The reading passage explores the benifits of the salvage logging,while the professor diagrees with what the reading passage stated for the following reasons.
To begin with,the reading passage suggestsed(时态保持一致吧) that the salvage logging can remove the remains of the dead trees,thus making room for the fresh growth. However,the lecturer argues that the cleaning up of dead trees can also lead to the loss of nutrients in the soil which definitely necessarily contributes to the growth of trees.
In addition,the satatement in the reading shows that decaying woods may lead to the insect habitat which can damage live and healthy trees.The professor opposes it by pointing out that these insect habitats may not cause much harm as expected.In fact,the salvage logging does more harm than does the insects.This directly contradicts with the counterparts in the reading. (丢了一个点,说不仅带来有害的昆虫,还会招来鸟类等益虫。)
last,though the reading passage reveals that salvage logging has ecnomic benifits by providing much wood in need and addition jobs for local residents,however,the professor contends that this kind of benifits is temporary. Employers may apply helicopters and vehicles rather than laborers and tend to hire experienced workers.
In conclusion,the professor identifies the weaknesses in the reading passage (有点不对劲, weakness of points ?)and shows the salvage logging is not a good way to deal with remains in the forest disasters.
