问题：一道单选题
He left____wh my secretary that he would call again in the afternoon.He said he would keep___.A words,his wordsB word,his wordC a word,his wordD the word,his word解释一下好吗？另外顺便问 What does the coat cost?这句说法对不对？
回答： 
答案B无疑。
word表示“信息、消息”时是不可数的；而且不用冠词。that从句是它的同位语。老教材“拿破仑的三个问题”里有这么一句：Word came that ......。
keep one's word守信
“What does the coat cost?”表达方式的不合理，并不在于What，而是cost。就价格而言，动作发生后才用cost来表达。What did the coat cost?
当然，从名词用法看又当别论。What is its cost?是可以的。
