practico:introduction & conclusion of articles

This article is based on the investigation of a news reporter from the BBC, called Rageh Omaar, who was born in the north of Somalia. The aim of Omaar´s investigation was to make a film for the English channel. Through the article the reporter describes the children he interviewed, the reasons why their families sell them, and what are the most common “jobs” these children have.
The world of modern child slavery

Introduction:
Slavery is a word which immediately conjures up very specific images in our minds.
When it is mentioned we tend to think of people, almost always black people; degraded, abused and bound in chains, and we tend to think of such images, and the word slavery itself, as belonging to another era. We do not see slavery as belonging to our world, not as something which is still happening today. Yet the truth is that if William Wilberforce were alive today and he travelled to different parts of the world - not just in Africa, but also in large parts of Asia, the Middle East, South America and even parts of Europe - he would find children living in conditions and circumstances which Wilberforce would understand and which I am sure he would describe as slavery. It is believed there are nearly nine million children around the world today who are enslaved. There are international charters and covenants which try to come to a legal definition of what constitutes slavery. In essence these documents define slavery in the modern world as a situation where a human being and their labour are owned by others, and where that person does not have the freedom to leave and is forced into a life which is exploitative, humiliating and abusive.
Conclusion:
Poverty underlies almost all aspects of the phenomenon of modern child slavery. It is the one issue that most often lies behind the reasons and circumstances they were given up or sold into such conditions. Yet although there has been progress internationally on creating laws and standards aimed at stamping out child slavery, there are still many adults who not only gain from child slavery but believe that they will, in more cases than not, get away with it. Defining what modern slavery is, even finding out the scale of it around the world, is not enough if the practice is not seen to be punished.

In order to introduce the subject of his article, the author appeals to what most of the people in general imagine when they are talked about slavery. The images he makes reference to are many times used by film directors so he counts on our background information to make his statement successful. He also introduces the name of a ----- when he refers to the way in which slavery has spread out, so History is mentioned in a way. The last sentences of the introduction are about how is defined the word slavery now-a-days, and the difficulties that charters and organizations had in order to establish a legal definition to the word itself.
In the conclusion the author recognizes in poverty the most important reason of the selling of children and slavery as its consequence. Therefore he generalizes the main problem of this actual phenomenon. Once again as in his conclusion, Omaar deals with legality, and even though he bounces some positive initiatives from international organizations, he still urges for a quicker and definite solution. While in the introduction of this article slavery is referred to as a word to be defined in legal documents, for the conclusion he takes the same idea, but this time he also evokes to what is to be done in practice in order to stop slavery definitely.
