同学们你们看到这个题目一定会想;手表除了让我们知道几时几分几秒以外,它就没什么作用了。同学们若你们真的这样想的话,那你就想错了。我想你们一定很想知道错的原因。那么,下面我就告诉你们吧。 手表除了告诉我们时间外,手表还可以辩别方向。比如;我们在野外迷了路或者在一个陌生的地方迷了路,可以看一看你手上的手表或看一看家长手上的手表就不会迷路了。
具体方法是;将当时的时间除以2,再把所得的商在手表上对应的数字对准太阳,表盘上12所指的方向就是北方,其他方向就可推算出。如;上午10时,10除以2得商数是5,将表盘上的5对准太阳,12所指的方向就是北方。但,应注意的是,所用的时间要按24小时记时法,如;下午5时,就应按17时计算。同学们,你们可千万要记住呀。 同学们,这下你们明白错的原因了吧。
