明晰规则
1.现在完成进行时的构成: has/have+been+现在分词
2.现在完成进行时的基本用法:(1)表示开始于过去某个时间,一直延续到现在,并且会继续进行下去的动作。动词多用延续性动词,并常和all this time、this week、this month、all night、all the morning、recently、“for+一段时间”等状语以及“since+状语(从句)”连用。
(2)表示从过去某时开始到现在这一段时间内动作一再发生。
(3)表示动作刚刚结束,该动作一般不再继续,有时会指出结果。
3.现在完成进行时与现在完成时的区别:现在完成进行时表示动作在迄今为止的一段时间内持续进行并有可能继续进行下去,强调动作的持续性或带有某种感情色彩;现在完成时表示动作已完成,强调动作的结果或影响。
