Question

【题目】_______is known to us all is that Johnson broke his promise ______ he would come to help me as soon as possible.

A. It; thatB. What; thatC. As; whichD. What; which

Answer 1

【答案】B

【解析】

考查名词性从句。句意：我们都知道，Johnson违背了他会尽快来帮助我的诺言。分析句子结构可知，第一空为主语从句，从句中缺少主语，所以用what，第二空为同位语从句，从句结构完整，所以用that解释promise的内容，故B项正确。
