个风和日丽的下午,我正在洗手,洗着,洗着,竞不知不觉地玩起水来。这时,我的脑海中忽然闪现出一个念头,如果我折一条小纸船放在水里,它会不会沉下去呢? One sunny afternoon, I was washing my hands, washing, washing, competing unconsciously to play with water. At this time, a thought suddenly flashed in my mind, if I fold a small paper boat and put it in the water, will it sink? 说干就干,于是我立刻兴致勃勃地折了一条纸船放在水里,纸船竞然没有沉下去。我转念一想:“如果给它增加一些阻力,那会沉下去吗?想到这,我立即行动起来,首先我对着小船用嘴使劲地吹风,并拼命地拍打水面,最后还用手按住小船往水里压,小船沉下去但又马上浮上来了。不论怎样,它始终浮在水面上。霎时间,我的心里涌出了无数个问号,急忙跑去问妈妈:“为什么小船不会沉下去?我还对着它吹风,起浪,甚至还用手去按它,可它还是不会沉下去?” Said to do, so I immediately happily folded a paper boat and put it in the water, but the paper boat did not sink. I turned to think: "if you add some resistance to it, will it sink?"? Thinking of this, I immediately started to act. First, I blew hard at the boat with my mouth, and beat the water desperately. Finally, I pressed the boat into the water with my hand, and the boat sank but immediately came up. Anyway, it always floats on the water. All of a sudden, my heart gushed out countless question marks, hurriedly ran to ask my mother, "why can't the boat sink?"? I still blow and wave at it, and even press it with my hand, but it will not sink? " |
