Undersea World海底世界

The undersea world is very beautiful. Now more and more people want to dive in the water to find the secret there. Scuba diving is popular today. It can take you into a wonderful undersea world.

You will find many strange animals in the sea. Some are as large as a school bus. Some sea animals give out light in the dark and some have sharp teeth.

During the day， there is enough light. Here， under the sea， everything is blue and green.

When fish swim nearby， you can catch them with your hands. When you have bottles of air on your back， you can stay in deep water for a long time. However， you cant dive too deep. And you must be very careful when you dive in deep water.

海底世界非常美。现在越来越多的人想潜入海中，去探知那里的秘密。水肺潜水如今很受欢迎，能够带你进入奇妙的海底世界。

你可以发现许多奇特的海洋动物。有的大如校车，有的在暗处发光，有的有利齿。

白天有充足的阳光，而在海底，一切都是蓝色和绿色的。

当鱼群从身旁经过时，你可以徒手捉鱼。当你背着氧气瓶时，你可以在深水区待很长时间。但你不能潜到过深的地方。在深水区潜水时，你要非常小心。

The deep sea is not an easy place to live in. Its cold， and its dark， too. The deeper it is， the less sunlight there is. At about 3，000 feet， there is no light at all. It is very dark in the sea. Some fishes have no eyes. Some have big eyes. A few have eyes on one side.

Besides the cold and the darkness， deep-sea animals face a third danger—other animals.

Animals eat！ They must find food to eat. Many animals eat plants. However， some animals eat meat. This means these sea animals have two big jobs. They need to find animals as food， and they have to try not to become other animals meal.

深海可不是容易生存的地方。那里又冷又暗。越是深處，阳光越少。在海中大约3000英尺深的地方，根本就没有光亮。海里非常黑，有的鱼没有眼睛，有的眼睛很大，有少数眼睛长在一侧。

除了寒冷和黑暗，深海动物还面临着另一种威胁——别的动物。

动物是要吃东西的！它们必须寻找食物。许多动物吃植物。然而，有些动物食肉。这意味着这些海洋动物有两项任务。它们需要寻找作为食物的动物，它们也必须设法不成为别的动物的美餐。
