①. 副词修饰动词时，凡是可以放在句首、句中或句末。如：Usually I do my homework in the evening. (句首) 凡是我晚上做家庭功课。 I often get up at six. (句中) 我常在6点起床。Please speak slowly. (句末) 请逐步说。
留意：频度副词凡是置于系动词、情态动词、助动词之后，实义动词之前。譬喻： Mary is always late for the meeting.?玛丽开会总是迟到。We must always remember our friends.我们必需紧记我们的伴侣。?
I have never been to London. 我从未去过伦敦。My mother often does morning exercises in the morning.我妈妈常常在早上做早操。?
②. 副词修饰形容词或副词时，凡是放在形容词或副词的前面，但也有破例。如：These flowers are quite beautiful. (在形容词前) 这些花相当大度。 He works very hard. (在副词前)他事情很尽力。 She is old enough to go to school. (在形容词后)她已到了上学的年数。
A.副词very 可以修饰形容词，但不能修饰动词。 譬喻：(错) I very like English. (对) I like English very much.
B.副词enough应放在所修饰的形容词、副词或动词的后头，形容词enough放在名词前后都可。譬喻：The boy is old enough to go to school.这个男孩到上学的年数了。I know him well enough. 我很是相识他。
He didn't get up early enough to catch the early bus. 他起床不足早，没有遇上早班车。
quite/rather a good player=a very good player.一个相当不错的球员。
③. 按一般法则，假如有几个时间状语，单元大的应放在单元小的后头。如：The film will begin at seven o'clock this evening. 影戏今晚7点开演。 I was born at two o'clock on the morning of May15.
④. 按一般法则, 既有所在状语又有时间状语时，所在状语应放在时间状语之前。如：We had a meeting in the classroom yesterday afternoon. 我们昨天下午在讲堂开了一个会。 He watched TV at home last night. 他昨晚在家看电视。
