on the afternoon of Friday 还是 in the afternoon of Friday 哪个对

on the afternoon of Friday 还是 in the afternoon of Friday 哪个对 in the afternoon of Friday还是on Friday afternoon 为什么是on Friday afternoon而不是in the Friday afternoon 请问是in Friday afternoon还是on Friday afternoon? ( )the afternoon of friday.在这个句子中afternoon不是中心词吗?是否用in? They usually played table tennis on Friday afternoon in the I'm very busy on the afternoon of Friday.错哪里了? 是in the afternoon of April 30th 还是 on the afternoon of April 应该是in the afternoon of July 11,还是on the afternoon of July 11 On Friday afternoon,many students are___after a long week of the afternoon of Monday前应该写in还是on We clean the classroom on Friday afternoon.改为一般疑问句
