Answer 1

A
试题分析：考查强调句型。本题强调的是施加状语从句not
until
I
failed
in
the
exam，在强调句型中，后面的句子要使用陈述语序。句意：直到我在考试中又一次不及格了我才意识到自己浪费了多少的时间。故A正确。
点评：首先，要知道强调句的结构It
is/was+被强调部分+that+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，一般说来，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。
