Outside the school ________ crowds of students, ________ to know the results of the exam．

A.stand; too anxious

B.stand; too excited

C.stands; very worried

D.stands; eager enough

答案及解析： A

解析：

此句是一个完全倒装句，其原因是Outside the school表示方位，提到句首，该句则要用完全倒装句式。too anxious to know the results of the exam是形容词短语，作主语补足语，表示主语的状态。注意too anxious to know意为“太急于知道……”；

而too excited to则为“太兴奋了，以至于……”。
