming their identity is very urgent for protection.

People who possess high self-esteem are able to commit better and produce a greater bond in relationships with others. Dr. Douglas feels that most people do not value themselves， but with love and self-respect anyone can be above normality and grasp success with the family， the office， or others.
We have become too reliant on intelligence， beauty， and money for our own self -esteem. The loss of esteem reduces the will and ability to set and reach goals.
In a series of reading Douglas teaches how to avoid negative statements， how to change them into self-facing behavior， and how to take charge of your mental attitude. Where other motivational and self-help work stops with the theoretical plan for success， Douglas takes everyday examples and puts them into his books. From raising ch ildren who believe in themselves to using self-esteem to help bridge the gap in the workplace， he gives readers concrete solutions to the problems that might ruin their interpersonal relations.
Self-esteem building comes from filling your thoughts with positive affirmations（肯定） and learning to react to failures with motivation instead of self-destruction. These lessons are valuable for anyone who feels that life is even slightly out of control. People who feel they have adequate esteem can learn to use it to make their success grander， faster， and more beneficial for others. Douglas approaches this process of self-development as a means of more than creating good things for the individual but also for setting up keys for influencing good things for others.
For more than thirty years， Dr. Douglas has addressed more than two million people on topics from time management to speaking effectively to raising drug-free children. He is the author of fifteen books， including How to Make a Habit of Succeeding.
【解题导语】本文主要讲述了自尊心强的优势以及如何培养自尊。
5.What can we infer from Paragraph One？
A.Most people behave well enough.
B.Self-respect means being above normality.
C.Self-esteem matters much.
https://www.360docs.net/doc/4b7119951.html,mitting better equals greater success.
C解析：推理判断题。根据第一段的整体内容可推知，自尊心很重要，故选C。
6.Why does Douglas put everyday examples into his books？
A.To be rel iant on self-esteem.
B.To set and reach goals.
C.To avoid negative thoughts.
D.To offer concrete solutions.
D解析：细节理解题。根据第二段的最后一句可知，Douglas把日常的具体案例写进自己的书里是为了给出具体的应对方法，故选D。
7.What does the author advise those whose life is slightly out of control to do？
A.Learn to be positive. B．Face it unmotivatedly.
C.Admit self-destruction. D．Ask for help.
A解析：细节理解题。根据第三段的前两句可知，对于那些感觉生活有些失控的人，作者建议他们肯定自己，积极应对，故选A。
8.What’s the most impor tant to be self-development？
A.Influencing the individual.
B.Influencing more people.
C.Gaining more benefits.
D.Speaking more effectively.
B解析：细节理解题。根据第三段的最后一句可知，自我发展最重要的是影响更多的人，故选B。
Ⅱ完形填空
（2018·甘肃第一次诊断）As a child， Jane was fond of animals. As a consequence，when she was growing up， all she ever heard was as follows，“Jane， you should be a（n） 1 Ｗ. You’re going to achieve great success in that field. That’s the very thing you should do in the future.” So when she got to the Ohio State University， she took biology， chemistry and some other 2 ， studying hard to be a vet.
Later on， she won a Rotary Ambassadorial Scholarship，which allowed her to spend her 3 year studying abroad in Manchester， England. Away from the family and the 4 from them， she found herself one day sitting at her desk， surrounded by biology books and staring out of the window， when it suddenly hit her：“I’m in total 5 Ｗ. I don’t want to be a vet！”
6 she thought back over all the things she’d done in her life and what had made her happy. And then it hit her—it was all of the youth leadership conferences that she had volunteered at
7 the communications and leadership courses she had taken as selective courses back at Ohio State. “How could I have been so
8 ？Here I am in my fourth year at school and just finally
9 that I’m on the wrong path. I just never took the time to 10 it until now，” she thought.

When 12 to Ohio State， she was 13 able to convince the administration to let her create her own program in “leadership studies”，14 it took her 2 years longer to finally graduate. She 15 to become a senior management adviser in leadership training and development
for the Pentagon. She 16 founded a drug-prevention organization that 17 the message，“Lead your own life with the skill and the 18 to say no.”
So， never 19 someone else’s dreams. If you limit your 20 only to what seems possible or reasonable， you disconnect yourself from what you truly want.

