            confident, convinced, curious, doubtful, positive, sure, unaware, 
            willing 等,如:
 We are confident that we will be able 
            to get the work done in time.
   这些形容词有些可直接带疑问词引导的宾语从句,也可和介词组成短语形容词再接宾语从句,如:I am not clear (about) where they 
              live.
 Are you sure (of) how much the computer 
              costs?
   2.表示心境和情绪的形容词可接that引导的宾语从句表示原因(口语中that常省去)。跟这种从句的形容词很多,常见的有:afraid, 
              annoyed, ashamed, content, delighted, disappointed, glad, hurt, 
              pleased, proud, satisfied, sorry, surprised等,如:I am sorry (that) you cannot stay 
              with us.
