题目内容
7.-How long have you_______?-For three days.( )
| A. | got a headache | B. | fallen ill | C. | caught a cold | D. | had a cough |
分析 你咳嗽多久了?三天了.
解答 答案:D 根据答语中的for three days,判断本题应该用现在完成时态,现在完成时态的结构是have/has+动词的过去分词,再结合本题 for three days 动词应该用延续性动词,而在本题中get,fall,catch 是非延续性动词 故排除A,B,C只有have是延续性动词故选:D.
点评 做这类题注意区分现在完成时中延续性动词与非延续性动词用法.
