Penjelasan:

What is Present Perfect ?

We usually use the present perfect when referring to things that started in the past and have a connection to the present. The formation of the present perfect is given below.

Has/Have + the past participle of the verb

Let us try to understand this through a simple example.

I have lost my car key.

According to the example, the person had lost the key in the past and were unaware of when it happened and has not been able to find it yet. This means there is a connection to the present because the key is still lost. Another important factor to bear in mind is that we use the present perfect because we are uncertain of the exact time that an incident occurred. For example,

Someone has dropped a pen.

What is Past Simple?

The simple past tense is used for actions that started in the past and ended in the past as well. In the simple past, there is no connection to the present as in the present perfect. The formation of the present perfect is given below.

Verb + ed / irregular verb

Now, let us try to understand the usage of the past simple through an example.

I watched that movie yesterday.

According to the example, the speaker has completed the action of watching the movie in a specific time (yesterday). This is a special feature of the simple past tense as it specifically mentions the time unlike in the present perfect. It refers to something that happened in the past and the action has no connection to the present, hence the past simple has been used. Let us assume that the speaker said:

I have watched that movie many times.
