Language is essentially a means of communication among the members of a society. The purpose of this article is to show the importance of communication skills (listening, speaking, reading and writing skills) in the classroom in order to get a perfect acquisition of the second language. These skills are really connected and it is important to put into practice together and integrate them with the classroom activities. After my experience as assistant lecturer, I have noticed that these skills are very important parts in relation to the acquisition of English, I have also asked my students in order to know their thoughts in relation to my hypothesis, and they assure that these skills need to be developed. Students need to know how to be a good listener or speaker, because if they travel abroad, they are going to communicate through listening and speaking skills but not reading or writing only. For DRC French speakers, listening and speaking English tend to be more complicated than the acquisition of other skills, such as reading or writing, since the former are quite difficult to practice when the students do not live in an English speaking country. It is because of this reason that this article deals with some activities to develop with the adult students in order to develop these skills and show why it is important to be developed and the difficulties the learners have. The need to communicate has been focused on and this need arises and becomes stronger and stronger when one has someone else to communicate with. Communication must take place not only in the classroom but also outside the classroom. The language has to be practiced enough by taking into account those skills.
