先開始我不懂該怎樣飼養蝌蚪，就用自來水養它們，但是過了兩天就發現有些蝌蚪出現了翻肚子的情況，陸陸續續地又有幾只蝌蚪變成這樣。於是我請教了媽媽，媽媽告訴我不要用自來水飼養蝌蚪，應該去一些有水藻的池塘里撈一些水回來飼養，也去池塘里挖一些長在池塘邊上的水藻放在水裡，因為那些水裡面有微生物和水藻，水藻可以進行光合作用，可以為蝌蚪提供氧氣，微生物則可以給蝌蚪提供食物。

我想到了寶姐姐家裡有一個魚缸，裡面養了兩條魚，水是微微泛青的，於是我按媽媽說的去做在裡面撈了一些水回去給蝌蚪換上，第二天蝌蚪都不再翻肚子。過了一個星期左右，有兩只蝌蚪長了兩條後腿，先開始我還以為是它的排泄物，後來慢慢的長長了，我才知道那是它的後腳 。我發現有隻蝌蚪的肚子上面一些的地方長了兩只小腳，是它的前腳！但是因為時間有限，我不能把照片發上來，雖然它長了前腳，但是尾巴還是挺長的，可能還要一段時間才能慢慢變短。

我原來是挺怕蝌蚪的，可是養了這么久也覺得蝌蚪還是很可愛的。畢竟它們是青蛙的幼體，它們長大之後都是要吃害蟲的。
I don't know how to start feeding tadpoles, raising them with tap water, but after two days they found some tadpoles through the stomach, one after another and a few tadpole like this. So I asked my mother, my mother told me not to raise tadpoles with tap water, should go to some algae pond fishing some water back to the pond feeding, digging some long in the pond on the algae in the water, because the water there is bacteria and algae, algae can carry out photosynthesis, can provide oxygen as a tadpole, microorganisms can provide food for tadpoles.
I think there is an aquarium Bao sister home, which raised two fish, the water is slightly green, so I as mom said to do some fishing in water back to second days for tadpoles, tadpoles are no longer turned belly. After about a week, there are two tadpoles long two legs, at first I thought it is excrement, then slowly long, I only know that it is the foot. I found a tadpole belly above some place two feet long, it is! But because of the limited time, I can't take photos, although it is a long tail or front, but for a long time, it may take some time to get shorter.
I was very afraid of the original tadpoles, but raised for so long also think that tadpoles are still very cute. After all, they are the larvae of the frog, they grow up to eat the insects.

⑷ 英文表達 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.

⑸ 英語作文青蛙的叫聲

Frogs grow in five stages. First is the egg stage. The eggs are laid in wet places in slippery masses that hopefully don』t get slurped up by other hungry animals. The eggs are called a 「 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.
