VII. Read the text about Arthur Ignatius Conan Doyle and decide whether the statements about it are true (T), false (F), or not given (NG)
ARTHUR CONAN DOYLE
Sir Arthur Ignatius Conan Doyle was a Scottish writer and physician. He is best known for his creation of Sherlock Holmes - a brilliant London-based detective famous for his logical thinking and ability to solve difficult cases.
Born in Edinburgh in 1859 into a prosperous family, Doyle was strongly influenced by his mother, who was a well-educated woman. In his early childhood, she used to tell him vivid stories which sparked his imagination. The second person who had a great impact on his writing career was Dr Joseph Bell, a professor at the medical school where Doyle studied from 1876 to 1881. Dr Bell’s keen powers of observation later inspired Doyle to create his fictional detective character, Sherlock Holmes.
Doyle’s active life provided him with vivid experiences for his stories. With a great love for adventure, he would never miss a chance to travel. He took a surgeon’s position on a whaling ship sailing for the Arctic Circle. He served as a volunteer doctor in the Langman Hospital in South Africa during the War of Independence in 1900. He also acted as a war journalist during the First World War.
Doyle’s writing career started during his time at medical school. After graduation, he set up his own medical practice, which was not very successful initially, so he started writing stories again while waiting for patients. He wrote 21 novels and more than 150 short stories. He also published poems, articles, memoirs and plays on various subjects. His most well-known works are the novels and stories with Sherlock Holmes and the fantasy novel The Lost World, which were made into successful films.
Doyle died at the age of 71, after a heart attack. In his honour, a statue of him was built in Crowborough, where he lived for almost 23 years.

.I. Read the second part of the text and find words or phrases from the two sections of the text which mean the following
There are three main periods in Beethoven’s music career: early, middle and late.
The beginning of his early period was in 1792 when he moved to Vienna, Austria. Beethoven quickly made a name for himself as a talented pianist. His compositions during this period consisted mainly of works for his main instrument, the piano, and were classical in nature. However, Beethoven’s hearing was beginning to deteriorate during this period, and he tried to hide this fact from those around him.
In 1800, Beethoven turned from the classical forms of the previous century to a more expressive or romantic music. His musical imagination began to grow beyond that of the piano. The middle period was believed to be Beethoven’s greatest and most productive stage. In less than a decade, he produced countless masterpieces in every genre.
In 1809, however, his musical creativity began to decline, possibly due to his health problems and mental state. Beethoven stopped conducting and performing in public, but continued to compose – many of his most admired works were created during this period. By 1815, he was almost completely deaf and his manners became increasingly rude. In 1827, he died after a long illness. Nearly 20,000 people lined the streets of Vienna to pay their last respect to the composer who had changed the music scene of Western Europe.

If you want to make your school green, think beyond your classrooms. Here are some suggestions that are all easy and simple to follow, and can make a big difference in reducing your carbon footprint and creating a sustainable community.
One of the places where both teachers and students often spend some of their time is the library. An eco-friendly reading space is likely to create a favourable impression on library users, and bring some significant educational benefits. For example, you can install energy-saving products like fans instead of air-conditioners which consume a lot of energy. You can also use biodegradable dust cloths or old T-shirts to clean the environment. In addition, to raise public awareness, allocate a clearly visible space on the noticeboard for everyday green tips like ‘Let others reuse your book’.
Sporty students may prefer to spend more time in the swimming pool than in the library.
Therefore, keeping this place safe and green will also help to raise their environmental awareness. Remember that chlorinated pool water may cause red eyes and itchy skin to some people if they spend much time in the pool. An ideal alternative would be a salt-water pool, which can be naturally clean and economical. In case warm water is required, think of solar heating to save the environment as one pool with gas or electric heater may emit tons of carbon dioxide each year.
Finally, focus on the school gym, which is perhaps the most interactive and exciting place for all school staff. Think of installing low-flow taps and showers to save gallons of water per minute and energy-saving lights to cut the cost of electricity. Moreover, make sure that the airflow pathways are clear and free of mould, mildew and other allergens.
