问题 The police asked the children ______cross the street ______the traffic lights turned green.
选项 A、not; before
B、don’t; when
C、not to; until
D、not to; after
答案 C
解析 考查时间状语引导词和固定短语ask sb．to do sth．的否定形式。ask sb．to do sth．的否定形式为ask sb．not to do sth．，由此可排除A、B。四个选项中before，when，until和after均可以引导时间状语从句，但D中after用在此处意为“绿灯亮了后不要过马路”，不符合生活常识。C中until与not连用，表示“直到……才……”，为正确答案。
