人教2003课标版《Using LanguageⅡ》精品PPT课件优质课下载
特点：
分词前没有主语
如何判断？→首先看分词前或者空格前有无主语，再找主句。
如: A rich New Yorker, died in 1919,_____ ( leave) his house ,furniture and art collection to the American people.page6 第二行
二. 如何判断是考分词作状语
leaving
解题思路指导：
看主句的主语和括号里所给的动词构成什么样的关系（主动关系/ 被动关系）
1. ______ (see) from the space, we can find that the earth is very beautiful.
2. _______ (see) from the space, the earth is very beautiful.
例句呈现
__
Seeing
_____
Seen
主句的主语和所给的动词构成主动关系--------- 现在分词
主句的主语和所给的动词构成被动关系--------- 过去分词
三、常考形式
一. 一般式:
1.Arriving at a strange-looking house, he showed me into a large, bright clean room.
2. Introduced into the market, the goods sell well.
二. 词组式: ( be + V-ed.+介词) 做题时只需去掉be即可.
Worried about the journey, I was unsettled for the first few days.此类短语有：be based on/ be concerned about/ be worried about/ be satisfied with…
三. Having done 式:
Having worked hard all day, I went to bed early.
