PRESENT PERFECT 


 


You can use the Present Perfect to describe your experience. It is like saying, "I have the experience of..." You can also use this tense to say that you have never had a certain experience. The Present Perfect is NOT used to describe a specific event.
Examples:

• I have been to France. This sentence means that you have had the experience of being in France. Maybe you have been there once, or several times.
• I have been to France three times. You can add the number of times at the end of the sentence.

We often use the Present Perfect to talk about change that has happened over a period of time.
Examples:

• You have grown since the last time I saw you.
• The government has become more interested in arts education.

We often use the Present Perfect to list the accomplishments of individuals and humanity. You cannot mention a specific time.
Examples:

• Man has walked on the Moon.
• Our son has learned how to read.

We often use the Present Perfect to say that an action which we expected has not happened. Using the Present Perfect suggests that we are still waiting for the action to happen.
Examples:

• James has not finished his homework yet.

We also use the Present Perfect to talk about several different actions which have occurred in the past at different times. Present Perfect suggests the process is not complete and more actions are possible.
Examples:

• The army has attacked that city five times 
•  

SIMPLE PRESENT







Use the Simple Present to express the idea that an action is repeated or usual. The action can be a habit, a hobby, a daily event, a scheduled event or something that often happens. It can also be something a person often forgets or usually does not do.
Examples:

• I play tennis.
• She does not play tennis.
• Does he play tennis?
• The train leaves every morning at 8 AM.

The Simple Present can also indicate the speaker believes that a fact was true before, is true now, and will be true in the future. It is not important if the speaker is correct about the fact. It is also used to make generalizations about people or things.
Examples:

• Cats like milk.
• Birds do not like milk.

Speakers occasionally use Simple Present to talk about scheduled events in the near future. This is most commonly done when talking about public transportation, but it can be used with other scheduled events as well.
Examples:

• The train leaves tonight at 6 PM.
• The bus does not arrive at 11 AM, it arrives at 11 PM.

Speakers sometimes use the Simple Present to express the idea that an action is happening or is not happening now. This can only be done with Non-Continuous Verbs and certain Mixed Verbs.
Examples:

• I am here now.
• She is not here now.

PASSIVE VOICE

Passive voice is used when the focus is on the action. It is not important or not known, however, who or what is performing the action.

Example: My bike was stolen.

In the example above, the focus is on the fact that my bike was stolen. I do not know, however, who did it.
Sometimes a statement in passive is more polite than active voice, as the following example shows:

Example: A mistake was made.

In this case, I focus on the fact that a mistake was made, but I do not blame anyone (e.g. You have made a mistake.).

Subject + finite form of to be + Past Participle

Example: A letter was written.

When rewriting active sentences in passive voice, note the following:

• the object of the active sentence becomes the subject of the passive sentence
• the finite form of the verb is changed (to be + past participle)
• the subject of the active sentence becomes the object of the passive sentence (or is dropped)

Rewriting an active sentence with two objects in passive voice means that one of the two objects becomes the subject, the other one remains an object. Which object to transform into a subject depends on what you want to put the focus on. Personal Passive simply means that the object of the active sentence becomes the subject of the passive sentence. So every verb that needs an object (transitive verb) can form a personal passive. Example: They build houses. – Houses are built. Verbs without an object (intransitive verb) normally cannot form a personal passive sentence (as there is no object that can become the subject of the passive sentence). If you want to use an intransitive verb in passive voice, you need an impersonal construction – therefore this passive is called Impersonal Passive. Example: he says – it is said Impersonal Passive is not as common in English as in some other languages (e.g. German, Latin). In English, Impersonal Passive is only possible with verbs of perception (e. g. say, think, know). Example: They say that women live longer than men. – It is said that women live longer than men. Although Impersonal Passive is possible here, Personal Passive is more common. Example: They say that women live longer than men. – Women are said to live longer than men. The subject of the subordinate clause (women) goes to the beginning of the sentence; the verb of perception is put into passive voice. The rest of the sentence is added using an infinitive construction with 'to' (certain auxiliary verbs and that are dropped). Sometimes the term Personal Passive is used in English lessons if the indirect object of an active sentence is to become the subject of the passive sentence.
