D．It was not until I reached London that did I realize that my English was so poor.
答案
答案：D
题目分析：考查强调句型和倒装句。当否定词放在句首的时候，后面的主句要使用部分倒装的形式。B项正确。C项是正常语序的not…until…用法；A项是正常语序的强调句型。在强调句型中也要使用陈述语序。故D项错误。
点评：强调句型中都要使用陈述语序，首先要知道强调句的结构It is/was+被强调部分+that/who+句子的其他成分，如果被强调的部分是人，可以用who代替that。具体是用is还是 was，要根据具体的时态确定。强调句的用法及判断：如果把句子中的It is/was…that去掉，稍加调整语序，能还原成完整的句子，并且句子意思依然完整，则为强调句型，否则为其他从句。我们应熟记这些基本规则。
