Question

【题目】Tom's parents are pleased because Tom can study than usual.

A.more carefullyB.more carefulC.much more careful

Answer 1

【答案】A

【解析】

句意：汤姆的父母很高兴，因为汤姆能比平时更认真地学习。

考查副词的比较级。more carefully更认真地；more careful更认真；much more careful更认真的，根据所给空前面的study可知，应该用副词修饰动词，由than usual可知，应该用副词的比较级形式，故选A。
