请问有谁帮我解答一下以下英语的单句改错题，要求有二：1.指出错误选项并改正 2.写出错误原因，谢谢！

首先要说明，我不太清楚，这个ABCD是怎么划分的，不知道是指他前面的一个词，一段话还是他后面的什么。所以姑且凭语感来了。作参考吧
1,Like most people ,I was brought up to look upon (A)life as a process of getting .It was not until(B) in my late thirties did I make (C)this important discovery: giving away makes life so much more(D) exciting.
解答：in my late thirties did I make (C) 改成 when I was in my late thirties
我也不是很有把握，但是感觉这样比较通顺。

2. Planes are the fastest (A) way to transport (B) food. They are especially useful carrying food to people and animals that can not(C) be reached (D) otherwise
解答：Planes are the fastest (A) 改成 air transportation is the fastest 原句的话，感觉逻辑有问题。什么叫planes are way？意思上不通顺，单复数也不一致。
3. He got up, walked across the room, and with (A) a(B)(sharp quick movement flung (C)the door widely (D)open
解答：widely (D) 是wide open 只有wide open，表示门大开

4. At (A) a mini mum, the negotiators are hoping to achieve (B) an agreement an agreement in principle (C), with details worked out (D) later
解答：worked out (D)working out 用的是with 而且是非谓语，表示从属并且同时发生的事情，应该用ing式
5. In note-taking (A), a strict discipline has to be kept (B) and all inessential details ignored (C) and unnecessary words eliminated (D)
解答：a strict discipline has to be kept (B) 改成 strict disciplines have to be kept 我的理解是，这句话是省略。In note-taking, strict disciplines have to be kept and all inessential details （have to be） ignored and unnecessary words （have to be）eliminated
因为前面have to be都出现过了，所以省了。因为后面两段都是复数形式，所以，只能改B这段了
好大工作量啊~~~
