大家帮我看看这个句子的结构?
A and B tell me that they have been expecting a splendid crop this yearand harvesting has began earlier than usual .
时态不懂啊
大家帮我说说have been expecting a spiendid cropharesting has began earlier 是什么时态啊?
为什么一个用have一个用 has呢?
has began为什么不是has begun呢?后者是被动吗?
答
they have been expecting a splendid crop this year and harvesting has began earlier than usual.是两个并列的完成时态的句子,作that的宾语.整句话是一个宾语从句.have been expecting的主语是 they,has begun的...
