,spear points ..., 是插入成分做clovis points 的同位结构起解释说明作用 (C) Named for the New Mexico site where they have been first discovered in 1932, Clovis points, spear points of longitudinal grooves chipped onto the faces, have been found all over North America. C选项改变了句子中心,把原来的主从关系颠倒了 同时省去了although,破坏了原来的让步关系 最致命的还是时态问题 have been first discovered in 1932时态错,in 1932 应该用过去时 -- by 会员 sorcerer (2011/4/9 23:03:58)
同学,那你看B和D捏? B是不是Although后面接的成分和内容不对,还有and也用的不合适? D中"Spear...faces"能看作是逻辑主语吗? |
