参考答案和解析
正确答案： C,A
解析： Java的移位操作符一共有三种，分别是”>>”,”>>>”,”<<”,执行的操作分别是有符号右移，无符号右移，左移，有符号右移的意思是说移入的最高位和原最高符号位相同，无符号右移是移入位始终补零，左移时最低位始终补零，最高位被舍弃。移位操作符另一个非常值得注意的特点是其右操作数是取模运算的，意思是说对于一个int型数据而言，对它移位32位的结果是保持不变而非变成零，即：a>>32的结果是a而不是0，同理，对long型数是对右操作数取64的模，a>>64==a；还有一点需要注意的是移位操作符”>>>”只对int型和long型有效，对byte或者short的操作将导致自动类型转换，而且是带符号的。

    答案：B
    解析：
    考查课堂教学中的教师指令语。教师的课堂指令语应简洁明了，这样学生才会明白；切忌长而复杂．这样不便于学生理解，也会影响教学的效率。教师在课堂上应尽量少用母语，必要时可以使用身体语言辅助学生理解。课堂指令语不应过多，教师应最大限度地发挥学生的主观能动性。故选B。

    正确答案： A
    解析：
    细节归纳题。文章第一段第三句提到，就像你有权发表你的意见一样，我也有权发表我的意见。末段指出，是不是每个人都被赋予发表意见的权利？那当然。每个人都有发表个人意见的权利，这是中心内容。故A项“人人都有权拥有自己的意见”符合文章内容。文章首段第三句提到，若不太重视意见时，随意使用他不会引起乱子。可见，B项“自由发表意见常引起混乱”与原文不符。文章开头提到，对“意见”一词的使用分成三类：品位，信念和判断。对第一种的使用有些粗心，后两种不是，所以，C项“在构成意见上，大多数人往往是粗心的”与原文不符。文中仅在讲到品位时说明滥用意见一词会引起无聊的争吵，其他使用意见时没有D项“随便使用‘意见’一词，常引起吵架”意思。综上所述，A项正确。
