A
The amount of fish caught worldwide is much larger than has been reported. And that could mean serious problems for the environment and nations that depend on fisheries (渔业). A new estimate shows that it is 32 million tons higher than countries have been reporting yearly.
The same report notes that the world's fish catch has been declining since the late 1990s. Countries report their industrial catches to the United Nations Food and Agriculture Organization. But they do not report other kinds of fishing. This includes the catches of small commercial fisheries, which are called artisanal fisheries, and fishing for recreation and individual food.
Daniel Pauly at the University of British Columbia in Canada led the study. He noted that a huge amount of some catches is thrown away. “For example, shrimp trawlers (拖网渔船) keep only the shrimp and the fish that they catch — often eight to ten times as much as the shrimp — gets thrown away.”
Pauly told VOA that better estimates of the actual global catch will help ensure there will be enough fish in the future. “But our figures suggest that since 1996 a rapid decrease is happening. And if you project this forward you end up in a few decades having much less catch, literally no catch. So that is potentially dangerous.”
Researchers also found ways the world's fisheries are changing. They found that fishing fleets of larger nations are catching fish in the waters of developing countries more and more.
Pauly said he was surprised by the amount of fishing done by foreign fleets in competition with local fishers. “In West Africa, the figure that was most astonishing is the enormous role of foreign fishing — of European and Asian vessels fishing legally or illegally and competing against local fishermen. On the other hand for the US, Australia and some developing countries, such as the Bahamas, what was apparent is the enormous contribution of recreational fisheries, which also never get reported to the FAO.”
Researchers say inaccurate data also harms the development and supervision (监管) of effective policy and management measures.
语篇解读：世界范围内捕鱼的数量比报告中的数量要多很多，而这些虚假报告对经济和环境都造成了不好的影响。
1．What's the main idea of the passage?
A．False amount of fish caught worldwide harms economy environment.
B．The world's fish catch has been declining.
C．The global fishing competition is serious.
D．The management of global fishing needs improving.
解析：选A 主旨大意题。根据文章第一段第一、二句“The amount of fish caught worldwide is much larger than has been reported. And that could mean serious problems for the environment and nations that depend on fisheries(渔业)．”可知，本文主要阐述了关于捕鱼数量的虚假报告对环境造成了不好的影响。故选A项。
2．What does the underlined word “it” (in Para.1) refer to?
A．The amount of foreign fishing.
B．The amount of local fishing.
C．The amount of recreational fishing.
D．The amount of all fish caught worldwide.
解析：选D 代词指代题。it为代词，指代前文，又根据32 million这个数字可推断出it指代第一句中的“The amount of fish caught worldwide”，由此可知选D项。
3．Which kind of fishing has been reported to the FAO?
A．Industrial fish catches.
B．Commercial fishing.
C．Fishing for entertainment.
D．Fishing for individual food.
解析：选A 细节理解题。根据第二段二、三句“Countries report their industrial catches to the United Nations Food and Agriculture Organization. But they do not report other kinds of fishing.”可知，各国向联合国粮食及农业组织报告了他们的工业捕鱼量，但没有报告其他形式的捕鱼数量。故选A项。
