The Great Barrier Reef is one of the most stunning natural wonders in the world. Located off the coast of Queensland, Australia, it stretches over 2,300 kilometers and is composed of thousands of individual coral reefs. In this article, we will explore the beauty and importance of the Great Barrier Reef.

1. Biodiversity:

The Great Barrier Reef is home to an incredible array of marine life, making it a biodiversity hotspot. It is estimated that there are over 1,500 species of fish, 400 species of coral, and 4,000 species of mollusks living in the reef. In addition, it provides a habitat for numerous other animals such as turtles, dolphins, and sharks. The reef is truly a vibrant ecosystem that supports a delicate balance of life.

2. Environmental Importance:

Apart from its beauty, the Great Barrier Reef plays a crucial role in maintaining the health of our planet. It acts as a natural barrier, protecting the coastline from erosion and storm damage. The reef also absorbs carbon dioxide from the atmosphere, helping to mitigate climate change. Furthermore, it is a significant source of food and income for local communities through tourism and fishing activities.

3. Threats and Conservation Efforts:

Unfortunately, the Great Barrier Reef is facing numerous threats. Climate change, pollution, and overfishing are some of the major challenges it is currently dealing with. Rising sea temperatures due to climate change have led to coral bleaching, causing the death of large sections of the reef. In response, various conservation efforts have been initiated to protect and restore the reef. These include reducing carbon emissions, improving water quality, and implementing sustainable fishing practices.

4. Visitor Experience:

For those fortunate enough to visit the Great Barrier Reef, there are numerous activities to enjoy. Snorkeling and scuba diving are popular choices, allowing visitors to witness the breathtaking beauty of the underwater world. Glass-bottom boat tours and helicopter rides provide alternative ways to explore the reef without getting wet. It is important to remember, however, to respect the reef and follow responsible tourism practices to minimize any negative impact on this fragile ecosystem.

Conclusion:

The Great Barrier Reef is a natural wonder that captivates the imagination and inspires awe. Its biodiversity, environmental importance, and unique beauty make it a destination worth protecting. By raising awareness and taking action to preserve the reef, we can ensure that future generations will have the opportunity to experience this magnificent natural treasure.

Unveiling the Mystery of Ubudsen - A Stone Forest

Introduction:

Ubudsen, also known as the Stone Forest, is a hidden gem located in a remote area of Scandinavia. This unique geological formation, reminiscent of a forest made entirely of stone, has fascinated scientists and adventurers for centuries. In this article, we will explore the beauty and mystery of Ubudsen.

1. Formation and Characteristics:

Ubudsen is believed to have been formed millions of years ago during the last Ice Age. The area was once covered by glaciers, which eroded the existing rocks and shaped them into their current form. The result is a landscape that resembles a forest, with towering stone pillars and intricate rock formations. The stones vary in size, with some reaching heights of over 30 meters.

2. Geological Significance:

The Stone Forest of Ubudsen is not only a visual spectacle but also a geological wonder. The unique formation provides valuable insights into the Earth's history and the processes that have shaped our planet. Scientists have been studying the rocks and the surrounding area to understand the geological forces at work during the Ice Age and the subsequent changes that have occurred.

3. Folklore and Myths:

Ubudsen holds a special place in the local folklore and mythology. According to ancient legends, the stone pillars are the petrified remains of giants who once roamed the land. The area is said to be enchanted, with tales of mysterious happenings and supernatural beings. These stories have added to the allure of Ubudsen, attracting curious visitors from around the world.

4. Exploring Ubudsen:

For those brave enough to venture into the Stone Forest, there are various hiking trails and guided tours available. Visitors can marvel at the towering stone pillars, explore hidden caves, and witness the unique flora and fauna that have adapted to this rocky environment. It is important to note that the area is protected, and visitors are encouraged to follow designated paths and respect the natural surroundings.

Conclusion:

Ubudsen, with its mystical beauty and geological significance, is a destination that offers a truly awe-inspiring experience. The Stone Forest invites us to ponder the forces of nature and the mysteries of our planet's past. By preserving and appreciating this natural wonder, we can continue to unravel its secrets and share its magic with future generations.

1.I have some difficulty in pronouncing some of the words in English .

在某些英语单词的发音上我有些困难。

have some difficulty (in) doing sth

这是一个很常见的句型。意思是“在做某事方面有困难”。

其中介词in常可省略。在此句型中difficulty是用作不可数名词，所以前面不能加不定冠词“a”，也不能改为复数形式。但difficulty前可加any , no等词，例如：

Do you have any difficulty in translating this sentence into English ?

你把这句子翻译成英语有困难吗？

WE HAD NO DIFFICULTY IN FINDING HIS HOUSE YESTERDAY EVENING . (=WE DIDN’T HAVE ANY DIFFICULTY……)

昨晚，我们毫不费劲地就找到了他的家。

2.When do you take your near exams ?

你们下一次考试是什么时候？

注意本句中用一般现在时表示将来发生的动作。本句相当于：When will you take your next exams ?

此句用法只限于将来的事件是“列入日程”的，也就是说，是按计划或时刻表将要发生的事，则可以用一般现在时来表示将来。

例如：

When does the winter vocation begin ?

