My hobby is collecting stamps．I need before I have 3000 stamps．

A. more one

B. any more

C. one more

D. more than

答案：

A. more one

B. any more

(答案→)C. one more

D. more than

解析：

试题分析: 句意：我的爱好是集邮，我再要一个就够3000张邮票了。more one无此用法，any more再，one more再来一个，more than比……多；根据before I have 3000 stamps在我有30000张之前，可知是差一张够3000，故选C。
