是raise和rise吧:

The sun rises in the east.太阳从东边升起.
A good idea rose in my mind.他想出了一个好主意.
"raise"是及物规则动词,“举起,提高”.例:
He raised his voice to make himself heard.
为了听得更清楚些,他提高了嗓音.
The boy can raise the heavy stone.
那个男孩儿可以举起那块沉重的石头.
此外:这两个词除了提高、升高、抬起等意思外都各自还有其它的用法.例如:

招募:to raise an army
养育、栽培:to raise a family
提出(一个问题):to raise a question
建造、建立:to raise a memorial
发出(什么声响):ro raise a laugh,to raise the alarm
结束:to raise an embargo (解除禁运)
etc.
rise:

此外rise还有晋升;顶嘴;(风、风暴)转强等意思,这里就不一一举例了.
