發(fā)出的，當(dāng)主從句主語相同時，可把從句改為分詞短語）

二、現(xiàn)在分詞作狀語1.現(xiàn)在分詞作狀語時,分詞的邏輯主語必須是72.現(xiàn)在分詞作狀語時,分詞的邏輯主語不是句子的主語時,不能直接用現(xiàn)在分詞作狀語。判斷正誤：①Whensheheardthewords,herfacewentred.()②Hearingthewords,herfacewentred.()（分詞hearing的邏輯主語不是句子的主語

herface發(fā)出的,不能用現(xiàn)在分詞作狀語）

【注意】分詞的邏輯主語不相同時,要用獨立主語，即獨立主格結(jié)構(gòu)。如:Thegirlwaitingforthebus,abirdfellonherhead．=Whenthegirlwaitedforthebus,abirdfellonherhead.√×2.現(xiàn)在分詞作狀語時,分詞的邏輯主語不是句子的√×83.少部分V-ing形式可以充當(dāng)獨立成分，這時句子主語與其無任何語法關(guān)系，不要誤認為是V-ing形式作狀語。如：Judging

from

histone,there'snodoubtheisagainst

it.從他的話音可判斷，毫無疑問他是反對的。常見短語：generally/strictly/exactlyspeaking大體/嚴格/準(zhǔn)確說來judgingfrom/by...根據(jù)……判斷talkingof...談到……considering...考慮，鑒于……supposing(that)．..假設(shè)，假定regarding...關(guān)于……3.少部分V-ing形式可以充當(dāng)獨立成分，這時句子主語與其91)Thechildranthroughtherain,hishairgotwet.________________________________,hishairgotwet.2)Iftimepermits,we'lldoanotherexperiment.
