5.It's often said that the eye is the window to the soul.But in this case,the eye is the window to Windows.At least,that was the goal when EyeTech Digital Systems got the help of some BYU engineering students in creating an all-in-one eye-tracking system.
The idea behind the project was to create an inexpensive computer system that could be controlled completely with a person's eyes.The hope was that this system could be used by people  with disabilities in parts of the world where they can't afford expensive eye-tracking systems.The students created the tablet(书写板)for their yearlong engineering project for their customer,EyeTech Digital Systems,an Arizona-based company that designs and develops eye-tracking software.
A separate BYU engineering team also worked with EyeTech last year to develop and improve the initial eye-tracking tephnology,but this year's focus was to put the eye tracking into a housing similar to a thick PC.The finished product runs Windows 7 and has the eye-tracking system built in.After a quick adjustment,the system can move the mouse to wherever the user is currently looking.All it takes is a blink(眨眼)to click.
Systems with similar abilities can cost upwards of 14,000.Butthestudentswereabletofindcheaper,readilyavailableparts,pushingthecostdowntounder1,500.Jedediah Nieveen,the captain for this year's team,said the project was a challenge,but one that was rewarding on many levels."A lot of times in school you just work problems out of books,"he said."But this allowed us to take what we learned and apply it to something in real life,something that can help a lot of people,and that's really helped me."
Although the primary purpose of the product is to help people with disabilities,the technology could also have broader applications in the fields of research,advertising and even gaming.
71.According to the text,the eye-tracking system isB   
A.a high-tech computer                                    
B.a computer system operated by eyes
C.a way of protecting eyes                                
D.a software against information theft
72.How long will the research of the eye-tracking project last in all?A
A.About two years.                   
B.Just one year.
C.Over three years.                  
D.Less than one year.
73.The eye-tracking system was created toC   
A.help the poor students                                  
B.improve the computer system
C.support the disabled people                             
D.help to cure people's disabilities
74.What did the BYU engineering students value most during the project?B
A.Earning money for their education.
B.Putting their theory into practice.
C.Showing their talents in technology.
D.Increasing their job opportunities.
75.What can be inferred about the future of the eye-tracking system?A

11.When asked about happiness,we usually think of something extraordinary,an absolute delight,which seems to get rarer as we get older.
For kids,happiness has a magical quality.Their delight at winning a race or getting a new bike is unreserved(毫不掩饰的).
In the teenage years,the concept of happiness changes.Suddenly It's conditional on such things as excitement,love and popularity.I can still recall the excitement of being invited to dance with the most attractive boy at the school party.
In adulthood the things that bring deep joy-love,marriage,birth-also bring responsibility and the risk of loss.For adults,happiness is complex.
My definition of happiness is"the capacity for enjoyment".The more we can enjoy what we have,the happier we are.It's easy to overlook(忽视) the pleasure we get from the company of friends,the freedom to live where we please,and even good health.
I experienced my little moments of pleasure yesterday.First I was overjoyed when I shut the last lunch-box and had the house to myself.Then I spent an uninterrupted morning writing,which I love.When the kids and my husband came home,I enjoyed their noise after the quiet of the day.
Psychologists tell us that to be happy we need a mix of enjoyable leisure time and satisfying work.I don't think that my grandmother,who raised 14children,had much of either.She did have a network of close friends and family,and maybe this is what satisfied her most.
We,however,with so many choices and such pressure to succeed in every area,have turned happiness into one more thing we've got to have.We've so self-conscious about our"right"to it that it's making us miserable.So we chase it and equal it with wealth and success,without noticing that the people who have those things aren't necessarily happier.
Happiness isn't about what happens to us-it's about how we see what happens to us.It's the skillful way of finding a positive for every negative.It's not wishing for what we don't have,but enjoying what we do possess.
29.As people grow older,theyB.
A.care less about their happiness   
B.feel it harder to experience happiness
C.will take fewer risks in pursuing happiness       
D.tend to believe responsibility means happiness
30.What can we learn about the author from Paragraph 5and 6?D
A.She cares little about her own health
B.She enjoys the freedom of traveling
C.She prefers getting pleasure from loneliness       
D.She is easily pleased by things in daily life
31.People who equal happiness with wealth and successA.
A.stress their right to happiness too much    
B.consider pressure something blocking their way
C.are at a loss to make correct choices   
D.are more likely to be happy
32.What can be concluded from the passage?C
A.Happiness lies in wealth
B.Each man is the servant of his own life
C.Happy is he who is content
D.Success leads to Happiness.

