(
)Mike
draw when he was five, but now he
draw well.
A.couldn't; can't
B.can't; can
C.couldn't; can
D.can; can
点拨 由 when he was five 可知,前半句的时态是一般过去时,所以排除选项 B、D;句中的 but 是转折连词,所连接的前后两个句子的意思相对,此句句意为“迈克五岁时不会画画,但他现在可以画得很好”。故选 C。
答案：C
解析：
1. 根据时间状语when he was five可知前半句是一般过去时，情态动词需用过去式，排除使用现在时态的B、D选项；2. 句中but表转折，后半句时间为now，表达现在他能画得很好，用情态动词can，排除A选项，最终确定答案为C。
