7．_____ of my parents is poor-educated，they both left school when they were 13.
A. Both B. All C. Either D. Neither
选什么 ，为什么

Answer 1

C
all是指三个或三个以上，而both是指两个；
both of两者都
Both of them are students. 他们俩都是学生。
all of三个或在三个以上都
All of us are going to see the game. 我们都要去看比赛。
either of (两者其一)
neither of(两者都不)
这两个后＋单数

both of (两者都)，后＋复数

all of (三者或三者以上都是)
这道题因为 is poor-educated，如果Is改成are的话肯定选A，但是是Is,只能选C了。

Answer 2

C. Either

Answer 3

a

all是三者或以上。

neither.两个都不。

neither两者中任何一个

Answer 4

谓语is单数，用Neither
译为：父母都不教育程度差，因为他们13岁才离开学校
表示“两者都不.....”用.Neither

选D
