问题 Leading politicians in the campaign to pull the UK out of the European Union are changing fast on a number of pledges, particularly over extra money for health care.
选项 A、backlashing
B、backpedaling
C、backfiring
D、backsliding
答案 B
解析    (1)句子结构。
   本句主语中有两个定语：Leading politicians in the campaign (介词短语作Leading politicians的定语) to pull the UK out of the European Union (不定式短语作in the campaign的定语)
(2)选项词义。
A．backlash v.强烈反对；发生后冲
B．backpedal v.改变主意，变卦，背弃诺言
C．backfire v.回火；适得其反；弄巧成拙
D．backslide v.倒退；堕落；背离宗教
句子大意为“在英国脱欧运动中，一些权威政客在许多承诺上一直出尔反尔，特别在医疗卫生增加资金的问题上更是反复无常”。只有backpedal有“改变”这一含义，因此backpedaling为正确答案。
【知识拓展】(1)语法拓展：主语的修饰语。
主语的修饰语可以由介词短语、分词短语或不定式等充当；当主语含有多个不同类型的修饰短语时，要注意识别句子的主干结构。试分析下句中的主语修饰语以及句子主干结构。

学者和政治家们过多强调美国边疆假说，从而掩盖了国际贸易条件的变化及其后果所产生的巨大作用。
   (2)词汇拓展：backpedal与backslide。

   e．g．They promised to cut taxes，but they’re beginning to backpedal now．
