否定句和疑问句用any,肯定句用some,如果你期待否定回答要改成any; 但是如果你期待别人给出肯定回答,或者用附加疑问句就要用some,如:
1 Do you do any reading in your spare time?你课余时间不读书吗?/你课余时间读不读书啊?(有一种怀疑的态度)
2 will you do some reading in your spare time?你有空的时候会阅读吧?(态度柔和的询问)
3 You do some reading in your spare time,don't you?你有空的时候会阅读的,对吧?(自己已经认为答案是肯定的了,只是想确认一下)
因此,本题可以改为any 选a .译为:佳明昨晚根本没读书.any,表示了一种否定的态度.
