About a billion birds die from flying into buildings each year in North America. Suspicions have been that birds may regard the open areas behind glass as safe passageways. Or they may mistake the reflected trees for the real thing.

Researchers would like to reduce collisions, which requires a solid understanding about what makes a bird more or less likely to die by crashing into a building in the first place.

“There was relatively little known at a broad scale. Previous studies were at one small study site.'' Jared Elmore, a graduate student in natural resource ecology and management at Oklahoma State University. So he and his colleagues used a previously created data set of building collisions for birds at 40 sites throughout Mexico, Canada and the U.S.

The first finding was obvious: bigger buildings with more glass kill more birds. But the details were more remarkable. "We found that life history predicted collisions. Migrants(候鸟), insect-eaters and woodland-inhabiting species collided more than their counterparts(同类).”

Most migratory species travel at night, when lights near buildings can distract or disorient(使迷失方向)them. And Elmore thinks that insect-eating birds might be attracted to buildings because their insect prey(猎物)is attracted to the lights. He suspects that woodland species get tooled by the reflections of trees and bushes in the windows. The results are in the journal Conservation Biology.

By understanding which birds are more likely to collide with buildings, researchers can perhaps determine the best way to adapt buildings, or their lighting, to help prevent such accidents. And by knowing risks, along with migration timing and behavior, building managers can better predict when birds are at their greatest danger - and improve lighting strategics accordingly.

Elmore's next project will use radar to help predict bird migrations. " I think that would maybe go a long way in terms of providing information to people, to the public, to building managers, on when they can get the most benefit in terms of lights-out policies."

1. What is the possible reason for birds' crashing into buildings?
A.They didn't see the buildings.
B.They took reflections for reality.
C.They assumed the windows to be open.
D.They considered buildings as safe routes.
2. What is Jared Elmore's study different from the previous ones?
A.It created a new data set.
B.It went beyond national borders.
C.It covered a wider range of sites.
D.I’ll studied some specific bird species.
3. What was the most noticeable finding of Jared Elmore's study?
A.Migratory species travel at night.
B.Birds tend to be misled by glasses.
C.Bigger buildings cause more collisions.
D.Birds living habits give rise to collisions.
4. Which of the following can help reduce bird collision?
A.Adjust the lightening system.
B.Attach radars to each building.
C.Adopt strict lights-out policies.
D.Ban using glasses on buildings.

文章大意:这是一篇说明文。文章主要说明了保护组织正在教以前的偷猎者努力保护海龟的安全。

【推荐1】Many kinds of turtles (海龟) found in the Philippines are endangered. But now, the turtles have one less threat. Many people who used to collect their eggs to eat or to sell are now working to keep turtles safe.

Those people are called poachers (偷猎者). Now, however, protection organizations are teaching former poachers how to safely collect the eggs and protect them before they hatch (孵化). The people who do this are paid about 37 cents per egg. That is four times more than they would earn from selling them illegally.

One of the former poachers is Johnny Manlugay. “I’ve learned to love this work,” he said, adding that he did not know it was illegal to eat turtle eggs and their meat. He now collects the eggs carefully and brings them to a group called Coastal Underwater Resource Management Actions (CURMA), which takes the eggs and puts them under the sand in a safe place. When the baby turtles hatch, they are directed to the water.

The turtles are called “pawikan” in the local language. They are at risk not only from poachers, but also climate change and habitat loss.

Carlos Tamayo is one of CURMA’s leaders. “We talked to the poachers, and it turned out poaching was just another means for them to earn a living,” he said. “They had no choice.”

Cabagbag is over 40 years old. His wife and seven-year-old son sometimes help him collect turtle eggs. Since October, they have taken over 1,000 eggs to CURMA. Cabagbag said that once he received training and learned that the turtles were endangered, he stopped poaching.

When the baby turtles hatch, many visitors come to watch them run down the beach and into the water. Cabagbag said seeing the turtles get safely into the water brings him a feeling of joy.

1. What is one of the ways of the organizations to protect turtles?
A.Teaching former poachers to collect and protect turtle eggs.
B.Getting the locals to receive more education.
C.Encouraging the locals to develop tourism.
D.Helping raise the locals’ earnings.
2. What can be known about Johnny Manlugay?
A.He helps place the eggs under the sand.
B.He encouraged his family to collect the eggs.
C.He has taken more than 1,000 eggs from CURMA.
D.He once lacked the awareness of protecting turtles.
3. Which threat to turtles is not mentioned in the text?
A.Poachers.B.Climate change.C.Ocean pollution.D.Habitat loss.
4. What can be the best title for the text?
A.Turtles Are at Risk from Climate Change
B.Former Turtle Poachers Are Now Protectors
C.Turtle Population in the Philippines Is Changing
D.CURMA Is Offering Training of Turtle Protection to Farmers

文章大意:这是一篇记叙文,主要讲述了印度一名男子因一次误会而连续三年遭受乌鸦攻击的奇特经历,以及科学家对此现象的解释。

【推荐2】For the last three years, a man in India has been living a real-life daily nightmare (噩梦). Every time he walks out of his house, he gets attacked by a group of crows. The strange thing is that the birds only aimed at him.

