半个句型要记牢

by courtesy of (蒙……的好意，蒙……提供)

Tip:

courtesy的意思是"礼貌，殷勤，好意如 He wrote back to her out of courtesy. (他出于礼貌给她写了一封回信)，而 by courtesy of为固定短语，表示"蒙……的好意，蒙……提供"如 This is a radio programme presented by courtesy of a soap company. (这是一档由一家肥皂公司提供的广播节目)。如果不了解这一短语，还可以用 introduce这个相对常见的单词，如be introduced by...表示"由……介绍" introduce还可以用recommend或pass on替换。
