In the after-class activities,the students had plenty of______and got a lot of useful __
A.exercises,experiences
B.practices,experience
C.practice,experience
D.exercis,experiences
答案怎会是C
答
practice和exercise做实践锻炼讲的时候既可以做可数名词,又可以做不可数名词,但由只能修饰不可数的plenty of修饰,此处作不可数,因此A,B舍弃
a lot of既可以修饰可数,又可以修饰不可数,但experience作经验讲时,是不可数名词,因此D舍弃
综上选C
