还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
here are two examples to illustrate.
it is december 2007; the world record in the discus throw has stood since 1986.
it was july 1991; the world record in the long jump had stood since 1968. --> but it was broken later that year
c里面the 35 year表示现在就是release之后的第三十五年，意思不对，而且如果是这样，主句就要用现在完成时。而且，release是一个时点动词，应该用过去时
b,c 的since都是开放时间的标志，句子的谓语用的是过去完成时态，要求时间是封闭的，所以since的选项干掉
d, it的真正主语是后面的from the release,与原句句意不一致
e,it是形式主语，真正的主语应该是后面的their descendants had migrated,句意就变成他们的后代迁移到北至Texas的南方花了至少35年，这明显跟原句的句意不一致
时间状语独立存在的时候，不需要用介词引导。
* choice d: in this sentence, the commas + non-essential modifier ('..., when') seem to imply that the descendants' migration took place simultaneously with the release of the original honeybees. in addition, in this sentence, 'it' refers to some unspecified event (it can't refer to the descendants' migration, for the aforementioned reasons).
* choice c: 'the 35 years since' implies that the present is 35 years after the release date. not only does this conflict with the meaning of the original, but it also renders the past perfect (from the underlined part) inappropriate: you'd need present perfect in this case. also, since the release is a point event, it would belong in the simple past
* choice b implies that the honeybees' descendants somehow released them (perhaps a very bizarre case of karmic cycles, but absurd no matter what).

B releasing不对，C the 35 years怪怪的，DE都不对，所以选A
？
错选B，注意since后面的releasing的主语是their descendants了，排除
since只能表示现完，bc排除。d中when不对，排除。e中it took后面都没讲清楚，排除
B选项不对的另一个原因是，release是个有始有终的事件，所以要用名词形式，releasing是不对的
个人排除A的理由是：less than，什么less than 35 years吗？都没比较，起码得说 in less than 35years 嘛。
'less than 35 years after blah blah' is a TIME modifier, and, as such, must therefore be regarded as an ADVERBIAL modifier.
adverbial modifiers modify the entire action of a clause, not just a single noun. so, this modifier gives the time frame for the entire action described - which is of course exactly what we want to do.

感谢；原来如此

AB纠结；二选一又炸了；
A correct
B 不是descendant release African honeybees
D when 表示同时发生了

二刷错
二杀错。又选了c。 choice c: 'the 35 years since' implies that the present is 35 years after the release date. not only does this conflict with the meaning of the original, but it also renders the past perfect (from the underlined part) inappropriate: you'd need present perfect in this case. also, since the release is a point event, it would belong in the simple past.
(C) "had been released": passive voice, which could be OK, but we don’t really need it here. Generally, stick with active unless you need passive voice, or unless the other choices all have other errors.
The form of the word "release"
(A) "the release": This is OK, as it is a noun. "...35 years after noun (the event, in this case the release of bees)
(B) "releasing": The -ing form makes the entire phrase a modifier. It forces us to ask and answer the question "WHO released the bees?" The answer must follow the comma after the modifying phrase, but instead of a logical bee releaser (people), we find the bee’s descendents after the comma.
