1 . Istanbul is the biggest city of Turkey.

2. I usually spend my summer holidays at my parents' home. I love summer holidays because I don't have to wake up early and I can do whatever I want. I help my parents with housework, for example, I do the shopping and  help my mum to cook, but I also have a lot of spare time, so I hang out with my friends or watch TV, or surf the Internet and chat with my friends on social networks and messengers.

2. Life in big cities is faster and more stressful than life in the countryside. Life in villages is quieter and slower, but it is more boring than life in a city.

2. Nowadays we can see writings or paintings on walls almost in every city. It is great when there are 'graffiti zones' where artists are allowed to draw and paint on walls, but unfortunately there are people who paint on buses and trains, bus-stops and public or private property, which is considered vandalism. Some graffiti artists create great pictures that make cities look better, and such pictures can be called street art.

2. There are a lot of healthy habits that can help us live a longer and better life. First of all, we should stay active, play some active games or walk regularly.

Another important healthy habit is getting enough sleep.

2. It is great to have a pet. Pets make our life less stressful. When we give our pets love and attention, it makes us feel important and useful. Pets are very good friends. They love us and help us stay healthy. For example, people who own a dog have to walk more.

2. People must be friendly and kind to animals. If you have a pet, you should take care of it and treat it as a member of your family, not like a toy. Animals can't talk, but they can feel and they know when people are friendly or hostile.
