第3题：
Which of the following statements can best be inferred from the passage?
A. Fishes only "speak" to communicate with each other.
B. Researches are now being made to study the significance of fish sounds.
C. Sea animals have a sharper hearing ability than men.
D. Sounds made by fish cannot be transmitted through the air.
正确答案：B
答案为 B。根据第一段第二至第五句， Actually， their talk may be as meaningful as much of our own．For example，some sea animals use their "voices" to locate their food in the ocean expanses；others use their "voices" to let their fellows know of their locations；and still others，as a means of obtaining mates．Sometimes, "speaking" may even mean the difference between life and death to a sea animal．It appears in some cases that when a predator approaches，the prey depends on no more than the sounds it makes to escape 作出该项选择。选项 A中only不确切；选择 C和D在文中都没提到。 -
第4题：
Text 3 It is a good time to be a fisherman.The global fish-price index of the UN's Food and Agricultural Organization（FAO）hit a record high in May.Changing consumer diets,particularly in China,explain much of the sustained upward movement.High oil prices,which increase the cost of fishing and transportation,also add to the price of putting fish on Lhe table.Not all fish are creaLed equal,however.There are two types of fish production:"capture"（or wild）and"aquaculture"（or farmed）.And they seem to be on different tracks.Fish such as tuna,the majority of which is cau~;ht wild,saw much bigger price increases than salmon,which is easier to farm.Overall,the FAO's price index for wild fish nearly doubled between 1990 and 2012,whereas the one for farmed fish rose by only a fifth.What explains this big difference?The amount of wild fish captured globally has barely changed in the past two decades.The ceiling,of about 90m tonnes a year,seems to have been reached at the end of the 1980s.Overfishing is one reason,as is the limited room for produclivity growth,particularly if consumers want high quality.Patrice Guillotreau of the University of Nantes tells the story of a fleet in France that decided to trawl,rather than line-catch,its tuna.It braughi more back to shore,but the fish were damaged.It could not be sold as high-value fillets and was only good for canning.The old ways of catching fish are still best if you want the highest profits,says Mr CuiUotreau.In contrast,the farmed-fish industry continues to make productivity improvements.Fish farms have found crafty ways to use lower quantities of fish meal as feed.In the early days of aquaculture,it could take up to ten pounds of wild fish to produce one pound of salmon.Now the number is down to five.That may still be an inefficient use of protein,but the ratio is set to improve further.Fish farms have also become more energy-efficient,meaning that they are less affected by higher energy pnces.And they have learned how to handle diseases beUer,reducing the quanlity of fish that ends up being unsellable.As a resuli of all these improvements,the global production of farmed fish,measured in tonnes,now exceeds the producUon of beef.Output is likely to continue growing:the FAO estimates thal by 2020 it will reach six times its I990 level.
Tuna and salmon are mentioned to show that______A.salmon is not as expensive as tuna
B.tuna is more popular among consumers
C.wild fish is more precious than farmed fish
D.the prices of fish are in fact decided by FAO答案：C解析：例证题。根据tuna and salmon定位到第二段第四句。答案句来自下一句：Overall．the FAO's price index for wild fish nearly doubled between 1990 and 2012,whereas the one for farmed fish rose by only a fifth.文章举金枪鱼和三文鱼的例子，是为了说明野生鱼的价格涨幅大，而养殖鱼的价格相对涨幅小，即野生鱼比养殖鱼更珍贵，选项[C]wild fish is more precious than farmed fish“野生鱼比养殖鱼更珍贵”为答案。选项[A]salmon is not as expensive as tuna“三文鱼不如金枪鱼贵”“B]tuna is more popular among consumers“金枪鱼更受消费者欢迎”；这两项围绕salmon和tuna讨论，明显是表面选项，故可以排除。选项[D】the prices of fish are in fact decided by FAO“鱼类价格实际上由联合国粮食与农业组织决定”；该项表述纯属无中生有。综上，本题选择[C]。 -

