例文】This mountain is one of the biggest Alpine climbs in Europe. It has a very famous north face route – but it’s also notoriously dangerous. It was one of the last great parts of the Alps to be unlocked (first climbed in 1938). I have climbed it a couple of times – it’s wonderful in good conditions, but it has its own weather system and it can become very dangerous very quickly.
