1.D
翻译：大卫还没有来.我认为他会很快露面/出现的.
turn on意思是“打开”；turn off是“关掉”；turn down是“调低音量；拒绝”；而turn up意思是“调大音量；出现/露面”.
2.have changed改成have been changing
句意为“随着时间的的推移,电脑已经改变了很多”.
因为电脑现在还在改变中,所以此句用现在完成进行时是最好的.
3.logical改成logically
因为它修饰动词think,所以用其副词形式.
而logical是形容词,一般修饰名词.

1.D 固定词组
2.have been changed 需要被动
3.logically 需要副词
