ingenuity,a sense of humor,and imagination are needed to adapt activities to individual needs,and good physical coordination is necessary to demonstrate or participate in recreational activities.4624
问 1—sense of humor,and imagination are needed to adapt activities to individual needs。幽默感和想象力被需要去适应个人需要的活动。我把are needed to do 当成一个结构翻译成：被需要做某事。
2—good physical coordination is necessary to demonstrate or participate in recreational activities.这里的be necessary to do sth 是个句型吧：表示必需做某事？

答案

1—sense of humor,and imagination are needed to adapt activities to individual needs.
翻译成“默感和想象力被需要去适应个人需要的活动”像是老外说汉语,应该变通为“（人们）需要幽默感和想象力以适应个人需求的各种活动”.
2—good physical coordination is necessary to demonstrate or participate in recreational activities.
划分语法层次后就可以一目了然：
主语：good physical coordination
系表部分：is necessary
目的状语：to demonstrate or participate in recreational activities.
因此,这里不能孤立地看成是 be necessary to do sth 是个句型,意思是“为了示范或参加娱乐活动,好的身体协调能力是必要的”.
