Despite my teaching of love to my child,I had a(46)Dtime fighting against my selfishness.But then other thoughts(47)Athrough my mind:There could be(48)Cto grannies from their grandchildren,or undelivered bills that will be overdue.
I(49)B my six-year-old daughter and asked,"Should we stop and pick them up?"
"Of course!"She answered without hesitation.To her,it was a perfectly(50)Dthing.So I pulled over.
Cars were(51)A.Many letters were carried into the(52)Dand rolling down the road.I,with my daughter,began(53)Bthe letters.A moment later,two other cars pulled over and their drivers(54)Cus.They stopped their cars on each(55)Dof the main road,stopping the traffic in all directions until the letters were all(56)A.
Just then,a relieved and very(57)B,young postman pulled up on his motorbike.I looked up at those (58)C hands and we all smiled.Without speaking,we knew we had done something(59)Cthat day.But the most important lesson I learnt was from my daughter.Her pure heart taught me more about the(60)Dof Christmas than I could ever teach her.

14.Sometimes people call each other"scared-cat",but have you ever thought about this expression?When a cat is frightened,its heart starts beating faster,its muscles get tense,and there are changes in the chemicals in its blood-stream.
Although the cat doesn't (41)Cthis,its body is getting ready for action.
If the danger continues,this animal will do one of the two things.It will (42)C itself,or it will run away as fast as it can.
(43)C,when people are excited,angry,scared,or aroused by other emotions,our bodies also go through many (44)B changes.Our hearts beat faster,and our muscles get tense.All of these changes make us more alert and ready to react.We,too,get ready to defend ourselves  (45)B run.

10.An oral drug,named ERDRP-0519,was invented.It is specifically designed to protect people who got infected measles(麻疹) from spreading the virus to others.Like the flu,measles spreads through the air by breathing,coughing or sneezing.There is typically a time,about two weeks,between becoming infected with the virus and the beginning of symptoms like skin rash(皮疹),runny nose,heavy cough and high fever.
"This therapy application determines the desired characteristics of the drug,which are orally available,cost-effective manufacture and high stability,"Richard Klemperer,professor of Georgia State University,told reporters last Wednesday.
"With these criteria in mind,we have developed a small drug that blocks the measles virus over the past years,which is essential for copy of the virus."
The researchers tested the drug in rats infected with canine distemper virus(犬瘟病),which is a close relative of measles virus.They found that all of the infected rats treated with the drug survived the deadly infection,showed no clinical signs of disease and developed a strong protective immune response.
The drug could be used to treat friends,family and other social contacts of a person infected with measles virus,which have not developed symptoms yet but are at risk of having caught the disease,Klemperer said truthfully.
"The emergence of strong antiviral immunity(抗病毒免疫力) in treated animals is particularly encouraging,since it suggests that the drug may not only save an infected individual from disease but contribute to closing measles immunity gaps in a population,"Klemperer said.
The researchers emphasized the drug is not intended as a substitute for vaccination,but as an additional weapon to get rid of the measles.They planned to test the drug's safety in larger animals,before moving into clinical trials in humans.
"If our next series of studies confirms that the human situation mirrors what we have seen in rats,then this drug may make a major contribution to getting rid of measles by preventing local outbreaks"Klemperer said.
Despite the existence of an effective vaccine,annual measles deaths worldwide have remained constant at around 150,000since 2007.The reasons for this are the highly infectious nature of the virus,in the developing world largely due to issues of resources,and in many developed countries in particular in the European region due to parental concerns regarding vaccination safety.

33.If a boy got infected by measles virus,he might NOT show the symptom likeD.
A.runny nose        B.bad cough
C.high fever         D.sick stomach

A.is only intended as a substitute for vaccination
B.can only save those infected individuals from disease
C.is cost-effective and high stability for curing measles
