就是with + 賓語（名詞或代詞）+ 賓補(bǔ)（介詞短語,形容詞,副詞現(xiàn)在分詞,過去分詞,不定式）,是一個(gè)獨(dú)立主格結(jié)構(gòu),在句中做狀語,可表原因,伴隨等.
例句：The teacher came in with a book in his hand.老師手里拿著一本書進(jìn)來了.
With a lot of work to do,I have no time go out with you.(不定 式表將來動(dòng)作)有許多工作要做,我沒時(shí)間和你一起出去.
We found the house easily with the little boy leading the way.(現(xiàn)在分詞表示主動(dòng)動(dòng)作,即分詞所表示的動(dòng)作是由with后的賓語發(fā)出來的)
With all the things she needed bought,she went home happily.(過去分詞表示被動(dòng),with后面的賓語與過去分詞之間是被動(dòng)關(guān)系)
