    Being the global language, English has been deemed important in both the academic world and the work place. University students in Taiwan, accordingly, are required to reach a certain level of proficiency in English~commonly the intermediate level at leastbefore they are allowed to graduate. The requirements, however, have been received with both warm welcome and heated objections.      Take a stand on the issue of foreign language requirements and write an essay to either support or refute the necessity of such requirements.
