三次以上英语

twice a week or three times a week or four times a week

once一次twice两次三次以上就是数字加times然后现在完成时是 have+过去分词过去完成时才是 had+过去分词楼上错了

Two or three times

twice a week 2次three times a week 3次four times a week 4次n times a week n次

once,twice ,三次以上都是 : 序数词+times如（thress times, four times)现在完成时： have done 现在完成时的 否定OR 疑问 have you done ... yet? I haven't done ....yet.希望对你有帮助~

two to three times.

每周两次 twice a week每周三次 three times a week每周四次 four times a week一次两次用once twice三次以上就用 （three） times

一次once ，两次twice，三次以上用....times，但两到三次应该用two or three times
