。
例如:

Why do people usually make resolutions?

They hardly ever watch TV.
Fewer people will do such jobs in the future because they are boring, but robots will never get bored.
二、用法
1 、 often, always, usually 等通常和一般现在时连用,表示现在经常或反复发生的动作。
如: It often rains here in April. 这儿四月份常下雨。
2 、对这些频度副词提问时,用 how often 。
如: ---How often do you write to your brother? --- Three times a month .
--- 你多久给你哥哥写信一次? --- 每月三次。
【注意】
“ 次数”的表达方法:
1 、一次 once ,两次 twice ,三次或三次以上用基数词加上 times : three times (三次), five times (五次),
one hundred times (一百次)
2 、表示 “……几次” 的表达方法是:
once a day/a week/a month/ a year (一天 / 一周 / 一年一次)
twice a day/a week/a month/a year (一天 / 一周 / 一月两次)
time 表示不可数名词,意为 “时间”;表示可数名词,意为“次数,倍数”
