A. add up

Badd up to

C. add to

D. added up

答案：

(答案→)A. add up

B. add up to

C. add to

D. added up

解析：考查动词短语的区别。A 把加起来；Add up 3, 4 and 5 and youll get 12. 把三、四、五相加,总数是十二； B 总共，总计；The bills add up to exactly $100. 这些帐单加起来正好一百元。 C 增加；the bad weather add to our difficulties D 把加起来；根据句意：你最好把你的分数加起来，看看是否通过考试。Had better后面接动词原形，故A正确。
