[单项选择]Though it is becoming increasingly easy to move from place to place, our inability to communicate with one another gives rise to numerous misunderstandings and makes real contact between people of different nationalities impossible. Many attempts have been made to overcome this problem, but they have all failed. The fear of foreign influence and domination rules out the universal acceptance of any one of the existing major languages.
Linguists(语言学家) have succeeded in making their artificial languages extremely simple so that they would be easy to learn, but their efforts seemed doomed from the start. The reason for this is that there is no real incentive (动机) to learn an artificial language. There is nothing to guarantee that everybody is willing to make efforts; there is no assurance that the learner will have an adequate return for his toil. When people today undertake to learn a foreign language, they are not interested only in speaking it.
