　　1、While it cannot be denied that there is no guarantee that affirmative action will achieve these results,

　　neither can it be denied that there are plausible,even powerful,sociological and economic arguments pointing to its likely success.

　　參考答案：

　　【妙譯】雖然我們不可否認要使這種方案達到效果并無保障，也不可否認其有著可能成功的、令人信服的，甚至強有力的社會學、經(jīng)濟學方面的論據(jù)。

　　【點撥】a.本句為一個復合句，主句為“neither can it be denied”，it為形式主語。其真正的主語為主語從句“that there are plausible…..likely success”。由于否定詞neither放于句首，主句用了倒裝。>b.while引導的讓步狀語從句中，第一個that從句為主語從句，作讓步狀語從句中的真正主語，it是形式主語;第二個that從句是guarantee的同位語從句。
