flounder about

• • (在水、泥泞或雪地中)挣扎前进，笨拙地前进：

    Anna couldn't swim and was left floundering about in the deep end of the swimming-pool.

    安娜不会游泳，在游泳池的深水区挣扎着。

  • 错乱地说话；踌躇地表达；不知所措：

    Your question seems to have unnerved the speaker; he's been floundering about ever since you spoke.

    你的提问似乎打乱了演讲者的思想；你发言以后他说话就总出错。
