一、高中英语阅读理解科普环保类
1．犇犇阅读下面短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。

While every dog owner knows their dogs can read their moods perfectly, scientists have always been a little doubtful. Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria, we finally have some convincing evidence.
For their study, biologist Corson Miller and his team exposes eleven selected dogs to digital images of women that were either angry or happy. Half the dogs were rewarded for touching the screen when shown a happy face, while the other half got their treat for selecting those that appeared angry.
Interestingly, the dogs were not provided with the entire face. Some dogs were shown only upper halves while the others observed lower halves. That's because the scientists believe humans show their emotions on their entire face.
After some training like how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions, the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face. The researchers concluded the dogs were smart enough to read human emotions.
They also found those being trained to read angry expressions took a longer time to learn. They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly. However, once the smart dogs realized they were getting rewarded, the trepidation seemed to disappear. In fact, the dogs had such a good time playing the computer "game" That scientists had a hard time keeping them away from the touch screens after the study was completed.
The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctly. Since the touch-screen models were all females, this confirmed what has been observed in previous studies dogs are more efficient at reading facial expressions of people that are the same gender as their owner.
（1）How did the scientists conduct the experiment?
A.By leaving dogs to women who are either happy or angry.
B.By mixing the selected dogs together.
C.By rewarding only half of the dogs touching the screen
D.By showing digital pictures of women's happy or angry faces.
（2）The underlined word "trepidation" in Paragraph 5 probably means ________.
A.fear and hesitation
B.curiosity and eagerness
C.excitement and happiness
D.doubt and sadness
（3）According to the last paragraph, dogs with female owners ________.
A.are fond of the male faces
B.are uninterested in telling the emotions on the entire faces
C.have difficulty telling the moods on the faces of males
D.can only recognize emotions of females
（4）What is the best title for this passage?
A.Mood Changes Influence Dogs
B.Dogs Identify the Moods
C.dogs and Their Owners
D.Dog's Mood Research
【答案】（1）D
（2）A
（3）C
（4）B
【解析】【分析】本文是一篇说明文，最新的实验发现，即狗能够识别人的面部表情的变化。

（1）考查细节理解。

根据第二段中的"For their study biologist Corson Miller and his team exposed eleven selected dogs to digital images of women that were either angry or happy."可知，实验人员通过屏幕向这些狗展示了一组女性面部表情的照片，这些表情中既有快乐的，也有愤怒的。

故选D。

（2）考查词义猜测。

根据第五段中的"They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly"以及"However"可知，与前面意思相反，以及划线词后的"disappear"可知"once the smart dogs realized they were getting rewarded, the trepidation seemed to disappear.…"此句为，狗看到生气的表情后会感到厌恶，并由此退缩，但是一旦聪明的狗意识到会有奖励之后，它们的恐惧以及退缩就会消失。

由此可判断出A 符合题意，故选A。

（3）考查推理判断。

根据最后一段中的"......this confirmed what had been observed in previous studies―dogs are more efficient at reading facial expressions of people that are the same gender as their owner"可知，狗擅长辨别与自己主人性别相同的人的表情，由此推断，让主人是女性的狗来辨别男性面部表情的图片是比较困难的。

故选C。

（4）考查主旨大意。

第一段提出文章的主旨即“每个狗的主人都知道他们的狗狗能很好地读懂他们的情绪，但科学家们一直有点怀疑。

现在，有证据表明这是正确的”，接着在下文用硬实证明了这一点。

因此本文的最好的题目就是“狗能识别人的情绪”。

故选B。

【点评】本题考点涉及细节理解，词义猜测，推理判断和主旨大意四个题型的考查，是一篇科研类阅读，要求考生在捕捉细节信息的基础上，进一步根据上下文的逻辑关系，进行分析，推理，概括和归纳，从而选出正确答案。

