環(huán)境類

【題目解析】

題目大意：越來越多的人從農(nóng)村搬遷到大城市。該趨勢給環(huán)境帶來的優(yōu)點(diǎn)更多還是缺點(diǎn)更多。

這個(gè)題目有一個(gè)陷阱，即“環(huán)境”，所以考生需要寫“城市化對環(huán)境的好壞”，而非其他方面的優(yōu)缺點(diǎn)。

這個(gè)題目屬于“優(yōu)劣勢”，考生既要寫出優(yōu)點(diǎn)，也要寫出缺點(diǎn)。我們可以按照“outweigh”題型的方式處理這個(gè)題目；如果“優(yōu)大于劣”可以寫“2個(gè)優(yōu)點(diǎn)1個(gè)缺點(diǎn)”；如果“劣大于優(yōu)”可以寫“2個(gè)缺點(diǎn)和1一個(gè)缺點(diǎn)”。筆者的觀點(diǎn)是“劣大于優(yōu)”。

【寫作思路】

Para 1=題目改寫+個(gè)人觀點(diǎn)

Para 2=缺點(diǎn)1（空氣污染嚴(yán)重）

Para 3=缺點(diǎn)2（生物多樣性受到威脅）

Para 4=優(yōu)點(diǎn)1（環(huán)境保護(hù)的科技得到發(fā)展）

Para 5=總結(jié)段

【參考范文】

Nowadays,a growing proportion of rural residents are leaving their homes for large metropolises.Personally,I am inclined to the view that the drawbacks of this trend to the environment prevail over the benefits.

The key disadvantage is the deteriorating air quality in major cities.With more people pouring into and settling down in these places,the likelihood of them purchasing private vehicles that rely heavily on fossil fuels will be high.However,the consumption of these energy resources may well lead to excessive emissions of toxic fumes,including sulphur dioxide and consequently,air pollution will become an issue.

Another downside is that biodiversity will be threatened.The rapid expansion of cities occupies a great amount of land for the construction of multifarious types of infrastructure,such as airports,roads,shopping malls,and residential blocks,but a wide range of species of flora and fauna will become extinct during the process because their habitats are damaged.As a result,there will be fewer types of animals and plants on the Earth.

However,the advantages of more rural people relocating to megacities over the environment are worth considering,one of which is that the innovation of technology regarding environmental protection will be encouraged.Having realised the detrimental effects of human behaviour on the environment,scientists are endeavouring to experiment with environmentally friendly ways humans can develop.This can tackle the current challenges people are encountering and benefit future generations as well.

In conclusion,I agree that there are more negative outcomes than positive ones in terms of the environment if more and more individuals from the countryside migrate to metropolitan areas.Although inventing new technologies can be the solution to environmental issues,in my opinion,serious air pollution and the damage to biodiversity in cities are still major concerns at the moment.Therefore,experts should accelerate the progress of technology development to simultaneously ensure human advancement and environmental conservation.
