（ ） 10.What she says and does _____ nothing to do with me.A.was B.were C.has D.have（ ）12.Nobody ______ seen the film.It’s a pity.A.but Tom and Jack have B.except Tom and Jack haveC.but my friends has D.but I have

10 C,1.have sth to do with固定词组；
2.主谓一致，What从句应看作正体。
12 C,But有*就前原则*。
具体说就是当主语是 A but B 这种结构时，谓语动词与A一致。
如果A是复数，谓语动词就是复数。
如果A是单数，谓语动词就是单数。与B是单数、复数无关。
与这这种结构类似的还有：
as well as
rather than
along/together with
but
except 等

谓语动词都是和词组前的那个单词一致。

10.C
What she says and does 是一个整体，所以谓语用单数形式
have nothing to do with 与什么无关
have something to do with与什么有关
12.C
but,as well as,except连接代词或名词做主语时，谓语与这些词的前面的名词的单复数形式保持一致

1.C (have/has nothing to do with sb.是一个固定词组,What she says and does 作为一个整体看待,故用HAS）
2.C（中心词之后有but ,except,with ,as well as 修饰语时,谓语动词的数与前面的中心词保持一致）

（ C ） 10. What she says and does _____ nothing to do with me.
A. was B. were C. has D. have
What引导主语从句作整个句子的主语，句子的谓语动词用单数，且have something to do with sb.是固定结构
（ C ）12. Nobody ______ seen the film. It’s a pity.
A. but Tom and Jack have B. except Tom and Jack have
C. but my friends has D. but I have
当主语是 A but B 这种结构时，谓语动词与A一致。A是复数，谓语动词就是复数。A是单数，谓语动词就是单数。不管B是几个名词。
与这这种结构类似的还有：
A as well as B
A (together)with B
A but B
A except B
谓语动词都是和A一致的。
