從不同的角度描述同一事物，例如，自學(xué)teach oneself;遠程教育 distanct、learning。再如：

In his 1776 work The Wealth of Nations，Scottish economist Adam Smilh proposed that specialization in production leads to increased output. 蘇格蘭經(jīng)濟學(xué)家亞當?斯密在其1776年所著的《國富論》中認為，專業(yè)化生產(chǎn)會引起產(chǎn)出增加。

這里，把“生產(chǎn)的專業(yè)化”轉(zhuǎn)變?yōu)椤皩I(yè)化生產(chǎn)”，把“增加的產(chǎn)出”轉(zhuǎn)變?yōu)椤爱a(chǎn)出增加”。

FDA publishes GUIDANCE TO INDUSTRY for the first time. This guidance, "Procedures for the Appraisal of the Toxicity of Chemicals in Food, ”came to be known as the "black book." FDA首次發(fā)布《產(chǎn)業(yè)指導(dǎo)》。該指導(dǎo)題目為 “食品中化學(xué)制劑毒性的評估程序”，人們習(xí)慣稱之為“黑皮書”。

這里把被動轉(zhuǎn)變?yōu)橹鲃印?/p>

“正話反說，反話正說”也屬于視角變換：

In 1954, MILLER PESTICIDE AMENDMENT spells out procedures for setting safety limits for pesticide residues on raw agricultural commodities. 1954 年，《米勒殺蟲劑修正案》詳細規(guī)定了制定未加工農(nóng)產(chǎn)品殺蟲劑殘留標準的程序。

The bill was defeated, but during the next 25 years more than 100 food and drug bills were introduced in Congress. 雖然議案未獲通過，但在隨后的25年中，有多個食品與藥物法案被提交到國會。
