Both the lecturer and the writer are discussing about the situation of decline of yellow cedar populations. The writer suggests three hypotheses to explain this phenomenon. On the other hand, the lecturer asserts the writer's arguments are not plausible.
To begin with, the lecturer claims that insect parasites including the cedar bark beetle cannot be the factor of the major reason of the decreasing number of declining the yellow cedar trees. This is because the species are strong enough to resist the beetle. To be specific, they have powerful toxic chemical substances to overcome infestation. Therefore, it is unlikely to suffer due to the beetle. 요약문은 최대한 불필요한 설명을 배제해주는 편이 좋습니다.This counters the reading passage's idea that the cedar bark beetle would be the reason of dying the dying yellow cedar. 대립되는 point가 명확하고 내용 정리에 필요한 detail들도 잘 잡아내신 것 같아요^^
Next, the lecturer insists that brown bears are not responsible for declining the yellow cedars, comparing the bears' living area with the trees' habitat. The yellow cedars still have been dying in some regions where the bears are not living. This contradicts the reading passage's claim that brown bears' aggressive feeding habit like clawing to consume sugar and berries would lead the yellow cedar to the crisis of its population numbers. brown bear를 원인으로 보는 reading과 lecture의 반박 구도가 잘 정리된 문단입니다.
Finally, the lecturer argues that the climate alteration did not significantly affect the problem of the yellow cedars. According to the lecturer, the trees have been dying in the low elevation, where it is warm. However, the elevation has to be higher, in other words the place has to be cold, for making influences on the trees by freezing their roots. 문장을 더 간결하게 다듬어서 "나무의 뿌리를 얼릴 정도로 차가우려면 고도가 더 높아야 한다"하는 한 문장으로 정리해주면 더 좋을 것 같아요. This goes against the reading passage's assertion that gradual change of climate freezes the tree’s roots, and leads them to be dead.
