such an outcome,if it happens,could cause a political controversy;or it could lead to more power being transferred to the eu in the worst possible circumstances,namely when the union is deeply unpopular.

參考答案:

要點(diǎn)：這是一個(gè)復(fù)合句，條件從句很短，所以置于主謂之間，造成句子，翻譯時(shí)應(yīng)將從句提到句首。"namely when the union is deeply unpopular"是一個(gè)狀語從句，用來解釋"the worst possible circumstances"。

譯文：這種情況一旦發(fā)生，就可能引起政治上的爭吵；即使在最糟糕的情況下即在歐盟很不得人心的情況下，也可能使更多的權(quán)利轉(zhuǎn)移到自己手中。
