材料要点重现：lecture中教授的观点是球接子类生物与阅读文章中提出的三个理论不符。证据有三个，第一它们不可能是自由游动的捕食者，由于它们的眼睛太小甚至是瞎的，无法在海底捕捉猎物。第二它们不可能是海底居住者，因为球接子类生物活动范围跨越很广。第三们不可能是寄生生物，因为某些球接子类生物数量庞大。
高分词汇：inhabited，maintains，remain，unconvincing
范文：The reading mainly presents that there are three theories about how agnostids may have survived. However, the listening challenges what are stated in the passage by providing three strong evidences.
Firstly, in the reading, it is said that the agnostids may have been free-swimming predators that feed on smaller animals since other types of primitive arthropods were strong swimmers and active predators. In contrast, the listening holds an opposed view that the eyes of agnostids are too small, and there is no evidence of fossil record of their special sensory organs to catch up prey.
Secondly, the passage asserts that agnostids may have inhabited on the seafloor. However, the professor also maintains an opposite opinion that many agnostids species dwelled on multiple geographic areas. Because seafloor dwellers move slowly across the seafloor and remain living in localized areas.
Finally, the author of reading passage believes that many species of modern-day arthropods exist as parasites. On the other hand, the lecturer disagrees it with the point that the populations of parasites are not very large. Since too many parasites would kill off the host organisms they live on. However, the populations of many agnostids were in fact very large.
Under this circumstance, the third theories made by the reading passage is unconvincing.
