Integrated writing task

Topic discussed: Mima Mound

Notes

Reading: 

1, 因为Mima Mound的排列很整齐(were arranged in order),所以认为是人工的。说NA人可能是建造的人。

2, Earthquake: 这个结论是从另一个现象衍生出来的。另一个东西是因为震动形成的,所以估计Mima Mound也是。因为地震后土会松动,然后就形成了Mima mound.

3, Pocket gopher: gopher挖土堆起来的,用来build nest

Leture:

1,没有证据表明有人类活动和remains,所以不可能是人类活动造成的。

2Mima Mound所在的地方不是会发生地震的地方。另外,soil很难loose。如果想让soil loose的话,就需要很频繁的地震,但是好像没经历那么多地震。

3,现在也有gopher但是没有发现新的Mima Mound,所以不认为是gopher弄的。可能是别的什么东西,弄了Mima Mound然后就走了,剩下一个空的,然后gopher就来住了。

Essay question

A/D: Agriculture damages environment by producing more food.

【话题提示】

Agree

1, Excessive use of chemical inputs – ensure production of crops – fertility of lands – dried-up / not suitable for planting in the future / unlikely to recover 

2, Shorten lands for forestry or pasture – turn the use into cultivated lands – break the balance in eco-system: species / weather (precipitation & humidity)

Sample answer

Compared with the first half in the twentieth century, the world’s population has almost doubled. While figuring a solution to food shortage, many countries have adopted new methods to increase food production in order to meet the demands of growth in population. However, as far as I am concerned, to some extent, rise in food production is harmful to the environment.

 

First, in order to plant more crops, lands whose natures are forestry or pastures have been altered into the use of cultivated lands. We learn that forest and swamps have played an important role in maintaining ecological balance. Numerous flocks of birds and a variety of animals take them as their home. What’s more, swamps and rainforests largely determine an area’s precipitation and humidity, which affects the climate most. For instance, before a part of Amazon rainforest was explored by Brazil government or individuals, there were over two thousand species of animals living, which made a prominent contrast with the poor situation after a part of rainforest was changed into farmlands.

 

Moreover, some artificial inputs have to be used to ensure the production. Naturally, insects, disasters even climate changes all have negative effects on arigulture, then the use of chemical inputs becomes a must. Nevertheless, during the use of chemical inputs, it may weaken fertility of lands gradually and without people’s knowledge. As we all know, fertilizers and pesticides have strong acid which probably does harm to lands. The growth of crops may boom in one season, but the acid soil is not suitable for planting in the future. Chances are that the land is abandoned and then become dried-up. In a long run, the abuse of fertilizers and pesticides can make an irrecoverable damage to the ground.

 

To summarize, over-planting crops can lead to an irreversible situation by expanding farmlands and abusing chemical inputs. For the sake of nature and our living environment, I think adopting high technology is a wise choice in meeting the requirement of food for population growth.
