答案詳解：
　　1.nor did they make any explanation / nor did they give the reason for doing so
　　本題考察了兩個知識點。① nor的倒裝句用法，后半句表示“也不”的否定意義，注意助動詞的時態與上半句保持一致；② 對某事做出解釋的表達，考察了漢譯英中動詞轉名詞的技巧，explain → explanation，或者nor did they give the reason for doing so同樣可以。
　　2.could be assigned (to) another job
　　本題考察了wish從句的虛擬語氣用法（can→could）和“分配某人做某事”的詞組搭配，assign sb. to sth. 或者assign sb. sth.
　　3.at the risk of his own life
　　本題考察了“冒著…的危險/風險做某事”的詞組搭配，可以用at the risk / expense of one’s own life（冒著某人的生命危險做某事）
　　4.①was his assistant who answered / picked up the phone；②turned out that his assistant answered / picked up the phone
　　該句比較靈活，在句法上，既可以使用強調句結構，也可以采用turn out的慣用搭配；在“接電話”的表達上，可以用pick up / answer the phone。強調句結構為it be sb. who do sth. ,而turn out變化則較多，可以用turn out to be sb. who do sth.或者turn out + that + 從句。
　　5. his father persuaded him into / talked him into
　　本題考察“說服某人做某事”的表達，persuade / talk sb. into doing sth.
