First, we will have made certain contact with lives  from other planets, 3. will change the way we look at the world and the universe. The most important outcome (结果) of this may be the uniting (联合) of the world.

The development of technology is a certainty. This can have many 4. (differ) outcomes, but it is clear that the new technology will have a major influence 5. human society.  Simply 6. (speak), the next 84 years will determine whether humans have a future here on this planet.

We are facing many challenges that are  forcing us 7. (choose) whether we will  change  the  way  we  live 8. die. We must use  our technology  to  bring  about  a  much 9. (good) world. If we are unable to solve our problems 10. (successful), it appears unlikely that we will have much of a future beyond the end of this century.