2．犇犇阅读理解
The Alexander technique
Until earlier this year, I didn't know anything about the Alexander technique—and saw no reason to think I should. One day, the backache I regularly suffered was more painful. I was brought up to think that the preferred way of dealing with aches is to do nothing and hope they'll go away, but I eventually went to the doctor. After examining me, he said, "You actually have bad posture (姿势). Go off and learn the Alexander technique." Three months later I could walk straighter and sit better.
The Alexander technique is a way of learning how you can get rid of harmful tension in your body. The teaching focuses on the neck, head and back. It trains you to use your body less severely and carry out the movements that we do all the time with less effort. There is little effort in the lessons themselves, which sets apart the Alexander technique from yoga or pilates, which are exercise-based. A typical lesson involves standing in front of a chair and learning to sit and stand with minimum effort. You spend some time lying on a bench with your knees bent to straighten the spine (脊椎) and relax your body while the teacher moves your arms and legs to train you to move them correctly.
The technique helps to break the bad habits accumulated over years. Try folding your arms the opposite way to normal. This is an example of a habit the body has formed which can be hard to break. Many of us carry our heads too far back. The head weighs four to six kilos, so any inappropriate posture can cause problems for the body. The technique teaches you to let go of the muscles holding the head back, allowing it to go back to its natural place on the top of our spines.
So who was Alexander and how did he come up with the technique? Frederick Alexander, an Australian actor born in 1869, found in his youth that he had vocal (声音的) problems during performances. He analyzed himself and realized his posture was bad. He worked on improving it, with excellent results. He brought his technique to London and opened a teacher-training school, which is still successful today.
So if you're walking along the road one day with shoulders bent forward, feeling weighed down by your troubles, give a thought to the Alexander technique. It will help you walk tall again.
（1）What does the author suggest in Paragraph 1?
A. She felt no better after the treatment.
B. She got bored with the Alexander technique.
C. She was sceptical about the doctor's method.
D. She was unwilling to seek treatment for her backache.
（2）What is the principle of the Alexander technique?
A. Physical tension shouldn't be completely relieved.
B. The technique shouldn't be combined with other exercises.
C. The practice of the technique shouldn't be attempted alone.
D. Familiar physical actions shouldn't be done with much effort.
（3）What can we learn about Frederick Alexander?
A. He managed to recover his vocal powers.
B. He was eager to make a name for himself.
C. He developed a form of exercise for actors.
D. He had to leave home to develop his technique.
（4）What is the main idea of the passage?
A. The occurrence of back pain is widespread.
B. Alexander improved the technique to treat body pain.
C. The Alexander technique helps overcome posture problems.
D. People with back pain are victims of inappropriate postures.
【答案】（1）D

3．犇犇阅读理解
In our twenties, we find it funny when we can't remember our neighbor's cat's name or a handsome actor who starred in a famous movie. In our thirties, we jokingly call it "brain freeze". In our forties, we laugh it off as a" senior moment" and follow up with one of these old age jokes. But the reality is that there comes a point when being forgetful stops being funny and starts to seem a bit dreadful. You think, "Am I losing it？"Or worse, "Is this a sign of Alzheimer's disease （老年痴呆症）？"
Well, don't worry. The fact that you recognize your own forgetfulness may be a very good sign, at least in terms of the possibility of your developing Alzheimer's disease（AD）. The researchers in a new study show that it's not forgetfulness but not being aware that we're forgetful that we should fear.
The researchers began with the assumption that one common feature of Alzheimer's dis-ease is a damaged awareness of illness. And they wanted to prove their theory that the lack of awareness can be used to predict whether someone with" mild cognitive（认知的）damage" will progress to full-on AD. For the study, "mild cognitive damage" was defined as someone
whose mental state was considered healthy but who had either complained of memory loss or had suffered objective memory loss.
The researchers used existing data for 1, 062 people between the ages of 55 and 90 that had been recorded over a 12-year period. The data included brain scans, which the researchers used to look for visual signs of reduced glucose uptake（葡萄糖吸收）.It is an objective marker of the sort of reduced brain function that goes along with AD.As expected, glucose uptake was reduced in those with AD. What the researchers also discovered was that glucose uptake was reduced in those with mild cognitive damage who also showed evidence of reduced illness awareness. Finally, the researchers found that those who had reduced illness awareness were more likely to develop AD than those without.
（1）What can be implied from paragraph 1？
A. People can be forgetful at different ages.
B. The memory of the young is better than the old.
C. Old people are most afraid of getting Alzheimer's disease.
D. It's a rare phenomenon when young people forget something.
（2）What statement does the researchers in the new study agree with?
A. Being aware all the time is a fearful thing.
B. Illness awareness has nothing to do with Alzheimer's disease.
C. Recognizing forgetfulness doesn't mean developing Alzheimer's disease.
D. Realizing forgetfulness must be a sign of developing Alzheimer's disease.
（3）What can be a sign of developing Alzheimer's disease?
A. Realizing others' forgetfulness.
B. Reduced uptake of glucose.
C. Having higher intake of glucose.
D. Expected increase in brain function.
（4）From which is the text probably taken?
A. Science fiction.
B. A chemistry book.
C. A science research.
D. A health brochure.
【答案】（1）A
（2）C
（3）B
（4）C
【解析】【分析】本文是一篇说明文，介绍了如何预测你的记忆丧失是否是老年痴呆症, 一项新的研究表明，不是遗忘，而是没有意识到我们的健忘让人们感到害怕。

