Asked what had happened, he lowered his head. = When he was asked what had happened, he lowered his head. 2) 原因狀語 Born into a poor family, he had only two years of schooling. =As he was born into a poor family, he had only two years of schooling. Moved by the story, they decided to help her. =Because they were moved by the story, they decided to help her. 3)條件狀語 Given more time, we are sure to finish it. =If we are given more time, we are sure to finish it. Compared with other professors, she is an excellent speaker.=If she is compared with other professors, she is an excellent speaker. 4)讓步狀語 Laughed at by everybody, he had my sympathy. =Though he was laughed at by everybody, he had my sympathy. Defeated by his opponent, he still is a hero in my heart = Even though he was defeated by his opponent, he still is a hero in my heart. 5)伴隨狀語 The boy sat at the table buried in his homework. = The boy sat at the table and he was buried in his homework. The girl lay in bed lost in thought. = The girl lay in bed and she was lost in thought.I will spend the night locked(lock) in your room. She left the restaurant, disappointed (disappoint) with the bad service.Step 2.1.過去分詞作狀語時(shí)，它的邏輯主語為句子的主語，且與邏輯主語之間為被動(dòng)關(guān)系。Whenaskedwhyhecamehere,theboykeptsilent.當(dāng)那男孩被問到為何來這里時(shí)他沉默不語。Bornandbroughtupinthecountryside,hewasinterestedinbiology.由于在農(nóng)村出生并長大，他對生物很感興趣。2.現(xiàn)在分詞與過去分詞的區(qū)別(1)語態(tài)上的不同現(xiàn)在分詞表示主動(dòng)的意思，而過去分詞多數(shù)由及物動(dòng)詞變來，表示被動(dòng)的意思。Iheardsomeoneopeningthedoor.我聽見有人在開門。Iheardthedooropened.我聽見門開了。（2）個(gè)別的過去分詞（多數(shù)是一些不及物動(dòng)詞）并不表示被動(dòng)而表示完成的意思。fallenleaves落葉theexplodedbomb爆炸了的炸彈departedfriends離去的朋友(3)時(shí)間關(guān)系上不同現(xiàn)在分詞所表示的動(dòng)作通常正在進(jìn)行，而過去分詞所表示的動(dòng)作往往已經(jīng)完成。boilingwater正在沸騰的水boiledwater已經(jīng)煮沸了的水developingcountry發(fā)展中國家developedcountry發(fā)達(dá)國家thefallingleaves正在飄落的葉子thefallenleaves落葉（已經(jīng)落在地上）(4)作表語時(shí)，過去分詞通常表示主語所處的狀態(tài)或感受，而現(xiàn)在分詞作表語多表示主語所具有的特征Hearingthenews,wefeltverysurprised.聽到這個(gè)消息，我們感到非常驚訝。Thenewsisverysurprising.這個(gè)消息很令人驚訝。英語中此類詞還有如下：amusing,amused;disappointing,disappointed;exciting,excited;puzzling,puzzled;satisfying,satisfied;pleasing,pleased;interesting,interested;tiring,tired;worrying,worried;astonishing,astonished;encouraging,encouraged.3.非謂語動(dòng)詞的被動(dòng)式作定語的3種形式。thebridgetobebuilt將要建造的橋（表示將來的動(dòng)作）thebridgebeingbuilt正在建造的橋（表示被動(dòng)及正在進(jìn)行的動(dòng)作）thebridgebuilt建好的橋（表示被動(dòng)及完成的動(dòng)作）Step 3 Homework一、單項(xiàng)填空 1.
