答
这个具体要看前面的那个动词的用法，比如：
she often starts reading at 7:00am。（她通常在早上7:00就开始读书）
she often goes shopping。（她经常购物）
she often wants to return her childhood。（她经常想回到她的童年时代）
希望帮助到你，学习进步。
答
often do sth， often 是频度副词，do sth 就是句子的谓语宾语，谓语不用 to do 或 doing sth 非谓语形式
答
often do
不过这不是固定词组噢!
often 是频率副词
只要把它加在原来的句子中动词前面就可以了
原句 I watch movies at weekends.我在周末看电影
加入 I often watch movies at weekends.我经常在周末看电影
加了often可以更清楚地表示出频率
对句子本身没有任何影响
答
do，表示经常做某事的都用do，还有像always,usually.....
