復雜的否定句的拆分和理解 例186

例186　One can't be too careful in making the decision to explore the Mars as it was such a critical case and risked being failed without sufficient researches and experiments.

【結(jié)構分析】這句話是典型can not...too...，表示再怎么也不過分，是典型的否定表達肯定的用法，這句話的主干是One can't be too careful in making the decision to explore the Mars，后面是原因狀語從句as it was such a critical case and risked being failed without sufficient researches and experiments，其中有兩個動詞并列，分別是was和risked。

【亮點回放】此句話的亮點在于雙重否定句套上表示原因的狀語從句，很經(jīng)典，表示原因的狀語從句是用as引導，往往表達常識性的原因。

【核心詞匯】

careful　仔細

explore the Mars　探測火星

a critical case　一個關鍵的決定

risk being failed　冒著失敗的風險

sufficient researches and experiments　充分地調(diào)查和實驗

【參考譯文】一個人要特別小心去下探測火星的決定，因為這是個很關鍵的決定而且如果沒有充分的調(diào)查和實驗，可能冒著失敗的風險。
