confidence 是抽象名词吗

问题描述:

confidence 是抽象名词吗
1 .in that situation,_spirit of confidence can be more useful than crying for help.填冠词并说明原因
2.the study,_ in beijing and 5 other big cities ,suggests that 百分之75 students have problems communicating with parent.
A conducting B conducted C having conducted

the 特指的是自信的精神
B 这里只能选非谓语动词,因为主语是the study 谓语是suggests ,并且ing表示主动,ed表示被动,所以 主语和_ in beijing and 5 other big cities 是被动的,应该选B.不选C,是因为这是一个陈述事实的,不用have的完成时.若have 理解成有的意思,也是不对的.所以只能选B.
confidence是看不见的,是抽象名词,一种内在的品质 courage,勇气的意思,就是抽象名词,一个意思,明白了吗?但是第一个答案是a啊