Shiva Kewat, a daily wage laborer from Sumela village, says his troubles with crows began three years ago. One day, as he was walking on the street, he noticed a crow chick trapped in iron netting. Despite his efforts to help the small bird escape, it died in his hands. Some of the crows must have seen the scene and believed that he killed it, because they’ve been attacking him ever since. Kewat has to carry a stick with him. He just waves the stick around to drive them off.

Kewat said that he didn’t really take the crows’ attacks seriously until he was aware that he was the only target (目标) of the birds and that no one else had ever had a problem with them. And as word of his troubles with the blackbirds spread in and around the village, people started gathering at his house every day just to see if he’d get attacked. Some found it amusing, while others described the attacks as “sudden and frightening”.

Professor Ashok Kumar Munjal, who studies bird behavior at Barkatullah University in Bhopal, said that crows have a very sharp memory and tend to recollect those who have wronged them. While their idea of revenge (报仇) may not be as complex as ours, they do tend to conduct either single or group attacks against humans who hurt them.

1. What has been causing inconvenience to Kewat in the past three years?
A.He’s been suffering from crow droppings.B.He’s been having nightmares during sleep.
C.He’s been under attack from crows.D.He’s been the only victim of all bird attacks.
2. What led to Kewat’s troubles?
A.His cruel killing of a crow chick.B.The act of disrespect to crows.
C.His refusal to save a trapped crow chick.D.The misunderstanding between him and crows.
3. Kewat began to think much of crow attacks after he realized _________.
A.the crows attacked nobody but himB.he was attacked more and more frequently
C.more and more crows joined in the attacksD.people started gathering at his house every day
4. What does the underlined word “recollect” in the last paragraph mean?
A.Ignore.B.Remember.C.Imitate.D.Reject.

【推荐3】A ten-year-old sperm whale(抹香鲸)was found dead on a beach in Scotland.A necropsy(尸检)revealed that nearly 100 kilograms of plastic and other trash had formed clumps(硬块)in its digestive system.The tragedy quickly made headlines.Why would a top predator in the ocean eat gloves,rope,and plastic cups?

Conventional wisdom suggests that marine animals eat plastic because it is there and they don't know any better.It is true that plastic may smell like food to some of them.But that doesn't explain why only certain types of whales-deep-diving toothed whales,such as sperm whales and pilot whales-turn up dead on beaches with stomachs full of plastic.

It's possible,says Savoca,that plastic trash sounds like food to toothed whales.These species


hunt deep in the ocean,sometimes nearly 500 meters below the surface,where it's pitch black(漆黑)。They use echolocation(回声定位)to hunt for food,typically squid(乌贼)。

By contrast,baleen whales(须鲸),including humpbacks and blue whales,have natural filters(过滤器)for their food.Baleen,the brush-like filter-feeding system they have in place of teeth,as well as their narrow throats,keeping them from swallowing anything much larger than the krill(磷虾群)that forms the basis of their diet.That could help explain why baleen whales are not ending up with plastic filled stomachs.

Fifty years ago,there was almost no plastic in the ocean.The lifespan of a large whale can be


twice that long.In the lifetime of a single whale,we went from an ocean with no plastic to hundreds of thousands of tons of it.Plastic comes on top of other factors affecting life in the ocean-climate change,overfishing,shipping traffic,and noise pollution."it's a real shame because their lives are challenging enough even without the additional pressure we put onto them,"says Savoca.
1. What does Paragraph 2 mainly talk about?
A.That plastic smells like food to toothed whales.
B.That marine animals started to eat plastic decades ago.
C.That a number of toothed whales are found dead on beaches every year.
D.That conventional wisdom about why marine animals eat plastic doesn't apply to all whales.
2. Which of the following statements DOESN'T explain why toothed whales are more easily harmed by plastic pollution than baleen whales?
A.They don't feed on krill.
B.They live in the dark depths of the ocean.
C.They are not born with brush-like filter-feeding systems.
D.They don't determine the location of their food with their eyes.
3. What does the author want to emphasize in the last paragraph?
A.Whales have a longer lifespan than humans.
B.Plastic has a negative effect on climate change.
C.Great changes have taken place in the ocean in the past 50 years.
D.Plastic pollution has worsened already serious issues affecting marine life.
4. Which of the following would be the best title for the text?
A.Different diets,different fates
B.Silent killers in the ocean
C.Plastic trash in-the ocean
D.Saving whales
