raise 与 rise

动词 raise 与 rise 分别对应及物与不及物的形式。不过，我发现前者通常被误用为不及物动词。¹ 以下例句将说明两个单词各自的正确用法。

1. The level of the oceans is rising more rapidly than previously reported.
2. Awareness of the importance of frequent hand washing has risen in recent years.
3. The sun rises in the east.
4. We are considering raising the minimum passing score.
5. At each step, the position of the bar was raised by 3 cm.
6. If you wish to speak, please raise your hand.

¹出于某些原因，相反的误用情形相当罕见。
