The lecture apparently disproves what is argued in the reading material. According to the passage, the number of the Torreya taxifoha, a type of tree that once lived in Florida, began to decline (tree decline,不是number decline,应该逻辑语法上不太对)since 1950s. Scientists offered three ways to solve this problem, including reestablish Torreya in the same location, move it to a new location and preserve it in research centers. However, the professor in the lecture asserts that a closer scrutiny of this argument would reveal how flimsy it is. She then represents (想用present用成了represent?)several evidences to demonstrate her statement.
To begin with, supposition give by the author states (state的用法虽然说supposition也说得通,但最好还是用人做主语吧,而且author 要表达清楚是passage还是reading的。)that Torreya has lived in Florida(for) thousands of years, the reestablish (reestablish是动词,不是名词)in the same place will work. But the professor claims that the global warm and some other factor(s) have changed the climate of Florida, the Torreya can not survive in the same place. Obviously, the speaker’s argument disapproves it counterpart in the reading.(细节内容不太充分)
Furthermore, the passage assumes that move Torreya to a new place may can help in keeping the trees. The professor, however, suggests that move the Torreya to a new place may be (move 是动词,move is。。。词性使用错误)very dangerous for the native plants. She assets that, for instance, a kind of tree has been replanted in a new environment, and killed other native plants, because it has a more strong ability to get sunlight and other resource.(听力原文理解不准确)
Moreover, the professor indicates that reserve Torreya in the research center is also not a (reserve。。。is词性错误)good choice whereas the author of the reading claims that reserve Torreya in the research center will ensure the continued survival of the species. The professor proves that this claim is indefensible by pointing out that Torreya need a large space and diversity condition to keep alive, but the research center can not provide these conditions.
In conclusion, taking account of the arguments offered above, the lecture clearly identifies the defects of the three ways to reserve Torreya of the reading material and forcefully showed that the methods given by the author are utter nonsense.(此段大都可以不写,写了不加分,不如用更多时间来把前三段弄好)
另外,逻辑链上感觉套用模板的痕迹略重
