This will allow the chorus of young and elderly Anglo-Saxons to
assemble on the side stages either side of the seating block, more or less
unseen, ready to take the action further, playing across the horizontal plane.
请问老师,either side of the seating block 前面是不是应该有个 on 或者有个“逗号”?either side of the seating block是对the side stages的补充解释对吧?
谢谢老师!
