2.The current Ebola (埃博拉病毒) outbreak in western and central Africa has infected at least 3,069 people,including 1,552 dead,making it the largest outbreak in history.Ebola is a deadly virus-about 60percent of people infected with it have died.
How is Ebola doing its harm?
When a person becomes infected with Ebola,the virus damages the body's immune (免疫的) cells,which defend against infection,said a researcher at Lancaster University.But if a person's immune system can stand up to this attack,then he is more likely to survive the disease.
The patients that survive it best are those who don't get such a bad disadvantage in immune system.But if the body isn't able to get rid of this attack,then the immune system becomes less able to regulate (調(diào)節(jié)) itself.This means the immune system is more likely to run out of control,leading to a drop in blood pressure,multi-organ failure and eventually death.
What are the common symptoms of the disease?
Fever.Headache.Joint and muscle aches.Weakness.Diarrhea.Vomiting.Stomach pain.Lack of appetite.Chills.Rash.Redness in the eyes.Hiccups.Cough.Sore throat.Chest pain.Difficult breathing or swallowing.Bleeding inside and outside of the body.
How to prevent the spread of Ebola?
Ebola can be spread primarily via direct contact with patients,specifically the blood and fluids of an infected patient.
We should avoid contact with infected patients and objects such as clothing,bedding,and needles used by them.Avoid areas where infections have been reported.For now,the disease has only been confirmed in central and West Africa,four cases in America and Europe.Avoid eating wild-caught bush meat.Researchers have suspected that the disease came to humans via animals,probably through the meat of primates(靈長類).If you're in an area where the disease has been reported,avoid purchasing,eating,or handling wild game to stay on the safe side.
Wear protective medical clothing if you're around infected patients.Extreme caution is necessary.Hospital workers must use masks,gloves,goggles,and gowns,which needed to be worn at all times if you're around infected patients.
How Do People Survive Ebola?
Doctors don't know for certain who will survive Ebola,and there is no specific treatment or cure for the disease.Although in the minority,some people do recover from infection.
Our suggestions include:
Maintain your electrolytes (電解質(zhì)) and body liquid.Sports drinks can be used.Monitor your blood pressure and control it if necessary.Dropping blood pressure may be a serious sign of infection.Breathe in an oxygen-rich environment.Quickly address any symptoms of infection.Be honest about when and where you're feeling pain.

46.Ebola causes the death of a human being byC.
A.a(chǎn)ttacking him with high fever
B.regulating his immune system
C.damaging his immune cells
D.harming all his organs directly
47.What is NOT mentioned as the symptom of EbolaD?
A.Fever and chills.
B.Swallowing difficulty.
C.Loss of blood.
D.High blood pressure.
48.In order not to be infected by Ebola,we shouldB.
A.have the clothing of the infected cleaned
B.a(chǎn)void eating wild animals like monkeys
C.not travel to Africa,America or Europe
D.stay at home without going anywhere
49.It is true thatA.
A.a(chǎn) certain number of people survive Ebola
B.human has found a special cure for Ebola
C.oxygen can save infected people's lives
D.low blood pressure is surely caused by Ebola.

分析 本文屬于說明文閱讀,作者通過這篇文章向我們介紹了埃博拉病毒,當一個人被埃博拉感染的時候,病毒就傷害了體內(nèi)的免疫細胞,研究者懷疑疾病是由動物傳染給人的,很可能是通過靈長類的肉傳染,因此作者提醒人們要避免吃野生野味.

解答 46.C  細節(jié)理解題,根據(jù)第二段When a person becomes infected with Ebola,the virus damages the body's immune (免疫的) cells,which defend against infection,said a researcher at Lancaster University.可知當一個人被埃博拉病毒感染時,病毒就傷害了他身體中的免疫細胞,故選C.
47.D  細節(jié)理解題,根據(jù)第四段Fever.Headache.Joint and muscle aches.Weakness.Diarrhea.Vomiting.Stomach pain.Lack of appetite.Chills.Rash.Redness in the eyes.Hiccups.Cough.Sore throat.Chest pain.Difficult breathing or swallowing.Bleeding inside and outside of the body.可知文章中提到了埃博拉的癥狀有發(fā)燒,冷,呼吸或吞咽困難,血流到身體外面,而沒有提到高血壓,故選D.
48.B  推理判斷題,根據(jù)第六段Avoid eating wild-caught bush meat.Researchers have suspected that the disease came to humans via animals,probably through the meat of primates(靈長類).可知應該避免吃野生野味,研究人員懷疑疾病是通過動物傳染給人的,可能是通過靈長類的肉來傳染,故選B.
49.A  推理判斷題,根據(jù)倒數(shù)第二段Although in the minority,some people do recover from infection.可知有少數(shù)人從埃博拉中恢復,誤解分析:there is no specific treatment or cure for the disease;Breathe in an oxygen-rich environment;Dropping blood pressure may be a serious sign of infection可知現(xiàn)在還沒有方法來治愈埃博拉,氧氣只是一種建議,血壓下降是因為感染,因此B,C,D錯;故選A.

