According to a recent study, a new genetically modified rice can prevent infections of HIV, the virus responsible for the disease AIDS.
The study reports the newly-developed rice produces proteins that attach directly to the HIV virus. This process prevents the virus from mixing with human cells. The scientists say it can remove the effect of the virus and block its spreading.
The Joint United Nations Program on HIV/AIDS reports that worldwide, nearly 37 million people were living with HIV in 2017. The organization says the largest number of those are in developing countries. Nearly two-thirds of HIV cases are in Africa. Now there is no cure for HIV/AIDS though there have been developments in oral drug treatments to slow the progression of the disease.
The new study predicts the rice-based method will lead to long-term use of the anti-HIV treatment across the developing world. Researchers said the "groundbreaking" discovery is "realistically the only way" that anti-HIV combination treatments can be produced at a cost low enough for the developing world.
They say the easiest and most cost-effective way to use the rice will be to make it into a cream to be put on the skin. The HIV-fighting proteins can then enter the body through the skin. People all over the world could grow the rice and make the cream themselves. This would prevent the cost and travel required for many patients to receive treatments and medicine.
The process of changing the genetic structure of food crops has been debated for some time. Critics of genetically engineered crops believe they can harm people. The scientific team says further testing is needed to ensure that the genetic engineering process does not produce any additional chemicals that could be dangerous to people.

2．犇犇阅读理解
"Acting is the least mysterious of all crafts," Marion Brando once said. But for scientists, working out what is going on in an actor's head has always been something of a puzzle.
Now, researchers have said actors show different patterns of brain activity depending on whether they are in character or not.
Dr Steven Brown, from McMaster University in Canada, said, "It looks like when you are acting, you are suppressing (压制) yourself; almost like the character is possessing you."
Brown and colleagues report how 15 actors, mainly theatre students, were trained to take on a Shakespeare role — either Romeo or Juliet — in a theatre workshop. They were then invited into
the laboratory, where their brains were scanned in a series of experiments.
Once inside the MRI scanner, the actors were asked to answer a number of questions, such as: would they go to the party? And would they tell their parents that they had fallen in love?
Each actor was asked to respond to different questions, based on two different premises (前提). In one, they were asked for their own perspective, while in the other, they were asked to respond as though they were either Romeo or Juliet.
The results revealed that the brain activity differed depending on the situation being tested. The team found that when the actors were in character, they use some third-person knowledge or inferences about their character.
The team said they also found additional reduction in activity in two regions of the prefrontal cortex (前额皮质) linked to the sense of self, compared with when the actors were responding as themselves.
However, Philip Davis, a professor at the University of Liverpool, was unimpressed by the research, saying acting is about far more than "pretending" to be someone —it involves embodying (体现) the text and language.
（1）How did Dr Brown's team conduct their research?
A. By scanning the brain activity of some actors.
B. By doing a survey with some theatre goers.
C. By interviewing some theatre teachers.
D. By consulting some experienced researchers.
（2）What is the finding of Dr Brown's research?
A. Acting is not as mysterious as people think.
B. Actors' brain activity differs when they are acting.
C. Acting is far more than pretending to be the character.
D. Actors' brain activity is more active when they are in character.
（3）How did Philip Davis react to the research?
A. He supported it.
B. He doubted it.
C. He explained it.
D. He advocated it.（4）What is the text mainly about?
A. A debate of how the brain functions.
B. A play written by Shakespeare.
C. A research on the brain activity of actors.
D. A report of the cooperation of scientists and actors.
【答案】（1）A
（2）B
（3）B
（4）C
【解析】【分析】本文是一篇说明文，介绍了一项对于演员大脑活动的研究。

现在，研究人员表示，演员的大脑活动模式不同，取决于他们是否扮演角色。

（1）考查推理判断。

根据第五段中的“Once inside the MRI scanner, the actors were asked to answer a number of questions, such as: would they go to the party?”一旦进入核磁共振扫描仪，演员们被要求回答一系列问题，比如:他们会去参加派对吗?由此推断出Brown博士的
团队是通过扫描一些演员的大脑活动进行他们的研究的，故选A。

