Answer 1

分析 本文是开放性作文，根据所给提示信息，针对这一现象发表看法，以此为话题进行思维和联想，自由发挥写一封建议信，又属于提纲作文．
在写作时以第一人称和第二人称为主，时态以一般现在时为主．
重要短语：bring sb convenience（给某人带来便捷），would like to do sth（想要做某事），stare at（盯着看），miss the chance（错过机会），surf the Internet（上网），cross the street（穿过街），care about（关心），as far as I am concerned（就我所关注的而言），do harm to（对…有害），hold up（举起）．
【高分句型一】
1．However，more and more phubbers，especially young people，would like to stare at their screen，①surfing or playing games，②no matter whether they are on a bus or a train，and no matter how far the journey is．
①此处是由两个现在分词短语"surfing or playing games"作伴随状语，主句为"young people，would like to stare at their screen"，主句的主语"young people"．
②此处是由"no matter+疑问词"引导的让步状语从句．
【高分句型二】
2．And even they will not miss the chance to surf the in internet when crossing the street．
  此处是时间状语从句中的省略"连词when+现在分词"，可以理解为"when they cross the street"．
3．They never care about what happened around．
  此处是由疑问代词"what"引导的宾语从句．
【高分句型四】
4．As far as I am concerned，phubbing on a moving bus does harm to their eyes．
此处是由动名词短语"phubbing on a moving bus"作主语，谓语动词为"does harm to"，宾语为"their eyes"，动名词作主语谓语动词用单数．

解答 The mobile phone has been part of our life．Mobile phones bring us much convenience．However，more and more phubbers，especially young people，would like to stare at their screen，surfing or playing games，no matter whether they are on a bus or a train，and no matter how far the journey is．【高分句型一】And even they will not miss the chance to surf the in internet when crossing the street．【高分句型二】They never care about what happened around．【高分句型三】（结合自身实际提出应采取的积极态度和应对方法） 
 As far as I am concerned，phubbing on a moving bus does harm to their eyes．【高分句型四】Besides，phubbing is also dangerous while crossing the street．Wish phubbers hold up their heads to enjoy surroundings．（看法）

点评 开放性作文给出一定的写作主题，并此为基础进行思维和联想，自由发挥．不仅考查学生在内容、结构安排、语言运用和组织方面的能力，而且对学生的想像力、发散思维、归纳判断能力也有很高的要求．写好这类作文要注意几个步骤：1． 认真审题，找准提示语中的关键词或句，确定中心思想．2． 依据关键句，草拟提纲，梳理文章的脉络3． 准确定位人称、时态．注意使用高级词汇和高级句型使文章显得更有档次．4．最后还要认真查验是否有漏写情况，有无拼写错误及标点误用等．