點評 考查學生的細節(jié)理解和推理判斷能力.做細節(jié)理解題時一定要找到文章中的原句,和題干進行比較,再做出正確選擇.在做推理判斷題時不要以個人的主觀想象代替文章的事實,要根據(jù)文章事實進行合乎邏輯的推理判斷.

20.Early one morning,more than a hundred years ago,an American inventor called Elias Howe finally fell asleep.He had been working all night on the design of a sewing machine but he had run into a very difficult problem:It seemed impossible to get the thread to run around the needle without any problems.
Though he was tired,Howe slept badlyHe turned and turned.Then he had a dream.He dreamt that he had been caught by terrible savages whose king wanted to kill him and eat him unless he could build a perfect sewing machine.When he tried to do so,Howe ran into the same problem as before.The thread kept getting caught around the needle.The king flew into the cage and ordered his soldiers to kill Howe.They came up towards him with their spears raised.But suddenly the inventor noticed something.There was a hole in the tip of each spear.The inventor awoke from the dream,realizing that he had just found the answer to the problem.Instead of trying to get the thread to run around the needle,he should make it run through a small hole in the center of the needle.This was the simple idea that finally made Howe design and build the first really practised sewing machine.
Elias Howe was not the only one in finding the answer to his problem in this way.Thomas Edison,the inventor of the electric light,said his best ideas came into him in dreams.So did the great physicist Albert Einstein.Charlotte Brone also drew in her dreams in writing Jane Eyre.
To know the value of dreams,you have to understand what happens when you are asleep.Even then,a part of your mind is still working.This unconscious(無意識的),but still active part understands your experiences and goes to work on the problems you have had during the day.It stores all sorts of information that you may have forgotten or never have really noticed.It is only when you fall asleep that this part of the brain can send messages to the part you use when you are awake.However,the unconscious par acts in a special way.It uses strange images which the conscious part may not understand at first.This is why dreams are sometimes called"secret messages to us".

21.The problem Howe was trying to solve wasD.
A.what kind of thread to use
B.how to design a needle which would not break
C.where to put the needle
D.how to stop the thread from getting caught around the needle
22.Thomas Edison is spokenof becauseB.
A.he also tried to invent a sewing machine  
B.he got some of his ideas from dreams
C.he was one of Howe's best friends        
D.he also had difficulty in falling asleep
23.Dreams are sometimes called"secret messages to ourselves"becauseA.
A.strange images are used to communicate ideas
B.images which have no meaning are used
C.we can never understand the real meaning
D.only specially trained people can understand them.

14.To have a second child or not,this is a question.
A concern about only one child is whether one child necessarily means a lonely child.Many parents of only child feel guilty of their decision to have only one child.There are no other children in the family for the child to associate with,which may lead to the child feeing lonely at times.
Another common argument against having just one child may be more spoiled than one with siblings.Many people believe that a single child will not have learned to negotiate with others,and respect the give-and-take involved in many relationships.Some think this may leave the child less capable of interacting well with people his or her own age.
Despite these arguments,the number of parents choosing to have only one child is increasing in the world.For some single-child parents,the pressures of devoting time and energy to a second child can result in them selecting have no more children.For other parents,the financial burden of having a second child may be the major consideration.Another important consideration is the increasing age at which women give birth to children.
Advocates of single-child families argue that there are advantages for the child as well as the parents.With just one child,the parents can give,and the child can receive,more quality time and attention.
However,there is no simple answer to the question of whether or not to have a second child.The circumstances affecting each set of parents are unique.The important thing,in the end,is to make a decision that both the wife and the husband feel confident.
32.What are the advantages of children with brothers or sisters?D
A.Less pressure and better energy
B.More respect and greater family wealth
C.Higher intelligence and more attention
D.Less loneliness and better social competence
33.What prevent some parents from having a second child according to the passage?B
A.Work pressures
B.Limited time,energy and money
C.The health and wealth of the first child
D.The negotiations between parents and children
34.What can we learn from the passage?C
A.The birth of a second child makes many parents guilty
B.The number of single-child parents is decreasing
C.Nowadays women delay giving birth to children
D.Family circumstances have little effect on parents'decision
35.How is the passage developed?D
A.By providing examples              
B.By listing suggestions
C.By offering descriptions              
D.By analyzing reasons.

