活页作业(七)
Ⅰ.阅读理解
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.
1．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.
解析：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。
答案：C
2．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
解析：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录像。因此D项正确。
答案：D
3．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
解析：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。
答案：A
4．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
解析：细节理解题。根据第二段中的“Since giant squid eat smaller squid，the scientists released a small squid as bait.”可知，科学家在大洋里放一条小乌贼的目的是将大王乌贼引诱出来。
答案：B Ⅱ.七选五
