Introduction to English Grammar - Vocabulary, Pronunciation and Listening Many non-native English speakers find when they study the English language that there is quite a leap from basic informal conversational English to more formal business-like English. The use of colloquial expressions by native English speakers can also be quite confusing to the non-native speaker. In this free online course you will study comparisons between informal and formal uses of greetings, introductions, offers, expressions of gratitude and apologies. You will learn how to recognise the differences between these so that you will be able to decipher what exactly is being communicated. You will practise examples to further increase your knowledge and understanding of the English language. This free English Grammar course will be of great interest to all learners who want to go beyond a basic level of spoken and written English and take their knowledge and understanding to a higher level.
