朋友,你好!bear作“忍受”讲的时候,通常这样用,bear+名词或代词:i can't bear him.(我受不了他。)can you bear the words?(你受得了这话吗?)help只有“忍不住”的意思,通常与can't连用,后面接动名词:i can't help laughing.(我忍不住笑了。)she can't help crying.(她忍不住哭了。)懂了吗?没懂再来问我...
be sure of 确信 例句:she looked over her shoulder to be sure of her footing.她扭头看了看后面以确认自已是否站稳了.be sure about 对.很有把握例句:you can be sure about their interest in it.你可以肯定他们对引很感兴趣.
