题目内容：

关于英语语法的简单问题,prefer to.rather than 句型
2006年12月新题型的真题中,翻译75题：I prefer to communicate with my customers_____(通过写电子邮件而不是打电话)
答案是via/by email rather than /instead of by phone
or:through writing e-mail rather than/instead of taking over telephone
我想问,by e-mail rather than phone 即than后没有by
修饰的是e-mail 和 phone 那样,我是这样理解咯,

优质解答

by e-mail rather than phone
不行.
rather than 是并列联词的,
两边要对等.
不能省.
