【正确答案】To have a good command of one foreign language is rather complex, since it involves a conflict between the divergent motives in language learning and the suitable approaches dealing with the target language. However, the final judgment should depend on a case-by-case analysis of several key factors.
To begin with, since the 1980s, China has witnessed some dramatic changes in its relationship with other countries. As a result, more foreign companies have already invested in China. Under such situation, it is not surprising at all that a growing number of people, young ones in particular, are particularly interested in foreign language learning, for their linguistic competence will probably be a passport to an esteemed joint venture or bring to them a vacancy with the handsome salary. Additionally, some observers believe that sufficient financial support from the renowned educational institutions abroad also contribute to the increasing number of language learners. For example, in China, if a student performs well in such tests as TOEFL or GRE, he is more likely to be admitted by a foreign university. This consideration can also partly account for the increase of language learners. However, in some other instances, the above-mentioned situation is not always adequate. For instance, it is quite possible that a man learns a language out of his interest, or he is planning to work as an interpreter. Surely enough, these are exceptional cases, yet they do exist.
Given the analysis above, it is justified to conclude that it is a social phenomenon nowadays that more people begin to learn a foreign language. As Samuel Johnson put it, "Words can't move mountains. It is diligence that accounts. /
