[连句成文]

Life in 2025

What will our life in 2025 be like？No one knows for sure，but it's certain that it will change a lot.In my opinion，in our life，mobile phones and computers will be more and more popular，but they will be powered by solar or wind energy because more energy should be saved.Besides，we will wear clothes made of special materials，which can change into the colour and temperature we like.

In 2025，I think some super－speed bikes will appear and cars using solar energy will be more popular.People will be likely to be living underground or on other planets.

In conclusion，life in 2025 will not be quite like what it is now.
