What do know about the sea? Some people have seen it but others haven't. The sea looks beautiful on a fine sunny day and it can be very tough when there is a strong wind. What other things do you know about it? Of course, the sea is very large. In the world there is more sea than land. If you have swum in the sea, you know that the sea is salty. Rivers carry salt from the land into the sea. Some places of the sea are saltier than the other places. Do you know the Dead Sea? It is so salty that you can't sink when you are in the water! And fish cannot live in it!
你对大海有什么了解呢？有些人见过海但其他人没有见过。大海在晴朗的天气里看起来很美丽，但当有大风的时候会非常可怕。你知道关于大海的其他事情吗？当然，海非常大。在世界上海洋比陆地更多。如果你曾经在海里游泳，你就知道海水是咸的。河流把盐从陆地携带到海洋。有些地方比其他地方的海水更咸。你知道死海吗？它太咸了你是不可能沉到水底的！鱼也不能在死海中生存！
