今年初春,妈妈不知从哪要来一棵小树苗,栽种在院子里。不久,小树苗就长出了嫩绿的小叶子。
我问妈妈:“这是一棵什么树”
“无花果”
“无花果?它真的不开花就结果吗?”这个问题我一定要弄明白。
以后,我每隔一段时间就去看它,还给他浇水。它生长得很快,已经两米多高了,它那宽大的叶子就像我们的手掌。
今天我来到它面前,像是在搜寻着什么。突然,我眼前一亮,在它每一片宽大的'叶子的根部都有一个豆大的小青果,着难道就是它的果实?可我从来没见它开花呀?科学老师讲过植物生长一般要经过发芽、长叶、开花、结果几个过程,难道无花果真的不开花吗?
我迫不及待地打开电脑寻找问题的答案。终于找到了,《辞海》,上面说:我们吃的无花果,其实不是无花果树的果实,而只是花托膨大之后形成的肉球,而花和果实都包在这个肉球里面。肉球有许多小花,雄花和雌花上下分开,每个花都结出一个果实。所以说,无花果的营养成分很丰富。
为了进一步得到证实,我摘下一颗较大的无花果。用刀子将果实纵向切开,用放大镜仔细观察,尚未成熟的无花果露出了真面目——里面全是蛇一样的小花,样子十分可爱。原来无花果不是不开花,而是把花藏起来了,人们看不到而已。
得到了这个结论,我高兴地无法形容,为了将这一发现记录下来,我在其中的半个无花果上加上了天然色素苋菜汁,还拿来相机把它拍了下来。
啊!真想不到植物身上竟有这么多奥妙。我明白了,我们身边处处有科学,只要你细细地观察,就会有更多的发现。
The Role of Mobile Phone in People's Communication
The popularity of smartphones has exerted great influence on the way people communicate, so much so that an increasing number of individuals contend that face-to-face communication is being replaced by texts and images on the mobile phone.
There are more than one angle to consider this phenomenon. On one hand, it is pleasantly acknowledged that smartphones shorten the distance between families and friends. Even people from different sides of the globe can share pictures, feelings and thoughts through various types of apps on the phone, thus building a long-distance connection. On the other hand, as the picture warns us, too much smartphone addiction interferes with people's real-life communication. Statistics show that over 70 percent of face-to-face communication consists of facial expressions and body language, which is why people should stay away from mobile phones when they have the chance to actually talk and communicate with others.
In a word, mobile phones act as an appropriate platform where people can always stay in tough however long the distance is, but a wise man should know when to put down his phone.
