答案

A
for the first time 相当于when用来引导时间状语从句.译为：当第一次...的时候.by the time常用于完成时.the first time做定语不引导从句.at a time when 的意思是:每当.时候
B
every +序数词+单数可数名词 译为：每第...
every + other +单数可数名词 译为：每隔...
every + few + 复数名词 译为：每隔几...
every +基数词+ 复数名词 译为：每...天
D
whatever 引导宾语从句.做 I would do whateverI can (do)第二个do的宾语.
to save 是不定式表示目的,做目的状语
