Task 2. Read the text about Ideal Place to Live (6 баллов)

When it comes to thinking of the ideal place to live two things come to mind. The big bustling city or a small quiet town. My choice would be the small town for several reasons. One it’s quiet. There are not a lot of people which can help cut down on crime and violence. Third there are a lot of different sights and sounds that you don’t get to see nor hear in a big city. Last but not least you normally have a better school system in small towns.
Population in the big city can be overwhelming to some individuals. That’s why I would choose the small town. The town in is small enough that you can get to know your neighbors. That can help you notice if something is not right or out of the norms.
Sights and sounds of the small town are like those of a fairy tale if you’ve lived in a big city your whole life. You can actually lay out at night look at the stars. Listen to the stream run pass your house. Watch an owl fly through the air looking for prey. On bright moonlit winter night you could even catch a herd of deer walking thru your yard. In the big city you rarely ever have that kind of opportunity to see those things.

Choose the right option.
