Bonjour tout le monde, Je suis en train de faire mes notions en langues pour le bac. Voici celle sur "espaces et échanges" en anglais. j'aimerais avoir votre avis et une correction si possible. Merci d'avance pour votre aide. The notion of Spaces and Exchanges deals with the geographical and symbolic areas that all societies occupy and the interactions between men and different societies. Our world is built on the exploration and conquest of new spaces. The different cultural, economic, sociological and language interactions have shaped and characterized our modern-day world. Why do so many students go abroad? First of all, I’m going to speak about two forms of exchange that exists in the world. Secondly, I will talk to you about the advantages of this exchange. More and more young people want to go abroad to study but also to discover the world, other cultures and meet new people. Thus, some of these young people decide between secondary school and university to go to a foreign country and make a Gap-Year. They will take advantage this year to travel and get a professional experience. But the gap year requires money to pay for the trip, housing and many other things. That’s why they prefer couchsurfing. In school class, we have studied an article which entitled “Take the couch”. He was published in the Boston Globe eleven years ago. This article presents us the aim of this new form of travelling and how it was created. Indeed, couchsurfing is a website that has existed in different form for just over 10 years. The website provides a platform for members to “surf” on couches by staying as a guest at a host’s home and then to host other travelers. He continues to evolve. We learned in the article that this form of travelling was created on a misunderstanding. Indeed, Casey Fenton sent an e-mail to request accommodation to 1500 Icelanders through the University of Iceland student instead of booking a hotel. Finally, this weekend was the best experience and he decide to create the couchsurfing website for others o take advantage of it. Now, I’d like to discuss about the advantages of this exchange. As we have seen, the gap year and couchsurfing are two examples of trips that students love. Indeed, according to the video we watched during the year, this trip allows them at first to discover a new country and therefore a new culture. Thanks to this experience, they enrich their culture but not only. But that's not all because this experience can be valued by a future employer since being in contact with another environment of life these young people could develop their vision of the world. This brings a lot both professionally and personally because during this year they have been able to improve their level in languages. Indeed, by being in total immersion in a country you are delivered to yourself and must fend for yourself, so it is necessary for you to communicate even if initially you did not have a good level. It is also an opportunity to create friendly ties with people from all over the world. Moreover, with the couchsurfing system you do not have to pay for your accommodation. So you can travel without spending too much. To conclude, I think that so many students go abroad to improve her languages and get an new experience in her life. Personally, I would like to go abroad for doing this kind of travel. I suppose that can bring me a new vision of life and mostly that I can meet some new people with this. I think that this last point is the most important for me because I’d love to meet people from others culture.

Bonjour tout le monde, Je suis en train de préparer mes notions en langues pour le bac et j'aimerai avoir un avis et une correction. Pour l'instant j'ai rédiger la notion "l'idée de progrès" en anglais. Merci d'avance pour votre correction et votre avis!! I am going to talk about the idea of progress. The idea of progress can be defined as an improvement, a development or a change. It can be a technical, scientific or social advance which contributes to making the world a better place. However, the idea of progress is still debate between those who consider that it’s beneficial and those for whom it’s harmful. Now, I propose we look at a question: Does progress always have advantages? To answer this question, I will talk about progress and its advantages. Then I will talk about disadvantages. First of all, I think progress is essential to evolve. History is made of progress and evolution that have allowed the world to be what it’s today. Society is still moving so is language. With the development of new technologies like phones, computers, tablets for example, people are change their means of communication. As we have seen, more and more people use emojis when they write a message. Indeed, according to the text “Emoji is the new language of the future and there’s no going back” which was written by Talia Storm, a girl who is 16 years old emoji are the future. For her emojis are powerful than words and they have many different meanings, too. She thing that they allow us to express our feelings more easily. But they also make a conversation more fun. Furthermore, that’s also what a poll by Viv Evans, a university language Professor reveals. Firstly, eighty per cent of English people use emojis. Then, seventy-two per cent of eighteen to twenty-five age group think it’s easier to express their feelings. So, thanks to emojis, society can change and evolves, they create a new language which make a better life. Emojis are an example of evolution on our society but they have no bad influence on the planet. Indeed, many other examples show that some technological developments have a serious impact on the environment. That’s what we saw on Progress, a painting by Asher B. Durand, a member of the “Hudson River school”. After several hypotheses, we have concluded that the painting shows a sunset on a industrial city which is polluting the atmosphere. More and more of this industrial city are developing in the modern world so they cause the deforestation problem. On the other hand, we saw an article from RTE news, an Irish TV channel. We learned that more and more demonstration was taking place in order to try to warn shoppers to avoid plastic bags. Furthermore, some volunteers decided to put bins near the cash desk so that shoppers can throw away useless packaging. So, plastic can be recycling but today, 300 million tons of plastic are produced globally each year however only 10% is recycled. In the second part of the video, Seamus Clancy, a CEO (Chief Executive Officer) of a recycling plant explains the aim of is company and advantages of what he does. Indeed, he said that since 1997, Repak, is company, has recycled 1 million tons of plastic. Plastic is one of the causes of global warming but it’s also the cause of the disappearance of some animal species like turtles. To conclude, we can say that progress have so many good advantages especially in technical. They make it possible to improve the living conditions of the populations but this to the detriment of the planet. So, progress or good for human evolution but bad for the environment. Personally, I think that we can try to conciliate progress and the safety of the environment.
