----they often ----(play)football at this time of day?yes,they----.问填Do 和play对还是are和playing对?Do they 和Are they在这里开头用法的区分,和什么时候该用Do they,什么时候用Are they,还有我说的这两个答案是不是都可以填?

Do they 和Are they在开头用法的区分----they often ----(play)football at this time of day?yes,they----.问填Do 和play对还是are和playing对?Do they 和Are they在这里开头用法的区分,和什么时候该用Do they,什么时候用Are
这个题应该用DO PLAY.are playing在这里不能用.
be doing用在现在进行时的句子中,而do doing表示一般进行时.
often决定了这个句子为一般现在时,而不是现在进行时,翻译全句为:他们经常在每天的这个时间踢足球吗?如果要使用ARE DOING,则句子要改成:Are they playing football at this time?他们现在在踢足球吗?

答案是Do they,因为用的是OFTEN这说明是一个经常性、习惯性的活动,Are playing更加侧重于在一天当中的这个时间正在做什么。OFTEN与一般现在时连用,很少会与现在进行时连用。

用Do说明后面的动词是一个行为动词,需要借助助动词do表示疑问或否定
用are 说明后面是一个形容词或名词,需要用系动词作谓语
你的题目应该Are playing,因为后面的at this time是指现在,所以用进行时态
