"If I hadn't pratised when I was younger,” the musician says,"I____able to play so well now."

I

hadn't

pratised

when

I

was

younger,”

the

musician

says,"I____able

to

play

so

well

now."

為什麽答案是"

wouldn't

be

"而不是"

wouldn't

have

done

"？

這是因為：從句和主句的時間不壹樣，從句是與過去的事實相反，用過去完成時，而主句的時間是now，現在，所以應該與現在的事實相反，用與現在事實相反的wouldn't

be
