如果我想说“复习在学习方面起重要作用。”，用play an important role in 造句应该怎么做？
play an important role in 后面是加doing
“芹散复习在学习方面起重要作圆茄用。”嫌腔氏Review plays an important role in learning
Review plays an important role in your study/learning.
in 后面一般加名词或名词隐拍性咐庆词组，所以应该衡携握用v+ing形式。
只接doing，因为in 是介词。
in是介词，后面接动名词
Review plays an important role in learning.
