题目分析：
小题1:句意：Lucy 的钢笔比Kate的更好。同义句只是将比较的事物进行了调换，也就是说Kate的钢笔比Lucy的更差一些，good 反义词是bad；better反义词是worse。故填：worse than.
小题2:句意：Betty必须一天吃三次药。Three times a day(一天三次)是频率，对其提问用how often; 对次数提问用：how many times. 后面中does已经体现出单数，因此has 要用have. 故填：How often have to .
小题3:句意：我母亲骑自行车去上班。By bike 是交通的方式，对其提问how.疑问词后接一般疑问句的形式，原句goes 体现是单数，因此前用does ，将goes改为原形go.故填：How does go.
【小题4句意：这对双胞胎经常在周末拜访他们的叔叔。Often与On weekends,体现一般现在时，而转换的时间为next weekend展示的是下周，故时间变为一般将来时，计划或打算用be going to do 形式。故填：are going to visit.
小题5:句意：当他五岁的时候，他开始学习英语。when he was five years old.当他五岁的时候，与at the age of +基数词表示年龄是同义。故填：at the age of five。
