A:Your watch looks so new.How long _______?B:Only about three weeks.A did you have it B will you buy it C have you bought it D have you had it
A:Your watch looks so new.How long _______?B:Only about three weeks.
A did you have it B will you buy it C have you bought it D have you had it
A:Your watch looks so new.How long _______?B:Only about three weeks.A did you have it B will you buy it C have you bought it D have you had it
选 D
句意：你的手表看起来如此的新.你买了多长时间了?
大约三个星期吧.
考点：how long 与延续性动词的使用
how long 表示多长时间,要和延续性动词连用
A did you have it 一般过去时,这里问的是买了多长时间了,如果问什么时候买的,应该用
When did you buy it
B will you buy it 一般将来时,手表已经买了,所以不可能是将来
C have you bought it 现在完成时,bought 的原形是 buy 是非延续性动词,不能和 how long 连用
D
根据句意用现在完成时，强调对现在的结果‘ 买了多长时间’排A与B ，而BUY 是终止性动词，不能与HOW LONG 连用。再排除C
加油！不明白再问！如果帮到你，请采纳，谢谢！
正确：D
由How long...？得知，要使用延续性动词。结合前后文，应使用现在完成时。
