Dialogue 6

A: Hi, I watched a TV program last night. It's that water will become less and less in the future.

B: Really? That is so terrible because we need water for our daily life! 

A: Yeah, the TV program also said that scientists will find other ways to wash our clothes. 

B: Like some gas which can get the stains off our clothes? 

A: Hum, that's may be a good solution. The program also mentioned that maybe in the future we won't need water when we get thirsty, we will take some special food.
