下图中的半岛及东部、北部海域为某国的主要范围，据此完成下列各题。

如图：正方体$ABCD-A_1{B}_1{C}_1{D}_1$，棱长为1，黑白二蚁都从点$A$出发，沿棱向前爬行，每走一条棱称为“走完一段”.白蚁爬行的路线是$A{A}_1\to A_1{D}_1\to \cdots$黑蚁爬行的路线是$AB\to B{B}_1\to \cdots$它们都遵循如下规则：所爬行的第$i+2$段所在直线与第$i$段所在直线必须是异面直线（其中$i\in N*$）.设黑白二蚁走完第2014段后，各停止在正方体的某个顶点处，这时黑白蚁的距离是   (     )
 

这说明（  ）

    If you are studying at school, do be a polite and clever student! There is no excuse for not doing your assignments. If you can't come to school, you should call your teacher or your classmate ask about homework. It is your responsibility to find out what homework you have missed. It is not the teacher's job to remind you of the missed assignments.

    You must not be absent on a test day. If you are seriously ill, call and let the teacher know you will not be there for the test. If your teacher allows a make-up test, you should take the test, again within one or two days after you return to class. Serious illness is the only reason for missing a test.

    Be on time! It is impolite to be late. Also, it bothers other students. If you must come in late, be sure to do it quietly. Have your books and papers out of your bag before you come into the classroom. Then go to your seat and sit down quietly. In the USA, it is not necessary to knock before you enter the classroom. Most teachers will give you a low grade if you are often late.

    In America, you should call your teacher by his or her last name instead of “teacher”. Also you should use Mr, Miss, Ms or Mrs before the last name (such as Mrs Smith or Mr Jones). The teacher will tell you the title that he or she likes. It is impolite in the USA to eat, drink or chew gum during class. Don't do these until the break. Also, removing your shoes in the classroom is not polite.
