问题补充：

— good news he brought us yesterday!

—Yes, all the students were very excited．

A. What a

B. What

C. How

D. How a

答案：

A. What a

(答案→)B. What

C. How

D. How a

解析：本题是感叹句，修饰的单词是名词，通常用what，news是不可数名词消息的意思，所以无需加冠词，若名词为可数名词单数需在前加不定冠词，元音音素用an，辅音音素用a，感叹句中how后跟形容词或副词，与本题不符，而后半句time加冠词a表示一段时光的意思，故本题选B。
