The sea
De咸呢？
Have you ever noticed that，in the summer，when your sweat dries it will leave marks on your Tshirt？The marks are tiny bits of salt. If you go to the seaside， you will know that seawater does the same to your clothes，because it also has a lot of salt in it. Water evaporates ( 蒸 发 ) from the surface of the sea but the salt remains.Have you ever thought about whether the seas will keep getting saltier ？ The answer is no.The oceans have stayed at about 3.5 per cent salt content for hundreds of millions of years.It maintains a constant level of salt in different ways.
Pick up a clamshell (蛤壳) and weigh it in your hand.It is heavy.All creatures need sodium (钠)) to live and most need calcium to build bones and shells.The clam，like all sea creatures，gets its sodium and calcium from seawater.When creatures die，their salt is locked up in bones and shells，which drop to the bottom of the sea. Reactions between seawater and rocks are not just one way.Sea salt not only dissolves (溶解) from rocks； it also reacts with the rocks of the ocean crust (地 壳) and volcanic lava (熔岩)． The reactions take some of the salts in seawater away from the sea.

Unit 7 The SeaThere were once lived some sailors in a village near the sea, who made a living by fishing. Since their ancestors were explorers, they all inherited the spirit of adventure.Because of overfishing and industrial and agricultural pollution from chemicals, there were fewer and fewer fishes in the coastal waters. So they had to travel further in search of more fishes.One day, they set sail for deepsea fishing. Before their journey, they had a debate about where to go. Since Jack was the oldest of them, everything was done according to his instructions. Jack, though in his forties, was intelligent and energetic. He persuaded others to make a voyage of adventure.After a day's voyage, they eventually reached an unknown area they had never been to before. They were trying to recognise where they were. All at once, a man screamed with terror “Watch out! Sharks！”They were surprised to find that they were surrounded by dozens of sharks, each at a length of 5 to 10 metres. What a horrible scene! Everyone felt terrified. Obviously they had got into trouble. Jack began to regret and apologised for his risky decision.But now they must find a solution to handle the sharks. They had no choice but to battle with the sharks because they could hardly escape.A fierce battle began. Everyone took up their weapons to fight against the sharks. With their joint efforts, they finally survived the adventure.从前，在靠近海边的一个村庄里，住着一些水手，他们以捕鱼为业。
