On Sunday afternoon, I play basketball in basketball field. Passed a little while, the day becomes cloudy heavy, resembling is to was about to rain, then I am driven toward the home rapidly. On the road, I discover a flock of dragonfly to fly very lowly. I can't help interrogative: At ordinary times dragonfly flies very high, the dragonfly before why raining is low fly?
星期天下午，我在篮球场打篮球。过了一会，天变得阴沉沉的，像是快要下雨了，于是我赶紧往家赶。在路上，我发现有一群蜻蜓飞得很低。我不禁疑惑：平时蜻蜓都飞得很高，为什么下雨前蜻蜓会低飞呢？
The dragonfly before I am taking “ why to rain will be low this problem goes flying ” seek father and mother, but father says however: This problem yourself goes to “ seek the solution. Then my decision goes to ” the bookshelf has a look at the result that I have to want in the book then. But the book in my general bookshelf broke up again, did not find the solution namely. I am crestfallen, extremely depressed.
我带着“为什么下雨前蜻蜓会低飞”这个问题去找父母，可爸爸却说：“这个问题你自己去寻找答案吧。”于是我决定去书架那看一看书里有没有我要的答案。可我将书架里的书翻了又翻，就是没有找到答案。我垂头丧气，沮丧极了。
When just when I want,abandoning, father walked over suddenly, to my say: “ baby, check malcontent branch / arrive not to lose heart, still have other measure probably, for instance can high-tech of have the aid of will search the answer. ” listened this word, I remembered Baidu immediately, cry greatly: “ is right, can check Baidu, how cannot I think of. ” I wanted a mobile phone to father immediately, begin to get online search the answer.
正当我要放弃时，爸爸突然走了过来，对我说道：“宝贝，查不满分/到不要灰心，或许还有其他办法，比如可以借助高科技来查找答案啊。”听了这话，我立刻想起了百度，大喊道：“对，可以查百度呀，我怎么没想到。”我立刻向爸爸要了手机，开始上网查找答案。
Eventually, I found dragonfly low the reason that fly. The raindrop when original dragonfly rains to prevent, hail and thunder harm him, reduced flight height so. The atmospheric pressure before raining at the same time is low, air humidity is big, major insect can reduce the height of the flight, and dragonfly to prey these gnat, also fly very lowly as them. At this moment my suddenly be enlightened.
终于，我找到了蜻蜓低飞的原因。原来蜻蜓为了防止下雨时雨点、冰雹和雷电伤害到自己，所以就降低了飞行高度。同时下雨前气压低，空气湿度大，大部分昆虫会降低飞行的高度，而蜻蜓为了捕食这些小昆虫，也就随着它们飞得很低了。这时我恍然大悟。
I just know nature is medium now accumulate containing the knowledge with interesting so much.
