1、African wild dog
Finding a babysitter while you go out to work is, for example, an inconvenience. For the African wild dog, one of the continent's most endangered carnivores （食肉动物), it's a matter of life and death. A new research shows that once packs (兽群) fall below a certain size, they are not enough animals to both hunt food and stay at home protecting the young.
The African wild dog has declined drastically over the past century. Habitual loss (栖息地的丧失), persecution and unexplained outbreaks of disease have all been blamed. Only 3, 000 to5,000 animals remain, and the species is expected to go extinct within decades if the trend continues.
Other large carnivores such as the spotted hyena (鬣狗) face similar pressures, yet are not declining. Now Franck Courchamp of Cambridge University has found a reason why. The dog's weakness lies in its social organization.
Within each pack of up to 20 adults and pups, only the dominant male and female breed. The remaining animals help raise the pups, cooperating to hunt prey and defend the kill from other carnivores.
Because pups can't keep up on a hunt, large packs leave an adult behind to protect them from predators (捕猎者), which include lions and hyenas. But leaving a babysitter also carries costs. A smaller hunting party is less able to tackle large prey and to defend the kill. There is also one less stomach in which to carry food back to the den, and one more mouth to feed when they get there.
Courchamp investigated this awkward trade-off (权衡) by modeling how the costs of a babysitter change with decreasing pack size. This showed that packs of more than five adults should be able to feed all the pups and still spare a babysitter. But with smaller packs, either the hunting or the babysitting suffers, or the animals have to compensate by increasing the number of hunting excursions which itself carries a cost to the pack.
Field observations in Zimbabwe supported the model. Packs of five animals or fewer left pups unguarded more frequently than larger packs did. There was also evidence that when they did leave a babysitter, they were forced to hunt more often.
A pack which drops below a critical size becomes caught in a vicious circle (恶性循环), says Courchamp, who is now at Paris-Sud University. "Poor reproduction and low survival further reduces pack size, culminating in (最终造成) failure of the whole pack. " And deaths caused by human activity, says Courchamp, may be what reduce pack numbers to below the sustamable threshold. Mammal ecologist Chris Carbone at London's Institute of Zoology agrees. Maintaining the integrity of wild dog packs will be vitalin preserving the species, he says.
Steps will be taken to protect the African wild dog.

2、Travel Across Africa
For six hours we shot through the barren (荒芜的) landscape of the Karoo desert in South Africa. Just rocks and sand and baking sun. Knowing our journey was ending, Daniel and I just wanted to remember all we had seen and done. He used a camera. I used words. I had already finished three notebooks and was into the fourth, a beautiful leather notebook I'd bought in a market in Mozambique.
Southern Africa was full of stories and visions. We were almost drunk on sensations. The roaring (咆哮) of the water at Victoria Falls, the impossible silence of the Okavango Delta in Botswana.
And then the other things, dogs in the streets, whole families in Soweto livng in one room, a kilometre from clean water.
As we drove towards the setting sun, a quietness fell over us. The road was empty and we hadn't seen another car for hours. And as I drove, something caught my eye. Something moved close enough to touch them, to smell their hot breath. I didn't know how long they had been there next to us.
I shouted to Dan: "Look!" But he was in a deep sleep, his camera lying useless by his feet. They raced the car for a few seconds, then disappeared far behind us, a memory of heroic forms in the red landscape. When Daniel woke up an hour later I told him what had happened.
"Wild horses?" he said. "Why didn't you wake me up, Sophia?"
"I tried, but they were gone after a few seconds."
"Are you sure you didn't dream it?"
"You were the one who was sleeping!"
"Typical," he said, "The best photos are the ones we never take."
We checked into a dusty hotel and slept the sleep of the dead.
The horses didn't come near the car.

3、A Glass of Milk
One day, a poor boy who was trying to pay his way through school by selling goods door to door found that he only had one dime left. He was hungry so he decided to beg for a meal at the next house.
However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, "How much do I owe you?"
"You don't owe me anything," she replied. "Mother has taught me never to accept pay for a kindness," he said, "Then I thank you from the bottom of my heart. " As Howard Kelly left that house, he not only felt stronger physically, but also increased his faith in God and the human race. He was about to give up and quit before this point.
Years later the young woman became critically ill. The local doctors were baffled. They finally sent her to the big city, where specialists can be called in to study her rare disease. Dr. Howard Kelly, now famous was called in for the consultation. When he heard the name of the town she came from, a strange light filled his eyes. Immediately, he rose and went down through the hospital hall into her room.
Dressed in his doctor's gown he went in to see her. He recognized her at once. He went back to the consultation room and determined to do his best to save her life. From that day on, he gave special attention to her case.
After a long struggle, the battle was won. Dr. Kelly requested the business office to pass the final bill to him for approval. He looked at it and then wrote something on the side. The bill was sent to her room. She was afraid to open it because she was positive that it would take the rest of her life to pay it off. Finally she looked, and the note on the side of the bill caught her attention. She read these words. . .
"Paid in full with a glass of milk," signed Dr. Howard Kelly
Tears of joy flooded her eyes as she prayed silently: "Thank You, God. Your love has spread through human hearts and hands. "
Later the young woman became a famous doctor.

5、Fighting for a Brighter Future for Women
When I was asked what it means to be a woman running for president, I always gave the same answer that I was proud to be running as a woman, but I was running because thought I'd be the best president.
But I am a woman and, like millions of women, I know there are still barriers and biases (偏见) out there, often unconscious, and I want to build an America that respects and embraces the potential of every last one of us.
I ran as a daughter who benefited from opportunities my mother never dreamed of. I ran as a mother who worried about my daughter's future and a mother who wants to leave all children brighter tomorrows.
To build that future I see, we must make sure that women and men understand the struggles of their grandmothers and their mothers, and that women enjoy equal opportunities, equal pay, and equal respect.
Let us resolve and work toward achieving very simple propositions (命题): there are no acceptable limits, and there are no acceptable prejudices in the 21 st century in our country.
You can also be so proud of it, from now on, it will be unremarkable for a woman to win primary state victories, unremarkable to let a woman in a close race to be our nominee (被提名者), unremarkable to think that a woman can be the president of the United States. And this is truly remarkable my friends.
We are disappointed that we couldn't go all of the way, especially the young people who put so much into this campaign. It would break my heart if, in falling short of my goal, I in any way discouraged any of you from pursuing yours.
We always aim high, work hard, and care deeply about what you believe in. And when you stumble (绰倒), keep faith. And, when you're knocked down, get right back up and never listen to anyone who says you can't or shouldn't go on.
As we gather here today in this historic, magnificent building, the 50th woman will leave the Earth and orbit (绕轨道运行) overhead. If we can blast 50 women into space, we will someday launch a woman into the White House.
Many American young people feel disappointed at Hillary's failure to win the nomination.
