Present Perfect vs. Past Perfect
Have you visited Paris?
Yes, I have visited Paris last year.
This would be a typical answer for an ESL student when studying the English Perfect Tense. Many of them have problems in deciding whether or not they should use specific time. The correct answer here could be any one of these replies. "Yes I have" or "Yes, I have several times" or "Yes I have visited Paris once." When students are introduced to the Past Perfect Tense, they will have a better idea of distinguishing when they should use definite time. Use some ESL grammar games for past perfect tenses in classroom activities to make the concept clearer.
Examples of Specific Time
If we compare any of the replies above to the following sentence, you will observe that there is a marked difference in how we use a specific time.
- I had visited my relatives once in 2005 before I visited them again in 2008.
Once again if we change this to “I have visited my relatives once in 2005"; we can actually feel the awkwardness of this sentence. The past perfect sentence here can also be expressed in the simple past, so the past perfect is optional. We can also say, “I visited my relatives once in 2005 before I visited them again in 2008." This is because when the words "before" or "after" are used in a sentence, they actually tell you what happens first. Note, however, that if the past perfect is not referring to an action at a specific time, it is not optional and must be used.
(Simple Past) She never ate snails before she moved to France. (Not correct)
(Past Perfect) She had never eaten snails before she moved to France. (Correct)
The simple past cannot be used here, because we are not referring to an action at a specific time such as “visiting Paris", but a lack of experience.
In order to clarify the entire above, try teaching some past vs. perfect tense grammar games. Prepare some sentences where your students fill in the blanks with the correct tense of the word in brackets and complete the sentences. After you have corrected them, let the students play at using these sentences in real life communication. Here are some sentences which students can use to role play.
