【试题】

　　An endangered species of whale [19] is experiencing a small baby boom of the coast America. The north Atlantic white whale is one of the rarest species on the planet, numbering only about 411. But the center of coast studies said Friday that this area’s survey team spotted a mom with two babies inCape Cod bay a day earlier. That brings the number seen in nearly waters alone this year to 3. That’s big news because the whale population has been falling and no baby whales were seen last year. In all, seven baby whales have been spotted so far this year. [20] The whale population has become endangered due to commercial whaling activities in recent years. This is because they are sometimes hunted for their meat or their skin. Over-hunting could lead to the disappearance of the whale population, possibly causing major problems to the global food chain. [21]The whales give birth off the southeast coast of American in the winter and travel to feeding grounds off the northeast coast in the early spring. Northeast coast is a critically important source of food. The animas often feed close to shore. This provides watches on land with unbeatable views of one of the rarest of marine mammals. It is illegal to get within 1500 feet to the animals without federal research permit, so well watchers are discouraged from the tempting to get to the whales.
