It is dusk. Who is rustling through the grass at the edge of the lake?

Beavers!

Beavers are tireless woodmen, and brilliant builders! They build dams across rivers. They work hardest through the night, from sunset to sunrise.

Beavers only eat plants. They eat the leaves, buds, shoots, bark and roots.

Beavers build dams to make a pool where they can raise their families in safety. All the beavers bring mud and branches to build the dam. The river soon looks like a building site!

The beavers are well protected in their lodge!

Beaver parents pair for life and look after their family together.

Otters have been hunted for their fur and because some people think they take too many fsh from the rivers. Now they are quite rare.

The sea otter spends its whole life in the water.

We do not need to kill these animals and take their fur to keep ourselves warm. A sheep can give us its wool every year.

fur [fзː] n. 毛皮 wool [wʊl] n. 羊毛

( ) Beavers are brilliant builders.

(----) Beavers eat plants and animals.

海狸又名河狸，属于河狸科，是世界现存最古老的动物之一，有动物世界“建筑师”和古脊椎动物“活化石”之称。许多人认为海狸生性冲动，只会啃树干。海狸只需六秒钟就能咬断直径二十五厘米的树干。但这并不是因为海狸心情焦虑，而是与它的牙齿有关。海狸如果不用牙齿咬东西，它的牙齿就会一直生长，直到刺穿下颚。

水獭傍水而居，多居于自然洞穴。它们昼伏夜出，以鱼、鼠、蛙、蟹、水鸟等为主食。它们具有流线型的身体，善于游泳和潜水，一次可在水下停留两分钟，捕起鱼来像猫捉老鼠一样敏捷。根据动物学家的研究，海獭原是栖息于河川中的水獭，在大约五百万年前移居海边进化成了海獭。
