　　有很多的问题,duringtheiredrill和inthefiredrill一样吗?

　　是howdidtheearlymenmakeafire还是howdidtheearlymentomakeafire?

　　是whatmayhappenifwedon'tcarefulwithfire还是whatmayhappenifwearen'tcarefulwithfire?switchoff和closeto意思一样吗,不同在哪里?thethievesfoundithardtostealthebag是啥意思?我要以为我笨,我只是掉进了我给自己设的怪圈里了.希望高人指教,要正确答案,最好有讲解,（因为是新人,没钱.）