According to Patrice Guillotreau,the price of wild fish is decided by its_____A.quality
B.size
C.quantiiy
D.popularity答案：A解析：细节题。根据Patrice GuilloLreau定位到第四段。题目问“野生鱼价格由什么决指野生鱼。本题答案句来自中间两句：It broughL more back to shore，but the fish were damaged.It could not be sold as high-value fiUets and was only good for canning.其中the fish指tuna。这两句说明，金枪鱼受损，就不能高价卖出，只能制作成罐头，暗示了野生鱼质量好才能卖出高价格，即野生鱼价格由其质量决定。上一段最后一句的if consumers want high quality也与本段内容有所关联，其中的high quality也是答案提示，故本题选择[A]quality“质量”。选项[B]size“大小”；[C]quantity“数量”；[D]popularity“受欢迎程度”；这三项均无法从文中找到对应内容，故排除。综上[A]正确。 -
第6题：
资料：There's a good chance that spicy crunchy tuna roll you ordered for lunch doesn't actually contain any tuna at all.
That's because 74% of fish sold at sushi venues in the US is mislabeled and often completely different than what's on the menu, according to a 2013 survey from the ocean conservation group Oceana.
But new technology could help make the seafood business a bit more transparent. Google is teaming up with Oceana and the aerial and satellite imaging nonprofit SkyTruth to launch Global Fishing Watch this fall, the New York Times reports. The initiative will track and analyze fishing boat practices using satellite technology and, ideally, help ensure that fewer fake or mislabeled fish are swapped in along the way.
Seafood providers are also investing in technology to reduce fraud. Boston seafood distributor Red's Best, for example, has increased transparency by selling fish with labels that buyers can scan with their smartphones to access a web page that provides details about the individual fish, including where the fish came from, the New York Times reports.
Even if a restaurant serves some real, correctly labeled fish, 95% of the 118 sushi restaurants surveyed by Oceana in cities including New York, Chicago, and Los Angeles had at least one faked sushi item on the menu.
Currently, the biggest culprits for fake sushi are snapper （92% misleadingly labeled） and tuna （71%）. White tuna is often swapped for escolar, which is sometimes called the "Ex-Lax Fish, " according to Inside Edition, because it can cause intestinal problems.
Roughly 75% of fish labeled snapper isn't even from the snapper family. Because of the predominance of fraud in the supply chain, New York sushi restaurant Sushi Nakazawa refuses to serve red snapper because the risk of fake fish is too high.
According to the passage, we can infer that______.A.Sushi restaurants verified by Oceana provide no fake fish.
B.it would be better not to eat sushi in America.
C.the new technology can help deal with the fake sushi to some extent
D.fake or mislabeled fish will no longer exist in the sushi market.答案：C解析：本题考查的是推理判断。

【解析】本题的问题是“根据文章，我们可以推断出_____”。 A选项“经Oceana认证的寿司店不提供假鱼。”；B选项“在美国最好不要吃寿司。”；C选项“这项新技术可以在一定程度上帮助处理假寿司。”；D选项“假冒或贴错标签的鱼将不再存在于寿司市场。”。根据主题句可知，A、B、D选项都说得太绝对了，故选C。 -

第14题：
Today a neighbor brought us some fresh fish he had caught on his last boat trip. As thanked him，he said,‘They are not from me; they only come through me.’
At that moment I noticed the similarity between fish and haiku.
Nowadays, if Mom doesn't ever serve fish for dinner at least the kids get a taste of
haiku at school.
For most of us，our first introduction comes from reading translations from Japanese,
which is a bit like comparing sushi to frozen fish sticks. Even with the knowledge of the
exotic, most poets stick to the meat and potatoes of English literature. It often isn’t until we get older that we accept the simple goodness of fish，adding them to the menu more often.
Having acquired a taste for fish and learned how to cook them, one is better able to
appreciate the short form. of haiku. Like fishing, haiku writing can be done with minimal
equipment. A pin or a pen，and a scrap of paper, is enough，but it is tempting to go all out and buy a rod and reel (even study Zen，visit a monastery or take a trip to Japan).
If one goes in for deep sea fishing,a computer and laser printer are soon on the list of 'must haves'.
Like fishing, to catch haiku you have to go where they are. Unlike fish, haiku are
everywhere. Still，you have to know the secret places where they hide and how to get there.
Wearing old comfortable clothes(usually thought of as a meditative state) we look around
just where we are. It does little good to only read of fishing off the coast of Japan when
sitting beside the lake by our own front door. It does help to know which fish are edible and which are not. There are two ways of finding this out. We can either eat everything we catch and publish what feels right, or we can read books containing others’experiences while making up our minds about what kind of fish to go for.
If we compare spending days on rough seas to fish or strolling on the beach writing
haiku; it is very easy for me to decide where my interest lies. Still I do love a fish dinner and I hope my neighbor enjoys my latest poems.
(1). The similarity between fishing and writing haiku the text does NOT mention is
A. the freedom to choose what we do with the product of each activity
B. the delayed appreciation of both activities
C. the thrill experienced when engaging in them
D. the limited resources required for practising them
(2). In paragraph 2，the author refers to sushi_.
A. to point out that the American eat frozen fish sticks more often
B. to contrast it with meat and potatoes
C. to give an example of an exotic dish
D. as a metaphor for original Japanese texts
(3). According to the author, haiku writers have to_·
A. read about the process of haiku writing
B. be observant of what is around them
C. try to have their poems published
D. get acquainted with Zen philosophy
(4). The best title of this text would be_·
A. Something fishy about haiku
B. The forgotten skill of fishing
C. Writing haiku is easy
D. The art of writing haiku
(5). The author's attitude towards haiku is_.
A. positive
B. neutral
C. indifferent
D. negative
参考答案C D B D A

