i want to ask some question....(about grammar)

當我們在形容物件，利用副詞(adverb) + ly去造句：
1. She speak english clearly and properly .
2. Tom runs quickly .
句子 1 的adverb是形容她說的english
句子 2 的 adverb是形TOM 跑
不是全部adverb都加ly (well , good )

當我們比較(TWO)物件，利用er去造句：
1. Mary is taller than Betty .
2. Linda is the tallest .
句子 1 的是 2人比較 .
句子 2 的是 3 人比較，Linda最高 .
不是全部都加er
Betty is the most beautiful in our class .
May is more beautiful than Cherry .

er 系比 comparison
ly 系形容

i am prettier than XXX ( i am pretty)
i am taller than XXX (i am tall)

the car is newly painted
the car was newer before (comparing now and then)

the card was beautifully made (張卡做得好靚)
the card is beautiful (張卡好靚)
