Actually, watching TV news on a daily basis can help your learning and overall comprehension of a foreign language. I used to follow my TV News strategy when learning Spanish. I started with 24Horas and their Noticias (the link can be found online). At first it was just hard to catch up with all the information. To be honest with you, during the first week I could barely understand a few words, but with time when the level of my vocabulary and grammar knowledge increased I could grasp more.
While watching we will always hear more than we can really understand (at least in the very beginning). You can deal with it by watching the entire news broadcast and then come back to those bits that were difficult to understand to watch them again. Don’t give up if the news pieces appear to be presented in a fast motion. This is very common for Spanish and Italian news as the presenters have the tendency to speak real fast. If you just begin to watch the news attempt to answer some basic questions such as for instance when, where, who, why and how that concern the news.
Well, news and world events are always broadcast in major TV news services. This way, you can first follow news in your native language to get a general understanding of what is happening around the world. This general knowledge of current events will help you understand more when watching the news in your foreign target language and your anxiety level will decrease significantly.
