Refrection of ACEⅡ class

 ACEⅡ class of Wednesday 4th period is so enjoyable and useful for me because we have a lot of chances to speak English.  I often make some big mistakes.  For examples,"Is your～ is …?"  Of course, I understand such grammar but unconsciously say "is" again!  I always feel regret for such mistakes.  From now on, I'll take care more. 
 From next class, we'll discuss crime and criminal investigation.  Because I have never discussed this problem in English, I think I don't know a lot of words related to the topic.  But I'm looking forward next class!
