I am sure that you will be successful_you have confidence in the interview

题目

I am sure that you will be successful_you have confidence in the interview
A before B once
Cuntil Dthough

答案

【答案】B
【分析】
这种题目可以用排除法,从意思的角度来分析
before是在……之前,once是一旦,until是直到……,though是尽管
细细推敲一下,A,D选项意思一看就知道肯定不对
C选项可能有点饶人,until单独出现的时候,是直到的意思,放到这句话里,意思就变成了 我确信,你会一直成功,直到你在采访中有自信了.意思恰好和题目所要表达的相反.
选C选项的话,把句子改成I am sure that you won't be successful until you have confidence in the interview.才对
意思是我确信直到你在采访中有自信时,你才会成功
所以只能选B
意思是 我相信一旦你在采访时自信的的话,你将会成功.
