1.Read the text below. For questions (1-5) choose the correct answer (A, B, C or D). An example (1) has been done for you. Marie Curie was born in 1867. She is one of the greatest scientists to have ever lived. She was a pioneer in the field of radioactivity and discovered the chemical elements radium and polonium. Curie is the only person ever to win two Nobel Prizes in two different sciences. Other achievements include being the first female professor at the University of Paris.
Curie was born in Warsaw, Poland. Her father was a Maths and Physics teacher and was a big influence on MarieЎ¦s early education. From an early age Marie was an exceptional student with an amazing memory. She often went without food and sleep to study. Her brilliant mind led her to Paris to study and conduct her research. She met her future husband Pierre Curie at the university. He considered Marie to be a genius and instantly wanted to work with her. They got married and spent most of their time together in their laboratory studying radioactive materials. Their research led to the discovery of radium, for which they were honoured with the Nobel Prize in Physics in 1903.
Pierre was killed in 1906 and Marie was devastated and extremely lonely. She threw herself even deeper into her work and won the Nobel Prize in Chemistry in 1911. She spent the 1920s raising funds for more research into radium. In 1934 she died from a condition caused by decades of exposure to radiation. Before that no one knew how deadly radium could be.

An Allergy is a hypersensitivity of the body to any substance. This substance can be any chemical ingredient, product, hair, dust, pollen or a germ. Today it is well established that allergens may be substances produced within the body. They are called antiallergenic or autoallergens. They are natural – unmodified tissue proteins that are isolated from the systems that are responsible for immunity. And purchased – proteins that acquire foreign properties against thermal, radiation, chemical, bacterial, viral, and other factors. For example, an allergic reaction develops with glomerulonephritis, rheumatism, arthritis, hypothyroidism.

Dear John,

Thank you for your letter. I'm sorry for not writing to you sooner, I have been busy at school.

In your letter you asked me about summer in my country. Well, I should say it's really hot here, especially in July and August when the temperatures may reach 45 °C. If you decide to come here in summer, make sure to have a broad brimmed hat.

I like summer anyway, because I don't have to go to school. And what is your favourite season? What is summer like in the UK? How do you spend your summer?

Write back soon.

Best wishes,

ваше имя
