1、Tom‘s mother made him 【play】 the piano for two hours yesterday（应该是make doing让某人一直做某事，强调动作的持续性是，后面不是for+一段时间吗）
2、this company was the first 【to produce】portable radios aas well as cassette tape recorders in the world（为什么不是producing）
3、we haven’t decided which hotel to stay at（为什么不是stay）
4、How happy they were 【to see 】each other(为什么不是seeing，不是be doing吗)

make sb do 是固定短语,牢记哦.the first 之类的序数词必须加todo这个就好比 i don't know what to do next ……具体的应该是特殊疑问词＋不定式这个用法吧我认为是to do 不定式表示原因例如i am glad to see you希望对您有所帮助.
