Question

12．约翰（John）比班上其他所有人都擅长数学． （ 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．表达的是客观事实用一般现在时，表示两者之间的比较用比较级，be good at表示擅长于…，good 的比较级是better，故John is better at math than 主语John是三单，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．

点评 be good at 后面要接名词、动名词或名词/动名词短语，
请看例句：
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．
