托福寫作范文:棕櫚樹擴大種植
閱讀主要觀點提取:
總論點:棕櫚油(palm oil)可以應用到很多領域,近些年得到廣泛關注。專家認為要進一步擴大棕櫚樹的生長。
分論點一:種植棕櫚樹可以保護森林。因為棕櫚樹的產油量高于其它農作物,所以需要的土地相對較少,可以避免過度砍伐森林。
分論點二:將棕櫚油用作生物柴油(biodiesel)可以減少碳排放。碳排放降低了,對緩解全球氣候變化有積極的影響。
分論點三:生產棕櫚油可以緩解貧困。大部分棕櫚樹都是由低收入的農民種植的。并且,棕櫚樹相比于其他農作物利潤更高,所以可以提高這部分農民的生活水平。
聽力主要觀點提取:
總論點:種植棕櫚樹有消極的影響不應該擴大規模。
分論點一:種植棕櫚樹會進一步加劇森林的砍伐。因為,棕櫚油可以用在很多方面,如食品和化妝品(cosmetics)。因此,全球對棕櫚油的需求在不斷提升。這會促使農民砍伐更多森林來種植棕櫚樹。一個國家,每分鐘就有7000平方米的森林被砍伐來生長棕櫚樹。
分論點二:燃燒棕櫚油制成的生物柴油會增加碳排放。汽車使用生物柴油會產生較少的碳排放。但是,生產棕櫚樹的過程卻會產生更多碳排放。因為,農民需要先將土地上的植被燒掉來種植棕櫚樹,在燒的過程中,會燃燒一種泥煤(peat)。泥煤中含有大量的碳,所以會產生更多的碳排放。
分論點三:從長期來看,農民的收入不會提高。一開始,是農民生產棕櫚樹。到后來,大規模的公司會開始種植棕櫚樹并控制利潤。
托福綜合寫作新題滿分范文:
The reading argues that palm oil production has positive effects and is supposed to be expanded. On the contrary, the listening believes that there are serious negative effects and the expansion of palm oil production is not a good idea.
First, the passage states that palm tree farming helps preserve forests. However, the lecture denies the idea by saying that the increasing demand for palm trees because of its widely use in food and cosmetics products forces farmers to clear more forests to grow more palm trees. It results in increasing deforestation around the world.
In addition, the professor says that though it is true that using biodiesel made from palm oil can produce fewer emissions. Growing palm trees, however, generates a lot more carbon emissions, which contradicts the idea proposed in the reading. In order to gain the land for palm tree farming, farmers clear the land by burning plants including peat which stores huge amounts of carbon. This burning process will send out large quantities of carbon emissions.
Finally, the reading holds that producing palm oil helps poor small-scale farmers. The professor points out that they will not control the farms too long. In the long run, the large-scale companies will obtain lands and thus control most profits. Consequently, small-scale farmers will not get much return. (218words)
