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.
1. Where is the passage probably taken from?
A. A story book. B. A business magazine C. An environment report D. An economic survey
2. Big fish have gradually been disappearing especially because ________.
A. longline fishing method is used B. sea water is getting polluted
C. mankind destroys the environment D. governments don’t make the best efforts
3. Which of the following shows the fact that the populations of large fish have dropped?
A. Today’s “large” fish are smaller than those of the past.
B. Longline boats now might catch fewer fish every one-hundred hooks.
C. Fish even able to reproduce don’t have the chance to live longer.
D. Industrial fishing is an effective way to catch fish.
4. What can be the best title?
A. Discoveries Canadian Scientists Have Made B. Japanese Fishing Industry
C. Losses of Big Fish D. Modern Fishing Methods
5. When did the researchers begin to survey the decreasing of large fish?
A. In the 1960s B. In the 1970s C. In the 1980s D. In the 1990s

Finding fish is going to get harder as climate change continues to heat the world's oceans. A new study finds that warming seas over the past 80 years have reduced the sustainable catch of 124 species of fish and shellfish. Sustainable catch refers to the amount that can be harvested without doing long-term damage to the health of populations of some species.
Overfishing has made that decline worse, researchers say. Overfishing refers to catching so many fish that the size of the population falls. In some parts of the world, such as the heavily fished Sea of Japan, the decrease is as high as 35 percent. That's a loss of more than one in every three fish.
Researchers examined changes in 235 populations of fish and shellfish between 1930 and 2010. Those fish populations spread far apart across 38 ocean regions. Temperature changes vary from one ocean site to another. But on average over that time, Earth's sea-surface temperatures have risen by about half a degree Celsius.
On average, that warming has caused the sustainable catch to drop by 4.1 percent, the study found. About 8 percent of the fish and shellfish populations the team studied saw losses as a result of the ocean warming. However, about 4 percent of some populations increased. That's because certain species have thrived in warmer waters. One example is a kind of black sea fish. It lives along the northeastern U.S. coast. As warming continues, these fish will reproduce faster until they reach their limit.
About 3.2 billion people worldwide rely on seafood as a source of food. That means it's urgent for commercial fishing fleets and regulators to consider how climate change is affecting the health of all of those fish in the sea.
1.What does the new study discover？
A.Overfishing is to blame for fish health.
B.Warming seas cause fewer fish and shellfish.
C.Seafood matters to people's health worldwide.
D.The living regions of fish and shellfish are different.
2.What does the underlined word "thrived" in paragraph 4 probably mean？
A.Survived narrowly. B.Disappeared soon.
C.Decreased sharply. D.Developed quickly.
3.What do we know about species of fish and shellfish？
A.About 8 percent of them suffered from a great loss.
B.About 35 percent of them survived in the Sea of Japan.
C.About 3.2 billion species have been saved up to now.
D.About 80 species have died out because of warming seas
4.What is the author’s attitude towards the new discovery?
A.Satisfied B.Not interested
C.Worried D.Terrified
