1.every＋基数词(大于或等于2)＋复数名词 意思是每.例如：
We hand in our homework every three days.我们每三天／每隔两天交一次作业
2.every＋序数词(大于或等于2)＋单数名词意思是每.例如：
He comes to see his uncle every third week.他每三周／每隔两周来看望他的叔叔
3.every other ＋基数词(大于或等于2) ＋复数名词 意思是每隔.例如：
I have to work out every other two days.我每隔两天就要作一次运动
4.every other ＋零基数词(等于1)＋单数名词 意思是每隔一天例如：
Take this medicine every other day.这药每两天／每隔一天服一次
5 every few + 复数名词 每隔几：
He came to see me every few days.他每隔几天来看我一次.
互换：
Mary goes to see her grandparents every three days/every third day/every other two days.玛丽每三天／每隔两天去看望她祖父母一次.
注意：
every和each虽为同义词,但在表达“每隔……”时,不能用each来替代every.
故正确答案为C,每四个小时/每隔三个小时
祝开心~!
第三个
由日常生活道理得知，服药时间是每隔多长时间一次的，所以选C（每隔4小时）。
希望对你有帮助。
C
every four hours每四个小时一次
once a hour 一小时一次
twice a hour 一小时两次
C 每4个小时 应该没有each four hours 这种表达
C
every four hours每四个小时一次
once a hour 一小时一次
twice a hour
