comparison點用

1單音節+2音節用er/est.>2音節用more/the most例:單音cheap(er/est),(more/the most) 3音expansive
2唔正常變法,例如good→better→best,bad→worse→worst,唔多,靠記
3比較(compare)數量(quantity)always(成日,10之9/10)→often(經常,10之7/8)→ usually(通常,10之5/6)→sometimes(有時,10之3/4)→seldom(少,10之1/2)→never(永不,10之0)
4a=b.a is as beautiful(原型)as b→ab一樣咁靚
5靠理解佢意思,佢會畀提示...唔緊張就得,唔難,冇捷徑

If the exam has that part,then use:-
(1)comparative adj;superative adj=Grammar has the form of an adv. that express of sth in 2 to 3 sounds are by degrees slowly and gradually to be answered with.
(2)superative adj and Irregular comp=for 3 sounds to without er--est---eg good,(better),best ,always go into 3 sounds express more in amount or quality="Better"is comparative of"good" and "more difficult" is comparative of "difficult".
(3)When the three topics are comparaing,quantities,as+adj+as,it usually comes after the following briefly eg:- as big as.as busy as,as good as,as mean as,as much as, as sticky as, as wetted as,...which are written in the Dictionary with your looking after them in case they show up.

　　　　　　　　　多謝你既發問,希望幫到你~

1-2個音既字 用+er/+est 黎顯示邊個較好/最好。
She is taller than me. (用er 同than 表示較好)
She is the tallest student in my class. (用the +est 表示最好)3個音以上既字 用more/the most 表示較好/最好。
She is more beautiful you. (用more 表示較好)
She is the most beautiful girl in my class.(用the most表示最好)有d字係冇er同埋est,就要記!(例如:good,better,best/ bad,worse,worst )
Miss Chan is a good teacher.
but Miss Wong is better. (較好)
And the best teacher is Miss Lam.(最好)

而as+adj+as就好似比喻咁~ 頭一個AS後放形容詞
而後一個AS就好似中文既 (與...一樣)
例子:
The school is as large as Disney Land.
My dad is as busy as a bee.
My English is not as good as my classmates.
She is as dumb as a post.
She is as naughty as a monkey. (佢好頑皮,與猴子一樣)
as busy as a bee = 非常忙碌(好似BEE咁勤力)
as dumb as a post = 非常笨 (好似木頭咁)Comparing quantities可以睇下呢個網址~

2段：She is more beautiful than you.(用more..than表示較好)
3段：You are my best friend.(用best表示最好)
4段：as soon as possible.(愈快愈好)
