exciting news! We’ve never had long vacation before.
A. What; such a
B. What an, such a
C. How; so
D. What ; so a
答案:
(答案→)A. What; such a
B. What an, such a
C. How; so
D. What ; so a
解析:句意:多么令人兴奋的消息!之前我们从没有如此长的假期。感叹句中消息是不可数名词,用what引导;假期是可数名词用such来修饰。What+a(an)+(形容词)+单数可数名词+主语+谓语!. What+(形容词)+可数名词复数或不可数名词+主语+谓语!how用来修饰形容词、副词或动词。其结构是:How+形容词(副词)+主语+谓语!故选A.
