美国人怎样表达他们对爱迪生的敬意

托马斯·阿尔瓦·爱迪生获得的发明专利，超过了任何一位美国人。当他1931年离世时，美国人简直不知道究竟怎样才能最充分地表达对他的敬意。

一项建议是，全国熄灯一两分钟，让家庭、街道及工厂的供电全部中断。

这项建议也许会使美国人充分认识到爱迪生及其发明的价值。然而，电对于这个国家来说是太重要了，即使是短暂的停电也会导致全面的混乱。熄灯会造成一片黑暗，这样做不堪设想。[来源:学科网]

在爱迪生安葬的那一天，许多人默默地扭暗了灯光。他们以这种方式，向这位把巨大电力送到全国同胞的手边，从而作出了无与伦比的贡献的人，表示了崇敬之情。

【释疑与评价】

1. 一般过去时被动语态的结构为“主语+ was /were +及物动词的过去分词 (+by+动作的执行者)。

肯定句：主语+ was/were +及物动词的过去分词+其他。

否定句：主语+ was/were not +及物动词的过去分词+其他。一般疑问句：Was/Were +主语+及物动词的过去分词+其他？

2. 主动语态变被动语态应注意的问题。

(1)有些短语动词相当于及物动词，变为被动句时介词或副词不能去掉。

         They put off the meeting because of the weather. 

The meeting was put off because of the weather.  会议因天气的缘故被推迟了。 

(2)含有双宾语的主动句变为被动句时，通常把指“人”的间接宾语变为主语，指“物”的直接宾语保留不变；如果把指“物”的直接宾语变为主语，则在间接宾语前加to或for。 

My aunt gave me an e-dictionary yesterday. →I was given an e-dictionary yesterday.                                    

或→An e-dictionary was given to me yesterday. 

(3)主动句中感官动词see/hear/watch/feel等和使役动词make/let/have等后跟省略to的动词不定式，变为被动语态时应加上不定式符号to。

I saw a heavy man enter the house.  → A heavy man was seen to enter the house. 

(4)系动词、不及物动词或某些短语动词（happen, take place, come true…）没有被动语态。

3. 辨析invent，discover，find，create

invent 指发明、创造出自然界本来不存在的东西，如工具、方法、手段、汽车、电器、等。

discover是“发现”的意思，是指发现原来就有而一直没被发现，如发现电、煤、石油科学真理等。

find的意思是“寻找”，强调找的结果，并不指发现。

create指有目的地把原材料制成新产品，也指创造出原来不存在的或与众不同的事物。

4. be used for 用来做… 此短语中的for是介词，表示用途，后接名词或动词-ing形式。

be used for doing可以转换成 be used to do 的形式。注意used to do sth. 是“过去常常做某事”。

be used as 意为“被用作…”，介词as表示“作为”，其后一般接名词，强调使用的工具及手段。

be used by 意为“被…使用”，介词by后面接动作的执行者（宾语）。

同步练习

用invent, discover,find或create的形式填空。

1.When________ the stream engine（蒸汽机）________?

2. I can’t ________my bike, I’m looking for it.

3. Do you know who________ the plane？

4. He ________quite a number of wonderful characters in his play.

5. 以前农民们用这种机器来收割庄稼。

 This kind of machine___________ ___________ ___________farmers for getting in crops long before.

6. 这些书几年前当作教科书来用。

These books ____________ ____________ ___________ textbooks several years ago.

温馨提示

 1. please v. 使…高兴，使…同意, pleased adj. 指人感到高兴的

       pleasant adj. 指某事或某物令人愉悦,  pleasure n. 愉快，满足，高兴

     2. 被动语态的用法巧记：谁的动作不知道，说出谁做没必要；承受之人需强调，被动语态莫忘了。
