阅读理解

     For five days, Edmonton's Downtown Park is transformed into one huge stage where artists are

able to share their talents, and where people are able to celebrate and enjoy themselves. Since its

beginning in 1980, the Edmonton Folk Music Festival has been commemorating(纪念) the true

feeling of what folk music is all about and that's the traditional togetherness(友爱) that is felt when

people gather to share stories and feelings through song.    

     This year will be the sixth year when volunteer Riedel will be offering up her time to the festival.

"People coming off a busy spring and summer have a moment of relaxation," Riedel said."It's really

easy to relax,  and it's great seeing family and friends have fun together." These families and friends

come from all different kinds of musical tastes. People who take pleasure in Blues are there, so are

people who love Bluegrass. This festival does its best to develop everyone's musical interests.    

     With so many years of experience, the festival has become a welloiled machine, and does whatever

it can to make attendees feel as comfortable as possible. There are free water stations throughout the

venue(举办地)for people to fill up their travel cups. When people buy food, reusable dishes are given

a $2 plate fee, but that is returned when the plate is brought back.      

     The festival has completely sold out of tickets,  and in record time. But with big names such as Van

Morrison and Jakob Dylan,  it's easy to see how that was going to happen. There is no parking area

during the festival, so using the Park & Ride system or Edmonton Transit is highly recommended. A

bike lockup area is provided and will be available Thursday until Sunday one hour before the gates

open until 45 minutes after the gates close.      

     The Edmonton Folk Music Festival begins on Wednesday, Aug. 4 with Van Morrison playing the

special donation fund(基金) concert,  and will finish up on Sunday, Aug. 8.