寒假什么时候开始？

What time does the train leave for Shanghai ?

开往上海的列车几点开车？

The plane takes off at ten A.M.

飞机上午十点起飞。

3.Pardon ? Would you please say that again more slowly ?

对不起，请慢点再说一遍好吗？

Pardon ? =Beg pardon ? =I beg your pardon?

是“对不起，请原谅”的意思。这里当没听清楚或没听懂对方话时，希望对方重复一遍的礼貌用语。意思是“I didn’t hear／understand what you said”同下句“I’m sorry , I don’t quite follow you .”一样，也是希望对方重说一遍的用语。

4.Written English is more or less the same in both Britain and America , though there are some spelling differences .

在英国和美国，书面英语大体上是相同的，尽管在拼法上有些差异。

more or less 作“或多或少”、“大约”、“差不多”、“几乎”解。

我差不多已经把这本书看完了。

It took more or less a whole day to paint the ceiling .

粉刷天花板用了大约一整天的时间。

起初，这种语言同在英国使用的语言仍然相同，但是，慢慢地它开始在一个又一个地区发生变化。

1)句中的stay是连系动词，作“保持（某种状态）”解。相当于remain , keep的意思。通常后边跟形容词作表语。

例如：

这家餐馆一直营业到12点。

有的时候，美国，加拿大或澳大利亚所说的英语发生了变化；但有的时候，这些地方所说的英语保持不变，而英国说的英语发生了变化。

1)在句中“spoken in America or Canada or Australia”和“the language”，其作用相当于定语从句。

如：Sometimes , the English which was spoken in America or Canada or Australia changed ; but sometimes the language (Which was spoken)in England changed .

2.which在句中是并列连词，表示两种情况的对照，对比或相反的情况，意思是“进而”、“而”、“却”。

英语世界通行，而土耳其语离开本国就很少有人说了。

8.But Americans still talk about “fall” just as people do in some parts of western England .

但是，美国人还是说“fall”，就像英格兰有些地区的人说“fall”一样。

1)本句中的助动词do与下句“In the same way Americans use the expression”I guess “(meaning “I think ”) just as the British did 300 years ago .”中的did的.用法是相同的。它们分别代替上文中出现过的谓语动词“talk”和“use”，以避免不必要的重复。

2)just as , as是连词，引导一个表示方式的状语从句，意思是“正如”，“恰似”，“按照”。

例如：

现在他们当中许多人都失业了。

10.There are several reasons for this .

1)the／ one’s reason for sth or doing sth是一个固定搭配的用法，作“…的原因、理由”解，the reason后不能用of。

the reason why +从句，意思也是“…的原因”。在口语中也可以用the reason that .

例如：

告诉我你做那件事的理由。

What is the reason for your hurry ?

你为什么这么匆忙？

This is the reason why he didn’t pass the examination .

这就是他考试不及格的原因。

The reason that he didn’t pass the exam was that he didn’t work hard enough .

他考试不及格的原因是学习不够努力。

3)reason与cause的区别。

reason与cause作名词时都有“原因”和“理由”的意思。reason通常指产生某种行为或想法的推理上的理由，而cause通常指导致某一事件发生的起因。reason常和for连用，而cause常和of连用。

例如：

Please give me your reason for absence .

请你把缺席的理由告诉我。

The cause of the fire is still unknown .

这场大火的起因还不知道呢。

11.…they also brought in some words from their own languages .

四、【背景知识】

英国英语和美国英语之间的区别主要有以下几个方面：

1)在词汇方面的区别：

gas／gasoline(美)──petrol(英)； baggage(美)──luggage(英)；

package(美)──parcel(英)； mail(美)──post(英)；

movie(美)──film(英)； subway(美)──underground(英)；

stairway(美)──staircase(英)； soccer(美)──football(英)等。

2)在拼写方面的区别：

check(美)──cheque(英)； jail(美)──gaol(英)；

tire(美)──tyre(英)；

美国英语一般用—or词尾，英国英语用—our词尾：

color──colour； favor──favour；

labor──labour等。

美国英语用—er词尾，英国英语用—re词尾：

center──centre； meter──metre；

theater──theatre等。

美国英语不双写辅音字母l，英国英语要双定辅音字母l：

marveled──marvelled； quarreler──quarreller；

traveling──travelling等。

3)在读音方面的区别：

again[′gein](美)──[′gen](英)；clerk[kl:k](美)──[kla:k]；

laboratory[′lebrtri](美)──[l′brtri](英)；

此外，像dance , class , fast , half , past这些词中的元音字母a ，美国英语读作[ e ]，英国英语读作[ a :]，如[dens](美)──[da :ns](英)；[kl es](美)──[kla :s](英)；[f est](美)──[fa:st](英)等。

4)语法方面的区别：

在表示汉语“有”的概念时，美国英语多用动词have，英国英语多用动词完成式have got。

例如：I have a new car.(美)──I have got a new car.(英)。又如，美国英语说I insisted that everything be ready by six o’clock that evening，而在当前标准英国英语里，这类虚拟语气形式是“should”+动词原形，也就是：I insisted that everything should be ready by six o’clock that evening .

尽管美国英语和英国英语有着上述的一些区别，但这些区别并不影响相互之间的交际。
