答：A
译：在水中呆了整整一个晚上,然后她才游向岸边.
析：这是新概念英语第二册第33课后中国人根据原句Then she swam to the shore after spending the whole night in the water. 编的选择题.其实并不是什么好题目,是主编让他的一些学生编的,有些题目是有问题的.
这里的having done sth.=after sb. (had) done sth.
现在分词的完成式having done sth.表示这个动作先于主句的动作完成.
这样改写其实并不好.如改为：
Having spent the whole night in the water, .要更好些.

这句话是要表达在她游向岸边的时候已经在水里呆了整个晚上了，所以要用完成时态，而have spent 对于she 而言是主动的所以用ing形式

鄙人做SAT题中语法部分出现一些问题，求英语牛人相助啊！！！悬赏分：50 这道题题意不是很明白，帮忙分析下。麻烦了。答：those to= the

这个一个现在分词做伴随状语的句子，此句使用的是现在分词的完成式，表示在她游向岸边前也呆在水里，用swimming也可以，表示整夜她在努力游向岸边。

你好
答案是A
she swam to the shore having spent the night in the water.
==AFTER she had spent the night in the water.(先发生)，she swam to the shore（后发生）。