2.Red roses were her favorites; her name was also Rose.And every year her husband sent them,tied with pretty bows.The year he died,the roses were delivered to her door.The card said,"Be my Valentine(情人),"like all the years before.
Each year he sent her roses,and the note would always say,"I love you even more this year,than last year on this day.My love for you will always grow,with every passing year."She knew this was the last time that the roses would appear.She thought,he ordered roses in advance before this day.Her loving husband did not know that he would pass away.He always liked to do things early.Then,if he got too busy,everything would work out fine.She cut away some stems,placed them in a very special vase,and set the vase beside the picture of his smiling face.She would sit for hours in her husband's favorite chair,staring at his photo and the roses sitting there.
A year went by,and it was hard to live without her mate.Loneliness and solitude had become her fate.Then,the very hour,as on Valentine's Day before,the doorbell rang,and there were roses,sitting by her door.She brought the roses in,and just looked at them in shock.Then,she went to get the telephone to call the florist(花匠)shop.The owner answered,and she asked him,if he would explain why someone would do this to her,causing her such pain.
"I know your husband passed away,more than a year ago,"the owner said,"I knew you'd call,and you would want to know.The flowers you received today were paid for in advance.Your husband always planned ahead.He left nothing to chance."
"There is a standing order that I have on file down here.And he has paid,well in advance; you'll get them every year.There is also another thing that I think you should know.He wrote a special little card…h(huán)e did this years ago.""Then,should ever,I find out that he's no longer here.That's the card…that should be sent to you the following year."She thanked him and hung up the phone,her tears now flowing hard.Her fingers shaking,she slowly reached to get the card.Inside the card,she saw that he had written her a note.Then,as she stared in total silence,this is what he wrote:"Hello my love,I know it's been a year since I was gone.I hope it hasn't been too hard for you to overcome.I know it must be lonely,and the pain is very real.If it was the other way,I know how I would feel.The love we shared made everything so beautiful in life.I loved you more than words can say.You were the perfect wife."
"You were my friend and lover; you satisfied my every need.I know it's only been a year,but please try not to grieve.I want you to be happy,even when you shed your tears.That is why the roses will be sent to you for years."
"When you get these roses,think of all the happiness that we had together,and how both of us were blessed.I have always loved you and I know I always will.But,my love,you must go on; you have some living still."
"Please…try to find happiness,while living out your days.I know it is not easy,but I hope you find some ways.The roses will come every year,and they will only stop when your door's not answered,when the florist stops to knock.He will come five times that day,in case you have gone out.But after his last visit,he will know without a doubt.To take the roses to the place,where I've instructed him,and place them where we are,together once again."
55.How did Rose feel when she received roses a year after her husband's death?D
A.Surprised and disappointed
B.Happy but confused.
C.Proud but frightened
D.Sad and puzzled.
56.What can we know about Rose's husband when he was alive?B

