阅读理解
    In a class this past December, after I wrote some directions on the board for students about their final examination, one young woman quickly took a picture of the board using her smart phone. When I looked in her direction, she apologized, “Sorry. Was it wrong to take a picture?”
    “I can't read my own handwriting,” the young woman explained. “It's best if I take a picture of your writing so I can understand the notes.”
    That remark started a class-wide discussion about taking a picture instead of taking notes. For those in the photo-taking camp, reasons extended(扩展) beyond their inability to comprehend their own handwriting. Some took pictures of notes because they knew their phone was a safe place to store material. They might lose paper, but they wouldn't lose their phones. Some took photos because they wanted to record exactly the way in which I had noted information on the board. Others told me that during class they liked to be able to listen to the discussion attentively.
    Yet the use of cameras may be convenient, it does raise questions for the classroom. Is a picture an effective replacement for the process of note-taking?
    Teachers encourage students to take notes because the act of doing so is more than just recording necessary information—it helps prepare the way for understanding. Encouraging students to take notes may be an old-fashioned method, but just because a method has a long history doesn't mean it's out of date. Writing things down engages a student's brain in listening, visual, and kinesthetic(触觉的) learning. The act of writing down information enables a person to begin to memorize, to process and combine it, helping learning new knowledge.
    Taking a picture does indeed record the information, but it lacks some of the necessary mental activities that taking notes employs. So can the two be equally effective?

阅读下面文章,完成下列各题。

被放逐的皇后

金建云

      ①我爸去世后,我妈越活越不招人待见。

      ②她用iPad打发孙子,烧饭忽咸忽淡,记账乱七八糟,将自己锁在门外,时不时将孙子忘在幼儿园……谁敢相信,妈妈退休前曾是高中的特级教师呢?我教她玩微信,陪她旅游,帮她买健身器材,带她找老玩伴,催她跳广场舞……却是无法让她找回青春时代的光彩与热情,她永远是热闹场合的陌生人。

      ③对老妈这种状态,我实在无法理解,直到有一日,我发现她在读一本书:阿尔诺•盖格尔的《流放的老国王》。这么伤感的书,怪不得她越看情绪越低落!为了批判这一株“精神毒草”,我偷偷读起来。

      ④作者描写了自己父亲老去的过程,将患帕金森症的父亲比喻为一位被流放的国王,原本熟悉的家庭环境对父亲来说,已变得越来越陌生,他仿佛身处异乡。这位父亲一心要回到自己记忆中的家,于是“不知所措地四处乱窜”。作者看到父亲慢慢“变傻”,仿佛感到生命从他身上渗出,整个人的个性一滴滴漏掉……

      ⑤读到感人之处,我黯然神伤!这么久以来,我没有真正理解父亲去世对老妈的打击。我只是一味地怪她不乐观、不振作,却从未从她的角度看待过她内心的挣扎与无奈。大致浏览完这本书,我走出我妈的卧室,她正在客厅看电视。

      ⑥像往常一样,她看电视的眼神中散发着淡漠的霉味。屏幕上演的什么对她来说毫无意义,她需要足够响的声音来冲淡自己的寂寞。

      ⑦我坐下来,同她聊起电视上的这位笑星。她支支吾吾应对着我,敷衍着笑几声。看得出,她对我今天“反常”的表现感到一丝惶恐。自从父亲走后,她变得越来越像个爱犯错的刁蛮女孩,对我,竞有一种说不出的紧张感。或许是怕我唠叨她吧,她借口说自己要烧饭,就把我独自撂在沙发上。

      ⑧厨房里她的动作好慢,时常停下来若有所思,又不知道在思考什么。她拿起盐瓶,思考自己究竟有没有放盐,停顿几秒钟后,她放了一点点,再加上一点点……

      ⑨这时候,我想起过世的父亲。父亲生前总会在她烧饭的时候,凑过去聊天。那时候,我妈嘴上对答如流,手上有条不紊。她永远井井有条、遇事不慌,谈笑之间便将美味端上餐桌。

      ⑩如今,一个走了,一个活在女儿的嗔怪与脸色之中。

      ⑪看着我妈的背影,我感到岁月流逝的巨大冲击力——不知不觉中,母亲已经走入孤单的晚年,她仿佛一位被流放的皇后,手足无措地面对这个对她来说越来越陌生的世界。爱她的父母、丈夫、老朋友们,逐一离去,唯一的女儿整天抱怨她不乐观、不阳光、不振作……米兰•昆德拉的一句话浮现在我脑海中——“面对生命那无可挽回的溃败,我们唯一能做的事情就是理解它。”

      ⑫如果说,衰老与孤独是我妈必须面对的生命之溃败,那么,我不该再要求她强颜欢笑,不该带她去那些她完全无法融入的热闹环境中,更不应该责怪她带孩子、做家务不走心——如果她的心都不知道何处安放,又怎么谈得上走心不走心呢?

      ⑬我走进厨房,默默地打开她忘记打开的抽油烟机。我给她嘴里塞进一块糖,微笑着看她笨手笨脚地做事。厨房里很安静,抽烟机的声音竞带给我们默契的温暖感。我妈朝我笑笑,我也朝她笑笑。那种很幸福的感觉涌上心头。

      ⑭是的,当我放弃对她所有的要求之后,那种叫作“理解”的东西,如圣灵一般翩然而至。

      ⑮“妈妈,愿我的理解能安放你的孤独。”我在心里默默地说。
