Activity 3 Grammar 一、动词-ing形式作定语 1.现在分词形式作定语 (1)单个现在分词作定语时，通常放在所修饰的名词之前。表示现在分词的动作正在进行，分词和所修饰的名词是逻辑上的主动关系。 (2)现在分词短语作定语时，放在所修饰的名词之后。所修饰的名词是现在分词的逻辑主语，现在分词和逻辑主语之间是主动关系。此时相当于一个定语从句。 (3)作定语的及物动词-ing形式为doing和being done。当被修饰的名词与现在分词之间为主动关系时，用doing；当被修饰的名词与现在分词之间为被动关系且表示动作正在进行时，用being done；作定语的不及物动词的现在分词只有doing。 【例句】 ◆He spoke in a low voice in order not to wake the sleeping child. 为了不吵醒那个正在睡觉的孩子，他说话声音很低。 ◆Can you see the star moving in the sky? 你能看见那颗在天上移动的星星吗？ ◆The film being shown in the cinema is exciting. 正在电影院上映的那部电影很令人激动。 【名师点睛】 现在分词作定语，要注意现在分词所表示的动作发生的时间。 一般说来，主要有下列两种情况： (1)表示正在进行的动作(变为定语从句时要用进行时态)。 ① Did you see the girl dancing with your brother. →Did you see the girl who is dancing with your brother. ②The comrades working in the countryside will be back tomorrow. →The comrades who are working in the countryside will be back tomorrow. (2)表示经常性、习惯性动作或现在(当时)的状态(变为定语从句时多用一般现在时态或一般过去时态)。 ①We lived in a room facing the south. →We lived in a room which/that faced the south. ②The factory making these pens is a small one. →The factory which/that makes these pens is a small
