not only may agencies select for genetic traits,some fear parents may start to as well in what might be considered the most extreme application of genetic information-designing children.

參考答案:

要點:該句主干結(jié)構(gòu)是not only...but also,因為用了as well,but aslo省略了。這句話倒裝是因為not only放在句首。翻譯時應(yīng)正裝。

譯文：人們擔(dān)心不僅各類機構(gòu)會因為基因特征的不同而對人挑肥揀瘦，就連作父母的都有可能利用基因來設(shè)計嬰兒——這可以說時把基因知識應(yīng)用到了極端！
