First of all, the lecturer asserts that the(此处特指是否必须)natural trees may be survived in few amounts if suffered from climate changes and insect infections(这样and前后一致不知会不会好点) because of their genetic diversities. On the contrary, the genetically modified trees lack of genetic variety. Therefore, they might die away in some (这个some是否可以去掉,然后under certain )certain conditions.
Moreover, the lecturer argues that although cultivating genetically modified trees can bring economic benefits, it will cost much more than growing natural trees. For one thing, the farmers would pay more to buy the seeds of genetically modified trees. For another thing, it is cited in the contract(law是国家法律)that farmers should pay company money once they plant a genetically modified tree. As a result, considering the hinder costs, they may not get more benefits than growing unmodified trees.
Finally, the genetically modified trees may spread aggressively. They will compete with native trees for nutrient elements in the soil(建议去掉,保持并列的平衡和词义楚), sunlight, water and spaces. Consequently, genetically modifies trees will damage native trees other than preventing them from destroy. This directly contradicts what the passage indicates.
To sum up, the contents narrated in the passage are totally jeopardized by the professor, and the professor has completely different points.

In the reading passage, the writer claims that growing genetically modified trees will bring a lot of benefits. However, the lecturer refutes the opinions in three aspects.
First of all, the lecturer asserts that the natural trees may
be survived survive in few amounts if suffer from climate changes and insects because of their genetic diversities. On the contrary, the genetically modified trees lack of genetic variety. Therefore, they might die away in some certain conditions.
Moreover, the lecturer argues that although cultivating genetically modified trees can bring economic benefits, it will cost much more than growing natural trees. For one thing, the farmers would pay more to buy the seeds of genetically modified trees. For another thing, it is cited in the laws that farmers should pay company money once they plant a genetically modified tree. As a result, considering the hinder costs,
they may not get more benefits than growing unmodified trees.这个好像不大准确啊Finally, the genetically modified trees may spread aggressively. They will compete with native trees for nutrient elements
in the like soil, sunlight, water and spaces. Consequently, genetically modifie
