1、C（A\D首先排除，时态前后不一致。然后我觉得在这个句子中不需要用完成时态，因为没有必要。）
2、C（B项应该改成to work with）
3、B（a series of 后面接名词的时候动词应该用单数形式，我搜到过例句）
个人意见，仅供参考。
1 B 强调对现在的影响
2 C have sth to sth
3 A 因为是debates 排除B D be scheduled for是一个固定搭配
这是一个陈述事实的句子 所以用一般现在时
1.C 给钱也是过去的,从那时起,是过去的时间.
2.B have no tools to do the work with意思是“没有用来干活的工具”.=have no tools with which she can do the work
3.B 第二周末要举行一系列辩论.
不过,有人说a series of后跟复数名词时,还是单复数都行的.
A series of books have been written abouther.
人们已经写了一系列与她有关的书.
A series of debates between the lecturers is scheduled for next weekend.
演讲者之间的一系列辩论将安排在下周末进行.
有些人说：一系列还是用单数的.
