Sixteen years ago I learned this lesson in the back of a New York City taxi cab.One day I was in a taxi and we headed(37)Dthe airport.We were driving in the(38)Blane when suddenly a black car drove out of a parking space right in front of us.My taxi driver slammed on his(39)A.slide sideways.a(chǎn)nd at the very last moment our car stopped and(40)Cthe other car by just inches!The driver of the ther car,the guy  who almost caused a big accident,looked around and started(41)Dat us.

6.A new computer treatment is being used to deal with obesity (肥胖) in children.
Connected to a small dining set,consisting of scales and a plate,a mini computer teaches children how to eat and reminds them when to stop.
"In very fat people,hunger signals from the stomach to the brain stop   functioning.But the new computer system teaches the children how to receive these messages again,"says Dr.Julian Hamilton-Shield,the Bristol University senior lecturer leading the treatment trials.
The computer,called a Mandometer,records and stores the weight loss from the plate when children eat.As the food is leaving the plate,a curve (曲線) is produced on the computer screen suggesting whether the child is eating too quickly.
"Children with weight problems often eat too quickly.We want them to eat steadily and slowly and the system teaches them to slow down.It's a bit like retraining."says Hamilton-Shield.
Obesity now represents one of the major threats to the future health of children.About one in five boys and one in four girls aged two to fifteen in England are overweight.But so far no treatments have proven effective in treating children.
The Mandometer was developed in Sweden,but at present is experiencing further development at the University of Bristol,with﹩224,400in funds from BUPA-a global health and care organization.The system could be on the market in two years time.At first,it would be managed by medical clinics.

60.The text is mainly written to explainA.
A.how a new computer treatment dealing with obesity works
B.why child obesity becomes a topic of people
C.how to lose weight with the help of computers
D.why a computer is effective in dealing with child obesity
61.The word"functioning"in paragraph 3probably meansB.
A.eating      B.working        C.lasting      D.losing
62.Obesity threats the health of children,whichC.
A.people have not cared about
B.is nothing compared with other diseases
C.is very serious
D.has led to many deaths
63.What can we learn from the text?C
A.The Mandometer will be put into market once it proves effective.
B.The Mandometer is cheap enough for every family to afford.
C.The Mandometer is still not perfect.
D.Slow eating is sure to make people lose weight.

4.The unthinkable keeps happening.The 18th hot car death of the year was recorded Thursday---on the same day a national public service campaign started.It is meant to warn parents about the dangers of leaving kids in overheated cars.In the latest unfortunate accident,a 10-month-old girl died in Wichita,Kan,after being left by her parents in a car that was parked outside her house.The baby was forgotten,according to the police.
One New Mexico teenager's creation called"Hot Seat"might someday prevent such deaths.Alyssa Chavez,a 17-year-old from Albuquerque,said she designed a warning system that might stop people from accidentally leaving their young children in the car after they get out of it.
Chavez,whose mother owns a day-care center,said she had heard about the deaths of three children in hot cars in summer."I felt that would be a good project for my eighth-grade science fair project---to find something to prevent those accidents from happening,"said Chavez.
She bought a door alarm (警報器) and began to design her new warning system.Finally,she won the science fair.And for the last three years,she's been improving the design and creating a busness plan.
The invention works in a simple but effective way.A parent places a sensor pad (感應(yīng)墊) under the cover of a baby car seat.The pad has a sensor that communicates with a key fob (飾物) carried by the parent to find out how far the parent is from the car.If the parent is more than 40feet away from the car,the pad will check to see if it feels the child in the seat.If it doesn't,the alarms will not sound.If it does,then three alarms will go off---the key fob,the parent's phone and the car alarm itself.Chavez is now trying to raise money to build a model Hot Seat.
28.What can we say about the 10-month-old girl's parents?A
A.They were too careless.
B.They treated her unkindly.
C.They had poor driving skills.
D.They were against the campaign.
29.Chavez's warning systemB.
A.was suggested by her mother
B.was designed in her eighth grade
C.works together with a door alarm
D.has helped her earn a lot of money
30.If a baby is sitting in the car,the alarms will go off whenD.
A.the car key is taken out
B.its parent gets out of the car
C.the pad feels it on the car seat
D.its parent is over 40feet away
31.What is the text mainly about?D
A.An interesting science fair project.
B.A national public service campaign.
C.An unfortunate accident in Wichita.
D.A successful invention by a teenager.