（2）考查细节理解。

根据倒数第三段中的“The results revealed that the brain activity differed depending on the situation being tested. The team found that when the actors were in character, they use some third-person knowledge or inferences about their character.”结果显示，大脑活动的不同取决于所测试的情境。

研究小组发现，当演员在扮演角色时，他们会使用一些第三人称知识或对角色的推断。

由此可知Brown博士的研究发现，演员在表演时大脑活动是不同的，故选B。

（3）考查推理判断。

根据最后一段中的“However, Philip Davis, a professor at the University of Liverpool, was unimpressed by the research, saying acting is about far more than ‘pretending’ to be someone — it involves embodying (体现) the text and language.”然而，利物浦大学教授Philip Davis对这项研究并不以为然。

他说，表演不仅仅是" 假装" 成某个人，它还包括文本和语言的体现。

由此推断出Philip Davis对这项研究持怀疑态度，故选B。

（4）考查主旨大意。

第二段中的“Now, researchers have said actors show different patterns of brain activity depending on whether they are in character or not.”现在，研究人员表示，演员的大脑活动模式不同，取决于他们是否扮演角色，是全文的主题句，结合全文内容，可知这篇文章主要介绍了一项对于演员大脑活动的研究，故选C。

【点评】本题考点涉及细节理解，推理判断和主旨大意三个题型的考查，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。

3．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 co uld help researchers better measure Greenland's sensitivity to warming, by testing and improving models of climate and ice sheet behaviour. ”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 co untry 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。

4．阅读理解
It has been discovered that after the age of sixteen, the number of our brain cells begins to decrease at a speed of several million a year. They simply die off. In certain types of activity, the human brain is at its highest point in the early twenties, when it has collected enough information to be able to use the vast number of cells freely in the most effective way. Pure mathematics is one of the fields in which this happens, and we know that Albert Einstein made all his world-shaking discoveries between the age of about 20 and 25, and spent the rest of his life tidying them up and arranging them.
But in certain other types of activity (of which being an author is perhaps one), experience is more important than sharpness of brain, and there one usually finds that a person reaches his or her peak much later in life.
Besides sharpness of brain and experience, here is another thing that is very important, and that is wisdom. One can have a very quick, inventive brain and plenty of experience, but if one uses these foolishly, one harms both oneself and others. Wisdom does not always come with age ——there are plenty of foolish middle-aged people about ——but the average person tends to learn wisdom as he gets older, usually by making painful of embarrassing mistakes. Leaning to be wise is basically learning what is not possible; and what is possible but so difficult that it is not worth all the trouble one has to go through to get there. Mostly, it is learning about human
nature; how real people behave and react, as against how one would like them to behave and react. One can read and hear lot of idealistic stuff about how to make the world a better place, which would be found if it was based on an accurate observation of human nature, but which is basically a waste of time because it is not.
（1）According to the writer, the great discoveries made by Albert Einstein were mainly a result in________.
A.years of hard work
B.sharpness of the brain
C.rich experience
D.his deep understanding of the nature
（2）Some people achieve success much later in life because .
A.their work often requires much experience
B.they do not have a chance to show their talents
C.they have to learn lessons from failures
D.they fail to realize earlier the importance of hard work
（3）The importance of wisdom lies in the fact that .
A.it helps to avoid various mistakes
B.it contributes to one's creativity
C.it encourages one to go forward in face of difficulty
D.it provides the right direction of efforts
（4）The writer came to believe that .
A.it is always a waste of time to make plans about the future
B.it is human nature to make attempts on what looks impossible
C.one should always challenge the impossible to push the society forward
D.one has to use wisdom in deciding what is the best thing to do

【解析】【分析】本文是一篇说明文，介绍了人类的大脑在20岁左右于巅峰，在以后的成就多数是因为需要丰富的经验。

除了头脑敏锐和经验丰富外，智慧也非常重要，因为智慧为人们提供了正确的努力方向。

人们要用智慧来决定做什么才是最好的。

（1）考查推理判断。

根据第一段“It has been discovered that after the age of sixte en, the number of our brain cells begins to decrease at a speed of several million a year. They simply die off. In certain types of activity, the human brain is at its highest point in the early twenties, ... and we know that Albert Einstein made all his world-shaking discoveries between the age of about 20 and 25, and spent the rest of his life tidying them up and arranging them.” 人们发现，16岁以后，我们的脑细胞数量开始以每年几百万的速度减少。

