As free as they make us，mobile phones still need to stay close to a power source.Soon that may change with “green” power.

Three Chilean students got the idea for a plant­powered device(装置) to charge their cellphones，while sitting in their school’s outdoor courtyard during a break from exams，with dead mobile phones.Then，one of them had an “aha” moment.

“It occurred to Camila to say about plants，” said inventor Evelyn Aravena.“‘Why don’t you have a socket，if there are so many plants？’ After that，we thought，‘why don’t they have a charging outlet？Because there are so many plants and living things that have the potential to produce energy，why not？’”

Their invention—a small biological ci rcuit called E­Kaia—uses the energy plants to produce during photosynthesis(光合作用).A plant uses only a small part of that energy and the rest goes into the soil，and that’s where the E­Kaia collects it.The device plugs into the ground and then into your phone.

“It’s the most amazing project I’ve ever seen in my life，plain and simple.They brought this original model，and it worked—and that’s when it all changed，at least from my personal point of view and I began to support them，” said Mauricio Cifuentes.

The device solved two problems for the engineering students—they needed an idea for a class project，and an outlet to plug in their phones.

“Looking for a place to charge the notebook，which had no power，and the mobile phones，we weren’t able to find anything becau se all the other students were in the same state of madness trying to find a place to charge their devices，” said Aravena.

But plants are everywhere，and the bio­circuit makes the best of their excess(过多的) power.

The E­Kaia doesn’t carry much charge but it’s powerful enough to completely recharge a mobile phone in less than two hours.

The student inventors have applied for patents on their technology，and expect the E­Kaia to go on sale in December 2016.

The best example of universally understood body language may be the smile.A smile can open doors and tear down walls among 5 .

I have organized and reorganized an 6 with the dentist for months.I also 7 it twice and called the day before to 8 all the paperwork would be ready for the x­rays.Then I arrived.It wasn’t 9 at all.The lady there even had no 10 what I was talking about.I 11 felt my blood boil.I was getting so 12 .I didn’t yell at her but I may as well have because the 13 I was talking to her was not nice.I spoke down to her as if she were a child and incapable.It was not a good moment.The whole time she smiled and was 14 to me.

Only when everything was finally 15 was I nice.I sat down in the waiting area and 16 it all.How can I make it better？How can I make up for my 17 behavior a moment ago？I couldn’t.I could 18 her a chocolate bar I had on me，but this needed more than that.It needed an honest 19 and that is exactly what I gave.

I apologized for the way I had spoken to her and told her it was wrong of me.She
