extend的手到底可以伸多长？
在《中式英语之鉴》看到一个例句是这样写的：
The United States needs to extend trade privileges to China permanently.
美国应该永久地为中国提供贸易特权。
其中extend是一个我们很常见的词。
从释义上看，它可以看作是enlarge，prolong，expand，stretch的集合。
例句中，extend trade privileges to China 按字面翻译，“将贸易特权扩展到中国”，我们也可以调整一下将它译成“为中国提供贸易特权”。
其实extend的用法和搭配都很丰富，我们可以留心一下哦～
