For example, if I am on Monday and I've already done everything I need for class one on blue days and I didn't have anything for class two, I finished my class three things, blah, blah, blah, then I would check them all off this way.
例如,如果我在星期一,我已經做完了藍天第一課需要做的所有事情,第二課沒有任何事情,第三課的事情我也做完了,等等等等,那麼我就會這樣把它們全部勾掉。
