     These days, it is easier for us to travel to other countries than ever before. However, there is a big
difficulty that most of us    1   when we meet people in other countries, we cannot communicate with
them. There are    2   where English is still not spoken, though it is the most widely known language. So,
wouldn't it be _ 3_ if there was one language that could be understood by anyone anywhere in the world?
Esperanto that was created in 1887 may be the world's   4    truly international language. In fact, although 
  5    artificial (人造的) languages have been already created, only Esperanto has had much success. Its
learners say that it is about four times    6   to learn than other languages. Spelling and pronunciation are
both easy, too. For example, it does not have silent   7    like the "h" in" honest". If you    8   a word, you
can spell it without any difficulty. The grammar is also as simple as possible: only sixteen basic    9  , no
irregular verbs (不规则动词), only six verb endings.
     In short, Esperanto should be attractive (有吸引力的) as a language to learn,    10   there is a
problem: how many people have met anyone who can really speak it? Anyway, we hope that some day
one language can be mastered easily by anyone.

阅读理解与欣赏

阅读《三峡》与《答谢中书书》,。(1 5分)

自三峡七百里中,两岸连山,略无阙处。重岩叠嶂,隐天蔽日,自非亭午夜分不见曦月。至于夏水襄陵,沿溯阻绝。或王命急宣,有时朝发白帝,暮到江陵,其间千二百里.虽乘奔御风不以疾也。春冬之时,则素湍绿潭,回清倒影。绝巘生怪柏,悬泉瀑布,飞漱其间。清荣峻芨.良多趣味。

每至晴初霜旦,林寒涧肃,常有高猿长啸,属引凄异,空谷传响,哀转久绝。故渔者歌日:“巴东三峡巫峡长,猿呜三声泪沾裳!”。

山川之美,古来共谈。高峰入云,清流见底。两岸石壁,五色交辉;青林翠竹,四时俱备。晓雾将歇,猿乌乱呜;夕日欲颓,沉鳞竞跃。实是欲界之仙都,自康乐以来,未复有能与其奇者。《答谢中书书》
