my feeling about trip to singapore polytechnic

That day, it ws a early dismissal. I followed my class to Singapore Polytecnic for the learning journey about the using of solar energy. I learnt a lot on the ways of using solar energy. I also realised that the importantce of saving energy. I learnt about the alternative energy sources. The solar energy is also enviromentaly friendly. My second opinion was that the professor is very friendly and patient he answered all of my questions carefully and accurately. At the end of the learning journey, I feel very contented of the trip, it was really a fruitful journey.
