Zheng He and His Seven Voyages
Zheng He(1371—1435) was one of China's most famous explorers.Towards the end of the fourteenth century，his fleet sailed to countries very far away.
Zheng He had over 300 ships，some of which were over 150 metres long and could carry up to 1，000 people.In addition to the supplies for the long journeys，the ships carried gold，silver，silk，china and other treasures to give as gifts to the rulers of the neighbouring countries.Some of the ships even had earth on board so that the sailors could grow their own crops for food.
On Zheng He's first voyage，he set sail across the Indian Ocean.His fleet travelled for many days far away from land.One day，they were hit by a

storm. All the sailors thought the fleet was going to sink.Then a strange light appeared at the top of the ships' masts，and after that，the storm passed.The strange light that appeared on the masts was probably electricity from the thunderstorm.Many sailors today see such lightning on the masts of their ships during a storm.
Zheng He completed seven famous voyages between 1405 and 1433.He visited many countries in Asia and Africa.Zheng He also brought back many gifts from the countries he visited，such as medicines，pearls and strange animals. The most famous of these gifts were a giraffe and a zebra.
When Zheng He came back from his seventh voyage in 1433，he was sixty two years old.In 28 years of travelling，he had managed to share the glory of China with many different countries.When he died in 1435，the stories of his travels made him one of China's most famous sailors.

横跨大海
贸易和好奇心奠定了人类最伟大成就的基础，早期文明的人们对勾勒出完整的世界版图满怀激情。马可·波罗的故事激励了欧洲探险家去寻找由西方通往东方的海上航线。而东方的商人和探险家们早在哥伦布首次航行前很多年就已经开始从东半球向西半球航行了。
在古代，中国的丝绸通过陆路运达印度、中东和罗马，这条路就是有名的“丝绸之路”。一条横跨海洋的贸易路线也沿着印度洋海岸延伸开来，以锡兰(现在的斯里兰卡)为中心。在这里，来自中国和许多其他地方的商人聚在一起洽谈贸易，也增进了对彼此文化的了解。几个世纪以来，随着贸易的发展，中国西部地区得到了更多的探索，正如8世纪时，杜环在《绍行记》中所记载的那样。
一品课堂·高中同步导学案·英语 选择性必修 第四册
后来，明朝时的中国和这些地区的关系得到了进一步发展。1405年到1433年间，七支大型船队西渡重洋，进行贸易和探险活动。这些船队在当时蔚为壮观，独领风骚。在郑和的指挥下，他们从中国南海起航，穿过印度洋，到达红海入海口，然后到达了非洲东海岸。非洲皇室向船队赠送长颈鹿等礼物以示友谊，船队则回赠了黄金、丝绸和香料。虽然中国在1433年以后就停止了进一步的海上探索，但这些陆上和海上路线在接下来的几个世纪里仍然是其他文化之间进行交流的繁忙通道。
在今天，人们跨越海洋的愿望依然强烈。郑和走过的古航线现在正被重新开发成“21世纪海上丝绸之路”这是“一带一路”倡议的一部分。这一倡议旨在促进具有历史意义的“丝绸之路”周边地区的合作和贸易，并加强中国与世界其他地区的联系。沿线贸易近年来大幅增长，并将在未来几年继续增长。中国已投资了数十亿元用以建设沿线的系统和服务设施，这将有助于推动整个地区发展，促进未来的贸易和文化交流。
一品课堂·高中同步导学案·英语 选择性必修 第四册
中国还与大洋彼岸的伙伴在其他重要项目上开展了合作。虽然郑和的古航路已经被重走了很多次，但还有很多其他地方有待探索。近年来，中国与其他国家一起进行了多次北极探险。从科学的角度来看，我们确实迫切需要研究北极，以了解气候变化及其影响。
数百年后，掌握最新的科学技术，未来中国将不断探索海洋，进一步促进贸易，加强与他国的联系。

