当although分句的主语跟主句的主语一致的时候,althgough的主语可以省略,由althgouh+实义动词的ing形式代替. 是不是说, 这种结构里的v.+ing形式不能被视为现在分词? 又回头看了看讲although后面接从句的OG11-09题: 9. Sunspots, vortices of gas associated with strong electromagnetic activity, are visible as dark spots on the surface of the Sun but have never been sighted on the Sun’s poles or equator. (A) are visible as dark spots on the surface of the Sun but have never been sighted on (B) are visible as dark spots that never have been sighted on the surface of the Sun (C) appear on the surface of the Sun as dark spots although never sighted at (D) appear as dark spots on the surface of the Sun, although never having been sighted at (E) appear as dark spots on the Sun’s surface, which have never been sighted on 其中的C项, although never sighted at...其逻辑主语跟主句的主语sunspots也是一致的.... 恳请NN解惑. |
