On the Filminute website, you can find many movies that last only one minute. It’s great practice for using English sentences to describe what you see.
Another website to visit if you’re very busy is Listenaminute, with almost 500 audio tracks about many subjects that only last one minute! Sean Banville speaks in UK English, so the listening is excellent if you need to prepare for IELTS. There are audioscripts and many quizzes and games that go with each audio track, if you want to improve all 4 skills together.
