1.(2011年高考浙江卷)Bats are surprisingly long-lived creatures,some ________ a life span of around 20 years.
A.having
B.had
C.have
D.to have
解析:选A。考查非谓语动词。句意:真想不到,蝙蝠竟是长寿生物,有些蝙蝠的寿命长达20年。结合语意和句子结构可知,此处为独立主格结构,having的逻辑主语是前面的some。2.(2010年高考山东卷)The living room is clean and tidy,with a dining table already ________for a meal to be cooked.
A.laid
B.laying
C.to lay
D.being laid
解析:选A。考查非谓语动词。句意:客厅既干净又整洁,已摆好了餐桌准备做饭。“with+名词/代词+过去分词”为with的复合结构,a dining table和lay是被动关系,故用过去分词形式。3.—Come on,please give me some ideas about the project.
—Sorry.With so much work ________my mind,I almost break down.
A.filled B.filling
C.to fill D.being filled
解析:选B。答语句意:对不起,脑子里装着这么多工作,我几乎要崩溃了。work与fill为主动关系,且动作不表示将要发生,故用现在分词作宾补。课堂互动探究独立主格
规则展示
一、独立主格的定义
独立主格,又叫独立结构。它没有主语和谓语,只有逻辑上的主语,因此,它在句法上不是句子,而是一个独立于句子成分之外的独特结构形式。独立主格结构可置于句首、句尾,常用逗号与主句隔开。独立主格结构可分为两部分,一部分是名词或代词
(主格),起着逻辑主语的作用;另一部分由形容词、副词、名词、分词、不定式、介词短语等构成,表示前面名词或代词的状态、状况或动作。【注意】 在名词+介词短语的独立结构中,如果逻辑主语与介词短语中名词都是单数名词,在这些名词前习惯上不用冠词。
He was standing there,pipe in mouth.
他站在那里,嘴里叼了一根烟管。
He stood under a tree,hand in pocket.
他站在树下,手放在口袋里。
如与with连用,名词前需加冠词。
He was standing there,with a pipe in his mouth.二、with的复合结构
“with的复合结构”与独立主格结构相近,二者经常可以互换,with复合结构常在句中作状语,有时也可以作定语。规则运用
1.The meeting ________over,he went to pick up his son directly.
A.to be
B.is
C.was
D.being
解析:选D。由句中逗号可知,第一部分不能以句子形式出现,排除B、C;由语境可知“会议结束了,他就直接去接儿子了”,排除A,选用D形成独立主格,此时,因逻辑主语是名词the meeting,being还可省略。2.Everything ________into consideration, they ought to have another chance.
A.to take
B.taken
C.to be taken
D.taking
解析:选B。根据句子结构可知前半部分作状语,everything和take之间是被动关系,排除A和D两项,由句意“考虑到所有的事情,他们应该还有一次机会”,可知动作已经完成。排除C项。3.I send you 100 dollars today,the rest ________in a year.
A.follows
B.followed
C.to follow
D.to be followed
解析:选C。由in a year可知动作尚未发生,可排除A、B两项;the rest与follow之间是主动关系,故D项错误;不定式表示将要发生的事,故C项正确。4.With so many trees and flowers ________, our school campus looks like a beautiful garden.
A.planted
B.to be planted
C.planting
D.being planted
解析:选A。句意:因为种了很多树和花,我们的校园看起来像一个美丽的花园。trees and flowers与plant之间是被动关系,且动作已经发生了,故用过去分词作补语。5.The children were happily making a snowman,________with cold.
A.their faces turned red
B.their faces were red
C.their faces red
D.their faces to be red
解析:选C。句意:孩子们正欢快地堆着雪人,他们的脸都冻红了。此处为“名词+形容词”构成的独立主格结构作状语。逗号不能连接两个独立的句子,故排除A、B项。1.likely

likely,possible,probable
