<例句>
I saw it clear.
我看得很清楚。
<语法分析>
在这个局子里，副词clear与clearly意思相同，在句子里的位置相同，二者可以互换。有些同源副词词义各异，所以不能互换。如果词义基本相同，但在句子里所处的位置不同，则二者不可以互换。两个同一性质的副词状语在一起时，单位大的一般要放在单位小的后面。大多数副词没有倾向性，但有些副词却含有积极意义或消极意义，这取决于它所在的语言环境。
<触类旁通>
(1)He is running round in the field.
他在场上兜圈子。
语法分析：round为“完全，绝对”，roundly为“严厉地”虽为同源副词，但意义不同。
(2)She doesn't talk loudly or laugh loudly in public.
她不在公共场所大声谈笑。
语法分析：loudly意为“大声地”和loud的意思相同，所以可用loud在相同位置替换loudly。
(3)He firmly supports us.
他坚定地支持我们。
语法分析：有些副词如与形容词筒形，位置在动词后，多在句末;如是ly结尾，多放在动词前面，所以在句中firm不可替换firmly。
(4)I'm going to start at nine tomorrow.
我明天九点出发。
语法分析：两个同一性质的副词状语在一起时，单位大的一般要放在单位小的后面。
(5)The weather is rather cold today.
今天天气特别冷。
语法分析：rather和completely多与表示消极意义的词连用。
(6)She is perfectly satisfied with it.
她对此非常满意。
语法分析：entirely,fairly和perfectly多与表示积极意义的词连用。
