我想問一下關於比較的英文句子

A is more expensive than B. B is more expensive than C. A is the most expensive.

The capacity of A is more than that of B. The capacity of B is more than that of C. The capacity of A is the greatest/most.

John runs faster that Peter. Peter runs faster than Tim. John runs the fastest.

Mr Wong is taller than Mr Chan and Mr Chan is taller than Mr Lee. Mr Wong is the tallest. Mr Lee is the shortest.

例子一
比較3件products，a貴過b，b又貴過c，a就係最貴啦
a is more expensive than b while is more expensive than c, so a is the most expensive.
一個形容詞有三個或以上既音節(ex-pen-sive), 就會加more, the most.

例子二
比較大小
a is larger than b while b is larger than c, so c is the smallest and a is the largest.

一個或二個音節既形容詞, 就會在形容詞既尾加 -er, -est.

其實市面有好多小四既英文補充練習有好充足既例子同解釋, 買一本做下會好有幫助.
