10.We have met the enemy,and he is ours.We bought him at a pet shop.When monkey-pox,a disease usually found in the African rain forest,suddenly turns up in children in the American Midwest,it's hard not to wonder if the disease that comes from foreign animals is homing in on human beings."Most of the infections(感染) we think of as human infections staned in other animals,"says Stephen Morse,director of the Center for Public Health Preparedness at Columbia University.
It's not just that we're going to where the animals are;we're also bringing them closer to us.Popular foreign pets have brought a whole new disease to this country.A strange illness killed Isaksen's pets,and she now thinks that keeping foreign pets is a bad idea."I don't think it's fair to have them as pets when we have such a limited knowledge of them,"says Isaksen.
"Laws allowing these animals to be brought in from deep forest areas without stricter control need changing,"says Peter Schantz.Monkey-pox may be the wake-up call.Researchers believe infected animals may infect their owners.We know very little about these new diseases. A new bug(病毒) may be kind at first.But it may develop into something harmful,(有害的). Monkey-pox doesn't look a major infectious disease.But it is not.impossible to pass the disease from person to person.

29.We learn from Paragraph l that the pet sold at the shop mayB.
A.come from Columbia       
B.suffer from monkey-pox
C.enjoy being with children   
D.prevent us from being infected
30.Why did Isaksen advise people not to have foreign pets?A

B.We need to study native animals.
C.They can't live out of the rain forest.
D.They attack human beings.

A.a(chǎn) new disease        
B.a(chǎn) dangerous animal
C.a(chǎn) clear warning       
D.a(chǎn) morning call

B.may have to fight against more new diseases
C.should not be allowed to have pets

1.One morning,my husband Jerry went back to the kitchen as he just finished loading his car."I guess filling my thermos(保溫瓶) is all that I have left to do,and then I'm off."Down the drain(下水道) went the hot water that had been warming his thermos.
With a nostalgic(懷舊的) look on his face,he softly said:"Anytime I fill my thermos I think of your mom."The tone in his voice was so tender(溫柔的) as he spoke of my mother,who is sadly no longer with us.
"Oh honey,I know she's watching and listening right now with a big smile on her face,"I responded,tears in my eyes.
One morning years ago when we were leaving,mother watched as Jerry was to fill his thermos.Mom then casually said,‘Jerry,if you filled your thermos with hot water and let it sit a while,your coffee would stay hot for longer then."With her simple suggestion,his face showed that he was shocked by his own lack of common sense.Well,of course it would!
He poured out the small amount of coffee already in the thermos and refilled it with boiling hot water.Then he poured the water and refilled it with hot coffee.Mom smiled as Jerry did so.
Words of wisdom from a loving mother-in-law made an impact(影響) that will never be forgotten.She never dreamed her words would be a treasured and everlasting memory in the heart of her son-in-law.
The lasting memories don't necessarily come from major moments in life.Memories are often made during those small,ordinary times.Life is about small moments we share with friends and loved ones.
1.Which word best describes the author's feeling in Paragraph 3?D
A.Concerned         
B.Confused         
C.Interested         
D.Touched
2.The underlined part"don't necessarily"is similar in meaning toB.
A.out of the question                      
B.possibly but uncertainly
C.certainly and absolutely                  
D.without any doubt
3.The message that the story intends to convey(傳達(dá)) isA.
A.that lasting memories come from small things
B.how valuable a mother's advice is to her children.
C.what a wise woman the mother is to her son-in-law

1.In many parts of the world,cars play an important role in daily life and many societies would not exist without them.(71)E But this is the prediction made by a team of transport researchers who are taken seriously,not only by government but also by car manufacturers.
    The Human Science and Advanced Technology Institute at Loughborough in the UK is part of an international research program.(72)AThat will mean much saving,no accidents and better use of roads.The super-intelligent car in the future will drive itself.(73)CInstead,we will have a choice of cars and change them as frequently as we change our clothing.
     According to Dr.David Davis,who leads the research team,these predictions are based on the rising cost of the car culture,which had blocked up our cities,polluted our air,and caused more deaths than both world wars put together.
    Davis says.ears will be fitted with some intelligent devices(裝置)to regulate(調(diào)節(jié))the distance between one car and another.(74)GComputers are much safer drivers than people,so cars in a road train will be able to drive much closer together than cars driven by people. 
    By 2010,Dr.David Davis believes,car technology will give motorists a clear view of the road,whatever the weather conditions,by projecting an image of the road ahead on to the car's windscreen.(75)DCars will be connected by an electronic tow bar to the car in front to form"road-trains"."The front vehicle in such a train bums the normal amount."says Davis."but all the others in the train would bum about ten percent of the normal amount,and so produce about ten percent of the pollution."

A.The team there believes that by 2030 all cars will be computerized.
B.They believe that cars will become more important in 20 years.
C.And it will not be owned by one individual.
D.And by 2030,cars will travel in line,linked to each other electronically.
E.So the idea that in 20 years'time,no one will own cars may be hard to believe.
F.Every driver will use less fuel in the car he owns.
G.The car will automatically speed up,or slow down,to match the speed of the car in front.

6.Twelve years ago,I arrived in Central Florida from Puerto Rico.I had heard of a job opportunity and decided to pursue it.But it never became a reality.I quickly learned that being alone without resources in an unfamiliar city was not a comfortable situation to be in.
Once my limited funds ran out I became homeless and spent a year and a half living on the streets of Orlando.Apart from feeling not being noticed and missing my family,I had to face another challenge-hunger.
For the first time in my life,I,as a foreign man,who had lived my life in the relative comfort of the middle class,understood the desperation someone feels when they don't get enough to eat.I clearly remembered having run a distance of more than 7miles on many occasions just to make it to a local feeding program before they closed at 7pm.
Once the need for food was met,the next challenge would arise-where to find a place to sleep for the night.Fortunately,local programs like the Coalition for the Homeless,Second Harvest Food Bank and the Wayne Densch Center were an important part of my ability to survive my painful experience.
With the assistance of these programs,I was accepted by a college scholarship program through the Coalition and obtained two degrees from Valencia.
My experience has helped me understand that devoting my life to helping others offers lasting rewards.Today,I am employed as Childhood Hunger Programs Manager at Second Harvest Food Bank and oversees the summer feeding,Hi-Five Kids Pack,and Kids Café programs.I am also proud to be able to distribute(分配) food resources to those wonderful programs and help hundreds more like me.
24.What can be inferred from Paragraph 1?A
A.It was impossible for the author to get a job then.
B.Many local people were out of work in Florida.
C.Florida is not a good place for people living there.
D.The author rejected many chances to get a job in Florida.
25.Why did the author run a distance of over 7miles on many occasions?B
A.Because he didn't want to be late for work there.
B.Because he desired to get some free food to eat.
C.Because he went there to help the poor.
D.Because he helped distribute food resources to the poor.
26.Before being accepted by a college scholarship program,the authorC.
A.had lived with his relatives happily.
B.had won his degree in a university.
C.had been struggling financially.
D.had lost hope of facing the future.
27.From his experience,the author learned thatD.
A.misfortune may be an actual blessing.
B.a(chǎn) friend in need is a friend indeed.
C.where there is a will there is a way.
D.one good turn deserves another.
