(A) 选择型阅读理解（每小题2分，共6分）
阅读短文，根据内容选择最佳答案。
The Arctic fox is a small animal that lives in the coldest places on Earth. It has thick white fur in winter to keep warm and hide from enemies. In summer, its fur turns brown or gray to match the rocks and soil. The Arctic fox can survive temperatures as low as -50°C.
The Arctic fox eats small animals like lemmings, birds, and fish. When food is hard to find, it follows polar bears to eat their leftovers. An Arctic fox can travel hundreds of kilometers to find food.
These foxes have short ears and short noses. This helps them keep body heat. Their feet have thick hair, too. This helps them walk on ice and snow without slipping.
Sadly, climate change is making the Arctic warmer. The snow melts earlier and comes later. This makes it harder for the Arctic fox to hide and find food. We need to do something to help these amazing animals.
( ) 1. Why does the Arctic fox's fur turn brown in summer
A. To keep warm. B. To match the environment. C. To find food.
( ) 2. How does the Arctic fox survive when food is hard to find
A. It eats plants. B. It follows polar bears for leftovers. C. It sleeps all winter.
( ) 3. What problem does the Arctic fox face now
A. It has no enemies. B. It eats too much. C. Climate change makes it harder to survive.
(B) 阅读简答题（每小题2分，共6分）
Plants are very important to all living things. Without plants, animals and humans could not live. Plants produce oxygen for us to breathe. They also provide food and shelter for many animals. Trees can make the air cleaner and cooler. Some plants are used to make medicine. For example, aspirin comes from the bark of a willow tree.
There are many kinds of plants. Some are big, like the giant redwood trees. They are the tallest trees in the world, reaching over 100 meters. Some are very small, like moss. Some plants live for a long time. The oldest tree in the world is about 5,000 years old!
Plants are amazing in many ways. They can grow in different places—in deserts, in oceans, and even on mountains. Some plants can eat insects, like the Venus flytrap. Others can close their leaves when you touch them.
We should take care of plants because they take care of us. Planting more trees and protecting forests are good ways to help our planet.
