【題目】Ellen has already bought some flowers. (改為否定句)

Ellen________ bought any flowers________

【答案】hasn’t yet

【解析】

句意:艾倫已經(jīng)買了一些花。

根據(jù)句子結(jié)構(gòu)分析及改寫要求可知,原句用的是現(xiàn)在完成時(shí),結(jié)構(gòu)是have/ has+過(guò)去分詞,所以變成否定句時(shí),直接在have/ has后面加not,而原句肯定句中用的是already,所以變成否定句時(shí)要用yet,故答案為hasn’t,yet。
