1、专题九：动词的时态：英语是一个有时态的语言。体现在动词的时态变化。请同学们观察以下句子。第一组：一般现在时动词具有数的变化。即动词原形和三单。be动词有单数和复数的变化。（1） He often takes exercises.（2） Students of the class study very hard every day.（3） The earth moves around the sun.（4） Here are some tips to help you.（5） Time and tide wait for no man.若动作是反复、经常发生的或者描述事实和真理的话反复发生的动作

2、一般会有频率副词结合使用（经常）always/usually/frequently/often/generally/every day(month/year/week)/all the time（有时候）sometimes/occasionally/at times/from time to time/on Sundays（几乎不；很少）hardly/seldom/rarely/once/twice/three times 一般现在时（从不）never（从现在开始）from now on第二组：一般过去时 （1） He finished the work yesterday.（2） I wen

4、Mary will study abroad in the future.（2） I will go to the supermarket tomorrow.（3） Our school will hold a sports-meeting next week.（4） They are going to get married in a year.若动作发生在某个将来的时间 一般将来时will+V原/be going to doin the future, tomorrow, the day after tomorrow, next week/year, in +一段时间（表将来）/one d

5、ay表示趋向行为位移的短暂性动词如come,go,start,begin,leave等常用进行时表将来时。eg.The students are leaving tomorrow. 学生们明天将来离开。表将来be about to do（马上、即将要做某事）/be to do（表计划、安排，含有吩咐、命令、禁止、要求等语气）/be going to do（表示计划、安排或某种迹象）eg.Look at the dark clouds. It is going to be a storm.You are not to bring any mobile communication means in

7、现在进行时/过去进行时现在进行时now, right now,listen, look,smell（常用于句子开头，表示提醒听者注意正在发生的事情）过去进行时动作存在在过去的语境中，并且正在进行。（通过观察其他动词的时态判断语境处于过去还是现在）同学们，我们用一个时间轴来表示以上句子吧！ ago/last/yesterday in the future/next/in+一段时间 过去 现在 将来 动作有频率 一般现在时（常态动作） 正在进行 现在/过去进行时第五组 完成时表持续的动作 （1） Tom has learned English for ten years.（2） By the en

9、 过去时（发生在现在的语境中）小结：英语是一个有时态的语言，体现在动词的时态变化。根据动作发生在什么时候，动词时态进行相应的变化。判断动作的时态标志词即时间状语。（表示动作发生的时间）时间状语分为： 表示具体的某个时间点的状语。一般过去时/现在时/将来时 表示时间段的状语。完成时 若动作从过去持续到现在，并且有可能会持续到将来 现在完成时若动作从（更远的）过去持续到（更近的）过去过去完成时若在过去的语境中，存在两个过去的动作，一个过去的动作发生在另一个过去动作之前，构成过去的过去 过去完成时请同学观察以下时间状语，判断分别用什么时态last year on Sundays in ten yea
