Watching videos on YouTube can be fun because some videos are hilarious and others are insightful. At the same time, you will be training your ears by listening to people communicate in English. This too is a part of the learning process. After the video, there are usually numerous comments that are left by those who have watched them, which you can then go through to pick out parts and new words. It is easier learning this way since you get to know the exact context within which the word is used.
