新概念英语第二册动词的时态课件

动词的时态 Tenses 一般现在时 一般现在时主要用来描述经常出现、反复发生的动作或存在的状态和其他情况。 Every day I go to work on foot. We are all teachers . She works in a big company . We work in the same company. You have a brother, so have I, and she has one, too. 主要用于下面几情况： 1) 描述当前时间内经常出现、反复发生的动作或存在的状态。在这种情景中，句子常带有表示频率的时间状语：always , everyday , often , once a week (month , year , etc.) , sometimes , seldom , usually等等，以表示句中的动作或状态是习惯性的、经常性的。 She doesn't often write to her family, only once a month. I cycle to work every day . It seldom rains here . 2）仅为了描述状态、性质、特征、能力等等。 这里的目的是为了"描述现阶段的动作或状态"，其重点"不是强调动作发生的时间、或进行的状态"。 He can speak five foreign languages . Changjiang River is one of the longest rivers in the world. All my family love football . My sister is always ready to help others . 3) 陈述客观事实、客观真理。 顾名思义，客观的情况是"没有时间概念"的；也"不会在意动作进行的状态"。例如： The sun rises in the east . The earth goes around the sun . Ten minus two is eight. Light travels faster than sound . 4) 一些与travel（旅行）有关的动词和其它少量动词，可用于一般现在时，表示按规定计划安排要发生的动作。这样的动词常见的有：arrive , begin , start , come , close , depart , end , go , leave , open , return , stop等。 The train leaves at 10:05 a.m. The plane from Hainan arrives at 6 p.m. When does our school begin? 1. Here___. A. comes the bus B. the bus comes C. does the bus come D. coming the bus 2. A hunter is a man who _________ animals. A. catch B. catches C. will catch D. was catching A B 3. I _________ ping-pong quite well, but I haven’t had time to play since the new year. A. will play B. have played C. played D. play 4. My teacher told us that Columbus discovered the America in 1492. My teacher told us that Columbus discovers the America. B 一般过去时 主要是用来描述在过去某个时候发生的动作或存在的状态。它也可以用来表示在过去某段时间里经常发生的习惯性动作。这一点在表达意义上与一般现在时相同，只是所在的时间区域不同而已。由于它的主要作用如此，所以在使用一般过去时的句子里常常有一个意义较具体的过去时间状语。这也是它与现在完成时的最大区别之一。 一般过去时由谓语动词的过去式表示，也就是说动词词末要加-ed（除不规则动词外）。常和一般过去时连用的过去时间状语有：last night (week , month , year , century , etc.) , yesterday , the day before yesterday , yesterday
