8.It was shortly before midnight,and Dr Patricia was getting ready for bed.The phone rang on the end of the line was a woman about to break a promise.
The woman was her mother's neighbour.Flora Harris had made the neighbour swear she wouldn't tell her daughter she'd a heart attack and was in the hospital,for fear her daughter would worry.The neighbour wisely decided to disobey orders.
Harris desperately wanted to get to the hospital immediately,but she couldn't.She lives in Washington,D.C,and her mother lives in California.
For the past year a half,Harris has gone to Los Angeles every other month to take care of her mother.Flora Harris takes care of her husband,James,who's 91and has Alzheimer's disease.They live in their own home,and a caregiver comes to help them a few hours a day.
Harris is one of many Americans facing the heartache of how to take care of aging parents from afar.She's often worried,not to mention extremely busy with a demanding job,two teenage daughters and the frequent trips to California.
In some ways,Harris is lucky.She has the resources to make the trips to Los Angeles.Plus,Harris is a doctor who treats the elderly.
"But it's still tough,"she said."I can foresee what the next few years are going to look like,and it's not a pretty picture.My father's going to need diapers (尿布).There will come a time when he won't recognize me and he's easily excited.I worry he's going to be violent and hurt my mother."
So what do you do when you live a continent away for your aging,sick parents?There are no magic answers.You can hire someone to help,but you can't outsource it completely.

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.