在某些类型的活动中，人类的大脑在20岁早期处于巅峰状态,... 我们知道阿尔伯特·爱因斯坦在20到25岁之间做出了所有震惊世界的发现。

用余生来整理和安排这些发现。

根据对爱因斯坦所的发现可知，他的伟大的发现是在20-25岁之间，更是印证了人类大脑在20年代初达到了巅峰，可推断出，本段
主要研究人类大脑巅峰期，故选B。

（2）考查推理判断。

根据第二段“But in certain other types of activity (of which being an author is perhaps one), experience is more important than sharpness of brain, and there one usually finds that a pers on reaches his or her peak much later in life.”但在某些其他类型的活动中(作家可能是其中一种)，经验比头脑的敏捷更重要，人们通常会发现一个人在他一生的晚期才达到顶峰。

可推断出有些人在晚年取得成功是因为他们的工作中往往需要很多经验。

故选A。

（3）考查推理判断。

根据第三段中的“Besides sharpness of brain and experience, here is another thing that is very important, and that is wisdom.... Leaning to be wise is basically learning what is not possible； and what is possible but so difficult that it is not worth all the trouble one has to go through to get there. Mostly, it is learning about human nature；how real people behave and react, as against how one would like them to behave and react.”除了敏锐的头脑和丰富的经验外，还有一件事是非常重要的，那就是智慧。

学习成为智者，要基本的了解什么是不可能的；学习有可能但又很困难的东西，以至于不值得一个人为了达到目的而付出所有的努力。

最重要的是了解人性，了解真实的人是如何行为和反应的，以及人们希望他们如何行为和反应的。

由此可推断出智慧的重要性在于智慧能让人知道什么可做，什么不能做，即为人提供正确的努力方向。

故选D。

（4）考查推理判断。

根据最后一段中的“Leaning to be wise is basically learning what is not possible；and what is possible but so difficult that it is not worth all the trouble one has to go through to get there.

One can read and hear lot of idealistic stuff about how to make the world a better place, which would be found if it was based on an accurate observation of human nature,”成为智者，要大体上知道什么是不可能的。

学习有可能但又如此困难的东西，以至于不值得一个人为了达到目的而付出所有的努力。

最重要的是学习人性，了解真实的人是如何行为和反应的，以及人们希望他们如何行为和反应的。

人们可以读到和听到很多关于如何使世界变得更美好的理想主义的东西.......由此可推断出聪明的人必须运用智慧来决定最好要做什么事。

故选D。

5．阅读理解
Imagine your clothing could release enough heat to keep you warm and cozy, allowing you to stay comfortable in a cooler room. Or, picture a car windshield that stores the sun's energy and then releases it as heat to make the ice on the windshield disappear.
According to a team of researchers at MIT, both cases may be possible before long, thanks to a new material that can store solar energy during the day and release it later as heat. This transparent polymer film could be applied to many different surfaces, such as window glass or clothing.
Solar energy is only available about half the time we need it — during daylight. For the sun to become a major power provider for human needs, there has to be an efficient way to save it up
for use during nighttime and stormy days. Most such efforts have focused on storing and recovering solar energy in the form of electricity, but the new finding, by MlI professor Jeffrey Grossman, Postdoc David Zhitomirsky and graduate student Eugene Cho, could provide a highly efficient method for storing the sun's energy through a chemical reaction and releasing it later as heat.
The key to enabling long-term, stable storage of solar heat, the team said, is to store it in the form of a chemical change rather than storing the heat itself. But heat will disappear over time no matter how good the material around it is, so the team set up a chemical storage system that can keep the energy in a stable molecular configuration. When exposed to sunlight, the molecules can stay that way for long periods Then, when triggered (触发)by a very specific temperature or something else, the molecules return to their original shape , giving off heat in the process.
Such chemically-based storage materials, known as Solar Thermal Fuels(STF), have been developed before. But those earlier efforts were designed to be used in liquid solutions and not able to make durable (耐用的) solid-state films. The new approach is the first based on a solid-state material, in this case a polymer, and the first based on inexpensive materials and widespread production technology.
（1）What is the main purpose of Paragraph 1?
A.To show the main idea of the passage.
B.To practice readers' imagination.
C.To interest readers in the passage.
D.To introduce a new kind of material.
（2）According to the passage, what can the polymer film do?
A.It can be made into window glass.
B.It can make necessary electricity.
C.It can store energy and release sunshine.
D.It can absorb sunshine and give off heat.
（3）According to the passage, what is STF based on?
A.The chemical reaction.
B.The movement of heat.
C.The form of electricity.
D.The physical reaction.
（4）What is the advantage of the molecular configuration?
A.It is less expensive.
B.It is very powerful.
C.It is easily available.
D.It is less changeable.

