频率副词在不定式中的位置

问题描述

不定式短语含有频率副词时，请问频率副词放在什么地方，例如：

(1) To walk often can make us happy.

(2) To often walk can make us happy.

(3) Often to walk can make us happy.

哪个对？谢谢！

老师答疑

沅老师：

你的三个句子正误如下：

(1) To walk often can make us happy. (正)

(2) To often walk can make us happy. (误)

(3) Often to walk can make us happy. (误)

频率副词通常不放在在不定式中间（to与动词原形之间，否则构成所谓的分裂不定式），也不放在不定式前面，而是放在不定式的后面。再如：

What he likes best is for her to call often. 他最喜欢的是要她常给他打电话。

Drinking too much often results in a loss of libido. 饮酒过度经常会导致性欲丧失。
