适量英语怎么说

适量英语的英文翻译是"a moderate amount"。这个词来源于拉丁语的"modus"，意思是"方式"或"程度"。例句如下：
I think a moderate amount of exercise is good for everyone.
He drinks a moderate amount of alcohol, but never to excess.
A moderate amount of sun exposure is healthy, but too much can be dangerous.
请注意，这里的"moderate"是一个形容词，意思是"适中的"，不能和动词搭配使用。例如，不能说"I moderate my alcohol intake"，应该说"I keep my alcohol intake moderate"或"I drink a moderate amount of alcohol"。