高考英语 实战演练专题阅读理解(610)
高考英语实战演练专题阅读理解（610） 《附详析》 (第6篇) July 21st,2007 was a typical English summer’s day — it rained for 24 hours! As usual, I rushed home from work at midday to check on the house. Nothing was amiss. By the time I left work at 5 pm, however，the road into our village was flooded. Our house had never been flooded but, as I opened the front door, a wave of water greeted me. Thank God the kids weren’t with me, because the house was 5 feet deep in water. We lost everything downstairs. And the plaster had to be torn off the walls, ceilings pulled down. At first we tried to push on through. We didn’t want to move the children out of home, so we camped upstairs. We put a sheet of plastic across the floor to protect us from the damp. But after three months, we felt very sick, so we moved to a wooden house in a park. The house was small, but at first we were all just delighted to be in a new place. Unfortunately, things took longer than expected and we were there for 10 months. The life there was inconvenient. What surprised me most was how much I missed being part of a community (社区). We had lived in a friendly village with good neighbours，and I’d never thought how much I’d miss that. Although our situation was very bad, it’s difficult to feel too sorry fo r yourself when you look at what’s happening elsewhere. I watched a news report about floods in Northern India and thought，“We didn’t have a straw hut(茅草房) that was swept away, and our house is still standing. We’re lucky.” We moved back home in August. With December coming，there’s still reconstruction work to be done, so it’s difficult to prepare for Christmas. But I can’t wait—I’m going to throw a party for our friends in the village to say thanks for their support. This year, I won’t need any gifts — living away from home for months has made me realize how little we actually need or miss all our possessions. Although we are replacing things, there’s really no rush—we have our home back, and that’s the main thing. [语篇解读] 洪水给生活带来了困难，但在灾害面前，也能获得更多对人生的认识。 5．W hat does the underlined word “amiss” in the first paragraph mean?
高考英语一轮阅读理解训练题_5
云南省曲靖市2014高考英语（阅读理解）一轮训练题（6）及答案阅读下列短文，从每题所给的四个选项（A、B、C、D）中，选出最佳选项. A Here's a familiar version of the boy-meets-girl situation. A young man has at last plucked up courage to invite a dazzling young lady out to dinner. She has accepted his invitation and he is overjoyed. He is determined to take her to the best restaurant in town, even if it means that he will have to live on memories and hopes during the month to come. When they get to the restaurant, he discovers that this beautiful creature is on a diet. She mustn’t eat this and she mustn't drink that. Oh, but of course, she doesn't want to spoil his enjoyment. Let him by all means eat as much fattening food as he wants: it’s the surest way to an early grave. They spend a truly memorable evening together and never see each other again. What a miserable lot dieters are! You can always recognize them from the sour expression on their faces. They spend most of their time turning their noses up at food. They are forever consulting calorie charts; gazing at themselves in mirrors; and leaping on to weighing-machines in the bathroom. They spend a lifetime fighting a losing battle against spreading hips, bigger tummies（肚子） and double chins. Some declare all-out war on FAT. Mere dieting is not enough. They exhaust themselves doing exercises, sweating in sauna baths, being massaged by weird machines. The really wealthy pay vast sums for “health cures”. For two weeks they can enter a nature clinic and be starved to death for a hundred dollars a week. Don’t think it’s o nly the middle-aged who go in for these fashions either. Many of these bright young things you see are living on nothing but air, water and the goodwill of God. Dieters undertake to starve themselves of their own free will; so why are they so miserable? We ll, for one thing, they’re always hungry. You can't be hungry and happy at the same time. All the horrible foods they eat leave them permanently dissatisfied. “Wonderfood is a complete food”, the advertisement says. “Just dissolve(溶解) a teaspoonful in wate r…”. A complete food it may be, but not quite as complete as a juicy steak. And, of course, they’re always miserable because they

