Scientists think there are between eight and fourteen million kinds of plants and animals，but we only know about 1.8 million now. They are slowly finding new kinds all the time，and that's good news for us.
In 2009， a group of scientists went to the rainforest to look for new kinds of animals.They had to walk silently and looked really carefully. They found a frog(青蛙) that is smaller than the end of your smallest finger! They found another frog，too.That looks like it is made of glass.The scientists also found seven new kinds of grasshoppers(蚱蜢).Some of them are very beautiful.
Scientists tell us that frogs and insects(昆虫) are very
important. They help to keep our environment clean. We can also use them to make new medicines. Researchers all over the world are working very hard to find new kinds of plants and animals. But their jobs are getting harder，because forests where these animals live are quickly disappearing，and so are the animals.
