----Will $ 1,000 the cost of the trip?

----I’m afraid not. Perhaps I need $500.

A. pay; another

B. charge; more

C. cover; another

D. afford; more

答案：

A. pay; another

B. charge; more

(答案→)C. cover; another

D. afford; more

解析：句意“1000美元够旅行的费用吗？”“恐怕不够，也许还需要500美元。”charge“收费”；cover“包括”；afford“买得起”。根据句意可知，用cover；在原来的基础上再多一些用“another+数词”或“数词+more”表示，这里用another。故选C。
