Florence Nightingale was a celebrated English nurse and writer. According to a survey,

British people consider her to be one of the most famous British persons along with outstanding

scientists, writers and politicians.

She was born into a rich, upper-class family in 1820, in Italy. She got her name Florence

after the city of her birth, as there was a tradition in her family to name the children in honour of the

city they were born in. She got an all-round education and according to the family’s status Florence

was expected to become a faithful wife and attentive mother.

However, in 1844 Florence decided to become a nurse, despite the intense anger and distress

of her mother and sister. At that time nursing was seen as a job that needed neither education nor

special medical skills.

In 1854 the Crimean War broke out and Florence Nightingale offered her services to the

War Office and soon left for the Crimea with thirty-eight volunteer nurses. They began their work

in the main British camp, in the hospital. Very soon Florence found out that hygiene was neglected,

and fatal infections were common. There was no equipment to cook proper food for the patients.

Florence decided to change the situation.

Nightingale managed to found a vast kitchen and a laundry. In addition to her nursing work,

she tried to organize reading and recreation rooms for the wounded soldiers. She was on her feet for

twenty hours a day and so were the other nurses. Florence was called ‘The Lady with the Lamp’ for

her habit of making rounds round the hospital at night. She checked on her hepless patients.

Florence remained in the Crimea until 1856, then she returned to England.

In London Florence Nightingale visited Queen Victoria and persuaded the Queen of the

need to create a military hospital system. Soon Florence Nightingale set up a training school for

nurses, the first nursing school in the world. It is now called The Florence Nightingale School of

Nursing and Midwifery and is part of King's College in London. The annual International Nurses

Day is celebrated around the world on Florence’s birthday, the 12th of May.

In the Crimea camp, Nightingale got ‘Crimean fever’ and never fully recovered. By the time

she was 38 years old, she was seriously ill. She left her house very rarely and had to stay in bed

most of the time. Nevertheless, Florence continued her work from her bed. She wrote many books,

some of them became the base of the curriculum at the Nightingale School and other British nursing

schools.

Florence Nightingale died in London in 1910, at the age of ninety. The government offered

to bury Florence in Westminster Abbey but her relatives did not agree. However, the memorial

service took place in St. Paul's Cathedral.Florence Nightingale received a lot of honorable awards. Several books were written about

the life of ‘The Lady with the Lamp’ and a few films were shot about her.

Прочитайте отрывок из исторического источника и ответьте на вопросы.Из письма короля Георга III императору Китая (Послано с Маккартни 1792-1793 гг.): Следуя примеру прошлых лет, мы снарядили корабли и послали на них самых мудрых и знающих людей открывать далекие и неизведанные земли. Мы посылали корабли с наиболее полезными людьми, животными и растениями на острова и в те места, они казались нужными. Мы особенно желали познакомиться с искусствами и обычаями стран, где цивилизация в течение многих веков совершенствовалась с помощью мудрых постановлений государей этих стран и их добродетелей. Кроме этого, мы горячо желали ознакомиться с выдающимися учреждениями многолюдной и обширной империи Вашего величества, процветание которой вызывает восхищение всех народов, окружающих ее.Мы счастливы жить в мире со всеми странами. Настоящее время кажется нам чрезвычайно благоприятным для расширения дружеских и благожелательных связей между такими великими и цивилизованными странами, как Китай и Великобритания.Какие цели преследовали англичане в отношениях с Китаем согласно письму короля?
