how+old+is大明为什么用is?

答：因为大明（ Daming）他是属于第三人称单数。主、谓语的一致性要求，本句子中的be动词必须要用is. 即：Excuse me, how old is Daming?

否定 Daming isn't twelve years old. 大明不是12岁 It isn't Daming who is twelve years old. 12岁的不是大明。疑问 How old is Daming? 大明几岁？Is Daming twelve years old? 大明12岁么？

句意：玲玲12岁。twelve十二，对年龄提问用how old几岁，故答案填How old小题4:考查否定句。句意：桌子上有一些花。肯定句变否定句加not，some变any,故答案填aren’t any小题5:考查汉译英。大明Daming,在哪儿where,主系表结构，根据Daming，可知系动词为is,故答案填Where is。
