Thereareabout1．5billionEnglish language learners
worldwide currently，says British Council member John Knagg．The group is one of the largest providers of English language instruction in the world．It has more than 3，000 full time English teachers globally．
English language learners worldwide are largely divided into two groups: The British Council says that there are about 750 million English as a foreign language(EFL) speakers and about 375 million English as a second language(ESL) learners．The distinction is that EFL speakers generally are those using English sometimes for business or pleasure，while ESL students use English on a daily basis．
SomethinkthatESLstudentsonlyneed to know the
language to connect with native(本土的) speakers，because English is required for those living and working in English speaking countries，which is a common misunderstanding．English is also generally used between nations where English is not the primary language．These countries use English as a common language to make it more convenient to do business and cultural activities．ESL students in any country will certainly have more opportunities to use the language．
The number of English learners around the world is also expected to increase．It is said that more than 2 billion people will be using the language in the near future．Countries from India to Somalia are calling on teachers，particularly native speakers，to travel abroad and share their knowledge of English．John Knagg said，“The shortage of ESL and EFL teachers has continued in recent years，and it presents one of the largest challenges to education across the globe．”
The European Union recognizes 24 official languages within its member states as well as a number of other minority(少数民族) languages．Because of the different languages and cultures in the EU，there has been a push to accept one common language for dealing with foreign business．Still，workplaces within its member states use the 24 accepted primary languages，especially English．Learning English has become the pursuit(追求) of keeping updated on rapid globalization，but fortunately for the EU，many people in its member states speak English quite fluently．
