Experts have put forward detailed plans for a tunnel to join Taiwan with the Chinese mainland．
The shortest proposed route would be 126 kilometers―more than twice the length of the English Channel Tunnel．And the longest proposed route would be 207 kilometers．
A recent conference in xiamen，Fujian Province brought together more than 70 experts．The event was co一sponsored(共同发起)by universities from Taiwan and the Chinese mainland．Fujian is the province where both proposed mutes would begin．
There is no direct passenger access(通道)between the mainland and Taiwan by air or sea at the moment．
Experts say that it is better to start research sooner rather than later，although there is a lack of government funding(资金)．There are no technical problems t0 build a Taiwan tunnel．But it will require an improved political relationship across the Straits．
A professor of TsinghHa University said，“A special feature of huge projects is that the period of preparation is longer than the period of construction．”
For example，he said，the English channel Tunnel took 14 years of planning and had been discussed for two centuries．And preparations for the huge Three Corges(三峡)dam on the Yangze River began in the 1950s．
The xiamen conference focused on the longest southern route，which would use the Taiwan-controlled islands of Jinmen and Penghu as steppingstones.
The first stage of the new project could be a bridge to cross the five kilometers between Xiamen and Jinmen．This would mean that traveling from Xiamen to Jinmen by car would only take five minutes．
The longest tunnel now being planned anywhere in the world is the 54-kilometer land tunnel to link Lyon in France with Turin in Italy．The tunnel will not be completed until 2015-2020．
48．Which is the longest tunnel in the world at present?
A．The English Channel Tunnel．
B．The tunnel between Lyon and Turin．
C．The
D．The passage doesn’t mention it．
49．The example of English Channel Tunnel shows――．
A．it’s important to complete a huge project
B．there are many problems to be solved before doing something
C．discussions among countries usually take a lot of time
D．the preparation takes 1onger time than the construction
50．Which of the following is NOT true?
A．Universities both at home and abroad have sponsored(赞助)the plan．
B. If the project is completed，the world's longest tunnel will appear． ．
C．You can't reach
D．The starting point of the proposed tunnel is in Fujian．
51．What is the possible difficulty in carrying out the plan?
A．The 1ack of money for the project from the government．
B．Improving the relationship between Taiwan and the mainland．
C．The detailed plans for the tunnel．
D．The technical problems with the tunnel．
48．D
解析：题目的意思是指现在世界上最长的已经建成的隧道。英吉利海峡隧道并没有在文章中提到是否是最长的；根据文章的最后一段，法国到意大利的海峡隧道还未建成；台湾海峡隧道虽是文章介绍的主题，但还在计划之中，所以文章没有告诉我们答案。
49．D
解析：英吉利海峡隧道的例子在第八段，主要是为了证明第七段的观点。
50．A
解析：文章只提到计划是台湾和大陆的大学发起，没有提到国外的大学，故A项不对；B项不能只看文章最后一段提到法国至意大利的海峡隧道是最长的，而the project(台湾海峡隧道)比它要长的多；c项在第五段提到；D项在第四段提到。
51．B
解析：从第六段的But it will require and improved political relationship across the Straits．中"require(需要)”，说明这方面还是障碍；虽然第六段中提到A项，但句中用了although(尽管)这个词，可见资金方面不是主要问题；c项是文章一开始就说明已经完成的事项；D项从第六段There are no technical problems to build a Taiwan tunnel．得知，也是不成问题的。
