“国考题目引发热议：罚球起跳成难点，足篮举重跳水常识挑战考生”

12月1日讯，2025年度国考公共科目正式开考。在行测考试中，一道与体育知识相关的题目引起了广泛关注，并迅速登上微博热搜。

根据考生回忆，这道试题的内容如下：

请选出以下错误的一项：

• A. NBA罚球可以双脚离地
• B. 举重比赛中，运动员试举需要三盏白灯都亮
• C. 跳水运动员得分与姿势和翻转周数有关
• D. 足球比赛一般90分钟

在这道试题中，大部分球迷认为“违背常识”的是A选项。实际上，根据规定，在篮球罚球时确实允许双脚离地。以下为NBA官网对这一问题的解释：

问题：罚球时，可以起跳吗？

答案：

No regulations state that a player cannot jump during free throw shooting. However, as players age, it is less common to see them jumping at the line.

这里有两个主要因素:

1. 投篮过程中，运动员不应踩到或越过罚球线，而跳跃通常会产生向前动力，从而导致违规。
2. A consistent routine is important for every shot; bending the knees without jumping helps stabilize the body and limits unnecessary movement which aids in consistency.
.

Please note that not jumping can be challenging for younger athletes due to their size and strength.

If you observe NBA players when they take free throws, although they often do not jump, they fully extend their legs and lower bodies while shooting.
