参考答案（新东方版）：
For those who first live in a big city, they are confronted with multiple unexpected challenges, which, to some extent, may make or break them. So it is essential to be aware of the challenges.
There are two major challenges for them. For one thing, the fast pace of social and professional life would be a hard bone to chew. It would become a struggle and terrible experience, if they cannot get used to the pace of life and work in big cities. For another, how to build a social network in big cities would be also a difficulty for those who want to start a new life in big cities. Without a social network, they would not have the sense of belonging.
All in all, from what has been discussed above, the two major challenges are common for people struggling in big cities. The awareness of the potential problems and proper adjustment is necessary for all people going to big cities.
