I think the dance by Group A is better____

问题单项选择题

I think the dance by Group A is better______that by Group B.
[A] than [B] as [C] and

答案

参考答案：A

解析：[精析] 本题考查的是比较级的用法。than是连词，常用于形容词或副词的比较级之后。引导表示比较关系的从句或短语；as用于比较级时，需用形容词或副词原级；and表示并列连接，不能用于引导比较级结构。根据题中better，故A项正确。
[知识拓展] 英语中有三种基本比较结构：1．not so/as+形容词或副词原级+as，如：The car runs as：fast as that one．2．形容词或副词比较级+than，如：The street is narrower than that one．3．形容词/副词最高级+比较范围，如：John is the brightest of the three boys．
