27. It is no good simply keeping him from doing what he wants to.
A.一直让他随心所欲，这种做法真是太恶劣了。
B.轻易地阻止他做自己想做的事起不到丝毫作用。
C.一直让他随心所欲这种做法虽容易，却一点都不好。
D.仅仅只是阻止他做自己想做的事，一点用处也没有。
【解析】D。it is no good doing sth.，意为“做某事不好”，另一个结构是keep sb. from doing sth.，意为“阻止某人做某事”。此外simply在此处意为“仅仅”，与simple(简单的，轻易的)意义有出入。基于以上分析可知，四个选项中选项D的翻译最贴近原意。选项B未能结合上下文，错将simply译为“轻易地”，因而不妥;选项A错将keep sb. from sth. 理解为keep sb. doing sth.将其译为“一直让他……”同时该选项还简单地按字面意思将no good译为“恶劣”。故不及选项B;选项C的译文则是完全脱离了原句的句法结构，不过是对原文中个别单词意思的随意组合，最为不妥。
