动词的-ing形式的逻辑主语 A作主语的-ing 形式 -ing 形式作主语时,其逻辑主语对于谈话双方是不言而喻的。 Reading aloud is very helpful. 朗读是很有好处的。(Reading aloud的逻辑主语是泛指任何人,因而无需表达出来)提示:如果作主语的-ing 形式需要自己的逻辑主语时,一般用物主代词或名词所有格(即名词后加s)。 His fathers falling ill worried him greatly. 他父亲生病使他很着急。(his father是falling ill的逻辑主语) Your coming to work with us will be a great encouragement to us. 你来和我们一道工作,对我们是很大的鼓舞。(you是coming to work with us的逻辑主语)B作表语的-ing 形式 -ing 形式作表语时,其逻辑主语往往是句子中的主语,但作表语的-ing 形式也可带有自己的逻辑主语。 What worries me most is Julias staying too late every night. 我担心的是她天天晚上熬夜熬得太迟。(staying too late every night的逻辑主语是Julia) The main problem is your not having practiced a lot. 主要的问题是你缺乏大量的练习。(not having practiced a lot的逻辑主语是you)C作定语的-ing 形式 -ing 形式作定语时,其逻辑主语就是它修饰的名词。 an interesting book 一本有意思的书 = a book that interests its readers a running stream 一条奔流的小溪= a stream that is running 如果-ing形式的逻辑主语是动作的承受者,就要用-ing形式的被动式。 The meeting being held in Beijing now is of great importance. 正在北京召开的会议非常重要。 (逻辑主语the meeting 和“举行”之间的关系是被动的,所以用being heldD作宾语的-ing 形式 -ing 形式作宾语时,其逻辑主语常是句子中的主语。如要明确动作的执行者,也可以在-ing形式前加上名词或代词表示逻辑主语。 I cant imagine Johns giving a speech in front of so many people. 我不能想像约翰会在这么多人前面发言。(John是giving a speech的逻辑主语) He was awakened by someone knocking at the door.他被某人的敲门声吵醒了。(someone是knocking at the door的逻辑主语) The boss understood himhis wanting to leave. 老板明白他为什么要离职。(“他”是wanting to leave逻辑主语)比较: He insisted on doing it himself. 他坚持要自己做。(doing it的逻辑主语是句子的主语“他”) He insisted on my doing it. 他坚持要我做。(doing it的逻辑主语是“我”) Would you mind opening the window 请你把窗子打开好吗?(opening the window的逻辑主语是“你”) Would you mind my opening the window 你介意我把窗子打开吗?(opening the window的逻辑主语是“我”) E作宾语补足语的-ing 形式动词-ing 形式作逻辑主语时,它的逻辑主语就是它前面的宾语。 We often hear her singing this song. 我们经常听见她唱这首歌。(singing this song的逻辑主语是“她”) We often hear this song (being) sung. 我们经常听见这首歌被人唱。(逻辑主语“this song”和宾语补足语“唱”的关系是被动,所以用-ing形式的被动式或-ed分词。) F作状语的动词-ing 形式 1动词的-ing形式作状语时,其逻辑主语一般应与句子的主语保持一致。 Entering the classroom, I found nobody in it. 走进教室,我发现里面没人。(entering的逻辑主语是I,相当于when I entered the classroom, I found nobody in it.)如-ing形式表示的动作不是句中主语发出或承受的,那就是误用。这种无依着的-ing形式,语法上称之为“垂悬分词”。【误】Looking out through the window, the garden was beautiful. (looking out through the window的逻辑主语是the garden,显然不对)【正】Looking out through the window, we saw a beautiful garden. 从窗户看出去,我们看见一个漂亮的花园。【误】Reading the evening newspaper, a dog started barking. (逻辑主语是dog,它不会看晚报)【正】I was reading the evening newspaper when a dog started barking. 我看着晚报的时候,一只狗开始叫起来。 2如不能和句子中的主语保持一致,该-ing形式必须有自己的逻辑主语,通常有名词或代词来担任。 The last bus having gone, we had to walk home. 末班车已经开走了,我们不得不走回家。(having gone的逻辑主语是the last bus,而不是we) Time permitting, the football match will be played on Friday. 天气允许的话,足球赛将在周五举行。(permitting的逻辑主语是time,而不是the football match)注意:高中阶段有一些固定的-ing形式短语,如generally speaking, judging from., considering., talking of., supposing.等,它们的逻辑主语可以和句子的主语不一致。这种-ing短语可当作一个插入语。 Generally speaking, boys are more interested in science than girls.一般说来,男孩比女孩对科学更感兴趣。 Judging from his accent, he must come from Canada. 从他的口音看,他一定来自加拿大。 Considering how poor he was, we decided to let him attend the concert for free. 考虑到他是多么的穷,我们决定让他免费听音乐会。 Supposing it rains what will you do 假使下雨,你会怎么办呢?
