Computer and mobile phones though they are indeed making our life____ and more ___ ,have reduced the need for face-to-face communications.
A easily.efficient
B easier.efficient
C easy.efficiently
D easily.efficiently
答
选b
and 连接两个同样种类的词或词组
既然and 后面是比较级 那么前面也用比较级
还有,不用easily 或efficiently 的原因是 easy 和efficient 是用来修饰our life 的,our life 是名词当然用形容词来修饰.
