解答雅思口语中的两大偏僻TOPIC

　　Pls just take this as a reference:

　　SCIENCE LESSON/COURSE YOU HAVE LEARNED

　　据留学360介绍，The science lesson impresses me the most is the one about Darwin‘s evolutionary theory in my biology class. It claims all species on earth have actually evolved over millions of years through the process of natural selection. It’s really fascinating to me. And you know, the question about where we, human beings, came has always haunted me since I was a little boy. And this explanation did satisfied me for the time being, although I learned from elsewhere later that this theory was still not proved totally in itself. For example, the missing of fossiles evidences of some link species. I think I will follow this discussion through to see if it‘s, as suggested, the real science.

　　A PICNIC OR OUTDOOR MEAL

　　The picnic I can easily recall is the one with my workmates in Padstow Park.

　　It’s a warm spring day. We, nine people from 3 families, drove to the park in our neighbourhood, attractive for its green grass and crystal-clear stream. We not only shared some delicious home-made food with each other, but had lots of fun there. The kids of my friends, in particular, had a really great time together. They ran all around, playing games, fighting in the water. It was beatiful to just watch them laughting their hearts out. It seemed to carry all the burdons and worries away from me as well. It‘s always great to have a break from the busy workdays, isn’t it?

　　P.S: Just want to give you some general ideas and you may be able to add something of your own kind to it and make them more detailed and believable. Hope they are easy for you to follow and develope further. Good luck.
