They survive in some of the coldest environments in the world - but even penguins appreciate a warm woolly jumper once in a while.

The mini knitted garments have helped save hundreds of flightless birds caught in oil spills providing protection from the elements and stopping them from ingesting poisonous pollution.

Knits for Nature a program run by The Penguin Foundation which conserves the little penguin population of Phillip Island 140km south-east of Melbourne has created up to 300 different designs over the years - and its all thanks to talented volunteers.

‘There’s a lot of hidden creativity out there said Lyn Blom of the Phillip Island Nature Park.

People love to know that they’re helping the penguins because they’re so cute and small and they waddle up the beach and they’re so feisty. But they need to be they live in a pretty tough sort of environment.’

A thumbnail-sized patch of oil can kill little penguins the smallest of the species measuring just 13 inches (33cm) and weighing 2.2lbs (1kg). The oil separates and mats their feathers breaking natural waterproofing and heating functions.

Ms Blom estimates she has knitted between 200 and 300 penguin jumpers over the years including ones in the colours of every Australian Rules football team in the country.

A staff member read an article in an English women’s magazine about knitting for guillemot birds and decided to adapt the designs.

‘There’s an awful lot of ladies out there who used to knit for their children and grandchildren. These ladies have spare wool and idle hands and they love to feel loved and needed and we love and need them’ said Ms Blom.

The Penguin Foundation recently staged a competition for the most creative jumper which received an enthusiastic response.

The Penguin Foundation rescues approximately 20 birds a year. They even have a stockpile of jumpers in case of emergency - such as the large oil spill near Phillip Island in 2001.

In that instance 453 Little Penguins were affected 96 percent of which were saved - most thanks to the jumpers.

企鹅在世界上最寒冷的环境下生存，但有时候它们也渴望有一件温暖的毛衣。

由于石油泄露，企鹅们很可能接触到石油中的微量元素，甚至误食这些有毒的污染物。而迷你毛衣能给它们很好的保护，成功拯救了数百只企鹅。

为了保护菲利普岛(墨尔本东南部140千米处)上的小企鹅，企鹅基金会发起了为企鹅织毛衣的活动。到目前为止，基金会已经设计了300多种不同的毛衣款式，这都要感谢心灵手巧的志愿者们。

菲利普岛上自然公园的工作人员布洛姆说：“我们发现了很多隐藏的创意。”

“人们愿意帮助企鹅，因为它们又小又可爱，活跃极了。在沙滩上摇摆着身体走动时，它们又显得那么坚强。 这又是必然的，毕竟它们生活在这么恶劣的条件下。”

一滩指甲盖大小的石油就足以杀死一只小企鹅。最小的企鹅大概只有13英寸(33厘米)长，体重2.2磅(1千克)。石油会使得它们的羽毛缠结在一起且分散开，这样羽毛就失去了防水和保温的作用。

布洛姆自己就织了大约两到三百件毛衣，她还制作了一个毛衣系列，采用的是澳大利亚所有足球队的代表颜色。

之所以采用毛衣，是因为基金会的一名员工在一本女性杂志上看到了一篇给海鸟织毛衣的文章，随后就决定模仿这一设计。

布洛姆说：“许多女性朋友为自己的孩子织毛衣，她们乐意帮助我们，也会提供多余的毛线和手工，她们喜欢这种被爱被需要的感觉。基金会也非常感谢和需要她们。”

最近，企鹅基金会举办了一场“最具创意毛衣”大赛，获得了不错的反响。

每年，企鹅基金会拯救的企鹅大约在20只。他们甚至还有毛衣储备以应对紧急情况，比如2001年菲利普岛附近的大规模石油泄露事件。

那次事件中，453只企鹅受到了影响，当中96%的企鹅获救——最大的功臣就是毛衣了。

I am xxx. I was born in Changsha. I graduate from senior high school and major in English. I started learning English since I was 12 years old. My parents have a lot of American friends. That’s why I have no problem communicating with Americans or others by speaking English.

In my spare time, I like to do anything relating to English such as listening to English songs, watching English movies or TV programs, or even attending the activities held by some English clubs or institutes. I used to go abroad for a short- term English study. During that time, I learned a lot of daily life English and saw a lot of different things.

I think language is very interesting. I could express one substance by using different sounds. So I wish I could study and read more English literatures and enlarge my knowledge.

I am pleased to serve as your guide today.

This is the palace museum; also know as the Purple Forbidden City. It is the largest and most well reserved imperial residence in China today. Under Ming Emperor Yongle, construction began in 1406. It took 14years to build the Forbidden City. The first ruler who actually lived here was Ming Emperor Zhudi. For five centuries thereafter, it continued to be the residence of23 successive emperors until 1911 when Qing Emperor Puyi was forced to abdicate the throne .In 1987, the United Nations Educational, Scientific and Cultural Organization recognized the Forbidden City was a world cultural legacy.

