不努力就不会成功__________________________ 答案：【答案】You will never succeed without efforts. 【解析】根据中文，succeed成功，是动词，作谓语；effort努力，是名词，此处用复数efforts；“不努力”可以用without引导的介词短语充当条件状语，故答案为You will never succeed without efforts.11．解方程（组）（1）$\frac{x+2}{3}$-$\frac{x-1}{2}$=x+1（2）$\left\{\begin{array}{l}{2x-y=5}\\{x-1=\frac{1}{2}（2y-1）}\end{array}\right.$．
