问题 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.According to Patrice Guillotreau,the price of wild fish is decided by its_____A.qualityB.sizeC.quantiiyD.popularity
选项 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。
