Although not so world-widely accepted,people who are emotionally weak in daily business are often losers who are not able to fulfill any fruitful achievements in their lifetime that they endure.
Although not so world-widely accepted,people (people是主语,句首的独立名词结构)who are (这个are在从句中,不是谓语)emotionally weak in daily business are (这个are是不能排除的,是谓语)often losers(losers 在谓语后的独立名词结构,是宾语) who are(这个are不是谓语,在从句中) not able to fulfill(不定式结构排除) any fruitful achievements in their lifetime that they endure.(endure在从句中,不是谓语)
所以,这句话的主干提炼出来就是:people are loses, 人是失败者。它的顺序和中文一致。
