2017年托福寫作范文精選集(1)
閱讀主要觀點(diǎn)提?。?BR> 海龜(sea turtles)數(shù)量急劇下降，已經(jīng)瀕臨滅絕。有幾種方法可以阻止海龜數(shù)量繼續(xù)下降。
第一種方法是修建一種金屬圍欄(metal fences)來保護(hù)海龜?shù)安槐徊妒痴叱缘簟Ｓ捎诤｝數(shù)敖?jīng)常被捕食者吃掉，所以在海龜?shù)暗闹車藿ㄨF絲柵欄可以保護(hù)他們。
第二種方法是禁止使用塑料袋。海龜常常因?yàn)閷⑺芰洗?dāng)作水母(jellyfish)吃掉而死亡。所以只要倡導(dǎo)使用紙袋而不是塑料袋便可以保護(hù)海龜。
第三種方法是制定一個(gè)法律讓漁民捕魚的時(shí)候使用海龜逃離器(turtle excluders)。漁民之前捕魚的時(shí)候所用的漁網(wǎng)會(huì)迫使海龜窒息而死。如果漁民使用海龜逃離器可以避免海龜游到漁網(wǎng)中，以減少海龜?shù)乃劳雎省?BR> 聽力主要觀點(diǎn)提取：
閱讀中的每種方法都有缺陷(weakness)。
第一，修建金屬圍欄會(huì)對海龜以后的生存和繁殖產(chǎn)生不利影響。在海龜?shù)芭赃呅藿私饘賴鷻?，?huì)干擾磁場(distort magnetic field)。幼小的海龜就不能發(fā)展對它們生存至關(guān)重要的磁場感來航行。
第二，禁用塑料袋也不能有效的解決問題。因?yàn)楹Ｑ罄镆呀?jīng)有數(shù)千億甚至數(shù)萬億的塑料袋。這些塑料袋需要數(shù)百年分解(decompose)，即使它們分解了還是會(huì)對海龜有害。
第三，漁民不會(huì)愿意使用海龜逃離器。因?yàn)槭褂煤｝斕与x器會(huì)減少他們的捕魚量，因而減少他們的收入。所以，即使有法律要求他們使用，他們也會(huì)偷偷拿掉海龜逃離器，當(dāng)回到岸邊的時(shí)候再安裝上去。
托福綜合寫作滿分范文：
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.
