survive ,及物或不及物，survive from/on/as sth，survive sth，在……中幸存下来，如：survive the crisis; survive the winter; survive the long trip。
has survived a close brush with extinction，从与灭绝的冲突中幸存下来。所以主句是讲G差点灭绝，后面讲它现在的数量是以前DDT时期的5倍。这个语意有转折，不能用缺乏转折连词的伴随状语/独立主格；A，并列句，ok
未划线部分是单数，they 不正确，排除CD

E：“now with numbers five times greater than” does NOT modify the idea of "surviving a close brush with extinction"; instead, it is a much later situation, far removed from (and in considerable contrast to) the near-extinction. Therefore, a modifier is inappropriate here; a separate clause, written in a different tense (as in the correct answer), is a better solution.
未划线部分是单数，they 不正确，排除CD
now with错：第一，修饰主语gyrfalcon，表示伴随survive的动作，不合逻辑 排除E
"
2.原句用分号，两个句子，时态不同，前句现在完成时:讲的是鸟从extinction中survive了，后句一般现在时now：补充说明 不仅活下来了，还变成了5倍
D,E 改成with伴随状语，没有写成分号两个句子好。
3.now with错：第一，修饰主语gyrfalcon，表示伴随survive的动作，不合逻辑
第二，前句有with extinction，这里再用with，容易让人产生两者平行的歧义
重点：
1.numbers用greater不用more
2.主语单数用 its 不是they their
cd中they无指代
e如果用with会发现，这句话没说完，后面还缺了一部分，不可以做伴随状语
伴随状语概念：在句中，句首，句末的分词短语，从句主语等于主句主语
D E 状从修饰错误
不可以，with可以引导独立主格，with还有很多种正确的用法，在英语里是非常常用的。E错在不应该用独立主格，就算没有with它也是错的，同时没有说是谁的numbers。登录 或 注册 后可以参加讨论
