undoubtedly和 doubtless（ly）有区别吗？

注 doubtless 本身也有副词，doubtlessly也是副词……

有区别。 undoubtedly指的是无疑;毋庸置疑地，的确地;显然;必定。 doubtless指的是无疑地;确定地;多半。 例句辨析： undoubtedly 1、mr brooke is undoubtedly in a spot of bother. 布鲁克先生肯定遇到了点小麻烦。 2、mozart's compositions are undoubtedly amongst the world's greatest. 莫扎特的作品无疑位居世界上最伟大的作品之列。 3、burke's sentiments undoubtedly struck a responsive chord in parliament. 伯克的观点无疑引起了议会的积极回应。 doubtless 1、he will doubtless try and persuade his colleagues to change their minds. 他很可能会试图说服同事们改变主意。 2、doubtless he was justified in some of his criticism of the media. 他对媒体的一些批评性言论无疑是合乎情理的。 3、she took off her shoes, doubtless because her feet hurt. 她脱掉了鞋子，大概是因为脚疼。