（1）考查推理判断。

根据第一段中的“ I n our twenties, we find it funny when we can't remember our neighbor's cat's name or a handsome actor who starred in a famous movie. In our thirties, we jokingly call it ‘brain freeze’In our forties, we laugh it off as a‘senior moment’ and follow up with one of these old age jokes. But the reality is that there comes a point when being forgetful stops being funny and starts to seem a bit dreadful.”在二十多岁的时候，当我们记不起邻居的猫的名字或是主演一部著名电影的英俊演员时，我们觉得很有趣。

在三十多岁的时候，我们开玩笑地称它为“大脑冻结”，在四十多岁的时候，我们把它当作“老年时期”来嘲笑，然后继续讲这些老年笑话。

但现实是，有这样的时候，健忘不再有趣，而且看起来有点可怕，可推知选A。

（2）考查细节理解。

根据第二段中的“ The fact that you recognize your own
forgetfulness may be a very good sign, at least in terms of the possibility of your developing Alzheimer's disease（AD）”承认自己的健忘也许是一个很好的迹象，至少从你患老年痴呆症,的可能性来看，可知选C。

（3）考查细节理解。

根据第四段中的“ It is an objective marker of the sort of reduced brain function that goes along with AD.As expected, glucose uptake was reduced in those with AD.”这是一个患有老年痴呆症降低了脑功能的客观标志。

正如所料，老年痴呆症患者的葡萄糖吸收降低，故选B。

（4）考查推理判断。

纵观全文可知，是一项科学研究，介绍了如何预测你的记忆丧失是否是老年痴呆症, 故选C。

4．Directions: Choose the one that fits best according to the information given in the passage you have just read.
A tiny clue found in ancient deposits has unlocked big secrets about Greenland's past and future climate. Just beyond the northwest edge of the vast Greenland Ice Sheet, researchers have discovered lake mud that have survived the last ice age. The mud, and remains of common flies in it, record two interglacial periods(间冰期)in northwest Greenland.
Although researchers have long known these two periods—the early Holocene and Last Interglacial—experienced warming in the Arctic, the mix of fly species shows that Greenland was even warmer than previously thought. "As far as we know, it has never been found in Greenland. We think this is the first time anyone has reported it in ancient deposits or modern lakes there," Axford said. "We were really surprised to see how far north it migrated (迁徙)."
This new information could help researchers better measure Greenland's sensitivity to warming, by testing and improving models of climate and ice sheet behaviour. Those models could then improve predictions of how Greenland's ice sheet might respond to man-made global warming. After all, Greenland covers 80 per cent of the Arctic country and holds enough ice to equal 20 feet of global sea level. "Northwest Greenland might feel really remote, but what happens to that ice sheet is going to matter to everyone in every coastal city around the world," said Yarrow Axford, an associate professor in the team. "One of the big uncertainties in climate science is how fast the Earth changes when it gets warmer. Geology gives us an opportunity to see what happened when the Earth was warmer than today," said Axford.
People might be surprised to see how today's Greenland looked during the last two interglacial periods. During the Last Interglacial, global sea levels increased by 15 to 30 feet, largely due to thinning of Greenland and Antarctica's ice sheets. However, now researchers believe northern Greenland's ice sheet experienced stronger warming than previously thought, which could mean that Greenland is more responsible for that sea-level rise.
Finding lake deposits older than about 10,000 years, however, has been historically very difficult in Greenland. To measure these ancient temperatures, researchers look to ice cores (冰核) and lake deposits. Since ice and lake deposits form by a gradual buildup on annual layers of snow or mud, these cores contain history of the past. By looking through the layers, researchers
can obtain climate clues from centuries ago.
（1）Why are the remains of flies mentioned in the first two paragraphs?
A.They serve as evidence that there is still life in the Northwest Greenland.
B.They were one of the many ancient lives that were left in the Greenland mud.
C.They are indicators that Greenland was much warmer than previously thought.
D.They help the researchers realize that there was once a warm period in the Arctic.
（2）The new information about Greenland is important because______________.
A.researchers have no idea how to measure Greenland's warming speed
B.it can help researchers better predict Greenland's response to warming
C.people should be more sensitive to the changes in the ice in Greenland
D.it is uncertain how fast the Earth changes with man-made global warming
（3）Which of the following can be inferred from the passage?
A.It is easier for today's scientists to find ancient lake deposits.
B.People are surprised at the landscape feature of Greenland today.
C.Researchers measure the changing temperatures by directly examining mud.
D.Greenland holds enough ice that might one day threaten life in coastal cities.
（4）Which do you think is the best title of the passage?
A.Greenland Used to Be Much Greener
B.Earth Once Experienced Warm Periods
C.Coastal Cities Warned of Coming Disasters
D.Northwest Greenland, A Perfect Destination
【答案】（1）C
（2）B
（3）D
（4）A
【解析】【分析】本文是一篇说明文，介绍了在古代沉积物中发现的一条微小线索揭开了格陵兰岛过去和未来气候的大秘密。

