5. 分詞與連詞的連用

　　分詞可與各種連詞(如：when, while, once, until, if, unless, though, although, even if, as, as if, as though等)連用。連詞+分詞(短語)的結構在句中作狀語，相當于狀語從句。

　　She’ll get nervous when speaking in public.

　　He went on talking, though continually interrupted.

　　6. 分詞的獨立結構

　　分詞作狀語時，其邏輯主語與句子的主語應該一致;否則，分詞應有自己的邏輯主語，構成分詞的獨立結構。獨立結構一般位于句首，作伴隨狀語以及在科技文章中表示附加說明時，它常位于句末。分詞的獨立結構由名詞、代詞+分詞構成，可以表示時間、原因、條件、方式或伴隨情況等。

　　Weather permitting, the football match will be played on Wednesday.

　　Her son having been sent to school, she began to do some shopping.

　　He returned three days later, his face covered with mud and his clothes torn into pieces.

　　There were two parties yesterday evening, each attended by some students.
