[00:00.12]section 2.
[00:02.68]you will part of a radio programme about the opening of a new local sports shop.
[00:09.32]first you have some time to look at questions 11 to 16.
[00:39.64]now listen carefully and answer questions 11 to 16.
[00:48.24]now we go to Jane who is going to tell us about what's happening in town this weekend.
[00:52.24]right,thanks Andrew,
[00:53.92]and now on to what's new,
[00:56.48]and do we really need yet another sports shop in Bradcaster?
[01:01.24]well,most of you probably know Sports World-
[01:04.44]the branch of a Danish sports goods company that opened a few years ago-
[01:09.04]it's attracted a lot of custom,
[01:11.36]and so the company has now decided to open another branch in the area.
[01:16.60]it's going to be in the shopping centre to the west of Bradcaster,
[01:20.44]so that will be good news for all of you who've found the original shop in the north of the town hard to get to.
[01:27.12]i was invited to a special preview
[01:29.60]and i can promise you,this is the ultimate in sports retailing.
