A. 英文表达 青蛙的生命周期

The life cycle of a frog

1.The Egg
Frogs lay their eggs in water or wet places. A floating clump of eggs is called frog spawn.
The large and slippery mass of eggs are too big to be eaten. This is nature's way of protecting them. But, the smaller clumps of eggs will be eaten by the creatures living near or in the pond.
The egg begins as a single cell. Several thousand are sometimes laid at once. It becomes surrounded by a jellylike covering, which protects the egg. The female may or may not stay with the eggs to take care of the young after she has laid them. The egg slowly develops. But, only a few develop into alts. Ducks, fish, insects, and other water creatures eat the eggs.

2.The Cell Splits
The single cell in the egg eventually splits into two. These two split making four cells, and so on. Eventually, there are many cells in the egg.

3.The Embryo
The mass of cells in the egg come to form an embryo. Organs and gills begin to form, and in the meantime, the embryo lives off of its internal yolk. This supplies it with nutrients for 21 days. Then . . .

4.The Tadpole
After its 21 day development period, the embryo leaves its jelly shell, and attaches itself to a weed in the water. This quickly becomes a tadpole, a baby frog. The tadpoles grow until they are big enough to break free into the water. This can take from 3 days to 3 weeks, depending on what kind of frog they will become. They eat very small plants that stick to larger plants in the water. These tiny plants are called algae. The tadpole has a long tail, and lives in the water. It is extremely vulnerable, and must rely on its camouflage to protect it.
The tadpole has a long tail, and lives in the water. It is extremely vulnerable, and must rely on its camouflage to protect it. The tadpoles also face danger by being eaten by other water animals. Sometimes the pond dries up. As a result the tadpoles die.

5.The Tadpole Begins To Change
After about five weeks, the tadpole begins to change. It starts to grow hind legs, which are soon followed with forelegs. Behind their heads bulges appear where their front legs are growing. Their tails become smaller. Lungs begin to develop, preparing the frog for its life on land. Now and then, they wiggle to the surface to breathe in air. The tail becomes larger and makes it now possible for the tadpole to swim around and catch food. They eat plants and decaying animal matter. Some tadpoles eat frogs eggs and other tadpoles.

Almost There . . .
Over time, the tadpole becomes even more froglike. They have shed their skin and lips. Its mouth widens, and it loses its horny jaws. The tail becomes much smaller, and the legs grow. The lungs are almost functioning at this point.

6.The Frog
Eleven weeks after the egg was laid, a fully developed frog with lungs, legs, and no tail emerges from the water. This frog will live mostly on land, with occasional swims. The tiny frogs begin to eat insects and worms. Eventually, it will find a mate. The way this is done varies depending on the species. The female lays the eggs, the male fertilizes them, and the whole process begins again.

回家后，我便把蝌蚪们倒进了我的小鱼缸里，我特地在盆底撒了一些泥土，还在水中水中放了一些水草。这会儿，小蝌蚪们肯定饿了，想了想，我就放了一些熟米和熟鸡蛋黄，看它们狼吞虎咽的吃着，我可高兴了！
好景不长，我养了没多久，由于我的粗心，小蝌蚪不但没有长出腿，反倒还死了几只，这令我伤心了好久，于是，我更加细心地照料剩下的蝌蚪。，在我的细心照料下，没过多久，小蝌蚪就长出了后腿，我更加有信心了！
皇天不负有心人，几周后，小蝌蚪的前腿也长出来了，我乐得合不拢嘴。慢慢地，它们的尾巴渐渐的缩短了，原来胖胖的身体也瘦了很多。一天，我早上起床后就迫不及待的去看看小蝌蚪，恩？怎么不见了？哦！原来它们长大了，不想在水里呆，都爬到缸壁上了呢！我就把水倒掉了，它们在缸底跳来跳去，真是可爱极了！
看着我亲手养的小青蛙，我心里无比的高兴，有一种强烈的成就感，这种感觉好极了！

