3 . A robot created by Washington State University (WSU) scientists could help elderly people with dementia (痴呆) and other limitations live independently in their own homes.

The Robot Activity Support System, or RAS, uses sensors installed in a WSU smart home to determine where its residents are, what they are doing and when they need assistance with daily activities. It navigates (定位) through rooms and around obstacles to find people on its own, provides video instructions on how to do simple tasks and can even lead its owner to objects like their medication or a snack in the kitchen.

“RAS combines the convenience of a mobile robot with the activity detection technology of a WSU smart home to provide assistance in the moment, as the need for help is detected,” said Bryan Minor, a postdoctoral researcher in the WSU School of Electrical Engineering and Computer Science.

Currently, an estimated 50 percent of adults over the age of 85 need assistance with every day activities such as preparing meals and taking medication and the annual cost for this assistance in the US is nearly $2 trillion. With the number of adults over 85 expected to triple by 2050, researchers hope that technologies like RAS and the WSU smart home will relieve some of the financial strain on the healthcare system by making it easier for older adults to live alone.

RAS is the first robot researchers have tried to incorporate into their smart home environment. They recently published a study in the journal Cognitive Systems Research that demonstrates how RAS could make life easier for older adults struggling to live independently.

“While we are still in an early stage of development, our initial results with RAS have been promising,” Minor said. “The next step in the research will be to test RAS’ performance with a group of older adults to get a better idea of what prompts, video reminders and other preferences they have regarding the robot.”

1. How does RAS serve elderly people?

A．Through sensors.	B．Through objects.
C．Through a mobile robot.	D．Through their daily activities.

2. What can we know about RAS?

A．It is the first robot used in daily life.	B．Its function remains to be tested.
C．It can locate people and do any task.	D．It can cook for owners on its own.

3. What’s Minor’s attitude toward the future of RAS?

A．Doubtful.	B．Negative.
C．Optimistic.	D．Uncertain.

4. What can be a suitable title for the text?

A．Elderly people leave the nursing home.

B．Smart Home Tests first elder-Care robot.

C．RAS, the first robot to make home smart.

D．Older adults have benefited from RAS.

4 . Google previously announced successful tests of machine learning systems designed to assist doctors. In one case, Google reported AI had examined eye diseases with equal accuracy to doctors. Other tests showed that machine learning can be used to study large amounts of patient data to predict future medical events.

Now the company has published two new studies showing a high level of success in identifying metastatic breast cancer. Metastatic means that cancer has spread from its main area to other parts of the body. Metastatic breast cancer is one of the deadliest, causing about 90 percent of all breast cancer deaths worldwide.

In metastatic breast cancer patients, the cancer often travels to nearby lymph nodes(淋巴结). Usually doctors examine lymph node tissue under a microscope to see whether cancer is present. Google notes that previous studies have shown that up to one-fourth of metastatic lymph node classifications end up being changed after a second examination. In addition, studies show that small metastatic material can be missed up to 67 percent of the time when examinations happen under extreme time restrictions.

Google says it created a mathematical algorithm(算法). The algorithm, called Lymph Node Assistant, is trained to find characteristics of tissue affected by metastatic cancer. When the system examined tissue images(图像), it was able to differentiate between metastatic cancer and non-cancer 99 percent of the time. In addition, the Lymph Node Assistant is highly effective at finding the positions of the cancers. Some of these positions would be too small for doctors themselves to identify. The research also showed that the algorithm method can reduce the usual time needed to examine the disease by about 50 percent.

But Google makes clear the AI-based system is not meant to replace the work of medical professionals. Instead, it is designed to reduce the number of false identifications and help doctors work faster and more effectively.

1. What is the main idea of Paragraph 1?

A．Google became a pioneer in training doctors.

B．Machine learning is able to stop future medical events.

C．Google developed artificial intelligence to help doctors.

D．Artificial intelligence cured eye diseases with equal accuracy to doctors.

2. What can we infer about metastatic breast cancer?

A．One-fourth of the metastatic breast cancer patients die in the end.

B．Metastatic breast cancer is very difficult to identify.

C．It results in 90 percent of deaths of all cancers.

D．It can be identified after a second examination.

3. What is the advantage of Google’s new mathematical algorithm?

A．It can offer effective treatment.

B．It can tell the exact positions of cancers

C．It costs 99 percent less time than before.

D．It improves the accuracy of identifying cancers by 50%.

4. What influence will the mathematical algorithm bring?

A．False identification of cancers will be avoided.

B．More effective prevention of cancers will be found.

C．The number of medical professionals will be reduced.

D．Doctors can have a faster understanding of patients’ condition.

5 . As my husband, Doug, stood on the busy New York city street to stop a taxi, I tried to protect my daughter from the cold December wind and rain. I put my head down to kiss her______face.

Frustrated and wet, my husband gave up his attempt to hail a taxi. I knew the feeling. Just after her first birthday, we were told our daughter Katie has a ________ brain illness. Since that moment, Doug and I felt like _______ in a marathon race where the finish line kept disappearing. We knew Katie was running out of ________. It had taken months before we finally had a name for the ________, but we were told only a few specialists in the world knew how to ________ it. Now, as we finally found a brilliant doctor to ________ our girl, we were in a strange city in the cold rain.

Just at the moment, a middle-aged woman _______ and said, “Pardon me? May I offer you a(n) _______?

Before we could say ________, she continued, “It’s really no ________ for me. Just get in.”

It was then that I noticed her thick Irish ________, which ________ me up like hot soup. We ________ said, “Thanks! Roosevelt Hospital, please,” as we got in her car for the ride.

“Are you going for the baby?” she asked us.

I nodded my head, holding back my _______.

At the hospital, we _______ her a dozen times for the ride. As the woman hugged me, I noticed her face was ________ with tears. She promised to pray for us before she left.

After three more visits to New York and two more _______ surgeries (手术), Katie is cured. But the voice of the Irish Angel still rang as a constant________ of a tiny ray of light that appeared in our ______ days.
