五、阅读理解
Nowadays, hundreds of thousands of animals around the world are facing different kinds of threats(威胁). They are in danger and in need of protection and conservation efforts.
Among these threatened animals, one that needs special mention is the koala. It is close to being an endangered animal. Interestingly, the koala is partly to blame(承担责任) for its decline. Koalas are too stubborn(固执的) for their own food!
When you were younger, were you a picky eater? Did your parents have to ask you to eat things that were good for you? Hopefully you listened to what they taught you and ate your dinner.
Koalas are picky eaters. They live in tall eucalyptus(桉树) trees. Koalas eat the leaves of those trees. Since there are over 600 different kinds of eucalyptus trees, koalas should have no trouble finding food. But koalas are picky! They only want certain eucalyptus tree leaves to eat. Out of the 600 kinds of trees, koalas will only eat the leaves of about 120 kinds of eucalyptus trees. Some are even pickier than that. The koalas of a specific area will only eat about four or five kinds of eucalyptus leaves. They would rather starve than eat the other kinds. Now that's stubborn!
At present, koalas also face many threats in the wild, from deforestation, drought, disease, habitat loss to climate change. For example, the 2019—2020 Australian bushfire season was one of the most deadly wildfires ever experienced, leading to the big loss of the tree-hugging koalas. However, the biggest problem for koalas now is that the brush(灌木丛) land in Australia is being cut down. Towns and cities are pushing farther into the brush. Since many koalas live there, they are losing their tree homes and the tree leaves that feed them.
Today, scientists think that there are fewer than 100,000 koalas left in the wild. Luckily, governments have made laws to protect them. If we don't act now, koalas on the east coast of Australia could disappear forever by 2050.
