A recent poll of elected officials suggests that candidates, when in the midst of a tough campaign, often make statements about an opponent that they may not think is true.不说这道题的画线部分,而说这道题的未划线部分when in the midst of a tough campaign,在各种资料上,特别是CD的prep资料都强调when,after,while,although等后面不能接介词短语和名称短语,能接形容词短语,V-ing和V-ed形式,唯一能接介词短语的是once。当然这道题这里并未划线所以无需考虑,可是假如这道题此部分画线呢?选项有a:when in the midst of a tough campaign b:when they are in the midst of a tough campaign 该如何选? |
