14.Tu Youyou has become the first Chinese woman to win a Nobel Prize,for her work in helping to create an anti-malaria(疟疾) medicine.The 84-year-old's route to the honour has been anything but traditional.In China,she is being called the"three nos"winner:no medical degree,no doctorate,and she's never worked overseas.
In 1967,malaria,a then deadly disease,spread by mosquitoes was decimating Chinese soldiers fighting Americans in the jungles of northern Vietnam.A secret research unit"Mission 523"was formed to find a cure for the illness.Two years later,Tu Youyou was instructed to become the new head of"Mission 523".
"Mission523"read ancient books carefully for a long time to find historical methods of fighting malaria.When she started her search for an anti-malarial drug,more than 240,000compounds(化合物) around the world had already been tested,without any success.Finally,the team found a brief reference to one substance,sweet wormwood(青蒿),which had been used to treat malaria in China around 400AD.The team took out one active compound in wormwood,and then tested it.But nothing was effective until Tu Youyou returned to the original ancient text.After another careful reading,she changed the drug recipe one final time,heating the compound without allowing it to reach boiling point.
After the drug showed promising results in mice and monkeys,Tu Youyou volunteered to be the first human recipient of the new drug."
In any case,Tu Youyou is consistently praised for her drive and passion.One former colleague.Lianda Li,says Ms Tu is"unsociable and quite straightforward",adding that"if she disagrees with something,she will say it."
Another colleague,Fuming Liao,who has worked with Tu Youyou for more than 40years,describes her as a"tough and stubborn woman".Stubborn enough to spend decades piecing together ancient texts,she applies them to modern scientific practices.The result has saved millions of lives.

52.According to Para.I,we can learn thatC.
A.Tu is the first woman to win a Nobel Prize
B.Tu has a medical degree
C.Tu's road to success is not traditional

分析 本文介绍了中国第一个诺贝尔医学奖获得者屠呦呦并讲述了她利用青蒿素治疗疟疾的研究过程以及周围的人对她的评价.

解答 52.C 细节理解题.根据本段第二句The 84-year-old's route to the honour has been anything but traditional.句中的"anything but"意为"绝不…",可知屠呦呦的成功之路和传统的成功之路完全不一样.故C正确.
53.B 猜测词义题.根据句中a then deadly disease可知当时疟疾是一种致命的疾病,这种并可以导致人死亡.所以本句In 1967,malaria,a then deadly disease,spread by mosquitoes was decimating Chinese soldiers fighting Americans in the jungles of northern Vietnam.中的下划词意为"killing",指这种疾病正在杀死在越南作战的中国士兵.故B正确.
54.D 细节理解题.根据第三段第二句When she started her search for an anti-malarial drug,more than 240,000 compounds(化合物) around the world had already been tested,without any success.屠呦呦实验了二十四万多种化合物,但是都没有成功.结果证明这些化合物对于疟疾这种病是无效的.故D正确.
55.A 推理判断题.根据文章倒数第二句Stubborn enough to spend decades piecing together ancient texts,she applies them to modern scientific practices.可知屠呦呦性格很固执,固执地研究了几十年的古代典籍.根据第三段第二句When she started her search for an anti-malarial drug,more than 240,000 compounds(化合物) around the world had already been tested,without any success.屠呦呦实验了二十四万多种化合物,这说明她很努力认真,对于自己的研究项目很投入.故A正确.

4.Are you concerned about the effect of the haze(雾霾) in Singapore on the health of your children?Then you should read the following passage.
"Young children,especially those with lung or heart illness,should avoid outdoor activity at PSI(Pollution Standards Index---used in Singapore) levels above 100,"says Dr Biju Thomas.
The immune system(免疫系统) of children is not mature.(36)AExposure to the haze can result in symptoms such as a blocked nose,dry throat,breathing difficulty,and so on.
Children who are exposed to the haze and experience any of these symptoms which are not serious should recover on their own in time if they limit their exposure to the haze.(37)CTo keep children safe during the haze in Singapore,parents should keep doors and windows closed at home.Ensure children drink plenty of pure water every day.(38)G
 The answer is that there aren't any N95 masks designed for use by children.That's because these masks are made to create a seal(密封) around the mouth and nose of the adult user so particles(颗粒) can not get in.(39)DSurgical masks may not offer enough protection from the harmful particles in the haze,which is very small (2.5 microns or less).There is usually some gap between the surgical mask and the face,through which the haze particles may easily get in.(40)FHowever,if it is necessary to take children outdoors during a haze,parents may wish to offer children's surgical mask to their children,if it brings them comfort,such as filtering out the smell from the haze.

