1、訓(xùn)練（ 九） 史地自然類 Killer whales in Alaska s Bering Sea have figured out an easy way to get fed. Instead of seeking out the fish themselves , the clever whales chase down fishing boats and steal the entire catch of the day , as much as 20 ,000 to 30 ,000 pounds. Killer whale “thieves ” are not a new pheno

2、menon.Japanese fishermen have reported being followed by killer whales since the 1950s. However , the increasing frequency of whale fish theft in the Bering Sea s continental shelf is now threatening the livelihood of fishermen. Paul Clampitt , a local fisherman , says his crew tried to keep the wha

3、les away with loud sounds. Though that worked for a short time , the whales now consider the noise “a dinner bell ” . Jay Herbert tried using sonar to keep the whales away. He also met with little success. According to the experienced fisherman , the smart whales deliberately seek out longliners （延繩

4、釣漁船 ）, and, all the first opportunity presented to them, steal the fish , leaving behind just the lips of the fish caught ! NOAAFisheries biologist John Moran is not surprised at the whales thieving skill. The expert says whales are skilled hunters who can distinguish the sounds of different boats a

5、nd even recognize the sounds of the operating system that places the fishing equipment into the ocean. The expert jokes , “Grabbing a fish off a line is nothing. ” Since they are social animals ,it is easy for whales to pass their skills on to others. Killer whales are not the only whale species tha

6、t have learned to steal from humans. In the Gulf of Alaska , sperm whales also conduct similar thefts. Longline fishermen off Washington , Chile , Australia , Hawaii , and many other countries have reported similar incidents. There is , unfortunately , no easy fix to this problem. One of the possibl

7、e solutions is using pot traps similar to the ones used to catch crabs. However , the cost of switching from longline to pot fishing is too high , especially for small-scale fisheries. There is also no guarantee that the catch will be safe from the intelligent whales which , many fear , will eventua

8、lly figure out how to open the pots ! 1. What concerns fishermen in Alaska ? A. The killer whales eating their fish. B. The decrease of numbers of whales. C. The killer whales chasing their boats. D. The high cost of operating fishing boats. 2. What may be the means to protect fishermen s catch at p

9、resent ? A. Loud sounds. B. Pot traps. C. Sonar. D. Dinner bells. 3. What can we know from the text ? A. Whales can learn from each other. B. Whales thieving skills surprise experts. C. Whales are able to communicate with fishermen. D. Killer whales are the most intelligent whale species. 4. What ca

10、n be the best title for the text A. Fishermen facing danger B. Whales teasing fishermen C. Thieves stealing from fishermen D. Whales living all over the world On a college camping trip , curiosity about waves and sand caused Rob Thieler to study shorelines around the world. Thirty years later and no

11、w a US Geological Survey research geologist , Thieler , is combining science and smartphone technology to help study an endangered bird , the Atlantic Coast piping plover. The piping plover is a shorebird that breeds （繁殖）along the Atlantic Coast, the Great Lakes and the Great Plains. Rising sea leve

12、l associated with climate change , as well as increased development in their beach habitats （棲息地） , threatens the species （物種）. To help track changes in piping plover habitats , Thieler developed a free app called iPlover in 2012. This is a marked change from the typical way scientists collect data,

13、 which involves gathering information using specialized equipment or writing in notebooks and then putting into spreadsheets. Since releasing iPlover , scientists have gathered data across 1 ,500 km of breeding range. That equals about a third of the distance across the US, which is a large area to

14、cover for only two thousand breeding pairs of piping plovers on the east coast. Instead of having to travel and spend days at each site , a number of cooperators in the field use the app to collect and send data, allowing scientists to gather data more efficiently. It also allows them to collect dat

15、a at the sametime during each breeding season, providing a better picture of changes that happen over longer periods of time. And fast , centralized access means scientists can look at data quickly to get a real-time idea of where and how piping plovers are using their habitats. While iPlover is use

16、d by trained field staff , other apps like the US Geological Survey s web-based “iCoast Did the Coast Change?” invite citizen scientists to identify coastal changes by comparing bird s-eye view photographs taken before and after storms. All the information scientists and citizen scientists alike col

17、lect helps federal and state agencies create policy plans for addressing climate change impacts （影 響） worldwide. 5. What can we know about the piping plover ? A. Its behaviour is changing. B. Its habitat is growing bigger. C. Its living environment is becoming worse. D. Its breeding is limited to the Atlantic Coast. 6. Why did Thieler develop iPlover ? A. To study shorelines across America. B. To adv
