答案

during the fire drill 表示在这个射击训练的期间,表示这个情况的一段时间
in the fire drill表示在这个射击训练的时间内.
是how did the early men make a fire,这样的特殊疑问句要是分不清,就把他们还原成陈述句,此句经还原应为The early men made a fire by ……而不是The early men to make a fire by ……
（因为此句语法不通）
是what may happen if we aren't careful with fire,因为有词组be careful with
switch off 1.关闭 2.（使）没兴趣 3.是停止谈话
close to 1.离……近 2.与……关系密切
