CPeople 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.”65. When a goby grows to within 5-10% of the size of its larger competitor, it .A. faces danger B. has breeding rightsC. eats its competitor D. leaves the group itself

CGUATEMALA CITY （Reuters） – A fish that lives in mangrove swamps（红树沼泽）across the Americas can live out of water for months at a time, similar to how animals adapted（适应）to land millions of years ago, a new study shows.The Magrove Rivulus, a type of small killifish, lives in small pools of water in a certain type of empty nut or even old beer cans in the mangrove swamps of Belize, the United States and Brazil. When their living place dries up, they live on the land in logs（圆木），said Scott Taylor, a researcher at the Brevard Endangered Lands Program in Florida.The fish, whose scientific name is Rivulus marmoratus, can grow as large as three inches. They group together in logs and breathe air through their skin until they can find water again.The new scientific discovery came after a trip to Belize.“We kicked over a log and the fish just came crowding out,” Taylor told Reuters in neighboring Guatgemala by telephone. He said he will make his study on the fish known to the public in an American magazine early next year.In lab tests, Taylor said he found the fish can live up to 66 days out of water without eating.Some other fish can live out of water for a short period of time. The walking catfish found in Southeast Asia can stay on land for hours at time, while lungfish found in Australia, Africa and South America can live out of water, but only in an inactive state. But no other known fish can be out of water as long as the Mangrove Rivulus and remain active, according to Patricia Wright, a biologist at Canada’s University of Guelph.Further studies of the fish may tell how animals changed over time.“These animals live in conditions similar to those that existed millions of years ago, when animals began making the transition（过渡）from water onto land,” Wright said.49. The Mangrove Rivulus is a type of fish that _______.A. likes eating nutsB. prefers living in dry placesC. is the longest living fish on earthD. can stay alive for two months out of water

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 ofhaiku 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 theexotic, 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 toappreciate the short form. of haiku. Like fishing, haiku writing can be done with minimalequipment. 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 areeverywhere. 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 aroundjust where we are. It does little good to only read of fishing off the coast of Japan whensitting 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 writinghaiku; 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 isA. the freedom to choose what we do with the product of each activityB. the delayed appreciation of both activitiesC. the thrill experienced when engaging in themD. 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 oftenB. to contrast it with meat and potatoesC. to give an example of an exotic dishD. as a metaphor for original Japanese texts(3). According to the author, haiku writers have to_·A. read about the process of haiku writingB. be observant of what is around themC. try to have their poems publishedD. get acquainted with Zen philosophy(4). The best title of this text would be_·A. Something fishy about haikuB. The forgotten skill of fishingC. Writing haiku is easyD. The art of writing haiku(5). The author's attitude towards haiku is_.A. positiveB. neutralC. indifferentD. negative

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 tunaB.tuna is more popular among consumersC.wild fish is more precious than farmed fishD.the prices of fish are in fact decided by FAO

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 extentD.fake or mislabeled fish will no longer exist in the sushi market.
