表对比或转折的并列连词

英语中表示意思转折或对比的并列连词主要有but和yet两个。

并列连词 but 意为“但”“但是”“却”。如：

I appreciate your problem, but I don’t think I can help you. 我理解你的困难, 但却爱莫能助。

This beach is good for swimming but bad for surfing. 这片海滩宜於游泳而不适合作冲浪运动。

并列连词 yet 也表示“但是”“却”，与并列连词 but 用法相似，有时可换。如：

It is strange yet true. 这很奇怪，却是真实的。

He was poor, yet happy. 他很穷，可是很快乐。
