关于定语从句的重要问题，请速度回答

He is one of the students( )been to China
A.who has B.who have c.which has d.that has
我选了D，老师给我批错了，请问正确答案是哪个，顺便请务必回答下如果句中去掉one和改成the one of，那答案将会是怎么样
说错了--，是加上only 和the only one of，那答案将会怎么样

Answer 1

选B.
解析如下:
(1)He is one of the students( who have )been to China
(句中students为先行词)
(2)He is the only one of the students(who has )been to China
(句中one为先行词)
(1)句与(2)句的本质区别在于定语从句修饰的先行词不同.
关系代词替代的是先行词的内容,所以在其引导的定语从句中,谓语动词的"数"要与先行词保持一致.
补充: 虽然关系代词"that" 既可指人也可指代物,但当关系代词指代人并在从句中作"主语"时,一般要用关系代词Who.因此要是改成提问题所要求的形式.那么答案选A.

Answer 2

1)He is one of the students( who have )been to China
(句中students为先行词)
(2)He is the only one of the students(who has )been to China
(句中one为先行词
one of + 名词复数+定语从句，从句谓语动词为复数。
the only one of +名词复数+定语从句，从句谓语动词用单数

关系代词替代的是先行词的内容,所以在其引导的定语从句中,谓语动词的"数"要与先行词保持一致.
补充: 虽然关系代词"that" 既可指人也可指代物,但当关系代词指代人并在从句中作"主语"时,一般要用关系代词Who.

Answer 3

B

因为这个定语从句修饰的是students

假如把句子改成the one of，那就选A

Answer 4

选B，他是...之一时，谓语动词由the students定，所以是复数。如果改成 only 和the only one of时，谓语动词应是单数，所以应选A。
