顺便帮我解析一下谢谢(不要一面子一面子的复制,我没那么多时间看),
英语问题Not until he retired from teaching three years ago .
D
not...until...的倒装句型,即:Not until + 时间状语(从句)+ 句子主干/主句(部分倒装).
此句正常句序为:He didn't consider having a holiday abroad until he retired from teaching three years ago.
部分倒装就是把句子的be/助动词/情态动词提到主语之前,类似于一般疑问句的变化.
AC没有倒装,而且主句为一般过去时,而不是过去完成时,再把B排除.
D
固定句型:It is high time that从句,意思是“到了...的时候了”.
该句型中要求that从句采用虚拟语气,即从句使用一般过去时或谓语由"should + 动词原形"构成.
所以答案为:should do 或 did,所以答案D为正解.
