Question

10．昨天因为交通拥堵，他们开会迟到了．
They were late forthe meeting because of the heavy traffic yesterday．

Answer 1

分析 They were late for．

解答 答案：They were late for．结合句意表达的是过去的事情用一般过去时，表示因…迟到用be late for，后可加名词，主语they复数，故were，故答案是They were late for．

点评 be late for 因…而迟到，做…迟到．后接名词．例：
I will not be late for school．
我上学不会迟到．
I'll be late for the meeting．
我开会要晚了．
be late to 后接的是动词，表示做这个动作稍晚，迟．例：
"Why were you late to school this morning？
"今天早上你为什么上学迟到？"
