The best and most-commonly used sources for the pills we have are oily fish like salmon(畦)，mackerel and sardines.Many environmentalists fear that some species are being overfished for this purpose.We may have an endless voracity for fish oil, but we don’t have an endless supply of fish.
Menhaden, which is described as “a big-headed, smelly, foot-long fish”， is in great danger.Although prized for dinner in the 18th century, the species has become the unknown victim of the fish oil business, which presents us with potential sea fish.Menhaden filter-feed(滤食) almost entirely on algae(海藻)and is especially good at changing it into 3 fatty acids, which makes them a good target for fish oil companies.
One particular company, Protein of Houston, has been fishing 90 percent of the country’ s menhaden.It’s become such a big problem that 13 of the 15 Atlantic states have banned the company’s boats from their waters.Yet the company is still allowed to fish in North Carolina and Virginia, as well as federal waters；the company’s efforts result in the removing of half a billion menhaden every year.
Aside from running out a public natural resource for a company’s private profit, the damage to the ecosystem is cause for alarm.The muddy brown color of the Long Island Sound is the direct result of lacking water filtration(过滤)— a job that was once done by menhaden.
Menhaden keep the ocean waters of the Atlantic and Gulf coasts clean.A menhaden filters four to six gallons of water of algae in a minute, which prevents underwater dead zones.
Measures should be taken to avoid the overfished situation.Plant seeds such as flax seed, chia seeds, hemp seeds, and sesame seeds—and particularly their oils—are good vegetarian sources of omega-3 fatty acids, although the mix of specific acids is different from which one can get with fish.
1．Why does menhaden become a good fish for companies to make pills?
A．It is good at forming 3 fatty acids.
B．It feeds mainly on the harmful algae.
C．It is well-known for its rich protein.
D．It is relatively easy for companies to catch.
2．What does the underlined word “voracity” in Paragraph 1 mean?
A．Trouble. B．Shortage.
C．Resource. D．Appetite.
3．What does the author intend to suggest us in the last paragraph?
A．To grow more plants for their seeds to make oil.
B．To use some substitutes instead of more fish oil.
C．To call on the government to make laws in fishing.
D．To take part in more activities to protect the environment.
4．What is the best title for the text?
A．The broken natural ecosystem
B．The process of making fish oil
C．Bad effects of fish oil making
D．How to use natural resources
【语篇解读】 本文是一篇说明文。文章主要介绍了鱼油制造带来的不良影响以及避免过度捕捞的措施。
1．A 细节理解题。根据文章第二段“Menhaden filter-feed almost entirely on algae and is especially good at changing it into 3 fatty acids, which makes them a good target for fish oil companies.(鲱鱼几乎完全以藻类为食，并且特别擅长将其转化为3脂肪酸，这使得它们成为鱼油公司的一个很好的目标。)”可知，因为鲱鱼擅长形成3脂肪酸所以成为鱼油公司的目标。故选A。
2．D 词句猜测题。根据文章第一段“The best and most-commonly used sources for the pills we have are oily fish like salmon, mack erel and sardines.Many environmentalists fear that some species are being overfished for this purpose.(最好和最常用的药物来源是油性鱼类，如鲑鱼，鲭鱼和沙丁鱼。许多环保人士担心，一些物种正因为这个目的而被过度捕捞。)”以及“We may have an endless voracity for fish oil, but we don’t have an endless supply of fish.(我们可能对鱼油有无穷无尽的渴求，但鱼的供应却不是无穷无尽的。)”可判断，此处voracity指人们对鱼油的欲望、需求。故选D。
3．B 推理判断题。根据文章最后一段“Measures should be taken to avoid the overfished situation.Plant seeds such as flax seed, chia seeds, hemp seeds, and sesame seeds—and particularly their oils—are good vegetarian sources of omega-3 fatty acids, although the mix of specific acids is different from which one can get with fish.(应该采取措施来避免过度捕捞的情况。植物种子，如亚麻籽，交叉籽，大麻籽和芝麻籽，特别是它们的油，是很好的素食来源-3脂肪酸，尽管特定的酸的混合不同于鱼类。)”可判断，作者在最后一段介绍了避免过度捕捞的措施：用一些替代品代替更多的鱼油。故选B。
4．C 标题归纳题。根据文章第四段“Aside from running out a public natural resource for a company’s private profit, the damage to the ecosystem is cause for alarm.The muddy brown color of the Long Island Sound is the direct result of lacking water filtration—a job that was once done by menhaden.(除了为了公司的私人利益耗尽公共自然资源外，对生态系统的破坏也值得引起警觉。长岛海峡浑浊的棕色是缺乏水过滤的直接结果——一项曾经由鲱鱼完成的工作。)”以及全文内容可知，文章主要介绍了鱼油制造带来的不良影响，C选项“鱼油制造的不良影响”最适合作文章标题。故选C。
