If aliens are discovered one day, scientists fear their language may make it impossible to understand them. But John Elliott has come up with a program. The program can figure out the structure of the aliens' language. He thinks that's the first step in understanding what they say. Dr Elliott's program would compare an alien language to a database(数据库) of 60 different languages in the world to look for a similar structure. He believes that even an alien language will have its own structure. “Language has to be structured in a certain way, or it will be hard to use,” he told a magazine. Research has shown that it is possible to know if a signal carries a language rather than a picture or a piece of music. Dr Elliott has gone further by finding a way to pick out what might be words and sentences. Because languages have different word orders, Dr Elliott has set up a library of the sentence structures of 60 human languages. If a message is received from outer space, it could be compared against this database. Scientists would then be able to see if it's similar to any human language, or a mix of the languages. However, Dr Elliott also said that in order to translate what the aliens actually say, it may still be necessary to have a code(密码) book. ( )1. Why did Dr Elliott come up with the program? A.
