【小题1】在①处填入一个适当的连词使句意完整、上下文通顺：

【小题2】将②处划线部分译成汉语：

【小题3】将③处划线部分译成英语：

【小题4】在④处填入一个适当的疑问句使句意完整、上下文通顺：

【小题5】文中⑤处划线部分的it指代：
But

(答案→)But 解析：短文大意：许多人在他们的生日做相同的事情：他们有很多蜡烛的大蛋糕，听他们的朋友和家人唱“祝你生日快乐”。一些专家说，没人知道是谁写的“生日快乐”。他们还说没有办法知道人们何时开始唱这首歌。但是他们相信人们很久以前就开始唱它啦。【小题1】根据上句They have a big cake with lots of candles , and listen to their friends and family sing“Happy Birthday to You”和下句would you like to pay money to sing that song?可知该填写连词But 。【小题2】她在她的电影中使用了这首《祝你生日快乐》歌。【小题3】这儿的必须是客观要求的，该用have to，为……支付pay for，所以该句子译为But she had to pay ﹩1500 for this/it。【小题4】根据后面句子But they believed people started to sing it long before the company began to own. it.可知此处该填写When。【小题5】很明显，it指代的就是歌曲《祝你生日快乐》，所以可回答The song “Happy Birthday to You”。
