C
something need to be done= need doing被动
need to do 需要做 主动
C
C need+doing，用ing形式表示被动，是固定用法；后者当做使役动词来使用，两个使役动词中间需要动词不定式来隔开
答案为C.
need在此句中意思是“需要”，need doing/ to be done。例如：
The flowers need watering/to be watered.
第二空考查need做实义动词，need to do, 其否定式为：don't need to do。
选 C
第一句 主语是the meachine 需要修 sth needs doing/sth needs to be done
第二句 need to do sth 需要去做 /do not need to do 不需要去做
