Learning about Language教学设计第二课时

M8U4 Pygmalion Period Three-Learning about language Grammar---V.-ed (Revision) 一、教学目的

根据学生实际情况，在尽可能贴近真实的语境中，学习动词过去分词作状语的用法。经过本课学习，学生能够懂得：

1、过去分词(v.-ed)(短语)作状语，表示谓语动作发生的时间、原因、条件、让步、伴随情况等，相当于一个状语从句。

2、过去分词的逻辑主语与主句的主语一定是保持一致的。

3、过去分词与主句主语之间为被动的关系；若分词与主句主语之间为主动的关系，则要用现在分词(V.-ing)作状语。

4、分词前边可以加when, if, unless, once, although等连词，构成“连词+分词”形式

作状语。

Notice 2: 有些过去分词（短语）源于系表结构，作状语时不表动作而表状态。

moved/pleased/disappointed/worried…

be dressed in be seated

be prepared for be lost in沉浸在

be determined to do be devoted to 致力于

be supposed to 应该

be tired of 厌烦

be absorbed in be located in位于

be buried in专心于

be born in…

be compared with be occupied in忙于…

Practice2): (1)

___________in deep thought, he didn’t hear the sound. (absorb) (2)

______

Fill in the blanks: lose 正确形式填空

1)

He sat there,

__________ in thought.

2)

He sat there, __________ himself in thought.

学生总结：

Notice 3: 过去分词作状语与现在分词作状语的区别在于: 过去分词与句子主语构成动宾关系, 而现在分词与句子主语构成主谓关系。

Practice 3)

T or F: Seen from the tower, our city looks more beautiful. (T) Seen from the top of the tower, we can get a wonderful view of our city. (F)

3)_______________(examine) carefully, the patient was sent to the operating room.

4)_________________(show) around the lab, we were taken to see the library. 学生总结：

Notice 4: 若非谓语动词的动作先于谓语动词发生，其用完成时的结构Having done 表主动，Having been done 表被动。

3.

分词作状语记忆口诀: 分词作状语，主语是问题。

逗号前后两动作，共用一主语。

主语找出后，再来判关系。

主动被动要分清，形式要牢记。

having done 表先后，千万要牢记。

Purpose: To help students have the clear idea about the usage of the V.ed

4.

因，伴随，条件，让步等。
