(
)There
two bottles of milk in the fridge this morning, but there
any milk left now.
A.was; isn't
B.were; isn't
C.are; aren't
D.were; aren't
点拨 由句意及this morning可推断，前半句的时态是一般过去时，且there be句型中be动词的单复数形式遵循“就近原则”，由空后的two bottles可知，第一个设空处填were；由now可知，后半句的时态是一般现在时，且milk是不可数名词，be动词用第三人称单数形式，所以第二个设空处填isn't。故选B。
答案：B
解析：
1. 前半句根据时间状语this morning可知时态为一般过去时，there be句型遵循就近原则，靠近be动词的two bottles是复数，所以第一个空填were。2. 后半句根据时间状语now可知时态为一般现在时，milk是不可数名词，句中any提示句子为否定含义，be动词用单数否定形式isn't。
[反馈练习]看图，用be动词的适当形式填空，补全短文。
