小题1:aren’t used
小题2:How should
小题3:so, that
小题4:have/get, cut
题目分析：
小题1:把含有be动词的肯定句变为否定句直接在be动词后面加否定词not即可，因为所给的是两个空，需要are not使用aren’t；故答案为aren’t used
小题2:划线部分为介词短语做方式状语，所以用特殊疑问词how来提问，故答案为How should
小题3:too +形容词+ to do意为“太……了以至于不能”，相当于so…that…意为“如此……以至于”，故答案为 so, that
小题4:have/get sth done意为“使……被做”，故答案为have/get, cut
