grammar(2)一問，有請高手解答～～４０點

應該如此斷句：classified as / vulnerable to extinction / on the internationally recognised Red List [說明：classified as: 被分類為。vulnerable to + N: (片語)易於受到某甚危害或攻擊，對某種危害沒有抵抗力。vulnerable to extinction: 瀕臨絕種（對絕種威脅沒有抵抗能力）。the internationally recognised Red List: 國際認可的紅色名單]

IUCN Red List 包含CR, EN, VU 三個等級內的物種。
此處 extinction = extinction risk.

Vulnerable to extinction 整個是N嗎？
是的。可以看成紅色名單中的一個等級（VU)，
也可以看成 a species vulnerable to extinction (瀕臨滅絕物種）
Species （單、複數同形）物種。

I think you mis-read it. "vulnerable to extinction" is one of the category on the IUCN redlist. I think it is the "VU" category as defined below.

Categories in IUCN conservation statuses
Summary of 2006 IUCN Red List categories.
Extinct (EX) - No individuals remaining.
Extinct in the Wild (EW) - Known only to survive in captivity, or as a naturalized population outside its historic range.
Critically Endangered (CR) - Extremely high risk of extinction in the wild.
Endangered (EN) - High risk of extinction in the wild.
Vulnerable (VU) - High risk of endangerment in the wild.
Near Threatened (NT) - Likely to become endangered in the near future.
Least Concern (LC) - Lowest risk. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.
Data Deficient (DD) - Not enough data to make an assessment of its risk of extinction.
Not Evaluated (NE) - Has not yet been evaluated against the criteria.