A.So during a haze,children are especially at risk.
B.Allow children for regular travels from one building to another.
C.However,if the symptoms continue,they should ask a doctor for help.
D.The available N95 masks may not fit tightly on the face of a child.
E.So you can use a conditioner instead of opening the windows regularly.
F.So it is best to keep children indoors to protect them from the haze when the PSI is high.
G.Are N95 masks and surgical masks suitable for children?

2.If man's best friend is a dog,then who is a dog's best friend?That would be Rover,Glow,Ivan,or Raina.These four recently donated valuable pints (品脱) of blood to their fellow dogs.And they did it without having to travel far from home.They visited an animal bloodmobile (采血车).
Similar to the Red Cross vehicles for human beings,the University of Pennsylvania's travelling veterinary (兽医的) lab goes to where the donors are to make it easier.The bloodmobile makes weekly rounds through suburban Philadelphia and New Jersey.Kym Marryott,manager of Penn's Animal Blood Bank,said,"You don't really think about it until you actually need it.Just like us,dogs need blood too."
However,not every dog can donate blood.The dogs are examined for health first.Dogs must have the correct blood type,weigh at least 55pounds and be younger than 8years old.About 150dogs participate in the program.Each donates three or four pints a year,which can help animals suffering from illnesses like cancer or an accidental injury like being hit by a car.One pint can save up to three dogs.
Sandy Lucas brought her 7-year-old black German shepherd,Raina,to the bloodmobile last week when it parked at a mall in Harleysville,Pennsylvania.The resident said she wouldn't have braved highway traffic and city parking problems to take the dog to Penn Vet's Animal Hospital in downtown Philadelphia,which is too far from her home.But the bloodmobile made it convenient to find out if Raina could donate."I was very,very thrilled when I knew she had the right blood that was needed to help another dog out,"said Sandy Lucas."We'll definitely do it again."
Just like human beings,the donors get a snack and a heart-shaped"U of P Blood Donor"sticker immediately after giving.In addition,they receive free blood checkups and dog food to take home.

28.To bring convenience to the donors,the labA.
A.has bloodmobiles visiting the suburbs
B.is built where the donors are
C.goes to the homes of the donors
D.works with the Red Cross
29.How many factors should be considered when making donations?C
A.Two.B.Three.C.Four.D.Five.
30.The example of Raina is mentioned in the passage toB.
A.stress the importance of keeping pets
B.prove the value of bloodmobiles
C.tell readers that Raina is very brave
D.show how its owner felt then
31.After giving donations,the donorsA.
A.are offered a sticker
B.receive a free physical checkup
C.get a bag of free blood
D.feel very thrilled.

9.Since the 1970s,scientists have been searching for ways to link the brain with computers.Brain-computer interface(BCI) technology could help people with disabilities to send orders to machines.
Recently,two researchers,Jose Milan and Michele Tavella from the Federal Polytechnic school in Lausanne,Switzerland,showed a small robotic wheelchair directed by a person's thoughts.
In the laboratory,Tavella operated the wheelchair just by thinking about moving his left or right hand.He could even talk as he watched the vehicle and guided it with his thoughts.
"Our brain has billions of nerve cells.These send signals through the spinal cord (脊髓)to the muscles to give us the ability to move.But spinal cord injuries or other cases can prevent these weak signals from reaching the muscles,"Tavella says."Our system allows disabled people to communicate with the outside world and also to control machines."
The researchers designed a special cap for the user.This cap picks up the signals from the scalp(头皮) and sends them to a computer.The computer interprets the signals and commands the robotic wheelchair.The wheelchair also has two cameras that identify objects in its path.They help the computer react to commands from the brain.
Prof.Milan,the team leader says his team has set two goals.One is testing with real patients,so as to prove that this is a technology they can benefit from.And the other is to guarantee that they can use the technology over long periods of time.

32.How did Tavella operate the wheelchair in the laboratory?D
A.By controlling his muscles.
B.By talking to the machine.
C.By moving his hand.
D.By using his mind.
33.Which of the following shows the path of the signals described in Paragraph 5?C
A.scalp→computer→cap→wheelchair
B.computer→cap→scalp→wheelchair
C.scalp→cap→computer→wheelchair
D.cap→computer→scalp→wheelchair
34.The team will test with real patients toB.
A.make profits from them         B.prove the technology useful to them
C.make them live longer          D.learn about their physical condition
35.Which of the following would be the best title for the text?C
A.Switzerland,the BCI Research Center
B.New Findings About How the Human Brain Works
C.BCI Could Mean More Freedom for the Disabled
D.Robotic Vehicles Could Help to Cure Brain Injuries.
