题目列表(包括答案和解析)
Japanese scientists have taken the first photographs of one of the most mysterious creatures in the deep ocean — the giant squid①.
Until now the only information about the behavior of the creatures which measure up to 18 meters (59 feet) in length has been based on dead or dying squid washed up on shore or captured② in commercial fishing nets.
But Tsunemi Kubodera, of the National Science Museum, and Kyoichi Mori of the Ogasawara Whale Watching Association, both in Tokyo have captured the first images of Architeuthis attacking bait③ 900 meters below the surface in the cold, dark waters of the North Pacific. “We show the first wild images of a giant squid in its natural environment,” they said in a report in the journal Proceedings B of the Royal Society.
Little is known about the creatures because it has been so difficult to locate and study them alive. Large ships and specialist equipment, which is costly, are needed to study deep sea environments.
The Japanese scientists found the squid by following sperm whales, the most effective hunters of giant squid, as they gathered to feed between September and December in the deep waters off the coast of the Ogasawara Islands in the North Pacific. They used a remote long-line camera and depth logging system to capture the giant squid in the ocean depths.
The most dramatic character of giant squids is the pair of extremely long tentacles④, distinct from the eight shorter arms. The long tentacles make up to two-thirds of the length of the dead specimens⑤ to date. The giant squid appear to be a much more active meat-eating animals than researchers had thought.
Notes:
① squid n. 鱿鱼
② capture vt. 捕获
bait n. 鱼饵
tentacle n. 触角,触须
specimen n. 标本,样本

A. Scientists captured a giant squid alive

阅读下面短文, 掌握其大意, 然后从1-25各题所给的四个选项中, 选出一 个最佳答案。
A photographer is a person who takes photos as a business or an art. It is often thought that his work is not only full of 1 but is very safe as well, and no one can imagine how 2 his work 3 .
Two photographers were 4 through a thick forest in Alaska, 5 at capturing (capture 抢拍) the wild-life on film. As there was nothing interesting to take pictures of, they were feeling 6 when they 7 sightof a brown bear that had caught a large fish by a quiet brook. The wild beast found them too, and stood on its 8 legs to get 9 sight of the two men. While doing this, the bear made a wonderful pose (n. 姿势) for the two 10 photographers.
Suddenly the bear 11 at them, while the two men kept right on taking photos of the 12 beast.

While all this was going on, the man in the tree was 20 pictures of the 21 scenes. After a while, the bear went away 22, because bears 23 dead men.
When all was safe, the photographer in the tree came down and said to his friend, "The same story 24 was told in Aesep's Fables (伊索寓言) has just happened to us, and I 25 no chances to take the photos of the wonderful scenes!"

Squirrels often communicate with whistles, chirps and chucks, which sound like the word “chuck”. Whistles and chirps are like the sounds that many birds make.Now scientists have translated some of their squirrel-speak.
Hare, a professor of zoology at the University of Maniloha in Winnipeg, and his team managed to record squirrels' alarm calls.The researchers studied the sounds and then played them back to 60 wild squirrels, which the scientists approached individually with a video recorder to capture(抓拍)their reponses.Some squirrels lifted their heads up and became.Alert(警惕的).Creatures that were more frightened simply ran for their lives and dived into caves.
"In effect then, whistles that mix with chucks say 'there's an enemy of average threat that's here', and whistles without chucks say 'there's an enemy of seemingly average threat around here somewhere', while pure chirps say, 'I'm hiding here because there's an immediate danger.' " Hare told.Discovery News.
Hare and some other researchers believe such sounds arc part of an advanced language that develops just as all other communication systems.
Although squirrels risk their lives when they call out to warn others of threats, other squirrels might admire this behaviour, thus increasingly the caller’s social status, like humans who look up to heroes. Hare added that other animals, such as birds, probably understand at least some squirrel language, since they also may benefit from the alarm calls.
In fact, another Canadian study found that deep-voiced, black-capped chickadees have their own language too.According to certain research, there are a lot of tidings in chickadees' calls, such as directing fellows' activities, keeping in contact between mates, and raising alarms.
While chickadees and other birds are often welcomed into gardens by homeowners, squirrels are frequently viewed as pests(害兽). Hare wishes a greater understanding of the complex social lives and communication systems of squirrels will provide “hope that humans will gain a greater appreciation and stop doing harm to these animals”.

Scientists have created a “ human-like robot” that can dance and do the housework.
“ Mahru” has been developed to imitate humans and can move its lips, eyebrows and pupils(瞳孔). The machine can also move its upper and lower body freely and automatically stop itself when walking.
In addition, it has been programmed to give out two kinds of pleasant smells to match its emotions.
The 1.5 tall robot was produced by researchers at the Korea Institute of Science and Technology (KIST) and is the first South Korean- developed machine of its kind.
“‘Mahru’ will open the way for the commercial use of humanoid robots doing housework,” You Bum-Jae, leader of the development research team ,said. “‘Mahru’ can dance while walking on its legs and is able to work in place of a human.”
Through an advanced motion capture (捕获) system, “Mahru” can follow a variety of human movements and move its hands freely enough to deal with any obstacles that may get in its way when walking.
State-funded KIST showed the robot during a presentation at its head office in Seoul.
People here were treated to an entertaining demonstration which saw the robot show off the full range of its skills, most notably s series of dance moves.
The research team added that they had designed another “ Mahru”, this time with sensors(传感器) allowing it to distinguish(分辨) between faces and objects.
The showing of “ Mahru” came a week after researcher in Japan said they had created the “most human-like” robot in the world. A team at robotics department of Osaka University in Japan claimed that “ robogirl”, Repliee R-1, “ looks, moves and interacts (相互作用) like a human, and has silicone(硅胶) skin that feels almost human to the touch.”
【小题1】 “Mahru” made by KIST can do the following things EXCEPT____________
A.dance with other human –like robots | B.move its body freely |
C.stop automatically when walking | D.express certain feelings through smells |
A.help robots with doing housework | B.show its scientific power |
C.make Mahru offer more fun | D.explore Mahru’s commercial use |
A.go around it | B.turn back quickly |
C.deal with it using its hands | D.ask humans for help |
A.is another Mahru | B.was made by KIST |
C.has skin feeling similar to humans’ | D.looks like a boy |
A.news report | B.research report | C.healthy report | D.entertainment report |
