(答案→)want后加to
解析：
【小题1】want to do sth. 为固定搭配。
【小题2】依据上下文，前句a chocolate cake为可数名词单数，后边的代词显然用it，而不是them。
【小题3】此行无错。
【小题4】不定代词other指另一个，而others指另一些。
【小题5】此题考查动词的时态。宾语从句主句用一般过去时，从句要用相应的过去时态。
【小题6】本句缺少谓语，需要把making改为make的一般过去时态。
【小题7】过去分词作定语，修饰something，故去掉what。
【小题8】one night前不需要任何介词。
【小题9】loudly是副词，此处修饰名词music，应用形容词。
【小题10】应用形容词与系动词一起构成系表结构。