就在广阔的格陵兰冰原的西北边缘，研究人员发现了在最后一个冰河时代幸存下来的湖泥。

现在研究人员认为，格陵兰北部的冰盖经历了比之前认为的更强烈的变暖。

（1）考查推理判断。

根据第一段中的“The mud, and remains of common flies in it, record two interglacial periods（间冰期）in northwest Greenland.”在格陵兰岛西北部，泥浆和常见苍蝇的残骸记录了两次间冰期；以及第二段中的“Although researchers have long known these two periods—the early Holocene and Last Interglacial—experienced warming in the Arctic, the mix of fly species shows that Greenland was even warmer than previously thought. ”尽管研究人员很早就知道这两个时期——全新世早期和最后一次间冰期——在北极经历了变暖，但混合的蝇类表明格陵兰岛甚至比之前认为的还要热。

可知，在前两段中提到苍蝇的残骸是为了证明格陵兰岛的温度比之前认为的要高得多。

故选C。

（2）考查细节理解。

根据第三段中的“This new information could help researchers better measure Greenland's sensitivity to warming, by testing and improving models of climate and ice sheet behaviou r. ”可知，这些新信息可以帮助研究人员更好地测量格陵兰岛对气候变暖的敏
感性。

故选B。

（3）考查细节理解。

根据第三段中的“After all, Greenland covers 80 per cent of the Arctic country and holds enough ice to equal 20 feet of global sea level. ‘Northwest Greenland might feel really remote, but what happens to that ice sheet is going to matter to everyone in every coastal city around the world,’” 可知，格陵兰岛覆盖了这个北极国家的80%，拥有相当于全球海平面20英尺的冰。

“格陵兰西北部可能真的感觉很遥远，但冰盖的变化将关系到世界上每个沿海城市的每个人。

”故选D。

（4）考查主旨大意。

本文通过最新的发现——最后一个冰河时代幸存下来的湖泥及湖泥中的苍蝇残骸及其相关研究说明格陵兰岛之前可能更暖和。

因此，本文的最佳标题应为“格陵兰岛曾经更加绿色”。

故选A。

5．阅读理解
Darrell Blatchley, a marine biologist and environmentalist based in the Philippine city of Davao, received a call from the Philippines, Bureau of Fisheries and Aquatic Resources (渔业与水产资源局) early Friday morning reporting a death of a young whale.
When the necropsy (尸检) was performed, Blatchley told NPR, he was not prepared for the amount of plastic they found in the whale's stomach. "It was full of plastic nothing but nonstop plastic." he said "It was filled to the point that its stomach was as hard as a baseball." That means that this animal has been suffering not for days or weeks but for months or even a year or more," Blatchley added.
Blatchley is the founder and owner of the D'Bone Collector Museum, a natural history museum in Davao. In the coming days, the museum will display all the items found in the whale's system. Blatchley and his team work with the Bureau of Fisheries and Aquatic Resources and other organizations to assist in rescue and recovery of marine animals.
"Within the last 10 years, we have recovered 61 whales and dolphins just within the Davao Gulf," he said. "Of them, 57 have died due to man whether they took plastic or fishing nets or other waste, or gotten caught in pollution — and four were pregnant."
Blatchley said he hoped that the latest incident would launch the issue of plastic pollution in the Philippines and across the globe. "If we keep going this way, it will be more uncommon to see an animal die of natural causes than it is to see an animal die of plastic," he said.
（1）What can he inferred from the second paragraph?
A. The whale was starved to death.
B. Blatchley was shocked at what he found.
C. The dead whale must have swallowed a baseball.
D. Blatchley didn't make preparations for the necropsy.
（2）What will be shown in the D'Bone Collector Museum?
A. Waste collected from the ocean.
B. The whole system of the whale.
C. Things found in the whale's body.
D. Many different tools of whaling.
（3）What does Blatchley think of plastic pollution in the Philippines?
A. Uncommon.
B. Worrying.
C. Inspiring.
D. Mild.
（4）What is the best title for the text?
A. A Whale Found Dead of Plastic
B. Stand Up for Protecting Whales
C. Plastic Threatening Our Existence
D. Natural Death or Merciless Murder
【答案】（1）B
（2）C

