GRE,GMAT,SAT經典長難句(07/50)

Unfortunately, the documentation of these and other epidemics is slight and frequently unreliable, and it is necessary to supplement what little we do know with evidence from recent epidemics among Native Americans.

資料來源：GRE考古題

解析重點：

第一：Unfortunately，句間轉折用詞，反正表示悲觀的態度副詞，兩句間的句兼關係會邏輯相反

第二：it is necessary to supplement what little we do know with evidence from recent epidemics among Native Americans

看到it開頭就要想到是不是傀儡了，會不會有主詞倒裝的情形，所以看到後面沒錯主詞就在to supplement what little we do know with evidence from recent epidemics among Native Americans這一大串，這是不定詞片語帶出事件當作名詞片語被視為本句話的主詞，一般都是把很長的東西方後面，這裡長短的定義不是看字數，而是看名詞後方有無子句的出現，以此為例to supplement＋what little we do know with evidence……，這裡不只有關係代名詞，還有介詞結構，所以只要後面還帶一堆拖油瓶我們都視為長名詞結構

第三：what little we do know

這個也是順序調換了，little這裡當副詞用，一般還原會是what we do know little，修飾動詞。這裡要跟前面的supplement做連結的話可以把what化成something that這樣又是一個關係代名詞，執得注意是supplement他是動詞，要小心看到ment不全都是名詞，supplement A with B就可以翻譯成補充Ａ的元素，用Ｂ的法法，中文化：以Ｂ的形式補充Ａ。

翻譯：這句話語序要稍微調整會比較好看

變成：Unfortunately, the documentation of these and other epidemics is slight and frequently unreliable, and to supplement what we do know little with evidence from recent epidemics among Native Americans is necessary.

不幸的事，這份有關於這些和那些流行病的文件太少了而且還經常性的不靠譜，還有從北美原住名身上的近代流行病得來的證據去補充我們對這文件的無知是必要的。

邏輯：

Unfortunately, the documentation of these and other epidemics is slight and frequentlyunreliable, and it is necessary to supplement what little we do know with evidence from recent epidemics among Native Americans.

反邏輯，文件太少，認知也少

單字：

documentation (n)文件，史料，這太簡單了，要講動詞才精彩，他有證實的含義

document (v) 證實= testify / verify / substantiate / confirm / attest / authenticate / corroborate

Epidemic (n) 流行病＝pandemic

Epidemic (adj) 流行的= prevalent / prevailing widespread / reigning

Epidemic (adj) 傳染性的= contagious / infectious / catching
