When fisheries biologist James Drymon noticed feathers in the vomit of a tiger shark, he first assumed they belonged to some unfortunate seabird: a gull, perhaps, or a pelican. But when he and his team genetically sequenced the feathers, the results surprised them: the feathers came from a land-based songbird called a brown thrasher. So what was it doing in a tiger shark’s stomach in the Gulf of Mexico?
Drymon, a researcher at Mississippi State University’s Coastal Research and Extension Center, and his colleagues sorted songbird from a tiger shark’s stomach through the stomach contents of 105 juvenile tiger sharks between 2010 and 2018. Nearly 40 percent had recently feasted on birds that come from dry land. In all, the scientists counted 11 terrestrial bird species showing up on the sharks’ menu. The results were published online in May in Ecology. Researchers have known since the 1960 s that sharks sometimes eat songbirds. “But what was interesting to us was the prevalence of the behavior,” Drymon says, “This is something that happens every year in a high number of sharks.”
Every fall and spring, songbirds undertake dramatic migrations across the Gulf of Mexico. If bad weather comes along, they can be forced to land on the water—which is effectively a death sentence. “The estimate for the number of migrants that die because of storm-related events is in the billions,” Drymon says. He suspects that sharks have long taken advantage of this twice-yearly nutritional bounty raining down from the skies, but scientists have only recently had the genetic tools to confirm this by identifying partially digested feathers.
“The results stressed how interconnected marine and terrestrial ecosystems can be,” says University of Miami marine ecologist Neil Hammerschlag, who was not involved in the study, “It shows how opportunistic these sharks are.”
1.How did James Drymon and his colleagues identify the feathers?
A.By making comparison. B.By checking their DNA.
C.By observing them closely. D.By analyzing previous data.
2.What do we know about tiger sharks?
A.They dislike terrible weather. B.Most of them feed on land birds.
C.They actively catch songbirds for food. D.They are good at making use of opportunities.
3.According to the passage, what do songbirds fear most when they migrate?
A.Sharks in the sea. B.Other larger birds.
C.The stormy weather. D.The long distance.
4.What is the text mainly about?
A.Tiger sharks’ eating habit. B.Researchers’ identification of feathers.
C.Land birds’ suffering a lot when migrating. D.Land birds’ being on the menu of tiger sharks.

高三英语完形填空简单题查看答案及解析
American writer A.N.DEVERS was at a rare-book fair in New York City in 2015 when she noticed a Joan Didion title selling for just $25. Then she saw the price tag of a novel by the equally famous Cormac McCarthy: about $600. “I realized we don’t value women’s work the same way we do men’s,” Devers says. “It’s depressing. But it’s also exciting, because I can do something about it.”
Three years later, after moving to London and joining the U.K.’s booming rare-book trade, Devers opened the red doors of her new bookstore, the Second Shelf. Located in a quiet courtyard off the busy streets of London’s Soho, the store almost exclusively stocks rare books by women (alongside a handful of male-authored books about women). The focus is modern fiction: Elizabeth Bowen novels, romances by Rosamunde Pilcher, poetry by Ntozake Shange.
Devers’ skill for finding overlooked jewels was polished during a childhood of Visits to yard sales in towns across the U.S., a result of her family’s following her father’s Air Force job. Some of her most sought-after recent finds were works by Miriam Tlali, the first black woman to publish a novel in South Africa. Devers hit on her 1975 debut in a charity store and quickly sourced and sold 15 more Tlali books.
In collecting these works, the Second Shelf is correcting a historical imbalance that has allowed women’s literary achievements to be eclipsed. Bookdealers have tended to be men; much of the trade’s early material was collected by “country gentlemen who ran estates and amassed libraries of books to show their wealth and intelligence,” Devers says. She argues that they’ve been like their peers in other male-led creative industries — including television, film and the news media — in that “they focus on themselves.”
That past contributes to a plain absence of women’s work among the books considered to be valuable cultural objects. In January, the Second Shelf went viral (走红) on Twitter after Devers pointed out that only nine books by women appeared in a list, produced by a trade website, of the 500 biggest sales at auction in the books-and-paper field last year. Even among more recently published works, a 2018 study found, titles by women are on average priced 45% lower than books by men.
In recent years, calls have gone out to read only books by women for a year and for universities to expand their curriculums. The observance of Women’s History Month in the U.S. has also made March a time for publishers to suggest fitting reading lists. Devers’ shop is the physical site of that movement challenging the current situation. “We’ve been taught to find value in something really narrow,” she says. “It’s time to explore something different.”
1.The first paragraph tells the readers _________.
A.why Devers named her shop the Second Shelf
B.how Devers was exposed to rare book trade
C.what motivated Devers to open the Second Shelf
D.where Devers first came across women’s literary works
2.The underlined word “eclipse” in the fourth paragraph means_________.
A.fully exposed
B.partially concealed
C.seriously treated
D.roughly explained
3.Which may explain the absence of the great literary works by women?
A.The trade used to be dominated by men.
B.Women writers’ ideas conflict with the bookdealers’.
C.Males tend to be productive in the creative industry.
D.The majority of male readers don’t read modern fiction.
4.What can be inferred from the passage?
A.In recent years, university curriculums have emphasized books by women.
B.Women’s History Month has pushed women writers to be more productive.
C.More physical bookstores like Devers’ are needed to change the situation.
D.The Second Shelf is helping turn a page for women in literature.

When you are sitting in the car, do you ever notice the drivers looking over their shoulders or side to side in the car? Well, they are doing this to check their blind spots! Blind spots take driving extremely difficult and increase the potential for car accidents.
Fourteen-year-old Alaina Gassler from Pennsylvania noticed her mother struggling with blind spots while driving their family car. So she came up with an ingenious solution that won the first place and $25,000 in the Broadcom Masters Competition.
Blind spots are the areas around the car that cannot be directly observed by the driver. There are two kinds of blind spots---on the back of the car that cannot be seen with mirrors, and blind spots at the front of the car as well.
When a driver is changing lanes, he has to look over his shoulder through the side windows to make sure that there is no vehicle in the blind spot. This invisible area is big enough to hide a car!
The other blind spot is created in the front by the A-pillar（柱子）---the material on either side on the windshield（挡风玻璃）that holds the glass and forms the frame of the car. In some cars, this pillar can be quite thick. Usually, people or cyclists can be hidden by this pillar.
Alaina's design was to get rid of the blind spot created by the front A-pillar of the car, the one that helps hold up the windshield.
She put a camera on the outside passenger side of the car which then sent the photos to a projector above the drivers' head. Then, she covered the inside of the pillar in reflective fabric onto which the image was projected. Basically, her device made the pillar "see through" and removed the blind spot on that side of the car.
Alnina's solution is very creative and could be improved by using LCD displays that will make it easier to see during day time as well.
1.What can be learned about blind spots during driving?
A.They call for careful driving. B.They make driving thrilling.
C.They are many in kinds. D.They can't be get rid of.
2.Which of the following can replace the underlined word "ingenious" in paragraph 2?
A.interesting B.creative
C.inspiring D.invisible
3.How did Alaina solve the problem?
A.By improving the A-pillar. B.By using a mirror on the outside of the A-pillar.
C.By relying on LCD displays. D.By using a camera to capture images.
4.What's the best title for the text?
A.An Introduction to Blind Spots B.A Warning About the Road Safety
C.A Teen's Creative Solution to Blind Spots D.Scientific Research on Blind Spots
