1:Questions and exercise are given by the computer ,which decides to move
the students ahead ,review an easier level,give more work on the same level.
A;either ,or B;whether or
2:you are in out ,it makes no different.
A;either ,or B;whether or
either ,or 也是多选一【一般多用于二选一】的意思,为什么不选它?
第1题:either...or...用于两者选一,而题目中有三个可能(1.ahead 2. review an easier level 3.give more work)所以不能用either...or.
第2题:Whether...or... 可引导从句,而either...or...是并列连词,不能用来引导从句.所以只能用Whether...or... .
