完形填空。 These days, it is easier for us to travel to other countries than ever before. However, there is a big difficulty that most of us _1_ when we meet people in other countries--we cannot communicate with them. There are _2_ where English is still not spoken, though it is the most widely known language. So, wouldn't it be _ 3_ if there was one language that could be understood by anyone anywhere in the world? Esperanto that was created in 1887 may be the world's _ 4_ truly international language. In fact, although _ 5_ artificial (人造的) languages have been already created, only Esperanto has had much success. Its learner say that it is about four times _ 6_ to learn than other languages.

The grammar is also as simple as possible: only sixteen basic _ 9 _, no irregular verbs (不规则动词), only six verb endings.

Anyway, we hope that some day one language can be mastered easily by anyone. (     )  1. A. need (     )  2. A. offices (     )  3. A. safe (     )  4. A. first (     )  5. A. little (     )  6.