根据第一段“Imagine your clothing could release enough heat to keep you warm and cozy, allowing you to stay comfortable in a cooler room. Or, picture a car windshield that stores the sun's energy and then releases it as heat to make the ice on the windshield disappear. ”想象一下你的衣服可以释放足够的热量让你温暖和舒适，让你可以在冰冷的房间里保持舒适。

或者，再想象一下车的挡风玻璃可以储存太阳的能量，然后释放热量使挡风玻璃上的冰消失)可推测，本段以衣服和骑车挡风玻璃为例，提到了如果衣服能够吸热和放热、汽车的挡风玻璃能够吸热和自动除冰那该是多么好的事，以此来吸引对着对本文的兴趣。

故选C。

（2）考查细节理解。

根据第二段中的“thanks to a new material that can store solar energy during the day and release it later as heat. This transparent polymer film could be applied to many different surfaces, such as window glass or clothing. ”多亏了这种能在白天吸热之后以热能形式释放的新型材料，这个透明的聚合物膜可以应用于许多不同的表面，如窗户玻璃或服装)可知，这种聚合物膜可以吸热，此后再以热能的形式释放出来。

故选D。

（3）考查细节理解。

根据最后一段中的“Such chemically-based storage materials, known as Solar Thermal Fuels(STF), have been developed before. ”这种以化学反应为基础的储存材料，即太阳能热燃料(STF)，以前就已经被开发出来了，可知，STF是以化学反应为基础。

故选A。

（4）考查推理判断。

根据第四段中的“But heat will disappear over time no matter how good the material around it is, so the team set up a chemical storage system that can keep the energy in a stable molecular configuration. ”但是热量会随着时间的推移而消失，不管周围的物质有多好，所以研究小组建立了一个化学储存系统，可以将能量保持在一个稳定的分子结构中)可推断，这种分子结构的优势是相对稳定。

故选D。

6．阅读理解
Some people sit outside for hours without getting bitten by mosquitoes, but it always seems like you're being eaten alive within minutes of stepping outdoors.
If this is you, you're not alone. According to Smithsonian Magazine, around 20 percent of people in the world are especially tasty to mosquitoes. What about these people makes mosquitoes' mouths water?
A popular myth claims that mosquitoes prefer certain blood types, but the fact is that they simply can't tell what your blood type is from a faraway place. Jonathon Day, a professor of medical entomology (昆虫学) at the University of Florida in the US, told NBC it's not complicated. "The two most important reasons a mosquito is attracted to you have to do with sight and smell." Mosquitoes are especially active in the late afternoon. While flying along, they use their sense of smell to find possible targets. They find victims (攻击对象) by smelling the carbon dioxide (CO2) breathed out by humans and animals. That's why you commonly find them in crowded streets and parks.
Joop van Loon, an entomologist at Wageningen University in the Netherlands, told Live Science, "Mosquitoes start orienting (使......朝向) themselves to carbon dioxide and keep flying upwind as they sense higher concentrations (浓度)."
As a result, people who simply exhale (呼出) more of the gas over time –generally, larger people – have been shown to attract more mosquitoes than others. "This is why kids don't get bitten as much ... as adults," US professor Ted Rosen told Science Alert.
This love for CO2 can also put pregnant women at increased risk for mosquito bites, as they tend to exhale 21 percent more CO2 than people of the same age and size who aren't pregnant.
In addition to carbon dioxide, the color of the clothes you wear also plays a role in attracting mosquitoes.
According to Live Science, mosquitoes can lock onto targets from up to 50 meters away. At this distance, what we wear has a huge effect. Due to their vision (视觉), people wearing dark colors are more likely to become targets.
Being bitten by mosquitoes is annoying, but don't worry. Some simple tips can help ward them off. Scientists recommend that we use insect repellent (驱虫剂) and wear light-colored clothing.（1）How do mosquitoes locate their targets, according to the article?
A.By seeking out bright clothes.
B.By identifying different blood types.
C.By sensing an increase of carbon dioxide.
D.By following bigger crowds.
（2）Why are pregnant women more likely to be bitten by mosquitoes?
A.Their larger size helps mosquitoes to see them.
B.They breathe out more CO2.
C.They are more likely to sweat.
D.Their body temperatures are higher.
（3）How does the article advise you to avoid mosquitoes?
A.Exercise regularly.
B.Wear light-colored clothing.
C.Keep your skin dry and clean.
D.Stay indoors in the evening.
（4）What's the article mainly about?
A.A new finding about mosquitoes.
B.How people can avoid mosquito bites.
C.A popular myth about mosquitoes.
D.Why some people are more attractive to mosquitoes than others.
【答案】（1）C
（2）B
（3）B
（4）D
【解析】【分析】本文是一篇说明文，介绍了为什么有些人可以整个夏天坐在户外乘凉却不被蚊子叮咬，而有些人一出门就好像要被蚊子吃掉一样。