10.We have seen that pesticides(杀虫剂) now pollute soil,water and food,and that they have the power to make our rivers fishless and our gardens and woodlands silent and birdless.Man,however much he may like to pretend the opposite,is part of nature.Can he escape a pollution that is now so thoroughly spread throughout our world?
We know that even single exposure to these chemicals,if the amount is large enough,can cause extremely severe poisoning.But this is not the major problem.The sudden illness or death of farmers,farm workers and others exposed to enough quantities of pesticides is very sad and should not happen.For the population as a whole,we must pay more attention to the delayed effects of taking in small amounts of the pesticides that unseeably pollute our world.
Responsible public health officials have pointed out that the biological effects of chemicals are increasing in amount over long periods of time,and that the danger to the man may depend on the amount of the exposures received throughout his lifetime.For these very reasons people easily take no notice of the danger.It is human nature to shake off what may seem to us a future disaster."Men are naturally most impressed by diseases which have obvious signs,"says a wise physician,Dr.Rene Dubos,"yet some of their worst enemies slowly come near them unnoticed."

62.Which of the following can best summarize the first paragraph of this passage?_C
A.Man has a responsibility to bear for what has happened to nature.
B.Possibly man will escape the effects of environmental pollution.
C.Pesticide-caused pollution may also kill people.
D.Man acts as if he did not belong to nature.
63.People do not give enough attention to the delayed effects of exposure to chemicals becauseD.
A.imited exposure to them does little harm to people's health
B.the present is more important to them than the future
C.humans are able to bear small amounts of poisoning
D.the danger does not become seen clearly and immediately
64.Which of the following statements is true according to the passage?_A
A.A person exposed to pesticides even once may get seriously poisoned.
B.Birds are less sensitive to pesticides than humans.
C.The effects of pesticides on humans do not last as long as on fish.
D.Taking in small amounts of pesticides will not cause serious results.
65.We can conclude from what Dr Dubos says thatB.
A.people usually find hidden diseases difficult to deal with
B.people fail to notice hidden dangers caused by pesticides
C.diseases with obvious signs are mostly easy to cure
D.attacks by hidden enemies are likely to be deadly.

17.Running like the wind,roaring like thunder,tigers have long been feared and respected as a king of the animal world.But last week a report said that there are no more than 30wild tigers left in south China.
This was the conclusion of a team of scientists from China's State Forestry Administration and the World Nature Fund.
The South China tiger,also known as the Chinese tiger,is native to southern China.In the 1950's,there were over 4000tigers found in mountain forests in the country.But due to the destruction of their natural habitat and uncontrolled hunting,it has been pushed on to the list of the world's top ten most endangered species.
Sixty-six of the big cats can be found in the cages of a dozen zoos around China.But they are nothing like their wild cousins.They have lost their natural skills such as hunting and killing.If they were set free they could not look after themselves.
"Breeding has damaged the quality of the species",said Pei Enle,deputy director of the Shanghai Zoo.
To reintroduce the species into the wild,the country started a programme to send five to ten young tigers to South Africa.Four of them have already arrived.Progress has been made as two elder tigers have recovered some of their instincts(本能)and can hunt wild animals by themselves at the African base.
"South Africans are very experienced in reintroducing big animals to the wild.The country has very good natural conditions for the tigers to learn in",said Lu Jun,office director of the National Wildlife Research and Development Center."We tried in Fujian Province,but it was not successful as there was not a complete eco-chain(生物链) and there was a lack of space."
The tigers should return to China in 2007when the reservations in Fujian are ready.

