青蛙对人类的好处

青蛙对人类的好处 最近，正好是夏天最热的时候，正是青蛙繁殖的好季节。可是，时常有人吆喝着卖青蛙。一只只活泼可爱的青蛙死于非命，令我痛心疾首。眼看着它们倍受摧残，自己却无能为力那是多么的无奈呀。 青蛙是动物世界中出色的“歌唱家”，它那“呱呱”的叫声，时常在我耳边萦绕。它们开的是多动人的音乐会呀～ 我爱青蛙，不仅仅因为它的叫声，更因为它有天才般杰出的捉虫本领。所以，它是庄稼的“保护神”。 青蛙的舌头两边分叉，又细又长。它只要把长长的舌头一伸，虫子就成为了腹中的美食。你别看它穿着一身绿色的外衣，在小虫子的眼里，简直令它们望而生畏。 可是，那些贪图小利的人呢,竟然忘恩负义，把青蛙一只只的残害而死。哎，他们怎么不想想，捉掉一只青蛙，到底放掉了多少的害虫呀～这可是大自然妈妈所不允许的，也是我所不想看到的。 大家想一想:如果没有青蛙的付出，我们怎能吃到那一颗颗饱满的米粒呢, 青蛙是人类的朋友，我们一定要好好爱护它们呀。 没有青蛙,农民伯伯辛辛苦苦种下的庄稼就会遭受害虫. 有人做过统计,一只青蛙平均一昼夜能捕食70多只害虫,一个月约2000只. 如果按青蛙每年活动期六至八个月计算,可以消灭各种害虫15000只左右. ships of 72 and a half the Harbour, like room Tao Yuan.

Stationed in Wujiang's 全国各地青蛙千千万万,帮助人类消灭着无数害虫. 青蛙是我们一致认同的益虫,但是仍旧有几个人去伤害它们. 青青蛙是两栖类动物，最原始的青蛙在三叠纪早期开始进化。现今最早有跳跃动作的青蛙出现在侏罗纪。因为青蛙是以昆虫和其它无脊椎动物为主食，因此必须栖息于水边。青蛙捕食大量田间害虫，是对人类有益的动物。它不单单是害虫的天敌，丰收的卫士，那熟悉而又悦耳的蛙鸣，其实就如同是大自然永远弹奏不完的美妙音乐，是一首恬静而又和谐的田野之歌。“稻花香里说丰年，听取蛙声一片”，有蛙的叫声农民就有播种的希望，有蛙声就有收获的喜悦和欢乐～ 从前的都市郊区和乡村都有一片片宽阔的水塘，那里是蛙类生息的乐园。然而几乎是一夜之间却被都市的蔓延所吞噬，一些残存的青蛙成了真正的井底之蛙，它们虽然有幸生存下来却不幸失去了田野，失去了禾苗，失去了活动的天地和自由，甚至只有等到夜深人静的时候，才敢法生生地发出几声鸣叫，轻轻地，缓缓地，似乎怕惊扰了都市瑰丽的梦幻，又似在一声声地呼唤着远离它们的同伴。但它们越来越多的同伴也正在城市的另一些角落更为绝望地哀鸣～一双双贪婪的手把它们从田野捉来，又被一双双麻木的手将它们买去，它们还来不及瞧一眼陌生的都市，就生生地成了家家案俎上的肉食～相比于那一双双或贪婪或麻木的大手，它们的反抗显得是那样的软弱和乏力，它们只有发出一声声凄惨绝望的哀鸣～ ships of 72 and a half the Harbour, like room Tao Yuan.

Stationed in Wujiang's 青蛙是捉害虫的能手，平时青蛙不轻易动弹，当虫子飞过，它就会向上一窜，舌头一钩，又落在地上，小虫子就成了青蛙的美餐了～电视上的科教片介绍说:“一只青蛙一年之内最少可以消灭一万只害虫呢!” 我要大声告诉你们:青蛙是人类的好朋友，我们一定要爱护它们哟! 青蛙是人类的朋友作文三:青蛙是人类的朋友(319字) 我发现有些人经常捕杀青蛙，许多青蛙死于非命，成为人们餐桌上的美食，我感到非常痛心。 青蛙的用处可大了，当然，对人类的贡献也很大。它可以吃庄稼里的害虫，使庄稼长得更茂盛。它那大大的眼睛可以看清四面八方的虫子，它那灵活的舌头，害虫碰到了就别想逃走。还有那健壮的双腿，可以跳得很高。 人们喜欢吃青蛙肉，觉得味道很不错。我想告诉大家:由于人们不想害虫吃庄稼，就经常喷洒农药。而青蛙以吃害虫为主，害虫长期吃的庄稼被喷了农药，身上就会有毒，而青蛙吃了害虫，也有一些毒。所以人吃了青蛙肉也会有一点毒～为了身体健康，希望大家以后不要吃青蛙肉了。 青蛙是人类的朋友，希望大家今后不再捕杀青蛙，也不吃青蛙肉，让青蛙留在田里保护庄稼。让生态永远平衡，让世界更加美好。 青蛙是人类的朋友作文四:青蛙---人类的朋友(294字) ships of 72 and a half the Harbour, like room Tao Yuan.

Stationed in Wujiang's 我发现有许多小朋友喜欢捉青蛙，我感到非常难过。因为青蛙是我们人类的朋友。 青蛙是田野的守护神，它捕食大量田间害虫，是对人类有益的动物。据说，一只青蛙一小时可以吃一百二十多只害虫，一年能吃一万多只害虫呢，而其中一些害虫是向我们人类传播疾病的，例如苍蝇、蚊子，如果我们大量的捕捉青蛙，就会造成青蛙越来越少，害虫越来越多了。青蛙不单单是害虫的天敌，还是丰收的卫士，那熟悉而又悦耳的蛙鸣，其实就如同是大自然永远弹奏不完的美妙音乐，是一首恬静而又和谐的田野之歌。“稻花香里说丰年，听取蛙声一片”，有蛙的叫声农民就有播种的希望，有蛙声就有收获的喜悦和欢乐。 保护青蛙，人人有责～保护青蛙，就等于保护自己～ 青蛙是人类的朋友作文五:青蛙是人类的朋友(290字) 青蛙是我们人类最好的朋友，青蛙保护我们的庄稼吃对农业有害的害虫，所以才是我们的好朋友。 告诉你们，青蛙是我们庄稼的保护神，它每天他专吃如蛾、蚊、蝗虫、蝼蛄、椿象、蝇类及稻飞虱等农业害虫为主要食物，告诉你们一只青蛙一天最少得吃五十只害虫，多得也得吃上两百只害虫，一年(按照三百六十五天算)大约也得吃一两千多只害虫，看看这是多大的功劳啊～就连生活在水里的小蝌蚪也可以每天吃100只孑孓，青蛙是著名的游泳健将，它们可以消灭水里的好多只害虫。青蛙的眼睛很大可以看清四面八方的虫子可以和蜻蜓媲美，再加上长长的舌头就ships of 72 and a half the Harbour, like room Tao Yuan.
