问题     Dave Walsh, web editor on board the Rainbow Warrior again this year, gave the following account of the 2004 expedition that followed the activities of seven ships as they trawled seamounts for target species of orange roughly.
    "We watched them raising tons of fish, corals—and even rocks from the ocean floor! Dozens of species of ’ unwanted’ deep sea life, snapped from habitat 1000km below us, were turfed over the side of the bottom trawlers, internal organs blown apart from the violent change in pressure. Hundreds of albatross—a bird usually considered a loner, drifting at the mercy of the winds-squabbled over the dead or dying fish. "
    Among the huge amounts of bottom dwelling marine life including fish, sea stars, squid, sea urchins and ghost sharks that were hauled up and discarded, was a delicate branch of endangered black coral, a species listed on the UN Convention on International Trade in Endangered Species(CITES)for over 20 years. Black coral is also protected in adjacent New Zealand waters. Corals are the foundation of unique deep-sea communities and their destruction affects everything else living in or near them on the sea floor.
    Speaking at a press conference on board the Rainbow Warrior in Auckland harbour to launch the current expedition, oceans campaigner Carmen Gravatt said "Bottom trawling is the most destructive fishing practice in the world. The deep sea is the largest pool of undiscovered life on Earth. Bottom trawling these unknown worlds is like blowing up Mars before we get there. "
    Recently, in collaboration with the Scottish Association for Marine Science(SAMS), we also concluded the exploration of a little-known coral reef complex off the west of Scotland. Using remotely operated vehicles(small, unmanned submarines), scientists studied and documented the reef, its cold water corals and the numerous species it is thought to host. Previous surveys of the reef conducted by SAMS found that parts of the coral formation are 3,800 years old and the base may be over 10,000 years old.
    Next week, our political advisor Karen Sack will speak at a UN meeting on Oceans. Will the Rainbow Warrior once again unearth crucial evidence so the UN can see with their own eyes that a moratorium is needed? "Each day bottom trawling continues, more deep sea life gets wiped out and the situation becomes more critical," said Gravatt. "A moratorium on bottom trawling in international waters is urgently needed to protect life in the deep sea. "
What does the "’ unwanted’ deep sea life" mean in Paragraph 2 according to the passage?
选项 A、They have no economic value.
B、They are dead before being caught.
C、They are dangerous to human beings.
D、They are the natural enemy of the deep sea fish.
答案A
解析 语义题。像乌贼、海胆、海星这些海洋生物因为没有经济价值而未成为渔民捕捞的对象，对他们来讲是不需要的东西，所以[A]是正确答案。
