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。

When scientists set out to explore the roots of human laughter, some apes（类人猿） were just tickled（胳肢）to help. That’s how researchers made a variety of apes and some human babies laugh. After analyzing the sounds, they concluded that people and great apes inherited laughter from a shared ancestor that lived more than 10 million years ago. Experts praised the work, it gives strong evidence that ape laughter and human laughter are related through evolution（进化）.
Scientists have noted that apes make characteristic sounds during play or while being tickled, especially to signal that they’re interested in playing. It’s been suggested before that human laughter grew out of primate（灵长类动物） roots. But ape laughter doesn’t sound like human laughter. It may be slower noisy breathing. So what does that have to do with the human ha-ha? To investigate that, Marina Davila Ross and her colleagues carried out a detailed analysis of the sounds made by tickling three human babies and 21 other primates, apes included.
After measuring 11 features in the sound from each species, they tried to find out how these sounds appeared to be related to each other. The result looked like a family tree. Significantly, that tree matched the way the species themselves are related, the scientists reported online in the journal Current Biology. They also concluded that while human laughter sounds much different from ape laughter, their typical features could have come from the same ancestor.
Panksepp, who studies laughter-like responses in animals but didn’t participate in the new work, called the paper exciting. Panksepp’s own work concludes that even rats produce laughter in response to playing and tickling, with sounds that can hardly be heard by people. Robert Provine, a scientist, who wrote the book, Laughter: A Scientific Investigation, said the new paper showed some important clues, like ape sounds that hadn’t been realized before.
69. Why did the scientists analyze the laughter made by tickling human babies and apes?
A. To try to discover if they can make characteristic sounds.
B. To see if they interested in playing.
C. To find out if the laughter of apes and humans is related.
D. To find out the differences between humans and apes.
70. Based on Paragraph 3 we can know that researchers measured the features in the sound to ________.
A. find out ape sounds that hadn’t been realized before
B. find out relations among primates’ laughter
C. see what a family tree from each species looks like
D. make a report online in the journal Current Biology
71. What can be inferred from the last paragraph?
A. Panksepp spoke highly of the new research.
B. Rat laughter is likely to be related to ape laughter.
C. Robert Provine provided some new clues for the researchers.
D. Humans don’t enjoy listening to ape laughter.
72. What would be the best title for the passage?
A. Ape study explores evolution of laughter.
B. Apes like to laugh when being tickled.
C. Human laughter and ape laughter are different.
D. Laughter: A Scientific Investigation.
