Does the Green Youth Olympic Games focus on scientific and technological renewal or concept renewal?

I am looking forward to the Youth Olympic Games.

In 20 10, when it was announced on TV that "the second Youth Olympic Games will be held in Nanjing in 20 14", the whole family was boiling, but I was not so happy and excited because I felt that the Youth Olympic Games was too far away from me.

First of all, it is 20 10, but the Youth Olympic Games is 20 14, and the interval is too long. Secondly, I was only nine years old that year, and the age at which I could participate in the Youth Olympic Games was 14, which was not suitable for people who participated in the competition. However, several recent events around me have changed my mind and I feel that the Youth Olympic Games is not far from me.

In the city, in order to welcome the Youth Olympic Games, people tore down the iron fence separating the automobile lane from the bicycle lane and replaced it with beautiful flower beds. In order to cooperate with the Youth Olympic Games, Metro Lines 3 and 4 started ahead of schedule.

Slogans about the Youth Olympic Games can be seen everywhere on campus: "Share Youth, Build the Future" and "Grow with the Youth Olympic Games" ...

On TV, news about the Youth Olympic Games is everywhere. Let's keep an eye on the progress of the Youth Olympic Games. A question-and-answer activity about the knowledge of the Youth Olympic Games was held on the Internet. Everyone can participate in it and learn more about the Youth Olympic Games.

YOG, come on, I'm looking forward to it. ...
