Hello, everyone. Today I will introduce you the learning chains in Britain. Here the chains refer to schools linked together as part of a group. They can offer students many practical advantages.
When people are asked to name a language school, more often than not, they think of one of the large international chains of schools. Some are vast language teaching organizations with schools in many different countries and may teach just one language.
One of the main strengths of these chains is the fact that their name is familiar to people all over the world. This can be a big advantage in the confusing world of language learning. Most students are bewildered by the large choice of schools and courses on offer, both at home and abroad, and so many prefer to choose a school which has a familiar name and an established reputation. Chain schools know this, and part of their success is due to effective marketing and advertising, which helps to keep their name well-known.<

The measure of man’s real character is what he would do if he knew he would never be found out.