7.The poaching,or illegal killing,of rhinos(犀牛) in South Africa is growing worse each year.The government recently reported that a record number of rhinos were poached in 2014,a year which had more rhino killings in South Africa than ever before.
The World Wildlife Fund,or WWF,says about 20,000rhinos live in South Africa.That is more than 80percent of the rhinos in the world.Edna Molewa,South Africa's environmental issues minister,says,"During 2014,we are sad to say this,1,215rhinos were killed.This is a rise in the number of poached rhinos from 1004in 2013and indeed very worrying."
The animals are hunted for their horns(犀牛角).Many people in Asia believe the horn has curing power,which drives poachers,at all costs,mad for more horns.But there is no scientific evidence for this belief.The horn is made of keratin.That is the same thing as human hair,fingernails and toenails.
Ms.Mo1ewa said 386 suspected poachers were arrested last year,an increase from the year before.But rhino protection workers say poachers often go unpunished after arrest.South Africa's legal system is ineffective.Ms.Molewa said more needs to be done and South Africa is taking strong measures to protect rhinos.The efforts include moving some of the animals to secret places in neighboring countries."Now approximately 100rhinos have been moved to neighboring states in the SADC region during 2014and 200more rhinos will be moved this year"Molewa said.
Jo Shaw,the rhino program manager at the WWF,said,"we're talking about a loss of a hundred rhinos a month.Or more than three a day.We really need to see effective action not just at a national level but internationally."She says officials should find the criminal groups  responsible for the poaching and punish them.Government officials are to meet in Botswana in March at the Inter-governmental Conference on Illegal Wildlife Trade.

32.What do we know about rhinos?C
A.Half of the rhinos live in South Africa.      
B.Less than 1,000rhinos were killed in 2013.
C.The killing reached the highest point in 2014.
D.There are only 20,000rhinos left in the world.
33.What is the main reason for people to hunt rhinos?D
A.To get more keratin.                 B.To protect the farmland.
C.To use them for decoration.          D.To make money from horns.
34.Jo Shaw thinks thatC.
A.many criminal groups are well organized    
B.new laws are needed to punish the killers
C.rhino protection needs international cooperation
D.conferences about protecting rhinos are to be held every year
35.What can we infer from the text?A
A.Rhino protection has a long way to go. 
B.No one would like to buy horns in the future.
C.The illegal killing of rhinos will soon disappear.
D.Rhinos living in South Africa will move to other countries.

12.The French word renaissance means rebirth.It was first used in 1855by the historian Jules Michelet in his History of France,then adopted by historians of culture,by art historians,and eventually by music historians,all of whom applied it to European culture during the 150years spanning 1450-1600.The concept of rebirth was appropriate to this period of European history because of the renewed interest in ancient Greek and Roman culture that began in Italy and then spread throughout Europe.Scholars and artists of this period wanted to restore the learning and ideals of the classical civilizations of Greece and Rome.To these scholars this meant a return to human.Fulfillment in life became a desirable goal,and expressing the entire range of human emotions and enjoying the pleasures of the senses were no longer"frowned on".Artists and writers now turned to religious subject matter and sought to make their works understandable and appealing.
These changes in outlook deeply affected the musical culture of the Renaissance period-how people thought about music as well as the way music was composed and experienced.They could see the architectural monuments,sculptures,plays,and poems that were being rediscovered,but they could not actually hear ancient music-although they could read the writings of classical philosophers,poets,essayists,and music theorists that were becoming available in translation.They learned about the power of ancient music to move the listener and wondered why modern music did not have the same effect.For example,the influential religious leader Bernardino Cirillo expressed disappointment with the learned music of his time.He urged musicians to follow the example of the sculptors,painters,architects,and scholars who had rediscovered ancient art and literature.
The musical Renaissance in Europe was more a general cultural movement and state of mind than a specific set of musical techniques.Furthermore,music changed so rapidly during this century and a half-though at different rates in different countries-that we cannot define a single Renaissance style.

72.The phrase"frowned on"in Para.1is closest in meaning toD.
A.given up    B.forgotten about    C.a(chǎn)rgued about    D.disapproved of
73.It can be inferred from the passage that thinkers of the Renaissance were seeking a rebirth ofC.
A.communication among artists across Europe
B.Green and Roman architecture and sculptures
C.a(chǎn) cultural emphasis on human values
D.religious themes in art that were more abstract
74.According to the passage,why was Bemardino Cirillo disappointed with the music of his time?B
A.It was not complex enough to appeal to musicians.
B.It had little emotional impact on the audiences.
C.It was too dependent on the art and literature of his time.
D.It did not contain enough religious themes.
75.Which of the following is mentioned in the passage as a reason for the absence of a single Renaissance musical style?D
A.The musical Renaissance was defined by technique rather than style.
B.The musical Renaissance was too short to give rise to a new musical style.
C.Renaissance musicians adopted the styles of both Greek and Roman musicians.
D.During the Renaissance,music never remained the same for very long.
