11.Animals Can Sense Natural Disasters
Among the dead in South Asia's tsunami(海嘯)were many tourists at Sri Lanka's national wildlife park at Yala.But very few of the park's animals-elephants,buffaloes,monkeys and wild cats-appear to have died.There are theories that animals can sense natural disasters and run away to safety.
First,it's possible that the animals may have heard the quake before the tsunami hit.The underwater burst produced sound waves known as infrasound(次聲).Humans can't hear infrasound,but many animals including dogs,elephants,tigers and pigeons can.
A second early warning sign the animals might have sensed is ground vibration(震動).The great quake would have produced vibrational waves known as Rayleigh waves.These vibrations move through the ground like waves moving on the surface of the ocean but faster.They travel at ten times the speed of sound.The Rayleigh waves would have reached Sri Lanka hours before the water hit.Mammals,birds,insects and spiders can sense Rayleigh waves.So the animals at Yala might have felt the Rayleigh waves and then run to higher ground.
But what about humans?While we can't hear infrasound,we can feel it,although we don't necessarily know we're feeling it.We also experience Rayleigh waves by special sensors in our joints(關節(jié)),which exist just for that purpose.Sadly,it seems we don't pay attention to the information when we get it.Maybe we screen it out because there's so much going on before our eyes and in our ears.

56.Why did few animals at Yala die when the tsunamis that caused a huge number of human deaths hit?D
A.Because human beings cannot hear the infrasonic sound.
B.Because the animals were staying at a higher place in the park.
C.Because the animals were able to run much faster than human beings.
D.Because the animals might have picked up the danger signals and ran away.
57.Which of the statements about"Rayleigh waves"is true?A
A.Rayleigh waves can be felt both by animals and human beings.
B.Rayleigh waves,just like infrasonic sound,can only be felt by animals.
C.Rayleigh waves are vibrational waves that usually cause quakes or tsunamis.
D.Rayleigh waves move on the ocean surface at a speed ten times that of sound waves.
58.According to the passage,which of the statement is true?B
A.We can't feel the infrasound so we can't be informed of the danger.
B.We ignore the information of tsunami's coming even though we can also get it.
C.We were so busy on our minds that we feel neither infrasound nor Rayleigh waves.
D.We can feel Rayleigh waves and infrasound so we can escape the danger like animals.

分析 本文分析了動物為什么可以逃開自然災害?尤其分析了在這次的海嘯中很多的短文逃生的原因.

解答 56.D 細節(jié)題.根據(jù)第一段最后一句There are theories that animals can sense natural disasters and run away to safety.說明動物似乎已經(jīng)能夠感覺到危險,會早點逃開.D正確.
57.A 細節(jié)題.根據(jù)文章3,4段We also experience Rayleigh waves by special sensors in our joints(關節(jié)),which exist just for that purpose.和Mammals,birds,insects and spiders can sense Rayleigh waves.說明動物和人都可以感覺到Rayleigh waves.故A正確.
58.B 細節(jié)題.根據(jù)文章倒數(shù)第二行it seems we don't pay attention to the information when we get it.可知我們往往會忽略我們得到的信息,說明B正確.

點評 閱讀理解題測試考生在閱讀基礎上的邏輯推理能力,要求考生根據(jù)文章所述事件的邏輯關系,對未說明的趨勢或結(jié)局作出合理的推斷;或根據(jù)作者所闡述的觀點理論,對文章未涉及的現(xiàn)象、事例給以解釋.考生首先要仔細閱讀短文,完整了解信息,準確把握作者觀點.

Investing(投資) In Bulls,Woman Begins To Escape From Poverty
In Shahinoor's household there were days when she struggled to put even one meal on the family table.She and her husband are among Bangladesh's poorest:those with no land,no wealth and little hope of breaking out of hunger and poverty.But a new programme to unlock the entrepreneurial(創(chuàng)業(yè)的) spirit of Bangladeshi women has transformed her life.

