考点 05
描述价格的be动词选择The bread is 12 yuan. 面包12元。
The bag of apples is 12 yuan. 这袋苹果12元。
The apples are 12 yuan. 这些苹果12元。
描述价格时,be动词根据主语的单复数情况决定:
“单数/不可数名词 + is”
The bread is 12 yuan. 面包12元。(主语bread不可数,用is)
“复数 + are”
The apples are 12 yuan. 这些苹果12元。(主语The apples复数,用are)
特别注意 “量词 + of + 名词”作主语时,be动词由量词的单复数决定:
This bag of apples is 12 yuan. 这袋苹果12元。(核心主语是bag,单数用is)
These bags of apples are 12 yuan. 这些袋苹果12元。(核心主语是bags,复数用are)
