Unit 7 The SeaThe Great Barrier ReefSome people call it an underwater wonderland.Others call it the most magical place on our planet.We are talking about one of the great wonders of our natural worldthe beautiful and amazing Great Barrier Reef located off the east coast of Australia.The Great Barrier Reef is not just one reef but actually a series of over 2,000 reefs stretching for more than 2,300 kilometres.It is the worlds largest coral reef.A coral reef is a natural barrier made up of the bodies of living and dead coral.Coral reefs exist in warm climates with clear salt water and lots of sunlight.And since coral reefs are also in shallow water，you can actually see them from above the water！All along the Great Barrier Reef，the color of the coral reef changes，as does the color of the water，which varies from a green to a blue color.The best way to experience the magic and beauty of the Great Barrier Reef is to experience it up close and personal，underwater.People who have dived and explored in the Great Barrier Reef claim that it is an underwater wonderland filled with amazing creatures and beautiful sights.This Great Barrier Reef，although beautiful and amazing，is very sensitive to outside forces such as climate change，changes in the patterns of water movement and global warming.Humans are also responsible for damaging the Great Barrier Reef and thus endangering the lives of the animals that live there.If you are one of the lucky people that get the chance to explore this underwater wonderland，be sure to leave everything just the way you find it.1the Great Barrier

dont have troubles are gathered in little neighborhoods.Most communities have at least one.We call them cemeteries.If youre breathing，you have difficulties.Its the way of life.And believe it or not，most of your problems may actually be good for you! Let me explain.Maybe you have heard the Great Barrier Reef，stretching some 1,800 miles from New Guinea to Australia.Tour guides regularly take visitors to view the reef.On one tour，a traveler asked the guide an interesting question.“I notice that the lagoon (泻湖) side of the reef looks pale and lifeless，while the ocean side is vibrant and colorful，” the traveler observed.Why is this?The guide gave an interesting answer，“The coral around the lagoon side is in still water，with no challenge for its survival.It dies early.The coral on the ocean side is constantly being tested by wind，waves and storms.It has to fight for its survival every day.As it is challenged and tested，it changes and adapts.It grows healthy.It grows strong.And it reproduces.”Then he added，“Thats the way it is with every living organism.”Thats how it is with people.Challenged and tested，we come alive! Like coral pounded by the sea，we grow.Physical demands can cause us to grow stronger.Mental and emotional stress can produce toughmindedness and resiliency.Spiritual testing can produce strength of character and faithfulness.So，you have problems？No problem! Just tell yourself，“There I grow again！”Remember：A smooth sea never made a skilled mariner.11Who has no problems according to the passage?AThe persons who are very famous.BThe persons who have much money.CThe persons who have been born.DThe persons who are living in the cemeteries
