定义域:
定义域永远是当前函数内变量
x的取值范围，比如
<Object: word/embeddings/oleObject1.bin>
的定义域指的是
<Object: word/embeddings/oleObject2.bin>
的范围，
<Object: word/embeddings/oleObject3.bin>
的定义域指的也是这里边
<Object: word/embeddings/oleObject4.bin>
的范围，而不是
<Object: word/embeddings/oleObject5.bin>
的范围。
1.函数<Object: word/embeddings/oleObject6.bin>
的定义域为（ ）
A<Object: word/embeddings/oleObject7.bin>
B<Object: word/embeddings/oleObject8.bin>
C<Object: word/embeddings/oleObject9.bin>
D<Object: word/embeddings/oleObject ...
