1.Brain scientists at Toroiiro's Sunnybrook,Hospital are revolutionizing the way patierits with tremors are treated--without surgery or allesthetic.
  Doctors have successfully used ultrasound wave(起声波) to reach an area deep inside the brains of patients suffering from a condition known as"essential tremor",the most common movement disorder that is often resistant to medical treatment.
  With the guidance of an,MRI(核磁振成像),more than.l,000 ultrasound beams are delivered to a small target in the brain,killing the cells that cause the uncontrollable shaking.The procedure does not require a general anesthetic and the patient is awake the entire time.Although only five patients have been treated with ultrasound waves in Canada so far,experts at Sunnybrook say the procedure seems to be safe,with"limited"side effects.
  Tony Lightfoot,68,is among the Paticiits Who underwent the procedure to treat his shaky arms and hands.Many patients with tremor have a verr difficult time using their hands to eat,drink or write,and for Lightfoot.the simple tasks ofdrinking water or buttoning his shirt were hard.He said the opportunity to undergo the ultrasound treatment was a"great hope for the future".
"I am hoping to be able to write again,"he said."I am hoping to write with a cup of coffee in my hand,withorit spilling.I am hoping to sit with a friend and if he offers me a cup of tea or coffee,I can hold it instead of throwing it all over the place."
   Dr.Andres L.ozano of Toronto Westem Hospital's Krembi Neuroscience Centre,which is working together with Sunnybrook,said the results of the ultrasound wave treatmeht are immediate."As soon as we burn the cells that cause the tremor,it goes away,"he said."This is the kind of surgery that allows you to come here and go home an hour later.
   Dr Micliael Schwartz,the man researcher,said the results so far are very exciting."Here's a chance to do something without making a hole in the patient,so there is no risk of damage and yet we can achieve the same results as surger)r,"he said.

17.Dogs and other hairy mammals shake at just the right frequencies to get rid of water most quickly from their bodies-and directly on to any unlucky humans nearby.Mice do it.So do tigers and pandas.These animals really know how to shake.Frequency is the number of cycles-movements back and forth-per second.
Researchers at the Georgia Institute of Technology in Atlanta recently recorded videos of 40different animals,standing for 15different species.The scientists wanted to see how wet,hairy mammals shake off water after they get wet.The scientists say the animals shake at just the right frequencies to lose water drops as quickly as possible."I think it's pretty amazing that they can do that,"David Hu,one of the scientists,said.
This study was led by Andrew Dickerson,a graduate student in Hu's lab.His team calls this get-dry shake"nature's analogy(类似) to the spin cycle of a washing machine".Both the washing machine and shaking animals can get rid of water quickly-but animals are much faster than washing machines.For animals,this process helps them control heat in their bodies.
"If a dog couldn't dry itself,it would have to use 25percent of its daily calories to heat its body to get rid of the water,"Hu said."Every time they got wet they would get hypothermia and die."
The bigger the animal,the slower it shakes,according to Dickerson and his team.A mouse moves its body back and forth 27times per second,but a bear shakes only four times per second.
Animals'skin also helps them get rid of water.The scientists are continuing to look at how animals interact with water in the natural world.In particular,the scientists want to know how water interacts with hair-which means studying animals that have got used to life in the water,like beavers and otters.

