解答:

57. I ______ my classmates while they often fight.
  A. got on well with B. gets on with
  C. get on well D. get on well with
D 和某人相处的融洽
时态前后要呼应,后面一般现在时态,所以前面也是.
I 不能和单数动词连用,排除了第2个
 64. There ________ great changes in computers in the last few years.
  A. have had B. have C. have been D. has been
C 时态 用现在完成时态,因为有in the last few years.
其次表示有变化用THERE BE 不用用HAVE
