单选题 According to the text, the ivory-billed woodpecker ______.

A、 is extinct since the year of 1994
B、 was found by a group of 17 researchers through the internet
C、 is called "Grail Bird" because it is hallowed to the degree of holiness
D、 is so famous that it has become a symbol of the spoiled relationship between human beings and nature

【正确答案】 D

【答案解析】首先，这种稀有鸟类并没有灭绝，文章正是讲述有人重新发现了它。其次，它肯定不是通过互联网同时由17人找到的。再次，这种鸟被称为“圣杯鸟”是因为它过于稀少，就像传说中存在但谁都没见过的圣杯一样，而并不是因为它很神圣。因此这道题选择D，可以在第一段的最后一句找到线索。
