问题详情：
His successful experience on calculating the distance _______ an interesting topic to discuss.
A raised B rose C was raised D was risen
【回答】
A. 此题考察动词 raise与rise的辨析。
raise 为及物动词，意为“举起……；引起”；rise为不及物动词，意为 “升起”
及物动词后面需要宾语；不及物动词后面不能加宾语，所以及物动词有被动语态；不及物动词没有被动语态。
如：The students are raising the national flag. The sun rises in the east.
根据题干， “an interesting topic to discuss”为本句的宾语，且本句没有表达被动含义，raise在此句中意为“引起”，故选A.
知识点：动词语态
题型：选择题
