—Where is your sister?
—She          the flowers now.
A．watersB．wateredC．has wateredD．is watering
D

試題分析：句意：你的姐姐在哪兒？——她現(xiàn)在正在澆花。結(jié)合語(yǔ)境可知下文描述的是現(xiàn)在正在進(jìn)行的動(dòng)作，故用現(xiàn)在進(jìn)行時(shí)態(tài)，選D。
點(diǎn)評(píng)：英語(yǔ)中的時(shí)態(tài)主要是借助于時(shí)間狀語(yǔ)與上下文語(yǔ)境來(lái)進(jìn)行判斷。解答此類題型，首先要注意句子中的時(shí)間狀語(yǔ)，如果沒(méi)有則要通過(guò)分析上下文，結(jié)合語(yǔ)境來(lái)判斷句子的時(shí)態(tài)。英語(yǔ)疑問(wèn)句中一般具有時(shí)態(tài)上的對(duì)應(yīng)關(guān)系，注意結(jié)合這一特點(diǎn)進(jìn)行區(qū)分。