When people talk of exploring the sea more，they usually mean exploiting① it.Sea exploration has caused many problems and will continue to cause more.
More exploration means more pollution.The Deepwater Horizon spilled② over 200 million gallons③ of oil into the sea in 2010.Plastic pollution is also bad，killing many birds and fish【1】，and has even been found in our tap water.
【1】 此处是v ing短语作结果状语，表示自然而然的结果。
Mining for resources is very damaging，especially in the Arctic.Because of climate change，there is less ice now，which means we can look for more fossil fuels④ further north.But if we burn these，the ice will melt more and this negative cycle⑤ will continue.Climate change is warming us that something is very wrong.

To truly understand our planet，we must explore the oceans which cover most of it.Opponents⑩ may be concerned ，but sea exploration is important for our future.For example，scientific research ships can help address important issues such as climate change.We need to understand what is happening to our planet so that we can take action 【2】．Therefore，more research is necessary.

Understanding more about the sea will also help us manage its resources better. Logging new species will improve our understanding of life on the earth. It may help us discover new medicines，as well as new sources of food and energy.Accessing the deep ocean may also help us to predict events such as earthquakes.
The population of the world is growing and we need new resources for future development.
There are probably vast amounts of resources under the sea and ice，not just oil and gas but also valuable minerals.
Of course，there are still environmental risks.However，these should be balanced with economic needs.Hopefully，as technology improves 【3】，we may have more options for managing this balance.

人们谈到进一步探索海洋时，通常指的是开发它。海洋探索已经造成了许多问题，未来将带来更多问题。
探索越多，意味着污染会越严重。2010年，“深水地平线”钻井平台泄漏了2亿多加仑的原油到海水中。塑料污染问题也很严重，它造成许多鸟类和鱼类死亡，甚至在我们使用的自来水中也发现了塑料污染。
开采资源会严重破坏环境，尤其是在北极地区。由于气候变化，现在北极的冰越来越少，这意味着我们可以到更靠北的地方寻找更多的化石燃料。但是如果燃烧这些燃料，北极的冰会融化得更多，这个恶性循环就会持续下去。气候变化正在警示我们，事态已经十分严峻。

过度捕捞是另一个问题。有人捕杀鲸鱼和海豚以获取它们的肉或用于所谓的研究。虽然国际社会1982年就已禁止这种行为了，但一些国家仍然毫无怜悯地“谋杀”这些聪明的生物。
海洋是生命的家园，而不是人类的所有物。海洋宽广辽阔，但它比我们想象的更敏感脆弱，如果我们不好好保护它，子孙后代是不会原谅我们的。

要真正了解我们的星球，我们必须探索覆盖了地球表面绝大部分面积的海洋。反对者可能会担心(环境问题)，但海洋探索对我们的未来很重要。例如，科考船可以帮助我们应对诸如气候变化等重要问题。我们需要了解我们的星球正在发生什么，这样我们才能采取行动。因此，我们有必要开展更多的研究。
更好地了解海洋也有助于我们更好地管理海洋资源。记录新物种将增强我们对地球上生命的了解。这可以帮助我们发现新的药物，以及新的食物和能源。探索深海还可能帮助我们预测地震等自然灾害。
世界人口正不断增长，我们需要新的资源来促进未来的发展。海底和冰层下可能蕴藏着丰富的资源，不仅有原油和天然气，还有珍贵的矿产。
当然，环境风险仍然存在。但我们应尽量在经济需求和环境保护之间达成平衡。随着技术的进步，我们有望拥有更多的选择，来实现这种平衡。

