My name is Talgat, I’m from Kazakhstan. I’m keen on travelling. I’ve already visited some cities in my country. They are Nur-Sultan, Almaty, Karaganda and others. There are beautiful views of mountains and lakes in some of them. Now, I have a list of cities I have never been to but I want to visit them.
The first city is Venice, Italy. There are 118 small islands and 150 canals. People cross the canals by different boats. The most famous type of boat there is called a gondola. The buildings in Venice are very old and attractive.
Another city is New York, USA. New York is one of the largest cities in the world. Its population is over 11 million people. It’s very crowded and noisy. Life in this city is very exciting. There are many places of interest in New York. They are the Statue of Liberty, the United Nations Building, Empire State Building and others.
The next city is Sydney, Australia. It is a pretty and large city. Its main attraction is the Sydney Opera house. It has an amazing shape, similar to sails of a ship. Also, I would visit Bondi Beach, which is a very popular place. Sydney is a very multicultural place. You can see people of all nationalities, like in Kazakhstan.
And the last city in my list is Paris, France. It is a wonderful romantic city where you can see many fascinating things and sights. Visiting the Eiffel Tower is my dream. There are famous museums in Paris as well. The Louver is the first place I want to visit there.
Our world is so big and it is so interesting to travel, to meet new people and to learn new traditions