6．阅读理解
If American waterways had ever been voted on the yearbook, the Buffalo River could easily have been named Ugliest. It could be hard to find hope there. It took decades for public perception of the river to shift. But activist citizens, who collaborated with industry, government, and environment groups never gave up on their polluted river—the Buffalo River gradually went from being considered a lost cause to a place worth fighting for. And by now the cleaned—up water is one of Buffalo'S biggest attractions.
By the 1960s, the river was seen as one of the worst sources of pollution pouring into the Great Lakes. The Buffalo River had caught fire many times. The surface had an oily layer, and any fish caught there were not eatable.
The waterway's fate started shifting in the mid-1960s. Stanley Spisiak was a local Polish—American jeweler by day, but by evening he was the kind of guy who'd chase down dumpers(垃
圾车)he spotted on the Buffalo River. By 1966 he found himself winning the National Wildlife Federation's "Water Conservationist of the Year" award. And before long he got a nickname:" Mr. Buffalo River. "But there was only so much he could do—the river was still declared biologically dead in 1969.
Jill Spisiak Jedlicka is his great-grandniece. She picks up where he left off by directing the river's protector organization, Buffalo Niagara Waterkeeper. Professor Schneekloth and seven friends founded the organization as an all-volunteer nonprofit in 1989, after organizing the first river cleanup that year. Today the group employs 27 full-time workers and has helped oversee the Buffalo River's $100 million restoration.
So far, the Buffalo River's water quality has restored, but it is still an ongoing issue, as sewage(污水)can overflow into the river after storms. Habitat restoration continues as well; fish and plantings are still being sampled to measure how well it's gone.
（1）What did the Buffalo River use to be?
A. A waterway on the yearbook.
B. A river heavily polluted.
C. A great attraction of Buffalo's.
D. A place worth fighting for.
（2）Why was Mr.Spisiak named "Mr. Buffalo River"?
A. Because his fate shifted in the 1 960s.
B. Because he spotted dumpers on the River.
C. Because he spared no efforts to protect the river.
D. Because the river was declared biologically dead.
（3）How long did it take for the river to restore?
A. More than half a century.
B. Just four decades.
C. About 30 years.
D. Only 27 years.（4）What can be a suitable title for this text?
A. The restoration of the Buffalo River
B. Stanley Spisiak: The "Mr.Buffalo River"
C. The future of the Buffalo River
D. River protection: A long way to go
【答案】（1）B
（2）C
（3）A
（4）A
【解析】【分析】本文是一篇记叙文，讲述了被污染的the Buffalo River的恢复。

7．阅读理解
Compared with solar and wind energy, which are booming, tidal (潮汐的) power is a loser in the clean - energy competition. But if you did want to build a tidal power station, there are few better sites than the mouth of the River Severn, in Britain. Its tidal range, the difference in depth between high and low tides, of around 15 metres is among the largest in the world.
Engineers and governments have been toying with the idea since at least 1925. But none of the suggested projects has materialised. Price is one objection. A study thought that tidal energy might cost between ￡216 and ￡368 ($306 - 521) per MWh of electricity by 2025, compared with ￡58 - 75 for seagoing wind turbines (轮机) and ￡55 - 76 for solar panels. Environmentalists also worry that any plant would change the tides, making life harder for wildlife.
An engineer called Rod Rainey thinks he has a way around both problems. He plans to replace the conventional turbines of previous plans with a much older technology. Specifically, he plans to span (横跨) the river mouth with a line of water wheels. This is a design that dates back to the early days of the Industrial Revolution. Examples can be found fixed to the sides of old watermills (水磨).
But there would be nothing old - fashioned about Mr Rainey's wheels. Thirty metres high and sixty wide, they would be made from ordinary steel. Two hundred and fifty of them, along with the supporting structures, would be floated into place and secured to the seabed, creating a line 15km long. Together, they could supply power at an avenge ate of 4GW. That is about as much as two biggish nuclear power stations would manage. Substituting one of the wheels with a set of locks would provide a shipping channel about twice the width of Panama Canal, permitting upstream ports such as Avonmouth and Cardiff to continue operating.。
