the car needs repairing是不是被动句

Question

1,The car needs ___,I'll use it this Wednesday.
这道题应该选repairing.require/need doing：需要被做（主动表示被动） 需要被做（主动表示被动）但是用to be repaired为什么不行呢?
2.It is five years since we began to enjoy a ___spring festival each year.
A.ten-day B.ten day C.ten day's D.ten-day's

Answer 1

1.根据语法分析,need to be done 也是可以的,但是相对于need doing的主动表被动来说,后者更好一些.如果这两个答案出现在在一个题中,就选need doing,如果不是应选need to be done.
2.A ten-year 相当于一个名词.这个类似于 A five-year-old boy的句型
