Step-by-step explanation:
Maybe you have heard the story about a foreign student coming to the UK to study law. At passport control, an airport employee asks him about the purpose of his visit. The student answers: "To study love." That's how he thought "law" is pronounced in English. :) This story is a perfect example of why pronunciation practice is so important when learning a language.

Such misunderstandings can happen when people learn a foreign language the wrong way. The student's folly is a very common mistake for new language learners – trying to pronounce words the way you spell them. As far as I know, there are no languages where all words are pronounced exactly as they are spelled. So, how can you avoid this mistake when learning to speak a different language?
