【正确答案】 B

【答案解析】该题是词汇题，考查名词的意义和用法。 根据句子意义，选项A中的production(生产)和选项D中的calculation(计算)可以首先排除。选项B和选项C均表示“预见”，但它们用法不同。选项B中的forecast意思是“a statement about what will happen in the future, based on information that is available now”，如：Statistical analysis is a means of arriving at a fairly reliable forecast.根据数据分析做出的预测相当可靠。而选项C中的anticipation意思是“the fact of seeing that sth. might happen in the future and perhaps doing sth. about it now”，如：We bought an extra supply of coal in anticipation of cold winter. 估计会有寒冬，所以我们多买了一些煤。因此，选项B为最佳答案。
