2 . Virtual reality is considered as having the potential to transform how doctors diagnose and treat a number of mental illnesses, and the front lines of this revolution may be forming in China. Its market is wide open for ___________ and developers have an opportunity to leapfrog past traditional care models and make China an early adopter of VR psychiatry (精神病治疗) on a large scale.

VR psychiatric applications include immersing patients in simulations that seem real, exposing their brain—but not their body—to ___________ situations and helping them learn to train their physical and emotional responses. ___________, an alcohol-addicted patient can sit at a virtual bar without drinking, and a person too anxious to fly can ___________ takeoff and landing while staying firmly on the ground. Such treatments can yield fast, dramatic results: in one case a woman calculating heights could calmly ride an escalator after a three-hour course of VR ___________ therapy.

Researchers around the world have been _________ these technologies—with promising results. Through the end of 2016, peer-reviewed journals had published nearly 300 studies on using VR to treat mental health disorders. And then this March, JAMA Psychiatry published what researchers say is the first ever randomized controlled trial of a therapist-free VR ___________ of acrophobia, or fear of heights. It found the technology to be ___________, inexpensive and well-received by patients.

In China, treatment rates of mental disorders are low, which is partially linked to a shortage of trained professionals. World Health Organization data show China’s concentration of psychiatrists is four times lower than the global average, with only 2.2 per 100,000 people (the U.S. rate is 10.5). Another reason for low treatment rates is ___________. While similar biases exist in many countries, studies have shown people with psychiatric problems endure especially high levels of ____________ in China.

Many supporters of mental health VR think it can help ____________ both caregiver shortages and shame. Because the technology can be fully automated, it can easily scale to meet the needs of many people. And many think VR treatments could break through cultural barriers because they can take place in a ____________ place via a gamelike interface(界面), such as at home.

Despite the enthusiasm, however, experts warn that technology is no panacea(灵丹妙药). “VR can only be one part of mental health care and not the whole system,” one expert says. Even some of the technology’s strongest supporters ____________ that important safety and ethical guidelines are still lacking.

Still, with overwhelming demand for services and distrust of traditional care, ____________ health is booming in China. In psychiatry in particular, there is a relatively blank canvas for technological innovation—and VR is poised to fill a big chunk of that void(真空). If it does so, China could make significant strides to ____________ its treatment gap. It might even provide a model for other countries with shortages in their mental health care systems.

It’s a Friday morning in Boston, which means Dr. Jim O’Connell is making his rounds. He might be more comfortable inside an exam room, but that’s not where his patients are. O’Connell is one of a handful of physicians making house calls to the homeless in the city.

More than 550,000 Americans are homeless, and many have health problems but no access to care. O’Connell and his team,     1     (make) up of psychiatrists, internists, a nurse practitioner, a case manager, and a recovery coach, are doing something about it. They spend their days walking around     2     the homeless live—in parks, under bridges, and on the outskirts of town. They treat about 700 regular patients. During these rounds, O’Connell     3     usually sees about 20 patients. He knows where most of them sleep and whom to ask     4     they are missing. “I feel like I’m a country doctor in the middle of the city, you know?” he said.

O’Connell went to Harvard Medical School and was on his way to a prestigious oncology (肿瘤学) fellowship when his chief suggested he     5     (take) what was supposed to be a one-year position as the founding physician of a new health-care program for Boston’s homeless. That turned into a 33-year career at the Boston Health Care for the Homeless Program, one of the country’s     6     (large) of its kind.

“You realize, ‘You know what, I’m just a doctor. And what I can do is I can get to know you and ease your suffering, just     7     I would as an oncologist,’” O’Connell said. “You could not find     8     more grateful population.”

And his patients are grateful. “This man is unbelievable!” one remarked. “He’s like Jesus,” another added.

When asked about     9     his life might have turned out had he become a highly paid oncologist, O’Connell said, “I never think about it anymore.” Some things are more valuable than money. Just ask the man     10     gets everything from patients with nothing material to give.
