54,it was not ______ he took off his dark glasses ______ I realized who he was.
D,until ,that
这是 对 时间状语 强调的 强调句型 不能选A 因为有not
正常 语序是 I didn't realize who he was until he took off his dark glasses.
倒装句是 not until he took off his dark glasses did I realize who he was.
强调句 就是本句
,55,mother was worried because little Alice was ill,espically ______ father was away in france.A,as 当……时候 用 while 也可以
选项C 是介词 后面 不能跟句子
其他选项 都不能 作时间状语
