Well, one of my favorite sayings from philosophy is cognito ergo sum, which means to be, I think therefore I am B is an irregular verb that sometimes difficult for people because it can be used for description as well as action in the continuous form present, continuous, past, continuous and future, continuous when you add I N G.
好吧,我最喜歡的一句哲學名言是cognito ergo sum,意思是to be,I think therefore I am B是一個不規則動詞,有時對人們來說很困難,因為它可以用於描述以及行動的連續形式,現在、連續、過去、連續和未來,當你加上I N G時,就是連續。
