蓝色是建议修改,紫色是强烈建议修改,有什么不妥请指出><~
In the reading part(the reading material illustrate that) the genetically modified trees are more excellent than other speices of trees. But in the lecture the professor gives three reasons to contradict the point referring in the reading.
First, the passage says that the genetically modified trees are more resistant to serious conditions like pest(pests/pest invasions) than other kinds of trees, so they are (more likely)able to survive. The professor in the lecture points out that the normal various trees which are unmodified(个人认为这个修饰多余) have the diverse genes, so there must be certain speices(individuals /species指整个物种吧,而且听力里用的是individual) can prevent(escape) from being hurted if they meet(can handle) different kinds of serious situations such as the new pest or the changing of climate(climate change). However, the genetic modification make gene of the trees very uniform, so they can only be resistant to the ones having the specific gene. If these trees are suffering a intrusion of a new pest owning the new gene, they will be not able to survive and die out finally.(这两句话有点啰嗦,完全可以合并成一句,突出“会被一种灾难全部灭杀”就可以了)
Second, (contrary to the reading,)the lecture says that the cost of genetically modified trees are (actually) higher than those (of )non-modified trees. On one hand, the price of the seeds of modified trees will be higher than the non-modifed ones. On the other hand, when finishing buying seeds, the farmers are(will) still need to give money to the companies everytime they planted becase the law has regulated this(so). Therefore, from the cost aspect, the genetically modified trees are not better than the unmodified trees.
Third, the professor illustrates that the genetically modified trees are growing more aggressively than wild trees. Hence, they will be compete(听力里是outcomplete 言简意赅) for resources like sunlight and water which are also needed by wild trees, making wild trees die out. Thus, this is exactly opposite to the point of reading part.
显得有点头重脚轻,下次试试让三段的体积均衡起来~第一段偏啰嗦,第三段太过简洁,可以尝试在第三段加入更多听力的推理过程,或者阅读观点的简单陈述。还要注意一些小错误呀>,<~ |
