If you're talking about me behind my back that just means my life is obviously more interesting than yours(yours是不是漏掉了?）
If 引導(dǎo)條件從句 If you're talking about me behind my back如果你們是在我背后討論我的話,
that just means my life is obviously more interesting than yours 另一個句子了,應(yīng)該用逗號和前面的條件從句隔開. that就是指代前面的條件從句,在這個句子里做主語,means是賓語
my life is obviously more interesting than yours 是賓語從句.

整句翻譯就是：那意味著我的生活很明顯是比你的有趣多了.
