請將下面這段話翻譯成英文：
1936年竺可楨授命出任浙江大學校長。在此之前，他已經(jīng)是一位聲名卓著的自然科學家了。從1936年到1949年，竺可楨當了十三年大學校長。在連綿不斷的戰(zhàn)爭、學運的夾縫中，在極為惡劣的環(huán)境下，他跋涉五千里、五易校址、歷經(jīng)五省、顛沛流離，居然將這所他接手時只有三個學院、十六個系的大學辦成了擁有七個學院、二十七個學系全國最完整的兩所大學之一。
參考答案:
In 1936,Zhu Kezhen was appointed as the principal of Zhejiang University.Even before then,he had been a famous natural scientist.From 1936 to 1949,Zhu Kezhen worked as the university principal for 13 years.In the extremely hostile environment filled with converging attacks by continuous wars and various university affairs,being homeless and miserable,he trudged 5,000 li and drifted from place to place through 5 provinces,with the university location being changed 5 times.He actually developed the university into one of the nation's two most integrated universities composed of 7 schools and 27 departments,compared with only 3 schools and 16 departments when he took it over.
他跋涉五千里、五易校址、歷經(jīng)五省、顛沛流離，
分析:
顛沛流離:drifted from place to place,這個詞還有另外一層意思就是“無家可歸，生活痛苦”，為了意思表達的全面，將“homeless and miserable”以分詞形式作伴隨狀語譯出，可以表達這是一種持續(xù)的狀態(tài)。
