had them decorated 这里面的用法，谁能解释一下吗

那根据图形背景原则，为什么B选项，明明discovered和named延续时间短，be in the middle of the belt of asteroids延续时间长，却反而是延续时间长的作主句呢？

请问：关于C的解析我有个问题：noun modifier修饰名词时不是就近原则吗？那这样的话Including引导的现在分词短语不就是修饰它最近的pioneer journalist 的吗？
为什么解析说它有可能修饰Nellie Bly呢

least support，这一题问的是没有影响的而不是有影响的

请问老师，BC之间，C用了限定性定语从句，我觉得这样意思更准确，就是那些xxx的鱼和后面的鱼进行对比，如果只是B这样的非限定性定语从句，反而遗漏的句子的核心意思。但为什么最后答案是B呢？C有什么错误超越了定语从句的差别？谢谢！

A provision.. provide REDUNDANT

Generally, in + VERBing serves to modify the VERB IN THE FOLLOWING CLAUSE.
D: In having nests, situated underground or in pieces of wood, raider ants make a portable nest.
Here, in having seems to modify make -- the action performed by raider ants.

not one和no one的用法差别在哪呢？not one of 也用单数谓语动词吗？

A选项里，a merger agreement is signed that..., that修饰a merger agreement，但是that并不是紧跟着merger agreement, 中间有个‘is signed'. 请问这个算是跳跃修饰吗？

C
1) there's no such construction as "A, B, but C". i.e., "but" can't link three things in the way that "and" or "or" could.

2) it makes no sense to put all 3 of these things in parallel, because they don't belong in parallel; the last two are an explanation of the first one. i.e., the last two things are an explanation of the idea that these shoppers "do very little impulse shopping".

误选C，本题的意思是培训他们去做。。。要用to do

AE中选咯 主动大于被动 简洁为主

这个 B 的解释到底什么意思。呃~

厉害厉害！

这也就是有些动词和名词不能互换用，XX做YY可以，XX是YY就不对了。要注意注意，保持头脑清醒。

这里by...一定要紧贴着employed吗？先后顺序有关系吗？
比如A. by manufacturers and utility companies as product demonstrators and publicists,
改为A‘. as product demonstrators and publicists by manufacturers and utility companies,

提醒自己，不能看到直角三角形斜边长是5，就自动认为另外两边是3和4.

Over several hours, gravity will reassemble all but the fastest pieces into a rubble pile. 每小时换一次速度，就聚集不了了。

还有help （to） do又怎么解释呢，难道help约束力很强吗？难道一件事，我不帮你，你就不做了吗？
