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 22nd ) 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.
