宪法是国家的根本大法，具有最高法律效力。下列有关宪法法律效力的表述中，正确的是( )。
A．在不成文宪法的国家中，宪法的法律效力高于其他法律
B．在我国，任何法律法规都不得与宪法规范、宪法基本原则和宪法精神相抵触
C．宪法的法律效力主要表现为对公民的行为约束
D．宪法的法律效力不具有任何强制性
参考答案：B
解析： 在不成文宪法国家，没有统一的宪法典，没有根本法意义上的宪法，只存在部门法意义上的宪法(一般包括宪法性法律、宪法性惯例、宪法性判例、国际条约和国际习惯)；其宪法性法律与其他法律的效力完全相同。宪法的核心价值取向在于限制国家权力以保障 * * ，因此宪法的法律效力主要表现于对国家机关的行为约束。

| "You are my best friend." It’s the nicest thing you can 1 to someone. It’s also the nicest thing you  can 2 someone. Good friendships begin in middle school. It’s the 3 you begin to develop your own personality. Your parents aren’t around so you 4 lots of time every day sharing your life with your classmates. You talk with them, you work with them and you become friends with them. But 5 them will become your “best” friend. Best friends are the people who like you and 6 you the most. They are the 7 who are easy to work with and easy to have fun with. Sometimes it’s 8 to find a best friend. And sometimes you can 9 a little lonely. But just because you don’t have best friend now, it doesn’t mean you 10 one in the future. Best friends seem to find each other as if by magic. And when you find your best friend, the magic will last forever. | |||
