Unlike frogs that metamorphose from tadpoles into adults within a one-year period, it takes three to four years for the mountain yellow-legged frog of the Sierra Nevada to reach adulthood, and so they are restricted to deeper bodies of water that do not dry up in summer or freeze solid in winter.
it takes three to four years for the mountain yellow-legged frog of the Sierra Nevada to reach adulthood, and so they are
it takes the mountain yellow-legged frog of the Sierra Nevada three to four years until it reaches adulthood, and therefore it is
in the Sierra Nevada, mountain yellow-legged tree frogs take three to four years to reach adulthood, thus being
mountain yellow-legged frogs of the Sierra Nevada take three to four years until they reach adulthood, thus
mountain yellow-legged frogs of the Sierra Nevada take three to four years to reach adulthood, and so they are
D 的thus restricted可以做adulthood的后置定语，歧义
and so 看作为等于and therefore“，意思“因此，所以”其中，and为连词， so为副词；
但是so做副词有因此的意思吗？

有人提到so...that...但这里的that的作用应该是引导修饰water的从句，不是so...that...
我记得有一道题的解析是and so不OK
说是只有在so作“也”，即adv.时，才可以用and so的表达方式
但这里and so明显是顺承因果关系，不会是也的意思，有点困惑
选项C：
作为伴随状语being为多余。
and so 因此 可做连词
“The children behaved badly and so the teacher kept them after school. ”
前面可以不加逗号
C中，being表伴随；但青蛙需要3到4年成熟是个常态，是青蛙的属性，并不是在讲一个过程，不应该用伴随修饰。
you can also just remember this structure as an idiom: "take [TIME PERIOD] to + verb"
The mechanic took only 20 minutes to perform a complete tune-up on my car.
there's no other construction that is idiomatically acceptable with "take + (time period)", so, if you're good at memorizing things, this one is black-and-white.
这两个动作并不时同时发生,而是两个动作存在因为关系,前一个动作导致了后一个动作,应该用因果 关系的并列句来表达该逻辑关系
mountain yellow-legged frogs of the Sierra Nevada take three to four years until they reach adulthood, thus
and so 连用是什么意思……
2个分句是相对独立的，后者不是前者的结果。所以用and连接，选E不选D。
请问E选项中and so they are是什么结构？so在这里起什么作用
so...that
不是so...that...，that是water定语
是我没理解，我是错的。纯粹是表达一个原因。谢谢！
and so 因此

请问take 的主语可以是人吗？不是一般都是 it takes sb. sometime to do sth. 吗？