高考英语阅读理解三篇
(A ) A coal-fire stove(炉灶)provided heating for Zhao Yaoqin's courtyard bungalow in a Beijing hutong all her life. This winter, however, the stove has disappeared from the 66-year-old's life, and an electric radiator takes its place beside her bed, a product of a government to use clean energy in the national capital. With the Olympics to be staged in Beijing next August, the city is determined to eliminate the use of coal within the Third Ring Road that circles the city before the Games. The project to replace the stoves with electric radiators has been part of the effort. When the city's four-month long heating season started on Thursday, coal-fired stoves, known as a big source of pollution in the big city, have disappeared from some 20,000 local households like Zhao's bungalow in the inner city "hutong" -- traditional alleyways(小巷) that date back centuries. "We used to boil water or bake bread on the stove," said Zhao, sounding sentimental(伤感) to the disappearance of the coal furnace from her life. Late in the 1990s, Beijing's air quality monitoring office found that the emissions(排放) of sulphur dioxide and carbon monoxide from the hutong areas have been higher than the city's average in winter, mainly because of the coal stoves. With the project to switch to clean energy for heating launched in 1999, the emission level of the two poisonous substances decreased by 42 percent and 44 percent, respectively, this year from 2001 levels. Zhao said the fee for electrical heat for the entire winter was usually around 2,400 yuan (US$323) per household. With the government's subsidy（补贴）, however, she only needed to pay about 500 yuan, nearly the same price as that for coal. 1．Zhao Yaoqin’ example in the passage is to tell us that_______. A.people in Beijing using electric radiators to welcome the Olympics. B.people in Beijing are doing something to protect the environment. C.hutongs in Beijing have a long history. D.People pay more money to use electric radiators than before. 2. The underlined word eliminate probably means________ A. cut down. B. increase. C. get rid of. D. replace 3. We can infer from the passage that ______ A. Zhao Yaoqin has a strong and deep emotion with the use of coal-fire stove. B. The government will pay most of the fee. C. The air of Beijing has been badly polluted since 1990s. D. The people do not use coal eight months in one year. 4. Which of the following is NOT true according to the passage? A. The clean air is important when the Olympics Games is held in Beijing. B. The success of the Olympics Games depends on the clean air. C. The government spare no effort to make the environment better. D. The emission level of poisonous substances will be low in 2008.
2012届高考英语实战演练专题阅读理解(101-105)《附详析》
2012届高考英语实战演练专题阅读理解（101-105）《附详析》 (第101篇) How Room Designs Affect Our Work and Feelings Architects have long had the feeling that the places we live in can affect our thoughts, feelings and behaviors. But now scientists are giving this feeling an empirical (经验的，实证的) basis. They are discovering how to design spaces that promote creativity, keep people focused, and lead to relaxation. Researches show that aspects of the physical environment can influence creativity. In 2007, Joan Meyers-Levy at the University of Minnesota，reported that the height of a room?s ceiling affects how people think. Her research indicates that higher ceilings encourage people to think more freely, which may lead them to make more abstract connections. Low ceilings, on the other hand, may inspire a more detailed outlook. In addition to ceiling height, the view afforded by a building may influence an occupant?s ability to concentrate. Nancy Wells and her colleagues at Cornell University found in their study that kids who experienced the greatest increase in greenness as a result of a family move made the most gains on a standard test of attention. Using nature to improve focus of attention ought to pay off academically, and it seems to according to a study led by C. Kenneth Tanner, head of the School Design & Planning Laboratory at the University of Georgia. T anner and his team found that students in classrooms with unblocked views of at least 50 feet outside the window had higher scores on tests of vocabulary, language arts and maths than did students whose classrooms primarily overlooked roads and parking lots. Recent study on room lighting design suggests that dim(暗淡的) light helps people to loosen up. If that is true generally, keeping the light low during dinner or at parties could increase relaxation. Researchers of Harvard Medical School also discovered that furniture with rounded edges could help visitors relax. So far scientists have focused mainly on public buildings. “We have a very limited number of studies, so we?re_almost_looking_at_the_problem_through_a_straw_(吸管)，” architect David Allison says. “How do you take answers to very specific questions and make broad, generalized use of them? That?s what we?re all struggling with.” [语篇解读]建筑师认为房子的设计可影响居住者的思想、情绪、行为，对此科学家进行了理论上的论证。 1. What does Joan Meyers-Levy focus on in her research?

【2019-2020】高考英语一轮阅读理解巩固练（1）（含解析）） 李仕才 A If you want to slow aging, you might want to eat less. This finding is good news---if you were a mouse. The researchers studied mice, not people. John Price and other researchers studied two groups of mice. One group was able to eat as much as it wanted. The researchers limited what the mice in the other group ate. Their diet had 35 percent fewer calories than the first group of mice. Price says the mice with the diet restrictions were “more energetic and suffered few er disease.” They were not just living longer but seemed to stay younger for a longer period of time. The researchers found that fewer calories slow down a natural mechanism in cells called ribosomes. Price explains that ribosomes are responsible for making important proteins in the cells. But with fewer calories, they slow down. This gives the cells more time to repair themselves. The researchers say ribosomes use from 10 to 20 percent of the cell’s energy to make those proteins. Price wrote that “because of this, it is impractical to destroy an entire ribosome” when it starts to break down. However, “repairing individual parts of the ribosome on a regular basis enables ribosomes to continue producing high quality proteins for longer than they would otherwise. This top quality production, in turn, keeps cells and the entire body functioning well.” “Food,” he said, “isn’t just material to be burned---it’s a signal that tells our body and cells how to respond.” Price said the findings help to explain how exac tly our bodies age. And this may “help us make more educated decisions about what we eat.” 1.What can we know about the mice with limited calories from the study? A. They can keep healthy easily B. They need more energy to be active C. They can look younger than they are D. They will live a longer life like humans
