There are endless motivations for human behaviour, from the basic drives for food to more complicated ones, such as sympathy, envy and anger. But none of these explain behaviours that we call compulsions (强迫症).They come from a need that is desperate and tortured (折磨). They may bring relief, but they bring little enjoyment, and while one part of our brain desperately wishes to stop them, another is afraid of stopping.
I used to view compulsions as foreign and almost frightening. But in the course of my research, two things happened. First, when I got to know people who were compulsive, their behaviour didn’t seem unreasonable at all. Second, I realized that although people with the most extreme compulsions seem like outliers (另类人), the anxiety that drives them to those extremes is universal.
Over any year, many of us find ourselves in the control of a compulsion that falls short of something that is disabling enough to qualify as a mental disorder – in fact, some compulsions are adaptive, helping us lead our lives or perform our jobs more effectively.
Like many people, maybe you feel forced to reach for your smart phone as soon as you wake up in the morning. Fortunately a growing number of experts have begun to succeed in distinguishing addictions from compulsions.
An addiction begins with a flash of pleasure accompanied with danger; it’s fun to gamble or to drink, and it also puts you at risk. Additions involve acting without planning or even thought, driven by an urge for immediate satisfaction.c-o/mpulsions, in contrast, are all about avoiding unpleasant outcomes. They are behaviours we repeat many times to relieve the anxiety brought on by the possibility of negative consequences. But the actual behaviour is often unpleasant – or at least not particularly rewarding, especially after many rounds of it.
Behind every compulsion is the need to avoid what causes you pain or anxiety. Compulsive behaviour is not necessarily a mental disorder. Some forms of it can be, and people in its control deserve to be diagnosed and helped. But many are expressions of psychological needs we all feel: to be at peace and in control, to feel connected and to matter. And if those are mental illnesses, we’re all crazy.
58. From the first two paragraphs, we know that _____. A. compulsions can bring relief as well as enjoyment
B. compulsive people will prefer unreasonable behaviour C. compulsions may be an understandable response to anxiety
D. compulsive people must be frightening and behave differently 59. The main difference between addictions and compulsions lies in _____. A. human relationships B. financial rewards C. internal drives D. social expectations 60. What’s the author’s attitude towards compulsion?

A. Objective. B. Negative. C
C. Doubtful. D. Cautious.
HIV is a tricky virus that escapes typical immune responses. During a successful immune system response to a foreign body, white blood cells produce antibodies that target the foreign body. These antibodies then mark the foreign body for destruction by other immune cells. For the most part, HIV escapes these immune defenses, but rare individuals develop antibodies that effectively block the virus. Researchers are now showing that these antibodies can also act as treatments in other HIV patients.
HIV has several ways of escaping the immune response. Unlike most viruses, HIV specifically attacks a type of white blood cell that is critical to our immune system. During reproduction, the HIV virus also picks up many new mutations (变异), which often change it enough that any antibodies produced earlier during the infection no longer recognize it.
These rare antibodies can also keep the virus from infecting new cells, which could make them an effective treatment. In animal studies, injection of low concentrations of these antibodies could act as a vaccine (疫苗) and provide protection against infection. Injections can even control active infections when combined with additional antibodies that target other molecules (分子) on the HIV surface. These findings led to humans phase 1 clinical trials to evaluate a specific antibody that targets HIV. This study revealed that a single injection of the antibody typically reduced the presence of HIV in the blood of patients who have viruses that were sensitive to the antibody.
After performing test-tube studies showing the effectiveness of the antibody, the researchers evaluated its safety in humans in a small trial. The study included two groups of participants: 14 uninfected individuals and 19 individuals with an HIV-1 infection. The researchers then tracked the clearance of the antibody by following its levels in the participants’ blood. Consistent with previous studies, HIV-1 infected individuals exhibited faster clearance of the antibody, with a half-life of 12.8 days compared to 24.0 days for uninfected participants. Despite the fast clearance, however, the antibody appeared to be effective.
Thirteen HIV-1 infected participants with the highest levels of virus received the highest dose (剂量) of the antibody. Eleven of them showed a rapid decline in HIV levels. Tracking the infection through the first weeks after treatment revealed the evolution of multiple viruses that were no longer affected by the antibody. However, these new variants (变体) generally remained sensitive to antibodies targeting other virus surface molecules.
Overall, this investigation shows the safety of injections of antibody 10-1074 in humans. Thus, researchers may be able to build a cocktail of antibodies that effectively block active HIV infections.

About 15 years ago, I taught A Problem from Hell, a book on genocides (大屠杀), to a group of 18- and 19-year-olds in a mid-west university in the US. In my class there was a young man who had spent his boyhood in Bosnia as NATO bombed his hometown. My other students, amazed by his connection to the genocide in the textbook, asked him what it was like to grow up in a war-zone. “A pretty normal childhood as you had here,” he said. “We played cards inside a lot, and when there was no bombing we kicked a ball in the street.”
In the past few years, the world has seen a rapid increase in refugees (难民), with the number hitting 60 million. Viet Thanh Nguyen’s story collection The Refugees reminds us that literature is news that stays news. Set in the Vietnamese communities in California as well as in Vietnam, the stories do not aim to surprise us with new twists or shock us with wonderful details, as war and refugee stories could easily choose to do. Rather, like the young man from Bosnia, Nguyen’s characters tell these stories because they are the only ones known to them.
Included in the collection are two of the most touching pieces, both about siblings (兄弟或姊妹) separated by geography and history. In “Black-Eyed Women”, the narrator (讲述人), a young Vietnamese woman, is visited by the ghost of her elder brother, who died young on the boat when the family took flight from the war. The tale of love and loss, violence and violation, may not be unfamiliar to the reader, but the determination of the brother’s ghost (he has taken decades to swim across the Pacific to reach America) and the sister’s abandoning herself to a half death make the story lasting.
As an echo, the closing story, “Fatherland”, explores a more complex situation between two siblings. The narrator, a young Vietnamese woman, meets her half-sister, visiting from the US for the first time. Adding to the tension is the fact that her father has named the narrator and her siblings after his first set of children. Two sisters, one American and one Vietnamese, yet named the same by the father – it may sound strange, but isn’t it the fate many refugees have to face: a life left behind, that could have been theirs; and a life in an adopted country.
The theme of doubleness – choice and inevitability (不可避免性), home and homelessness,
