很好 建议或修改 The reading passage and the listening lecturedeals with an argument that whether the cedar bark beetles, brown bears and thegradual changes of the climate giverise to the decline of the yellow cedar. These two offer two opposing opinions.
First of all, the lecturer said owing to the poisonouschemicals stuck to the bark of the yellow cedar, the yellow cedar (they) can protect itself(themselves)from the threats of the insect parasites more than othertrees. In that way, the view in the reading passage is totally wrong: if it is safer than othertrees, why only the yellow cedar is likely to decline? (能补充点阅读中的内容更好)
Furthermore, the author stated that it is brownbears that have eaten these yellow cedar trees. However, the listening lectureprovided the evidence that even if in the islands which brown bears cannot stepinto, the yellow cedar also(still) suffer to the decline. (这一段也需要再充实一下)
Finally, the reading passage blamed (attributed )thedecline of the yellow cedar to the changes of the climates, because of thefrost damage. But the reality is that(As a matter of fact,) in a higher area, which means in a lower-temperature area,fewer trees die than that in lower area. So according to the lecturer, thisview is also problematic.
In a word, these explanations offered by theauthor are not adequate to explain for the decline of the yellow cedar. 很少发现语法错误, 有的用词我觉得换一下更能表达一些逻辑, 内容可以再多点, 因为我听过的所有建议都是 要尽量包括听力中的细节。 但是楼主的文章似乎属于短小精悍型的。还是希望多加点听力中的细节, 争取250-300字吧。 我确实看错了是 Bear。。。 |
