Scientist in Canada say big ocean fish have almost disappeared from the world since the start of industrial fishing in the nineteen-fifties. The scientists found that population of large fish like tuna, swordfish and cod have dropped by ninety percent in the past fifty years.
The study took ten years. The researchers gathered records from fishing businesses and governments around the world. The magazine Nature published the findings.
The scientists say the common method called longline fishing is especially damaging to populations of large fish. This method involves many fishing lines connected to one boat. These wires can be close to one-hundred kilometers long. They hold thousands of sharp metal hooks to catch fish.
Longline fishing is especially common in the Japanese fishing industry. Records showed that Japanese boats used to catch about ten fish for every one-hundred hooks. The study says longline fishing boats now might catch one fish per hundred hooks.
The scientists say industrial fishing can destroy groups of fish much faster than in the past. The study suggests the whole populations can disappear almost completely from new fishing areas within ten to fifteen years.
Ransom Myers of Dalhousie University in Nova Scotia led the study with Boris Worm of Dalhousie and the University of Kiel in Germany. Mister Worm says the destruction could lead to a complete re-organization of ocean life systems. Mister Meyers says the decreased numbers of large fish is not the only worry. He says even populations that are able to reproduce do not get the chance to live long enough to grow as big as their ancestors. He says not only are the fewer big fish, they are smaller than those of the past.
American government scientists say even with the best efforts to protect fish populations, decreases are to be expected.

U.S. airlines are seeing a major interruption because of hundreds of flights canceled due to the ash cloud from the Icelandic volcano, but European flight companies will face the biggest losses.
The airline business has been tough: The decline dramatically slowed traffic; February heavy snow forced U.S. airlines to cancel thousands of flights; and now the ashes from the volcano stopped all traffic in and out of northern Europe for days.
"For U.S. flight companies, it'll be a relatively short-term hit," said Michael Boyd, president of Boyd Group International, an aviation (航空学) consulting firm. "We think right now they're down about $80 million in terms of lost income, and they're down domestically about 80,000 passengers that would have been flying domestically but aren't because they can't get here."
Delta announced that volcano-related interruption grounded about 400 flights until Monday at a cost of $20 million in lost revenues. But compare that to the recent snowstorms, when the airline canceled 7,000 flights and lost $65 million in revenue.
The disruption has created uncertainty for customers, but analysts say U.S. airlines won't face as many costs as you might think. They are not flying in extra planes to handle the passengers in trouble because, airline analyst Robert Mann said, companies simply don't have them.
"Airlines run a very lean operation now," Mann said. "So, since there are no spare aircraft or crews, the airlines will attempt to maximize loads on every one of their aircraft that do fly. But it may take days, or in some cases a week or so, to get some of these customers to where they want to go."
46. Which negative consequences mentioned in the passage did the disasters cause?
A. coldness, pollution and airlines’ losses
B. airport damage, pollution and slow traffic
C. passenger delay, coldness and airport damage
D. passenger delay, airlines’ losses and slow traffic
47. Which of the following statements is true according to the passage?
A. The fewest airplanes will fly the trapped passengers to their destinations.
B. All the customers are sure to be sent to their destinations in time.
C. The U.S. and U.K. airlines suffered the same losses in the natural disasters.
D. The volcano eruption reduced the traffic to and from northern Europe.
48. What does the last paragraph mainly tell us?
A. the troubles that the airlines will face after the ash cloud disappears
B. the measures that the airlines will take to maximize their profit
C. the present situation of the airlines and their plan to deliver the passengers
D. the reasons why the airlines run a fine operation
49. Why will it take a long time for airlines to send the passengers to their different destinations?
A. Because the passengers enjoy staying in airports to talk with one another.
B. Because the airlines don’t have spare planes or employees to serve.
C. Because the airlines don't have enough financial support after the disaster.
D. Because the passengers are asking for full refund from the airlines.
50. The passage is most probably from_______.
A.a novel B.a news report
C.a magazine D.a thesis

Shopping for clothes is not the same experience for a man as it is for a woman. A man goes shopping because he needs something. His purpose is settled and decided in advance. He knows what he wants, and his objective is to find it and buy it; the price is a secondary consideration. All men simply walk into a shop and ask the assistant for what they want. If the shop has it in stock, the salesman promptly produces it, and the business of trying it on goes forward at once. All being well, the deal can be and often is completed in less than five minutes, with hardly any chat and to everyone's satisfaction. For a man, slight problems may begin when the shop does not have what he wants, or does not have exactly what he wants. In that case the salesman, as the name implies, tries to sell the customer something else, he offers the nearest he can to the article required. No good salesman brings out such a substitute without least consideration; he does so with skill and polish(完美): “I know this jacket is not the style you want, sir, but would you like to try it for size. It happens to be the color you mentioned." Few men have patience with this treatment, and the usual response is: “This is the right color and may be the right size but I should be wasting my time and yours by trying it on.
Now how does a woman go about buying clothes? In almost every respect she does so in the opposite way. Her shopping is not often based on need. She has never fully made up her mind what she wants, and she is only “having a look round". She is always open to persuasion: indeed she sets great store by what the saleswoman tells her, even by what companions tell her. She will try on any number of things. Uppermost in her mind is the thought of finding something that everyone thinks suits her. Contrary to a lot of jokes, most women have an excellent sense of value when they buy clothes. They are always on the lookout for the unexpected bargain. Faced with a roomful of dresses, a woman may easily spend an hour going from one rail to another, to and fro often retracing her steps, before selecting the dresses she wants to try on. It is a tiresome process, but apparently an enjoyable one. Most dress shops provide chairs for the waiting husbands.
According to the passage, a man’s shopping is based on _______.
A.his money B.his hobbies C.his need D.his friends
Why does a lady welcome suggestions from anyone while buying a dress?
A.Because she wants to buy a dress that every one thinks suits her.
B.Because she doesn’t know how to buy a dress.
C.Because she doesn’t know whether to buy it or not.
D.Because she wants to show herself off in public.
Which of the following statements is TRUE according to the passage?
A.Most men have patience with trying it on while buying a jacket.
B.Most women have a poor sense of value when buying a dress.
C.A woman’s shopping is based on her need. k+s-5#u
D.A man doesn’t pay much attention to the price of the clothes he wants to buy.
The passage mainly talks about the ______ between men shoppers and women shoppers for clothes.
A.similarities B.differences C.varieties D.intentions
