2017年托福写作范文精选集(1)
阅读主要观点提取：
海龟(sea turtles)数量急剧下降，已经濒临灭绝。有几种方法可以阻止海龟数量继续下降。
第一种方法是修建一种金属围栏(metal fences)来保护海龟蛋不被捕食者吃掉。由于海龟蛋经常被捕食者吃掉，所以在海龟蛋的周围修建铁丝栅栏可以保护他们。
第二种方法是禁止使用塑料袋。海龟常常因为将塑料袋当作水母(jellyfish)吃掉而死亡。所以只要倡导使用纸袋而不是塑料袋便可以保护海龟。
第三种方法是制定一个法律让渔民捕鱼的时候使用海龟逃离器(turtle excluders)。渔民之前捕鱼的时候所用的渔网会迫使海龟窒息而死。如果渔民使用海龟逃离器可以避免海龟游到渔网中，以减少海龟的死亡率。

阅读中的每种方法都有缺陷(weakness)。
第一，修建金属围栏会对海龟以后的生存和繁殖产生不利影响。在海龟蛋旁边修建了金属围栏，会干扰磁场(distort magnetic field)。幼小的海龟就不能发展对它们生存至关重要的磁场感来航行。
第二，禁用塑料袋也不能有效的解决问题。因为海洋里已经有数千亿甚至数万亿的塑料袋。这些塑料袋需要数百年分解(decompose)，即使它们分解了还是会对海龟有害。
第三，渔民不会愿意使用海龟逃离器。因为使用海龟逃离器会减少他们的捕鱼量，因而减少他们的收入。所以，即使有法律要求他们使用，他们也会偷偷拿掉海龟逃离器，当回到岸边的时候再安装上去。
托福综合写作满分范文：
The professor discusses that each suggestion to help reverse the decline in sea turtle population put forward by the writer has a weakness.
First, the writer says that building metal fences around turtle eggs could protect them from predators. But the professor makes the point that turtles may have troubles in surviving and reproducing later if they are protected by wire fences. The young sea turtles might not develop the magnetic sense properly If wire fences are around them. It is because metal fences would distort the magnetic field.
Second, as for the banning of the plastic bags, the professor states that it would not solve the problem. Because of the wide use of the plastic bags for a long time, there are already billions if not trillions of plastic bags in the ocean, and it takes hundreds of years to decompose these plastic bags. Even bags can slowly break up into smaller pieces, they remain harmful to sea turtles.
Finally, the professor holds the opinion that the benefit of using turtle excluders is very limit which is contrary to the reading material. The simple reason is that the fishers are reluctant to use excluders. By using these turtle excluders, the fisher’ income would decline because the number of fish they catch would reduce. So they would not use it the whole time. They may remove the excluders once they are not seen and then put it back when they return to the shore.