D. 小蝌蚪变青蛙的英语作文

差不多一个月前，我们去公园玩，喜爸在一个池子里抓了几个蝌蚪。开始是不想抓的，青蛙是人类的好朋友，专吃害虫，保护庄稼，这咱从小就知道。可是又想，这就是一个公园，公园外方圆几里也早就没了庄稼地，公园里树木也不是很多，大多是草坪，青蛙也没啥要保护的。所以就抓了几个，主要目的是想让喜喜观察蝌蚪是怎么变成青蛙的。
回来后就后悔了，不知道怎么养埃上网查，说可以给面包屑和蛋黄，一天换一次水，换水时只能换一半。照着做，结果没几天，只有一个存活的了。这让我更加后悔了。一直不养小动物，就是因为如果它们死了我就特别难受。若干年前养过2只小鸡仔，1只死了后，另外一只不吃不喝叫了整整一天一夜后也死了。那叫声太凄惨了，现在想起来心还颤颤的。当时都不知道怎么处理它们，想把它们埋了，但正值冬天，地都冻了。最后是用雪把它们盖上的。
喜爸说我换水换的，蝌蚪们不适应，可是那水我是困了一天的了。不过再不敢换水了。就这样，还有人说我养得太干净，应该里面产生微生物才行。也不知道听谁的好了。所幸这只小蝌蚪长大了，变成青蛙了。其实到底是青蛙还是蟾蜍我也不清楚。听程妈说先出后腿的是青蛙，这只蝌蚪就是先出的后腿。可是这个说法被别人否了。爱啥啥吧，反正今天让喜爸给放了。既然长大了，就应该让它回归自然了。

E. 求一篇青蛙的生长过程英语作文！！

[扬子晚报网消息] 我经常在菜场或路边听到叫卖青蛙的吆喝声，看到一张张血淋淋的青蛙皮时，我心痛不已，严重时当场就吐了。我一直想不明白，人们知道青蛙是益虫，还有那么多的广告说要保护青蛙，《中华人民共和国野生动物保护法》也有保护青蛙的内容，可为什么还有那么多人捕捉、买卖青蛙呢？
青蛙是个捉虫能手：一只青蛙一年可捕食5-40万只蛀虫，还是稻飞虱、苍蝇、蚊子等害虫的克星。想想看如果人们捕捉一只青蛙，那么一年会有多少害虫得以逃生？“春捕一只蛙，秋少一担谷”说的就是这个道理。而且，如果一块田地养100只青蛙捕虫，要比农药的效果好得多。用农药的话，庄稼会被严重污染，人吃了会中毒生病，严重的还会导致死亡。由此可见，青蛙对人类和庄稼是多么重要。如果不保护青蛙的话，就会发生虫灾，稻飞虱迅速繁殖，庄稼也就颗粒无收。

青蛙还是个歌唱家：不管白天黑夜青蛙都能给人带来乐趣，青蛙一起叫，就像个大合唱，是段美妙的交响曲。

而现在人们就为了一点美味，捕杀、买卖青蛙，使得青蛙的数量越来越少，害虫的数量越来越多。人们应该好好反省。

大家一起来保护“地面除害专家”——青蛙吧！

F. 关于青蛙生长过程的英语作文

Frogs grow in five stages. First is the egg stage. The eggs are laid in wet places in slippery masses that hopefully don’ get slurped up by other hungry animals. The eggs are called a “frog spawn.” There the single cells divide for the next 20 days. And hopefully some survive to get to the next stage. The eggs feed on the little yolk sac inside.

At 21days, the eggs become tadpoles. They break out of their jelly egg homes and live in the weeds until they can swim. They eat algae and grow until their swimmy tails grow big enough to swim around.

After about five weeks the tadpole begins to grow legs, starting with the back legs, which is the third stage. In the fourth stage bulges grow behind their head and that’s where their front legs will grow. Their tails shrink. Their lungs grow so they can live on land. It’s almost a frog now.

The tadpole grows and grows to look more like a frog, shedding its lips and skin. Eleven weeks after it was one little cell, it is fully grown. Gone are the tail and the horny jaws. It can swim and live on land. It now can eat worms and bugs. When it grows to be a big frog it will find a mate and the whole process will begin again.
