- The Simple Past tense is used to talk about actions that took place at a specific time in the past.
- The action is over and does not present an evident connection with the present moment.
- Common time expressions used with the Simple Past tense are: <u>yesterday, last week, last month, last years, a couple of days ago, three years ago</u>, etc.
- Example: I saw you at the party last night.
- The Present Perfect tense is used to talk about actions that happened or started to happen in the past and still have a connection with the present moment.
- The Present Perfect implies an "until now". Something has or has not been done, until now.
- It is commonly used with: <u>yet, already, just, and never.</u>
- Time expressions that indicate the present, such as "today" or "this week" are also commonly used with the Present Perfect.
Example: I haven't seen Josh today. What do you think he is up to?
