1. Does he looks like his father?
2. He likes play games after class.
3. Miss Gao teachs us English.
4. She doesn't her homework on Sunday.
5. There have forty students in our class.
簡析： 1. looks改為look，助動詞用does已表達出該句謂語動詞是第三人稱單數，其后面的行為動詞應用原形。
2. play改為playing， play games是動詞短語，不能做動詞like的賓語。動詞做賓語時，應當用to do或doing形式。如：He likes swimming but I like dancing.
3. teachs改為teaches，以字母s, x, sh, ch等結尾的動詞用于一般現在時第三人稱單數，動詞要加es;以輔音字母+y結尾的動詞，先變y為i再加es, have的第三人稱單數為has，這些特殊的變化規則應該牢記。
4. 句中的does是構成否定的助動詞，后面還必須加上一個行為動詞do。
5. have改為are，本句將There be...句型與have混淆。There be...句式中的be不能用have(has
