     Helen Keller was a very bright and beautiful girl. At age of six months she could already say a few

words. But before she was two years old, she was badly ill. She could not see or hear, and could not

even talk.

     When she was six, her parents invited a teacher for her. With the help of the teacher, she began to

see and hear the world around her through her hands. She learned to read the books for the blind. The

teacher took Helen for long walks, and told her about all the beautiful sights. Helen touched flowers,

climbed trees, and smelt a storm before it came. She also learned how to swim and ride a horse.

"The Story of My Life". Her story has brought new hope to many blind and deaf people. It gave light to

探究题

近日,学校组织一次“走近新词语”活动。请你参加并完成以下任务。

       活动一:写出下列新词语的通常说法。(任选两个)

       另类  菜鸟  迷你  草根  热卖

   _________________________________________________________________________________________

   _________________________________________________________________________________________

       活动二:探究下列材料,写出你的发现。

       材料1:爷爷一提到“粮票”“烟票”“人民公社”就感慨不已。对他的孙女说,这些词语太陌生了,她经常说的是“上网”“粉丝”“低碳”等新词语。

       材料2:某个娱乐节目搞“海选”,不久到处都“海选”;电视台刚播《蜗居》,老百姓全在说“蜗居”。这些名称一出现,就成了各大媒体报道中的热闹词汇。

       材料3:李老师在批改随笔时,看到了天书般的一段话:“偶灰常稀饭周杰伦,那天偶拿他的片片到班里亮骚,被老斑发现收了去,真是7456……”李老师当场“晕倒”。

       探究发现:____________________________________________________________________________

   ________________________________________________________________________________________

       活动三:下面是老师与学生的一段对话,请在横线处补写恰当的内容。

       学生:老师,《现代汉语词典》怎么把“包装”“下课”作为新词语了?

       老师:因为这些词语在发展过程中,增加了新的意义和用法。举例说,“下课”,原指上课结束,现在又有了被解职的意思。如,某男篮主教练执教不力而下课。

       学生:哦,我明白了!

       老师:那你能不能参照老师的说法,从“包装”“充电”“山寨”三个词语中选择一个来说明这种情况呢?

       学生:________________________________________________________________________________

       老师:这个例子举得好,看来你是真的明白了。
