There are many kinds of tigers all over the world, and the largest tiger is Northeast tiger, also
called Siberian tiger. The largest Northeast tiger can be over two meters long and weigh more than
200 kilos. Some Northeast tigers live in the northeast of China, like Heilongjiang Province andJilin Province，because there are many forests and mountains in these areas. The tigers usually
like living there. In the forests and mountains, there are fewer people living there. Therefore, few
people get out and come in. So the tigers are very free. They can live a quiet life. They can run
after each other, catch and eat some animals, like rabbits.
The Northeast tigers are different from the ordinary tigers. For example, the Northeast tigers can
not only swim very well, but also climb the trees. The Northeast tigers’ hearing is great, too.

The long trunk of an elephant is a wonderful example of skill. The neck of fourfooted animals
is usually long, to have them reach their food without difficulty, but the elephant has a short neck,
to make him more easily support the weight of his huge head and heavy teeth. His long trunk lets
him get his food easily.
The trunk of an elephant is to him what the neck is to other animals. It is also a nose to him,for at the end of it there is an empty place like a cup, and in the bottom of the cup there are two
holes, and the animal smells and breathes through them. It is an arm and a hand too, so that it has
been said that the elephant carries his nose in his hand, and it might also have been said that he
breathes by his hand.
At the end of the trunk, there is a strange part, about five inches long, which forms a finger.
With this finger the animal can pick up the smallest piece of money from the ground, and he has
been taught to make marks like letters with a pen.
The trunk of a fullgrown elephant is about eight feet long. The elephant has such great strength
that he can knock down a man with it.
