One possible version:
Hi, everyone。Everybody has his dream job. I also have my dream job. My dream is to work for foreign tourists as a tour guide.
Why do I want to be a tour guide? First of all, I‘m an outgoing girl, and I like doing some exciting things. Maybe being a tour guide is the best choice. If I become a tour guide, I can travel all around China, and know more about our country. Then I will tell the foreign tourists about our colorful history. Second, I like making friends. If I work as a tour guide, I can make a lot of friends all over the world. This may be great. Perhaps someday my foreign friends will ask me to visit their countries. I really like to go to their countries to know something about their culture. What’s more, I like singing. Singing English songs is my favorite. I believe I will be popular with foreign tourists. Their trip will be excellent.
Now, I am still a middle sc
hool student. My job now is to work hard in school. Then I’ll go to university to learn something about being a tour guide. I’m sure I can be a qualified tour guide in the future
