This special pen was invented by Liu Jie. It has three colors and is used for taking notes quickly. It is very useful if you have a lot to write down. The pen comes with a microchip that can store a list of common words that you will use. You can program the words you will use often into the microchip’s memory, then assign a short form to each word.

语法复习
一般过去时的被动语态
一、一般过去时被动语态的用法
一般过去时被动语态表示过去经常性、习惯性的被动动作或过去某一时刻发生的被动性动作。其结构为：主语(动作承受者) + was / were + 过去分词(+ by + 动作发出者)构成,其否定形式was/were后加not。
如：I was taught by Miss Zhao last year.
Those letters were written by a famous writer.
【注意】被动语态还可用于：强调动作的承受者，而不强调动作的执行者。
如：The window was broken by Mike.
This book was written by him.
二、主动语态变被动语态的方法
(1)把主动语态的宾语变为被动语态的主语。
(2)把谓语变成被动结构(be＋过去分词) (根据被动语态句子里的主语的人称和数，以及原来主动语态句子中动词的时态来决定be的形式)。
语法复习
(3)把主动语态中的主语放在介词by之后作宾语,将主格改为宾格。
All the people (主语：动作的发出者)laughed at him（宾语：动作的承受者）.
He（主语：动作的发出者）was laughed at by all the people.（宾语：动作的承受者）
