20． spent playing
【详解】句意：昨天弹钢琴花了她半个小时的时间。spend...doing sth.“花费……做某事”符合语境。原句时态为一般过去时，所以谓语动词spend应用过去式。故填spent；playing。

32． differences between
【详解】句意：男人和女人不一样。
根据句意理解可知，这里表达的是“男人和女人有不同点”，所以这里缺的是“不同点”，英语是difference，是一个可数名词，而空格前be动词用的是are，所以这里要用复数形式，而表达“在……之间”用的是介词between，构成between … and结构，故答案为differences，between。
33． by bus
【详解】句意：他们乘公共汽车去体育中心。通过句子对比可知需要替换的词语是took a bus“乘公共汽车”，其同义词组为by bus；故答案填(1). by (2). bus。
