Being more careful, you can make fewer mistakes. 如果你更细心,你会犯更少的错误。
强调条件时,可以在前面加上unless, once等。如:
You shouldn’t come in unless asked to. 不让你进来你不准进来。
Once losing this chance, you can’t easily find it. 一旦失去这次机会你就很难找回。
二、分词的独立主格结构
分词短语作状语时,其逻辑主语就是句子的主语,否则,就必须在分词前另加上自己的逻辑主语(名词或主格代词)的这个结构叫独立主格结构或分词的复合结构。
1、独立主格结构常放在句首。表示时间、条件、原因时,其作用分别相当于个时间、条件、原因状语从名句。表示伴随方式时,相当于一个并列句。如:
Supper finished (=After supper was finished), we started to discuss the picnic. 吃完晚饭,我们开始讨论野餐的事。
All the tickets having been sold out (=As all the tickets having been sold out), we had to wait for the next week’s show. 所有的票都卖出去了,我们只好等着看下周的演出。
2、表示独立主格结构中的being常省略。如:
The football match (being) over, crowds of people poured out into the steet. 足球赛五结束,从群便涌到大街上。
Nobody (being) in, I didn’t enter the hall. 里面没有人,我没进大厅。
3、表示伴随方式的独立主格结构,有时可用“with+宾语+宾语补足语”的结构来替换。如:
He lay there thinking, his hands behind his head (with his hands behind his head). 他双手放在头下,躺在那里思考着。
The river looks more beautiful, flowers and grass growing on both sides(=with flowers and grass growing on both sides). 这条河看上去更加漂亮,因为两岸长满了鲜花和绿草。
with+宾语+宾语补足语的结构是英语中常见常用的结构,其宾语补足语可以是现在分词、过去分词、不定式、形容词、副词、介词短语等,在句中可作定语,也可作状语,表示原因、方式等。如:
The children looked at us, with their eyes opening wide. 孩子们眼睛睁得大大地看着我。
I would miss the train, with no one to wake me up. 没人叫我,我会错过火车的。
The river with grass and flowers on both sides runs through our schoolyard. 这条两河两岸长满鲜花和绿草正从我们校园穿过。
