【题目】

Frogs are animals that can live not only in water but also on land. There are about 5,000 kinds of frogs on the earth. The earliest frogs lived about 190 million years ago and the frogs today still look the same. Here are some fun things that frogs.

Frogs are very good at jumping. The other large animals can’t eat them because they can jump very high. Using their big strong legs, most frogs can jump over 20 times their own length. It is like a person jumping over about 30.48meters. The Australian Rocket Frog can even jump over 2m, which is 50 times its body length(5.5cm). That might be the reason* why frogs are called the best jumpers on the earth.

Some frogs can be very big. The biggest kind of frog is the Goliath Frog in West Africa. Its body can be about 30cm long, about the size of a large cat. The Gold Frog and the Poison Frog are the smallest frogs in the world. They are less than 1cm long. The Poison Frog is very small, but it is not weak at all. It is dangerous. Any animal that eats it will die* very soon.
