otter is killed by a predator, it’s eaten immediately so it can’t wash up on shore.主體段二:Second, although orcas may prefer to hunt whales, whales have essentially disappeared from the area because of human hunters. That means that orcas have had to change their diet to survive and since only smaller sea mammals are now available, orcas have probably started hunting those. So it probably is the orcas that are causing the decline of all the smaller sea mammals mentioned in the passage the seals, the sea lions and the sea otters.主體段三:And third, the uneven pattern of otter decline is better explained by the orca predation theory than by the pollution theory. What happens to otters seems to depend on whether the location where they live is accessible to orcas or not. In those locations that orcas can access easily, the number of sea otters has declined greatly. However, because orcas are so large, they can’t access shallow or rockylocations. And shallow and rocky locations are precisely the types of locations where sea otter populations have not declined.216。 模板三:閱讀聽(tīng)力獨(dú)立模板三點(diǎn)對(duì)點(diǎn)模板VS. 塊對(duì)塊模板開(kāi)頭段:It is not hard to find that some serious doubt has been cast by the lecture on the information in the reading passage.
