有一種蚊子傳播一種疾病，科學家發明了一種基因改良過的蚊子和這種蚊子交配，導致后代有缺陷，減少這種蚊子的popularity，可以預防疾病
有些人不同意，原因:
(1)蚊子數量下降，可能導致其他帶有同樣病毒的蚊子數量上升，其中可能包括一些有些可能有更厲害的病毒蚊子；
(2)如果基因改良的蚊子咬人的話，傳到人的身上，對人體無益；
(3)放出這些蚊子可能導致環境問題，可能會對其他物種產生影響，例子是種改良過的菜，但是菜周圍的蝴蝶數量減半；
The content of the reading and the listening is totally different to each other in whether the new methods can reduce the population of mosquitoes. To begin with, the author indicates the method significantly diminishes the number of mosquitoes on the targeted species. Yet the speaker says that with the reduction of the targeted mosquito number, other species of mosquito can increase greatly. Those mosquitoes in the increasing can even be more fatal to humans.
In the second place, in the passage, the engineered mosquito will carry the gene to affect their next generation in the expected outcomes. However, from the lecturer, this might not be a good idea since we do not know if the genes will go wrong and creates new disease. Besides, what if humans are bitten by those mosquitoes, the consequences might be deadly, yet the reading further points out that the mosquito bites are all the same.
Thirdly, the method is really environmental friendly because it uses no toxic chemicals. Yet the speaker does not think so, indicating that DNA altered mosquitoes pose potential threats to hurt other species. Recently news revealed the butterfly population was diminished greatly in fifty percent because of the nearby herbicide usage.
