The world's first-known nursery for baby giant manta rays(蝠鲼) has been discovered hidden away in the Gulf of Mexico, the place of 70 miles off the coast of Texas, after studying decades of giant manta ray data from the area by the scientists.
Where the baby manta rays grow up has long troubled scientists, as they are rarely spotted in the four to five years it takes them to become adults, when they can often grow to more than 20ft wide.
In the study Mr Stewart and colleagues describe a reef (暗礁)---filled with mantas of all ages---where the sea floor runs down into deeper water. He said "We think they may be feeding on specific types of zooplankton(浮游生物) there, then migrating up toward the surface, where we saw them. They might be hanging around the banks because it could be a little safer than open water. We’ve seen them so rarely that we know very little about these baby manta rays. We don‘t know how far they move, or exactly what they feed on, or all of the habitats these access.”
Giant manta rays are listed as species dying out by protectors, although actual population numbers of the mysterious "gentle giant" are hard to calculate. Sightings of the closely-related reef manta, however, have dropped by 90 percent in regions of southeast Asia in the past decade, according to a study.
Fishing is considered the biggest threat to giant manta numbers, both intentional and accidental. Their gill plates(腮下肉)- the parts through which they filter(过滤) their food from seawater-are sold in China for medical purposes, while they often end up as something caught by mistake due to their huge wings.
1.Where do the baby manta rays probably grow up according to the study?
A. In the deep water area.
B. On the surface of the sea water.
C. Around the banks of channel.
D. In the reef of the Gulf of Mexico.
2.What can we learn from Paragraph3?
A. Manta rays can be seen on the sea surface.
B. Manta rays prefer the open water to the banks.
C. The scientists have known much about manta rays.
D. Manta rays are fond of eating on the sea surface.
3.What is the main reason for the decrease of giant manta rays?
A. The habitat environment becomes worse.
B. They are overfished by people
C. They are not very difficult to catch.
D. People can see the reef manta much less than before.
4.What does the author intend to do in the last paragraph?
A. Summarize the previous paragraphs.
B. Warn people of their wrong behaviors.
C. Introduce some knowledge of the fish.
D. Give examples to support his point.

CALCUTTA, India Mar 24, 2006 (AP) — One of the world’s oldest creatures, a giant tortoise believed to have been about 250 years old, has died in the Calcutta zoo where it spent more than half its long life.
Addwaita, which means “the one and only” in the local Bengali language, was one of four Aldabra tortoises brought to India by British sailors in the 18th century. Zoo officials say he was a gift for Lord Robert Clive of the East India Company, who was instrumental in establishing British colonial rule in India, before he returned to England in 1767. Long after the other three tortoises died, Addwaita continued to thrive, living in Clive’s garden before being moved to the zoo in 1875.
“According to records in the zoo, the age of the giant tortoise, Addwaita, who died on Wednesday, would be about 250 years,” said zoo director Subir Chowdhury. That would have made him much older than the world’s oldest documented living animal: Harriet, a 176-year-old Galapagos tortoise who lives at the Australia Zoo north of Brisbane, according to the zoo’s Web site. She was taken from the island of Isla Santa Cruz by Charles Darwin in the 19th century.
Aldabra tortoises come from the Aldabra atoll in the Seychelle islands in the Indian Ocean, and often live to more than 100 years of age. Males can weigh up to 550 pounds. Addwaita, the zoo’s biggest attraction, had been unwell for the last few days, said local Forest Minister Jogesh Burman.
“We were keeping a watch on him. When the zoo keepers went to his enclosure on Wednesday they found him dead,” Burman said.
1. According to the passage, Addwaita ________.
A. was sent to India as a gift by British government
B. was sent to India by British sailors in 1767
C. lived together with three other Aldabra tortoises in India
D. belonged to Lord Robert Clive for some time
2. By now, the oldest animal in the world is about at ________.
A. 176 years old B. 100 years old C. 250 years old D. 200 years old
3. In the last few days before Addwaita died, he ________.
A. had been sent to hospital for treatment
B. had been playing with travelers
C. had been found not better than before
D. had stayed in his enclosure for days
4. What would be the best title for the passage?
A. An Old Aldabra Tortoise Died in India
B. A Remarkable Life: Tortoise Dies at 250
C. A Special Kind of Tortoise — Addwaita
D. The Oldest Animal Aldabra Tortoise Died

高二英语单项填空中等难度题查看答案及解析
An abandoned girl named Sophie happens to see the big friendly giant (巨人) (BFG for short), who is running through the streets of London and “blowing dreams” to children late at night. The BFG is scared that the girl will give away his secret, so he takes Sophie back to his native Giant Country. In fact, the BFG is a kind-hearted vegetarian, but other giants in his native country like nothing more than eating humans. Sophie and the BFG try to stop these giants from continuing to eat humans. During this period, they become good friends.
Spielberg’s The BFG tells the tale of an unlikely friendship brought to life in an imaginary world. However, many people say the story is a bit too kid-friendly. Optimism is Spielberg’s typical tone, but the final victorious battle against the bad guys seems a little bit too easy. And when the BFG fights for the first time against the giants who have been hurting him, it seems confusing how he successfully drives away bad guys who are almost twice his size.
Spielberg does leave a little for adult viewers to digest. The BFG doesn’t want to be seen as a monster by humans,but in the end his own kind ends up caught and locked up in isolation. Will he also be destined (注定) to spend the rest of his days in a remote place alone?
Despite being made for a younger audience, the film is still worth a watch. It doesn’t have gun-fights, death, explosions and the stuff that people seem to be interested in nowadays. But the film takes us back to a more innocent time.
1.Why is Sophie taken to Giant Country?
A. Because she leaks BFG’s secret.
B. Because she happens to see BFG running on the streets.
C. Because she lives a miserable life as an abandoned child.
D. Because she is thought to be likely to tell BFG’s secret to others.
2.What does the underlined phrase ^drives away” in Paragraph 2 mean?
A. Sends away. B. Breaks away from.
C. Frightens away. D. Keeps away from.
3.What can be inferred from the text?
A. The BFG likes nothing but eating humans.
B. Not every viewer thinks highly of this film.
C. The other giants end up captured and isolated in the film.
D. This film mainly tells the practical friendship between Sophie and the BFG
4.What type of writing is the text?
A. A movie review.
B. An advertisement.
C. An announcement.
D. A fiction.
