I'd appreciated hearing from you ____ telling me how everyone is getting along选择题这里该写什么题目As I'll be away for at least a year, I'd appreciated hearing from you ____ telling me how everyone is getting along选项A. sometimes, B. o
now and then可以译为偶尔,这句话的大意是我至少要离开一年,我希望偶尔收到你的来信告诉我大家过得怎么样,而always,sometimes的意思不太合适,often一般位于实义动词之前,助动词之后,所以now and then最好

这里只有D是“间或”、“时而”的意思，其它三个选项中的词显然没有这个意思（A：有时，B：经常，C:总是），故应该选D。

A有时.B经常.C总是.D偶尔，间或