71.What is the main reason for the South China tiger becoming one of the world's top ten most endangered species?D
A.Because it has lost its natural instincts.
B.Because there is not a complete eco-chain.
C.Because there is no space for it.
D.Because uncontrolled hunting has destroyed its natural living conditions.
72.How is the programme of sending several tigers to South Africa getting on?C
A.Its effect still remains to be seen.
B.Two tigers can already compete with their wild cousins.
C.Some of the tigers are already on the road to recovering their natural skills.
D.The tigers should be able to recover their instincts completely by 2007.
73.By saying"but they are nothing like their wild cousins",the writer means thatB.
A.they are no longer feared by other wild animals
B.they don't know how to hunt or kill
C.a complete change has resulted in the species because of breeding
D.to reintroduce them into the wild has become an urgent task
74.What is the purpose of sending young tigers to South Africa?A
A.To help the tigers recover their ability to live in the wild.
B.To provide them with a better environment.
C.To get the tigers to go on a tour.
D.To find a complete eco-chain for them.
75.Which one is not the reason for South Africa being chosen as the training place?A
A.Because the tigers can hunt wild animals by themselves at the African base.
B.Because South Africans are skilled at dealing with the tigers.
C.Because there is a complete eco-chain and enough space there.
D.Because the country has good natural conditions for the tigers to learn in.

14.Japan's nuclear crisis(危机)has caused global alarm and reviews of safety at atomic power plants around the world.
"Japan's nuclear crisis was mainly public panic,not radiation risk",an Australian expert,Michele Kearney,remained cheerful about the future development of international nuclear industry.
Professor Barry Brook,the director of Climate Science at Australian University,said that the crisis will lead international governments to improve measures to protect nuclear plants against extreme natural events,but is unlikely to cut down the use of nuclear power.
"It should be kept in mind that the explosions at the Japanese reactors were chemical,not nuclear,"Brook said,adding that"People don't understand that their bodies are radio-activated,the food that they eat,and the rocks the air and the sunlight,all of that are natural radiation they experienced."
Graham Andrew,an official from the International Atomic Energy Agency (IAEA) said,"To better prevent an accident like the crisis at the Fukushima Daiichi nuclear power plant in Japan,there must be a high regard  given to matters of safety."
Denis Flory,an IAEA vice director-general and head of the Department of Nuclear Safety and Security,said,"What is needed is that whatever development of nuclear energy cannot be seen without a very strong safety culture,with a very strong safety authority with very strong safety standards,so these are  two aspects which must go hand-in-hand and which must go together with a very strong transparency (透明) process."
Flory said he believes that since Fukushima,more and more people have considered that strong safety measures are"the only way forward"when it comes to developing nuclear energy.
Currently,the IAEA's nuclear safety standards are not a must for member states.However,if a member state is receiving IAEA technical cooperation support,it is required to adopt the agency's safety standards.
It will likely take some time to come to lasting agreements on how nuclear safety must develop,but Flory said that a minister-level conference planned for June will mark the beginning of a process of building stronger standards.

67.Which word best describes Brook's feeling about Japan's nuclear crisis?B
A.Worried.   B.Calm.    C.Terrified.  D.Confused.
68.The underlined"regard"is closest in meaning toB.
A.respect    B.concern   C.standard    D.education
69.What does the underlined"two aspects"refer to?C
A.A strong safety authority and safety standards.
B.A strong safety culture and a strong safety authority.
C.Development of nuclear energy and a strong safety culture.
D.Development of nuclear energy and a strong transparency process.
70.What can be inferred from the last paragraph?B
A.It is impossible to cut down the use of nuclear power.
B.The final agreements on nuclear safety standards are yet to come.
C.Member states of the IAEA have to adopt the agency's safety standards.
D.A minister-level conference is being held to discuss stronger safety standards.
