Antarctica is a snow-covered continent. The average temperature at the South Pole is - 51⁰C. Few plants or animals can live on the land- it is too cold for them. There are few scientists from different countries who live and work on speculial bases in Antarctica. On midsummer's day ( December 22^nd ) there is daylight for 24 hours and so during this period a few tourists ships and planes come to see this strange land. But in winter there is no daylight for months. It must be a terrible place during the winter. The snow is always there - winter and summer - but in fact, little snow falls in the year ( an average of 12 - 20 cm ). People say that it can be a beautiful place. At first, it appears frightening but after a little time, some people fall in love with it.

Read the passage and answer the questions

THE BEST TIME FOR APPLES

It was the first lesson after the summer holidays at a small school in England. The lesson was about the seasons of the year. "There are four seasons in the year", said the teacher. "They are Spring, Summer, Autumn and Winter. In Spring it is warm and everything begins to grow. In Summer it is hot and there are many flowers in the fields and gardens. In Autumn, there are many vegetables and much fruit. Everybody likes to eat fruit. In Winter, it is cold and it often rains. Sometimes there is snow on the ground."

Here the teacher stopped and looked at one of the pupils, "Stop talking, Tom" he said. "Now listen to me. Can you tell us when is the best time of apples?"

"Yes, sir," answered Tom. "It is when the farmer is not at home and there is no dog in the garden."

True (T) or False (F) questions.

_________ In the summer it is cold and there are many flowers in the fields and gardens.

Noise is constant and loud sound. To measure the loudness, or volume of sounds, people use a unit called a decibel. When a sound is louder than 70 decibels, it can cause noise pollution. Do you know that the noise from a vacuum cleaner or a motorcycle can result in permanent hearing loss after eight hours? The sounds of a concert are even more serious. They can reach as high as 130 decibels and may cause immediate and permanent hearing loss. Noise pollution can also lead to headaches and high blood pressure. If you are listening to music through headphones, and other people can hear it. it means the music is too loud and unsafe. If there seems to be a ringing or buzzing in your ears, it means the noise is affecting you and damaging your hearing- Wearing earplugs when you go to concerts or other loud events, and listening to music through headphones or headsets at safe levels can help you reduce the effects of noise pollution.
