discussion in the class

I discussed about car with my class mate in the speaking class today.

First, an opinion of one of the speaker's was 'Exhaust gas. from the cars has a bad influence to environment.' It is true, but in my opinion, most car companies invite new hybrid car. In mean time, the price of them is so expensive. But if many people buy them instead of their normal car in near future, the price of them decline and easier to get the hybrid car than now.

After we discussed, we were very tired because mentioning our opinions is really difficult and it was so hard for us to translate what we want to say Japanese into English. I realized importance of vocabulary of English again!! (124 words)
