Scientists and engineers ____1____ (prepare) for possible travel into interstellar space, the area in between stars, in the distant future. Experts believe it will likely take many years before the technology and equipment are developed ____2____ (send) humans to this unexplored area of space. But if it does happen, massive spaceships ____3____ carry humans on long trips to distant starts.
Two American researchers, Andrew McKenzie from the University of Kansas and Jeffrey Punske of Southern Illinois University, have explored one possible problem with such travel. They considered the possibility ____4____ changes in human language could develop over time, thus ____5____ (cause) major communication problems with people on Earth.
Languages naturally change as communities grow more isolated from each other, the researchers noted in the paper. The long isolation of a community could lead to enough differences in language to make ____6____ impossible for community members back home to understand. The researchers noted that in____7____ (add) to new words being used, the language of people traveling on spaceships and living in colonies ____8____ (experience) many other changes. For example, the sounds of different letters would likely change over time, affecting not only individual words, but the whole grammatioal system.
The researchers say one possible solution to ____9____ (limit) communication problems would be to include language experts on spaceship crews. Another suggestion is to use sign language as a form of communication. McKenzie added that space travelers might question whether it is even worth trying to learn how to communicate with people on Earth. But he believe there will always be a need, even _____10_____ it is very limited. “You have to learn a little Earth English to send messages back, or to read the instruction manuals and information that came with the ship,” he said.
