保护蜻蜓英语日记

  我这几天发现有许多的小朋友非常喜欢捕捉蜻蜓,使得很多很多的蜻蜓死于非命,我感到特别特别痛心。

保护蜻蜓英语日记

  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'“除害专家”。在飞行时时速可达 100 公里,蜻蜓的眼睛大大的,,从来没有害虫能逃脱蜻蜓锐利的眼睛,蜻蜓吃苍蝇、蚊子,还有些小飞蛾,就连蜻蜓的幼虫生活在水里的时候以蚊子的幼虫—孑孓为食,在两年的稚虫期里大约可以吃掉 4,000 只孑孓,到了成虫期一小时能吃掉 20 只苍蝇, 800 只蚊子,蚊子会通过吸血,能传播痢疾、乙型脑炎、登革热和丝虫病等多种疾病 苍蝇也是一样,让人不得安生,而且蜻蜓只是自带的细菌 有了新细菌也不会传染到人,所以说蜻蜓对于我们来说是多么的重要啊,蜻蜓还是人类的不离之友。

  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。

  大家一起来保护我们的“除害专家————蜻蜓”吧!

  Let's protect our "exterminator" —— Dragonfly!
