Helen’s parents( )teachers in our school.A.are each B.each are C.both are D.are both(说理由)
Helen’s parents( )teachers in our school.
A.are each B.each are C.both are D.are both(说理由)

both表示两个人,parents是两个人所以用are
答案:D

D teachers是复数,所以用both,parents也是复数,所以用are
be 动词和both all 连用时,放在be 动词前,也就是are both

1.题中有“parents”是复数,应用both,排除A和B
2.are只能放在both之前,排除C
答案选 :D

D 父母是两个人用both,A,B不对,因为be both···所以C不对,所以选D
