找出从句,从哪到哪,并划分带从句的那整句话的句子成分,
If we see someone breaking the rules of etiquette,we may give them some suggestions politely.Perhaps one of the most polite ways is to ask someone,Wouldyou mind doing this or Would you mind not doing that.For example,if someone cuts in front of you in line,you could ask them,Sorry,would you mind joiningthe line?If someone is smoking on the bus,we could ask,Excuse me,could you please put out thatcigarette?People don’t usually like to be criticized,so we have to be careful how we do this.
