錯(cuò)了唄.
答案應(yīng)該是is standing,is sitting.第一句交代了時(shí)間,now.應(yīng)該用進(jìn)行時(shí).
寫書的人他也不是神仙啊.他自己認(rèn)為是正確的,其實(shí)不然.
按答案
Our teacher doesn't stand up right now.
這句話,怎么理解?顯然是不通的.
而后文,She is sitting on the conner of her desk.
她正坐在她桌子的角上.這老師也夠淘氣的了.暫且不提,這句話,用了進(jìn)行時(shí),根據(jù)是什么?顯然根據(jù)前句的right now.
第一句也應(yīng)該用進(jìn)行時(shí).
涉及到現(xiàn)在字眼的句子中,謂語(yǔ)動(dòng)詞用一般現(xiàn)在時(shí)的動(dòng)詞,是want,need,這樣的,比如.
She doesn't want to stand up now.
She needs to stand up now.
stand,做位于動(dòng)詞,時(shí)間是now,必須用進(jìn)行時(shí).
