Unit 7
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.

高中英语Unit7TheSea单元小结教案含解析北师大必修30605143.doc

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。

英语地球知识点归纳

英语地球知识点归纳地球是我们居住的行星，它是太阳系中离太阳最近的行星。

地球是一个独特而复杂的生态系统，有许多有趣的知识点和信息值得了解。

下面是一些英语地球知识点的详细介绍。

1. 地球的结构：地球由几个不同的层组成，包括地壳、地幔和地核。

地壳是地球最外面的岩石层，约占地球表面积的1%，分为陆地和海洋两部分。

地幔是地壳之下的岩石层，它占据了地球内部约84%的体积。

地核由一个外核和一个内核组成，主要由铁和镍组成。

2. 大洋和海洋：地球表面的71%是水，大部分的水都是存在于海洋中。

海洋是地球上最大的水体，分布于世界各个国家和地区。

大洋有五个，包括太平洋、大西洋、印度洋、南极洲洋和北冰洋。

海洋在地球上有着重要的作用，如调节气候、提供食物资源等。

3. 大陆和板块构造：地球上的陆地主要分布在五大洲上，包括亚洲、非洲、北美洲、南美洲和澳大利亚。

地球表面的陆地和海洋并不是固定不变的，它们是由地壳板块构成的。

地壳板块是地球上的大片岩石，它们以很慢的速度移动，导致大陆的漂移产生。

4. 地球的气候：地球的气候是地球各个地区长期平均的天气条件。

地球的气候受到多种因素的影响，包括纬度、海洋流、高山等。

地球主要有四个季节：春季、夏季、秋季和冬季。

不同地区的气候差异很大，从极地的寒冷到赤道的炎热都有。

5. 地球的生态系统：地球是一个复杂的生态系统，包括地面、大气和水体中的生物群落以及它们之间的相互作用。

生物群落是由不同物种组成的，包括植物、动物和微生物。

地球的生态系统提供了我们生活所需的食物、水和空气等资源。

6. 地球上的自然灾害：地球上发生各种自然灾害，如火山喷发、飓风、洪水等。

这些自然灾害对人类和环境造成了很大的破坏。

是地壳板块移动引起的，它可以导致建筑物倒塌和土地沉降。

火山喷发会喷出岩浆和火山灰，对周围地区造成严重影响。

7. 地球的环境问题：地球面临许多环境问题，如气候变化、空气和水污染、森林砍伐等。

气候变化是由于人类活动产生的温室气体排放引起的，它导致了全球气温上升和极端天气现象增加。
