小题1: How often 小题1:so that 小题1: is it 小题1: been 小题1:that walked
小题1:划线部分意为“每两天”，指的是频率，对频率提问用How often。故填How often。
小题1:in order to do sth.“为了做某事”，表示目的，so that...“以便于......”也表示目的。故填so that。
小题1:考查反意疑问句。nothing“什么也没有”，表示否定。故反意疑问句用肯定。不定代词作主语，谓语用单数。故填is it。
小题1:ago用于一般过去时；而since加含过去时的句子常与现在完成时连用。“玛丽已经在中国三年了。”故填been。
小题1:考查定语从句。指人时用who或that；当先行词有序数词或最高级修饰时，引导词只能用that。句中含有1st，即first，故用that， 主句用的是过去式，故用walked。故填that；walked。
