Explanation:
The present perfect tense is the tense we use to talk about events that happened in the past but have present consequences. There are two types of this tense:
- The present perfect simple - used to talk about completed actions that have an influence on the present. The emphasis is on the result of the action.
- The present perfect continuous - used to talk about activities that started in the past and may continue in the present. The emphasis is on the activity itself.

SIMPLE SENTENCE: A simple sentence is one which is made up of only one independent clause; it has a single subject and a verb. A simple sentence can stand alone.
COMPOUND SENTENCE: A compound sentence is a sentence that has two or more independent clauses which are joined together by a coordinator such as for, and, but, etc.
Note that an independent clause is a sentence that can stand alone because it contains a subject, an action and a complete thought. A dependent clause refers to a sentence that can not stand on its own, that is, it does not express a complete thought.
COMPLEX SENTENCE: Is a sentence that combines one independent clause with at least one dependent clause.
COMPOUND COMPLEX SENTENCE: This is a type of sentence that is made up of two independent clauses and one or more dependent clauses.
