Red squirrels used to be a common sight in British forests and countryside. But there are fewer than 140,000 red squirrels left now and most of them are in Scotland. However, grey squirrels (introduced from North America) are now so common that many people dislike them. They can be legally（合法的）trapped and destroyed.

   On first sight, the two types of squirrel are similar. They both have a long tail, which helps the squirrel to balance when jumping from tree to tree, and the same large eyes, small ears and powerful back legs. However, the grey squirrel has a clear physical advantage over the red. The red squirrel has a head-and-body length of 19 to 23 centimeters, a tail length of 15 to 20 centimeters and a body weight of 250 to 340 grams. Compared to this, the grey squirrel is a larger animal. The head and body measures between 23 and 30 centimeters long and the tail is between 19 and 25 centimeters long. Adult grey squirrels are heavier, weighing between 400 and 600 grams. This size allows them to store more fat and helps them to survive a hard winter, which would be fatal（致命的）to their  smaller cousins .

So why are red squirrels losing out in competition with grey squirrels? Size is one factor, but there are others. Red squirrels live high up in trees, while grey squirrels spend more of their time on the ground. This means any loss of forests greatly influences the red squirrel population. Another reason for the grey squirrel's success is its ability to use food provided by people. Like the fox, the grey squirrel can survive in towns and cities. The other problem for the red squirrel is disease. Both squirrels carry a certain virus. While this doesn't seem to attack grey squirrels, it is fatal to red squirrels.

    I have a lovely dog named Bobby. He looks pretty with short legs, big ears and short tail. He is my good friend and he is also easy to take care of. I walk him at least twice a day, feed him and spend time with him. He also gives his love to me in return.

    He is always there to lick me and lie on me. I like playing with him. I think he can tell when I am happy, sad, angry or troubled. Sometimes he can be noisy and run around the room. In a word, he is not only my dog, but also my friend.

    I love him. He can roll on the floor. He can play balls with me. He can look after my house when I am out. Bobby is very clever. But sometimes he isn't.

    One day Bobby runs away. He is out for three days. After he comes back, I tie him to a tree and give him some food. Bobby begins to eat. But then he stops. He sees a fox. The fox is looking at his food. Bobby barks and barks. He wants to catch the fox. But he can't. The fox runs round the tree. Bobby runs after the fox. So the rope goes ground the tree. Of course Bobby can't run. Quickly he eats up the food and runs away.

    How do you get to school? Do you walk or ride a bike? Do you go by bus or by train? For many students, it is easy to get to school. But for the students in one small village in China, it is difficult. There is a very big river between their school and the village. There is no bridge and the river runs too quickly for boats. So these students go on a ropeway to cross the river to school.

    Many of the students and villagers never leave the village. It is their dream to have a bridge. Can their dream come true?
