Not all the students obey the rules. Which of the following statement has the same meaning as it.
A．None of the students obey the rules.
B．All the students don’t obey the rules.
C．No students obey the rules
D．All of the above
答案
答案：B
题目分析：考查部分否定句。All, both,与not连用表示部分否定，不管not在前面还是在后面。句意：不是所有的学生都遵守规则，故B正确。AC是全部否定指所有的学生都不遵守规则。
点评：部分否定句的考查要注意not的位置问题，不管not的位置在前在后都表达一样的意思。
