)首先我不知道我做的对不对 帮我看一下,第10题和第11题有什么区别吗,第3题和第9题,some of 后面跟单数或者复数后面跟复数还是单数啊?
还有12和13的区别,我都混了,

Answer 1

votes是负数,不能用三单seems
jury单数,用has
some of the grain,既然是some,应该是复数,不用第三人称单数加s,但我看grain后面没有加s,grain是不可数吗?如果是不可数的话就应该用appears
3/4students,显然是复数,用are,不是is
student body的意思是总体学生,总体学生看作一个个体,所以是单数,用is
high percentage of population,population是不可数,所以用三单,用is
people是可数,所以应该用were,而不是was
