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(dòng)詞用does已表達(dá)出該句謂語動(dòng)詞是第三人稱單數(shù)，其后面的行為動(dòng)詞應(yīng)用原形。
2. play改為playing， play games是動(dòng)詞短語，不能做動(dòng)詞like的賓語。動(dòng)詞做賓語時(shí)，應(yīng)當(dāng)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(jié)尾的動(dòng)詞用于一般現(xiàn)在時(shí)第三人稱單數(shù)，動(dòng)詞要加es;以輔音字母+y結(jié)尾的動(dòng)詞，先變y為i再加es, have的第三人稱單數(shù)為has，這些特殊的變化規(guī)則應(yīng)該牢記。
4. 句中的does是構(gòu)成否定的助動(dòng)詞，后面還必須加上一個(gè)行為動(dòng)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
