- 试题详情及答案解析
- You need to ______ more. Don’t always be at the desk busy doing your _________.
| A．exercise, exercise | B．exercises, exercises |
| C．exercises, exercise | D．exercise, exercises |
- 答案：D
- 试题分析：句意：你需要多做锻炼。不要总是在书桌旁忙于做练习题。exercise意为“锻炼”时，是动词和不可数名词；意为“练习”时，是可数名词。第一空表示做锻炼，need to do sth“需要做某事”，故此处用动词原形exercise。第二空表示做练习，故用可数名词的复数形式exercises。故选D。
考点：考查名词的用法。
