今天练习了tpo49的综合写作
阅读材料如下
Like many creatures, humpback whales migrate long distances for feeding and mating purposes. How animals manage to migrate long distances is often puzzling. In the case of humpback whales, we may have found the answer: they may be navigating by the stars, much as early human sailors did. What we know about humpback whales makes this a distinct possibility.
First, humpback whales seem to be intelligent enough to use stars to navigate by. Whales' brains have a high degree of complexity'a common determiner of intelligence. This suggests that the whales' brain power far exceeds that of most other animals. The whales' well-developed cognitive ability seems to provide a sound basis for the ability to use a complex, abstract system of sensory stimuli such as the night sky for orientation.
Second, humpback whales migrate in straight lines. Animals can maintain movement in a straight direction for long distances only if they orient themselves by some external objects or forces. Many birds and other terrestrial creatures, for example, use physical landmarks to help them stay on track as they migrate. Whales, which swim in the open ocean, cannot rely on land features; they could, however, rely on stars at night to provide them with external signs by which to maintain direction over long distances.
Third, humpback whales exhibit an unusual behavior: they are sometimes observed floating straight up for minutes at a time, their heads above the water as though they were looking upward. The behavior is known as spy-hopping, and it is very rare among marine animals. One explanation for the function of spy-hopping is that the whales are looking at the stars, which are providing them with information to navigate by
文章主要讲到了座头鲸的迁徙时具有navigating by the stars 的能力,然后开始分析为什么会有这种能力。
第一段提到了关键词intelligent,然后说他们有well-developed cognitive 去干嘛干嘛,
第二段提到了迁移路线是straight lines 然后说动物迁徙的路线需要有external objects的作用。
第三段提到了这种奇怪的spy-hopping行为,然后猜测可能是这样子为了看星星。
笔记内容:
migrate/stars
1.intelligent enough to use star+brain
2.move in straight lines
3.unusual behavior+spy hopping
听力里面这个教授不出意外的来反驳作者了,首先就表明了这个作者的说法not convincing。然后一个一个的怼。
第一点就说there's no connection between 用星星导航和智力的关系, 然后就开始举例说其他的有些动物比如有些鸟啊就有这种能力,可它们并不intelligent,说明这种能力是天生的。
第二点,这个教授说有其他的解释他们迁移in straight night,不是因为他们看星星而是他们能够感觉到磁场的。
第三点说用了sharks来反驳,说sharks也会spy-popping,然而sharks并不migrate。
笔记内容:
not convincing
no connections/birds not intelligent
sense external force/meganetic field
rare/sharks
speculation
然后就开始写作了(这篇写了很久,之前提到了我基础很差是真的很差。。)
In the reading material, the writer try to explain the reason why the humpback whales' migrate for a long distance without missing by being aware of the stars and this is proved by their high intelligence, routines of traveling and strange behaviors. However, in the lecture, the professor uses several examples of other animals and an analysis to rebut the passage.
At first, the professor states that there not radical connection between intelligence and migration led by the stars. The professor mentions that some birds have the ability to migrate and tell the direction by following the stars but fact is they are not so clever. So even though the humpback whales are intelligent, they may not necessarily know how to use star to migrate.
Second, the writer claims that the routines of humpback whales are quite straight and not like other animals, the whales don’t have external objects to rely on as a cue to find their ways, thus the stars must be a sign for the whale. On the contrary, the professor mentions a specific part of the whales’ brain that enable them to sense the magnetic field to tell the direction.
Third, when it comes to the strange behavior called spy-hopping mentioned by the writer which proves the whales’ ability to identify the stars. While the professor states the behavior is not that rare because some other marine animals also act the same for example, sharks behave like that but they don’t migrate. What’s more, the whales jump above the water during a day when there’s no star. That is to say the aim of whales’ spy-hopping is not to see the star.
