选A吧
首先as well as 遵循从远原则,也就是他后面的谓语动词要跟as well as 前面的主语一致,as well as 前面是I,谓语动词应该用am,可排除选项C和D.然后sure为副词,副词是用来修饰动词的,要置于动词前面,因此本题要用sure am,因此正确答案为A.有些人讲副词要放在动词之后,那么请看以下几个例子吧：1.Extremely angered by her remarks,he sued the young man's mother.(Extremely为副词,意为“极其的,非常的” angered为动词anger的被动形式）.
2.I say to those who desperately seek fame and fortune:good luck.
(deseperately为副词,意为“拼命地,绝望地”,seek为动词,意为“寻找”）.
这两句都是正确无误的句子,是我从课本上摘抄下来的,现在你应该知道副词是放在动词之前了吧.
