羅斯島上三個(gè)阿德雷企鵝種群---約130000對(duì)育種企鵝---的小企鵝的存活率可能有問(wèn)題.
Problem can have:是很少見(jiàn)的用法,所以也懷疑這個(gè)句子可能問(wèn)題,即應(yīng)在the chick survival rate at 后面有別的成分,如very low,即：
The problem could have the chick survival rate very low,at the three Adelie penguin colonies on Ross Island - estimated at 130,000 breeding pairs.
這樣就譯為：
這個(gè)問(wèn)題能令羅斯島上三個(gè)阿德雷企鵝種群---約130000對(duì)育種企鵝---的小企鵝的存活率很低.
