问题解答:

我来补答
was not helpful at all
因为前面是一般过去时,要保持时态一致.
再问: having conversations with friends 是were还是are not helpful at all 后面是动名词作主语啊 宾语从句都要保持时态一致吗
再答: 对。 首先having conversations with friends是一个整体,应该用单数。 然后She added主句是一般过去时,所以要同样保持时态一致。
再问: 那主语是having,还是having conversations with friends
再答: having conversations with friends
