网友回答
A. walking in; to read
B. ing in; reading
(答案→)C. entering; to be reading
D. entered for; to have read
解析:考查分词补足语和不定式用法。第一空考查了see sb doing sth看见某人正在做某事;本句中的the teacher与enter之间存在着主动关系,故使用现在分词的形式。第二空考查了pretend to do sth假装做某事;如果事情是正在发生的事情,就使用pretend to be doing sth假装正在做某事;句意:看见老师进入教室,孩子们假装在读课文。故C正确。
