Question

--- Yes . He usually prefers _________ at home to playing outside .

A．the most hard-working , studying	B．more hard-working , to study
C．the most hard-working , to study	D．more hard-working , studying

Answer 1

A

试题分析：根据in my class可知，本句应该是最高级，根据one of +形容词的最高级+名词复数的用法，应该排除BD；根据prefer doing to doing“喜欢干某事，而不喜欢某事”，是固定用法。所以本题选A。
点评：对于第一个空，学生还是比较容易做的，而对于第二个空，许多学生可能会犯错误，可能会受到prefer to do rather than do“喜欢干某事，而不喜欢某事”的影响，实际上，此处的动名词相当于名词，如prefer apples to bananas。
