注意：频度副词通常置于系动词、情态动词、助动词之后，实义动词之前。例如： Mary is always late for the meeting.?玛丽开会老是迟到。We must always remember our friends.我们必须牢记我们的朋友。?
I have never been to London. 我从未去过伦敦。My mother often does morning exercises in the morning.我妈妈经常在早上做早操。?

注意：
A.副词very 可以修饰形容词，但不能修饰动词。 例如：(错) I very like English. (对) I like English very much.
