   Arctic fox(北极狐) is a kind of small fox that lives in the Arctic. It grows about 50 centimeters long, not including its tail, 30 centimeters tall and weighs from 3 to 7 kilos.
   The Arctic foxes are white or blue in color. The white ones are white in winter, but grey-brown in summer. The blue ones are blue-grey all year round. The Arctic foxes have long, thick hair that is called fur. And the long fur covers their whole bodies, including both their cat eyes and rabbit feet, to keep them warm in the low temperature in the Arctic.
   The Arctic foxes feed mainly on birds, birds' eggs and other small animals. Teamwork is the way they look for food, and they don't like to do that alone.
   Baby Arctic foxes are very lovely. They don't open their eyes until a week after their birth. For the first half of the year, their parents offer them food. They begin to look for food on their own when they are about six months old. The next year they can live alone.
   Today, the number of the Arctic foxes is becoming smaller and smaller, because people kill them for their fur to make beautiful coats for money. Something must be done to protect the Arctic foxes.

(1)、Not all the Arctic foxes change their colors in different seasons.

(2)、The Arctic foxes have rabbit eyes and cat feet.

(3)、Baby Arctic foxes are born with their eyes open.

(4)、 Birds, birds' eggs and other small animals are the main food for the Arctic foxes.

(5)、 According to the passage, there are more Arctic foxes now.

There is little rain in desert. Because deserts are so dry, they have no "quilt" to help stop the soil from going away. As a result, they may get very hot during the day with the sun shining, but don't hold the heat overnight. Many deserts can quickly get cold once the sun goes down. Some deserts can reach temperatures of over 100 degrees F during the day and then drop below freezing (32 degrees F) during the night.

The largest hot and dry desert in the world is the Sahara Desert in Northern Africa. The Sahara is a sandy desert with great sand hills. It covers over 3 million square miles of Africa. Other large deserts include the Arabian Desert in the Middle East, the Gobi Desert in Northern China and Mongolia, and Kalahari Desert in Africa.

Animals that live in the desert are also used to needing little water. Many get all the water they need from the food they eat. Other animals keep water that they can use later. The camel stores up fat in its hump while other animals keep something they need in their tails.

Only certain types of plants can live in the terrible environment of the desert. You won't see a lot of tall trees in the desert. Most plants have a way to keep water in their leaves, or trunks so they can live a long time without water.

Now deserts cover around 20% of the world's land, but they are growing. This is called desertification and is caused by different reasons including human activities. The Sahara Desert is growing larger and larger each year. What should we do with it ?


阅读下面短文, 从每题所给的A、B、C、D四个选项中选出最佳选项。

Some people have sensitive (敏感的) feet or skin. Others may have a hard time laughing at their own mistakes. Perhaps you live with someone like this. But can you imagine living with a sensitive plant?

 Now, imagine that your hand is a green plant stem(茎) and each of your fingers is a leaf. Use your other hand to touch your leaf fingers. One at a time, close each leaf finger. until you have made a fist. Quickly drop your hand down to your leg. Wait a little while, and then slowly bring your hand back to its original(原来的) position.

 It's just this kind of behavior that has made the sensitive plant get its name. Brush your fingers gently across the leaves of the sensitive plant, and the leaves at once fold up(合拢) like tiny green fingers. The stems drop down as if ready to fall off the plant. About ten minutes later, the leaves open again, and the stems rise again! Sensitive plants are easy to grow inside your house. They simply need to get plenty of water and sunlight. But touching the plant too often can cause the plant to lose its leaves. A sensitive plant that loses many of its leaves may become unhealthy.

 Imagine the fun you can have: introducing a friend to your plant! Have your friend stand close to the plant to tell it jokes. Touch your plant with a finger, and watch your friend's reaction when the plant seems to drop down slowly to say"no". Be sure to tell your friend the true cause of the plant's behavior later, though. You don't want your friend to become overly sensitive about his jokes!
