保護(hù)蜻蜓英語(yǔ)日記
我這幾天發(fā)現(xiàn)有許多的小朋友非常喜歡捕捉蜻蜓，使得很多很多的蜻蜓死于非命，我感到特別特別痛心。
I've found that many children like to catch dragonflies very much these days， which makes many dragonflies die。 I feel very sad。
蜻蜓是大自然中非常出色的'“除害專家”。在飛行時(shí)時(shí)速可達(dá) 100 公里，蜻蜓的眼睛大大的，，從來(lái)沒(méi)有害蟲(chóng)能逃脫蜻蜓銳利的眼睛，蜻蜓吃蒼蠅、蚊子，還有些小飛蛾，就連蜻蜓的幼蟲(chóng)生活在水里的時(shí)候以蚊子的幼蟲(chóng)—孑孓為食，在兩年的稚蟲(chóng)期里大約可以吃掉 4，000 只孑孓，到了成蟲(chóng)期一小時(shí)能吃掉 20 只蒼蠅， 800 只蚊子，蚊子會(huì)通過(guò)吸血，能傳播痢疾、乙型腦炎、登革熱和絲蟲(chóng)病等多種疾病 蒼蠅也是一樣，讓人不得安生，而且蜻蜓只是自帶的細(xì)菌 有了新細(xì)菌也不會(huì)傳染到人，所以說(shuō)蜻蜓對(duì)于我們來(lái)說(shuō)是多么的重要啊，蜻蜓還是人類的不離之友。
Dragonflies are very good "experts in killing pests" in nature。 When flying， the speed can reach 100 kilometers per hour。 The eyes of dragonflies are big。 No pests can escape the sharp eyes of dragonflies。 Dragonflies eat flies， mosquitoes， and some small moths。 Even when the larvae of dragonflies live in the water， they eat the larvae of mosquitoes — larvae。 During the two—year larval period， they can eat about 4， 000 larvae can eat 20 flies and 800 mosquitoes in an hour in the adult stage。 Mosquitoes can spread dysentery， encephalitis B， dengue fever， filariasis and other diseases by sucking blood。 The same is true of flies。 Dragonflies are just bacteria New bacteria will not infect people， so dragonflies are very important to us。 Dragonflies are also inseparable friends of human beings。
大家一起來(lái)保護(hù)我們的“除害專家————蜻蜓”吧！
Let's protect our "exterminator" —— Dragonfly！