2.Two new electronic book products (the SoftBook and the PocketBook) have gathered extensive press coverage,including articles in ABC News,the New York Times,San Jose Mercury News,and WIRED.
An electronic book (e-book) is a book-length publication in digital form,consisting of text,images,or both,and produced on,published through,and readable on computers or other electronic devices.Different from a traditional printed book,e-books are born digital.
Being a firm believer in tablet computers for many tasks not involving heavy data entry,I applaud these new designs of the products.In particular,the SoftBook has nice leather binding (封皮),going far beyond the traditional (and boring) industrial design used for other portable computers.The PocketBook has a more traditional industrial design,typical of leading electronic gadgets (小配件).
Unfortunately,neither company mentions their product's screen resolution (分辨率).Low-resolution monitors (including all computer screens until now) have poor readability:people read about 25% slower from computer screens than from printed paper.Scientists believe that only the screen with 300dpi displays has the same reading speed as print.So unless they have much better screens,electronic books will have a problem.
A project called"the last book"is getting much attention,which aims at producing a computer in the form of a folio (對開本):a set of pages using"digital ink".Users would move forward in the information by turning pages just as they do in a printed book.Hopefully,the scientists will eventually invent a way to make the"digital ink"display characters at a high enough resolution to gain the same reading speed as print.
Even when e-books gain the same reading speed as print,they will still be a bad idea.Page turning remains a bad interface (界面),even when it can be done more conveniently than by clicking the mouse on a"next page"button.
Another problem is that most e-book publishers do not warn their customers about the real meaning of the digital rights management (DRM) tied to their products.Generally they claim that it is meant to prevent copying of the e-book.However,in many cases it is also possible that it will result in the complete denial of access by the purchaser to the e-book.The e-book is tied to a specific computer or device.In these cases,the DRM will usually let the purchaser move the book a limited number of times after which they cannot use it on any additional devices.If the purchaser upgrades or replaces their devices,they may lose access to their purchase.Some forms of the DRM depend on the existence of online services to authenticate (認證) the purchasers.When the company that provides the service goes out of business or decides to stop providing the service,the purchaser will no longer be able to access the e-book.

67.From the underlined sentence in Paragraph 3,we know that the writerB.
A.has bought the two new products before
B.likes the special designs of the new products
C.thinks it more convenient to use traditional computers
D.doesn't like the traditional design of portable computers
68.We can learn from the passage thatD.
A.born digital,e-books can only be read on computers
B."digital ink"has gained the same reading speed as print
C.now all the computers are using the screens with 300dpi displays
D.e-books may have slower reading speed compared with printed books
69.Due to the digital rights management,C.
A.the e-book should be tied to a specific device
B.people should upgrade their devices regularly
C.readers are likely to lose access to their purchase
D.only purchasers can download the book without limit
70.This passage mainly talks aboutA.
A.the disadvantages of electronic books   B.the future of electronic books
C.the designs of electronic books         D.two new electronic books.

19.NEW YORK (Reuters)-The average number of monthly visitors to U.S.newspaper websites rose by nearly a third in the first half of 2006,a study released on Wednesday said,though print readership at some larger papers fell.
The study,released by the Newspaper Association of America,underlines the internet's importance to papers beset (圍困)by failing circulation and advertising income in their print editions.
The average number of unique visitors to online newspaper sites in the first half was more than 55.5 million a month,the study said.That compares with 42.2 million a year earlier."Newspaper websites have become a significant addition to the print product,and are driving large audience growth,"said John Kimball9 the association's chief marketing officer.The number of page views at newspaper sites rose by about 52 percent in the first half,the association added.
US Newspaper publishers have been fighting to hold on to advertisers as many of them lose readers to other media,including the Internet.
Key to the latest report is the finding that websites are bringing in more younger readers,the association said.
The Washington Post,s website increased its audience reach among readers aged 25 to 34 by more than 60 percent,the report said.Audience reach^combines the average weekly print audience and the net 30-day website audience.
Overall,newspaper websites helped drive a 15 percent increase in the total newspaper audience for 25-to-34-year olds and a 10-percent increase for 18-to 24-year olds,the association said.
It did not provide comparisons to the same period last year for total print newspaper readership.Readership numbers,which were provided by Scarborough Research,include circulation,shared copies and any other way that someone could end up reading a newspaper.
Print readership fell,according to a comparison of figures from the two periods conducted by Renter,.‘
The New York Times readership dropped 5.8 percent,while the largest U.S.paper,USA Today,fell 3 percent.The Wall Street Journal saw readership remain nearly the same.
39.Which would be the best title for the passage?A
A.Online Newspaper Readership Grows
B.Convenient Way to Read Newspapers
C.rThe Internet Is Taking over in the World
D.Print Newspapers Have Lost Their Advantages
40.Why have US Newspaper publishers been fighting?C

16.Three years ago,I met a little girl named Alicia.She had brown hair and big,green eyes.She looked like a normal 7-year-old girl.She had autism(自閉癥),but that didn't mean she wasn't bright.In fact,one day proved just that.
As I walked into the room to meet with Alicia,I noticed that she was sitting in the corner alone."Hey there Alicia!What are you doing?"She immediately looked down.I was used to this."Thinking."She said."About what?""Butterflies.""What about them?"Then,she looked me right in the eye and said"Today I was outside looking at flowers,and I saw a butterfly.I began chasing it and finally caught it.I took it inside to show the nurse and she said,‘Oh,honey,you have to let it go.'I didn't want to let it go.I was so happy I had a new friend,but the nurse said that if I didn't let it go,it would die.I didn't want it to die so I ran outside and let it go.I was so happy."
