Peggy Hilt wanted to be a good mother. But day after day, she got out of bed feeling like a failure. No matter what she tried, she couldn’t connect with Nina, the 2-year -old girl she’d adopted from Russia as an infant （幼儿). The preschooler （学龄前儿童）pulled away whenever Hilt tried to hug or kiss her. Nina was physically aggressive with her 4-year-old sister, who had been adopted from Ukraine, and had violent tantrums（发脾气). Whenever Hilt wasn’t watching, she destroyed the family’s furniture and possessions. “Every day with Nina had become a struggle,” she recalls now.
As the girl grew older, things got worse. Hilt fell into a deep depression. She started drinking heavily, something she’d never done before. Ashamed, she hid her problem from everyone, including her husband.
On the morning of July 1, 2005, Hilt was packing for a family vocation, all the while swallowing one beer after another and growing increasingly angry and impatient with Nina’s deeds. “Everything she did just got to me,” Hilt said. When Hilt caught her reaching into her diaper（尿布）and smearing feces（粪便）on the walls and furniture, “a year and a half of frustration came to a head,” Hilt says. “I snapped（崩溃). I felt this uncontrollable rage.”
Then Hilt did something unthinkable. She grabbed Nina around the neck, shook her and then dropped her to the floor, where she kicked her repeatedly before dragging her up to her room, punching her as they went. “I had never hit a child before,” she says. “I felt horrible and promised myself that this would never happen again.” But it was too late for that. Nina woke up with a fever, and then started throwing up. The next day she stopped breathing. By the time the ambulance got the child to the hospital, she was dead.
Hilt is now serving a 19-year sentence for second-degree murder in a Virginia prison. She and her husband divorced, and he is raising their other daughter. She realizes the horror of her crime and says she isn’t looking for sympathy. “There is no punishment severe enough for what I did,” she told NEWSWEEK in an interview at the prison.

Most of the news in the newspapers is bad but sometimes there is a story with good news. This is one of those stories. Millions of people around the world suffer from AIDS, malaria, tuberculosis, and other serious diseases. There are medicines to treat these diseases but for people in poor countries, these medicines are too expensive to buy. When a pharmaceutical（制药的）company produces a new medicine, they receive a special license called a patent. This license means that the new medicine or drug is protected for a period of 20 years. The company that produced the drug can fix the price of the drug and no other company is allowed to produce the same drug or a copy of the drug for 20 years. At the moment, these patents operate all over the world, both in rich countries and in poor countries. The drugs companies say that they need patents so that they can get the money to pay for research to find new drugs and medicines. In rich countries people usually have enough money to pay for these drugs but in poor countries people can’t afford to buy them and cannot treat diseases like AIDS and malaria.
Last month, however, a group of experts published a report which says that patents are very bad for poor countries. The report says that drug companies do not want to find new medicines for diseases of poor people in poor countries. It says that poor countries should be allowed to buy cheap drugs without patents from other countries.
The authors of the report were lawyers, scientists and a senior director from the drug company Pfizer. Of course, the pharmaceuticals industry doesn’t agree with the report, “We need patents so that we can develop new medicines to fight disease both in the developed and developing world,” said a spokesman. But the report is the first sign that there might be a change in the patent system. This change could save millions of lives in the world’s poorest countries. This really is good news.
