英语六级攻克阅读关键句193. After all, a little healthy worrying is o

193. After all, a little healthy worrying is okay if it leads to constructive action—like having a doctor look at that weird spot on your back.

译文　毕竟，稍稍为健康担忧未尝不可，如果这点担忧能够让人们采取有益的行动——比如说让医生检查一下你背上那个奇怪的斑点。

点睛　本句的主干是...a little healthy worrying is okay...。其中if引导条件状语从句；破折号后面的内容是对于action的举例说明。

worrying多作形容词，意为“焦虑的”，而在本句中为名词，意为“担忧”。weird意为“怪异的”。如：

He looks like nothing on earth in those weird clothes. 他穿着奇装异服难看极了。

考点归纳　constructive和destructive形式相近，含义却截然相反：

constructive意为“建设性的；有帮助的”。如：

The government is encouraging all parties to play a constructive role in the reform process. 政府鼓励所有的政党在改革过程中发挥建设性的作用。

destructive意为“破坏性的；有害的”。如：

A locust is a kind of destructive insect. 蝗虫是一种害虫。
