			 One common use for the present perfect tense is in 
			showing actions or situations that began in the past and 
			continued until now. There are, however, other uses. 
			Another common one is in showing repeated actions 
			that happened at an unspecified time before now and 
			that are likely to be repeated after now. 
			Examples: 
			I've seen that movie a dozen times. 
			He's been absent twice. 
			They've made a lot of new friends. 
			When the present perfect tense is used to show repeated 
			actions, so far and in / during / over the past / last _____  
			are very common; so are some frequency adverbs. 
			Examples: 
			I've seen that movie a dozen times so far. 
			I've seen that movie a dozen times 
			in the past two years. 
			I've frequently seen that movie. / 
			I've seen that movie frequently. 
			He's been absent twice during the past week. 
			He's often been absent. / 
			He's been absent often. 
			She's made a lot of new friends over the 
			past few days.

						 When the present perfect tense is used in 
						sentences such as those above, the action or 
						situation does not continue, but it is also not  
						considered to be completely finished. If 
						simple past tense is used in sentences 
						such as those above, however, the action or 
						situation is considered to be finished: 
						I saw that movie a dozen times. (finished) 
						I've seen that movie a dozen times. (not finished) 
						He was absent twice. (finished) 
						He's been absent twice. (not finished) 
						She made a lot of new friends. (finished) 
						She's made a lot of new friends. (not finished)
