21、volumes, the third one to come out next month.He came into the classroom, book in hand.2. 分詞做狀語 過去分詞常用作狀語，修飾謂語，大多說明動作發(fā)生的背景或情況，表示時(shí)間、條件、原因、伴隨情況等。 一般說來，這一結(jié)構(gòu)的邏輯主語是主句的主語。Asked why he was late, he went red.Given more time, we could have done it better.3. 分詞做狀語與獨(dú)立主格結(jié)構(gòu)（懸垂結(jié)構(gòu)）做狀語的區(qū)別 分詞與獨(dú)立主格均可作狀語。但分詞做狀語時(shí)，它的邏輯主

22、語就是句子的主語；而獨(dú)立主格結(jié)構(gòu)做狀語時(shí)，前面的名（代）詞就是這個(gè)結(jié)構(gòu)的邏輯上的主語，它和句子的主語不保持一致性。如：Seen from the sky, the mountain is very small.Everything considered, I prefer the first plan.4. 英語中有一部分分詞短語，它獨(dú)立存在，沒有自己的邏輯主語。這些分詞短語已成為固定的習(xí)慣用語，常被看做句子的插入語，常見的有：generally speakingstrictly(honestly/frankly/roughly/broadly) speakingconsideringjudging from/bytalking all/everything into consideration5. 現(xiàn)在分詞和過去分詞的區(qū)別1) 語態(tài)上不同：現(xiàn)在
