TPO阅读部分是一个非常好的语料库，虽然里面的内容大都是科普类的，可能很难直接搬到我们的作文中，但是论证所需的词、短语、句式、乃至结构都是完全可以搬到我们的写作中来的，那么今天就和出国留学网的小编一起来看看TPO阅读有哪些经典语句适合做托福开头？
原文材料
These ideas remain controversial. Proponents point to features such as the terraced “beaches” shown in one image， which could conceivably have been left behind as a lake or ocean evaporated and the shoreline receded. But detractors maintain that the terraces could also have been created by geological activity， perhaps related to the geologic forces that depressed the Northern Hemisphere far below the level of the south， in which case they have nothing whatever to do with Martian water. [TPO 8-3-4]
这些观点仍然存在争议。支持者们指出照片里显示的台地“海滩”可能是由湖泊或者海洋蒸发干涸之后或者海退之后形成的。但是反对者认为这些台地也可能是由于地质活动造成的，也许与使得北半球比南半球地势更低的地质力有关。在这种情况下，它们就和火星水系没有任何关系。
参考句式
The issue whether [转述题目] remains controversial. Proponents point to the benefits of A such as a1 and a2. But detractors maintain that its advantages pale in comparison to the drawbacks.
X 这个问题依然存在争议。支持者提出 A 的好处，比如 a1， a2。然而，反对者坚持认为 A 的好处和坏处相比不值得一提。
这个经典的句式可以作为开头的争议部分。我们只需要在后面加一个表明立场的话就可以了。如果有兴趣前面也可以搞个背景。
参考练习
The issue whether governments should place economic development high on their list of priorities remains controversial. Proponents point to the benefits of a strong economy such as higher standard of living and lower unemployment rate. But detractors maintain that its advantages pale in comparison to the drawbacks.
政府是否应该把经济发展放到优先的位置上依旧是有争议的。支持者指出好的经济有很多好处比如更高的生活水准以及降低失业率。然而反驳者坚持认为这样做弊大于利。
