Fatu Kekula is a hero. The 22-year-old Liberian nursing student, in her final year, managed to save the members of her immediate family from the Ebola virus, all without the help and convenience of a hospital.
Kekula reduced the rate to 25 percent. Four of her family members were infected with the virus. Her father, Moses, her mother, Victoria, her sister, Vivian and her 14-year-old cousin, Alfred Winnie. Sadly, Kekula’s cousin succumbed to the virus. It’s also impressive to note that while Kekula was treating her family members she managed to avoid Ebola entirely.
On July 27, Kekula’s father, Moses, went to a hospital in Kanata, after his blood pressure rose sharply. The only reason the hospital had a bed to offer him was because someone had just died. But the staff in the hospital didn’t realize the patient died from an Ebola infection. Shortly, after he was admitted to the hospital, Moses developed a fever, started vomiting and was suffering from diarrhea. Once nurses started dying of Ebola, the hospital shut down and Moses had to leave. Kekula drove 90 minutes to Monrovia, the capital of Liberia, to seek treatment. Three hospitals turned them away because there is no spare bed for patients at all.
Kekula made the drive back to Kanata to another hospital. They told Moses he had typhoid fever and did very little to treat him. So Kekula took him home. Once he was there, he infected three other family members. Her mother, sister and their cousin who was living with them.
Kekula only lost one patient, her cousin. Her method proved so effective that international aid workers, including UNICEF, began teaching it to others in West Africa who may not be able to get to hospitals for treatment.
Her father, mother and sister were already recovering when space became available at the JFK Medical Center on August 17. Alfred passed away at the hospital the next day. Kekula’s father, Moses said, “I’m very, very proud. She saved my life through the almighty God.”What is the best title for the passage?

The preventive measures for forest fires include some preemptive(抢先)methods that can help reduce the risks of fires and control their severity and spread，and thus, maintain ecological balance and protect resources．Close monitoring of forest fires caused by natural factors can help prevent their spread to a large extent．To contain forest fires，fire departments usually use water and chemical fire retardants(抑制剂)that can be dropped from planes and helicopters．To control the spread of a wildfire．firefighters usually create a control line by removing all fuel from an area so that the fire cannot travel across it．
Controlled burns are often employed by government authorities to reduce fuel buildup，and clean up the fallen leaves，and thus，prevent the spread of forest fires to a vast area．Regular controlled burns can also help maintain biodiversity(生物多样性)，as the smoke and heat produced in the process can facilitate(促进)the growth of seeds of certain plant species．Apart from these，responsible human behavior can help reduce the number of forest fires to a great extent．In fact，we can reduce the number of wildfires dramatically by not leaving behind any source of fire in the forest.
Forest fires can affect climate and weather to a great extent，besides causing severe damage to valuable trees．Wildfires can increase the level of greenhouse gases(water vapor, carbon dioxide，etc)，and therefore increase pollution and global warming．However, they are also an important part of the ecosystem，and many plants depend on the heat and smoke generated by wildfires for their growth and reproduction．But large wildfires can cause extensive damage to the ecosystem，which again highlights the importance of effective control and prevention of forest fires·What may be the best title for this passage?

A controlled forest fire may play a positive role because ________________.
| A．a new forest will appear soon |
| B．it promotes the development of some seeds |
| C．nature keeps its balance only by wildfires |

Scientists have been puzzled by the phenomenon that migrating birds fly not just in groups all the time, but in "V" formations and they have tried to figure out what benefit birds get from this particular formation. Now, a research group from University of London may have found the answer ― migrating birds fly in a "V" to save energy, according to a study published in the journal Nature.
When a bird flaps(振翅) its wings, it stirs the air around it and causes it to move indifferent directions. Scientist found in the study that the air creates an upward-moving wave at the tips of the wings, which means that if a bird flies around the wingtips of another bird, it can get a boost（抬高） from the rising air and therefore use less energy to stay in the air.
Apart form the "free ride" strategy, scientists were also surprised to observe that migrating birds timed their wing beats and adjusted their positions in a very precise way to maximize the lifting effect while avoiding areas where the air move downward.
"They're able to sense what's going on from the bird in front, where this 'good air' is coming from and now how to position themselves perfectly in it," lead researcher Steven Portugal told BBC.
In fact, the "V" formation has long thought to help birds fly more efficiently(效率搞地). A previous study showed that birds' heart rates went down when they were flying together in a "V" formation. Jet fighters were also found to be able reduce their energy use by up to 18% by staying near the wingtips of other jet fighters. Both of these findings led scientists to suspect that the "V" formation had an efficiency purpose, but until now they still lack proof.
"For scientists, the new study provides an insight into an interesting natural phenomenon. But it could mean even more for aircraft companies — helping them understand how they can imitate that with their plane formations to save fuel, said Portugal."What is the author's purpose in writing this article?
| A．To explain how birds benefit from migration. |
| B．To introduce how migrating birds find their way. |
| C．To tell some applications of migrating birds' "V" formations. |
| D．To report new findings about migrating birds' "V" formations. |
According to the recent study, when birds migrate .
| A．they don't change their lead birds during the whole journey |
| B．they fly in "V" formations to protect themselves against enemies |
| C．they form the shape of a "V" to make best use of the lifting effect |
| D．the air they stir around makes it hard for the birds behind to fly fast |
What is the significance of the new study according to this article?
| A．It might inspire aircraft companies to think of ways to improve efficiency. |
| B．It has proved that the "V" formation can improve in efficiency in many fields, |
| C．It has led scientists to discover that birds' heart rates go down when they fly in a "V". |
| D．It shows that the best formation of jet fighters in battle should be a "V" formation. |

Scientists in UK have grown a living human "brain". The team at Aston University created tiny bunch of cells which act like a mini nervous system.
They believe it could help find a cure for worse mental conditions like Parkinson’s disease. Professor Michael Coleman is leading the research program. He explained, "We are aiming to be able to study the human brain at the most basic level, using an actual living human cell system. Cells have to be alive and operating efficiently to enable us to really understand how the brain works. "The experiment involves changing cells from a cancer tumour (肿瘤）and making them behave like brain cells.
Although far from finished, researchers hope the false brain cells will give them a greater understanding of how real brains work. This, in turn, could significantly further research into conditions which affect the brain. Neil Hunt, chief leader of the research group, said, "It is still very early days, but in the future the research could lead to a useful tool for looking into dementia (痴呆)."
The technique could also provide a way to carry on animal test and is being supported by the Humane Research Trust (HRT). The scientists predict that over the next ten years a million people will develop dementia. Professor Coleman believes their findings could change this. He said，"We hope our research will provide scientists with a new and highly relational human experimental model to help them understand the brain better and develop new drugs to control the related disease. However, the biggest challenge at present is that we are greatly short of fund, which will slow our research."UK scientists grow a living human "brain" in order to ______.
