写作。

     假如你叫李华,是一名正在澳大利亚某中学交流的学生,在当地报纸上读到以下报道中

国高考的文章:

    Gaokao, China's college entry test, is considered to be the most difficult academic test in the world.

Only a lucky few are able to cross the "single-log bridge", standing out from thousands of candidates.

It is gaokao that largely determines Chinese students' future success.

    你不太赞同这种理解。请你用英语给该报编辑写一封信,谈一谈不上大学也有自己的

优势,亦可有所作为。

注意:

     ①无须写标题,不得照抄英语提示语;

     ②除诗歌外,文体不限;

     ③开头和结尾已给出,不得再抄写,不计入总词数;

     ④文中不得透露个人姓名和学校名称;

     ⑤词数为120左右。

     Dear Sir or Madam,

            I appreciate your interest in China' gaokao. However, as a young man from China, I'm afraid

     I don't quite agree with the definition given.
