Question

often后面加什么

Answer 1

often后面一般是加动词的原形形式，表示一般现在时；后面也可以加动词的过去式形式，表示一般过去时。但是如果主语是第三人称的话，那么后面要用动词三单的形式。

具体举例：

1、加动词原形

How often do you brush your teeth?你多久刷一次牙？

2、加动词的过去式

People with the disease were often treated as social outcasts.患有这种疾病的人常被社会摈弃。

3、动词三单形式

A red sky at night often indicates fine weather the next day. 夜空呈红色往往预兆第二天天气晴朗。
