Computers 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
为什么选B不选C
答
make sth more and more adj.
所以选择形容词的比较级 B
答
选easier,是因为后面的more提示了前面的中文意思有比较,即“更容易”；
选efficient,是因为more后面一定要加形容词,即efficient(有效率的).
以上.
