Anna Du was walking along the beach when she noticed plastics there. She reached down to pick them up, and quickly realized there were many more tiny pieces than she could deal with. It seemed impossible to clean them all up.

Du, 12 years old at the time, tried to solve the problem like any good scientist—first, by doing a little research. That’s how she learned that 8 million tons of plastics end up in the oceans every year.

Then she got to work building something that could help solve the problem; a remote-operated vehicle(遙控潛水器), or ROV. Her ROV can move through water and find plastics on the ocean floor.

The actually cool part of Du’s ROV is the detection(探測(cè)) system. She uses a camera along with three different kinds of light to find the plastics. She also uses visible(可見(jiàn)的) light to find unnatural colors that might make the plastics stand out.

“She has a very good engineering sense to break down a problem like this and then go after it,” says engineer Casey Machado. “It sounds simple, but it’s a level of thinking that’s really amazing. ”

Du started attending public events and workshops at a university when she was five years old, and so she picked up the engineering skills necessary to build her ROV. She says actually getting her ROV to move through water well was not easy. She failed many times, but she never gave up trying and testing.

When asked about future plans, she mentions wanting to address the effects of climate(氣候) change. “I think there are a lot of problems that could be solved with new inventions,” says Du.

Du thanks her parents, who for years have taken her to student outreach activities, for supporting her interest in science, technology, engineering and math (STEM). She says she has been able to meet students and scientists there.

“I know I want to be an engineer because I like building things to help solve world problems,” says Du. “But I’m not sure what kind of engineer I want to be yet.”

【題目】

Today we can do everything with apps: pay bills, order food and shop for anything. Mobile technology means we can hold the world in our hands. However, when it comes to technology and health care, opportunities and challenges come together.

Let’s start with the ways to get health care. Telemedicine can allow a patient to use technology to see the doctor online and get a diagnosis (診斷) and instructions without leaving home.

In addition, there are many patient websites. These allow for different kinds of interactions about our health needs without involving the medical team. Setting a date with doctors and reading lab results are readily achieved by technology.

A whole new age of medical care seems likely (可能的) to come in the future. But every coin has two sides. What might be on the other side of techno-health care?

Firstly, we should think about the health care experience as a whole. A usual visit to a doctor begins with a receptionist (接待員) , who can see and tell how a patient is doing, This may influence the treatment effect. It’s unlikely that a patient website will have such intuition.

Next, sharing the details of one's life requires trust, which takes time to build. This is certainly true in health care, where some of life's best and worst moments involve doctors. The human touch should not be undervalued and is unlikely to be there over the smartphone.

Lastly, test results can be difficult to understand. When someone without a medical degree sees a flagged result with no explanation on the website, there's room for all kinds of stories to form in their minds—and also great worry.

So how does medicine adapt (適應(yīng)) to the new technology age? Very talented companies are working on it .There is medical equipment(設(shè)備) that can be used at home to send necessary signs and heart sounds through telemedicine . It seems likely that some companies will find a way to explain test results.

But what it will not achieve is the warmth of human interaction and touch. Patients often need someone to listen to —and care about—their journey story, which will never be realized through a human-less technology. Technology should be a tool, but depending on it totally will most certainly have unexpected effects. Let's not allow our humanity to be one of them.

【4】The writer probably agrees that_____.

A.technology can deal with unexpected effects.

B.telemedicine can take the place of usual health care.

C.it is difficult for patients to adapt to the new technology age.

D.techno-health care should take humanity into consideration.
