问题 His mind was______on one thing: how to break record in the game.

选项 A、concentrated
B、described
C、observed
D、depended

答案A

解析 本题考查动词(短语)的被动语态。concentrate意为“集中注意力于”,可与on搭配构成固定短语concentrate sth.on sth.,符合题意。describe意为“描述”,用作及物动词,其后不接介词;observe意为“观察,发现”,用作及物动词,其后不接介词;depend常与介词on搭配,意为“依赖”,不用于被动语态。
