2.How did it ____ that the ancient building was burnt down in an hour?
A.happen B.occur C.take place D.come about
答：D
译：那座古建筑在一个小时之内就烧垮了，怎么会发生这种事呢？
析：此题考与“发生”相关的四个动词和词组。本不应该出现在初三考试中，因为太难。
这题网上查到的是：江西省南昌市南昌一中、南昌十中2011届高三第三次联考英语试题_
中有第32题中。见到这题，我这个高中老师也拿不定主意到底选哪个好！答案D是参考来的。
为什么要用D. come about 而不用另外三个，还需要进一步查资料去证实，请稍等。
查网络上有关于这几个词用法的说明，摘录如下：
take place, happen, occur, come about和break out用法区别
这些词或短语都有“发生”的意思，但用法各不相同，区别如下：
(1). take place 表示“发生、举行、举办”，一般指非偶然性事件的“发生”，即这种事件的发生一定有某种原因或事先的安排，例如：
Great changes have taken place in our hometown during the past ten years.
The Olympic Games of 2008 will take place in Beijing.
(2) .happen作“发生、碰巧”解，一般用于偶然或突发性事件，例如：
What happened to you? (一般不说：What did you happen?)
Maybe something unexpected happened.
I happened to see him on my way home.
= It happened that I saw him on my way home.
(3). occur作“发生、想到、突然想起”解，其意义相当于happen，例如：
What has occurred? (=What has happened?)
A big earthquake occurred (=happened) in the south of China last month.
It occurred to me that she didn’t know I had moved into the new house.
(4). come about表示“发生、产生”，多指事情已经发生了，但还不知道为什么，常用于疑问句和否定句，例如：
When Mother woke up, she didn’t know what had come about.
I’ll never understand how it came about that you were late three times a week.
Do you know how the air accident came about?
(5). break out意思为“发生、爆发”，常指战争、灾难、疾病或者争吵等事件的发生，也可以表示突然大声叫喊等，例如：
Two world wars broke out last century.
A fire broke out in the hospital in the mid-night.
After the flood, diseases broke out here and there.
She broke out, “That is too unfair!”
从第4条解释来看，come about 表示“发生、产生”，多指事情已经发生了，但还不知道为什么，常用于疑问句和否定句，
用在这里似乎确实是最佳．
评；这属于＂推敲＂题了．会有争议，不该出．高考不太会出现，多出现在模拟考试中．初中更是不该出这样偏难的题．
PS；比如，我可以利用google证明，其它其中说法也是＂正确＂的，也是有人说的：
一．How did it happen that ... 找到约 673,000 条结果:
1. How did it happen that their lips came together?
2.　How did it happen that Catholicism is the only religion with a major central "power"?
3. How did it happen that Jefferson became Adam's vice-president?
二. How did it occur that... 找到约 11,700 条结果:
1. How did it occur that spirits promised to Allah (SWT) in pre-eternity?
2. How did it occur that Kris Allen got more votes than Adam Lamberg?
3. How did it occur that all these negroes are now "mentoring" these White children?
三. How did it take place that ...找到约 573,000 条结果:
1. But how did it take place that the acronym became well-known through the dot-com world?
2. So how did it take place that you are now functioning 7 days a week?
3. How did it take place that you got brought in here to this particular group, Wallace?
四. How did it come about that... 找到约 63,700 条结果
1. How did it come about that he knew it? 他是怎么知道那件事情的呢？ ...
2. How Did It Come About That You Joined The Corps?
3. How did it come about that the park was built? ...
如光成以上数据来看,take place为最佳了!
所以说,这种题的确没有意义. 就是让英美作家来选择,恐怕答案也是五花八门!

你这个有点高一的意味了，考点基本属于高一的，中考不会考这种的
1.D.在此之前我不知道，即过去不知道，你现在跟我说了，我现在就知道了，但在过去我不知道（有点绕，反正就是过去的事）
2.A这个没什么好说的，BCD没有后面加that的用法
3.B.with sth doing sth独立主格结构，高中里的知识点。
4.B这题就是死死地按词语的意思来。只有B恰当，是份额的...
