言小旭他妈
1.twice 两倍B选项错在比较级中不用倍数词(理由很简单sthA是sthB的几倍,当然是在sthB原级基础上的几倍了,不然又如何衡量几倍关系昵.所以即便是要表达两倍多那也应是more than twice )2.take questions 回复问题 (注:这里questions用要复数形式)1)Now I'll be happy to take questions from you. You may raise your hands.现在我愿意回答同学们的问题，大家可以举手提问。2)Before I take questions from you,I hope everyone keep silence.在我回答各位提问前，我希望大家保持安静.If you still feel confused,leave a message please祝学习进步!!!
