e.g. My mother often goes to work by bus.
We like playing basketball.
動詞第三人稱單數變化：
look - looks, like - likes
play - plays, cry - cries
go - goes, do - does
watch - watches, wash - washes
have - has
知識點歸納：
一般現在時（動詞為be）
肯定句：be動詞具體變為am/is/are
（單數is，復數are，I用am，you用are）
否定句：be后加not，即寫isn't，aren't，am not
一般疑問句：Be提到句首，加?
I am... 或 We are...要改為 Are you...?
劃線提問：疑問詞+be, 加?
一般現在時（動詞為實意動詞）
主語為第三人稱單數
肯定句：主語+動詞加s或es+其他+.
否定句：主語+doesn't+動詞恢復原形+其他+.
一般疑問句：Does+主語+動詞恢復原形+其他+?
劃線提問：疑問詞+doe+主語+動詞恢復原形+其他+?
主語為其余人稱和數（即主語不是第三人稱單數）
肯定句：主語+動詞原形+其他+.
否定句：主語+don't+動詞原形+其他.
一般疑問句：Do+主語+動詞原形+其他?
劃線提問：疑問詞+do+主語+動詞原形+其他+?
