非谓语动词??现在分词与过去分词的区别 现在分词和过去分词在句中都可以用作定语、宾补、状语或表语。下面我们将对它们在句 子中的不同用法加以区分。 ●
  1. 作定语 现在分词作定语表示所修饰词的状态或性质,其被动式表示这个被动的动作正在进行。 过去 分词作定语表示动作已经完成。如: The man standing by the window comes from the South. They don’t like the design of the new bridge being built. ●
  2. 作宾语补足语
现在分词的主动式作宾补表示主动、动作正在进行,被动式表示被动、动作正在进行。而过 去分词作宾补表示被动或完成的动作。 如:You’ll find the topic being discussed everywhere. (现在分词被动式表示动作正在进行,和逻辑主语 topic 之间是动宾关系)I often hear this song sung in English. (过去分词表示动作是被动的,和逻辑主语 song 之间是动宾关系) ●
  3. 作状语 现在分词的一般被动式(being done)用于强调正在进行的被动的动作,表示时间、原因等。 如果强调被动的动作发生在谓语动词之前,则要用现在分词完成被动式(having been done)。过 去分词作状语表示被动,只侧重被动这个事实,而不强调动作。如: Walking through the park I can enjoy the beautiful scene every day. Having answered the question, I was told to sit down. Having been given such a good chance, how could you give it up? Given more time, I would have done the job much better. ●
  4. 作表语 现在分词作表语是对主语进行说明,现在分词的被动式作表语叙述一个被动的动作,不强调 动作正在进行。过去分词作表语表示主语所处的状态。如: What worried the child most was his not being allowed to visit his mother in the hospital. The road was lined on both sides with trees.
