Question

【題目】I have to see the doctor because I ________ a lot lately.

A. have been coughing B. had coughed

C. coughed D. cough

Answer 1

【答案】A

【解析】試題分析：考查動(dòng)詞時(shí)態(tài)。句意：今天下午我必須得去看醫(yī)生因?yàn)槲医�期總是咳嗽。把握關(guān)鍵詞：recently，近期，用于現(xiàn)在完成時(shí)，排除B C 和D ， A. have been coughing現(xiàn)在完成進(jìn)行時(shí)，強(qiáng)調(diào)動(dòng)作持續(xù)不間斷，說(shuō)明咳嗽的嚴(yán)重，所以A正確。
