Scientists are always looking for these unknown (未知的) kinds. In 2019, a group of researchers (研究人员) led by a university professor named Austin found a new animal. They were in Papua, an island region, studying many kinds of life. One night, the researchers were listening to frog sounds. Suddenly, they heard some really strange sounds. At first, they didn’t know where the unique sounds came from. After a while, they found the sounds were from the ground. They started to look carefully among the leaves. They thought they would find an insect. But what they found surprised them. It was a very small frog-only 7 mm long! Austin said, “This frog’s sound doesn’t sound like a frog. It sounds like an insect.” The frog they found was the smallest frog in the world. Researchers think frogs and insects are very important. They help keep our earth clean and we can also use them to make new medicine (药). Researchers around the world work hard to find new plants and animals every day. But their work is getting more and more difficult. This is because the forests where these animals live are getting smaller. The discovery (发现) of this small frog tells us that our earth has many amazing secrets(秘密)waiting to be found. Protecting nature means protecting these chances. 20．How many kinds of plants and animals do we know now? A．About 1.8 million. B．About 8 million.
