1 . The situation of the world’s plants is not good. One fifth of the kinds of plants are in danger of disappearing, according to a report.
“Plants are very vital to human beings,” said Kathy Willis, who led the new report. “Plants provide us with everything—food, fuel, and medicine, and they are very important for our climate controlling. Without plants we would not be here.”
The good news is that deforestation rates around the world have dropped largely since the 1950s. However, this report on the health of plants around the world shows that there is much more to be done.
The report predicts that there are now 390,900 kinds of plants. And about 21 percent of those plants are in danger of disappearing. “The good side is that we’re still discovering lots of new plants, about 2,000 each year,” said Dr. Willis. “The bad side is that we’ve seen a huge change in land cover, mainly caused by cultural activity, with a little bit of climate change in there as well.”
Human activity has a great effect on the danger of plants disappearing. As humans cut down forests to make room for agriculture, towns and cities, biodiversity is lost. This could not only affect our own food supply directly, but also affect the food web.

2 . If there had to be a father of handwashing in history, it would be Ignaz Semmelweis. While working at Vienna General hospital, the Hungarian doctor, faced with a situation in which maternal death (孕产妇死亡) in hospitals were significantly higher than local clinics, tried hard clues as to why.
Germs (细菌) were yet to be discovered, and it was still believed in the 1840s that disease was spread by bad smells in the air. So it didn’t seem a problem that trainee doctors hanging out of labs to dissect (解剖) human bodies would pop up to the maternity ward (产房) to deliver a baby without washing their hands.
Then an accidental finger cut by a knife during a dissection caused a doctor to die, seemingly of the same sign the mothers had been getting. Semmelweis assumed that something from the dead bodies was to blame, which might, through the hands of doctors, make their way into women’ s bodies during childbirth.
To test his theory, he ordered doctors to wash their hands and instruments in some chlorine solution. As a result, the death rate for new mothers dropped to about 1 percent, compared with that of as high as 18 percent before the experiment.
However, he faced great resistance, and met a sad end. People at that time didn’t think of themselves as sort of walking Petri dishes. And the majority of doctors then were from middle- or upper-class families, and thought of themselves as very clean people.
Over the next 40 years, a better understanding of germs developed, and attitudes to hygiene (卫生) gradually shifted. In 1876, the German scientist Robert Koch discovered the anthrax bacillus (炭疽), kicking off the new research field of medical bacteriology. Many more germs were later identified. Surgeons started to take handwashing seriously.
By the 1890s and into the early 1900s, handwashing moved from being something doctors did to something everybody had been told to do.

3 . When John was growing up, other kids felt sorry for him. His parents always had him weeding the garden, carrying out the garbage and delivering newspapers. But when John reached adulthood, he was better off than his childhood playmates. He had more job satisfaction, a better marriage and was healthier. Most of all, he was happier.
These are the findings of a 40-year study that followed the lives of 456 teenage boys from Boston. The study showed that those who had worked as boys enjoyed happier and more productive lives than those who had not. "Boys who worked in the home or community gained competence (能力) and came to feel they were worthwhile members of society," said George Vaillant, the psychologist (心理学家) who made the discovery. "And because they felt good about themselves, others felt good about them."
Vaillant’s study followed these males in great detail. Interviews were repeated at ages 25,31 and 47. Under Vaillant, the researchers compared the men’s mental-health scores with their boyhood-activity scores. Points were awarded for part-time jobs, housework, effort in school, and ability to deal with problems.
The relationship between what the men had done as boys and how they turned out as adults was surprisingly sharp. Those who had done the most boyhood activities were twice as likely to have warm relations with a wide variety of people, five times as likely to be well paid and 16 times less likely to have been unemployed. The researchers also found that IQ and family social and economic class made no real difference in how the boys turned out. Working — at any age — is important. Childhood activities help a child develop responsibility, independence, confidence and competence — the underpinnings (基础) of emotional health. They also help him understand that people must cooperate and work toward common goals. The most competent (能干的) adults are those who know how to do this. Yet work isn't everything. As Tolstoy once said, “One can live magnificently in this world if one knows how to work and how to love to work for the person one loves and to love one's work.”

4 . When an editor called to ask if I could photograph a story about fireflies in Mexico. I didn’t check my schedule before I said yes. I’d seen these insects light up the forests in Tlaxcala once before, and I jumped at the chance to go back.
While studying, I began exploring Mexico, crossing the country several times by bus. Now I work as a photojournalist in Mexico and along the border, documenting desperate situations that face everyday Mexicans. Though necessary and important, news stories don’t reflect the Mexico that I fell for and that is home to so many people I love. A task focused on the country’s natural beauty was a welcome reprieve for me.
I had three nights to film the magical scene in the forest. According to our guides, visitors are usually not allowed to photograph the fireflies because the presence of artificial light from electronics can affect their habits. As I started shooting, I adjusted my exposures constantly to account for the fading light. In order to get the composition that I wanted, I placed my tripod (三脚架) on a steep, rocky path and had to steady it during the long exposures. Normally this wouldn’t be a big deal, but the fireflies were very interested in the camera and, by extension, in me. I stood completely still while they were all over me-my arms, my hair, my face. From what I observed, peak (高峰时期的) firefly presence lasts for only about 20 minutes each night, so I had time for just a few tries.
On the last night everything came together. The weather cooperated. I had improved my method for focusing and composing photos in the dark with quick flashes from a powerful flashlight—and I’d grown accustomed to insects on my face.
I was rewarded with the image you see here. Each dot of light is one of several bursts that a firefly makes as it travels within a 30- second exposure. You can track the insects’ paths: Some make small circles, like those in the bottom center of the frame, while others move steadily in one direction or another.

5 . If feels like every time my mother and I start to have a conversation，it turns into an argument．We talk about something as simple as dinner plans and suddenly，my mother will push the conversation into World War？She'll talk about my lack of a bright future because I don't plan to be a doctor．And much to her disappointment，I don't want to do any job related to science，either．In fact，when I was pushed to say that I planned to major （主修） in English and communications，she nearly had a heart attack．

I understand why my mother is worried about my future major．I've seen my mother struggle to raise me on her small salary and work long hours．She leaves the house around 6：30 am and usually comes home around 5 pm or even 6 pm．However，I want her to know that by becoming a doctor，it doesn't mean I'll be successful．I'd rather follow my dreams and create my own future．
