热点考查内容如下： 

一． 确定分词形式 

分词作状语时，通常放在句首，并且用逗号与主句隔开。同时，分词作状语时其逻辑主语与主句主语应保持一致，也就是说在确定选择现在分词还是过去分词时，要判断主句主语与分词中心词的关系。如果句子的主语是动词-ing形式所表示的动作的发出者（即表主动或正在进行），分词形式选用现在分词；如果句子的主语是动词-ed形式所表示的动作的承受者时（即表被动或完成），分词形式选用过去分词。 

例：1, _______, I stretched my hand out for it. 

A. I saw the book I wanted on the shell      B. The book I wanted was on the shell

C. Seeing the book lying across the desk     D. Lying on the desk 

分析：分词作状语时，其逻辑主语应与句子的主语一致。根据这一原则，可知句子的主语I只能与see保持一致。 如果选A, 该句中没有连词，没能构成并列句和主从复合句，此时要选用非谓语动词形式。所以选C 

2, Seen from the hill, the park looks very beautiful. 

分析：“Seen from the hill” 是过去分词作状语。分词作状语时，其逻辑主语应与句子的主语一致。根据这一原则，可知，“the park”是“Seen from the hill”的逻辑主语，它们之间表示被动关系，所以分词形式用seen. 

二．确立句子主语可能是谁 

确立句子主语可能是谁时，仍然遵循分词作状语时其逻辑主语与主句主语应保持一致的原则。反过来要根据分词形式确立句子主语。 

例：Having been attacked by terrorists,  _________. 

A. doctors came to their rescue         B. the tall building collapsed 

C. an emergency measure was taken     D. warning were given to tourists 

分析: 本题仍考查非谓语动词的用法。句中“Having been attacked by terrorists”是现在分词作状语。分词作状语时，其逻辑主语应与句子的主语一致。根据这一原则，可知“受攻击”的应是“the tall building”, 即“Having been attacked”的逻辑主语是“the tall building”.句意为“大楼因为受到恐怖分子的袭击而倒塌”. 答案: B 

三．独立主格结构 

分词作状语时其逻辑主语与主句主语应保持一致，但当分词逻辑主语与主语不一致时，分词要有自己独立的逻辑主语，这种主语常常是名词或代词，置于动词-ing形式或动词-ed形式之前。这种名词/代词+动词-ing/动词-ed结构在语法上被称为独立主格结构。此时分词形式的选择取决于名词/代词与v-ing/v-ed形式所表示动作的逻辑关系，如果它们之间表示主动或分词动作正在进行，选择现在分词，如果它们之间表示被动或完成，选择过去分词。 

 1, 名词/代词+动词-ing 

例：Spring coming on, the trees turned green. 

2，名词/代词+动词-ed 

 例：The question settled, they felt released.  

3，with/without+名词/代词+动词-ing/-ed 

例：With the tree grown tall, we get more shade. 

Our school looks beautiful with the flowers coming out. 

The battle was over without a shot being fired. 

四．分词作状语时，相当于一个状语从句。 

例：______weight, the doctor has warned me to keep off sugar. 

A. I’m putting on      B. Having put on   C. As I’m gaining     D. To gain 

分析：在并列句和主从复合句中, 逗号只起分隔作用, 前后两部分的逻辑关系必须使用连接词来表达; 否则要使用非谓语动词. 该题中B， C两项是非谓语动词作状语, 但其逻辑主语与主句主语不一致, 所以只能使用连接词来表达前后两部分的逻辑关系. 答案: C 

五．现在分词和过去分词作独立成分 

英语中一些特殊的分词可用作独立成分，不需要逻辑主语。这种无依着动词形式结构已经成为固定用法。 

常见的不需要逻辑主语的动词-ing/-ed形式结构: 

Considering (that)…考虑到 

supposing (that)… 如果…… 

generally speaking  一般说来 

frankly speaking  坦白说 

Judging from… 从…判断 

talking of…     说到…… 

Concerning…     关于 

setting aside...    除开…… 

Coming to…      谈到 ……    

allowing for...    考虑到…… 

Proving/provided (that)…假定 supposing/suppose (that)…假如…… 

Seeing (that)… 既然 ……          

given (that)…    假设；如果；考虑到 

put frankly   坦白地说                 

taken as a whole  总的说来 

例：1. Put frankly, I don’t agree with what he said. 

坦白地说，我不同意他说的话。 

2. Given the general state of his health, it may take him a while to recover from the operation.  

考虑到他的一般身体状况，他手术后恢复过来可能需要一段时间。 

3. Supposing he is ill, who will do the work? 

假如他病了，谁来做这工作呢？
