【正确答案】：October 23rd, 2022
Dear Sam,
I am writing to ask whether you want to join us as a volunteer at the Tourist Information Center during the summer vacation.
We are to receive more domestic and foreign tourists this summer, including student group visitors organized by elementary and high schools as well as family and individual visitors taking advantage of their summer break. Currently our volunteers have to work more than nine hours a day answering questions and providing assistance. Therefore, we are recruiting volunteers to meet the needs of the rising number of tourists.
The job involves answering questions concerning the local landmarks and places of interest, such as the opening and closing time, ticket policy and transportation options. Some visitors may also ask about popular restaurants serving local foods. Occasionally, visitors in wheelchairs might need a little extra help.
I know you are a people person, and being resourceful, patient and fluent both in English and Chinese, you are exactly the kind of volunteers we are looking for.
Yours,
Li Fei
