Another method by which people appear to apologize without actually doing so is to say "I'm sorry you're upset"; this suggests that you are somehow at fault for allowing yourself to get upset by what the other person has done. (06.1 Passage 2)
主干:Another method...is to say...; this suggests that...
本句是由分號間隔的兩個分句構成的并列句。前一分句中,by which引導定語從句,修飾主語another method,不定式to say作表語,引號里的直接引語作say的賓語。后一分句中,that引導的從句作suggests的賓語。
譯文:另外一種表面上看似乎是在道歉,而實際上并沒有道歉的做法是說“你感到委屈,我很抱歉”,這表明,如果因為別人所做的事情而讓你自己感到委屈的話,那么你多多少少是有過錯的。
