The present perfect and past simple The present perfect tense is used to refer to an action that happened at sometime before now. This action may have finished by now, or still taking place at present. Usually it is not important when, the focus is on the result of the action. In the Present Perfect tense, we look from now to the past to express a relationship between the past and present. Form: has/have + past participle verb Example: - I have already completed two courses in Quantum Physics. Comment: this means that I started studying Quantum physics before now (sometime in the past), but it is not known when exactly. You can use the following words with the present perfect: Since, for, already, just, recently, (since + time in the past)

The Past Simple tense is used to express a completed action at specific time in the past (anytime before now). The action is finished and no longer is taking place. Form: Verb 2, irregular verbs have different forms than regular verbs. Regular verbs end with -ed Examples: - Sara bought a house in Palm Beach last summer. Comment: the action of ‘buying’ started and finished at specific time in the past (last summer). You can use the following words with the Past Simple: ago, yesterday, ago, before, last (week, summer, year, Eid, Christmas, October, etc…)

Voice errors “Voice” is the term used to describe the relation of the subject to the action that is expressed in the verb. There are two voices: active and passive. The subjective of an active verb is the doer of the action, while the subject of the passive verb is the receiver of the action, and the doer is often placed in a propositional phrase after the passive verb. Examples Active: Ali (s) ate (v) an apple (o). The subject here “Ali” is the doer of the action “eat” Passive: An apple was eaten by Ali. The subject here “An apple” is the receiver of the action, and the doer is introduced in with by + the doer.
