选项 A、otherwise
B、which means
C、generally speaking
D、that is to say

答案 D

解析 语篇衔接题。由句意可知,后面句子是对前面句子的进一步解释说明,因此选[D]that is to say(也就是说)。[A]otherwise意为“否则的话”,排除;[B]which means意为“也就是说”,从意思上来说,which means可以作为选项,但是因为前面的标点符号为分号,而which means是非限制性定语从句,只能用在逗号后面,故排除;[C]generally speaking意为“一般来说”,不符合此处的逻辑关系,故排除。
