（3）表示意向的动词，如hope, wish, expect, think, intend, mean, suppose等，用过去完成时表示“原本……，未能……”，例如：

3．过去完成时的时间状语：before, by, until, when, after, once, as soon as等，例如： By the time he was twelve, Edison had began to make a living by himself.

Tom was disappointed that most of the guests had left when he arrived at the party. By the end of the match，they had kicked two goals and we had kicked four． We had reached the station before ten o'clock． When I got there，you had already started playing． Wang Lin had mended the radio before his brother returned． 四、语态

1. 语态种类：主动语态和被动语态。主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者，也就是动作的对象。一般说来，只有及物动词才有被动语态。汉语往往用“被”、“受”、“给”等词来表示被动意义。 2. 被动语态的形式

英语动词的被动语态由助动词be加及物动词的过去分词构成。助动词be有时态、人称和数的变化，其变化规则与系动词be完全一样。

现以ask为例，将各种人称、数和时态的被动语态的肯定式、否定式及疑问式如表10.17所示。

（1）当我们不知道谁是动作的执行者，或者没有必要指出谁是动作的执行者时，例如： This jacket is made of cotton. 这件夹克是棉布的。

The book was written for children. 这本书是为儿童而写的。

（2）当我们既关心动作的承受者也关心动作的执行者时，用by加动作执行者来表示，例如： Food is needed by every living thing. 食物是每个生物的必需品。 5. 短语动词的被动语态
