Answer 1

since sth won the bid .....改为since winning the bid to..... 为什么 won变winning?
(因为since在这里被当成介词用了，介词+动词-ing 形式)

festivals are meant to celebrate important times of year. 这里time为什么加s ？
9因为节日不止一个，所以一年中重要的时刻也不止一个，要加s。）

he rose to his feet in one swift movement at the sight of the police 这里的 rose to his feet 怎么理解呀
（rose to his feet ：抬起（或端起）他的脚）

not many stories are found written in that particular style 这里的not many stories 怎么理解
（not many stories：不是很多/ 不是所有的故事/ 没有多少故事）

mother wanted to be a good provider,a role she has been shouldering since her marriage to
father. 这句的a role ....后为什么这样写？
（这个我也不理解 =.=**）

Bill was doing a lot of physical exercise to build up his_____
a.force b.strength c.mind d.ability 这里在咋选b 其他怎么不行？
（因为做运动是为了强身健体，所以选B是比较符合题意的。。）
（就是类似做运动是为了增加力量的意思。。）

Answer 2

我来分别改正和补充一个：
rise to ones feet 站起来；
a role she has...整句是个同位语从句，是对a provider 内容的补充。另外，a role后面是个宾语从句。
