Big ocean（海洋） fish have almost been endangered since the start of business fishing in the 1950s. The scientists found that the number of large fish has dropped by 90 percent in the past fifty years. The study took ten years. The researchers（研究人员）collected records from fishing businesses and governments around the world. The magazine Nature published(发表) the findings.
The scientists say the common way called long-line fishing is especially harmful to large fish. This way includes many fishing lines that are connected to one boat. If these lines are joined together, they can reach one hundred kilometers. They hold thousands of sharp metal hooks(钩) to catch fish. Long-line 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 long-line fishing boats now might catch one fish per hundred hooks.
The scientists say business fishing can destroy groups of fish much faster than in the past. It’s not the only worry that the number of large fish is becoming smaller and smaller. What’s worse, they are smaller in size than their ancestors（祖先）.

China says 16 endangered finless porpoises（江豚）have been found dead since the beginning of the year and experts blame water pollution and climate change for pushing the species toward extinction．
The freshwater porpoise-popularly known in Chinese as the"river pig"-mainly lives in China's Yangtze River and two lakes linked to the river．
Authorities（官方）have discovered 10dead porpoises in Dongting Llake in the central province of Hunan since March, according to a statement by the government of Yueyang City, which is located on the lake's shore． Another six dead porpoises have been found in Poyang Lake in the eastern province of Jiangxi since the beginning of the year． Experts warn that the species will be extinct within a matter of years．
Wang Kexiong, a researcher at China's Institute of Hydrobiology, said water pollution, shipping and sand dredging（挖掘）were all possible contributing factors to the recent deaths．
Many rivers in China have become heavily polluted with poisonous waste from factories and farms-pollution blamed on more than three decades of rapid economic growth and slow enforcement（实施）of environmental protection laws．
The report said climate change also could be to blame as the dry weather has caused water levels to drop and makes it more difficult for the porpoises to find food． Tests have shown that some of the porpoises are believed to have died of starvation（饥饿）．
In 2006, China was estimated（估计）to have only 1,200 finless porpoises left． That same year, the Baiji-a freshwater dolphin also native to the Yangtze River-was declared extinct． Earlier this year, a survey found just 65"river pigs"in Dongting Lake and 300-400 in Poyang Lake．
Following the recent deaths, Yueyang City promised to investigate and increase protection of the remaining porpoises in Donting Lake．
1.How many river pigs are estimated to live in Dongting Lake？
A.49
B.55
C.59
D.65
2.The following factors of river pigs' deaths are mentioned EXCEPT__________．
A.water pollution
B.climate change
C.food shortage
D.illegal fishing
3.We can learn from the text that__________．
A.river pigs' deaths can be reduced if measures are taken in advance
B.river pigs' deaths are completely caused by human beings' activities
C.climate change is likely to stop economic growth in China
D.economic growth always has a negative effect on the environment
4.The number of river pigs is listed in Paragraph 7 to________．
A.show they have become extinct
B.call for more effective protection
C.show they are on the edge of extinction
D.show the importance of raising them in labs

With only fish and birds for company, Eric Erden has been rowing across the Pacific Ocean to Australia in his 23-foot-long boat since he left California on July 10, 2009.
But crossing the Pacific is only part of his incredible journey. Eric has decided to go all the way around the world using only his own energy. He will row, bike, and walk without help from any motors at all. Oh, and his plan includes climbing the tallest peak on six of the continents along the way, to honour the memory of a fellow climber.
He says he is doing this to show kids that they can achieve any goal, but he hopes to have some great adventures along the way.
As a solo traveller, Eric has already faced disappointments and challenges. Because he has to row about ten hours a day, he brought along an MP3 player to listen to music and pass the time. Unfortunately, the nearly daily tropical rain for several months has forced him to keep his player packed away where it's safe and dry.
Storms and huge wave wind regularly force him in the wrong direction and even threaten to overturn his boat. “Sometimes I really feel scared,” says a somewhat embarrassed Eric. “But that’s all part of the journey. I knew this wouldn’t be easy when I started. That's why I gave myself two years to finish.”
Protein bars（蛋白棒） give him energy, and he boils water to heat freeze-dried meals on a one-burner stove. A solar-powered machine removes salt from ocean water so he can drink it, but only when the sun shines. When that fails he sometimes tries to collect rainwater in buckets.
He’s not bothered by any of the hardships. Eric sees the world as a laboratory where there is much to learn. And when his trip around the world takes him across land, he enjoys meeting people - especially children. He has already visited several schools and shared his story.
1.Why is Eric making this trip?
A. To encourage children to reach for their goal.
B. To learn more about the world around us.
C. To have many great adventures in strange lands.
D. To honour the memory of a fellow climber.
2.What does Eric plan to do on each of the six continents he will visit?
A. Visit schools to share his story.
B. Study the culture of the local people.
C. Climb the tallest mountain.
D. Cycle from one end to the other.
3.When does Eric expect to finish his journey?
A. July 2009. B. June 2010.
C. January 2011. D. July 2011.
4.Which of the following words best describes Eric’s character?
A. Determined. B. Intelligent.
C. Fearless. D. Lonely.

Later, I ran away.

Tommy White has been rowing across the Pacific Ocean in a rowboat since he left California on July 10 ,2007. He has been heading for Australia with only birds, fish, and sharks ever since.
Crossing the Pacific is only part of his journey. Tommy has decided to go all the way around the world using his own energy. He will row, bike, walk, and climb the world without help from any motor (马达) at all. His plan includes climbing the tallest peak on six of the continents (大陆) along the way.
For the first part of his trip, he bicycled 5,546 miles from Seattle, Washington to Mount Mckinley in Alaska and back, walked 67 miles to base camp, and climbed 20,320 feet to Mckinley's top. Now in the second part of his dangerous trip, he is rowing to Australia.
Why would he try to go around the world this way? He explains that he wants to encourage kids to dream their dreams and get to their own goals. He wants to show kids that there might be hard parts along the way, and sometimes they might not even get to that final goal. But they can have great adventures and learn a lot along the way.
Tommy has already faced some difficulties. For example, wind and waves keep pushing him westward when he wants to go south toward the Solomon Islands. If his luck doesn’t change, he will cheerfully change his plan, and aim to land at Papua New Guinea. One way or another, he's sure he’ll get to his next goal： Australia.
When his trip around the world takes him across land, he enjoys meeting people — especially children. He has already visited many schools and shared his story.
Tommy encourages all kids to set their eyes on a goal and not to give up. He says, "With goals, we will make progress, and we will be farther along than when we started, even if we don't get to some goals. That's called life! ”
1.How has Tommy decided to go all the way around the world?
2.Which part of his trip is he in now?
3.If his luck doesn’t change, where does he aim to land?
4.What does he enjoy on his trip across land?
5.To Tommy, does life mean struggling for (为… 而奋斗)the goals?
