but we have at least drawn near the point of admitting that birds should continue survival as a matter of intrinsic right, regardless of the presence or absence of economic advantage to us。
正确答案：
butwehaveatleastdrawnnearthepointofadmittingthatbirdsshouldcontinuesurvivalasamatterof
intrinsicrightregardlessofthepresenceorabsenceofeconomicadvantagetous
解析：句子主干wehavedrawnnearthepoint介词短语ofadmittingthat作定语修饰point其中嵌套了that从句作admit的宾语从句regardlessof作让步状语amatterof的问题大约;drawnear接近靠近;intrinsicright天生的权利固有的权利;economicadvantage经济利益经济优势
参考译文：但是我们至少已经几乎承认了这样一种观点：不管鸟类对我们是否有经济利益生存都是它们的固有权利
