阅读:
菊石(Ammonites,软体动物门头足纲的一个亚纲)是因为小行星撞击后的一系列影响而灭绝的。
1. 酸雨。小行星撞击后的酸雨,使漂浮在海平面上的菊石幼体死亡,所以导致了其灭绝。
2. 浮游生物(zooplankton)的死亡。小行星撞击使大量浮游生物死亡,而浮游生物是菊石的主要食物来源,菊石因食物匮乏而灭绝。
3. 氧气缺乏。小行星撞击造成氧气缺乏,所以菊石无法生存。
听力:
这三个理论都是不可信的。
1. 酸雨虽然会对菊石造成影响,但当时还有另一种生活在海里的frog,这种frog至今还在地球上存在,如果酸雨对菊石造成影响的话,这种frog也应该会灭绝,但是并没有。
2. 浮游生物(zooplankton)只是菊石食物的一小部分,在所有菊石种类中,只有个别种类以浮游生物为食,所以浮游生物的灭绝不会对大部分的菊石造成影响,所以该理论不成立。
菊石有特殊的身体组织,可以让它在低氧的环境下也能够呼吸生存,所以氧气缺乏也不是导致菊石灭绝的可靠原因。
满分范文:
The reading and listening both talk about whether the Ammonites died out due to asteroid apocalypse. However, the lecturer lists three reason to contradict what the passage indicates.
First, according to the lecturer, if the acid rains had killed off the ammonites on the surface of the water, another kind of frog, which also lived near the ocean, would become extinct as well. However, they still exist till now. Thus, the acid rain caused by asteroid impact mentioned in the reading passage was not the main reason.
Secondly, the reading passage indicates that the disappearance of zooplankton, which was the main food of ammonites, directly cause the extinction of them. However, zooplankton was just a small part of their food supply, according to professor, only a part of ammonites lived on zooplankton. Therefore, zooplankton didn’t account for that.
As to the third reason of absence of oxygen, the professor claims that the special physical structure allowed ammonites to live with hypoxia, which means that the statement in the reading that the impact taking away oxygen from the atmosphere killed all of ammonites is not correct.(185words)
