It seems that the fame of outstanding figures is due to some stroke of luck. Throughout history， some famous people always have admired opportunities that lead to success. In daily life， some “l(fā)ucky dogs”（幸運(yùn)兒） never lack chances in their turning points. In fact， opportunities may come to everyone now and then.
    However， it is a pity that most people fail to seize opportunitiesg Why ⅡOpportunities “prefer” those who are prepared to grab. Without a ready mind， admired opportunities may slip through one's fingers.
    In my view， without diligence， willpower and continual efforts， opportunities are groundless talk. To be qualified for success， people should be equipped with necessary skills， rich experience and abundant knowledge besides numerous unusual qualities （素質(zhì)）。 In a word， opportunities are only catalyst （催化劑） of success， but not precondition （先決條件） of success.
    范文分析 除了多樣化的句子，多功能的結(jié)構(gòu)也可使表達(dá)錯(cuò)落有致。例如：第二段中的介詞短語(yǔ)“Without a ready mind”，可代替句子“If one does not have a ready mind”。分詞短語(yǔ)、不定式短語(yǔ)、介詞短語(yǔ)等短語(yǔ)代替句子，既能增加變化，又可加快行文節(jié)奏。當(dāng)句子內(nèi)容既可以用完整句，又可以用其它結(jié)構(gòu)表達(dá)時(shí)，不妨變換一下。（提示：變換要地道、自然、可信。不能單純?yōu)榱俗兓枚喾N多樣的語(yǔ)言形式。）
