频率副词always(总是), usually(通常), often(经常), sometimes(有时候), 还有hardly ever(几乎不), never(从不),谈论习惯性、经常性的动作或状态，常常与一般现在时连用。
例如：他总是上课迟到。He always arrives late for class.
她通常晚上做家庭作业。She usually does her homework at night.
他们几乎不看电视。 They hardly ever watch TV.
What do you usually do on weekends I always exercise.
What do they do on weekends They often help with housework.
What does she do on weekends She sometimes goes shopping.
发现二
在一般现在时的特殊疑问句中，当主语为第一人称、第二人称或第三人称复数时，在疑问词后，主语之前加助动词do, 当主语为第三人称单数时，在疑问词后加助动词does, 其句型结构为：
①特殊疑问词+do+主语(第一人称，第二人称，第三人称复数)+动词原形+其他？②特殊疑问词+does+主语(第三人称单数)+动词原形+其他？
例如：How do they get to school What time does she get to school
特殊疑问句的答语句型结构为：
①主语(第一人称，第二人称，第三人称复数)+动词原形+其他。
②主语(第三人称单数)+动词原形加(s\es…)(三单形式)+其他。在一般现在时的一般疑问句中，助动词do\does要放在句首。如：他们通常在周未锻炼吗？
___ they often _______ on weekends
她一周上网二次吗？____ she ____ the Internet twice a week
Do exercise