24.Which of the following animals is not likely to be studied in the experiments?D
A.A panda. B.A tiger. C.A cat. D.A snake.
25.What can we learn from the passage?B
A.Professor David Hu led the study.
B.A dog shakes off water at a higher speed than a washing machine.
C.Animals shake off water to keep themselves cool.
D.A dog shakes off water faster than a mouse.
26.How did David Hu feel about the video?A
A.Surprised. B.Encouraged. C.Excited. D.Amused.
27.Which of the following does hypothermia probably refer to?C
A.a disease caused by hunger     
B.a disease caused by getting too hot.
C.a disease caused by getting too cold.
D.a disease caused by shaking too fast.
9.Years ago,I was watching a detective show on TV where the fingerprints of a criminal are required.The hero invites the bad guy to his home and offers him a glass of water.The man takes the glass and drinks the water.After he leaves the hero dramatically brings out a handkerchief and picks up the glass.His expressions show the satisfaction at a job well done.The bad guy will soon be arrested.
At that time,I found it amazing-how can prints on a glass identify people?My dad explained that if you were to press your thumb on an inkpad and then on a sheet of white paper you will leave a smudge or print,which no one else in the world can make.The same would be true for each of your fingers.The Chinese were the first to use a fingerprint as a type of identification-it was used as a signature on important documents,although they had no way of independently matching it with the owner.
Each print is one-of-a-kind and no two people have the same characteristic.Scientists and criminologists (those who study criminal characteristics) determine the differences between fingerprints by a careful study of their curves and not by their general shape or pattern.
In 1892,an English scientist,Sir Francis Galton,published a book on using fingerprints to solve crimes.At the same time in Argentina,a police researcher Juan Vucetich was also working towards a fingerprint classification system.However,it was in 1896that Sir Edward Henry,then serving as Inspector General of Police in India,developed the print classification system that would eventually be used globally.
Sir Edward Henry and his assistant Khan Haque discovered that all fingerprints could be systematically classified according to their general curve patterns.He divided them into three classes on the basis of their general pattern:loops (箕形纹),whorls (斗形纹),and arches (弓形纹).By counting the curve between any two points in the pattern,each of the ten fingers could be classified into a particular group.Taking the group together as a unit you have a complete system of classifying fingerprints.
In June 1897,the world's first fingerprint bureau was set up in Calcutta and in 1901,Sir Edward Henry was appointed head of Scotland Yard in London,where he applied the system.This system,called the science of fingerprint identification,is still used by police departments all over the world today with few changes.

B.how satisfied the hero was with his work
C.how careful detectives should be when working

37.Fingerprints were first used in China toA.
A.sign documents               B.capture criminals
C.show respect                 D.prove identity
38.In which country was today's fingerprint classification system developed?D
A.China         B.Scotland         C.Argentina        D.India
39.Which of the following is true according to the passage?B
A.The fingerprint classification system has experienced great changes.
B.For more than a century,fingerprints have been applied to crime solving.
C.Henry's fingerprint classification system was immediately accepted internationally.
D.By comparing the general shape of two fingerprints,one can easily tell their difference.
40.What is the best title for this passage?C
A.Detectives and Criminals

11.Until last summer I had a very comfortable life:winter vacations skiing and summer cruises(乘船游览).My parents spent a lot of money on a private school,so they could get me into a competitive middle school.Everything was about tomorrow,next year,my graduation.We never had to worry about today.
Before last summer I never thought much about the people in the world who live day to day,every day,whose lives are controlled by poverty and hunger.Then I enrolled in a two-week intensive program.We lived in a"Tribal Village,"in a hot,dry open grassland in Arkansas,a state of the south-central United States.I am a tribal member in Mozambique,a country of southeast Africa.Every meal,I make the fire for my family,and feel the flames lick up my nostrils as I blow to keep the fuel alive.I cook mush with vegetables.This is all my family is ever given.
I feed the hen and three rabbits their dinner.I grow attached to the rabbits,even though I know I shouldn't.I name them.I'm not getting enough to eat; it's time to decide whether or not to kill the rabbits.I feel pain but it's a privileged child's pain because I know I will soon be eating again.That's not true for a lot of other children around the world.
Growing up comfortably in the U.S.,I've never had to worry about my dinner,and even though this whole process was only a simulation,it changed my life.Now I believe in doing whatever I can to help find practical ways to defeat hunger.
So I've become president of Roots and Shoots,a group working to improve local environments for people and animals.I'm also working to create a program at my high school called the"Safe Passage"trip to help young people in the Guatemala City dump.And I've got plans to do more.
I'm often thinking of laboring in the hot sun and the millions who still do.Now,I try to live for today and stop worrying so much about the future.When I eat or feel full,I am grateful for this fortunate life and want to extend the same feeling to others.
I believe in offering help to those who need it.