第15题：
阅读文章回答第65~68题C People diet to look more attractive. Fish diet to avoid being beaten up, thrown out of their social group, and getting eaten as a result. That is the fascinating conclusion of the latest research into fish behavior. by a team of Australian scientists.
The research team have discovered that subordinate fish voluntarily diet to avoid challenging their larger competitors. “In studying gobies we noticed that only the largest two individuals, a male and female, had breeding （繁殖） rights within the group,” explains Marian Wong. “All other group members are nonbreeding females, each being 5-10% smaller than its next largest competitor. We wanted to find out how they maintain this precise size separation.”
The reason for the size difference was easy to see. Once a subordinate fish grows to within 5-10% of the size of its larger competitor, it causes a fight which usually ends in the smaller goby being driven away from the group. More often than not, the evicted fish is then eaten up.
It appeared that the smaller fish were keeping themselves small in order to avoid challenging the boss fish. Whether they did so voluntarily, by restraining how much they ate, was not clear. The research team decided to do an experiment. They tried to fatten up some of the subordinate gobies to see what happened. To their surprise, the gobies simply refused the extra food they were offered, clearly preferring to remain small and avoid fights, over having a feast.
The discovery challenges the traditional scientific view of how boss individuals keep their position in a group. Previously it was thought that large individuals simply used their weight and size to threaten their subordinates and take more of the food for themselves, so keeping their competitors small.
While the habits of gobies may seem a little mysterious, Dr. Wong explains that understanding the relationships between boss and subordinate animals is important to understanding how hierarchical （等级的） societies remain stable.
The research has proved the fact that voluntary dieting is a habit far from exclusive to humans. “As yet, we lack a complete understanding of how widespread the voluntary reduction of food intake is in nature,” the researchers comment. “Data on human dieting suggests that, while humans generally diet to improve health or increase attractiveness, rarely does it improve long-term health and males regularly prefer females that are fatter than the females’ own ideal.”
第10题：When a goby grows to within 5-10% of the size of its larger competitor, it .
A． faces danger
B． has breeding rights
C． eats its competitor
D． leaves the group itself
正确答案：A

The most suitable title for the text is_____A.Wild Fish:Demand Decides Price
B.The Rising Price of Rare Wild Fish
C.Ffumed Fish:Making Improvements
D.The Prices of Fishes:Rising Differently答案：D解析：主旨题。文章首段引出话题：全球鱼类价格上涨。第二段指出：并非所有鱼类都涨幅相同，并引出野生鱼和养殖鱼这两个种类．接下来几段分别讨论野生鱼和养殖鱼上涨幅度不同的原因。选项[A]Wild Fish：Demand Decides Price“野生鱼：需求决定价格”；该项突出讨论野生鱼．全文只有第三、四两段突出讨论野生鱼，该项属于片面选项，故排除。[B]The Rising Pnce of Rare Wild Fish“稀有野生鱼价格上涨”；该项同样突出野生鱼，与[A]-样为片面选项。[C]Farmed Fish：Making Improvements“养殖鱼：不断进步”；该项突出养殖鱼，而文章只有第五、六段重点讨论养殖鱼，该项同属于片面选项，故排除。[D]The Price of Fishes：Rising Differently“鱼类价格：上涨幅度不同”；该项符合文章主旨，尤其risinS differently强调了不同鱼类涨幅不同，故该项为答案。 -

The production of farmed fish is growing due to the following reasons except_____A.disease control
B.lower labour cost
C.energy conservation
