跳河、江、湖、海……为什么会死?

How many people have jumped into the river?
people 加s?一般不会吧.

QuYuan walked towards a bank of MiLo laying his long hair down to the full length .His face was pale like a lief .A fisherman saw him and asked:"aren't you the Prime Minister "san lv"?Why do you come here.Why your condition is so bad?"Qu said:"The people in the whole world are turbidy like polluted water.But I am so clean.Besides,They are drunk ,but I am awake .Because of this reason ,I got expulsion as the punishment given by the king.The fisherman said:"If someone is a great man ,he will stand by the whole world people supporting their opinion.even it isn't truth.Now that ,the people in the whole world are turbidy like poplluted

告诉别人,我就会在这跳的,我是跳河死的.要不没有人看见,大家还不知道自己是怎样死的呢.跳到河里谁知道漂哪去了.

根据物理学公式：s=1/2 at方,您下降的时间大约是1秒,根据公式V=at,您接触水面时的速度是10m/S,很据动量公式：FT=MV,设您接触水面0.5秒钟,您受到的冲击力大约是您20倍的体重,估计在这一瞬间您勉强可以承受.假设您的体重是130斤,就是75公斤,根据能量公式：FS=Mgh,水需要对您做7500焦耳的功,水对您的浮力和您的体重差不多,按750牛顿算,您会在水中下降大约5M左右（扣除您在水中时重力对您所做的功）,加上空气阻力和水的阻力,4M深的水够了.
这个是理论的计算值,误差0.5M左右,具体数值和您的体型和入水姿势和水的粘稠度有关,如果真的遇到这种情况,千万别趴着入水,高空入水最好的姿势是把身体弯成135度角,脚先接触水,紧接着屁股坐进水里面,这样对身体的总体冲击最小.
说得够明白的了.

清代乾隆年间,翰林院有一位叫做纪昀的学士.他学识渊博,能言善辩,机智过人.一个风和日丽的上午,乾隆皇帝想开个玩笑为难纪昀,便问道：“纪昀,忠孝二字怎么解释?”纪昀回答：“君要臣死,臣不得不死,这是忠,父要子亡,子不得不亡,这是孝.”乾隆立即说：“我已君的身份命你现在去死!”“这……臣遵旨!”“你打算怎么去死?”“跳河.”“好,好吧!”乾隆知道纪昀不会真的去跳河,只想看看他到底有什么办法免去一死.纪昀走后,乾隆便迈着方步,吟起了古诗,一首古诗还没吟完,纪昀就跑了回来.乾隆问道：“纪昀,你怎么没死?”纪昀说：“臣碰到了屈原,他不让臣死.”“这话怎么讲?”“我到了河边,正要往下跳时,屈原从水里走了出来,他拍着我的肩膀说：‘纪昀,你这样就不对了,!想当年楚王是昏君,我不得不死,如今皇上还算圣明,你应该回去问问皇上是不是昏君,如果皇上说是的,你再死也不晚啊!’”乾隆听了纪昀的话说：“好一个如簧之舌.行了!行了!我算服了.”