（1）考查细节理解。

根据第四段中的“While flying along, they use their sense of smell to find possible targets. They find victims by smelling the carbon dioxide (CO2) breathed out by humans and animals. ”飞的时候，它们用嗅觉发现目标。

它们通过闻人和动物呼出的二氧化碳来锁定目标；以及第五段中的“Mosquitoes start orienting themselves to carbon dioxide and keep flying upwind as they sense higher concentrations”蚊子开始飞向有二氧化碳的地方，当它们感知到高浓度的二氧化碳时，就保持逆流飞行，可知，蚊子通过感知二氧化碳的增加来锁定目标。

故选C。

（2）考查细节理解。

根据第七段“This love for CO2 can also put pregnant women at increased risk for mosquito bites, as they tend to exhale 21 percent more CO2 than people of the same age and size who aren't pregnant.”对二氧化碳的喜欢使得孕妇很容易被蚊子咬，因为她们比正常相同年龄，相同体型的人呼出多余21%的二氧化碳，可知，孕妇呼出更多的二氧化碳，所以更招蚊子咬。

故选B。

（3）考查细节理解。

根据最后一段中的“Scientists recommend that we use insect repellent and wear light-colored clothing.”科学家建议我们使用驱虫剂或者穿浅颜色的衣服。

可知，文章建议我们可以通过穿浅色衣服来避免蚊子叮咬。

故选B。

（4）考查主旨大意。

根据第二段中的“According to Smithsonian Magazine, around 20 percent of people in the world are especially tasty to mosquitoes. What about these people makes mosquitoes' mouths water?”根据Smithsonian杂志，世界上大约20%的人容易招蚊子咬。

为什么这些人非常吸引蚊子呢？可知，本文探讨的话题是：为什么一些人比其他人更容易招蚊子。

Some years ago, Michel-Andre found himself staring at the body of a dead whale on a beach in the Canary Islands. It was obvious that the animal had been struck violently by a ship——but why? Only later, after surveying the whales which lived in the area and measuring the increase of sound pollution from ships did it become clear that there was a link.
The whales had become desensitised to the noise of approaching boats and were being struck by them, often seriously. "We never thought that this could be something that could kill," recalls (回忆) Andre, who is the director of the Laboratory of Applied Bioacoustics at the Technical University of Catalonia, Barcelona.
Andre has spent 20 years developing an advanced system to better understand why incidents like this happen. His underwater microphones have exposed a world of deafening sound and animal communication never observed with such clarity(清晰) before.
It was not an easy task. Sound waves don't travel through water in the uniform, predictable way they do through the air. Instead, the temperature, salinity (盐度) and, flow of water have great effects on their path.
What can be done? One solution is to change shipping routes to courses where ships are statistically less likely to meet animals. It's also possible to slow ships down to 18km/h or less,。
