It isnt raining any more.（2）表示在现在相对较长一段时间内正在进行的动作，但是说话一刻不一定在做的动作Have you heard about Tom? He is building his own house. David is teaching English and learning Chinese in Beijing.这些动作，在说话时并不一定在发生或进行，而是在包括说话的一刹那在内的一段时间内发生、进行的。（3）表示最近的确定的安排Ann is coming tomorrow.Oh, is she? What time is she arriving?At 10:15.Are you meeting her at the station?I cant. Im working tomorrow morning.以上句子也可以用be going to（do）的形式来表示。但是谈论已确定的安排时候，用现在进行时态显得更加自然，除非受到动词的功能的限制。在此，切不可用will，如：Alex is getting married next month. 不能用 will get married.（4）和always 连用表示某种情绪，可能是厌烦也可能是赞扬，如：Tom is always going away for weekends. My husband is always doing homework.  （五）can引导的一般疑问句及回答Can you swim?Can we watch TV now?Can they play football?Can he cook?Yes, we/you/they he can.No, we/you/they/he cant.
