1In this week's episode of Everyday Grammar, we're going to help you understand the difference between the simple past and the present perfect.
2English learners often confuse these two verb tenses.
3Let's start with an example. Can you tell the difference between these two sentences?
4Sentence one: I saw the movie.
5Sentence two: I have seen the movie.
6Sentence one uses the simple past tense. Sentence two uses the present perfect tense.
7"I saw the movie" and "I have seen the movie" both refer to an action that was finished in the past.
8But there is one important difference: "I saw the movie" suggests that you saw the movie at a specific time in the past.
9"I have seen the movie" suggests that you saw the movie at an unknown time in the past.
10Use the simple past to talk about a finished action that happened at a specific time.
11For example, "I went out with my friends last night."
12The adverb "last night" is not required, but it does help clarify that the event happened at a specific time.
13That's the easy part.
14Now let's talk about the present perfect.
15You form the present perfect by using "have" or "has" followed by the past participle form of the verb.
16For example, "I have graduated from college."
17The present perfect confuses English learners because it refers to a past action.
18It is also called "present perfect" because speakers use it to stress the importance of a past event in the present.
19The sentence "I have graduated from college," emphasizes the present effect of a past event -- graduation. The exact time of the graduation is not important.
20There are four more common situations that require the present perfect.
21First, it can express a repeated action.
22When an action happened more than one time in the past, use the present perfect. For example,
23"I have seen the movie three times."
24Second, it is common to use the present perfect with the words "for" and "since."
25"For" and "since" are adverbs that tell about the duration of an activity.
26They answer the question "how long?" For example,
27"I have studied English for a long time."
28Third, the negative adverb "never" requires the present perfect. You can say,
29"I have never been to France."
30You would not say,
31"I did never go to France."
32Finally, when asking a question in the present perfect, use "ever," as in,
33"Have you ever won the lottery?"
34Here's a tip: pay close attention to adverbs. Adverbs give hints, or clues, about which verb tense you should use.
35A good way to practice the present perfect is to ask an English-speaking friend if he or she has ever done something.
36"Have you ever flown in an airplane?"
37or
38"Have you ever seen the Grand Canyon?"
