{01}_____I always felt I would pass the exam, I never thought I would get an A.
A.While            B.Once             C.If             D.Until
解析：本题考查状语从句。句意：尽管我总觉得能考及格，但我从未想过能得A。在确定状语从句的引导词时，要从上下文的逻辑关系入手，根据语境，“我总觉得能考及格”和“我从未想过能得A”存在转折关系，所以应用“尽管；虽然”来引导，while在此就表此意。
本题选A。
{02}How can you expect him to make any improvement____ you never give him a chance to have a try?

A.unless

B.when

C.until

D.even if

解析：考查连词。此处when意为既然。句意为既然你不给他尝试的机会，你怎么能期望他提高呢。
本题选B。
