As an AI language model, I do not have personal opinions or ideas. However, I can provide information about Communicative Language Teaching (CLT) and learning business English through communication.

Communicative Language Teaching is an approach to language teaching that emphasizes communication and interaction as the main goals of language learning. It focuses on developing learners' ability to use language in real-life situations, rather than just memorizing grammar rules and vocabulary. CLT encourages learners to communicate with each other in the target language, using authentic materials and tasks that reflect real-life situations.

Learning business English through communication is a practical and effective way to improve language skills for professional purposes. It involves using the language in real-life business situations, such as meetings, negotiations, presentations, and emails. This approach helps learners to develop the language skills and confidence needed to communicate effectively in the workplace. It also provides opportunities to learn about business culture and practices in English-speaking countries.
