我們朗思教育老師給同學(xué)們帶來2020年7月18日托福考試寫作機經(jīng)，希望對同學(xué)們后期的備考和復(fù)習(xí)提供一些幫助，如果同學(xué)們還想了解更多關(guān)于考試學(xué)習(xí)經(jīng)驗，可以隨時關(guān)注我們網(wǎng)站的其它內(nèi)容，也可以直接咨詢我們線上的老師進行答疑。
有一種蚊子傳播一種疾病，科學(xué)家發(fā)明了一種基因改良過的蚊子和這種蚊子交配，導(dǎo)致后代有缺陷，減少這種蚊子的popularity，可以預(yù)防疾病
有些人不同意，原因:
(1)蚊子數(shù)量下降，可能導(dǎo)致其他帶有同樣病毒的蚊子數(shù)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(dǎo)致環(huán)境問題，可能會對其他物種產(chǎn)生影響，例子是種改良過的菜，但是菜周圍的蝴蝶數(shù)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.
