A. | are waiting for | B. | is waiting for | C. | is waiting at | D. | are waiting at |
分析 現(xiàn)在有人在學(xué)校門(mén)口等著.
解答 答案:B 考查系動(dòng)詞,根據(jù)句中的Now可知時(shí)態(tài)是現(xiàn)在進(jìn)行時(shí),構(gòu)成 是主語(yǔ)+be+doing,主語(yǔ)someone是單數(shù)形式,故系動(dòng)詞要用is,wait for sb等某人是固定短語(yǔ),故選擇B.
點(diǎn)評(píng) 考查系動(dòng)詞,準(zhǔn)確的分析句子與固定短語(yǔ)用法是解題的關(guān)鍵.
