基于在現(xiàn)在依舊艱險(xiǎn)的經(jīng)濟(jì)狀況下市場(chǎng)已恢復(fù)的程度和達(dá)到那個(gè)指標(biāo)的難度,這是一個(gè)不尋常的（估測(cè)）數(shù)據(jù).
Given在這里就跟provided有點(diǎn)像,翻譯成“基于”就可以了,其實(shí)就是表示“在（后面這一系列的狀況）下,這個(gè)數(shù)據(jù)很不尋常（that is an extraodinarily figure ）”
我的經(jīng)驗(yàn)是,遇到這種句子,可能改變一下順序比較好翻譯：
Given how far the market has already come and how hard it will be for it to rise to that number in what is still a harsh economic environment,that is an extraodinarily figure.
這樣看起來(lái)翻譯中文的時(shí)候方便一點(diǎn).