这一天以各种方式举行纪念活动，包括发起新的运动和倡议，以及举行特别活动，所有这些都是为了促进海洋保护和海洋教育。
all working to advance...为独立主格结构，作状语。
独立主格结构是带有自己的逻辑主语的非谓语动词分句或无动词分句。由于在语法上有自己的逻辑主语，其在结构上与主句无关系，因此称之为“独立主格结构”。其实，所谓“独立主格结构”并非真正独立，它还是一种从属分句，与主句紧密联系在一起，共同表达一个完整的意思，通常在句中作状语。独立主格结构可放在句首、句尾，用逗号和主句隔开。
一品课堂·高中同步导学案·英语 选择性必修 第四册
独立主格结构可以分为两部分：一部分是名词或代词，起逻辑主语的作用；另一部分是非谓语动词(现在分词、过去分词、不定式)或名词、形容词、副词或介词短语，表示前面名词或代词的动作或状态。基本形式是“名词/代词＋现在分词/过去分词/不定式/名词/形容词/副词/介词短语”。

一品课堂·高中同步导学案·英语 选择性必修 第四册
Ⅲ.要点精析
动词不定式
动词不定式(to＋动词原形)是非谓语动词的一种形式，在句中不能单独作谓语。不定式不受主语人称和谓语动词时态变化的影响。不定式在句中可以作主语、宾语、表语、定语、状语、宾语补足语等。
一、动词不定式形态变化
一品课堂·高中同步导学案·英语 选择性必修 第四册
时态变化 主动语态 被动语态
不定式的一般式 to do to be done
不定式的进行式 to be doing /
不定式的完成式 to have done to have been done
不定式的完成进行式 to have been doing /
二、动词不定式的否定式：not＋to do
She persuaded me not to go to the dangerous area.
她说服我不要去那个危险的地方。
三、动词不定式的句法功能
动词不定式在句中不能独立作谓语，但可以作主语、宾语、宾语补足语、定语、表语和状语等多种成分。
1．作主语
To talk with him is a great pleasure.
和他谈话是一件非常愉快的事。
一品课堂·高中同步导学案·英语 选择性必修 第四册
(1)为了避免头重脚轻，通常都将作主语的不定式置于句子后面，用it作形式主语，放在句首。
(2)若要说明不定式的动作的执行者，可以在不定式前加上“for/of＋n./pron.”结构。当形容词表达事物的特征时用for sb.；当形容词表达人所具有的特征或品质时用of sb.，这样的形容词有careful，cruel，foolish，brave，good，honest，kind，rude，polite，nice，stupid，wise，wrong等。
It's very important for you to remember this.
对你来说记住这一点很重要。
It's very kind of you to help me.
你能帮我真是太好了。
一品课堂·高中同步导学案·英语 选择性必修 第四册
2．作表语
不定式作表语主要有三种情况，一是用于seem，appear，prove，turn out等连系动词之后的不定式(尤其是to be)；二是像My job is to sweep the floor(我的工作就是擦地板)这样的主语与表语“等价”的情形；三是表示想法、约定、义务、命令、可能性、命运等。
He seems to be ill.
他似乎生病了。
Her wish is to be a teacher.
她的愿望是当一名教师。
We are to meet at the bus station at three.
我们约定3点钟在车站见面。(表约定)
一品课堂·高中同步导学案·英语 选择性必修 第四册
3．作宾语
常接不定式而不接动名词作宾语的动词及短语有：
“决心学会想希望”：decide/determine，learn，want，hope/wish/ expect/ long
“设法假装在拒绝”：manage，pretend，refuse
“主动答应选计划”：offer，promise，choose，plan
“同意请求帮一帮”：agree，ask/beg，help
外加 afford，fail，would like/love，threaten。
I can't afford to buy a car.我买不起汽车。
I like swimming，but I don't like to swim this afternoon.
我喜欢游泳，但我今天下午不想游泳。
一品课堂·高中同步导学案·英语 选择性必修 第四册
不定式作宾语后跟宾语补足语时，常把不定式后移而用形式宾语 it 代替，常见句式：think/believe/consider/find/feel，etc.＋it＋adj./n.＋不定式。
I think it necessary to send for an expert.
我认为请位专家来是有必要的。
