求解选择题的思路和方法多种多样,如根据题设条件,按照顺向思维的过程,由相关知识求解出正确答案,或由定义、定理、定律等知识对语言叙述逐条进行正误判断,从而选出正确答案等等。同时也应该注意到。对于某些选择题,我们可以凭借已有的经验、知识,采用直觉思维方式,把答案中不可能出现的情况立即排除掉,直接把剩余的唯一答案选作正确答案。下面举几个例子予以说明。[例1]把自由下落物体的总位移分成相等的三段,则由上到下顺次经过这三段位移所需的时间之比是:

Choose the correct answer, and so on. It should also be noted at the same time. For certain multiple-choice questions, we can rely on existing experience, knowledge, and intuitive thinking to immediately eliminate the impossible situation in the answer, and directly select the only remaining answer as the correct answer. Here are a few examples to illustrate. [Example 1] To divide the total displacement of a free-falling object into three equal segments, the ratio of the time required to pass through these three segments from top to bottom is:
