托福阅读修辞目的题是阅读考试中比较常见的一种题型，tpo则是托福阅读备考最权威的材料，所以托福小编综合二者，为大家集中整理了tpo阅读中考察的修辞目的题及其对应的解析，供大家参考使用。本文带来的是TPO25-2的修辞目的题，一起来看看吧。
TPO25-2 The Decline of Venetian Shipping
Paragraph 5:The conventional explanation for the loss of Venetian dominance in trade is establishment of the Portuguese direct sea route to the East, replacing the overland Silk Road from the Black sea and the highly profitable Indian Ocean-caravan-eastern Mediterranean route to Venice. The Portuguese Vasco da Gama’s Voyage around southern Africa to India took place at the end of the fifteenth century, and by 1502 the trans- Abrabian caravan route had been cut off by political unrest.
10. Why does the author mention “Vasco da Gama’ Voyage around southern Africa to India” in the passage?
○ to indicate how the Portuguese came to challenge Venetian dominance of trade with the East
○ to explain why political troubles resulted in the closing of the usual routes to India
○ to prove that Venetians could not sail round ships as efficiently as sailors from other countries did
○ to show that Venetian reliance on round ships rather than galleys proved to be weakness
解析：修辞目的题，先读highlight 句子，但发现全句只是个例子，于是看上一句，说对于威尼 斯人失去贸易上统治地位的传统解释是葡萄牙人建立了direct sea route，所以正确答案是A，葡萄牙人搅和了威尼斯人的统治地位。B的 political trouble，C和D的 round ships 原文定位句中均未提及。
[5] 对威尼斯人失去贸易主导权的传统解释是，葡萄牙人建立的直接通往东方的海上航线替代了起自黑海的陆上丝绸之路以及通往威尼斯的高利润的印度洋—东地中海陆上商路。在15世纪末期，葡萄牙的瓦斯科•达•伽马实现了环绕南非到达印度的航行;而在1502年，通往阿拉伯国家的商路因政治动荡被切断。
以上就是托福阅读TPO25-2中的修辞目的题及其解析，大家可以在备考的时候参考复习，希望能够帮助大家的考前准备。最后前程百利祝大家都能取得理想的托福考试成绩。
