常見錯誤
✗
This bag isn’t as heavy than that one.
✓
This bag isn’t as heavy as that one.
否定原級比較用 not as/so...as，不能用 than。
✗
She runs as quick as me.
✓
She runs as quickly as I do.
動作要用副詞 quick→quickly；正式寫作後面常用主格並加助動詞 do。
✗
I have as much books as you.
✓
I have as many books as you.
可數名詞複數要用 many，不可用 much。
✗
He is so tall as his dad.
✓
He is as tall as his dad.
肯定句比較同等程度用 as...as；so...as 多見於否定或疑問。
✗
This T-shirt is as more cheap as that one.
✓
This T-shirt is as cheap as that one.
原級比較不用比較級標記（-er/more）。
✗
She is as tall as me.
✓
She is as tall as I am.
考試與正式文寫作傾向用主格並補出被省略的 be 動詞（I am）。口語雖常用 me，但不建議於測驗。
✗
We don’t have so many homework as them.
✓
We don’t have as much homework as they do.
homework 為不可數名詞，用 much；代名詞主格接 do 代表前詞動詞。
