The present perfect tense

FORM:

It forms with HAVE/HAS + PAST PARTICIPLE.
-Example: I have finished my homework.

The present perfect of the regular verbs it forms adding –ed to the infinitive
-Examples: walk-->walked, listen-->listened...

USE:

To speak about past actions whose results or consequences still in the present.
-Example: He hasn’t eaten anything. He is very hungry.

To speak about actions just finished we use the past simple with the adverb just between the auxiliary and the participle.
-Example: We’ve just had an accident.

To speak about who started in the past and who’s last in the present yet and probably still in the future. To refer at the last of the action we use the prepositions for and since.
•For refers to a period on time (minutes, hours, months, years, etc).
-Example: I’ve been here for thirty minutes.

•Since refers to a moment on time who started the action and it is followed of an oral expression.
-Example: I’ve been here since 3:30 p.m.

To ask about facts or actions that haven’t finished we use the adverbial phrase: How long...?
-Example: How long have you lived in Madrid?

To refer to an action that happened in the past and who have finished.
-Example: She hasn’t visited El Prado.

With the past perfect tense we can use indefinite time adverbs to be more necessary: ever, never, already, yet and still.
•Ever: it uses in interrogative and negative orations.
-Example: Have you ever been to Argentina?

•Never: it uses in negative orations always when the verb isn’t negative.
-Example: No, I have never been to Argentina.

•Already: it uses in affirmative orations to say that the action have happened yet. It goes after the past participle or at the end of the phrase.
-Example: I’ve already seen the film / I’ve seen the film already.

•Yet: it uses in interrogative orations to ask if the action has happened yet. It goes at the end of the phrase.
-Example: Have you finished that exercise yet?

•Still: also goes in negative orations to say that the actions haven’t happened yet. Still is more efficient than yet, and it goes before the auxiliary have/has.
-Example: We haven’t eaten lunch yet.

Problems around the world

THE THIRD WORLD: Some time ago, nobody knows why, the world was divided into two halves with very bad equitable distribution, since then there is what is known as "Third World". This part of the world is mostly in Africa, very high level of deaths per minute, and trying every day to continue with life, which for him people who live there is very difficult. Should not be allowed to, which is the developed world (in some sense), this will happen. We complain of lack of research to get an antidote to any illness, but in the Third World by one child dies per minute; we protest by having more technical or technological innovations being there, there is no drinking water. I wish I could do something to remedy all this, but one person is impossible to do something like saving an entire continent. I think that the suffering of the Third World, is the clearest example of the global differences, some people have a lot, and others NOTHING.

MINIMUM DUTIES: Any person who belongs to a society such as ours has a general right to all, and that is the vote to express themselves freely and choose the party that will govern their country. In the Third World, for example, people don't stand out for anything important, just because it does not have anything or anyone to help them enough, they need help and at least things like drinking water, food, and above all the right to have someone listen to them and to speak for them, that many are for some very basic needs, the appearance of someone to speak for them and represent them in a developed society would be the minimum right that could have people living in these countries. These countries are not allowed to leave their situation for many things, but above all, by the differences that separate us, surely can never escape, which hopefully that will not be the case.
DISCRIMINATION SOCIAL: Whether people are saying that in this country we are all equal, often differs between men and women. In this century has changed a lot in terms of how society was before. Women now work with more influence. In society, there is still a negative sentiment against the working women, although in many cases is people with a 'closed mind'. In countries like China don't want the women do not want it, I guess it will be because there practicing religion says that the woman is totally unnecessary in society, have recently been discovered cases in which young girls were selling, in carrying suitcases. This surprises me a lot, because we are all human beings and we have the greatest right in the world to live. Fortunately we are thinking about every day we in favor of a woman who: has the same rights as a man, you have the same powers to exercise work, but above all bear in mind always that we are equal.

IMMIGRATION: There is so much difference between third world countries and developed that there is a wave of people who emigrate to other countries to seek opportunities to be able to live well, and sometimes survive. I don’t understand the people who complain that there are foreigners in their country, saying that they take away their jobs, their money and their living space, and not, I can’t understand people who say that. If the people who say these things will put into the shoes of those who migrate to more developed countries, I am sure that would change his mind. They don’t come to take away anything, come to live, as people who are.
THINKING AND FREE EXPRESSION: On many occasions man feels inhibited and forced at times to think what someone dictate, I believe that any human being with the power to reason has the right to think, feel and react at times on his own intuition , or simply do what they think is most appropriate. This isn't what people have in the Third World. This is what's left for immigrants to be able to express themselves and discover that could be developed in their country of origin. The percentage of deaths is closely linked sometimes that nobody is doing anything to prevent this. The discrimination against women, it is clear what their comparison and similarity to the lack of expression and free thought. People have the need to keep some differences, which are not in all respects are beneficial to the progress of this society. We all understand that the world has formed depending on the direction in which we, is a progressive but discriminatory, since not all parts of the world are developing well.

GREENHOUSE EFFECTS AND ITS CONSEQUENCES: There are too many people in the earth and this fact leads to a disaster. The reasons are obvious: too many people --> we have to produce tons of food --> the use of harmful methods to improve the harvest (pesticides, fertilizers, DDTS…) and the continuous use of new lands for crops --> pollution of the ground and water --> as we are too many people --> we have too many cars --> we produce too much smog, smokes, sprays…--> the dangerous cut of trees --> dessertization --> GREENHOUSE EFFECTS. The consequences of this effect are: the gobal warming of the earth, the ozone layer, dessertization, etc. The ozone lawyer provokes a global warming of the Earth. At the same time, this warming leads to the melting of the poles. We can stop this, but anybody do nothing.
