On today's composition class, the teacher gave us each a medlar, let us be put into water to look what can produce. Does “ put medlar in water? ” , I think strangely, do this return “ what can you produce? ”
今天的作文课上，老师给了我们每人一把枸杞，让我们放进水里看看会发生什么。“把枸杞放在水里？”，我奇怪地想，“这还能发生些什么啊？”
I look at the medlar of a bead before, the size like its fingernail, of black Gong Heigong, feel a little hard, resemble coarse bark, resemble the face of a piece of old grandma again, wrinkled.
我看着面前的一粒粒枸杞，它指甲盖般大小，黑红黑红的，摸起来有些硬，像粗糙的树皮，又像一张老奶奶的脸，皱巴巴的。
I cast them into boiled water, a lot of medlar float float on surface ah float, also 9 shake heavy of surplus of leisurely of shake from side to side, surplus in water, but very fast also float come up, caught up with team of medlar greater part.
我把它们投进开水里，许多枸杞浮在水面上漂啊漂，也有一两粒在水中晃晃悠悠、浮浮沉沉，但也很快浮了上来，跟上了枸杞大部队。
I observed a long time, medlar people motionless float is on surface, seem to enjoying hot spring in carefree ground. How can “ change to also be done not have a bit? ” this problem is wandering ceaselessly in my head. I take a medlar, hold, the small seed of that Huang Huang skip came out, flashy, the feeling of a hot heat is passed to my finger tip, each is small hubble-bubble was risked come out, be like a string of beauty, glittering and translucent full marks / the pearl necklace that get rid of appears. Medlar shrivelled, soft. I dropped a hand at once, throw water in.
我观察了半天，枸杞们一动不动地浮在水面上，好像在悠闲地享受着温泉。“怎么会一点儿变化也没有呢？”这个问题在我脑中不断徘徊着。我拿起一粒枸杞，一捏，那黄黄的小籽儿就蹦出来了，一瞬间，一股热热的感觉传到我的指尖上，一个个小泡泡冒了出来，好像一串美丽的、晶莹满分/剔透的珍珠项链。枸杞瘪了，软了。我连忙撒了手，扔入水里。
Strange thing happening, after the medlar after be being held falls into water, before resembling in that way on the surface on float, sank however instead benthic. I felt puzzled, in former days ” of “ natant champion, how be held dropped benthic to go down? when medlar is being held, satiate does water abdomen become heavy? Be still water changed? Each is new idea is flush in my head. Is this after all why?
奇怪的事发生了，被捏后的枸杞落入水中后，没有像之前那样浮上水面上了，反而是沉到了水底。我纳闷了，昔日的“游泳冠军”，怎么被捏了捏就掉到水底下去了呢？难道枸杞在被捏的时候，吃饱了水肚子变重了？还是水变了呢？一个个新想法在我的脑中泛滥。这到底是为什么呢？
The teacher saw our doubt, laughing to tell us: “ classmates, actually ah, medlar can float rises, it is the air in recumbent cutcha medlar, the density that compares water because of air is small, so medlar resembles natant loop same float rose. And air was done not have in the medlar after be being held, it sinks naturally. ”“ , such before! ” I can't help plainting scientific force is boundless.
老师看出了我们的疑惑，笑着告诉我们：“同学们，其实啊，枸杞之所以能浮起来，是靠着晒干的枸杞里的空气，因为空气比水的密度小，所以枸杞就像游泳圈一样浮起来了。而被捏后的枸杞里没了空气，它就自然而然地沉下去了。”“哦，原来如此啊！”我不禁感叹科学的力量是无穷的。
