A
Ears are for hearing — everyone knows that. But for a creature called the Cuvier's beaked whale, hearing starts in the throat, a new study found.
The observation might help explain how all whales hear. The work
might also help scientists understand how animals are affected
by underwater sonar (声呐)．This sonar，used by some ships，sends
out sound waves to locate underwater objects.
The Cuvier's beaked whale is a so-called toothed whale.
Toothed whales dive deep into the ocean in search of food. As the
whales hunt, they produce sounds that reach objects and then return to the whales. This allows the animals to “see” the shape, size, and location of objects, even when they're 1,000 meters under the sea, where it is totally dark.
To better understand how the whale hears, researchers from San Diego State University in California took X-rays of two Cuvier's beaked whales. The whales had died and washed up on the beach.
Ted Cranford and his colleagues used the images to make a computer model of a Cuvier's beaked whale's head. Then, they modeled the process of sound traveling through the head.
The researchers knew that some sounds get to the ears of a toothed whale through a structure called “the window for sound”. Found on the lower jaw, this structure is very thin on the outside and has a large pad (垫) of fat on the inside.
When the researchers used their computer model to work out how sound waves travel in the whale's head, they were surprised to find that sounds coming from right in front of the whale actually travel under the animal's jaw. From there, sound waves move through the throat, into a hole in the back of the jaw, and finally to the pad of fat near the animal's ears.

For years, the giant squid (大王乌贼) had remained a modern mystery. Living in the dark depths of the ocean, the creature is difficult for scientists to observe directly. It had also managed to avoid all attempts to film it. That changed last July: for the first time ever, scientists were able to catch the giant squid on video in its natural habitat. They were amazed by what they saw. The scientists filmed the squid in the North Pacific Ocean, south of Tokyo, Japan. They followed it down to a depth of 2,952 feet. They shot more than 23 minutes of video before the squid swam off into even darker depths. The video footage will be released to the public later this month on The Discovery Channel.
Tsunemi Kubodera, a zoologist at Japan's National Museum of Nature and Science, led the team that filmed the squid. The team went into the ocean in a small submarine with lights invisible to both humans and squid. Since giant squid eat smaller squid, the scientists released a small squid as bait (诱饵). Then the scientists waited in the pitch black for the giant squid to approach.
The color video shows the creature floating vertically, eating the bait squid. The giant squid is 9 to 10 feet long and is missing its two longest tentacles (触须). With those tentacles, it could have measured up to 26 feet long. It has huge black eyes, the size of dinner plates, “It was shining and so beautiful，” Kubodera said.
Because the deep ocean is so unfriendly to humans, little is known about the giant squid. Scientists say catching the mysterious creature on video is an important step toward understanding it. For centuries, sailors had reported seeing a huge, ocean-dwelling beast, thought to be the giant
squid. The creature is also believed to be the subject of the Nordic myth of the kraken, a sea creature that supposedly attacked ships in Scandinavian waters over the past thousands of years.
语篇解读：本文是一篇科普类说明文。

大王乌贼生活在深海，人们很难有机会看到它，长期以来人们对它知之甚少。

最近科学家在深海拍摄到了这种神秘的生物，有望揭开其神秘的面纱。

4．Why is it difficult to film the giant squid?
A．Because it is illegal to film the giant squid.
B．Because it is too expensive to make such a film.
C．Because the giant squid lives in the dark deep ocean.
D．Because the giant squid is dangerous to humans.
详细分析：选C细节理解题。

根据第一段中的“Living in the dark depths of the ocean, the creature is difficult for scientists to observe directly.”可知，因为大王乌贼生活在大洋深处，所以人们很难拍摄到它。

5．We can learn from the first paragraph that scientists ________.
A．first saw the giant squid in the ocean
B．discovered a new sea creature in the ocean
C．have the ocean bottom secretly recorded on video
D．have first caught the legendary giant squid on video
详细分析：选D细节理解题。

根据第一段内容可知，科学家在北太平洋下到深度为2 952英尺的地方第一次拍摄了一段23分钟长的有关大王乌贼的视频。

因此D项正确。

6．According to the passage, the giant squid's longest tentacles can be ________.
A．16 to 17 feet long B．9 to 10 feet long
C．more than 26 feet long D．about 36 feet long
详细分析：选A细节理解题。

根据第三段内容可知，这只大王乌贼有9到10英尺长，算上它的触须可达到26英尺长，由此可得出这只大王乌贼最长的触须有16到17英尺长。

7．The scientists released a small squid in the ocean to ________.
A．increase the number of the giant squid
B．trick the giant squid into coming out
C．make an educational film about it
D．show concern for the giant squid
详细分析：选B细节理解题。

A contest organised by Airbnb is offering three lucky winners the chance to spend a night in the company of sharks. The winners and their guests will get access to a transparent (透明的)
Interested applicants, who must be 18 years or older and in good health, can apply for the contest through the Airbnb website. “On the 11th, 12th, and 13th of April, the Paris Aquarium will open its doors for a night in a room full of sharks，”the website states. “And not just any room: you will sleep in a round bed, with a breathtaking view of the worl d of sharks.”
The unusual event will be hosted by a free diver, photographer, and shark enthusiast Fred Buyle, and a biologist will provide the winners with a special course on sharks —their mysterious lives and their roles in the ocean's ecosystem, with which the winners can better understand the sharks and thus avoid disturbing their life in the aquarium when they stay there.
Upon arrival, the winners will first be taken to their rooms for presentations, followed by dinner at the shark tunnel and a night stay among the sharks. A twin bed, soap, toilet paper, and shampoo are all included in the package, as well as the breakfast of the next morning. The stay is completely free, and so is the travel arrangement to and from Paris.
Applications must also include a message addressed to the judges. In 50 to 500 characters, applicants must explain why they're the perfect candidate for the event. The choices of languages include English, German, Spanish, French, Italian and Portuguese. In case of Chinese, Japanese, and Korean, the word limit is between 50 and 300. Remember that other languages are not allowed. Of course, an Airbnb account is a must for every applicant.
If selected, the winners will be forbidden from diving or swimming in the aquarium, and will be required to keep their hands and feet indoors at all times. Photographing is not allowed because sharks are sensitive to light. Besides, the organisers advise against watching movies like Ja w s before checking in.
语篇解读：本文属于广告类应用文，主要介绍了Airbnb公司组织的一场选拔比赛，三名获胜者将有机会在水下的玻璃卧室中与鲨鱼共度一晚。

根据第一段，尤其是第二句“The winners and their guests
will get access to a transparent (透明的
where 35 sharks are living.”可知，三名获胜者将有机会睡在鲨鱼环绕的房间里，故D项正确。

10．What can be inferred from the last paragraph about the winners?
A．They can dive in the aquarium.
B．They can take photos of the sharks.
C．They must stay indoors at all times.
D．They must watch movies about sharks before checking in.
