12．約翰（John）比班上其他所有人都擅長數(shù)學． （ be good at）
John is better at math than the other students in the class．．

Answer 1

分析 John is better at math than the other students in the class．

解答 答案：John is better at math than the other students in the class．表達的是客觀事實用一般現(xiàn)在時，表示兩者之間的比較用比較級，be good at表示擅長于…，good 的比較級是better，故John is better at math than 主語John是三單，故is，the other students in the class班上其他所有人．故答案是John is better at math than the other students in the class．

點評 be good at 后面要接名詞、動名詞或名詞/動名詞短語，
請看例句：
John is good at swimming and basketball
It is important that we try to be good at everything we do
I have a shrill voice．I'll never be good at singing．
