【推荐2】What can you make with a 3D printer?

Theoretically speaking, you can make anything with a 3D printer, though its main uses are in industries like manufacturing, prototyping, construction and medicine. However, now hobbyists can create the _________ items at home, and many are even selling their wares online as a part time job.

3D printers were also a critical tool _________ of the COVID-19 pandemic, when PPE was in short supply. Hospitals_________ on 3D printers to supply their staff with gowns, masks and respirators, as well as to create parts for ventilators. One Seattle high school student even_________ a mask factory from his home using a 3D printer.

Now, with scientists able to create prosthetics (假肢) and implants via 3D printing, the_________ in medicine are arguably among some of the most exciting. They can also create_________ body parts like ears from stem cells, collagen and structural proteins in the human body called fibrin; this process is known as bioprinting, though much of it is still in the testing phases. _________, researchers can test pharmaceuticals easily and ethically with tissue created from 3D printers.

In the future, designers and hobbyists may not be asking the question “How do 3D printers work?” because 3D printers will likely be so _________ in our daily lives. Today, kids are being taught about 3D printing in elementary school, and many local libraries currently have the machines available, as do stores like UPS and Staples.

Honestly, the possibilities are_________ in the aerospace, electronic, medical, energy and automotive industries, where 3D printers will become even more vital tools. While this can be handy when it comes to cars, which can be customized for buyers, it is even more essential in the __________ field. Although we’re still probably 10 to 15 years away from 3D printed organs like kidneys, this scientific advancement is most definitely __________.

And __________ the opportunities in space, where the defense and aerospace 3D printing market is expected to reach $ 5. 58 billion by 2026. In the future, 3D printing could transform space exploration and space tourism by allowing astronauts to create objects__________while in space. Imagine a future in which buildings and food are created in space!

When will you be able to print nearly anything at home? We’re getting there. “We are at the __________ of a manufacturing age,” Bourell says, “which I believe may have an impact__________ that of the Information Age.”

【推荐3】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.
