Last Friday, we went to Beijing Survival Island to go on an outing, that left us with a deep impression.

Early in the morning, we gathered the school gate and the school bus takes us there. In the way, we talked and laughed, full of excitement. Upon arrive, we were attracted by various activities and got involved immediate. The monkey bars were really challenging. One of the boys managed to make it with the encouragement of her classmates. I was interested in making cakes. I was being taught to make my first cake on my own! At lunchtime, we sat around, enjoying the delicious food. Everyone had the good time.

We really enjoyed our stay there. Before we left, we had a photo taken to record the unforgettable days.

A new report found 46 percent of meals are eaten alone in America. More than half (53%) have breakfast alone and nearly half (46%) have lunch by themselves. Only at dinnertime 2. we eating together, 74%, according to statistics from the report.

"I prefer to go out and be out. Alone, but together, you know?” Bechtel said, 3. (look) up from her book. Bechtel, who works in downtown West Palm Beach, has lunch with coworkers sometimes, but like many of us, too often 4. (work) through lunch at her desk. A lunchtime escape allows her to keep a boss from tapping her on 5. shoulder. She returns to work feeling energized. "Today, I just wanted some time to myself,” she said.

"It's a chance for self-reflection. You return to work 8. (refresh) and with a plan.''

That freedom 9. (choose) is one reason more people like to eat alone. There was a time when people may have felt awkward about asking for a table for one, but those days are over. Now, we have our smartphones to keep us company at the table. "It doesn't feel as alone as it may have before all the advances in technology," said Laurie Demeritt, 10. company provided the statistics for the report.

    If you work hard to have a positive attitude, you might be surprised by how much better you feel about yourself and life in general. 1. The less stress you feel, the better you will feel generally. So if you’ve been feeling tired, think about the good, put on a happy face and you just might feel better soon.

But how can you have a positive attitude when life is hard? It’s more than just turning life’s lemons into lemonade. 2. But it’s worth it. Here are some ways you can develop and maintain (保持) a positive attitude even in the midst of life’s troubles.

3.It just means being an optimist and looking for the good in things, rather than being a pessimist (悲观者) and focusing on the bad in things. Sometimes your view can make all the difference in the world.

Identify (确认) those areas of your life that might not be going so well. 4. Focus on one area at a time and think of ways you can find the positive in them.

Smile and laugh! Yes, it can be that simple. Learn to love life, no matter what’s going on. Smile at others and they will smile back at you. 5.Sometimes laughter really is the best medicine.

Exercise! Get off the couch and get moving. Being active and healthy can give you a completely different attitude to life.

    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.