It is believed that the Palace Museum, or Zi Jin Cheng (Purple Forbidden City), got its name from astronomy folklore, The ancient astronomers divided the constellations into groups and centered them around the Ziwei Yuan(North Star). The constellation containing the North Star was called the Constellation of Heavenly God and star itself was called the purple palace. Because the emperor was supposedly the son of the heavenly gods, his central and dominant position would be further highlighted the use of the word purple in the name of his residence. In folklore, the term ”an eastern purple cloud is drifting” became a metaphor for auspicious events after a purple cloud was seen drifting eastward immediately before the arrival of an ancient philosopher, LaoZi, to the Hanghu Pass. Here, purple is associated with auspicious developments. The word jin (forbidden) is self-explanatory as the imperial palace was heavily guarded and off-explanatory as the imperial palace was heavily guarded and off-limits to ordinary people.

The red and yellow used on the palace walls and roofs are also symbolic. Red represents happiness, good fortune and wealth. Yellow is the color of the earth on the Loess Plateau, the original home of the Chinese people. Yellow became an imperial color during the Tang dynasty, when only members of the royal family were allowed to wear it and use it in their architecture.

The Forbidden City is rectangular in shape. It is 960 meters long from north to south and 750 meter wide from east west. It has 9,900 rooms under a total roof area 150,000 square meters .A 52-meter-wide-moat encircles a 9.9-meter—high wall which encloses the complex. Octagon —shaped turrets rest on the four corners of the wall. There are four entrances into the city: the Meridian Gate to the south, the Shenwu Gate(Gate of Military Prowess) to the north, and the Xihua Gate(Gate of military Prowess) to the north, and the Xihua Gate(Western Flowery Gate )to the west ,the Donghua (Eastern Flowery Gate) to the east.

Manpower and materials throughout the country were used to build the Forbidden City. A total of 230,000 artisans and one million laborers were employed. Marble was quarried from fangshan Country Mount Pan in Jixian County in Hebei Province. Granite was quarried in Quyang County in Hebei Province. Paving blocks were fired in kilns in Suzhou in southern China. Bricks and scarlet pigmentation used on the palatial walls came from linqing in Shandong Province .Timber was cut ,processed and hauled from the northwestern and southern regions.

The structure in front of us is the Meridian Gate. It is the main entrance to the forbidden City. It is also knows as Wufenglou(Five-Phoenix Tower). Ming emperors held lavish banquets here on the 15th day of the first month of the Chinese lunar year in hornor of their counties .They also used this place for punishing officals by flogging them with sticks.

Qing emperors used this building to announce the beginning of the new year. Qing Emperor Qianglong changed the original name of this announcement ceremony from ban li(announcement of calendar)to ban shou(announcement of new moon )to avoid coincidental association with another Emperor` s name, Hongli, which was considered a taboo at that time. Qing Dynasty emperors also used this place to hold audience and for other important ceremonies. For example,when the imperial army returned victoriously from the battlefield ,it was here that the Emperor presided over the ceremony to accept prisoners of war.

(After entering the Meridian Gate and standing in front of the Five Marble Bridges on Golden Water River)

Now we are inside the Forbidden City.Before we start our tour, I would like to briefly introduce you to the architectural patterns befour us .To complete this solemn, magnificent and palatial complex, a variety of buildings were arranged on a north-south axis, and 8-kilometer-long invisible line that has become an inseparable part of the City of Beijing. The Forbidden City covers roughly one –third of this central axis. Most of the important building in the Forbidden City weree arranged along this line. The design and arrangement of the palaces reflect the solemn dignity of the royal court and rigidly –stratified feudal system.

The Forbidden City is divided into an outer and an inner count.We are now standing on the southernmost part of the outer count. In front of us lies the Gate of supreme Harmony .The gate is guarded by a pair of bronze lions ,symbolizing imperial power and dignity. The lions were the most exquisite and biggest of its kind. The one on the east playing with a ball is a male, and ball is said to represent state unity. The other one is a female. Underneath one of its fore claws is a cub that is considered to be a symbol of perpetual imperial succession. The winding brook before us is the Golden Water River. It functions both as decoration and fire control .The five bridges spanning the river represent the five virtues preached by Confucius :benevolence, righteousness, rites, intellence and fidelity. The river takes the shape of a bow and the north-south axis is its arrow. This was meant to show that the Emperors ruled the country on behalf of God.
