现在进行时
一、含义 现在进行时表示目前正在发生的事情或正在进 行的动作。常与now,at the moment,at this time,these days等时间状语连用。
现在进行时通常用于: 1. 表示说话时正在进行的动作。 例如: I Look! They are watching TV. 看!他们正在看电视。 2. 表示目前阶段正在进行(但说话时不一定在进行) 的动作。 例如:I am practising the dance these days. 这几天我一直在练习这个舞蹈。
16. Where is Simon? His mother ____________ is looking (look) for him everywhere. 17. Please turn off the radio. is sleeping (sleep) now. Grandma____________ is playing (play) the guitar 18. Listen! Someone____________ in the next room. Who is that? 19.—____________, your father____________ Is watching (watch) TV, Jim? isn’t is playing —No, he____________. He____________ (play) the computer games. 20. Why____________ you ____________ (stand) are standing here? There is water everywhere.
3. 当有些表示感官知觉的动词词义转变成为表示 动作的动词时可以用现在进行时。 例如: (1) see意为“会见;会晤”,可使用现在进行时。 例如: The class teacher is seeing his parents now. 班主任现在正在会见他的父母。 (2) smell与taste意为“有目的地去嗅/尝”时,亦可 用现在进行时。 例如: She is smelling the flowers (to enjoy the pleasant smell). 她正在闻花香(享受那令人愉快的气味)。
4.现在进行时与一般现在时的区别在于:现在进行 时强调此刻或现阶段正在进行的动作;一般现在 时强调动作的经常和反复,或属于主体本身具有 的特征,实际上这类动作没有时间性。 例如: She is reading a book now. (强调的是此刻正在读书)她现在正在读一本书。 She reads books every night. (强调的是每天晚上都在读书)她每天晚上都会读 书。

7. 以-ie结尾的动词,其现在分词需将-ie变成 -y, 再力口 –ing。 例如: lie→lying tie→tying 8. 以“元音字母+ -y/-w‖结尾的单词,其现在分词 在词尾直接加-ing。 例如: bow→bowing play→playing 9. 动词be的现在分词是being。
二、现在进行时谓语动词的构成方法 1. 现在进行时的语法基本结构是“am/is/are +动 词的现在分词”。 例如:She is dancing.她正在跳舞。 2. 在否定句中,谓语动词为“am/is/are + not +动 词的现在分词 例如:He isn’t sleeping.他没有在睡觉。 3. 构成一般疑问句时,只需把be动词的相应形式 提到主语前,放在句首即可。例如: Is he cooking the dishes now? 他现在在做菜吗? 4. 构成特殊疑问句时,其结构为“特殊疑问词+ am/is/are +主语+动词的现在分词” 例如: What are they doing? 他们在在做什么?
